Pentium D 631 Overclocking 5669 MHz

[TheGanG]

One of my buddy sent me recently a Pentium D 631 and i tried it's ocing capability and working on it next week too...
It works with low voltages and temps, nice chip. But i pushed voltages higher to get some 3DMarks test...

not a bad oc result, but I think current c2d can out-performs it at lower clockspeed:).

I think the fun of this is just pushing it to the max, rather than going for the best performance.

Yeah, right... Just for fun...

Is this with the DICE chilled water still?

It amazes me how far P4's can go with just a tiny increase in FSB speed.

P4 631 WR is 8 GHz!

Not dice chilled but i used iced water with TT BigWater 760i...

hehehe, i do agree on that. It's all about bragging rights.

Only 1.5v? Time to bump up the vCore...
Remember you have nothing to loose.

[TheGanG]

Higher voltages for higher MHz = higher temps...

Pi sucks... Unstable

[DMB2000uk]

Wow, that thing is getting toasty.

When does thermal throttling kick in on P4's? I always thought it was 80oC.

Dan

[TheGanG]

Works overheated as well (100+ celcius) but like a stupid, it takes twice as long to take a super pi...

[martini161]

yeah, its being throtled.
dan: the p4's is around 80c but pentium d's tend be very hot any way, so the t junction is higher, this is cause they did what intel is doing with the quads now

[DMB2000uk]

Contrary to what the title states, this is actually a P4, so yeah, it's throttle point is 'pretty low'.

Dan

[martini161]

well excuse me for not reading the OP

[vicaphit]

Too bad you can't keep a processor running like this for a long while with chilled water...

[TheGanG]

i have better ideas about termal thingummy ...

[martini161]

nice block! i asume the dice goes in that bowl thing ontop?
