No reason he can't get 3.8ish stable as long as temps are good.

1.65 is not crazy volts for a 65nm chip.

3.8 is do able of course, my Q6600 did 3.83Ghz @ 1.58v.

But yes 1.65v is a bit too high, it won't last very long at those volts.


And no of course the vcore isnt the only thing you need to get it stable, but i GUARENTEE you wont get 4ghz on that q6600. If I put 1.65v through my Q6600 I could boot at 4.2ghz

ok let's put it this way. he allready did 4ghz stable but he didn't like his temps so he backed down to 3.6ghz

and i'm not saying it was with 1.65v he only tried that but couldn't get 3.8ghz stable with it.

there must be another thing that is not making this stable

So he got it 4ghz stable, backed down to 3.6 due to heat, tried to go back up to 3.8, and couldnt get it stable even though youve tried a bunch of things including 1.65v vcore?

Either he was lying and it wasnt actually running at 4ghz before, or its massively degraded, hence the lack of stability at higher speeds that were lower than what it used to run.

Running 4ghz stable on a Q6600 is pretty damn rare, and wouldve required a HEAP of vcore, so I bet it has just degraded a fair bit.

rly?

he is not lying i was there when he was done with prime. this isn't a vcore issue this is something else voltage on something other than vcore.

we couldn't get 3.8ghz working so we wen't straight to 4ghz and that worked but do to heat he backed down so we are trying to get it to 3.8ghz

he is running 3.6ghz @ 1.48v i think

I was being sarcastic. But seriously your not going to be able to cool 1.65-1.7v

EDIT: Just get a 45nm quad for pete's sake!

Its totally possible to get a q6600 to 4 ghz stable but it would likely only be possible with a low vid like 1.2 - 1.2250. Both my chips with vid 1.2125 and 1.2250 i had easily boot at 4.4ghz, the 1.2250 even booted at 4.5ghz. I had both semi stable at 4.0ghz with a 1.65vcore, no it not suicidal. The clocks were stable enough for general use and would only crash when priming more than an hour. For me they were stable enough. This was on a Gigabyte P45 Extreme. Sorry i cant help you OP because i cant remember the settings, but i did mess around with the GTL buffers and all that other crap, just wanted to point out MY chips did not die running 1.65vcore for a year and are still running strong.

Let me get this straight OP. You had a stable 4Ghz but you backed out because of heat right?
Now you are asking here how to get it to 4Ghz... Clearly if heat was the problem the way to get to 4Ghz is to get a better heatsink.

Post your settings so we can help instead of hearing people say what "can't" be done.

You just need good cooling. These current settings aren't 100% stable as it gave me some "you are not stable" message at the 5th run but I run this all day on this motherboard which is about as budget as you can get, 4 phase power and all...

I almost have no doubt I'd have this running 3.8GHZ with 1.55-1.6v if I had a motherboard that could do it.

To all you people who say you can't get a Q6600 over 3.6GHZ stable, I laugh at your face. I can get 3.65GHZ stable on a 4 phase...

Edit: Unfortunately since I have a motherboard that is as low grade as it is, I had to ghetto volt mod it so the idle voltage pushes nearly 1.7v just so when the load kicks in the vdroop only drops to 1.477 ish. Unsafe you say but It's about upgrade time anyways.

There is a difference between being stable and just ignoring the stress tests. If you get errors or crash out during a stress test, it's not stable. You might be able to use it solely because what you're doing isn't reaching the maximum capabilities but that doesn't make it a stable clock. You're just blindfolding yourself from the fact that you're most likely damaging your system from running an unstable clock.
