Incompatibility: a7v880 and VS512DDR400

[airor]

This is a rather frustrating problem. First, my system:

 

AMD Athlon XP 2200+ 1.8G

Asus a7v880 Motherboard

PNY Geforce 5600 FX Ultra

 

Memory:

(works) Kingston PC2700 ValueRAM (512MB)

(doesn't work) Corsair PC3200 Value Select (512MB)

 

I decided to upgrade my system memory by purchasing a two pack of Corsair Value Select PC3200 RAM (512x2).

 

The weirdest problem occurs, I even reformatted my hard drive and installed everything from scratch and ran all the updates from windowsupdate and newest drivers from asus and nvidia.

 

There are no conflicts in the device manager, but with the Corsair memory, I cannot run 3D acceleration. I pop out the Corsair PC3200 RAM and pop in my Kingston PC2700 and the graphics work fine. So I've isolated the problem to something with the memory brand (when I replace the memory with what I used to have, everything works)

 

Each of the memory modules by Corsair causes the same problem, whether I install them both, or I run just one. 3D acceleration is disabled.

 

dxdiag message:

Direct3D 7 test results: Failure at step 8 (Creating 3D Device): HRESULT = 0x887602eb (error code)

 

This seems like a compatibility issue. I thought I'd post here to see if anyone had anything else I could try or any clue as to what the problem might be.

Please set the memory frequency to run at DDR333 and set the Dim Voltage to 2.7 Volts and then please test the modules one at a time with http://www.memtest.org. But with the CPU you have you would need to run your memory at DDR333.

Thanks AM guy I am going to tyr that, set it to DDR333, but the DDR VCore settings are either 2.65 or 2.75, does it matter which I pick?

I would suggest 2.75 Volts!
