oc on 2600k with high temps

[radeoncali]

i used that guide on here to oc my 2600k chip and got i working ok but it gets supper hot with prime95 like 85c, thats with water cooling 1/2 lines setup
is this about right for temp? i seen it get to 85c and turn off prime95 and that was only like 30 to 40 sec in of running it, when im doing nothing cpu is about 40c

one more thing the vcore is at 1.520 with asus ai software i had it at 1.425 and prime would freeze instant this ok?
board is asus p8p67 deluxe b3

Your voltage seems high. Remember, the more voltage you give a processor, the hotter it gets.

Intel advises you not to go over 1.35v or 1.4v with the Vcore on a 45nm part.

Did you mean to say 32nm part? The SB procs are fabbed on a 32nm die. Just a tad concerned since the thinner the silicon, the less voltage and I'm at 1.32vcore now. I'm assuming you meant to say that 1.35 to 1.4 is for the 32nm procs.

85c seems warm for a custom water cooler with 1/2" lines. But it also depends on what ur running. You state 1.52v but give no speed. 4ghz? 5ghz? 10Ghz??!! At 1.5v+ I can easily believe you are running warm even with a good water cooling setup. Been there myself some tine back. Dangerden blocks with 1/2" custom setup. Then Pelts. Then phase change. Anyhoo.. give us a lil more info.

I would immediately drop your vcore. 1.5v is high enough that you can seriously degrade your chip long-term. If I were you I'd be shooting for max clockspeed at volts no higher than 1.35 or thereabouts since you need to take into account the risk/reward of running your CPU that high.. 4.8 is faster than 4.7, but I'm not trying to tear apart my transistors for the extra 100mhz.

most people don't go too far over 1.4 even for 45nm chips. my i7-950 is at 1.38 @ 4ghz. My 32nm westmere hex-core Xeon L5640's are at 1.35 vCore @ 3.6ghz and I wouldn't feel comfortable giving them much more than that

Wowzers! Yup, 1.5 vcore is way too much! If it takes that to stabilize an overclock, then don't do that overclock! Drop down a notch or two, it's not like your going to feel much difference.

I'm a little scared of my 1.425 as it is, but I've been up to 1.45 when I first went for 5Ghz. I've been able to shave some off since then by fiddling with Asus AI and playing with other voltages, 1.425 is prime95 stable for 5Ghz, but I kill of HT to keep prime95 temps below 80C.

To be honest with you, the ONLY reason I run at 5Ghz is vanity. I cannot bring myself to give up that sweet round number that I didn't expect to hit for years to come. But it's pure vanity, there's no feeling any difference between 4.6Ghz, 4.8Ghz, and 5Ghz in any game I play except my insanely heavily modded game of Civ 5, and that's such a minor difference as to be almost unworthy of mention.

Edit: Just realized my System Specs tab thingy wasn't properly updated, fixed.

What guide is that? I just bought one of these chips and am wondering about oc'n it.
Have a link to that guide?

Be careful following whatever guide he followed. He went WAY over the safe zone for vcore on his overclock. Highly recommended not to do that if you want an OC that is 8 hours Prime95 stable AND cool enough to be usable without throttling itself down.

All there is to it is, up the multiplier to 42 to start off at, that's the typical non-vcore needed starting point. Test that with Prime95 for a bit to be sure you're fine, and then bump up one multi to 43. Test it for stability, if it passes, go to 44. Rinse and repeat. If it fails, go to bios and set the vcore to 1.275 as a good starting vcore point. Stability test 43 at the new vcore. Try to only use 0.05 volt increases to improve stability each time you have to increase vcore, the less you can get away with, the less heat you'll be belting out. It's a delicate balancing act on this part.

The only 2 settings that are REALLY important is vcore and multiplier. Leave the bus speeds alone! And don't use the auto-overclock function built into ANY brand of motherboard, they all adjust bus speed as well as multi, and you don't want the bus jacked with if you want a max multi OC.

The only real secondary settings to worry about would be motherboard brand specific voltage regulation settings. Asus allows one to set the voltage regulation optimizations to one of 3 settings, the Intel power phase optimized setup, the Asus optimized power phase setup, and an Extreme power phase setup that enables all phases and keeps them on. I do have to use the Extreme setting to run 5Ghz CPU clocks, anything less and I hit a ceiling of 4.8Ghz Prime95 stable. Other brand mobos may label these settings differently, so some research on this part could help in your final OC maximum.
