You went from a 2.66 MHz CPU to a 2.93 MHz CPU. I may be wrong, but I see nothing wrong with the benchmark results. Adding cores doesn't necessarily improve the scores, but it allows you to run more tasks simultaneously.
I do plan on overclocking eventually,
but don't see a need right now.
I amagine I could easily get 3.4 for daily use with little voltage increase.
I'm not having any problems,
Memtest86 (dos version) did 2 passes np.
Prime95 passed 4 hours easy.
im getting 47c max temp on core 1, the others seem to be 3c lower. (maybe the paste didn't get it entirely.... I use small amounts...)
This is with my modded zalman cooler.
It is running nice as well,
but I was concerned because I was expecting a passmark cpu mark in the 4000 range. But I only scored 2000'ish.
My old 6750 @3.4 would rock close to 1800
From your 3dmark06 scores though It seems that the cpu is performing just fine.....
Maybe it's an OS re-install or new hdd that will fix passmark score.......
I bought 2x WD7501AALS WD Black 750gbs
I plan on partitioning them in halfs and running a dynamic disk raid 1 and 0 setup.
I might keep my 250 If I cant find a replacement key for windows 7 rc.....
Should I be concerned about my 600w psu by Ultra...?
Newegg recomends 640w for a 3x drive setup like mine.
While it ain't a tier 1 PSU, it should be fine. As I stated before, your system overclocked to 4 GHz requires 428W. If you really want to overclock, do it in steps and back-out when the system no longer is stable or it runs too hot. Stable for me means no system crash at all. If a system crashes one a month, then it isn't stable.
