Just spent the day with a new 2.4A Prescott Pentium 4 (bought it from NewEgg) and an Asus P4C800-E using a stock Koolance Exos system....

The CPU was rock solid at 3.69GHz with the voltage pushed to 1.62. It was completely stable at 3.3GHz at default vCore.
 
On this P4C800, it is running very cool. Showing 96F at idle at 110F under load at 1.55V. The Koolance temperature probe (albeit not located well at all) is reading 90F. Feeling the back of the board and areas around the CPU while under load, 110F is not far off. It certainly is not baking and does not feel "dangerous" like some of the others I have experienced.
 
Doing some more playing with our 2.4A Prescott this morning...

Out of the box, with stock air cooling, stock TIM, stock voltage, it is running a very solid 3.3GHz. ( I tried but just could not get it to an even 1GHz OC at 3.4. :( ) With two instances of Prime95 running, the temperature is staying about 125F according to Asus Temp Probe.

I am going to let it run for 8 or 10 hours and see if it stays solid, but it looks like with the right motherboard, this could very well be the next enthusiast CPU to have especially considering you can take some decent DDR333 and run 184MHZ sync bus out of the retail box.
 
what kind of ram are you using? and what cpu:dram clock ratio if you don't mind me asking?
 
I have used 512MB and 256MB sticks of PC3500 HyperX and 256MB sticks of XMS3200LL from Corsair. 1:1. Tested with both SPD settings and tweaked settings.
 
Any benchies? Intel usually needs insanely high FSB to perform...but then again the extra cache could make it scale better too.
 
I am going to put together a quick article and share with everyone. Took some basic sandra and 3DMark01 benchmarks.

From 15500 stock to 20200 oced. Not bad for a $150 chippy, and I think they price will be going down....
 
did you disable the dynamic voltage thing? if you didn't, try doing that to raise the scores (some)
 
Kyle,...thats pretty close to what I got...I also found that the PAT/GAT would become disabled on the Abit IS7-E2 at any fsb over 190...or at any N/B strap setting above 533...I think thats an Abit thing though...

JC :D

Agreed... very nice overclock on that chip!!! Its good to see some of these new Intel chips doing well after that initial batch heating up so much.
 
I wonder how the Mobile Bartons oc'd compare to this 2.4A oc'd. Especially when people get their hands on that XP-M 2800+ :D. We should have a thread comparing benchies from oc'd Mobile Bartons and lower-speed Prescotts.

I hate Intel's naming system. Dammit there's already a 2.4A which has the Northwood-A core. They should just name it the 2.4E, even though it only has a 133MHz FSB.

damn nice OCing.
I'd like to see how one of these runs under the evap of the new VapoLS....I suspect a direct die cascade would get some really interesting results.

I am considering a trip over to the dark side when I get my latest phase change cooling system finished (dual compressor classic cascade - it should be able to run around -100C). Until then, I will continue to work with the temps my single stage R22 system can produce:

:D
 
holy crap... i have to start making a phase change setup for myself ASAP!

maybe i could convince my parents that i'm getting a head start on science fair for next year... ;) then they'd pay for [some] of it...

maybe you could lend it to Frg for overclocking the prescott... see what it could do:eek:
 
No Hyper-Threading? That sucks. Maybe AMD can overtake the P4 in video/audio encoding now :D
