I'm not a big overclocker but i have overclocked a cpu before, I'm just wondering should you overclock in stages to get the cpu used to different speed,voltage etc? Such as if my cpu is stock at say 3Ghz and I want to get to 4ghz, should you just jump right in and shoot for 4 or go for say 3.2 get it stable run it for a while then go for 3.4/6 etc etc
Will overclocking in increments help the cpu cope with a higher clock in the long run.
I just read through the oc master thread and couldnt see anything on this so i thought i might ask.
I'm bring this up because when I get my 950 i would like to try to oc to 3.8-4ghz stable

I say just go for 4Ghz. Just make sure you watch your temps. With a i7 you will be limited by temps way before voltages. If you really want high clocks turn off HT and see how high it will go. HT produces tons more heat and high clock speeds. My i7 860 runs about 10C cooler with HT turned off.

I give things time to gel out.
or run a benchmark prog that burns system in "prime"? I would give it a good 48 hour before doing stuff, at least.
Alright thanks, last time i used prime95 and ran it for a few hours cant remember how long to see if my clock ran stable.
Would it be possible to get to 4ghz with stock voltage or will i have to increase it? I can't find to manys people bios using the 950
You probably won't go past 3.6-3.8GHz stable with stock volts. What are you cooling the CPU with btw? That matters a lot regarding results.
I'm getting a Thermalright silver arrow
From what I've read its basically the best air cooler on the market.
As i dont have it yet i dont know the temp idle/load of the cpu at stock speeds
I don't use Prime95 anymore. I've found OCCT to work much better, and much faster: Download - OCCT Website english OCCT will usually error out in minutes if something is unstable instead of Prime taking hours. A 2 hour OCCT run is like a 4-5 hour Prime run according to most. It also gets my rig hotter than Prime does. Its also really nice how at the end of the tests it gives you charts tracking your temps for each core, and you voltages.
I've always heard that you should first do a quick threshold estimate (sorry, forgot how that's done), then step up the BLCK in increments until you reach instability, then back off a notch.
I've seen benches on the Silver Arrow and while it is one of the best air coolers, it does not win in all tests. The DH14 beats it in about half of them.
@Doc, Thanks for that OCCT link. That is just the type of tool I think I'd like to use. Prime95 seems outdated anymore.
All my parts are in, but I can't legally drive out to pick them up until Friday when I get my 1 day permit and get my state vehicle inspection done. UPS says my H50 should arrive Thursday. The store I'm getting most my parts from says they have a Zotac GTX580 they can sell for $540, but I'm going to wait until they get the EVGA and ASUS they're expecting, which may come by Dec 12th. I'm hoping they'll sell me the ASUS ENGTX580 for $510, and if it comes in by the 12th, it will be in time to return my GTS250 3 days before the rebate deadline.
If you want to stress test use Linx to do so. It puts all other stress testers to shame. But if you want to be safe for your 24/7 clocks just put it at 1.35v and turn off HT and you'll be 100% stable even if you have a bad chip your chip will have more than enough volts.
The only other settings you really need to set are your ram volts, and ram timings. Besides that everything should be good to go depending on how good your board is at setting the various settings on auto.

What i would do with a i7 is find your max BLCK first. I would lower the CPU multi and keep upping the BLCK as far as it will go with the max "safe" QPI volts (not sure what that is for 1366 chips). That way you will know what your BLCK can do for sure and leave it set, and then start upping the CPU multi. That way if anything becomes unstable you will know its the CPU needing more vcore. You really shouldn't need any extra Ram volts unless you've got some really crappy sticks. I would just leave it set at the normal 1.65v.
