Phase change on P4's, how much more over air/water

[JNav89GT]

Never messed w/my prometia on any P4's. I would really like 4+Ghz and I have 2 3.0C's I can play with. They only seem to do about 3.6-3.7 on maze 3 frankenstien watercooling. Not great watercooling but ok. I can run about 100mhz more than air on my 2.4C if that is any clue as to effectiveness of my water setup. Maybe that is bad, but it's all I have for comparison. Do you think I have a good chance at 4.1-4.2ghz 24/7 stable on prometia b/c I would have to order INtel Kit for my Prometia and swap everything over

I had a 3.0C @ 4.1 benchstable @ 1.75V over here a few months ago

[ctgilles]

I ran my 2.8C on water 24/7 at {250x14} 3.51GHZ for about 2 months, anything above that would give lock up's or crashes.

Got a Prometeia lil over a month ago and now the same 2.8C is 24/7 at 3.92Ghz on 1.675vcore. and have booted an ran some benchmarks at 4.06Ghz but not stable, so that dont count in my book.

So for me the prommy got me a usable 410Mhz gain.

Well I had my P4 3.0C ABit IC7 @ 3.5ghz on air (no matter how much vcore i used i couldnt get more out of it.) Then i got myself a vapo pe and got it to 4ghz. thats 500mhz over

also i had a 2.4c @ 3.4on stock and got it to 3.8 on vapo

iim sure you will have your 3.0c's @ 3.9~4.1 on vapo and 4~4.2 on prom

One in a norwegian forum called snekker'n ran a 3Ghz@3.8 standard vcore with maze4 and peltier, he could do 3.6 without the pelt..
