Overclocking the i7 2600K - Voltage opinions

[dushvader]

Hello, have been using this processor for a year at stock speeds. Decided to overclock and got a stable 4.5GHz at an offset voltage of +0.025V on a Asus Sabertooth Z77 board.

Stock temperature is around 32-35 C ; When running Intel Burn Test at max stress; the temp shoots upto 75 C max. Air Cooling with a Noctua U12s push pull config (NF12 fans)

My concern is the max Vcore voltage of 1.384V which is displayed in HW Monitor

• The voltage value displayed at full load is 1.376V (using both CPU-Z and HW Monitor)
• The voltage value displayed at idle is 1.008V (using both CPU-Z and HW Monitor)

Is this voltage, ok for a 24/7 system? Does this have any adverse effect on the CPU?

Thanks,

I have been running a 2500k at about these voltages since it released. As long as your temps are ok, it should be fine.

Temps are ok i guess :

• 32-35 C (Idle)
• 68 C max (Full-Load)
• 75 C max (Intel Burn Test | Max Stress)

Looks pretty good.

absolutely safe / fine. I'd be concerned with 1.45-1.5 volts if temps were going over 90, but you are easily fine there.

My opinion: Sandy Bridge was pretty good for voltages shy of 1.4v under max load as long as the temps were under control... even more so if you weren't running it under some kind of super heavy load 24/7.

Try pushing it a bit further' as long as you don't go above 1.4V you will be fine. My 2600k ran for 2 years at 5 Ghz and around 1.4V.

Amazing that we have a new thread on this worn topic about an 8-year-old processor!

I did a lot of hairsplitting over my 2600K and 2700K. These are 32nm processors, like the Nehalem processors that preceded them. I think I'm on fairly solid ground for saying that the Nehalem was the last processor for which Intel published a "maximum safe voltage." As I remember, that spec was ~ 1.3875V. But since they arrived at that number in connection with a statistical distribution, you could probably take it over 1.40V and fail to see damage. A lot of folks were volting the Sandy as much as 1.44.

I stopped at volting them to 1.39V, and both systems continue to run tip-top at 4.7Ghz. But cooling is essential.

Have fun!

They are still solid performers, especially at 4.6-5 Ghz. Up until AMD shook things up with Ryzen/Threadripper, I personally had no desire to upgrade, and to this day I haven't been able to bring myself to sell the chip. IMO the Core 2 Quad Q6600 and the Core i7 2600k were both a gem of a release. Intel really hasn't pulled that kind of wow factor since then.

My 2550k ran at 5.6GHz 1.7v for a matter of minutes....Sure she was angry and cried rape but in the end she did the couple benchmarks I was going after. Not a real popular cpu....But I still hold the world frequency record for the 2550k....Beat out 12 other guys!

The suicide run didn't kill the chip. As far as I could tell it was one of those no harm, no foul, don't let it happen again things. As far as I know the chips still alive today.

Idontcare....(miss that guy around here) Once stated he pumped 2v's plus into one of his chips by accident once and it lived to see another day. Not sure what chip it was but thinking it was around that era.

@dushvader....Keep it cool and under 1.4v's and you should be ok.

Pretty normally for this CPU, don't worry. By the way, as temp voltage is all well.
