P45, E8600 & CPU PLL help?

This is as high FSB I could get stable for 4 hrs prime95 blend. The board has so many voltage controls you could spend all year on it and just barely get to experiment with them all...

That's pretty impressive , max stable i could get was E8500 - 4,310 7.5x575@2B 1,150 5-5-5-20

I think it might be the ram I have that could be causing issues. I have two different sets of DDR2 to use but there is not much difference between them. A lot of the dividers on this board only work with low FSB except 2.00A (266Mhz strap) thats with the ram I have. I can't get the board to boot at stock FSB with any of the 2.00 dividers except 2.00A. I've put my E7200 on the board now & moved the E8600 to my trusty P5E board.

Your right memory sub system is the restraining factor. CPU & FSB feel solid and i'm sure can be pushed further. My crucial ballistix 8500 seem about maxed out at 1150Mhz. Have tried tweaking most of the settings. Latest that gave me a little extra stability was Clock Skew Control -100 channel A & +100 Channel B seemed to give a bit extra in that elusive attempt to get to 1200Mhz

That's odd , no such issues here I'm using B & D mainly, not to many issues.

Yeah, clock skew controls are something I would use as a last resort but even fiddling with this does'nt help. I have Corsair & Patriot DDR2 and both behave the same no matter what divider I use.

Not sure what you mean by "B & D" ?? ( I mean I do know what B & D is but not in the sense of computers...)

Sorry straps as in A=266 B=333 C=400 D=800 FSB Base (see System Memory Multiplier)
