Ah! That *is* a very good question. You see I have found a loophole.
There is a bug in the NF7 that allows for higher peak bandwith with PC4000 that no one knows about
.
You see...using "Auto" RAM timings provides the same if not better bandwith than 2.5-3-4-11. Not only this but it OCs *much* MUCH better, as if it were using 3-4-4-11, but dosnt sacrifice *any* bandwith in the process.
"Auto" uses 3-4-4-10, thus that is what is listed in my signature.

I really appreciate the comments pplz.... I honestally hope that my results have helped someone here today. That is all that truly matters.

Beerhunter.... I love that W/C setup you have. I wish I had the effort and $$$ to W/C. Unfortunatly Im stuck with Thermalrights for now.

mcoleg what you are experiencing with Si-sandra is normal. When a CPU is tasked heavily things get really jerky. Thats totally normal.
I hope your OCing is going well. If you want some more info I would be glad to share it with you
Sentential, thank you, i apreciate it. glad to hear it's normal behavior for the cpu - thought i broke it by pushing it too far
.
had to take a break from nf7s system to deal with my pIV puter - finaly got a new m/b for it. used to have a pIV 2.4c on be7g, max fsb i could get was 179, which resulted in a 2.1GHz
. with ai7, runnung it at 268 fsb at 3.21 with one of those big quiet zalman heatsinks. i know it's nothing special but for that computer stability is paramaunt so i am pretty happy
for now
.
now i can get back to nf7...
i must say, ever since i got the new m/b (with blue ram slots) i was a bit confused. it doesn't behave quite as the older nf7s i had (black slots) dispite the fact they both are v2. this is what i noticed so far, if it's of any interest:
-memory controller and power circutry were redone somehow. to begin with, now memory isn't overvolting as much as it used to - at 2.9v it's only about 2.94-2.95v actual, before it was betwin 3.02-3.04v. on the old m/b to get to the higher fsb 1:1 with memory best bet for me was to set it to "by SPD" setting. now it's AUTO.
-vcore seems to flactuate less.
-south bridge is noticebly warmer.
-northbridge requires less voltage to get to higher fsb - i needed 1.7v for 241MHz, now it's only 1.5v.
-max fsb results are about what you have, Sentential, i would assume it's pretty typical? it's higher than on my old board, that's for sure... and everything is running pretty much stock right now, haven't had the time to play with it yet.
i think the comment about northbridge heating up has merrit, i was thinking about the same lines. my next step is to replace stock sink with one of these:
http://www.svc.com/zanoco.html or
http://www.svc.com/vansolcopvga.html
these are the ones i have lying around... vantec is cooper and has a fan on it, on the other hand zalman is much larger and i can just bolt a lil' fan to it... still thinking about which is better.
the major problem being, of course, not the cooler itself but the connection between the chip and the sink. stock one doesn't seat very tight.
i'll let you know if it would make any difference.
Sentential, i hope you don't mind me posting with all this in your thread; it just seems we are trying to achieve the same goal - high fsb, with pretty much identical hardware, as far as m/b and the cpu goes.
and be careful with the multimeters - that's how my last m/b wen't
.... all it needs is a swift kick in the a$$
