Are these idle temps ok?

My i5 2500k idles at ~31 degrees (there's actually a 4% load lol i guess thats idle enough though)

It is overclocked to 4.8 GHz however speedstep is enabled, so it is underclocked to 1.6 when im not running anything.

More about : idle temps

ok. ill do that now, also ill add that i played bf3 for like an hour, and the max temp was 69, this with 4.8 ghz the whole time.

ok im quite confused as i got a BSOD while playing skyrim, do not know the cause. I am going to run prime now. what options do i choose when i run it? please help?

Small for cpu stress, large for max temps, blend for mix.

Run Blend for a couple of hours and see what happens.

I usually try to run prime for 10 hours+ before I call my OC 'stable'. 24 hours is even better.

And watch your temps at 100% load.

ok so hang on
A)what exactly do i choose to make sure the oc is stable?
B)how long does it run for?
C) do i monitor the entire test?
D) What do i watch for?

Well...

Ideally you run each one for 10 hours+.

But, you can start with blend or small fft. Just start running it until you get an error in one of the workers or you get a BSOD. If you pass 6 hours, you are good; 10 hours you are great; 24 hours and you are golden.

Mainly watch temps for the first 20-30 min of the test to see where they stabilize at.

is it not smart to leave it running overnight? if i do, which option do i choose in the program? also could my initial bsod during skyrim have had something to do with the vcore?

Its not a problem to leave it running over night. If your OC isn't stable, one of two things usually happens:

1) a worker stops and the computer otherwise keeps running
2) you get a BSOD and your computer either shuts down, or restarts.

Beside the extra electricity usage, its not a problem.

ok last questions before i do it.

1) Which choice do i make in prime95?
2) How do i know if one of the workers stops, like what does it say?
3) What could the possible cause of my intitial BSOD be?
4) What temperatures are too high?
5) If i find that it failed, and report back here, can you help me out with what i would have to do next?

Thanks so much for the help so far by the way

1) just choose the default; it should be a Blend Test.
2) If a worker stops, you will see a msg in the worker window and also a msg in the main window at the top.
3) 90%+ a BSOD means that you don't have enough core voltage
4) for an i5 2500k I would personally try to stay below 70'C on your hottest core
5) Yes I or someone else can help you np. If you need to, you can PM me or just open another thread :) 

yw and have fun with it :D

If you want faster results you can run the Intel Burnin test. Takes less time but will stress your CPU way more than Prime95 will. Your CPU will also hit higher temps. My QX6850 hit 80c when on a Zalman 9700 in Intels Burnin test only 65 with Prime95, but only 65c when on a 9900Max and 50-55ish in prime95.

I try to run it with maximum memory but Standard for 10 passes is good too.

Do you use OCCT or just the Intel Burn In Test?

its been running for ~20 min now and I've seen it get up to 80. so i guess that i should abort?

OCCT is based on Linpack, the same thing that IBT is based on. In fact Linpack is from Intel.

I used IBT though. I have read people saying IBT doesn't stress as well as Prime95, but my CPU temps at home (on my Q6600, QX6850) and the ones at work tell a very different story as they always run hotter than what Prime 95 can do. And its normally instantly hitting those temps.

I ran Prime95 on my QX6850 when I was overclocking it and it was fine for 4 hours. Got my machine home and ran the IBT and it BSoD after about 5 minutes. Had to move to the 9900Max for better cooling and change the voltages and FSB/multi. Got 3.5GHz stable with less than stock VID (VID 1.325v, running 1.28v) and even pushed it 20 passes which was about 25-30 minutes in IBT, which as I said before was 5 minutes and BSoD.

What cooler are you using?

And remember these temps are not what will hit when gaming but still you normally want to stick around 60-70c on those CPUs.

1.4v looks to be normal from other for 4.8GHz. But I think you need a better cooler like the H100.

an extra fan will give you like 3-5'C cooler temps usually.

When you get another fan, try to get the same make/model of the existing fan, or buy two new ones, so that air is flowing smoothly between them.

if they have the same cfm I would put the one with higher rpm as the push fan.

so i have been running prime 95 for ~2 hours now and the max temp so far has been 77 this is with 1.41-1.42v
how is that?

it was not stable (couldnt boot) at anything below 1.4

Too high for me personally. I try to stay below 70'C and below 1.4v.

For example, my main system is 4.5Ghz @ 1.36v and 100% load temps are ~60'C.

its leveled off with the first core at around 65ish the 2nd and third at around 68 to 75 and the last one not hitting 70.

are these temps acceptable? is there anything i should change?

Those temps are in the 'safe' range. But watch out for ambient temp changes. When the seasons change and it gets hotter outside, your cpu temps will most likely increase as well. Don't go above 80'C on your hottest core for any long periods of time.

0124 means you need more voltage to stabilize.

Or, you need to back down the multiplier.

Edit:

4 hours is pretty good though :)
