New build 2500k

Burtoner · 22 Nov 2011 at 08:06

Just got new build Intel I5-2500k with 8gigs of ram and Asus P8Z68-V Motherboard.

I'm using stock cooler everything running at 29 degrees idle. Under load up to around 46..

I was wanting to overclock this chip but have no idea what settings to move..

I tried the own Asus software to overclock but it just restarts and never stays on...

As you're using the stock cooler i would only aim for ~4GHz.

Go into the BIOS disable Spread spectrum and Turbo Boost and input the memory settings manually (or use the XMP). Then make sure the memory is running sub 1.58V if your memory's spec is over this volatge.

Then up the multiplier to 40 and leave everything else on auto - save and exit.

Once in windows run Prime 95 or IBT and check temps with real temp...

I have the same, I'm currently running mine at 4.5ghz. I'm using Coolermaster Hyper 212 plus atm. I have tried the Noctua D14 which was only 2-5 deg celsius cooler (running at same overclock) than the hyper so I returned it. To me it wasn't worth 66squid.

I will get my settings an post here in a minute.

here goes:
RAM is a bit undervolted and overclocked a little

Burtoner · 22 Nov 2011 at 22:51

thanks will have a go to 4ghz, but am in process of looking at an aftermarket cooler, any recommendations of cooler?

How much do you want to spend?

Plec · 23 Nov 2011 at 09:35

A couple of examples:

Gelid Tranquillo - link - @ £26 is an excellent midrange cooler for the money. ANd if you want a healthy clock with out spending big bucks then this is worth considering (although you may need to sho around for stock).

The Silver Arrow - link - @ £55 is the best performing premium air cooler, when comparing price to perfromance ratio, and if you're after a high clock with silent running then this is a great buy (if it will fit your case and setup - i.e. it doesn't like high profile memory and you need a case that can accomodate its height).

Unfortunatley, you will need to google for suppliers with stock.

I'm using the Gelid Tranquillo, and currently run the overclock at 4.0ghz and my idle temp is at 47 degrees. Ambient temp in room at about 20 degrees. I thought that was quite high.

I have 1 rear exit fan, and 1 front intake fan on the case as well.

p.s. I have a different motherboard than you though, but same CPU.

That is quite high for idle temps - what are your load temps like?

Idle temps are usually not that important - as long as the load temps are within the expected range of the clock and cooler.

If your load temps are high for 4GHz (which is a minor clock) i would consider reseating the cooler - as it may not be making full contact with the CPU or you put too much or too little gunk on.

Additional: Is the clock a manual clock or an auto - what voltage does CPUz read when the CPU is under load?

This is an automatic clock, I used the MSI OC genie and it clocks it to 4.0ghz.

I'll try to reseat the cooler see if that makes any difference.

What are your load temps and what does the Core voltage read in CPUz under load.

Keep in mind that auto clocks usually pump in more vCore than is actually required for a stable clock - sometimes considerably too much. So it's worth checking what it's set at so you can get an idea if temps are relevent to the voltage.

How did you apply your paste and how much?

Wepohn · 23 Nov 2011 at 14:13

I'm also using the stock cooler and running the cpu at stock speeds but my idle temps are around 48-53

I thought this was a little high but I jus' figured it was the stock cooler. I find the stock coolers really tricky to mount but I thought I'd done it properly. Guess I'll give it another shot.

Nice tidy build that

How about the Antec Kúhler H2O http://www.overclockers.co.uk/showproduct.php?prodid=HS-005-AN&groupid=701&catid=57&subcat=1395

I'll run a load test now and let you know.

I applied a bead somewhere between a rice grain and a pea. Then I used a plastic bag around my finger to gentle rub it over the cpu before slotting the heatsink in place.

Nothing wrong with that method and it sounds as though you applied the right amount - so it's looking like the HS, for whatever reason, hasn't made full contact with the CPU. Or it has but not enough pressure is being applied - make sure that the screws are fully tightened.

bainbridge · 23 Nov 2011 at 21:35

I bought the Corsair A50 for £30 odd as OCUK were bundling it with their 4.6Ghz set.

Did exactly that with very little effort, idling around 37c maxing to 70c in prime, 58 ish during gaming.

There are better coolers out there but at the moment this is more than adequate.

Edit to add: tinted both surfaces with ICD then a pea-sized blob.

I used the same method the first time I ever seated my stock AMD heatsink on my 9850BE and I've been getting high temps. Then tried the same amount with the (it'll spread itself) approach and got no difference in the slightest. As for the pressure, it's definied by clips so can't really tighten it anymore. Any ideas other than having it as a very funky ornament?

What are your load and idle temps and is your chip clocked?

There's a chance that the clips aren't exerting enough pressure from the HS to the CPU. Something on the Heatsink's frame may be 'giving' too much so that not enough contact is being made.

If your temps are unreasonably high i would buy a budget 3rd party cooler - the Hyper 212 Plus is ~£16 and will make a massive difference to your temps. If you want to spend a little more then the Gelid Tranquillo ~£25 is worth considering.

Load test very quickly put temps at over 70 degrees so I turned it off as I didnt want to fry my cpu, but it seems the OC genie on the MSI Board is overclocking more than 4.0ghz, it put it straight up to 4.6ghz when I started running Prime95 torture test.

I'll tighten the screws more on the heatsink and see what happens, I was careful in tightening the screws as I didnt want to damage the cpu or any pins. So potentially to careful.

They should come to a natural stopping point - where you can't turn the screw any more. The HS basically determines the amount of pressure applied.

Make sure you tighten each screw a bit at a time - tighten one a little then the one diagonally opposite and so on until all four screws cannot be turned anymore. This ensures an even fit all the way round - basically don't tighten one screw all the way and then move onto the next one - do a bit at time working your way round..
