Overclocking i5 2500k
 

I'm ready to overclock my i5 2500k cpu w/ asus p8p67 evo mobo, they got a few options, don't know where to start. Going to watch some youtube video but you guys have been so great thought I'd ask here.

Funny you post this now. I just rebooted my iMac after my first go at O/C:ing ever...in small 10Hz increments.
When I hit Apply the monitor showed blue/white stripes all over and computer locked. YIKES!!:o
I hardbooted and everything seems fine. *pheww* :-P

Well, learning by doing wrong. I'm not gonna stop. Computer is very cool on stock settings so gonna read in some more and then try again.
However, I will NOT touch the voltage, just core and mem clock.

Knowing I have perhaps 10 more frames luring in my card drives me.

...It will be interesting to see how far you get. I've read several times that the non-K models don't overclock that well. Prove 'em wrong. :)

It's got an unlocked multiplyer, so it really should be easy, but someone with the same chip is better qualified to advise you.
I'm just curious as to what cpu cooler you have, in case I too upgrade to a 2500k at some point.

I have the same MB and Proc, with an Artic cooling fan and use the included with motherboard software, AU SUite II, to overclock (when I remember that is!).

It automatically does it for you, one click and is apparently quite good according to those that know.

Ohh, I'm talking about the HD 6970M. Stockspeed is 680/900 and I can pop it up to 710/1000 without changing voltage. Fanspeeds are veeeerrryy low as standard but with smcFanControl I can bump em and then OC the 6970 for some extra frames. Just gotta figure out how. Using ATI Tray Tool.

I use my msi overclock, to do my i5 2500k:grin:

thanks for rubbing it in doc:cry::)

Jay, do some google searching for overclocking your particular board. The first issue you need to be sure of before you so anything is cooling.. a stock HSF will allow "some" overclocking, but not a lot. Read up before you do anything.. while you are using it it is burning in so there is no rush. Until you know what you are doing its not worth messing around..

I'm using a coolermaster n520 cpu cooler, it's got 4 heat pipes and 2 fans, I was looking in the bios and there are a bunch of auto buttons to choose from but not sure, I don't really want to mess with the voltage but that might change, hoping someone here who has this mobo could steer me in the right direction, off to google some more.

Best to use BIOS rather than the windows application since this often sets voltages higher than they need to be (more power, less lifespan). Try here for a good starting guide.

Most important settings are the core frequency (clock), multiplier and Vcore voltage. For the 2600k which is a very similar chip I started out by just increasing the clock to 45 (i.e. 4.5 with the multiplier left at stock 100x) and increasing the Vcore to 1.39. You can then increase the multiplier if you want and gradually decrease the Vcore until you are unstable.

Make sure you do some stress tests using prime95 or similar and keep an eye on your temperatures using CPUID HWMonitor or the mboard app. Also, note that the voltages specified in BIOS are often lower than appear in windows (e.g. in CPUID CPU-Z) due to vdroop. The value reported in windows is the 'real' one since this is the loaded voltage.

Maybe this will be helpful:

okay I overclocked using bios but under system it still says 3.3ghz, only in bios can I see, 4200 mhz turbo and 1600mhz memory, is this right? does it only overclock the turbo?

Most utilities arent reporting the Sandybridge temps/speeds etc properly yet .Dont worry youre running at high speed!

CPU-Z will report the correct clocks...just remember these chips downclock and reduce voltages when not stressed. So run something like OCCT or prime 95 and look at CPU-Z while stresstesting with the other tool(s).

Installed ai suite II from cd that came with mobo and it is showing 4200mhz with sim running. IL2 1946/ ROF running great now:grin:

How are the temps looking?

between 34 and 44 deg cel.

working on pics;)

34-44 il2 1946
34-52 ROF

What benefit to CLOD?
 

I intend to buy the 2500K, as it it recognized on a few sites as the best bang for the buck gaming CPU. But I've read somewhere on this site that overclocking them means not one twit to CLOD. Can someone direct me to some thread or related data that says different? I'm equally concerned to know if CLOD is now optimized to use all four cores efficiently. I've lost track of where the sim is in that area. Thanks for any input that can help me understand.
Flyby out

Hello, is if you well understand the Spanish, but you always have the option to use the translator you can suggest one page WEB where all are great overclockers and the community of ASUS, that if you always help if you have machine ASUS IE as your case is an ASUS MOTHER... really recommend it if you help make OVERCLOCKING in less than 4 or 5 days, also could help you I, but it is that my English is very bad and the translator not be if it could help you much... I be overclock very well...
in fact now I have my I7 950 working 4. 00GHz but as you say no is all English is using the traductor.los feel.


Try to do a post on this page that you stop you the link and tell them that you are talking and sure ANGLO which the moderator will help you know English...


Here the link to the website of ASUSXperts

I hope that you help...

Go to a proper hardware and tech site were you wont get bad advice, this forum imo is horrible for that.

I've got a i5 2400 in my iMac and when I fly I can see a clear difference in the workload of all four cores. To me it seems CLOD utilize all four cores.

On OC:ing; I overclocked my graphicscard from 680/900 to 800/1100 (not touching the voltage) and that gave me 3 more frames in Black Death.
Not what you're talking about but perhaps some kind of indication of...something. :-D
