Q6600 Temps(not overclocked yet)

big.rich1976 · 23 Mar 2010 at 08:17

Hey guys,

Hoping someone can help, im getting conflicting CPU temps between coretemp which i run in windows and the hardware monitor in my P5KC motherboard in the BIOS.

My idle temps for my Q6600 seem to be about 44c to 47c in windows, However if i reboot and go into BIOS it shows the CPU as running at 23c. Which one is right. Im not getting any adverse symptoms but want to OC and need to find out which one is right

All the best
Rich

just to back up what i am saying, very frustrating.....

Stick with what CoreTemp is reporting. It is reading the actual core temperatures (Tjunction), whilst I suspect the other software is reading the Tcase temperature, hence the big difference.

CoreTemp or RealTemp are widely thought to be as accurate as anything around at the moment, short of having temp sensors installed within your CPU.

Although Tjunction is incorrect, it should be set at 90c to 95c rather than 100c for the Q6600. Which would knock the corresponding degrees off your temp reading.

Thats debatable. There are a lot of conlflicting views regarding this and no-one has ever 100% proved which (if any) of these are correct. I would leave it at 100c for a safety net.

Thanks for the info guys, so do these temps look high, under load at 3ghz per core it rises to about 55c

Diggsy · 23 Mar 2010 at 10:23

55c isn't high at load if thats the individual core temps, which, assuming thats your idle in the 2nd post (50c) then I have my doubts.

You're perfectly safe up to around 75c core temp on a Q6600.

big.rich1976 · 23 Mar 2010 at 10:33

Ah cool, thanks for the info.

No they dont look high. 51c is low temp for Prime95 load. Up the Vcore in bios to 1.5, clock to 3.6ghz then post more shots

Can safely go to 85c in coretemp, 90c is a bit too hot

big.rich1976 · 23 Mar 2010 at 10:56

I have actually changed the program i use recently to stress test the CPU recently, Have been using Prime95 but been using a different program called "intelburn" this appears to stress the CPU more then prime95.

Ok this is with the voltage upped to 1.5v, The ram is set to 2.10v in the bios. It is worth noting that the temps were jumping upto 73c but would drop back down to what is illustrated.

Diggsy · 23 Mar 2010 at 11:24

You shouldn't need the voltage anywhere near 1.5 for 3ghz!!!

I think Guest2 was telling you to try and clock to 3.6, at which point you will probably get away with 1.4, judging by the VID of your Q6600.

big.rich1976 · 23 Mar 2010 at 11:30

OK ill change the voltage, What should i be aiming for when running at 3ghz per core? I had it set to AUTO, Am i right in thinking the VID is what Intel guarentee my CPU runs at ?

Guest2 · 23 Mar 2010 at 11:30

Depending on his vdroop he may need 1.5. Mine is at 1.56 bios and gets 1.47 when loaded

A lower VID will mean a possible higher overclock, not a lower voltage (thats the way I see it anyway) May aswell 1.55v bios, 410 x 9 for 3.7ghz

big.rich1976 - Intelburntest on standard passes on my cpu, maximum lasts about 5 minutes before failing. Prime95 works for about an hour an half before failing on a core. Intelburntest standard is an easy test.

If you want proper stable, try maximum or leave price for 6 hours + Personally i'm never going to play a game for 4 hours that will max load all of my cpu cores

Diggsy · 23 Mar 2010 at 11:37

I would say with that VID you should be able to do 3ghz at or around 1.3v, maybe even a little bit less.

Just keep an eye on the other voltages too if left on auto, as some Asus boards are notorious for setting them very high.

Oh and Guest2 - lower VID does normally mean you can run the CPU at a lower voltage, but it doesn't always mean a higher overclock. Although most lower VIDs will, for obvious reasons clock higher.

The VID - the voltage that Intel certify the chip will need to run at on its default speed.

I think those temperatures are high, I had similar problems and I think you need to reseat the HS or get a better one.

Guest2 · 23 Mar 2010 at 11:41

Are right. My Q6600 that was 1.3500 vid was not stable at 3.3ghz. The one i have thats 1.3250 vid is stable (enough) at 3.6ghz

I suppose this isnt always the case but i would have thought that generally a chip would clock better thats 1.1vid over 1.3

It'll usually clock a little better, but the main advantage is almost always being able to do a particular clockspeed at a lower voltage - hence less heat.

Screw that, our house is cold and our electricity is included in the bill anyway!

big.rich1976 · 23 Mar 2010 at 11:51

The vdroop is a bit of a nightmare, I have set the BIOS to 1.3000v but cpu-z shows the voltage is actually at 1.160v and my VID is rated at 1.2625v so im below that at the moment. So which stress app do u think is the best? intelburn or prime 95, I have also used Orthos in the past.
