P4 overclocking?

[joburnet]

I was wondering if anyone has actually gotten hold of a P4 plus a motherboard and at least attempted overclocking. I doubt it, prolly have to wait a few more weeks at least before we see this but I thought i'd ask.

 

[ravedave]

My 2 cents:

HAHAHAHAHAHAHAHAHA

1) yeah right noone has a P4 + mobo except maybe anand
2) 1st round processors are usually crappy for O/Cing

 

[joburnet]

ok then, what are your predictions for overclocking. The P4 is a huge hot chip, but they do already have 2ghz P4's running.

 

[AdamK47]

I'd wait for the .13 micron Pentium 4 CPUs to come out before thinking about overclocking. They will be a whole lot cheaper and have a more headroom to overclock than the .18 P4s.

If I'm not wrong, they require a heatsink with at least a mass of 500g?!!?? What are your chances of overclocking and not frying an egg on top of it?

 

[Sunny129]

i really dont think mass has much to do with heat dispersal. after, two heatsinks identical in every way except material will perform differently. one could be aluminum and another of the exact same shape and design could be made of copper, and the copper heatsink will disperse the heat better than the aluminum one due to the thermal properties of the two metals. even if the surface in contact and wings around the top and edges are the same on both, the copper will yield lower temperatures. nevertheless, companies will find a way to design smaller and more efficient heatsinks for the P4 once it hits the market.

When it comes to performance I am unsure what you THINK you will get with the P4 but I am sure of one thing...you will be disappointed unless you use intel based benchmark tests, and ignore real world apps.

You could still be forgiven though!

Take a look at this chart

We're going to need some innovation once CPUs start giving more heat. Not simply straight out methods like a 38cfm Delta fan. Unless of course, water cooling becomes more popular. We are either going to be running CPUs a lot hotter than we are used to or will wind up paying a lot more for air cooling solutions.

 

[jinsonxu]

By the way, the extra force is for proper heat dispersal. There's a reason why the clips are so hard to force down for the good socket a coolers.

By the way, Welcome to Anandtech Sunny!

I see your ICQ mail worked.
Could you authorise me in ICQ?

 

[Sunny129]

true...they are pretty tough to clip onto a socket, so there must be a reason for it, and its probably to help with heat dispersal.

PS - thanks for the welcome and its good to see you again jinsonxu

I know of a few people who have benchmarked Willamettes recently. It is apparently more readily available to testers than, say, the AMD760 chipset was.



> 2) 1st round processors are usually crappy for O/Cing

At least one of the boards out there for testers have options to change the chipset to cpu communications frequency. It'll be interesting to see how well it overclocks, as the chipset to cpu comm freq is pretty low (100MHz), but the data rate is 75% higher than anything we've seen before in the x86 market. So, will it be constrained by the high data rate, or will it be easy due to the low clock??

hey ravedave, check this out

Once you get to the bios screen, over clocking is very easy with the P4. The board allows you to set the clock speed to 1.3 GHz, 1.4 GHz, 1.5 GHz or 1.6 GHz and was stable at all benchmarks at 1.6 GHz.

You need a shoehorn to get your foot out of your mouth?

 

[AdamK47]

Those are with engineering chips though. They have the multiplier lock disabled.

Am I the only one not expecting much o/c'ing on the QDR FSB???.. seeing how much trouble it is on DDR

P4 overclocking
Tom has overclocked the 1.5 P4 to 1.7ish
Very stable system, but way too much $$$

 

[her209]

one question, what do you need to run at 1.7ghz?

 

[Bignate603]

lol, you wouldn't NEED the speed, but wouldn't you WANT the speed.

 

[atomicbomberman]

it doesn't

too much heat.. maybe when the .13 micron die version comes out.
