Q6600

I'm running a Q6600 B3 with a thermalright ultra 120 w/ scythe s-flex fan. I have been running this computer at 3.0ghz @1.3125. (VID is 1.3). I decided to try to push it a little further now since the value has gone down.

I'm running 3.2ghz @1.4125. Temps under prime95 using coretemp are 64 on two cores and 54 on the other two.

Is this temperature safe? How high of a vcore is safe?

Edit: Anyone want to show your settings if using a gigabyte p35 board?


Thanks.

well they say your not suppose to go over 1.5 vcore to be safe. 64C load temps are not bad. what program are u using to monitor your temps?

I have an E5200 in my G'byte P35 board.

The text editor apparently does not handle spaces and tabs well. :(

I might try lapping the 120 and maybe the processor. I still have sand paper from lapping a 212+.

Going for 3.4-3.6, I have the vcore set in the bios @ 1.45.

In cpu-z during Prime95 the vcore only says 1.312. Is it just me or is that a huge vdrop? Btw temps at 67,67,57,57.

I suppose your 10C difference in temperature is ok...but it probably means your thermal paste isn't covering all your cores equally. It's up to you if it matters to you. I usually only see a 2-3C difference in cores.

as you can see in jsc's bios he has load line calibration enabled which would help with the drop in voltage.

I'm thinking its been so long since I applied the AS5 some of it might have dried up.

I have the Q6600 also, not OC and paired with a XIGMATEK HDT-S1283. When I had my old case I had the fan on the heatsink blowing out the back with a 80mm rear fan. In my new case I have a top opening so I switched the orientation of the hsf so the heatsink's fan blows from the bottom and the 200mm fan is pulling from the top. I found this even out the temperatures in the 4 cores, now I only see about a 1-2 C difference whereas before I was seeing about up to 10 C (temps while idle). I'm thinking with my older case the heat was building up near the top so those two cores were a wee bit warmer then the lower two?

EJ, I have the heatsink oriented vertically in my Antec 900 cases. My reasoning was, "Warm air wants to rise. Why fight physics." :) 

On that board, I tried with and without load line calibration. I got better results with. YMMV.
