lol???
why do you recommend not going past 4.0ghz if its possible and easily achieved?? especially with a Noctua NH-D14

And yea.........i know the performance of the cards, a 5970 absolutely wrecks a GTX 295 in every situation, GTX 295 doesn't come close

For the same reason I would not recommend putting nitros oxide on a car... You may get the speed you need, but you wear out the processor faster. Unless you are the type to upgrade every 2 years. Overclocking severely decreases the life of your processor. It is the reason why overclocking voids warranties.

2.6 to 4-0 is a pretty excessive overclock. You would be pushing your luck after that.


Where are you getting your information from? Fermi isnt out yet. They can not do testing on cards that have not been released yet.

EDIT: oh and lets not turn this into a Nvidia vs ati discussion. I go where the power is, and currently the 5970 is the king. I am just saying wait for fermi before you make your decision.
 
I say OC it until it melts. Never fun to just let it run stock. I'm probably killing my Xeon with over a 70% OC but it's just fun to do it and for many applications besides gaming it's quite worth it. I've never used an i7 yet but if the old kentsfield Xeon can pull that kind of an OC then I imagine with a good chip you can pull off some pretty awesome numbers.

P.S. 2.6 to 4.0 is only a 58% OC, that's really not that bad.
 
Well if you are willing, and have the money, to replace computer parts every 1-2 years then by all means. Overclock that thing till the solid capacitors pop. Show the world your 30,000 3d mark 06 score. (Anyone who even comes close to that score is either insane... or a genius.)

Just trying to say that OCing is going to cut the life of the processor in half or worse. But meh, to each his own.
 
I OC'd my E6600 from 2.4Ghz to 3.2Ghz. It was 100% rock solid for the full 3 years it was in service, and it wasn't showing signs of going bad anytime soon.

I honestly have no problem with OCing processors. As long as you don't push it to the point where it's getting up near the thermal limit, you should be fine. On the flipside of that, I refuse to Overclock video cards. They put out too much heat to begin with, and overclocking them puts even more stress on the chip and memory. My 8800 GTX died way too quickly due to overlocking.

To each their own, but Processor overclocking is fairly safe as long as you don't push it to the thermal edge of its limits.
 
my i7 920 C0 @ 3.8ghz requires quite a bit of voltage at 1.4 in bios ( 1.37 windows ) and while stressing can get as high as 76c while stressing with IBT. With everyday use such as gaming i see about 66c . Intels spec sheet reads Thermal spec at 67.9c and Voltage range upto 1.375 . Really, as long as you are below 68c, your cpu should live a long healthy life. My CPU may have a lowered life expectancy if i stress test too much but should be ok using it regularly . Just a note, @ 3.6ghz , i need 1.28vcore and @ 4.0 i need 1.5vcore + and 1.5qpi + which gets pretty toasty...

Overall, excellent processor . I came close to going with a Q9000 series and am very very glad i didnt make that mistake. Best processor you can get at the moment around $200 .

Yea yours needs a lot of voltage to just reach 4.0..........is it a C0 stepping??

Anyway, even if i overclock past 4.0ghz it will definitely wear the CPU down but not that much.......if you read on the web, they say even if you OC you only lose like 3 years out of it. The CPU will last a long time when not overclocked, they estimate like 10 years or more. They say Overclocking only bumps you down to like ~6 years of life.

As long as you overclock with a reasonable Vcore and temps, there is nothing to really worry about..........the only CPU that would last like 2 years after overclocking is one that you run with LN2 or something everyday and push voltages to an insane amount, like 1.6vcore on the i7 920 would kill it.

It's actually fairly easy to get over 4.0ghz with an i7 920 D0 stepping, and if its from a decent batch. Your only main problem is temps but mine will be fine with the Noctua NH-D14, best air cooler on the market.

As for FERMI, they released some benchmarks on it already.........only Far Cry 2 and Dark Void (i think thats the name). The fastest Fermi gets like 80 FPS average on Far Cry 2 while the 5970 gets like 100FPS average on Far Cry 2. I forgot the number for Dark Void but the 5970 beats it again by like 25 FPS or around that. The Fermi is faster than a 5870 no doubt, by like 20 FPS but its still gonna be slower than a 5970 while costing just as much. They expect it to go for like $600.
 
Yea shes a C0 alright . Funny thing is i can take it to 3.6 ghz with only 1.23 vcore and temps on IBT will not cross 61c, but the 3.8 is more demanding and 4.0 is a pain.

I used to be @ tweaktown alot ( they deal with Gigabyte board support/ forums)and know of countless people using a D0 at or above 4 ghz with voltages around 1.2 - 1.25 easily. I use the U12p and it cools very very nice, definitely considering the D14. truly a monster .

There was supposedly a not so great batch of D0's produced in Sep-Oct but cannot say how true it really is.

Could u please post a link to that Fermi info Pew?
 
According to Intel, if you want your CPU(i7 920) to last at least three years of constant use(100%, 24/7), you should not exceed ~1.35v CPU VTT and not exceed ~1.375v CPU Core.

I'm not too worried about high overclocks. I tend to upgrade my entire rig every 2 years.

lol well i know i wont be running constant 24/7

the max vcore i would use is probably like ~1.4 a bit more or less.

Here is a link for Fermi - http://www.nordichardware.com/news,10580.html

There is a thread on it by FreakingHell with some other links.

I also heard about a some bad D0 steppings, not terrible but not like the other ones.........mine was made recently in November
