Overclocking a Q6600 G0 (Temps)

per intel spec 71C or less for that stepping.

did you use artic silver? how much voltage is going to your cpu? your load temps seem a tad high for only 2.7ghz. I hit around 68C on hours of full load at 3.42ghz.

ummm... is the c1 function disabled? if i remember right, that will keep your cpu from clocking the multi down.
 
temps still seem a little high even with C1E disabled, I would re-seat the HSF.
 
Those temps are not good. Is this the stock heatsink? On my Q6600 @ 3.6 with a Thermalright Ultra eXtreme 120 my load temps never go much beyond 60.
 
The 71C Intel spec is a case temperature recommendation which is aimed at system designers. This spec is obtained by cutting a groove into the top of your IHS and installing a thermal couple in the geometric center. Not many users are actually doing that.

Intel recommends keeping the Tcase temp at a maximum of 71C. They recommend this because they know that will reduce the chance of any thermal throttling. That doesn't happen until the core temperature reaches 93C or a couple of degrees away from TjMax.

Here's a screen shot showing the first evidence of thermal throttling. Core0 has just started throttling while the other 3 cores are still OK and running at full speed.

It's still running Prime95 small FFTs and is perfectly stable. If you intend to overclock your Quad beyond 2700 MHz then you'll need to keep the temps down but with a mild overclock you have plenty of headroom so don't worry about temps. These processors do a great job of looking after themselves.

The most important thing is stability. If you are stable then you really don't have to worry too much about core temperatures.

Edit: I had to turn my CPU fan off while running Prime small FFTs to get those kind of temps. Even after 10 minutes, the temps didn't go any higher. It throttled core0 and core1 which kept the temps from getting too crazy. Core2 and core3 never reached the throttling point.

If you think I'm insane then check out what one user sent me.

He was trying to find out where the thermal shut down point is. We sort of agreed that it is not until a core temperature of 125C which is what Intel rates the mobile processors at. They don't seem to list that spec for the desktop chips. No worries.
 
regardless of what definition you use for tcase, the majority of oc'ers on the [H] will tell you to keep your cpu at 70c or less under full load if you'd like to keep it around for awhile.
 
ya i have a scythe ninja on my Q6600 and highest i seen was 59c.

it is passively cooled, if you call it that. has 120 and 200 right next to it exhausting air so it gets good air flow so i wouldn't really call it passive, but still no fan strapped to the heatink and i see better temps in core temp.

also if you are going to reset the heatsink do a quick razor blade test for flatness. see if CPU or heatsink is not flat.

also i think you can back down the core voltage. i got to 3gz with no voltage increase and only took a little more to hit the max of this cpu of 3.2. not a great overclock by any means i think you should be able to more speed with less core voltage.
 
hi there, this may help you......i overclocked my q6600 g0 stepping to 3.0 ghz and im using a thermaltake v1 HSF, heres a screenshot, mine was stable for 26hrs while running prime95 small ftt's torture test with round-off checking enabled, all 4 cores working at a 100%....
i hope it helps....let us know what happened with your results : )

I would say a lot of it depends on how you plan to use the CPU. Keep in mind that the different prime tests, despite all taking it to 100%, will result in widely varying temps. If you're like me and mainly play games with it, the temps it could theoretically generate under the hottest test may not be relevant to you.

I would actually say if you game, you need to run small fft. The test will get your temps really up there. Although gaming will not get your cpu this level of action (very generally speaking), it does help simulate temps that may occur due to a smokin hot gpu being in the rig.
