First time OCing P4 2.8 Northwood - Page 2

post #11 of 25
well I took it up from 133 to 147 or so without any stability problems. After that Prime starts to find errors. That's without doing anything to the voltage, wich I won't modify until I get good cooling. I'm with the stock cooler ATM

updating on that, still at 147, with 37 C idle, 47 C Max load (as reported by Asus Probe II). I need some better mem-sticks too

Your temps seem ok (55 is the limit for Northwoods IIRC), but yes, you definatly need some better RAM.
post #14 of 25
55? You sure? The specs I DL-ed from Intel say 75 MAX temp suported. Celsius offcourse.

It's weird, anyway I don't plan on going higher untill I get better cooling and better memory. So far I've just tried the waters sort of speak.

I also have the same 2.8 Northwood, i could never get it to run stable over 3.4, but I was also using a $20 ECS l4vx2a mobo and pc2100 ram, man that thing sucked The CPU-Z is in my profile. I had to use a low bus speed, it wouldn't run stable any higher. I haven't messed with my new setup much yet, running @ 3.4 with reasonable temps.

If you have some mula check out adeolivers 2.4c 30 capper in the for sale section I think he's asking for $80 for it. 2.4c's are awesome overclockers, and the the 30 cappers are even better. bandwidth is a big deal in overclocking (fsb) prolly more so than raw Mhz imho

I haven't really looked into 800mhz bus processors, my new board supports them. So after I get tired of this 2.8, I'll prolly upgrade. Just playing around right now, this is only my second overclock, which I hope to be better than the first.

So I decided my compy was getting a little slow. I wandered on over here and read through the Intel overclocking guide and numerous other things on here. Very informative, cool stuff.

I'm having a little trouble though. Compy I'm overclocking is the one in my sig. So this is pretty much where I'm at right now:



I can't really seem to get much higher. I'm assuming it's capable of going faster though, I read about a few setups basically identical to mine that were running 3.8. Any suggestions? Main thing I'm confused about is RAM timings. I tried various settings but none of them seem to make any difference when I try upping the FSB. I've hit the wall with vcore so the next step is to adjust RAM timings to allow a faster stable speed with the FSB, correct?


Anyways, any help would be awesome.
I was wondering if anyone could tell me why my multiplier is locked at 21x, I just noticed that with the same processor, you are able to run 14x for the multi.

It's not the same revision processor.
Mine is 21x too.
I managed to get mine around 3.4 too but I got some errors in Prime95 so I took it back a notch. After I change my mem's and add some decent cooling (I'm on stock right now) I'll take it a bit higher.

PS: you can rarely find a CPU with the multiplier unblocked... usualy only the Engineering samples are unlocked, and I don't know a single place where you can buy them.

Ah, I believe i'm going to start looking into a different processor, think I have hit the limit with what i have. I've been thinking about a 2.8 800 fsb northy with ht, anyone got ideas what revisions and steppings i should be looking for?


I also saw this go through ebay <a href="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6881205740&rd=1&sspage name=STRK%3AMEWA%3AIT&rd=1">3.2ghz ht, engineering sample?<a/> wasn't sure about it so i didn't bid, lol.
