quick P4 Questions

[lodog00]

I have a 1.8A that reads as a "2.4B" in the bios when set to 133 fsb. I'm fairly new to the overclocking thing, but am aware of intel's underclocking practice.

Now, the question is, do I have an underclocked 2.4B, or do all 1.8As read as a 2.4B at 133fsb? It's read as a 1.8A in wcpuid, so I assume the latter?

The proc currently is at 2.52Ghz/420 DDR (fsb 140, 2:3) cas 2 at the stock 1.5v. Absolutely stable using Sandra's Burn In Wizard (99 times, CPU and memory) and Prime95 torture test (8+ hours). I still have yet to run PCMark and 3DMark though.

and one more thing, the pack date is 6/9/02 Phillipines, and it's an SL63X chip if I read the intel website right. Not the vaunted SL68Q, and probably won't get near 3Ghz...but does anyone know how far this thing might go, below 1.7v? I just got it a few days ago and am still playing with it...

I'm satisfied at the current settings, and may knock it to down 2.4Ghz for maximum 100% stability, but just curious how far it can go (stable that is). Stability is more important than max performance...


update:

Now here's a strange thing. Ran Prime for 15 minutes at the above, and it stopped due to a hardware error. Ran it again, and it went strong about 6 and a half ours....then the system froze sometime between then and 8 hours (I was asleep!). Is my chip unstable, or is it just Windows or my PSU that are a little wonky? Sandra still passes every time.

I also have some random stability issues, with the computer rebooting and programs crashing, despite being able to torture the system and burning it in. I suspect that could be caused by Windows though? Should I move on to WinXP?

That's a nice OC there, so far. No need to knock it down to 2.4GHz as I would consider 8+ hours in Prime95 to be 100% stable Only way to know how high it'll go is to keep OC'ing 'till you find out But I'd say that if you're hitting 2.52 at default voltage, that you should probably be able to hit 2.8GHz+ stable. Just make sure you reduce the mem ratio before you start increasing the FSB any further, as I doubt that RAM will be able to go very much higher than DDR420 (nice RAM, btw, what kind is it).

Believe it or not, the RAM is Corsair XMS 3200 c2.5 It's the rev 2.1 (according to the label!) with the Winbond Chips, and people say they've gotten them to OC well. Looks like they're right.... I can't get cas 2-5-2-2 at anything higher than fsb 180, but it will run cas 2-6-3-3 at VERY high speeds (210 fsb passes Sandra burn in with flying colors EVERY time.)

I'm waiting for my OCsystem 420 watt PSU to come in before I do any really high OCs...Perhaps I should've bought a 550watt Enermax, Antec, or TTGI in hindsight, but you can't beat the current sale price ($45!)

Nice RAM! 420w should be plenty
