I recently finished the build on my A64 3500+ with an A8V MB and Corsair Twin1024-3200XL memory. Flashed the bios to the newest revision (1006). Upon boot with all settings on Auto, the memory shows in CPU-Z as 2-2-3-5 latency running at CPU/11 (FSBRAM). Now this memory is supposed to run at 2-2-2-5 timings. If I go into the bios and set the memory to Limit instead of auto, I can force 1:1 at which point, the 2-2-2-5 timings appear and the FSBram changes to CPU/22. Now if I do my math right, that means the memory is running at 100mhz...for dual data rate, 200mhz...which is half what I would expect PC400 RAM to run at. If I switch the timing to auto or 2:1 the CPU/11 comes back, but timings go to 2-2-3-5 again, even if I tell the bios to run the 3 timing at 2 manually. Moreover, at Auto and 2:1, Memtest doesn't get much beyond 100% before it detects an error. Thoughts? Suggestions? Explanation as to what the 1:1 and 2:1 really mean in an A64 board with hypertransport (I can find lots of mentions that 1:1 is ideal in a P4 system with a 800mhz fsb...but not much written on A64s).
