I agree with what most people here have said. You've upgraded a bit unevenly. You've dumped a rollys royce engine into a honda transmission.
Slightly off the topic - someone here mentioned FEAR Combat being free and online for multiplayer. Have you guys tried it out? What's the catch. Why would they provide a free online game at full version? Thanks. Dont want to get too much off the topic.
afaik socket 754 procs are all single channel, regardless of what the mobo "supports". Only w/ 939/940 (and newer) did amd have the dual channel controller in the proc that I know of.
look here on wikipedia.
Socket 754 is a budget-minded socket, for use with AMD Athlon 64 or Sempron processors. It differs from Socket 939 in several areas:
* support for a single channel memory controller (64-bits wide) with maximum of 3 DIMMs (no dual channel support)
* lower HyperTransport speed (800 MHz Bi-Directional, 16 bit data path, up and downstream)
* lower effective data bandwidth (9.6 GB/s)
* lower motherboard manufacturing costs
sounds alot like frame tearing, which can be fixed by turning on vsynch (vertical synchronization) in the driver settings. The wierdness is that if it truly is a pre-rendered "video" and not a movie rendered in real-time in the game engine then the vsynch should not affect it. Play w/ that setting though and see.when they pan quickly across the city in the into preview, the video seems to skip a beat as it pans, appearing to be jumping from frame to frame, and my eye can actually see that little jump. When the movements are slower, you cannot notice it that much.
