Not sure if brand or model makes much difference with our board since it follows the NVIDIA reference design for the most part, but it is generally touchy with these Keplers. My BIOS is v0503.

Fixing Posting and GPU Issue

After putting my beast together I also had problems getting my board to post. Not seeing any 64GB kits out there I had purchased two 32GB Vengeance RAM kits. I assumed that they would play well together. At the time I was clueless as to the cause of the posting issue. But by swapping RAM sticks in positions1 & 2. I was able to get posting to happen; but then my monitors only came to life maybe 2 out of the next 10 attempts and then not at all. My monitors kept complaining of no HDMI signal. I put the GTX670 in various PCIe slots with no better results. EVGA helped me. The problem there turned out to be the fact I had tightened my Dynatron CPU coolers too tight. Evidently the excess tightness was warping the CPU seats on the board just enough to cause PCIe anomalies. So I loosened them up to the point that they weren't pressuring the CPUs at all; but not so much that there was play between the CPUs and seats. I then tugged very gently on the CPUs to equalize pressures and re-tightened the coolers a small amount. My system posted, booted into Windows, and my monitors worked!
After the scramble to get it to post, my GPU had ended up in slot 3, so I moved it to slot 5 where I had planned to put it for better cooling distribution and because it doesn't switch down to 8x based on the presence of other cards in even numbered slots. Further tests confirmed that everything was still working.
Now at this point I was thinking that my problems were only due to CPU seat warping causing issues with the PCIe and RAM channels. I hadn't realized that I had also been dealing with some intermittent problems in the RAM itself.

My Advice

Not knowing what you've done or not and what you know or don't know... I don't wish to insult anyone's intelligence. Given that this board seems haunted at times or at least hormonal, this is what I would do taking each subsequent step if posting doesn't happen:
Clear RTC RAM. Make sure jumper ends up in correct position
Check and verify that CPU coolers are minimally tight
Reduce PCIe occupation to only the GPU. Try GPU in odd-numbered slot 5 or 7 (both are 16x, driven by CPU2, and not subject to speed switching complications)
Try GPU in odd-numbered slot 1 or 3 (both 16x/8x, driven by CPU1, and subject to speed switching complications)
Reduce RAM to a single stick in slot DIMM_A1 (the leftmost slot for for CPU1)
Swap alternate RAM sticks into DIMM_A1
Swap GPU into the alternate PCIe slot (5 or 7)
Reduce to most minimal config: only one CPU, one stick of RAM, and one PCIe card (GPU).
Single CPU must be in seat CPU1 (upper right), Single RAM stick must be in slot DIMM_A1 , and GPU must be in odd-numbered PCIe slot 1 or 3 (where it's driven by CPU1).
Try swapping in other RAM sticks into DIMM_A1 and moving GPU to the other odd-numbered slot

If you get it to post at most minimal config, then populate with additional RAM (from one kit). Begin by making a 2x config - add DIMM_B1 and test it, Then make a 4x config by adding both DIMM_C1 & DIMM_D1 and test. If that works, try adding the second CPU.

A good summary for initial boot issues:
http://www.tomshardware.co.uk/forum/261145-31-perform-steps-posting-post-boot-video-problems

2) If memory is "missing" then the first thing I would do is to reset the CMOS memory. Potentially, in trying to get the system starting, you changed essential settings and impacted this part of POST

3) ME is the Intel Management Engine which is part of Intels vPro offering. Basically it is a small computer on the motherboard supervising the operation of the system, even if the main CPUs are turned off - i.e. you can remotely start the Asus MB via this mechanism

4) With default CMOS settings, the MB shows the tarbet base frequency, which is in your case 3100MHz. If perf mode and similar things are changed, it could be different (haven't personally tried it)

5) This is normaly behavior. Even if the workload of AIDA, HWInfo etc is not big, you are executing software on your system. There is no hard affinity between the executing thread in an application abnd the physical core in the socket - shows up as a kind of random pattern. Benchmark software potentiall wakes up the CPU to get the timing operation right. I would *only* be concerned, if the system with good benchmark software under load would not go to either 3100MHz or better 3400 MHz (depending on your cooler). 3400 MHZ is the max frequency for all cores in Turbo mode. For 1-2 core under load the speed can go up to 3800 MHz. Good benchmark software for such a system is Intel's Linpack, be more critical of the results of the usual known benchmark apps - they are not optimized for NUMA boards like yours.

6)
Memory amount: This is normal
Memory is used for all kind of things like I/O devices are mapped into physical memory space. Some utilities see one POV, some have other approaches. 48 MB difference look like a PCI express card is mapped into memory space.

4 x 8 GB memory is a suboptimal configuration for this system. One of the reasons for a dual socket MB is a the increased bandwidth you might get. In this configuration the 16 cores of the 2xE5-2687W will starve for memory bandwidth to achive their regular performance. Basically, you run the 8 core socket with the memory bandwidth of a 4 core i7-3770. Either switch to 8x4 GB or 8x8GB. Systems like this are NOT designed to achieve low latency /high speed for individual threads, for these kind of apps an OC system with fewer cores is the better solution. If you need THROUGHPUT, then this system will shine and and leave all single socket systems in the dust. As an example: It is possible to read a 100GB file within 5 seconds into main memory (this is actually what I am doing with mine). Try this with an OC i7-3770K or i7-3930K, it wouldn't be possible.

To identify possible errors, I'd start with one populated socket, and go with 1 RAM DIMM and start there. Run the system under load for a few hours (linpack i.e.) and check the stability in its minimal config. Move from there by adding more memory Dimms to one socket. If all goes well, THEN add the second. If problems arise, change back to a single socket config with the "faulty" CPU and re-check stability. If stability is there, your setup might have been screwed for dual socket ops (or one CPU is indeed defect. Clear the CMOS and re-check with 2 sockets.

As said, many classic benchmark utilities are "confused" with NUMA systems or if the performance goes in regions beyond the design of the software. Some of them get actual slower (as data has to be moved via the QPI interconnect and there are WAY too many cores to choose from. Software which does not explicitly control the mapping of threads and memory to the indivual sockets and cores, will never achieve top performance on a 32 core NUMA system. Most benchmark utilities are not written in this way, which regularily might people belief that the single socket system gives more bang for the buck. This is correct if the assessement is done with these kind of software, it is not correct with properly developed software.

This is especially true for memory bandwidth performance checks .Your decline might come from the utility's inability to properly understand your topology. Check with stream benchmark. A system with 1600MHz memory should be in the 80 GB/sec range

Hey... I just made a system with this board, and I have a little bit of a problem. There is almost no info out there, so I made an account in order to join this thread. You seem to know your ****, perhaps you can even help me. In order to save myself some time, Im just going to paste the email I wrote to Galaxy

I recently purchased a galaxy GTX 670 and tried to put it into a computer with an ASUS Z9PE-D8 motherboard (latest v503 bios), two Xeon E5 2660 engineering sample CPUS, and 32gb of non-ecc ram. The galaxy card does not work. The fan comes on, it is not detected, there is no video signal.

However... The galaxy card DOES work in my friend's computer. It also DOES NOT work in another friend's (rather old) computer, both of which usually run older GTX cards.

Furthermore, one of those older cards (an EVGA GTX 260) DOES work in my computer. Indicating that the problem lies within the Galaxy 670 card, or the combination of it and the motherboard.

Other info:
- Tried every PCIE slot
- Card is not detected at a very low level, motherboard beeps when onboard video is disabled, indicating no video card found
- Absolutely no issues in another computer
- Monitor does not display the "no connection" warning, indicating that there is a connection, but screen always remains black, no flicker at any time.

I think I should just exchange this card... But what to exchange it for? What works for you?

First off, I want to thank timmeh87 for identifying that this issue exists with non-EVGA based 670's and the Z9PE-D8 motherboard!

Secondly, I figured out what the problem is. You need to enable "VGA Palette Snooping" in the BIOS and the problem should go away. If it doesn't then it is a combination of settings within my BIOS.

EDIT: Also this board rocks and I love having 24 threads in Linux and Windows.

I'm in!

And I have an issue I hope someone can help me with.

Here are my system specs:
ASUS Z9PE-D8 WS MoBo AMI bios 503
Dual Xeon 2687W CPU, each liquid cooled with Corsair Hydro H80
Dual EVGA GTX 580
64GB Kingston ECC Registered DDR3 1300 RAM (8 x 8 GB)
Enermax Platimax 1200 Watt PSU
LSI 9620 4i 4 port SAS/SATA RAID controller
4 x 2TB Seagate Constellation ES
Win 7 Ultimate

I run this box hard, crunching BOINC 24/7 full speed.

My issue:

I am getting a Windows WHEA event 19 frequently. This is a corrected machine check error. Details below:
A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Bus/Interconnect Error
Processor ID: 46

The details view of this entry contains further information.

I am not overclocking and have most bios settings to auto.

I turned off Speedstep in bios and the issue went away for four days. However, I want to know what is causing the issue and would like to be able to use speedstep.

Any ideas I can test?

Does anyone know the recommended voltage, frequency and timing settings for this CPU and RAM? I would like to try manual bios settings to see if I can get rid of or identify the cause of this issue.

Thanks in advance.

Cheers,
Chris

Hey Chris, I saw your post in my thread. I have a few suggestions with BIOS pics but photobucket isn't allowing uploads right now so I will add those later. Does your RAM run at its rated settings in auto mode? I had a very hard time getting my RAM to run properly but I'm not using ECC.

Thanks Scorpion.

It appears that the bios properly identified the RAM and set timing appropriately. I don't *think* the issue I am having is related to RAM...it is a "bus/interconnect" error. But you never know.

I would really appreciate seeing your bios settings.

My personal email is ChrisSibbald_at_Rogers.com (replace _at_ with @).

Cheers,
Chris

Did you get the H80's to fit? There's certainly more than enough room up top for the rads in that awesome case of yours, and if I remember right the pumps would nestle right in there between your RAM sticks. I was strongly considering getting your case; but settled on the CoolerMaster HAF X because it fits under my desk. I did order the H70s with Gentle Typhoon fans but then I sent them back because I found that I would have had to fabricate a mounting bracket up top... plus I was also a little concerned with how stiff those Corsair hoses are! It made me a touch apprehensive that the gymnastics required to mount them might possibly weaken them for later cracking. I'm sure they're pretty reliable tho. Cool running too. I settled for air-cooling with the Dynatron R17s. They fit nicely with hi-rise RAM and work just fine. CPU 2 is the hottest due to airflow config and it doesn't get over 50C with heavy rendering or 3DMark11 tests.

Hey ChrisSibbald,

Coolers too tight...?
I mentioned to PhxTriode that my coolers are Dynatron R17s. I had never installed a Sandy Brdge CPU cooler before and I got a little enthusiastic with the spring loaded mounting screws - I had torked them a tad too tight. As a result I was having problems getting any video signals out of my EVGA GeForce 670 GPU. On a hunch Chris at EVGA told me to try loosening the CPU cooler screws. I did and Voila!, everything worked. Evidently the CPU seats on many motherboards are susceptible to very slight warpage under these conditions... leading to just enough distortion to cause marginal CPU Pin connection in the seat, and many potential symptoms. Just a thot...

Mixed RAM kits?
Sorry, not sure what RAM timings you have. But I do have some experience to share that may or may not generally help. Like you, I opted for 64GB, but probably unlike you, I was naive. When my search didn't turn up any single 64GB kit, I simply purchased two 32GB kits. My assumption was pretty basic... that since all of the RAM in the two kits had been tested at 9-9-9-24, 1T, 1.5v @1600MHZ, then all of the RAM in the two kits will work at that speed. But according to Corsair tech support, my assumption excluded the probability that sticks not tested and validated TOGETHER at a particular speed very likely won't work well together in a computer at that speed. I guess there can easily be incompatibility between kit members that's somehow due to two different integrated memory controllers in the CPUs plus mobo memory controllers next to the DIMM slots - some confusion can happen when they are overwhelmed with the shear number of modules being used (8x8).

As it happens, my system has suffered from instability, corrupted OS, and corrupted apps from the very first successful post. And early on, BIOS indicated that one stick that wasn't registering at all. So I swapped it with an adjacent one and because BIOS now picked it up, I thought things were fixed. But other vague problems, frezing, etc. persisted. Eventually after a month of use that stick acted up again by only registering half of it's capacity. Again swapping helped the BIOS see it, but Speccy and some other apps didn't... go figure.

As I'm sure you know the Auto mode in BIOS picks up several (but not all) of the XMP ratings from the sticks, and it in turn sets the motherboard to work with the RAM at those settings. But only latency, timing, and voltage are honored in that way. Frequency is not. As in my case, BIOS often arbitrarily defaults it to a lower value than rated (e.g., my 1600 RAM was set to work at 1333MHz). But you also know we are provided a way to force the frequency to a handful of common settings. I naively thought that many of my instability issues were due to my RAM not being set exactly at rated speed. Haha. So I forced mine up to 1600. But my problems with instability and corruption only increased (What the heck?!...). I had very confusing symptoms. For instance, occasionally my video driver would fail for a few seconds and then recover. Evidently my assumptions about kits were wrong. Speed rating is a little more particular. And a healthy base of RAM is necessary for a healthy system.

Now not many restarts after forcing my frequency to 1600, it would not boot into Windows, and then after a few more force quits, it wouldn't even post. I went back in and yanked out half of the RAM, making sure to include those sticks that I had swapped earlier. Then it posted and Windows loaded! Testing with Memtest86+ then helped me validate the health of each stick one at a time. That testing showed one big culprit to be the stick I had previously did the swapping with. But I also found one more bad one in that kit, plus a more mildly deficient stick in the other kit (that had remained in the computer).

So evidently my mixing of kits amped up an already bad RAM problem. Corsair tech support told me that if my problems had been simply due to mixing kits, that I could fix it. But I would most likely need to leave my notions that all of the RAM would just get along together at the rated speed. Instead I would need to manually specify some lower settings that all could work together at. They suggested for starters that I go back to 1333 and also move the supply voltage upward a little to stabilize and open things up.

So these days the stakes are higher. DD3 RAM ratings are strictly tied to the kit idea, where groupings of sticks are validated together at a particular speed. Now if a kit works well together at the tested speed, one might get lucky and have a group that could also work well together at a higher clocking. But the more RAM you have, the more "Crucial" the kit philosophy is (no pun intended... )

@timmeh87: I'm having the exact same problem but with an eVGA 670 (FTW 4GB). I tried the "Enable VGA Palette Snooping" but didn't work for me. I've tried what you tried and got the same results, the card works in another machine and the onboard VGA works fine. The monitor kicks on like it's going to work but then I get the "no signal" on the monitor. I've flashed both mobo and 670 BIOS to no avail.

@DrItanium: any suggestions as to what else to try in the BIOS?

I'm running 2 2687w's with 64GB RAM and twin H80's, Corsair ATX1200 PSU.

Thanks!

FutureX,

Check out my reply to ChrisSibbald (just above your post). I had the exact same symptoms and it was due to excessive tightening of the CPU cooler. A lot of motherboards are flimsy enough that strong tightening can warp the CPU mounts just enough that the (center?) pins don't contact the CPU affirmatively ... and evidently it's a possibility on this motherboard...

Looser and very even tightening may work for you.
It's always good to have something else to try.

BlackenedTush,

Thanks for the tip, it actually worked one time! Then never again...

I loosened both H80s and fired it up and it worked! Then when I restarted the computer it was back to nothing again. so I know this card works in this machine just a lot of weirdness. I also tried other slots and the "VGA palette" to enabled like I've heard. bummer. I even tried loosening the H80s some more but nothing.

Hi Guys, I just ordered one of these boards, and a couple Xeons to go with it. Now I need some help picking out RAM, I don't need a ton of capacity 32gb across the 8 dimms is fine, but I also don't want to break the bank, preferably under $250 for 8 dimms, so I'll be looking at unregistered RAM. Does anybody have any recommendations? The stuff on the QVL is either dated (discontinued), not readily available, or really expensive ($700).

I'll be using the build mainly for folding, so speed is more important than tighter timings. I wanted to go with the Samsung 30nm 2x4gb kits, because I already have one, but I heard that RAM doesn't play nicely with this board, or low-voltage RAM in general, which is unfortunate, because I was going for a low power 2P folding rig.

Any suggestions will be considered, and appreciated.

FutureX,

Come to think about it, when I first had the issue of no signal and hadn't yet figured out the seat warpage issue, I was able to get a signal a few times by switching it among PCIe slots. As recommended for VGA cards, I had originally only focused on blue slot 3, where I was able to get it working the first 2 out of 12 times. Later when I found out about the warpage I also remembered that the CPU control is split between the two CPUs. I never played around enough with the GPU slot location to test seating on CPU2, so it is possible that for me CPU2 was seated okay while CPU1 wasn't.. I'll never know.

That said, there are actually two more related things to try:

1) Even tho you have loosened the screws, there may be a difference between the seat warpage of the respective CPUs that could be exploited - where one CPU may now be seated properly while the other one isn't quite. If that is the case, switching from slot group 1-4 to slot group 5-7 or (vice versa) would tell you that. Note also that CPU1's blue slots (1 & 3) are built to autoswitch from 16x to 8x whenever its black slots (2 & 4) are occupied. I say that because it is possible in the real world, that these two slots react in a more sensitive to marginal connections in the CPU seats.

CPU1 controls slots 1 & 3 (blue, w/ autoswitch), plus slots 2 & 4 (black)
CPU2 controls slots 5 & 7 (blue), plus slot 6 (black)

2) Again even though you loosened the cooler screws, the CPUs may still need re-seating. There are three degrees of effort that you can try to accomplish that end. Thankfully I was successful simply doing "a".:

a. loosen the cooler screws as far as possible without disengaging them from the bracket. Then gently pull the cooler pump away while wiggling it, Then re-tighten marginally.
b. Remove the coolers, reseat the CPUs, replace the coolers, and re-tighten marginally
c. same as "b"; but switch the CPUs

Good luck!

I am using 64GB of Corsair Vengeance DDR3 1600. It only uses 1.5 volts. This RAM is on the ASUS Qualified Vendor List (QVL), although it has only been officially tested/qualified at 1300MHz). This list is available from the Z9PE -D8 WS product page on the ASUS website Google "asus z9pe-d8 ws". Click on the middle-of-the-page gray tab called "Memory/Devce Support"., then download the three documents found there.

I originally purchased two 32GB kits (CMZ32GX3M4X1600C10) and filled up all 8 slots. Mixing kits like this is definitely not advisable these days with the speeds that they are pushing RAM to. If you need 32GB, then purchase a single 32GB kit. Ultimately I was very fortunate because 1) I got faulty RAM from Corsair (not common), and 2) my bad RAM sticks were found in BOTH of the kits! That meant that Corsair was obligated to replace both kits entirely. And awesomely enough, they were willing to replace them with one 64GB kit! That 64GB kit works flawlessly BTW.... So I'd recommend Corsair and their Vengeance RAM.

Now lots of RAM sticks these days come with cooling fins that could easily interfere with CPU coolers. My Vengeance RAM is that way. But Corsair also makes a low profile versions. Make sure that your RAM is low profile, or that your cooler is high-rise, or the cooler doesn't extend out over the RAM slots.

annubis 1127,

I forgot to say that the Corsair Vengeance 32GB kit I mentioned above can be had for around $150-$160 on Amazon or Newegg. And while they may have other configurations not on their website, the 32GB Kit that Corsair promotes there doesn't fill all 8 slots... it's 4 x 8GB.

Also you could conceivably mix the RAM you have with some newer RAM; but it will come at a cost. You'd have to play with it in the BIOS to reach the highest common denominator (by upping the voltage and lowering the speed to maybe 1333 or even lower).

And sorry. I see now that you already knew about the ASUS QVL...

Hmm, ok, thanks, that's food for thought. I was hoping to get at least 1866, preferably 2133 out of the RAM, but that may be asking a bit much for the limited budget I have.

Are you using the RAM at its rated speed?

This is the kit I was considering before reading your reply: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231499 2x of those, it's on the QVL, is 1.5v, and resonably priced. Unfortunately they don't have any 8x4gb kits that I can see at least.

That kit got me tempted to try this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231499 Which are similar timings / volts to another g.skill 8x8gb kit on the approved list, but I'm not sure.

[edit] Just found the 8x4gb kits, looks tempting: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231502

and the kit on the QVL, but in 8x4gb variety: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231500 OOS on that one, same price as the 2133.

I dislike those heatsinks so badly though.

BlackenedTush,

Thanks for the info! I was talking with ASUS this morning and they agreed about the warpage but also thought that once it's warped it may not go back. I've removed both processors and am letting them sit for a few hours then I'll replace them and swap slots. When I first loosened the H80s the video worked right away but then never again. I've been able to get it to work in Slot 3 but I get this power cycling on boot up. It'll power on for about a second then power off, then power back on for about a second then back off...etc. Sometimes only 1 or 2 times before it continues to boot and sometimes 5-6 times. ASUS says that's hardware related so this could all be the same problem. ASUS also said that slot 3 is controlled by PLX and not a CPU. Hopefully I'm getting closer to a solution!
