So true. Some people can gain up to 15C by taking the IHS off. I knew one guy whose temps were HIGHER with the IHS off. It's like overclocking: YMMV.

I actually got higher temps as well after I took off the IHS. Problem is it was extremely hard to get a good mount with the 7000B. And the Venice core is so tiny.
The only benifit I got from taking off the IHS was I was able to hit 2.6ghz with only 1.45. Anything higher still isn't stable and it seems the more voltage I give it the more unstable it becomes.
vegitto you're lying, you're not even close to giving up masturbating 
, every day i realize the day you gave up masturbating...is TODAY
sorry to go a lil off topic there....but ill try it tonight!

Wow, you're the first to notice
. Good job .I didn't have a problem getting my 7000B on my IHS'less Opty 146. It isn't as secure as I would want it to be, but its making good contact with the core.
"Step 2: Reboot at a voltage at which Prime95/StressPrime2004/Stability testing tool of your choice fails within seconds. Literally seconds. "
So I should try something like... 1.25V @ stock speeds?
Opteron 144 stock volts are 1.45V btw.
Just wanting to know what I should shoot for.

I really doubt this works in the way you think it does, if anything it's just the thermal paste settling in properly. That effect is not only well established but makes sense in terms of physics, that the chip somehow gets used to lower voltages doesn't.
Go for whatever boots. If it's lower than stock and lower than the previous setting, and it boots, it'll work
.I don't think so. I mean, my Opteron wasn't stable at this voltage until I did this. And now it is
. Do the math .So you rann the CPU for 200 hours or so at stock settings before trying to undervolt it? That failed and so you tried again using this method and it worked?
I can do the mathematics, it's part of my course at univertisty. That's why i think you're wrong.

We'll see how well this works. Right now I'm in Windows with a voltage 1.425, 2.75 GHz. SP2004 fails within a SECOND for both first and second core. Gonna burn in now, we'll see what happens.

Its also a new CPU and the thermal paste needed to cure.
Or mabye you have one of those new smart Opterons with AI.
He may be full of crap - however, I'm giving it a try now. I froze at 2.75 GHz, but now at 2.7 GHz / 1.408-.1425V it's doing fine - I'm going to let it go overnight and then probably see how it turns out tomorrow...
well here are my results...i let it burn just for 6 hours. cuz i had stuff to do online ..anyways ...the less voltage i could be stable on my opteron 165 @ 2548 mhz was 1.47 after "burn-in" i can now be stable at 1.46. I dont know if its working, but im gonna let it run for 24 hours.

Doubting people isn't nice. Check the OP, I posted a 10h Prime-stable screenie at 0.976V. I could've done it for longer, but I didn't have enough time. Maybe I'll let it run on Monday, k?
Oh, you'll see, alright
.6h is too short. I'd reccommend 18h minimum.
Vegitto - I'm still letting it Burn in (it's been ~ 16 hours). It's probably fine if I do light work on the computer, right (i.e. post on the forums)? If not I guess I'll have to run it for a bunch later. Let me know what you think.
Yeah, yeah, sure, you can do whatever whilst burning in except rebooting. Don't expect games to run properly, though
.ok here are my results...i ran it for 24 hours . before burn in i could boot up and be stable at 2.5ghz at 1.47 nothing less or my machine wouldnt even start. so i saw this on the forums and was lke " Yea right" so i said what the hell. now my box is stable at 2.5ghz at 1.39!!!! i cant belive it. i thought this wasnt gonna work but i guess i was wrong. it might not work for everyone but its worth a try. im gonna go and burn in somemore ...ill post later THANKS VEGITTO!!!
I found out something. There's a lower bottom. I can't get it stable at 0.900V (mobo setting), although it WILL boot at that voltage. I'd say this'll work until about ~0.950 true volts.
what I'd like to see is after you get where you want to be, remove the HSF, clean the old paste off the IHS and HSF, re-apply TIM of your choice and see if it still works after reseating the HSF

LOL anyone care to try?
