Lavalys Everest Memory Performance

Website: Lavalys



With the latest BIOS we managed to get the EVGA nForce 750i FTW down to 4-3-3-10-1T memory timings. 3-3-3-9T gave us sporadic blue screens with our 2GB kit of OCZ FlexXLC PC2-9200 which uses the popular Micron-D9 memory chips. Even though the 7-series of Nvidia nForce chipsets see the greatest benefits from 1T memory timing, which we were able to run, in Everest the nForce 750i SLI performs pretty mediocre at best. While the read and write performance are quite good, the copy performance is severely lacking. However, this looks to be a "feature" of the Nvidia chipsets though as the nForce 780i SLI mirrors this.

The latency also seems to have taken a massive hit, even though we're running pretty tight memory timings. In contrast the XFX nForce 780i SLI which is based around the Nvidia reference design has the lowest latency we've seen and a much better read performance, even though it was only set marginally faster at 3-3-3-9-1T with the exact same memory used.

Sisoft Sandra echos the Everest results - the EVGA nForce 750i SLI FTW comes out the bottom of the table in raw memory performance and almost the highest in the latency stakes. However this is just a guideline - what about the real world?...
