FSB Problem

[yaz]

Hi,

 

i have bought a Corsair CMX512-3200C2 to use it with another CMX512-3200C2 in my ASUS A7N8X-E in Dual Channel Mode.

 

My CPU was running stable on 3200+ (amd 2500+) before I got the second memory.

 

If I run the ram in dual channel at 200 mhz, even with aggressive timings like 2-3-2-3 (CL-RCD-RP-RAS) it is stable.

 

To test that I do a cpu benchmark. But if it try to overclock my cpu from 166 mhz to 200 mhz, like it was before,

 

i get a bluescreen at the beginning of windows or at the beginning of the cpu benchmark.

 

If I set the vcore manually to a higher value the pc turns off completly at the benchmark.

 

Maybe the bios settings help:

EVEREST reads out this values:

 

DIMM1: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz) (2.5-3-3-7 @ 166 MHz) (2.0-2-2-6 @ 133 MHz)

Can I run this memory in dual channel mode ?

 

Thanks for your help!
