i5-2500K

What frequency should I expect to get this processor to? I'm going to buy a new HSF since I'm using the stock right now. Basically the thing runs 4.2GHz no problem already and I can't imagine what it will do with more cooling.

4.5 seems average.

4.4-4.6 is the average. Most people can set the multi to 44x and get 4.4 without any other alterations. You can get to 5.0 with a little more complex alterations to the BIOS on many chips, but as always, YMMV.

Man, 5GHz...

I have lived through such a large frequency change

I think the computer I personally started with was a 5mhz processor (8088)!

I don't think that is true. I had to go up to 1.35, just to get 4.4 stable, and it won't even post at 5 ghz at that vcore. I know ymmv, just the norm is 4.4-4.6 but always with vcore, and 5 is only good for suicide runs. The one guy here that got 5, had to back it down for 24/7, and he didn't do much stability testing.

Curious, what CPU cooler do you have? I have an incoming 2600K along with a Noctua NH-D14. I am hoping for a 24/7 stable 4.5Ghz.

I have a Notua DH-D14 and 2600k with a Asus P8P67 board and able to get a stable 4.5GHZ overclock. I just changed the multiplier to 45 and left everything as auto.

Monitoring the voltage under load (Prime95 run) shows around 1.30 volts, but it does shoot up to 1.35v now and then.

The overclock was very easy....... so I tried 4.8GHZ and windows would hang etc (with manual upping of the voltage to 1.375v) and at the end of the day I couldn't be bothered trying to squeeze another 100MHZ+ out.

Well, I need 1.35v for 4.4 at all, at least that's what the auto setting grants in terms of voltages. I don't think I've ever seen a report where a SB user could not hit 4.4.

I can get to 5ghz with 1.375v, but there are significant changes to other settings to do so. http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4

Plus, this forum is far more conservative than, say, overclock.net. There's a number of 5ghz users there.

My 2500k is humming along at 4.4 with 1.28 v. I was higher initially on auto (4.5) but my volts went as high as 1.38 so I decided to back down and leave the volts locked at 1.28.

The big thing for me is temps. Right now I'm sitting at ~32-34c idle, 58-60c gaming (BC2), and 65-67c benching (OCCT) which is ok with me, for now. Once the summer hits and my office temp climbs another 10-20 F I'm worried that my cpu temps will get too warm when gaming. I'll know more when I replace the mobo with the fixed version in a few months. That will give me the chances to replace my TIM and maybe even my case since I'm ready to move on from this P180.

The newer Gigabyte and Asus BIOSes have an option called "Enable Internal PLL Overvoltage." You should be able to squeeze a bit more out of the 2500K if you enable this feature.

Not just that. Throw in way better IPC, SIMD extensions, ondie memory controllers, among other advancements. No contest

I have 2500K 4.5GHz at 1.35V.
I can run everything fine at 1.29V except Intel Burn Test (with AVX), and had to up the voltage all the way to 1.35 to stabilize it.
Can't really explain it because it was prime stable (both small and blend for over 24 hours).

 

[Zap]

What frequency should I expect to get this processor to?

It depends on what VCORE you are comfortable with running. The "conventional wisdom" says to keep it under 1.4v. Some have gotten chips that can go higher with lower voltage. I've tested mine (well, my wife's) and it can easily hit 4.8GHz, but at an uncomfortable-to-me VCORE.

I'm running 2500k @ 4.6ghz 1.345v 24/7 stable with a NH-D14.

 

[ssblood]

4.8 @ 1.392 IntelBurnText w/ AVX stable now.

 

[SlitheryDee]

I haven't really pushed to see how much I can get, but I'm stable at 4.2ghz with a -0.040 voltage offset. Any more voltage than that and temps get into the 70s in my HTPC case, but I could probably get higher clocks out of the same voltage setting. I'm not really interested in pushing my system to the edge of stability right now though. The thing is already 3x as fast as anything I've had before.
