ATM there are no suppliers of Phase change coolers. If you want one you have to go to the US and it works out about £600 its the carrage that kills it.

If you are interested send me a PVT msg. If you cant do it on this site iam on OCC.
 
Pretty sure Gray Mole stopped making them a couple years back as he emigrated to another country. Go over to the BenchtecUK forums there's a few guys on there that still build units as far as I'm aware.

There are in fact quite a few builders in the UK. The problem is though, that none of them build units for retail sale. The builders that are active, only build for themselves and peeps that they know, the same goes for repairs.

It was Johann that emigrated, to south Africa i think. Grey Mole stopped building because of health problems, his hands as far as i recall.
 
Not played around with the 19 multi, guess the extra memory bandwidth at the same clockspeed as using 21 could be useful in some situations.

If the extra bandwidth is there when why are people not using the 19x?

I have it prime stable now and am just finishing a Blend run.

A lot of peeps want to be able to run at 4.2ghz+
Using the 19 multi, they would need to be running BCLK at or over 221.
There are still a large amount of mobo's that will not cold boot at anything over 215 BCLK, let alone 221 BCLK. This would be the major reason for not running with a 19 multi.

Thanks for clearing that up.

4ghz 24/7 prime stable is fine for my needs.

In fact getting this D0 4ghz prime stable has been quite tricky in all honesty,

Easy to boot and run super PI etc... but prime stability was something else at below 1.285v
 
I've got my 920 D0 running at 19x211, 4ghz with 1.29 vCore Prime95 stable, but for 19x200 it only need 1.25 vCore. Is it normal to need such a large jump to get stable at 4ghz? And is it really worth it? Which bring me on to...

Am I correct in saying that under 1.3v is really quite safe and not really going to burn out my CPU by any noticable amount?

I have also left everything in the BIOS at Auto apart from the vCore, is it ok to keep it like this? Hopefully is not going to automatically put some value up higher than it needs to be and risk burning something else out faster than it really should? Mobo is Asus P6T SE.
 
Who is prime stable at below or at 1.285v?

And I mean an 8 hour run....


Looking through this thread again there seems to be a lack of 8 hr run primes.

I'm going to have to be old school easy again and insist on proving the 4ghz 8 hr prime run.

This 920 D0 has been a bitch to get prime at these volts.

EDIT just looked:

Some people are claiming 1hr prime suitability at low volts.

Na,

Not having it

Post 8 hr prime shots for your 4ghz goodness please.

end of cheers

I used to consider 8 hours quite stable until one day I left it priming while at work, i came home to one of the cores having an error at 7 hours and 55 minutes. :(
 
Whole world and his dog got i7 920 now. I've got i7 860 and will be oveclocking v. soon and good guides I should follow? Thanks
