No chance to make 2:3(266) or 5:8(333) to work? On some boards these (especially 5:8) seem much easier than other dividers.

2:3 posts but freezes after usb init, 5:8 works but requires 7-7-6. I will re-run with another cpu and fresh windows installation, hopefully will make runs with both a.m. dividers.

Try POSTing 2:3 either at 570-580 or at 649+ FSB.

Actually s266 2:3 direct boot @643 was doable before repair (SB swap) - I think I should just try different cpu, this one had issues starting from 625mhz on core0 and it is hard to tell cpu limit from potential issues with the board.

Excellent work, Nikolay! )

Great work. You can more))))

Very nice!

Nice mem wow

I'm amazed that you can get any form of FSB reliability above 600 with Wolfdale on single stage. It seems that no matter what I do, the behavior is only stable for me when the CPU is on LN2.

Preach, I never could get the REX to behave nicely. Well I managed to get 634 2:3 32M working nice with PSC, but it seems harder with hypers and never consistent.

Wow ! Very nice ! Strong ! Big grats !

@TaPaKaH what temps does your single stage do? On my single stage I can do 615mhz on most of my wolfdale chips but that is the limit of my p5e3

Fake clock in cpuz, it is strap 400 2:3 being detected like this.

For me, it is more about cpu/nb skews (>600 should be smth like 300/0, >625 300/100, >640 400/100) and gtl settings. This one was binned out of 4 samples, 3 are consistent @625mhz, 1 is failing even at 600. 

Great result!

Good stuff with that one!
