Another 2500k thread

Hi all,

got a 2500k overclocked to 4.2GHz (using gelid tranquillo rev.2), all works fine idle temps are low 40, while gaming for several hours (Skyrim) using the Intel gpu doesn't take the temps overs 55-57 but when I run prime95 it goes to 69-71 - should I be worried about that or is that still acceptable?

I've re-sited the cooler once already and tried my best to do it bit by bit also used arctic silver 5 but can be done again if its seems "not right" ?

What voltages are running through it at 4.2Ghz?

Temps look OK (idle temps are warm'ish but it's the load temps that matter.) - and will be relative to your voltages.

Your gaming temps are good, and the main/major stress that the CPU will be subjected to most of the time (at a guess), - prime 95 abuses the CPU far more and constantly which is why the temps are higher.

It won't make a massive difference but Arctic Silver 5 isn't fully cured until the system has been running for 200 hours including several hot/cold cycles.

Thanks for the answers and sorry for the late reply as couldn't respond over the weekend.

I have to confess that I've used the 'OC Genie II' for my overclock (never before had the hardware to try some real overclocking) and had a really strange situation on Friday when the PC just stopped responding and after a hard shutdown it started to power off 2-3 sec after power on. In the end switching of the OC Genie + CMOS clear + swapping the RAM over (which not sure how it helped as I'm running fine on both now) helped.

I've then had an another look at what the OC genie does and only then I've noticed that it set the ram voltage to 1.65 which seems a bit excessive - altough I'm no expert, turned the damn thing off anyway...

Going to try a proper overclock now, I know more-or-less what to do with the cpu voltage / multiplier and there are plenty of other threads on the 2500k but its the RAM which is puzzling me a little bit.

Its running on 1.5v 1333MHz on stock - my RAM so would like to get them to at least 1600MHz but should I even touch the voltage for that or what should I do to take it further (if advisable) ?

My mobo just in case.

Any input appreciated.
