System balance.

[arc@css]

My ram is 1600mhz, my mobo @ stock is 1600mhz. So should my cpu which is o/c to 3.5 (fsb I forget erm..155x) be a slight bottleneck? Looks as if I'd need to o/c a little higher to get absolute balance / good configuration.

Any help appreciated.

Your FSB should be 200Mhz to run syncronously. However, if the memory is running asyncronously then it will be fine.

(200 x 4) * 16 = PC3-12800

Haha, sorry just realized I got fsb mixed up with mghz on my cpu. Will check later and put the correct one in.

2328.16 up to 3492.24 according to core temp. Though why the multiplier reads 6 instead of 9, reads 9 in the bios.

vid seems lower too than I recall, was around 1.55 - now is 1.32

Check if Speedstep is enabled in BIOS. This lowers the multiplier automatically if the system is idle. As soon as the system is under load, it reverts back to 9. You can disable it if you choose.

Is it better or potentially more stable if you disable it. Kind of giving it an easier time?

In very rare cases you can hit a frequency hole - but it's not likely.

Eg it will work fine at stock 200 x 6 and 200x9, and overclocked to 400x9, but for some reason it just won't agree with 400x6. The chances of this happening are really very low.

Personally I disable cool'n'quiet (AMD's version of speedstep) while doing the overclocking, just because it's easier to see the frequency you're actually running at a glance. Stress test it, then enable it. It it becomes unstable, it's causing a problem otherwise leave it.

Cheers, really appreciate the help there.

I tend to have it disabled, just makes it easier to check how your overclocks doing. Leaving it on basically is a power saving function, think theres a way to disable it from the power options in the control panel, but not 100% sure on that
