What does intel recomend being the hotest temperture that a B3 Q6600 can run and still be consider safe.with coreTemp what does Tjunction 100c mean.Does that mean each core can reach 100c and still be safe.

Don't go above 60.1 C or you will damage your CPU. Im sure they have a built in tolerance to that number... but I would not push it.

65 degree C is the max you should go for 24/7.

It will not damage your CPU.

Where did you get this number? It sounds official....I mean 60.1. But I've never heard that before. I was under the impression that as long as you're under 65C you will be fine.

60.1 is the max temp for the E6600. The quads can go a little higher.. ~65-67C.

G0 stepping quads can go up to ~86C for the Xeons. I think the regular Core 2 quads are ~71C or so.

It's on Intel's website somewhere.

Sweet, thanks for clearing that up.

wait, so what is it for G0? 71? (like for 24.7 overclock)
sorry OP

Here it is. It actually is 62.2 for the older quads which is a little lower than I thought:

http://www.heise.de/english/newsticker/news/89046/

According to Intel's Product Change Notification (PCN 107463-00, the combination of these two approaches allows processors to be cooled with less effort or with less noise. The current B-3 quad cores reach a TDP of 105 watts with a maximum temperature of 62.2 degrees Celsius. Intel says that a BIOS update is required before the new processors can be used on current socket 775 mainboards. (Craig Morris) / (jk/c't)

That same link states G0 is ~11C higher:

Intel has announced the release of a revised version of its client core processors Core 2 Quad G6600 and Xeon X3200/X3210 at the end of the summer for LGA775 mainboards. The new "stepping G-0" (instead of the current B-3) reduces power consumption by around 10 watts (Thermal Design Power/TDP) and increases the CPU's maximum temperature by around 11 degrees Celsius (TCase).

G0 Q6600=71c
G0 X32XX=86c

You can even operate your quad at 70 degree C as well, but are you willing to risk your CPU? it depends on you.

The only time you should hit 70+C is when stress testing your CPU with P95 or Orthos so as long as those are the only times that you hit those temps you have nothing to worry about as gaming or other programs will not get your temps anywhere near that high.

Are you positive about this? So no damage at all will be caused if running over 70C for a short time with a G0? If your right then I think I will go ahead and clock up to 3.4GHz (1.37v) if it's going to be alright hitting 71/72C for 8-10hrs of prime.

Im positive that one session of P95 at 10hrs with your temps at 71c will not do any damage to your CPU. When I stress test to find my maximum OC I always run right at the rated temps or just a little bit over and I have never had a single problem.

You have to remember that when you find your max stable OC and go back to doing normal things like gaming etc... your chip will likely never be pushed as hard as P95 or other stress testing programs are capable of pushing it so most likely it will never see 70c temps again. Most games and applications will only get your temps into the high 50's.


A lot of guys over at Xtremesystems.org are stressing the G0 Q6600's at 77C and are having no problems just for reference.

You just have to make darn sure that you are using the new Core Temp version 0.95.04 as this is the one that reads the G0's correctly.

Wow, 11C! That's quite something for a new stepping!


Yep, the G0 steppings are really nice. There is more to it than just a drop in the wattage rating on the new G0's. Supposedly the G0's have better silicon than the B3 steppings thus the higher temps, plus a long list of other issues were also fixed.

The 62.2 is based on a tcase reading. This is where the bios, and programs like speedfan derive their temps. If you go by DTS (Digital Thermal Sensor) readings, like core temp and everest do, you'll see totally different temps. tCase (bios) temps seem to always be about 15-20c lower than DTS temps, so 62.5 tcase/bios would probably be around 80c (DTS) if you looked at everest or coretemp.

DTS is more accurate since it is the actual measure of heat generated within the chip. tcase/bios seems to be more of a proximity heat measure.

Going by DTS, my cpu is good to 100c (throttle begins) and I've stressed it above 80c for hours when looking for my max OC. No issues.

So, just keep in mind when considering limits, what limit, tcase (bios) or tjunction (DTS), and what program you are using. If using bios or speedfan, uGuru, etc., then base your limits on tcase specification. If using coretemp or everest, base your limit on tjunction spec.

I meant B3 Q6600 not G0 Q6600.

Just run coretemp and see what your max tjunction is, but gabamanic is offering good advice regardless if it's B3 or G0, IF we are talking core temps and not bios temps. Remember, bios temp is at least 15c lower than core temp, so if you are hitting 70c bios temp, you are at least 85c core!

70c core temp is a good number. The brave can go beyond, and as was said, the things you do on a daily basis will not get anywhere near where 4 instances of P95 running small FFT's hit. This is why I base my own max oc on 80c.

I think he wants to see a modern cpu catch on fire. Not sure why though.

I bet he tortures small animals too. :headexplode:

So I guess I am safe ,I am running my B3 Q6600 at 3.5gigs at 1.425v and with coreTemp and running Prime 95 at the hardest settings, after a hour I am running at
Core#0 58c
Core#1 54c
Core#2 58c
Core#3 54c
