I was just telling you what it was. I don't have very much experience with nForce boards, so I cannot verify whether it should be able to do at least 200 or not.Quote:

sorry, i wasn't trying to get huffy.... i was just pointing you to my edited post above your own... thanx for your info btw
Are we just talking Prime95? Does windows run fine? How about other benchmarks... how about games? If the only thing that screws up is Prime95, I say forget that and happily move on.Quote:

nah, it includes 3dmark and pi, both error out pretty quickly... but 198 is rock solid stable.. it befuddles me.
What voltages are you running? How are your 12v and 5v rails?Quote:

man ill be disapointed if the nf7 rev 2.0 wont even do 200fsb! some say it supports xp3200 but I doubt that since it was rated for 166fsb anyway. just that the new 2.0 revisions overclock very good, just like the tbred B's often did 2GHz, sometimes even more!

I was going thru this and all I saw was that your Vcore was at 1.65V.
That can be too low for overclocking. Maybe I missed something, but have u raised it?
Sorry if this was done.....
You're being ridiculous again, Tbird.Quote:

yeah, i have had the vcore all the way up to 1.85, it may give me a few extra minutes of stability in prime95 but it always errors out.

That includes your ram voltage; what is it running at?
Is that every test at that voltage, or just Prime - which, to beat a dead horse again, to me just isn't worth it.....Quote:

just in prime and pi, 3dmark will run fine at 1.675. as for the vrails, i think the 12v is around 11.45 5v are 4.85, i forget the other one... the rails aren't that true.. as for vdimm i think it is set at 2.6 but i have tried up to 2.8 and it still errors out...
12v rail is awfully low, 5v is kinda low too. what kind of a power supply is it? my first guess, based on that info alone, is that the psu isn't up to the challenge of overclocking that system. also, you could download SpeedFan if you don't already have it, and see if your voltages (core, 5v, 12v, and vdimm particularly) fluctuate a lot.Quote:

As thebove said your 12v and 5v rails are a bit low, that could hinder you overclock. Have you tried raising your vdimm higher than 2.8v? You should give everything a shot before giving up.Quote:

I don't think his mobo allows VDimms higher than 2.8v, which really sucks.Quote:

The 5v rail isn't too bad, but the 12v one is gettin out there. But it shouldn't be causing instability like that, I wouldn't think.
