iv just overclocked my Q6600 to 3GHz and have been running prime95 for about 2 hours. the temps are 61, 61, 57, 57. thoes are all max temps from the last 2 hours. idle temps are 34, 36, 31, 31. do all thoes temps sound about right?
also it is now drawing 1.39V how much can it take before it dies? and would it be worth taking this off auto and setting it at 1.39V myself in BIOS?
cheers
That looks OK. If you take the voltage off auto, you could probably decrease the voltage a bit, meaning less heat. But you will have to test it is stable again
It will all depend on what voltage was required to achieve stock clocks (i.e. 2.4GHz) but definetly turn off auto voltage control it vastly over estimates the required voltage.
Personally I would check stock voltage then see how many steps you have between that and the current value, choose the point in the middle and check for stability. If it crashes then take the half way point between the new voltage and what auto suggested, test again if its good lower it to half way between the new stable and where it was unstable, lather, rinse, repeat.
So an example with numbers
Auto suggests 1.4v stock was 1.2v and in this assumption we have all the voltages in between.
So we have two known parameters a = last stable voltage and b = last unstable voltage we have unknnown parameters in the form of c = Difference between voltages and d = new voltage to try
We need to follow a simple optimisation process shown below,
1. a - b = c
2. (c/2) + b = d
3. Test for stability
4. If stable d = a, if unstable d = b
5. Return to step 1
So in our case starting values are a = 1.4v and b = 1.2v
1. 1.4 - 1.2 = 0.2
2. (0.2/2) + 1.2 = 1.3
3. Stability Test = Unstable
4. Unstable b = d
1. 1.4 - 1.3 = 0.1
2. (0.1/2) + 1.3 = 1.35
3. Stability Test = Stable
4. Stable a = d
1. 1.35 - 1.3 = 0.05
2. (0.05/2) + 1.3 = 1.325
3. Stability Test = Stable
4. Stable a = d
and so on until you find the lowest stable voltage.
You could also try running IntelBurnTest as it is able to stress your whole PC in a matter of minutes and if it passes then it is equivalent to a very long run of prime/orthos (something like 20+ hours).
But beware if you do try it because it will seriously stress your hardware - your temperatures can be up to 20 degrees more than prime!
When I read this before trying the program I thought it wouldnt apply to me due to a big case and plenty of cooling but no I was wrong. This program took my CPU temperatures to within 5 degrees of the throttling threshold when the CPU begins to slow itself down because of the extreme heat. This was 20 degrees higher than my load CPU temps under prime.
My fully stable OC which ran for 10 hours under orthos with no problems failed the test within approximately 10 minutes with a peak CPU temperature of 79C!
No idea what the program does but Ive never seen anything like it. Apparently its what Intel use to test their CPU's.
LOL
Just ran the Intel Burn Test and it did raise my temps more than Orthos.
Idle Temp: 30°C
Orthos Load: 44°C
Intel Burn Test: 52°C
Not quite the 20°C people talk of but still respectable, oh and in case anybody is wondering yes my overclock came back stableSee my CPU-Z Validator Box/Link thingy below for specs click for a better view!
Use http://processorfinder.intel.com/ to find your max VCore. For a Q6600 1.5v is the max.
what cooler are you using?
ok thanks, ill try intelburn test later and also have a go at setting te voltage myself.
the cooler is a scythe ninja rev plus B
