System is unstable and CPU-Z is reporting wrong memory

I purchased 2 kits of Corsair TR3X6G1600C8D. I currently have 1 kit installed. However, CPU-Z is reporting that I have CM3X2G1600C8D.

 

Why is it doing this?:confused: I am running CPU-Z v1.55

 

(sorry for the large image)

Also, my system is currently unstable. I receive the BSOD when I attempt to load XMP settings and my system crashes when I attempt to run Crysis on low settings.

 

These are my current RAM settings in the BIOS

 

base clock: 133MHz

memory multiplier: 10

timings: 8-8-8-24-2

DRAM voltage: 1.64V

QPI voltage: 1.335V

 

Everything else is set to default in the BIOS

 

Initially, I assumed my video card may be the culprit. However, I spoke with EVGA and they suggested that my system memory may be causing the aforementioned problems. I downloaded EVGA OC Scanner and was able to run the program for 2 hours at 1024x768 without any artifacts.

 

If anyone could offer further insight on this issue, I would be very appreciative.

Mixing two kits together is never guaranteed. You may need to loosen the timings to run at 1600. You may want to try 9-9-9-24-2T to see if it helps. If it still does not run at that speed then you would need to drop down to 1333MHz.

Would faulty memory be causing display artifacts? Here are some photos (via droid) of my system crashing attempting to load Windows 7 Ultimate 64 bit.

What about the PSU? EVGA technical support seemed a bit concerned that the +12V rail is reading 12.365V in the BIOS (I'm using a Corsair TX950W).

I've tried a variety of timings.

 

6 modules (12GB), DRAM voltage @ 1.64V, QPI voltage @ 1.335V

8-8-8-24-2 @ 12 mem multi

9-9-9-24-2 @ 12 mem multi

8-8-8-24-2 @ 10 mem multi

9-9-9-24-2 @ 10 mem multi

8-8-8-24-2 @ 8 mem multi

9-9-9-24-2 @ 8 mem multi

 

I repeated the same process with 3 modules (6GB) and 1 module (2GB). I get the same results.

 

Initially, I thought it was my video card, but I was able to run EVGA OC Scanner once for 2 hours without any display artifacts.

 

I'm also getting significant display artifacts in the BIOS.
