How high can i5 2500K can be overclock?

[aqe040466]

I have an i5 2500K CPU running at 4.7 GHZ clock speed. How high can I overclock this CPU? I want more juice out of it.

depends on your cooler, mobo and how lucky your cpu is.

Can you list your cooler, current voltage, temps on prime95 and mobo?

Don't expect much more than 4.7 for a 24/7 stable oc, though.

Currently this are the settings:
CPU: i5 2500K (overclock at 4.7 GHZ) Vcore is 1.43 V
MB: Biostar TZ68A+RCH
TEMP AT IDLE: 34-38 C
TEMP AT PRIME95 8HRS: 45-57 C
MEMORY: G-Skill Ripjaws X series PC12800 (1600 MHZ)
CPU COOLER: Cooler Master Hyper 212 PLUS
PC CASE: Cooler Master HAF 932 Advance Edition(Full tower ATX)

I hope you can give a reliable answer or explanation,

Thanks

no one here is going to recommend a higher voltage than that. Actually most people will recommend lower voltage. Ultimately it's up to you though, depends on how long you want it to last and how

that said, your temps don't sound right... I have the same cooler and my temps are quite a bit higher, even at a much lower voltage and in a push/pull config. Is that voltage reading from cpuz or bios? The cpuz one (on and off load) would be useful.

I'll find you some mobo specific stuff when i get home tonight.

Those Temps are from CPU-Z, HW Monitor, I can say those temps are low because, my PC case have a lot of ventillations and air coming in and out of the case and to mention that I have touch screen fan controllers that can control 5 fans, It got 3x(200mm) fan, 2X(120mm) CPU fan push and pull configuration and 1x(140mm) fan.

Thanks again.

You do realize that any higher is strickly for bragging rights as you will not really see the diff.
Say you get to 5.0, from 4.7 that is only a 6 % increase, and that is only for the CPU, system performance increase is MUCH smaller.
I think the threshold for noticing an increase is 10->15%.

Your Vcore is already above the recommended max of 1.40 (Yes you are below the max intel spec of 1.50)

You did take advantage of the Intel's $25 OC No-questions-asked warantee??

My i5 2500k runs at a 5.0ghz overclock on an Asus P8Z68-V pro/gen3 mobo with a Corsair H100 exhausting out the top of my CoolerMaster HAF-X Case.

I am LinX, Prime95 and IBT stable at 1.35 Vcore.

My Idle temps are around 30C and my load temps are around 68-70C.

With more cooling, we could go higher, but to what end?

1) That voltage would bother me. Heck, 1.400 bothers me. From what I've read, most of the PC community regards 1.38-1.4 as the ceiling you don't really want to exceed if you plan on keeping it longer than 6 months.
2) When you look at your temps, make sure you are looking at a log over time. If you run a stress test and just stare at a moving number, you are only looking at the temperature that's true when the PC slowed down enough to display that temp. When I was starting out I was thrilled that I never saw a temp over 40c. Then when I ran a log and saw the graph I saw that it was peaking at 62c.

Does nobody else see the issue here?

The Hyper 212 + cant produce temps like that

57C @ 4.7Ghz 1.43v?

You're looking the CPU temp (the temp of the heatspreader)

Check the temperatures of the individual cores (Download CoreTemp)

 

[slicedtoad]

^yeah, i've been thinking something was wrong. My hyper 212 + with two fans and with my mobo on my desk doesn't stay that cool. And I'm at 1.35vcore.

Soon I'll have my water loop set up though. Then I'm ignoring vcore limits and only watching temps. If it breaks, i'll buy another one.

can you tell me what the rest of your bios settings were with this OC? if you still have it that is

Smell That?

Sniff, Sniff?

Smells like there's a couple of piles of BS lurking in this thread! :lol:

At the OP, RetiredChief has given you some excellent advice, I'm glad you realized it by selecting his answer as best solution.

I'd like to add by telling you that most running the 2500K are running theirs around 4.5ghz usually around 1.325v, because 4.5ghz seems to be the performance sweet spot for most 2500Ks.

For daily 24/7 running, Lower voltage = lower temperatures = longer lasting

As long as you are air cooling think about being satisfied with 4.5ghz for longevity.
