Looks like you've got it all handled nicely wink.gif

It turns out the problem comes from the Xeon W3690 CPU.

I installed back the Xeon W3690 after, I confirmed the memory and the motherboard were not damaged. I got the errors again. Memtest test number 4 fails after 3 passes with the Xeon.

The BIOS is OK, I just didn't clear the CMOS after changing the CPUs and I was getting error with the i7-920.

The memory is non-ECC, I assume that the current memory Corsair Dominator 4 x 2 GB is not playing well with the CPU or the CPU is somehow damaged.

Any thoughts on that?

I think to buy some cheap used module of DDR3 ECC memory like this one and install the Xeon with ECC memory, just to make sure that the CPU is really bad.

Am I missing something important?
What are your thoughts? Any ideas?

How's the machine doin? Having issues my kit and my W3690 (gaming rig)

Also, out of curiosity have you tried raising your ICH voltage?

I couldn't get the Xeon W3690 working. I'm running my old i7-920.
I didn't touch the ICH either. Are you running non-ecc memory modules?

The machine has been stable since I swapped the CPU.

Yeah but I don't think it's relative. My kit has always been iffy. I think there is an issue with Memtest, tbh. Like it would fail no matter what. Stopped using it and kept using Memtest HCI, Real Bench, and IBT.

My kit has been iffy too. I think the whole platform is iffy!

I ordered and now waiting on a cheap 4 GB ECC DDR3 module. I'd like to test with ECC memory and see, if this will change something. My apps are crashing and the PC is unusable.
I was planning on buying 4 x 8 GB modules to upgrade my current 12GB, because I'm out fast of memory in multi-tasking and running web, DB servers.
...and this happened. I'm disappointed.

I suspect that the non-ecc memory might be causing the issue.
I bought the CPU like 6-8 months ago and if it's dead, I'll just get rid of this system.

Any thoughts on what might be causing the issue?

I would pump 1.55v into the RAM kit. Software doesn't always give an accurate reading. Even 1.60v Make sure your VTT is at least 1.20v That'll still leave you under the .50v minimum separation between Vdimm and VTT (IMC)

Did you by any chance go over 1.65v on your memory?

I will definitely try your suggestion tomorrow or in Tuesday, when I get my memory.
post #18 of 46
Oh yeah. As long as the VTT stays WITHIN .50v of the Vdimm. I try n keep it under .40v e.g. if my ram is pulling 1.661v I try n keep my at 1.275v VTT If you have voltage terminals on your board it would be a good idea to get a multi meter and take readings. Readings at idle and readings at load, like gaming load, and CPU stability loads like IBT or P95

Got it, thanks!

On my motherboard, if I go over 1.65v I get a red warning that I might kill the CPU. So I wonder, if the CPU is no more.
post #20 of 46
no it should be fine. you mean the volt goes from green to red? lol i got that on my evga
