Hey thanks for all the info I wasn't sure how to update the bIOS using the MEI could you shed light on thatOriginally Posted by rluker5
.I have an EVGA motherboard that isn't the greatest for oc'ing on a casual basis so I rely heavily on xtu, but it is also the easy way to test your limits before you set them in bios since, at least with my experience, it will let stock settings resume if you try an unstable overclock. Also, thanks to Aegirsson, I know that versions of xtu newer than 6.2.0.27 will likely not let you independently control the voltages of both core and cache. So you should probably download that one and save a copy of it somewhere.
You probably want the latest bios for your motherboard and be real careful with the cpu contacts on it. Those things are way more fragile than the pins on an AMD cpu. Drop that cpu in there from a few inches up and you will have troubles.
Also ram at 1.5v is fine and ram at 1.65v might be fine for most? but is way higher than the original rating of ddr3l and current official limit of 1.5 so I would start out at 1.5 to be safe and go for more later. I'm at 1.525v with 4 sticks right now and I had to lower my speed from 2400 to 2133 keeping the timings the same as an example.
Intel xtu seems to match CPUid HWMonitor very closely so I trust it more than something like AIsuite from Asus. But on my motherboard the ram settings don't work via xtu and the voltage target i.e. "Core Voltage" goes to a minimum of 1.25v regardless of where I set it(for both core and cache), but will go higher if I set it to more than 1.25v.
The voltage offset works fine either way and is the control I adjusted the most.
I start safe with the voltages for the clocks and gradually reduce them and test them with xtu's built in benchmark as a quick stress test and I've found that test's minimum passing voltage for a given clock +.015 to .025v to be pretty stable. I've also found that, while decreasing volts for a clock, if the benchmark results go down more than negligible, my chip is very close to not working and causing a reboot.
You can repeat this for cache if you want, but mine runs at stock volts at 3.7ghz and doesn't show a lot of improvement at 3.8 so I don't mess with that much. Yet.
I've gone up to 1.425v on core and cache, and later just stock on cache and 1.4v on core worked better and gave me 4.3 ghz core stable for the xtu bench but maybe not in real use. My cpu was also in the low 80c's during the bench with a 120mm aio so that's not an everyday setting for me. My cpu also does 4.2 at 1.335v which is cool enough, 4.0 at 1.225, maybe 1.23v, and does 3.8 core at 1.17v. I run all cores the same speed and from what I've been reading my chip is fairly average. Yours will likely be different one way or the other with the volts but close with the clocks. I also turned off the integrated vr faults, disabled the integrated vr efficiency mode and raised my cpu input voltage from 1.85v to 1.95v for the 1.4v, 4.3ghz stable run. Then I turned them back on and lowered the cpu input voltage since I wasn't going to be gaming with a 70 something c cpu.
I game at 4k,60 and the 5775c at 3.8 seems to be plenty for the games I am currently playing so I usually set it to that so my computer is more quiet, but that's just my preference. Also at 1.17v it stays in the low 50c's and I have my cpu fans set to rise from idle at 55c. At 4k,60 my sli 1080tis bottleneck first anyways. If I were to be playing high framerates I would use 4.2ghz all of the time.![biggrin.gif]( "biggrin.gif")
After you've found what you want from xtu, you can set it in bios, do some stability testing, set your ram, or whatever.
I delidded my previous cpu, a 4770k and that decreased my temps and let me go from 4.6ghz top oc to 4.9 but that also increased maintenance. About every year, or sometimes twice a year the cpu would start malfunctioning somewhere and I would have to pull it out, clean off the oxidized clp, reapply it and put it back in. The cpu still works fine, now in my htpc, but the cooler's screws eventually stripped and whenever there was a problem (usually NVidia driver related) I would be suspicious of the cpu. Also the way the stable volts for my 5775c seem to be spiking past 4.2ghz leads me to believe that delidding might get me 100 MHz at the expense of some resale value and extra maintenance and risk. Not worth it for my preferences right now. But a hot cpu that doesn't need a lot of volts for it's clocks would be a better candidate.
That's all I've got. Good luck with the oc and happy gaming.
Edit: just remembered, my mobo won't let me mess with the blk/reference clock at all. I just adjust the multiplier. It would let me mess with the 4770k's blk by 2-3% but not the 5775c. Maybe an Asus will let you. They seem to have the best support for this cpu with the edram oc option and all

Also I don't think you need the vga driver unless you want to use the integrated graphics which will rob the L4 from your cpu. I don't have it installed in mine. Usually windows has some basic functionality installed by default anyways.
Also with AISuite. I think it's fan controller is great. It is also a quicker way to mess with your oc that, at least with my Z87, doesn't change your bios so the oc only lasts until you turn the computer off.
But with my Z87 AISuite was reading my volts almost 100mv low compared to HWMonitor at least some of the times. With my h81 it reads accurately. I could check the Z87 again, but my daughter is really into her roblox. So you might want to keep an eye out for that. Intel XTU is pretty accurate though, even though it takes like 30 seconds to start.
And I sometimes have the problem with AISuite where it makes some random stuff on my desktop go transparent. I disable the minibar to stop this and set AISuite to not start with windows just to be sure and to speed up startup. Just in case it happens to you.
Congrats on the Z97 Deluxe. My Z87 Deluxe is the best mobo I've had, other than the 40 pcie lanes, extra 6 pin power for dgpu, and 5775c compatibility, it beats this EVGA classified in every way imo. I even put a 3.24a delta fan in some random fan port and the deluxe handled it just fine while this classified struggles with an aio water pump.
I use the usb flashing tool in the bios. I think it's called EZflash 2 or something. Used it on my Z87 deluxe and H81. Just put the bios in the usb, start the tool, select the file and there you go.Originally Posted by diggiddi

Thankx for the info, repped up. I thought I read somewhere on here not to use the USB flash method or something Also wrt to the IGP driver see below

OC is kinda classic, 4,3Ghz core (4,4 is doable but would require 1,5+v so naaah). L3 goes to 3,7Ghz 1,25v, L4 stock 1800.
I'm running on Asus Z97-AR. Memory are cheapest Crucial ballistix 1600 CL9 1,5v, managed to get them to 2133 10-11-11-28 2T.
Another burden is the L4 cache. It works correctly only when left on auto. If you select any multiplier manually it does not work. The suspicious part is that the iGPU (that I normally do not use) is still the same, but the application performance (mostly games that benefit from L4 the most) goes down a lot, to equal of having no L4 at all. The only remedy is setting back auto and making new cold start. SW restart does not fix it. Iv tried many bioses, no changed on the matter.
Anyway, even with that all, in most games it beats Skylake 6700K @ 4,5Ghz Running 3Ghz memory, so I'm quite happy with it.

Because the edram from broadwell doesn't act like a separated memory, it is only accessible by cpu or igpu workload and it's not visible to the system agent. Thus, you cannot control it like you do with normal RAM and a driver needs to be installed.
Intel has put this driver inside igpu driver, probably because edram was mainly introduced to eliminate the low speed and high latencies that bottleneck the igpu.

Cant seem to update bios, Using Asus bios updater keeps giving me AsIO.sys!!(2) error and using 2903.cap on usb flash not working either
Am I supposed to rename it?

That other procedure mentioned looks like a pain, but maybe you have to do it like that on Asus z97.
Also I installed the iris driver and it made the edram cache recognizable on xtu, although it was already seen on aida and cpuz and my performance seems about the same on the benches I had saved. Suppose I could compare benches with purepc and sweclockers to check.
But thanks for the info it is always welcome, good luck with getting everything set.
I don't know anything about renaming the bios. I remember it being finicky about usb 2.0/3.0 and which port it was in. On my z87 I put it in the green usb 3.0 port if I remember correctly and can't remember if I used a usb 2.0 or 3.0 jump drive. My z87 manual recommended a usb 2.0 for better compatibility, but took this out for the z97 deluxe manual. I know that when I updated the bios on my h81 yesterday using ezflash 2, I used a usb 3.0 jump drive in a usb 3.0 port that was directly on the motherboard and it went through first try. And they say the jump drive should be formatted to fat32 and be single partition:Originally Posted by diggiddi

I was able to flash the bios by renaming the cap file to Z97D.cap The question I have is why don't they just name it beforehand instead of making us jump through all these hoops

My original 4790k failed. I bought this Broadwell i7 chip while waiting for the replacement from Intel.
I am so happy with the efficiency of this chip, I decided to sell the replacement 4790k.
It's currently running at 38x core / 38x cache with 1866 RAM. I haven't tried dropping the voltage any lower yet because I am waiting for my new BitFenix case fans to arrive (just replaced crappy low CFM Rosewill fans).
It's currently set to 1.155v for core and 1.155v cache. The core has a +0.010v offset and cache has +0.020v offset.
I still have all power states, c-states down-clocking and over-voltage protections enabled.
After the new higher CFM fans are in, I will find out how low the voltage goes and keep it at 38x / 38x.

Guys, maybe you can help me
I had Gigabyte Z97 Gaming 5 but died few days ago, so I bought from second hand Asus Z97 Saberthoot Mark S.
PC booting, but when I trying OC, changing All Core freq to 42, state C disabled, in Windows shows all time 36.
I cant even change it in XTU
Second problem is with RAM, if I turn on XMP profile, its doesnt matter is 1 or 2, after save, PC wont boot.
I tried flash again BIOS but nothing change.
Maybe should I instal clean Windows ?
My system spec:
I7-5775C
Asus Z97 Saberthoot Mark S
2x8GB HyperX Savage 2400 MHz

As for xmp profile I've never encountered such a problem. Though I wouldn't use xmp profile anyway - its better to set ddr parameters manually. But you can try to run ur PC without overclock and with xmp first to troubleshoot the problem. If it won't help try increasing vccsa voltage, because some samples of CPU require more SA voltage to run 2400mhz memory than the others, and xmp profile usually has it increased to 1.2v(in my case). The thing is my mobo(z97-pro) won't change it when applying xmp, it will remain 0.828v, though in my case it is still almost enough to run it stable, though for prime95(and for games) I had it increased by 25mV via offset. So check it out, maybe ur mobo also doesn't change SA voltage when you apply xmp profile, which is probably for the best because 1.2V@SA is too much imo. Try increasing it gradually until you start booting and get ur memory stable in games ets.
Clearly its not OS issue... Try reseting bios first, then customizing settings once again.Originally Posted by SwagHype

How did you do it ? I kept getting errors, asIO ((2)) or something like thatOriginally Posted by SwagHype
I get answer form Asus11 - this guy is legend. I need install BIOS in Windows not in UEFI, f#$k logic. Now CPU Freq and XMP profile works.

I'm on a ASUS z97M PLUS + 5775C I can put the EDRAM on 2200 and windows read it as such.
But I get no different performance when I do so, same performance as on 1800 or AUTO. ( AIDIA64 and WINRAR benchmark ) I enabled C states and I disabled C states no difference whatsoever anybody else having these problems? Or tips?
Thanks in advance.

Thanks in advance.
I'm stable @ 3.9 GHz with the internal voltage regulator off.
All power saving features, down-clocking, power states and sleep states are still working.
8x to 39x on both core and cache @ 1.225v on both with automatic offset (looks like it bumps up to about 1.240v or 1.255v).
I'm still using crappy fans, but 3.9 GHz is perfectly fine with me.
I haven't seen the CPU over 50% while gaming yet. It's going to last me at least another 2 or 3 years.
The GPU will definitely be upgraded when Nvidia releases a new generation.
![biggrin.gif]( "biggrin.gif")
Edit:
I forgot to mention it is just a hair under 65w TDP with the 39x multiplier. It maxes out at 64.XXw TPD (approximately 65w).
