The card wil not boot any more so i return it to dealer were i buy it.
Look like it some serious wrong with it onboard bios led light is dead and when i try to start it so run fans 2 sek and stop.
Is it any other mobo who runs with ES co cpues ?

Supermicro X9DAi, X9DRL

Asus Z9PE D16

I think almost all boards run C0 ES

No problem thumb.gif

You might want to wait for some response of the more knowledgeable members though. I'm also in the process of resolving an issue tongue.gif

BIOS #5004 should work with SNB-EP C0.

The problem Torwar has is PCIe 3.0 x16 training related - my theory is that pre-C2 SNB-EP CPUs have problems with NVIDIA Kepler GPUs during PCIe link training. I think that full PCIe 3.0 compliance was not achieved before C2 stepping and this is why HEDT Sandy Bridge 3930/3960x did not have PCIe 3.0 as advertised. Production Xeon E5 were mostly C2, so the problem had been probably fixed before the large batches of Xeon E5 CPUs were produced. But people who have either C1 Core i7 or C0/C1 QS Xeon E5 might have issues with some PCIe 3.0 devices.

I am afraid this problem has not been really solved yet. ASUS does not make it better by not allowing to force the training to PCIe 2.0 speeds, so in the worst case you are stuck with the loop of unsuccessful PCIe 3.0 training attempts until one of them work.

Hi psyq


Can you see what's wrong here? I have 4 sticks of RAM and I tried them in various combination but I'm fairly positive that my RAM is not in dual channel.


2 sticks in - 2x 4GB




4 sticks in proper order - 4x 4GB




CineBench makes no difference. Both 18.6 points.


I'm running 2x E5-2665 @2.5GHz overclocked

Hi TheBlademaster01,

Can you run Windows? If you do not have Windows installation, you can just copy the contents on the Windows installation ISO to a USB stick and boot into the Windows setup, then go to "recover my computer" option.

Also, copy the contents of HWiNFO installation ZIP file (http://www.hwinfo.com/)

Then, after you boot Windows (or Windows setup -> "Repair my computer" -> Command Prompt", launch the HWiNFO.

Then go to memory summary - it will display the memory configuration (single / dual / quad channel)

Please let me know if it helped.

Aight, I got everything in today except the dual 2687W's. Running through a few things and making sure I understand everything before I jump into it tomorrow. Some of these are serious N00b questions so bare with me and I'd love any/all the help I can get.

1. Which of the SATA ports should I plug my 840 pro 512 into? One of the 4 gray sockets at the bottom right?

2. ASUS has a crap-ton of updates on this page (http://www.asus.com/Motherboards/Z9PED8_WS/#support_Download_30); should I download all of them and install?

3. Can anyone post their bios screens for recommended settings (what things to turn on and off?) For instance, I'm only running a single 512 SSD so I wouldn't need marvell raid crap on right?

4. Any board jumpers I should go ahead and turn on/off that are different from their shipped default?

5. I think I'm going to end up covering up the GPU slot 1 with my CPU coolers so I will probably end up putting the TITAN on #3. Is there a difference?

I'm sure I'll think of lots more but for now I appreciate any help I can get. Thanks so much!

1. Unless you are using SAS devices, you should use Intel 6 Gbit/s SATA ports (SATA #1-2 blue are 6 Gbit/s). After those two are populated, ti depends on the drivers you'll be using. With Marvell's drivers I am getting decent performance for other SSDs from Marvell 6 Gbit/s SATA ports (gray). However, if you use Windows built-in Marvell driver the results might be worse than using Intel's SATA 3 Gbit/s.

2. If you are using Windows, I recommend to update to the latest Intel RSTe (SATA) and Marvell SATA drivers. As for the rest, I do not think it is critical but it probably does not hurt either.

3. You would not need Marvell's crap if you are only using Intel's SATA ports. If you have one SSD, just connect it to Intel's SATA 6 Gbit port (blue SATA #1). Unfortunately I do not have pictures of the BIOS here and I cannot reboot right now, but the important points are as follows:

- If you are planning to use stock ECC memory, no need to change timings/voltage. But if you are using "overclocker" RAM with XMP, or you wish to overclock , you might need to enter the memory timings manually

- Ensure that the NUMA is ON (chipset configuration -> memory configuration)

- You can also configure the CPU settings for your system role in terms of RAPL (power limits). For example, if you plan to do CPU-hungry stuff, you should configure the CPU for "High Performance Server (HPC)" role, configure the CPU power management to "Performance" and, optionally, maximize the turbo power limits

- You can speed up booting by enabling UEFI-only boot and Windows fast boot - but for this to work, Windows has to be installed in UEFI mode. Same goes for Linux - if you use UEFI boot, your Linux distro has to be installed in UEFI mode.

- There are many more options, but have very specific demands I suggest to live them as-is. You can enable "above 4G decoding" PCI devices to free-up some virtual memory space below 4 GB. If you are using ECC memory, you can also enable both demand and patrol scrubbing in memory configuration to increase the robustness against simple memory errors.

4. No

5. No - but for people that have B0/C0/C1 SNB-EP Xeons slot #3 is actually more stable in terms of boot-detection / PCIe link training.

For Folding, turn NUMA OFF to gain about 10% performance
