Well, right now AMD is doing a pretty good job keeping the temperatures down. At least, better than Intel with their Prescott chips. :P I can't diss the Northwoods though, they're pretty damn cool. (No pun)

yeah, the prescotts run hot, really hot! :oops: like as hot as my face!

plus it's scary to try and push one of those, plus since the prescotts are 775 pins, they are scary to insert also! It's really easy to bend the pins!

yeah. I'm actually scared to touch friends pc's when they need help doing stuff like upgrading the cpu.

If you think amd's run hot, look at the mid to high end p4 prescotts. They've been called mini space heaters. The last great Intel chip, is the pentium m. gimme gimme gimme! That and the old northwoods. friend of mine named dippy (big amd fan, heavy in to oc'ing his rig). He has an athlon xp-m (2600+ i think...) at 2.5 to 2.6 standard but has been successful at taking it to just over 3.0 - this is on air. Gotta love those slks :)
I've seen good overclocks from a celeron-d but presscott architechture is taking a beating from a64 these days.

pentium M's are insane u can get 2.7 at least from a 2.0 pentium M with the tiny heatsink which is smaller than some north brige heatsinks now, if u got a zalman 7700 or a themraltake tower112 on that mofo, DAYM!

Northwoods still rule, if you have decent cooling. My own experience:

2.8C at 4.0 water cooled
3.2C at 4.2 water cooled
3.2C at 4.56 single stage phase change
3.4C at 4.8 dual stage phase change

Btw, a 4.8 GHz Northwood-C easily outperforms an FX55 clocked at 3.5 GHz. (as far as it goes with the same cooling unit)

wow.

i personaly have good experience with ocing pentium 3 chips. so far i haave 1 600mhx p3 at 1.1ghx and a 800mhz p3 at 1.5

Ok guys lets face it... He's right about Intel with the whole heat situation. but i have had alot of luck with amd's as long as you control the heat these proc's fly. Im also surprised nobody mentioned a lower end proccessor afterall we are talking about overclocking here which is the secret art of saving money. i curently run a barton 2500 with the multiplier set at 12.5 and the mhz at 180 which translates into 2250mhz. air colled with a coolermaster aero 7+. 45c at full cpu load. now thats bang for the buck...

A little news that may not be a shock, but Intel may not be much of an overclocking CPU for long.

In the past, they've always fused their units with a pretty wide buffer. Celerons of yesterday had huge buffers from what they were tested at from what they were actually set at. It narrowed down a bit with the Socket T prescotts, but it's getting smaller and smaller.

The buffer range was just used for warranty reasons. Like, "we've tested this CPU to run at 3.0, it's passed with flying colors at 3.0, but we're going to make really sure and fuse it at 2.6Ghz". This has made some customers made (OEM's) and they're backing off on this buffer a bit, and both parties are just losing money here and there due to these huge buffers. With Intel and leaving out the OEM's, people count on this OC factor (don't we all!?) and go one step down, then ratchet it up to what we really wanted (get a 2.8, run it at 3.2). So many folks have caught on to this that a bean counter or two took notice. People are buying 560J's instead of the 570J's...the horror! If it's not obvious, this is a $400 gap in retail pricing and that can add up as a noticable loss.

Well, like I said, this has been removed lately. So you may want to start shifting gears a bit on easy OC's out of the box. It may not be totally gone with the current Socket-T's, but expect the next steppings (after E0)to have a fairly narrow buffer. A 3.8 may just push 4.0 :p

AMD will more than likely follow this as well. Hogwash? They locked their multipliers too, ya know. And it's hardly ever about the customer, as much as it is making the stockholders money.

Newer chips generally don't overclock well compared to some of their older brethren:

My best: (all on AIR, btw)

P4 1.6A to 2.66Ghz

P3 700e to 1001Mhz

Celeron 366A to 550Mhz

These also happen to be some of thebest rated chips for o/c of all time...

Sounds very solid, but i'v decided to go with 3500+ so a 939 socket, beautiful !


I got a 3200+ 90nm winchester to 2770mhz so far, I am gonna raise the vcore tonight and see if I can get 2.8ghz out of her. :twisted:

How much cooling would be involved with a 2.8 prescott to like 4 ghz? Would water cooling work fine or would I have to bump up to phase change or something like that.

water might do it but I wouldn't put any money on that bet. Phase cooling would have a better shot at getting up there, alot still depends on the chip as well though.

yea I've got some bills and a sears card to pay off before I consider OC'ing. I do sence water cooling in the near future.

You're asking for a 1,200Mhz OC which is a 43% over stock. That's asking for a LOT on the hardware alone. Not even phase changing may get you there. With a 550, I got a 935Mhz increase and was more than happy with that 27.5% increase.

There's just so much the silicon can physically take before it reaches it's limits...even theoretically, that's a bit of a high standard to reach for.

Don't let me hold you back though. Give it a shot...you just may pull it off.

If you really want to OC and AMD64, get a amd 64 mobile. Because of thier lower power draw and default vcore, you have a lot more play room to up the vcore, and thus, the clock speed.

Yeah, but too bad they require the non standard HSFs. Some work, but most don't.
