HOLY HOT S*** - 4.8ghz P4 640 w/ WC

[Sneaky]

to make a long story short, crimedog (over @ OCForums) is lending me his P4 640 and i'm sending him my 660 for some sub-zero testing, and anyways, by nature, i bust out AI Booster and start clocking the 640 to see how well it does...

lets just say i almost shat my pants when i got this:

thats watercooled with a Storm G5 and 1.55v :slobber: :slobber: :slobber: :slobber: :slobber: :slobber:

crimedog... i hope you know that you have one hell of a 640 right there... i don't know if i wanna keep this or my 660 ROFL :eek:

[afireinside]

stable?

[Sneaky]

stable enough to get a CPUz verification... but it took a crap when i tried opening up superpi

[Hound]

lol, whats the defualt volts for that cpu...i live on amd's :p:

if its around the 1.3v give that kid more, 1.9v is safe on water isnt it? :p:

but, nice clocking, hf

[`SippY]

temps?

[Sneaky]

default voltage is 1.4v, and i tried 1.6 (dont wanna go further/fry a CPU that i'm borrowing) and it didn't get me a higher OC... but i think that 4.8 off of a 640 is plenty already :woot:

and temps never exceeded 41ºC in AI booster

[Sneaky]

someone on another forum asked for the same OC with my 2gb kit of RAM, so i'll share it with you guys: here's the CPUz dump for my set of OCZ 2x1gb DDR2 (OC'd a bit higher on the FSB than the mushy @ 1.55v :slapass: )

edit: even with my room at 19ºF, i never got any higher than i did before, so i think i've topped this out on water cooling... but god damn is it an amazing CPU

[afireinside]

So have you run ANY benchmarks?

grats ! nice 640 :slobber:
P4 rox @ 3dmark03 :toast:

NICE! can you beat my 03 score with a64? we have the same gfx card ;P

very nce indeed, as stated above Im amd all the way but its always nice to see ubber clocks on aging hardware, without sick cooling, water cooling @ this speed is ownage.

[Flib]

Water owns :clap:

ouaou man!!!this is a killing machine!!!A friends 640 goes with stock cooling 4.4ghz

stable?
have any links or results? :D

my 640's stock is 1.3875V, and it does 4ghz/w 1.4V what stepping is the 640 you're using?

[s7e9h3n]

Man, I wish I understood Intel language :p: If only my FX57 could do 4Ghz @ 1.4V LOL......

[LenniZ]

I can..P4 H2O X850XT PE '03 (http://service.futuremark.com/compare?2k3=4122266)

Very nice score! but what CPU speed?
CPU Intel Pentium 4 2537 MHz
Looks quite buggy :stick:

What is your 05 score?

[[cTx]Philosophy]

yah i know right my X2 doin 4ghz with 1.4 would ownageilationessnessadocious to the extrememodiliciousness

oh and I forgot to add radnessness

[Sneaky]

my 640's stock is 1.3875V, and it does 4ghz/w 1.4V what stepping is the 640 you're using?

IIRC its a SL7Z8 China

[PkG.1337]

640 rlly oc alot better then 540

[speed bump]

^^^ yep Intel finally got it right with the 6x0 series although I wouldn't say the DO 5x0 series are any slouch consider my 550 does 4ghz on 1.425v and stock cooling.

Cant wait to see what Cedar Mill does though.

[shark2]

Very nice score :eek:

it's like my 650, perhaps also little better :woot:

- Summer, July...approximately 27° Tamb:
4600Mhz dissy boxed
4758Mhz air with zalman
4939Mhz Tec cooling (TEC 226W - 13,5V - Twater 32° - Temp at system off max -11° - Vcore 1.7V real under load - Temp during system on under 1M Pi 18/22° very hot :p: )

all stable only for 1M PI.... I must still have the screen from some part :woot:


however, nice cpu sneaky...compliments :banana:



P.S. - sorry for bad English :slapass: :p:

[FUGGER]

That memory should to tight timing at that speed.

Kick the memory votlage to 2.2v and drop the timing to 3-2-2-4 4 recover and see if it boots.

"supposedly", CM does 4.3-4.4ghz on it's stock Intel heatsink

IIRC its a SL7Z8 China

nice,same stepping as mine, but you should try shutting down some background programs and such, @ 4.32ghz I can beat your score /w super pi 1.3 (27s ,havent gotten arround to get 1.4) :stick:

should i do this with my mushkin 6400 or my ocz 5400 plat?

[OverVoltage]

I got a 640 cpu and the most I can get out of it to boot is 265 FSB, CPU: 1.5v CHP: 1.8v higher volts don't help. It will POST up to 4.8Ghz 300FSB but locks up or reboots with a black screen, HDD light is always solid on attempted bootup. I am using a PCI card and an IDE drive. I seen on the 915 roundup on anandtech they got my board to 300FSB. Any advice how to get my CPU to boot at higher FSB?

[Sneaky]

i booted into windows @ 280 FSB and then used AIBooster on the asus board to get it to where i got a verified screenie of it


with your DFI board and the 915 chipset, you'll be hard pushed to OC any further with that - 915 chipset has no AGP/PCI lock, so i'm surprised that its over 250 FSB and still stable from what i've seen before


otherwise, try and find a clockgen for your board or some in-windows OCing gizmo

[OverVoltage]

BIOS have vastly improved with this board to help with ocing. I am not using any PCI-E card currently, got a voodoo 3 2000 PCI in there now while I wait for my GT to arrive, even before with my PCI-E BFG GT I got it to the exact speeds stable. I looked all over for a Windows clockgen and all I could find is one for the 925XE-T2V.
