Greetings,
Just got working ram for my system so was able to start actually looking into overclocking these proper. My last sticks failed regardless of timings so left them on the lowest divider and as thus missed this issue initially. However, the timings in the BIOS for 667mhz is invalid to the actual settings applied. Running at full stock settings aside from the Ram Divider yield the following results:
Dividers (In-Bios) and Results (Out-of-Bios):
400mhz(800mhz) = 400mhz
533mhz(1066mhz) = 533mhz / 3:8
667mhz(1333mhz) = 533mhz / 3:8
800mhz(1600mhz) = 800mhz
Bios affected: 1.10 + 1.20
800mhz works perfectly fine as do 400/533 without issues and no fallback at all. However, selecting the 667mhz divider results in the same divider and timing as 533mhz. This does not match up with what the bios is showing in any form and is likely evident of a bug within the Bios GUI itself. It shows the divider fine visually in the bios but 667mhz outside the bios is a completely different result from within Memtest x86+ and CPU-Z (which show 533mhz). Is there any bios that has yet to be posted with this bug fixed at all? Cannot seem to find one beyond 1.20...
Relevant Specs:
CPU: AMD Opteron 1389 RevC2 @ 2.9ghz
RAM: 2x 4gb Samsung MV-3V4G3/US @ 1600mhz (800mhz)
