I want to overclock my CPU which is an 17 2600 not the 2600k
1. is it possible?
2. if so where can i learn how
3. i am doing a software overclock i guess. any good software?
4. Not sure if my PC can handle the overclock as far as cooling

More about : 2600

If you do not have a "K" cpu, you can not change the multiplier.

You may have limited capability of changing the bclk from 100 to 103 or so, but it is not worth it.

If you have a p67 or Z68 motherboard you can overclock a K.
It would be worth it to you to trade the 2600 for a 2500K, assuming that you do not run heavily multi threaded apps.

Sandy bridge runs cool. The stock cooler may get loud, but it is adequate.

the answer you were given was absolutely completely WRONG. he could not have given a more wrong answer. you can overclock that cpu is looks like to 4.1 ghz.

the multiplier is not locked it is just limited to how high you can set it.

sorry geofelt for calling you out on this but your just wrong.

I ran Intel's auto tune on my intel i72600 (NOT K) and also on my second i72600K, both in a intel DP67BG motherboard and both auto overclocked to 4.16ghz.
Tested with Prime95 both ran flat out all 8 threads at 78 to 82C with an uprated cooler. The stock intel cooler ran at 92 to 96C which is too hot for my liking.

Yes, geofelt is wrong, locked multiplier doesn't mean you can't change it, it means you're locked to a maximum. And in this case the 2600 max multiplier is 42 which is 4.2ghz on a single core (3.9ghz on all cores) as you will be limited by turbo. This is because OC a non-k is actually adjusting the turbo settings.

It is the same as overclocking a k version cpu, but not all mobos allow OC. There's a sticky guide in the top of this forum. If you have the stock cooler, it will only handle stock speeds, but pretty much every aftermarket cooler is better and can handle these mild OCs.

82* IS WAY TO HOT FOR 4.16. if you have an aftermarket cooler you did something wrong installing it or it just plain sucks. i never hit 73*+ with my 2600k at 4.6 so something is wrong.

I think what you are seeing is the bclk overclock which can go from 100 to perhaps as high as 106 or so. That is a 6% improvement.
when applied to the 1 core turbo of 3.7, you can actually get one core near that 4.1 number.
All 4 cores are limited to 3.8 The chart is an excerpt from the anandtech sandy bridge preview. It was not the result of any testing by anandtech.
http://www.anandtech.com/show/4083/the-sandy-bridge-rev...

I also wonder about the source of the chart, and what the "1" note on the slide means.I suspect it means exotic cooling since 5.7 is an unusually high overclock.
You can overclock the graphics part, but that is largely useless on a gaming rig with a discrete graphics card.

Some usere have reported that their motherboard allowed a 2600 to specify multipliers greater than stock without error.
But... the multiplier was not actually used.

Being open minded, I would like to see some non photoshopped reports of high multipliers for non "K" chips.
Perhaps it would be best to open a new thread on this.

now your just beyond wrong. its nothing that intel has really"done" is a mobo manufacturer work around. you can overclock a 2600 past 4.0 and if you disagree, have fun being wrong.

If you don’t buy a K-series chip and instead grab a Core i7-2600, Core i5-2500, -2400, or -2300 (along with a P67-based motherboard), you’ll still have access to “limited unlocking.” This basically means you can set clock rates up to four speed bins above the highest Turbo Boost frequency setting available at any given level of processor activity.

So, take a Core i7-2600 as an example. The chip’s base clock is 3.3 GHz. With four cores active, it gets one bin worth of additional performance—3.4 GHz. Four bins above that would be 3.8 GHz. With two cores active, Turbo Boost bumps it up two bins, to 3.5 GHz. Limited overclocking makes 3.9 GHz available in that case. In a best-case scenario, only one core is active. Turbo Boost adds four bins of frequency, yielding 3.7 GHz, and Intel’s overclocking scheme lets you run at up to 4.1 GHz.


Straight out of the tom's SB review, though there's a typo, it's supposed to be 4.2ghz. http://www.tomshardware.com/reviews/sandy-bridge-core-i... Similar is said in the anandtech article. Bunch of threads on this forum of people doing it.

If you need cpuz validation you can google that as well.

Dropping the temperature by over 10C was a decent improvement in my view. Also I only get these high temperatures when testing with Prime95. No game can come close so far. Try Prime95 and let me know if you see a rise, if you don't then I will look for a better cooler. I appreciate your advice and experience, Thanks.

i have run prime95 so many times and 73* is about the max i see with a hyper 212+ at 4.6 ghz.

Sorry, my dogsh*t isp is running the flakiest network in the world.

I tried to reply: I am using an "Arctic Cooling Freezer 7 Pro Rev.2 CPU Cooler " which is a lot cheaper than the 212+. I will strip it and re-apply and see if it improves. If not I will try a hyper 212+. Many thanks for your advice.

The 212+ is better than the freezer 7 but I don't think you should upgrade for only a couple degrees. As long as you don't go higher than about 72C at normal operation, you're fine. Depending on where you live, you could find better coolers than the 212+ at a lower price, if you really want to upgrade.

wow sorry about selecting the run best answer. anyway i dont really wanna overclock my cpu as i dont believe i have enough power to give to the system for that. 460w PSU with a GTX 560 is streesful enough. plus i dont think dell put in any significant cooler for 2600. it isnt the stock fan though.
