Removing IHS from Opty???

So I am debating the removal of the IHS off of my Opty 148. I am wondering if doing so will allow me to reach higher (stable) clock speeds above my 2.8ghz that I've already achieved. Logically, I would think it would shave a few degrees off of my idle and load temps, which would help make it more stable at 2.9-3.0ghz. Right now I can boot at 2.9ghz, but it's totally not stable. Would removing the IHS make it more stable? I'm willing to try this if people think it will help temps, which will obviously help the overclock.

Lemme know your thoughts...
 
I would have to say "NO". The couple of degrees it will drop still wont benifit you to overcome the 2.9 - 3.0GHz barrier. I would still do it, just for the shear fact that it will drop your temps 4-5c.

Let's say the 4-5c degree drop is what I need to reach that stable 2.9ghz mark??? Hmmmm, very tempting just to try and see for sh!ts and giggles...
 
If your benchmarking, it may be worth it, if your real hardcore about it. If it's for gaming, you won't notice the difference from where your at now.

My 148 is nekkid.... dropped my temps ALOT (not just 4-5C). I had one of those Opty's where the IHS was (actually, the thermal paste between the core and IHS) not applied properly. Removed the IHS, applied ceramique between the core and IHS, and AS between the IHS and Zalman 9500. It made a world of difference, and did allow me to OC higher. I then removed the IHS completely, and noticed another drop in temps after *MY* fix (not as drastic as the temp difference from the first fix). That drop in temp (3C) didn't produce any higher overclocks. But the initial removal of the IHS (to replace the thermal compound between core and IHS) helped tremendously.

BTW... I practiced on my 3200 Venice before I attempted the Opty IHS removal.... I killed my 3200 :mad: Yes, yes yes.... removal of the IHS WILL void your warranty. Did you expect AMD to approve of this operation??? :D
 
I did it...

I was scared out of my mind, but it all came out good. Didn't really see a huge decrease in load temps, but my idle went down considerably.

Am I glad I did it. Yes
Would I do it again. Probably not.
 
Did it warrant a higher overclock? Like I said, if it would allow me to e stable at 2.9ghz rather than just bootable at 2.9ghz, I would consider it worthwhile... I guess there is no way to tell unless I actually try it, afterall the only thing I'll achieve through the post is speculation.


Did you guys have butterflies in your gut before doing it too? :)

I didn't gain any OC. I started mine about 11 at night and felt physically sick. About half way through, I was shaking so bad I just went to bed. I woke up the next morning and about a minute later had the thing off.
 
How in the hell do you remove the IHS anyway?

I saw someone mention a razor blade but none of the ones I can find seem thin enough for the job.
 
It depends on what cooling you're using. My 144 did 2.8GHz prime stable, but wouldn't hold 3GHz prime stable. SuperPI 32M yeah, but not prime. After I pulled the lid, it did over an hour (like 1 hour 20 mins?) Prime stable @ 3.15GHz, and it diddn't fail, I just stopped the test. However, I use water on my system, so direct die watercooling on a lidless Opteron does more than just "a few degrees". More around the lines of a 6C drop instantly, and the ability to handle higher temps much better.

As for cutting them off, you can use many things. I use double sided razor blades from a pharmacy myself.
