Very interesting.

Looks like the often slated overclocking softwares have a purpose after all especially ClockGen

DFI will likely have different FSB straps than ASUS.

Have you done any of your own testing using Clockgen? I'm thinking of downloading it and wonder if its any good

This newly discovered info also shows why 410Mhz FSB is more stable than 390Mhz for a lot of people.

@ Joeking78. I am going to wait for my P5B (gets here tomorrow) before I test thing. However, there are plenty of people who have run this on their system with the exact same results.

From my interpretation, 400Mhz FSB with the default multiplier and as high of a memory speed as possible will be the best performance for people who can't go higher than 500Mhz FSB. For people with X6800 and QX6700 the multiplier part is null, because the NB detects any multiplier as default.

Edit: There is a big push to get the BIOS engineering to give the NB strap control over to the end user. That would allow up to define where the NB changes latencies.

So what are you saying...

400x7 = better than 434x7

Or are you saying to set 400x7 in BIOS and go into ClockGen and set 434x7.

It also shows why the eVGA 680i has so many 'dead spots' in its FSB range.

EVGA 680i works entirely different than P965 / 975X

@ Lightsource: Yes, 400 x 7 is better than 437 x 7. Just do some Super Pi tests with it. Clockgen will be inherently less stable because you are working on the lower strap, but that is the best way to go to get 437Mhz (although it seems there is no chance at getting more than 10-15Mhz FSB from clockgen).

All right, what about in F@H? Faster WU's?

Very interesting topic, good find.

I ahve one small kinda off topic question. I never realized before hand that dropping to a lower multiplier will OC the northbridge. This makes me nervous as I was going to go form a multiplier of 9 to 8, and run maybe 430 x 8 as this will get me ddr2-1075 which I can do at 4-4-4-12. Would this push my Northbridge too far, would I need better cooling? I know its off topic, but were talking about the northbrige anyways, so whay not.
