2500k Overclocking (How much VCORE ?)

Hello there,

So i have posted a few threads regarding this topic, however it's seem my poor wording of questions lead to confusing answers. So here's my final thread on this topic.

RIG:

CPU: 2500K
GPU: GIGABYTE 7870
CASE: COOLERMASTER 690
PSU: COOLERMASTER GX 600W
RAM: CORSAIR 8 GB 1600Mhz
COOLER: COOLERMASTER 612S

I was wondering what sort of voltage i'd be able to get way with considering the following stock temps of my 2500k.

IDLE: 20c-30c 😎 (Ambient is unstable)
PRIME95: SMALL FFTS - 50c
GAMING: 42c
RENDERING:47c

Note: I'm not asking Intels' max specified vcore is ? But rather the vcore i should be able to get with 80- temps.

Thanks for reading, looking forward to your responses,

- Jack
 
Your question is kinda confusing?

You'll need to first overclock to see what your temps are gonna be....So start the adventure already 🙂

Try around 44x and see how much vcore you need....Guessing around 1.3v's
 
I also have an i5 2500K. I have it at 4.5GHz at 1.275v. It's stable as hell. I can get up to 5GHz but I need 1.45v and this is too much and doesn't really make any difference in gaming or benchmarks.

Wow ! You got your self a 2500k Overclocking GEM ! :biggrin:
 
@Kenmitch

I meant with temps such as the ones i've given, how much vcore should i be able to cool. Whilst staying under 80c. Thanks for your input though

I understand the temps part....It's the end results that aren't predictable without at least trying that is the confusing part. You need to just start your overclocking adventure and see were your cooler ends it.

i've seen as high as 1.4v for everyday, stay below that and you should be fine (actually 1.45, but to be safe, you know)

this does NOT apply for ivy bridge chips, just sandy

really? my 2600k with HT on does 4.6ghz at 1.275

Since I can't read minds or know what testing regimen other posters used before declaring "Stable!" I won't question the numbers. I will say that my 2600K @ 4.6 Ghz with HT needs about 1.32+V under IBT and Prime load conditions (and PRIME may show the lowest load voltage). But there were some fine voltage-increase adjustments I made so that maximum GFLOPS and narrow variation or greatest consistency would show in IBT or LinX.

Depending on my LLC setting, this means an idle peak-speed voltage can be as low as 1.35V and as high as 1.37 or even 1.38V. I choose an LLC setting that still shows about 0.02V of vDroop.

There wouldn't be an HT option with a 2500K, so I'm guessing that a similar optimum could be found with slightly lower voltage range.
