I'm having trouble raising the FSB

[ferrarifreak93]

My specs:
Athlon XP 1700+ revB 0302
Thermalright SK-7/Panaflo L1A/Arctic Silver 3
Abit NF7-S rev1.2 mobo
512mb hyperX pc3000 (1 stick, in dimm 3)

I'm having trouble in higher fsb settings. I have ran the cpu 12.5x168 = 2100 so I know the cpu can run at least that high. However, when I run the cpu 11x185 = 2035, the system won't post. My memory is certified for 185ddr speeds and I know the cpu can run to at leastt 2100, so what is the problem?

agp or pci prolly but im an idiot and have no idea but it would make me feel batter id some one would answer cause i would also like to know

I'm pretty sure the abit nf7-s rev1.2 has the agp/pci speed locked at 66/33 so that shouldn't be a problem

So what should I do? Raise vdd?

 

[ChampionAtTufshop]

you have to manually lock the agp in spec
pci i think is locked automatically

after that, what is the ram rated to (in terms of timings?)
try less aggressive timings

after that, raise vdimm first
(or try running ram at a lower percentage than 100%)
that would rule out the ram

that rev mobo almost always (afaik) has been able to hit 200mhz easily....
but yeh next try vdd

I figured it out. I think the ram was being automatically set by the bios to 2-3-3-7 which should work fine with my hyperx pc3000 ram which is rated at 2-2-2-6. For some reason though, it wouldn't work. I set the timing manually to 2-2-2-6 and I'm currently running the fsb at 185 w/ no problems (haven't tryed higher yet). Very weird...
