With all the hype surrounding DDR2 and Socket M2 I have been wondering how much a dual core K8 likes bandwidth/latency. I've been encoding a lot of video lately with Staxrip/Divx6.1.1, so I went about encoding three times on the same job with different RAM settings.
Job 1: 2.5GHz, 250MHz RAM, 3-4-3-8 (PC4000 2GB DDR1)
1st pass=79 fps, 2nd pass=81 fps
Job 2: 2.5GHz, 195MHz RAM, 3-4-3-8
1st pass=74 fps , 2nd pass=76 fps
Job 3: 2.5GHz, 195MHz RAM, 2.5-3-2-8
1st pass= 77fps, 2nd pass= 77fps
All passes run with a minimum of background apps running. Identical OS environments. There's definitely a combination of benefit between lower latency and more bandwidth. The higher latency of the RAM is less damaging with a high RAM clock. The delta here though isn't exactly mind-blowing.
