Got my Kentsfield QX6700 B3 ES! Time to Overclock!!

[managerman]

Hello...

I received a Kentsfield QX6700 B3 ES today and threw it in for a few quick tests...

I set the Vcore to 1.55v and ran four instances of Prime 95

I was able to boot into windows at 3.75Ghz but is was not stable enough to run any CPU intensive tests....

I ended up at 3.51 Ghz and it continues to run now...

Idle temps between 48-55C depending on core...100% load on all cores temps between 77-84C

I have attached a screen shot....I am going to try some more benches later tonight and tomorrow...

UPDATE: Quad Prime still going after 2 hours!

nice, lets see how far it can go

where did you buy the chip though?i thought it was suppose to be out next month

[markopoleo]

That seems crazy hot to me 70c under load? Thats like worst then old P4s did.

Nice!

I did not buy it....

The vcore being set to a 1.55 voltage would probably explain the temperature under load.

Remember, there are FOUR heat sources under that IHS. Each of them producing about 65 watts of heat. Thats esencially the same amount of heat that FOUR stock e6600's produce. Thats alot of heat. They're going to be hot.

Remeber, there are FOUR heat sources under that IHS. Each of them producing about 65 watts of heat. Thats esencially the same amount of heat that FOUR stock e6600's produce. Thats alot of heat. They're going to be hot.

It's actually 130 watts not 260. It's two conroe's glued together so it's 65*2 = 130 watt. And your temps are high!

[managerman]

I agree temps are high...going to try to back down the voltage and see if I can mainatin the current overclock stability...

I wanna see some 1M Pi action.

[Hassan]

heat is not too far out of line... I pull ~66-70 with each of my cores under 4 x sp2004 with water... if they are stable then let them fly

[Supertim0r]

1.35-1.4v should be enough for 3.5ghz

nice chip

Bring that rig over to XS WCG and put it in 100% use and then you will know if it is stable. Pi$$ on prime95 and all that other crap. Real world is what you will use every day and WCG will push it to the max.

[managerman]

I wanna see some 1M Pi action.

Update: I stopped the prime 95 after 8 hours.....and ran a 1M Super Pi......and it would not run it....made it about half way through then gave me an error..Ran multiple instances of 3dmark05 and 06 with no problem...hmmm....will play with it some more after work..

yep all the B3 are great overclockers, i try with my b3 and 3.6g is possible with a "normal" vcore.
its can run 1 super pi at almost 3.8gb on air, the B3 are amazing.

[XS Janus]

Crazy temps!!

Cupra....

Quick question?? Does your B3 have a large span in temperatures between cores 1 and 2 and 3 and 4??? For example...My cores 1 and 2 are about 6-7C higher in temps than cores 3 and 4..

yep i think that is ok.

core 1 - 78
core 2 - 77
core 3 - 75
core 4 - 73

[Richard Dower]

I'd have to have each core at 64C and no higher to feel safe.

with a quad cores at full load and air cooling - its not be easy thing

[markopoleo]

Now that i think about it, guess thats not "to bad" considering its 4 cores next to each other and the size they are. I wonder what happens if one core fails do the rest fail?

[managerman]

yep i think that is ok.

core 1 - 78
core 2 - 77
core 3 - 75
core 4 - 73

Thanks for the confirmation......More testing will take place tonight!!

just out of curiosity the cores have the metal above them (forgot the exact word) if u take it out u reveal the cores themselves for extreme ocing it should be better with straight cooling over the cores.

no metal cover. or that CPU companies should start developing better solutions like single metal cover per core ?

the one metal cover over a lot of cores ain't exactly optimal.
