My 2500K temps + AI Suite issue

post #1 of 12
Thread Starter 
I'm a long time overclocker, more of a lurker in the forums but I've been overclocking my rigs for the last 6 or 7 years...

I went and picked up a 2500k and an ASUS P8P67 PRO last weekend to replace my e8400/evga 750i ftw. I'm a bit concerned about my new temperatures.

When I let ASUS's motherboard / AI Suite "auto" overclock, they both set me to about 4.32GHz(103bclk x 42 multi) in Turbo Mode with a 1.195vCore. This is a great overclock for me considering I'm going from an e8400 @ 3.6ghz. Games run amazing, my 2 overclocked GTX 465's have now become my bottleneck (weee!)...

But of course I'm here at overclock.net because I like to push things to the limit, not just sit at the first setting I get. I've been messing around off and on all week trying to get a more stable overclock around 4.5, and I'm having some issues.

At the "default" overclock of 4.32GHz I'm getting idle temps around 35C and load temps around 65C and up to 70C. When I'm running Prime @ Small FFT's both CPU-Z and AI Suite II show my vCore pulling 1.265v.

I've got a Hyper 212 Plus cooler along with an Antec 900 case...so plenty of fans going (granted they are all on low settings).

I tried manually overclocking to 100BCLK x 45 multi and got into Windows just fine @ 4.5GHz with 1.3vCore and started running Prime95 and my temps shot through the roof up to 80C so I quickly shut down and undid my overclock back down to the original.

Are these temps accurate? It seems awfully high considering I'm running a pretty decent air cooling setup, with decent ventilation...I'm in New England so my ambient room temperature is around 70F...My e8400 ran just fine in the exact same case with all the same peripherals. I just don't want to ruin this new chip because honestly its amazing at even 4.3GHz but I'd love to get up to 4.5 or 4.8 and stay under 70C...am I doing something wrong?

Also, a bit more of an annoyance, but a question for anyone using AI Suite II.
My "BCLK Frequency" shows up in AI Suite stuck at 4.2MHz (the minimum BCLK Frequency setting in the slider bar) so when I let it "auto tune" it never actually reports the correct 'final' overclock because it just multiplies the multiplier by 4.2MHz.

they seem higher then other people are getting.

Are you sure your cooler is seated properly, making good contact with the CPU?

I am having the same problem but with Noctua NH-U12P SE2. The temperatures are 56C at full load on i5-2500k default clock. When I tried to overclock to 4.5Ghz, the temps went up to 69-71C at load. I checked the cooler and everything seems to be installed ok, thermal paste ok, fan working...

I'd like to think I mounted it correctly, especially since I went from the beast that is Tuniq Tower...but you're right it wouldn't hurt to double check, gonna shut down and check it out. I'm gonna throw all my case fan's on high just to see if I can get the case temperature a bit lower...thanks for the idea.

your chip may just run a tad bit hotter than most. even still thats a damn nice overclock, and its still running cooler than most 45nm cpu's would at that same overclock. i wouldnt let it get much higher than 80 c tho.

also the 212+ is one of the harder coolers to mount because of the retarded direct heatpipe touch. try putting thermal compound in the gaps and smooth it out with a old credit card(like brick work almost) then put two small vertical lines on the two inner pipes. this is how i mounted mine with great results on my moms i3 rig.

that actually is decent. 71c for a 4.5ghz oc is not bad at all.

I think I may have spread too much compound on now that I've read a little bit into mounting the 212+. I'm going to pop out my cpu and remount later on today...really appreciate the input. I'll give the results after I've done that.

Yeah it took 2 reseats of my 212+ to finally get the right temps. Originally when I mounted I had 72-77C, but redoing the thermal paste led to 10-12C drop in temps and now I'm at 60-62C.

With a Tuniq 120 Extreme in an Antec 900 case, my temps at full load at 4.5Ghz range from 61 to 71 (I have a spread of almost 10 degrees C between one of my cores and the other three cores at full load). I took my time when mounting the cooler on the CPU, particularly with the application of the thermal paste, so that I could avoid having to reseat the cooler.

dont have u to put more TIM on hyper 212 because of direct heat pipe thingie?
other than that get more case fans xDDDDD

Hey guys, sorry for the delay, ended up going out for a bit but I did get a chance to reseat my CPU/heatsink.

I reversed a case fan that I had as exhaust to intake, now going with the airflow of the Hyper 212+.

I definitely think I had too much thermal compound when I first mounted, now I've got a stable 100x45=4.5GHz overclock @ 1.3vCore (I haven't even tried going down with my vCore yet, I probably could...) my temps under full load (small FFT's) never hits 70c, barely made it up to 67/68c.

When I have free time I might try seeing how low of a vCore I can stay at 4.5 stable, and I might see if I can get to 5GHz while under 1.35v...

Thanks for all the tips, and take this as a reminder that with thermal compound, less is more!
