DDR400 @ 200Mhz = poor performance?

[SpaceRanger]

Hello folks,

I just got done installing the EPoX 8KDA3J (Nforce 3 250Gb) motherboard for my Socket 754 Athlon 64 3400+ (old Mobo bit the dust).

I'm benchmarking my memory timing and configuration, and I'm getting what seems to be horrid performance.

I'm not overclocking the motherboard or memory at all. For my memory timings, I have them running at CL2-2-2-5 (at least what I believe to be that), and in the POST of the machine, it says that I'm using DDR400 @ 200Mhz, 1T, 2-2-2-5.

I run Sandra Memory Benchmarking, and get the following:

Sandra Bench Results (I'd include the image, but it seems you can't here)

Compared to the results from an Nf3 150Gb board, I'm over 2000 points slower in performance.

Anyone work with this motherboard and have an idea as to what I am doing wrong?

Thank you.

Rob

no. Your scores are absolutely perfect.

Remember socket 754 A64's run in single memory channel mode.

You are geting 94% memory bandwith use, and that's excelent.

Intel systems rarely use more than 60% of their overall memory bandwith available.

Thank you Aenslead. One thing though, why did the Nf3 150Gb graph show a 5.4K reading??

Because it was a skt939 config. Besides, sometimes Sisoftware uses many speculative numbers, and I do not doubt this was one of those cases.

Cheers.
