Default Re: Q6600 now at 3.6GHZ and stable!

I will do

All components differ, but my motherboard is an extreme overclocker. Its had a lot of reports of it being able to support a very high overclock indeed.
It doesn't support dual GPU's though at full 16x speed, so running in Crossfire is a no no.

I'm not going to push mine past 3.6GHZ though. I've definietly finished.
I'm just going to try and keep forcing the voltage down, until the computer doesn't do stress testing/or doesn't boot up anymore, so I know the minimum CPU core to set.

I have the memory running at 900mhz from 800mhz at a 1:1:1 ratio, and don't know how much performance I'd achieve making it run at 1:1:20, and 1:1:50, if any.

Just got a blue screen, after quite a while in Everest.

I've set timings of the RAM back, and set the speed to 400mhz at 9x multiplier, to gain the same speed, and left the voltage at what I got it down to:
1.4675V

I'll see if it bluescreens again after a while. If it does, I know to increase the voltage.

That is very cool kage. How many case fans do you have in the machine and all?

Second was to overclock it to 3.2, again, very easy (I didn't even have to up the voltages).

Well today, I played around again, and I successfully have the Quad running at :

3.6GHZ!!!
Well done mate, that's a very respectable oc on air.

kage your zalman is set on low?
crank up the speed you could probably get 4ghz if you pushed it hard enough

Haha, thanks

I'm happy with 3.6 I know, if I push it anymore, the PWM temperature at least will reach scorching point.

With the overclock I have with the fan speed almost at low, the highest a core gets is around 66 degrees C when really pushed.

The Zalman is too loud for my tastes on full for normal useage too.

It was running Everest then though for 1 and a half hours, and was still running, so it must have been the RAM at 900mhz that stopped it before.
I still had the voltage at 2.0 for that though, so maybe upping to 2.1 will fix that.

As for fans, well, theres 2 front 120mm fans, the CPU coolers fan, a back 120mm fan, a top 200mm fan, the GPU's fan, and the PSU's fan.

All in all, 7

Well glad to see you have sufficient cooling! That is very neato. You should do an overnight burn in and see how it works

I might do actually

Is anything under 70 degrees C fine? Like if all cores did get to 67 degrees C for example in a worst case scenario?

Or is anything above 60 really lowering my CPU's on time?

i would say do not go any higher than you have. You are probably lowering the life of the processor running it at above 60C under loads. Not a lot I wouldn't think, but still some. Besides, you simply don't want to be running hot anyways.

You're right on the edge of the thermal specification at 70C (Q6600 G0 at Intel) so keeping it as low as possible will prolong the processors lifespan.

I think it's a toss up of that extra 0.4GHz or even 0.6GHz v the heat, is it worth it?

Personally I think 3.2GHz or even 3.0GHz is perfectly fine for every day use (I'm at 3.0GHz) and I'd only run at 3.6GHz 24/7 if the temps were reasonable. I'd crank it up to 3.6GHz on air for benchies though and 24/7 during winter maybe, wouldn't need a room heater then.

Did you do a 3DMark06 run with that 3.6 and a gpu oc?
