I am experiencing extremely low memory perfomance. Configuration:
Epox 8rda3+ Nforce2 Ultra400 mainboard, Barton 2500+, 2x512 PQI PC 3200 DDR,
Radeon 9600pro, S-ATA Seagate 7200.7.
My memory read rate is as low as 1300 MB/sec (calculated in Everest Home edition), games also run very slow. (for example, on my machine GTA San Andreas is almost unplayable).
Memory timings are 2.5-3-3-7, memory works synchronous with FSB at 166 MHz DDR.
Latest Nforce drivers are also installed, OS is WIN XPpro+SP2. I tried using different memory modules but to no effect. Memory modules are in two same coloured sockets for dual channel to take effect. I tried using just one module for troubleshoting but performance remained the same. To my knowledge memory bandwidth should be at least 2500 MB/sec. I'm slowly running out of ideas, i tried virtually everything but my memory still runs like a SDR, not DDR. Big thanks in advance to everyone who even consider to help.

:confused:

Youre right it should be way more. I got 2680 with 2.5-4-4-8 (intel 2.2 @ 2.4, DDR433 at 420 single channel) in Everest. But if its synced at 166, youre running at DDR 333 speeds. What is the command rate set at (T)? But I dont think the diff from 1T to 2T would be 50%

Can you drop CAS to 2.0? When I run my mem at 333 instead of 400 I was able to get 2-2-2-4 (5? cant remember off hand).

Wish I could be of more help besides confirming something is wrong.
