Overclocking: Intel i7 2600k [CPU] + P8P67-M Pro [Motherboard]

[Tevron]

I want to overclock the CPU to 4.4ghz. Give GTA V and other games the push . Its at stock at the moment and i was wondering if anyone has any advice on how to get that clock speed?

Specs:
Windows 7 Ulitmate 64BIt
Intel i7 2600k 3.4Ghz
AMD R9 380 Nitro
OCz 8GB 1333Mhz Ram
OCz 750 Watts power supply
Noctua NH-D15 Heatsink
7 Corsair fans
1TB Hardrive

Might have missed some bs out of the specs. If anyone can hook me up on this, that would be cool.

Increase the multiplier for the CPU.

ill be honest it depends on the chip i generally say if you have time to spare bump up the clock speed like .1ghz and run a test for 30 mins if stable bump it up another .1ghz when its not longer stable bump up the voltage and run another test if you are in a massive rush you can try to bump up the voltage by .2 and the cpu up 1ghz and see if its stable and then slowly increase it if it's stable and temps are okay until you hit your mark but there's always that chance you lost the silicon lottery and have a bad chip that cant get to 4.4ghz and keep it stable without being forced to bump the voltage to unsafe levels

Thank you guys, ill look into it now and get back to you.

yeah just increase the multiplier you can prolly get to 3.8-3.9 (maybe a bit higher) without adding any voltage then go up by .1v no need to go above 1.35v to achieve good results from 1.2ish stock.. dont adjust bsclk

You should be able to push it to 4.Ghz without rasing the voltage. I am running the 2600K @ 4 Ghz on stock voltages and air cooled. Been for over a year now. The processor can hanle it. The main thing to worry about is whether your memory can. That is where you will get allot of protection faults, is where you push the memory buss too far and it chokes.

the memory bus will only go up if you increase the bsclk changing he multiplier wont increase memory speed

That is dependant on the motherboard properties, which we do not know as of yet. Play it safe.

Ive got it to 4.4Ghz and did a 1 hour 1/2 stress test on the overclock and it passed. I did put the voltage to 1.4V. I dont know if I should lower it. Ive played a good few hours with need for speed and I can see a difference in game when it comes to fps. What worries me is, will it maintain?

bsclk is tied to fsb,memory,pcie etc multiplier has nothing to do with memory speed two ways of increasing memory speed 1. increase xmp profile 2.increase bsclk

thats not bad 1.4 is ok i would personally try lowering it to 1.35-1.375... 1.4v is kinda high for 4.4ghz then test again if you lower it

I did what you said, put it down to 1.35 and did a 6-7 Hour stress test and it passed. Haven't tried any games with it yet. Currently away for a few days

Yeah, you basically have the same problem I have now as far as performance goes. Sandybridge does not support PCIe 3.0 and your video card does, so that will limit video bandwidth to 2.0 PCIe spec. Which is fine but you you may run into trouble when moving to higher resolutions or mutli-monitor setups. I was using the P8Z68 Pro model motherboard, swapped it out for an ASrock, but the PCIe spec is holding me back to 2.0 compliments of Miss Sandy. But I will be upgrading to a new system in about a month or two. The 2600K has been rock solid for going on six years now so I can not complain.

This article on PCIe versions is worth reading. Live benchmarks on youtube show the same thing.

Thanks, that was in deed informative. But then; that is really the question with patrons like the OP and myself over long term. Stay with a single card single monitor setup, or jump on the wagon and stretch resolutions to 1440 -3990k, large curved single panoramic screens or two monitor or three monitor setups. Witch brings this all together one year after upgrade do you add a card and go SLI/Xfire? In which case at that point might as well add another monitor, or switch to a larger panoramic one, since a single card can do 1080p no problem. But games and developers are finally starting to play with environments, adding more particles, tesselation, shadows, more reflective surfaces and lighting. Its not all about vertices and and polygons now.

Trying to piece together a system for a 5+year run now is not as simple as getting a new vid card in a couple years. I myself was disheartened when my monitor gave up the ghost and I had to get a new one. The only ones I could find in my price range were wide screen 720p, or 1080p.Which required me to upgrade my video card. Untill that point I was was happy as can be running everything in my arsenal maxed out at 1200x1600 4|3. Now Im at 16|9 1080p and games like Tom Clancy's division are chugging my system. Forcing me to reduce to medium. (Yuck). Serioulsy try finding a good LCD 20" flatscreen 4|3 today that is not specialized for a certain industry, thus raking up the price.

And VR is comming. Right now the recommended specs for a VR system seem kinda high, compared to a Sandybridge setup. I might go with the VR, but for now I will wait and see. Mostly because I wear corrective lenses (perscription glasses), and want the first commercial phase to run its course so we can identify and deal with issues with headaches, epilepsy, dizzines and what not; especially since like most wearer of glasses each eye is a different perscription and you can get dizzy or dissoriented in many kinds of situations.

Yes this is true. And you seem quite knowledgeable on the subject, but bandwidth is the limiting factor here. He has a 4 GB card (or 2GB), with a SandyBridge. Pushing Sandy's clock is only going to get you so far. Seriously if he wants a another years performance he is better off swapping the 1333 memory for some 2133 and running it at XMP 1.3. This way he can increase the buss and clock Miss sandy at 4~4.2GHz, all on stock settings. Since he is limited on the number of lanes. The only option is to increase the speed at which those lanes are used.

Having a 2~4GB card is nice in photoshop, or modeling, but real time action? You need to move that data from A to B and that requires either # of Lanes or Speed, or Both.
