i7-2600K at 4.80 GHz with 1.450V - OK?

post #1 of 22
Thread Starter 
Earlier today I decided I wanted more than 4.50 GHz out of this CPU. I was further encouraged by the fact my brother overclocked his i5-2500K to 4.80 GHz!

I've now got mine running at 4.80 GHz (100.0 x 48) in Turbo with 1.450V CPU voltage as set in the BIOS. LLC is at Ultra High. At idle, the voltage reported by CPU-Z is 1.456V and at full load, the voltage reported by CPU-Z is 1.440V / 1.448V (jumps around these two a bit). My maximum temperature is 74°C and on one of the four cores - the rest are a tiny bit cooler. HyperThreading is enabled and I want to keep it enabled.

Would you say this is ok for 24/7 use?
Mind you, this 4.80 GHz business is on Turbo Mode - when on my desktop, most of the time it runs at 1.60 GHz as you no doubt know.

No, its not OK.
If you were on water it would be still pushing it.
Anyways why do you want 4.8GHz? You won't see difference between 4.5 and 4.8 while 4.5 needs much lesser voltage.
Anyways 1.425V for air, 1.45V for water.

Really?
I was told 1.500V would be the maximum to stick to...

I don't think they will mind if you buy a new processor soon either!

Its user preference, but I saw a lot of people here on OC.net said that 1.425V for air coolers and 1.45V-1.5V for water coolers. Keep in mind its 32nm chip and putting that much voltage trough little chip is a bit pushing it.
Intel maybe stated 1.55V as max, but Iv yet to see anyone running it 24/7 on that volts.

There's quite a few people over here running similar voltages. At least that's what they overclocked to.

Besides, my temperatures are alright. I never get 74°C unless I'm rendering intensely in 3ds Max. Air cooling or water cooling, a voltage is a voltage. If 1.500V is fine with water cooling, no reason why it would not be fine with air cooling as long as temperature is fine.

Well, they mostly got over 5GHz at those higher voltages.
I just think its not worth for 4.8GHz, you wont see difference between 4.8 and 4.5, play safe. If you really want 4.8GHz then go for it.

That's a fine max temp. The voltage is a much higher than I'd like to see just for that speed though.

That's just me though. However, since 74 isn't extreme, I can't tell you NOT to run it at that speed but I'd personally feel more comfortable at a lower vcore for 24/7 use.

how long did you pass prime 95 with these settings? and yes those voltages are perfectly fine. What the person above fails to realize, is that it does not matter if your are air cooling or water cooling in this case. All that matters is that your stable and your temperatures are safe. The point at which it becomes time to switch to liquid cooling or any other cooling method is when you reach your safe thermal limit of your current cooling system and can not go any further.
