So I bought an Asus A8V-Deluxe to match my 3000+ Venice. I Uninstalled my previous nforce2 drivers, ran driver cleaner etc. and Windows booted seamlessly and detected my new processor and motherboard.
All seems fine, except that when I run CPU-Z (v1.30), the memory FSB shows up at 100 Mhz, which is basically DDR200. To reinstate this, I get matching performance in both Sandra and Everest i.e. about 2900 MBps.
Okay now the memory I sport is Corsair XMS 512MB x2, model number being CMX512-3200C2PT. It's running in dual channel mode, with latencies 2-3-3-6. Now, regardless of what settings I try, the memory simply refuses to run at anything higher than DDR200.
I've tried setting the command rate to 2T, tried latencies 2.5-3-3-6, 2.5-3-3-8, and even 3-3-3-8 but DDR200 remains. I've even tried forcing the memory to run at DDR400 or DDR333 and upping the voltage to 2.7 from within the BIOS but nothing makes a difference. Oh and I've even flashed the BIOS to the latest 1014 revision.
An interesting point to note is that if I remove either ram stick, i.e. have only 512 MB in my system, then the memory runs correctly at 200 MHz (DDR400).
The only thing I can think of is that my 2 corsair sticks where not bought at the same time and hence aren't from the same batch. I picked one up almost a year ago, while the other came in sometime last month. From the information I've gathered, the older stick apparently uses BH-6 which the newer one has CH-6 chips, in spite of the fact the the memory is technically the exact model.
Are there any workarounds we know to make the memory in dual channel run correctly at DDR400? Before my A8V, the chips ran perfectly on my DFI nforce2 ultra.
