Looks like the Abit NF7-S Rev. 1.2 does over 200MHz FSB

[pelikan]

I'm posting this for those who want 200MHz fsb from an nforce2 board right out of the box. I don't have the Abit but in every account I've read so far people have gotten 200 - 210MHz fsb out of this board with no modifications. Being able to run the VDD up to 1.7V seems to be the trick.

vdd=chipset voltage correct?
what is stock chipset voltage? (1.5V?)

Awesome....good thing I bought one....oh the fun I'll have......😉

yeah stock is 1.5v

you can mod the epox i know so that you can get around 1.7v by lowering the resistance across one of the chips on the mobo....

but that's cool that you can do over 210 on the abit with no mod 🙂

What kind of ram? Im looking to hit 200mhz fsb w/ Samsung True PC2700.

😛 my 8rda does 210 stock out of the box

Im running my NF7-S v1.2 at 209.9
Corsair mem at 5.2.2 Cas 2
Xp2600 @ 2.3ghz

This MB ROCKS!

😛

once someone comes out with a NF2 board that unlocks CPU's with out modding them and has on board RAID then ill snag one 🙂 till then.......ill stay on my KD7-RAID

Cool! Bios adjustable vdd. I hear that may be coming in the next release of the 8RDA+.

Interestingly, my unmodded 8RDA+ runs vdd @ 1.58-1.60v according to mbm. Hmm. Do I have the wrong sensor set? Mbm doesn't allow me to change it. Lists it as "MBM fixed."

Anyway, I can post and boot winXP up to 210mhz fsb, but it locks up after a short blast of prime95. 205mhz fsb is the highest I can run stable, although I haven't fussed with memory timings much to see what fsb max I can run stable.

thats around what my vdd is as well, thats what its at when its unmodded

Thanks m1ke101.

Hey Assasin...........the NF7-S does that. You can manually change the multiplier through the bios without doing anything to the chip. Check out the review on the web......it uses a 5 bit frequency ID which give you the ability to change the multiplier on the latest CPUs.

All Nforce 2 boads do

my abit nf7-s rev1.1 DOESN'T RUN 200FSB!!!!

i think i'm gonna RMA it to get a rev 1.2

the AGP craps out @ 200FSB.. my video card starts to get all screwy...
i'm running it at 190fsb now..

Leave your APG locked at defualt.

If you have a 4x card .... 200/4 = 50 fsb ... so defualt (66fsb) should be fine...

My Radeon 9700pro has 8x so ... I still not pushing it at defualts.... 210/8 = 26.25 fsb

If your AGP is at defualt ... then its your memory or your CPU crapping out ...

(someone correct me if I'm wrong)

 

[Noid]

I forgot to account for DDR...

So ... it works like this ... for a 4x card ..

(200fsb / 4) x 2 = 100fsb AGP
((fsb) / (4xCard)) x (DDR) = AGP fsb

Im my case ... 8x card...

(204.6 fsb / 8) x 2 = 52.15 fsb AGP

So .. you could use extra FSB on a 4x card ... if it will handle it... otherwise I'd leave it at default.
