I upgraded to a opty 170 and have achieved 3.0GHZ on air OC with 24hr prime stability, but I was able to finally get around to benchmarking it and noticed that my:

Memory Read / write bandwidth reported in Everrest is very slow, but in Sandra it shows up great.

54990
54991

The Memory Latency is just terrible?

54993

My Super Pi time is very slow:

54992

Here is some config information:

54994

I have tried adjusting memory timing, but wasnt' seeing any gains that would make up the lack of here. I have great stability. I have ran Prime on both cores with small fft's along with 3dmark overnight and no errors, memtest in windows and in dos still no errors. I just reinstalled the operating system and drivers.

I'm using 5/6 divider and thought that might be a problem, but changed it 1/1 and lowered the cpu to 10*260 and still the same, except for a little slower in Super Pi cause of the cpu frequency reduction.

Any suggestions or has someone seen this before? What about Bios Revisions?

okay, I found the problem. I had to update the bios.

Which bios are you now on? :stick:

I ended up using the latest bios on dfi's website. I ran some tests looking for instability, but all looks good.
