just need to get my temps abit lower some how, i've seen 5ghz overclocks on the 2600k at around 70c, in hotter places than me aswell!

new fans should be here tomorrow, will get them fitted tuesday if I have time, should lower them abit more, will reapply the TIM aswell, hopefuly even out the core temps (2 cores run hotter than the other 2) not by much but hopefuly I'll be able to even them out some more, also ordering a new camera next thursday (hopefuly anyway) so will get some pics up!

fans should arrive tomorrow (hopefuly early enough that I can get them fitted and have a play about with things)

depending how much they lower my temps by I may try for 5ghz, not as a daily overclock though, still using 4.8ghz but I think I'll knock it down to 4.5ghz, depending on my temps smile.gif

after playing with a 2500k for over two months, I began to see degradation. mostly on the memory controllers I think, because It refused to run 2133MHz mem anymore. even at stock speed. I'd been toying with voltages around the 1.44-1.48v range with 1.14vtt. so now that I got a new 2500K I think I'll be trying to stay below 1.4v this time.

I'll be keeping the voltages as low as possible (obviously) idealy I don't want to go over 1.45v, but we'll see, also I see you have the B3 board smile.gif I've still got to send mine back but I really don't want to be without a system frown.gif hopefuly the RMA process wont take too long

also I have noticed i5 2500k's and i7 2600k's overclock to the same, with the same voltage (give or take a little) makes me wonder, was the 2600k really worth the extra? obviously yes for the e-peen but other than that? lol

Cheers!!

I just got mine up there too, was easy as cake once I put it on water. I haven't even increased any voltages over the stock 1.30 with vdroop set on high. It idles at 1.296V and loads at 1.344V...no errors yet, I guess I'll keep going. Just might hit 5 with this one...for once I think I got lucky..smile.gif

@Martinm210 nice chip you got there. mine needs 1.400V load for 4.8GHz. won't even run 4.7 @ 1.35 like you've got. shame, cause I got a good batch too or so I thought. my old sandy was even worse though. what's your batch #?

the extra cache is nice, and the sticker saying i7 of course is totally worth it biggrin.gif I would have gotten the i7 if I could fit it in my budget. that and I'd have gotten the Maximus IV just to match my red/black theme biggrin.gif but sadly money doesn't grow on trees. and if it did, there'd be very little trees here knowing my luck


Edit: also,I read somewhere that 2MB cache per core is where intel thinks is optimal. and I think 6MB is holding me back a bit. for example, while priming at low priority and gaming at the same time, I get random freezes for 5 seconds at a time... I thought it was just my old buggy gigabyte board but same thing with this Asus. so maybe there's some merit to it.

Yeah, I'm working on it, actually I did finally get a BSOD at the 1.344, so I bumped it .01 and it seems to be holding. I want this chip to last a while, so I'm looking to keep volts down below 1.4. I gave it about 10 minutes earlier, but I've heard the instabilities show up more in games than Prime, so I'll be putting in some quality gaming time too..smile.gif

It's a weird batch number, just bought it from egg last week. Batch# 3101A103

All the others are different. I'm happy so far, my Q6600 struggled at 3.6, so this is a nice upgrade 4.8 seems like a good daily OC so far. I'll push it up a bit further little by little and see what happens.smil3dbd4e4c2e742.gif

Looks like I'm definitely feeling resistance at 4.9, up to about 1.392V to hold. I'll play on this for a bit and maybe give it one last try for 5.0 later.

yeah I'm holding at 1.4. I don't want to push my luck. my last sandy I was never happy with and I kept stress testing new settings for weeks on end and eventually degraded it from all the priming at high voltage.

if you find something that works, I would stick with it. 4.9 is very good if you can do it at <=1.4 mine BSOD'd after awhile at 4.9 with 1.425v and that's the absolute limit I'm willing to give this. I'm still going crazy over that magic 5.0 number but I'm not gonna kill my chip this time trying to obtain it.

I had a Q6600 stuck at 3.6 too. darn thing fried 3 motherboards too before settling in on a gigabyte EP45 ultra durable. thats when I gained some major respect for the gigabyte brand. but they seem to have dropped the ball this time around. (I don't like Asus but they made a damn good P67 board)
