Here's the set-up

NF7-S
XP2500 Barton Retail
Mushkin Green PC3200
Antec 350W PS

Timing: 7-3-3-2.5
Clock 180 Mhz
Multi locked at 11
cpu V = 1.675
Ram V = 2.6 V

I recently just tried to raise the clock to 182 Mhz, and it won't Post. This thing is rock stable at 180Mhz with the above settings with Prime running 17hrs plus (stopped it)

Thanks!

If you've got a new XP 2500, it's going to require at least 1.75v, if not more, to hit 11x200.

Yes, you need to increase your Vcore. I think mine's up to 1.75 or so @ 2.2GHz (I got a so-so one, it won't go past 2288).

What Rev is the NF7-S?, because most Rev 1's won't hit 180FSB. Other than that it may need more voltage

I've said it before and I'll say it again...

Why on earth would you even try an off the wall number like 182? What processor has a stock FSB speed of 182? What motherboard supports a 182 MHz FSB?

Immediately go from 166 to 200... afterall, why would you want to handicapp your PC3200 RAM by running it at 182 MHz?

Here... read this. Just a little something I threw together to get people on the right track and stop randomly trying things. You have to have SOME order at least.

you might have to raise your ram timings as well as the cpu voltage. also make sure spread spectrum is disabled

what are you talking about...it makes no difference! There is nothing magical about 166 or 200 just because these were chosen as the stock FSB speed for some chips. Just look to the Mobiles to see that the processor doesn't care [i[what[/i] FSB you run at, and the RAM only cares if you go above what it's capable of.

Oh, and to the OP:

Try 11-3-3-2.5 for your timings...the NF7-S does better with 11 than 7, believe it or not.

your agp/pci/hd will care though.. and your memory would be faster at 400 mhz fsb. I would definately jump from 166 to 200 and mess with the multipliers.

No? Explain why mine is completely unstable at 176-192 Mhz, but perfectly stable at 166, 200, 210, 217, 221, and 233.

Now, why in the world would you even try off-the-wall numbers like 210, 217, 221, or 233? Just jump all the way to 300, Jeff.:D

Where the hell have you been? I haven't see a post from you in... months.

And to answer your question...

210x11.5 = 2415 which was about my max overclock before upgrading my power supply...
217x2 = 432 ~ 433 = PC3500 RAM
221x10 = 2210 MHz with a 75% RAM divider made the RAM run at 166 MHz before when I only had PC2700 RAM
and 233x2 = 466 = PC4000 RAM which I was considering buying

That's because you haven't been around! I've been here, just not as much as I used to be. I still come nearly every day, though...

Wow, great advice - yes, for the record it is an NF7-S 2.0

I tried a 1.75 Vcore with a clock of 190. No dice on posting, and I had to run out the door. Next I'll just try a flat out 200 X 11 and then try the 11-3-3-2.5 timings.

Thanx

This is really weird.
It posted at 200*11 using the 11-3-3-2.5 timings with 1.75 V

But then this happened

NTOSKRNL.EXE missing or corrupt

It could not load windows! I set the clock back to 180 / 1.675V and kept the new memory timings.
It works normally with the old settings (except the timings).

What do I do? I thought I was home free once the thing posted.

my old barton.. factory unlocked, doesn't seem to run stable at 3200+ speeds at any voltage.. being cooled by a CoolerMaster HHC-001 heatsink too.

kinda sucks, but the CPU isn't one of those freaks that overclocks easily.

I just run it at 3000+ speeds which is no problem.

Check for agp/pci bus locks.... if they're unlocked, they'll be overclocking everything in your system including hard drive controllers which can corrupt your data.

Regarding the varying clock rates, some motherboards only have certain multiples available for the ratios to the PCI bus, so if you run at speeds other than the 'defaults', you may get instability. A good motherboard can run at any clock; i've run mine at all kinds of in-between numbers. You must just have a crappy mobo.... :) (kidding)

More voltage, and run your ram like this for the time being:

11-4-4-3

Either that or set your BIOS to optimal. I would try 1.80v BTW.
