What voltage are you running your CPU at?

[tolis626]

As the title says. What's your core voltage? Just curious to see what most people here are running. Feel free to post details.

0.680v idle / 0.996v load. i5-3570 OC'd to 4GHz. If I drop to stock 3.4GHz, I can get it to 0.888v load under Prime. I think that's towards the "rather good" end of the silicone lottery spectrum :biggrin:

 

[DominionSeraph]

It varies. Welcome to P states.

 

[Deders]

Set to 1.251 in the bios, reads as 1.272 in cpuz when idle, and 1.288 when under extreme load.

Yup, that's quite good. I think you're wasting this chip by not overclocking it high, but that's just me! It must run really cool though...

Well, I obviously meant what the voltage is under load, not at idle.

Well, it's a "vanilla" i5-3570 (non K), so the multiplier maxes out at 4.0-4.2GHz anyway (3.6-3.8GHz max Turbo Boost + 400mhz limited OC on Z boards). Temps are around 40-52c for gaming. Can't get it above 55c even under Prime (on a cheap Coolermaster 212 EVO with a silent 700rpm fan). I'm highly reluctant to upgrade to a Haswell because it's so damn efficient. Whole system power draw under 4T Prime is only 77-84w, so the CPU itself is effectively only pulling 50-55w or about the same as a stock i3.

"stock".

 

[Soccerman06]

1.4125v for an amazing 3.8ghz woooooh

 

[jkauff]

1.3v on my 4790K for 4.7ghz. Closed loop water cooling with double radiator; Handbrake temps seldom reach 80C.

 

[BTRY B 529th FA BN]

1.23v 4GHz, X5660, HT on, temps in the high 60s C, in 74*f ambient - Prime 95

 

[Techhog]

1.180V, 4670K, 4.2GHz. I can lower it, but I'm lazy.

I have two systems for reference, neither have a very good chip though; most people have better luck than these numbers. Using Anandtech's overclocking method:

i5-4670K 1.31v @ 4.3GHz
i5-4690K 1.3v @ 4.5GHz

Both have similar closed loop liquid cooling (Coolermaster Seidon 120XL, Corsair H70) applied with Arctic Silver 5.

The i5-4670K runs pretty hot. It spikes to 60C after a few minutes of load, but takes awhile to get above 70C. I've had it fail OCCT after a few hours when it hit 85C. Fortunately I never load it that heavy for long periods of time. It's a gaming PC and most games I play don't really tax the CPU.

The i5-4690K runs noticeably cooler at load and doesn't float temperatures as much. I've never gotten it over 70C, even running Prime95 overnight.

Am I the only one that is afraid of leaving my CPU running stress tests overnight? Not necessarily overnight, I'm just afraid of leaving it there running at 100% without my presence in case something goes wrong. I mean, during Prime95, my CPU produces enough heat to overwhelm my H110, so it will rise to over 90C (sometimes hitting 100C and throttling) after about 30 minutes of testing. OCCT/x264/AIDA64 are lighter on the thermals, but I'm still afraid to leave it.

Generally, my way of testing involves opening any monitoring software I need, starting the testing (usually OCCT because reasons), opening my music playlist and leaving it there. I don't watch it or do other things, but I know it crashed if the music stops playing. Not the best way to do it, but I am at peace knowing that if anything happens, I'll be there.

Am I too paranoid about it?

1.2v Bios 1.226 reported 4770K @ 4.8GHz, Corsair H100i, Gigabyte Z87X-OC. It does 5.1GHz @ 1.35v but I won't go above 1.25v for 24/7 use.

Interesting that you can get a Haswell to 4.8Ghz on 1.2v. My G3258 / H81M-DS2V combo tops out at 1.2v, and I can't even get to 4.0Ghz stable on my dual-core.

Sweet mother of god. I'd pay for a chip like that. You won big time in the silicon lottery dude.

 

[Bubbleawsome]

I've got 1.18 or 1.27 so that doesn't fit well.

 

[CropDuster]

1.20 under load, .9 at idle. X5650 @ 3.8ghz.

Went through 17 chips and de-lidded them all to get that chip, which is a Costa Rica 3313B414.

"stock".

Same. I really have no idea what it is for an i5-4690k with the "optimized" setting in an ASUS Z97-A BIOS. All I know is that it runs rings around the FX-6300 it replaces (that one I definitely knew the voltage of - overclocked the heck out of it).

 

[buklau]

0.8v idle 1.285v full load @ 4.6ghz 4690k

Chip is delid with MX-2, but still having heat issue during prime95.

 

[sm625]

I have it set to 1.3V but it spends most of its time at 1.05.

 

[ninaholic37]

0.988v always

 

[MongGrel]

1.44v on a X5650 @ 4.3 at 60C steady on air using Prime 95 blend.
