Overclocking the 2500K - This is too easy

Ok so after running an overclocked Q6600 for 4 yrs it was time to upgrade... this new fangled hardware is just something else!

Disabled nearly everything, set multiplier to 45, vcore left on auto & was prime stable at 4.5Ghz, 31c idle & 62c under load. Easy as that!

Auto Vcore was running at 1.360v under load so went to manual at 1.300v, was prepared for some instability but it's rock solid in Prime, voltages being displayed in Cpuz are 1.304v idling dropping to 1.296v at full load & now maxing out at 60c.

Still finding my way around the BIOS & working out what all these new values mean, I figure so long as I keep the vcore below 1.35v & max temps under 70c I'll be OK.

Unsure how to determine whether I have a "good" chip or not, the VID gives different readings (unlike my old Q6600) & also not really sure how to squeeze the most out of this sytem, however 4.5Ghz is a good start IMO :)
 
Yep, they all pretty much get to that speed so easily which is why there is a 5GHz+ thread which is a little harder to get into ;)

No one...complain, all hardware should be this good ;)
 
I knew it was too easy! Was running on the integrated graphics just to get up & running, I figured once the GPU was installed I'd get better temps if anything as the CPU would be doing less work, however the opposite seems to be the case.

Once the card was installed the overclock failed, I nudged the Vcore up to 1.310v & am back up & running @ 4.5Ghz but things are getting a bit toasty, cores averaged at 64.5c after 40 mins on prime, highest temp on a single core touched 68c.

Looks like my cheap plastic case may have finally had it's day :( Removing the 2 floppy drive front panels & bodging an 80mm on to blast straight at the CPU cooler intake should bring things down a fair bit, that graphics card had divided the inside of the case into 2, the lower half getting all the fresh air.
 
even though that is a bit toasty, Intel chips are usually rated to take direct nuclear explosions! mate of mine once had a Cedar Mill (Pentium IV dual-core) that would frequently hit 91*C under load and it still works today! :D
 
68 is fine, worry not; remember Intel's CPU throttling doesn't kick in until about 90.

Plenty of people running i7s up in the 70s and not being worried by it :)
 
Upped the multi to 46 & left v-core at 1.310.. now cruising at 4.6Ghz with no probs, ran prime for an hour & temps averaging at 64.5c across the 4 cores.

I noticed a gradual rise in watts on coretemp, idling at 35w, going up into the low 90s for the first half our of prime but then as time went by the wattage exceeded the 95w I thought was the maximum wattage for this chip. After an hour it was up to 97.2watts so I stopped the test.

Bit hesitant about running prime overnight, I'm not worried about temps its this rising wattage that concerns me.

Any input anyone?

I've had mine over 128w when running LinX @ 5GHz :D

Increased power usage won't harm the chip, and is normal for overclocked chips. Caused a bit by increased clock speed but mostly by increased voltage.
 
ppl worry too much about temps. my laptop c2d hits 100c on a regular basis. its fine. id worry more about putting too much voltage thru it. if its stable, its stable, no matter what temp.
 
Laptop chips are, I think, made with a higher heat tolerance... And Core2Duos were 65nm, hence tolerant of higher temperatures.

2500K's throttle about 90 degrees, IIRC, so I think I'll trust Intel on that :P
