I would just like to know what the biggest OC you got on your chip?
and what is your 24/7 OC and what voltage?
Thanks

My 3.2E runs at 250 FSB 7x24 with P4C800-E-D and droop mod (made a huge difference in stability) Vcore at 1.4375

My E0 Prescott 3.0 does 4Ghz on air, 1.65V
Will try higher once I get it out of my p4gpl-x.

WOW, bud and you got the same MOBO I do. Is that your 24/7 speed your running?
and whats your ram divider?

P4 3.2E at 255 FSB with 1.425V running 24/7 on a P4C800-ED fully modded and watercooled.

Ain't got the rig anymore though.

Used to have my 2.4 northwood 12 capper up in the mid 4's on a 437watt tec cooled by a bong tower. Water was even still ambient. ;) Voltage was 1.95 24/7... Yeah I know, the chip was already voltage dependant heavily though.

My 3.2E does 250fsb 24/7, I can bench around 260fsb but thats about it.
p4c800-e deluxe motherboard (droop mod) and a big typhoon for cooling.
Measured the vcore with multimeter @ 1.44v
Ram is tccd and runs 1:1 (250mhz perfectly stable) :D

mine does 236 fsb, for 4.01ghz, with 1.4625 V. dead ass stable for anything, max ss is 4.25ghz, 250 fsb, 1.63 volts on water.

Not necessarily, there have been people running them at 5GHz (at least thats the largest ive seen) on phase and DIce/LN2 but i doubt anyone has those screenies around anymore and not many people aroundhere run phase on S478 for their 24/7 rig. My s478 Prescott's settings are in my sig but that will be changing midway through next week.

got my 3.2e D0 to 4.3 for bench and 4.2 24/7 on a unmodded p4p800se. On water.

Ok, so what volatage you running? and what revision CPU are you using?

Pure unadulterated :bs: :slapass:
If you ever had that you would have paraded it around for months, I remember when you joined here and EOC. :shakes:

Hi,
Sorry for the late reply. It used to be my 24/7 setup but it is currently offline as I use that CPU with my p4gpl-x right now, but should be back soon again, pushing it further.
Ram is 1:1

Before I went the way of the Sonoma I had an E0 3.0E which I used to run 24/7 at 3.82GHz on air in a droopmodded P4C800 Dlx. Can't remember the voltage though, I think it was around or just below 1.55v. The max unstable I got was ~4.1GHz.

I have an E0 celeron D 2.4 that i run at 3.77 on my non droop-modded p4c800ed @ 1.4 volts
Although i was running it at 4.14 (18x230) at 1.6 volts stable, but it just got too hot

Chong on EOCF could only get 4, and that was on LN2 :slap:

1.36volts running thorugh an E0 Stepping prescott at 3.75GHz 100% stable all day for D2OL. Load temps are at 50c running mediocre air.

I got my old 3.2e up around 3.8 on air, 1.55v. It was stable around the clock. Admittedly, I never really pushed it further than that, in those days I was scared of pushing a CPU to its redline...
edit: after gettin the dothan in, I'll never go back...
I used to run my 3.2E D0 24/7 at 4.1G 1.5v water cooled.
E0 3.0 @ 3.85 on air
4.2 Gig stock volts mach1
4.5 @ 1.5v on a mach 2.
on a ic7max 3, stock mobo.
ran like that for 6 motnhs before i sold the chip.
my 3.2D0 (blue system) run 3.92ghz 24/7 on air using that old cooler at 1.41Vcore. I can push it a lot more, posted at 4ghz but kinda hot, almost throttling. So I need better cooling but I'm willing to bet it can run way past 4ghz with proper cooling.

I use to have my 3.4E(es) at 4.7GHz on phase, with over 1.6V all mods on P4C800-E Deluxe. The kind of heatload was ridiculous, damn toasty things!

going by these results, there really wasnt a need for a new socket. dammn intel for 775 :slapass: , all they needed was to say that old boards with inadequate power regulation are incompatable. :mad:
For all this time i thought 775 was a dumb idea, but the oc's i've seen recently have lead me to beleive that it helps out a bit when the speeds are high. guess its just the new chips and chipsets after all.
to all above, nice results :toast:

Don't forget the 775 has 64bit and dual core support, something s478 will never have :nono:

well my s478 3.0E runs @ 3,83 Ghz 24/7 with 1,58v . But some of u guys have pushed it to 4ghz . I tryed to put it @ 4ghz 1,65v and it didnt boot up ..... CPU is watercooled

My 3.0E "d0" with 350w 16A on 12v runs on air (stock cooler) at 4180mhz@1,45v (with my 9600XT 670/350)

no way. according to the WR database, the record for a 3.4E is 48xxMhz :fact: thats as good as it gets for socket 478 it seems.

If you are a member of XR there is a for sale thread that says the Mobo was used to show that a Mach II could hold a 5GHz Precott. I own that mobo now and will post my results when i recieve it from the mail.
