S939 A64 IHS Removal

you know the thread idea... what about cheese wire? if you mounted it on a Jr hacksaw i'm pretty sure it's be a pretty dam good tool for IHS removal... anyone know where i can get some cheese wire from?

they were at MOST 48, but usually around 47ish. idle temps were slightly lower too. could it be air flow in the case? - but if it were that then surely the temps would be the same.

*sniff* is my zalman faulty?

thanks

Nah, that sounds ok, just sounds as if the IHS was making good contact in the first place. The slight difference in temps is probably down to slightly different ambient temps.

ah i want better temps damnit! oh well, what is the max temp i should let it get to?

thanks

I've started using this program here. It appears to give a slightly more conservative figure than the ones found on AMDs website, but given the inaccuracies in temperature measurement that can only be good thing.

ah yes i've used that and it said 57. so im guessing that is tops then

cheers for all your help

I know at least one guy over at XS has removed his IHS with cheese wire. Reportedly it took a while, but it would reduce the risk of cutting any traces.

just destroy an old razor blade (the shaver kind) and take the thin flimsy blade wrap some selotape around one end and cut away - i used it and it was brilliant. a perfect cut if i may say so. at first i was scared to use a razor blade but it was so flimsy and was so easy that in the end i wondered why i hadn't started with it!!

I'm beginning to build up a collection of IHS's

daven1986 · 23 Jan 2006 at 17:44

im going to make mine into a keyring

Just to report:

Removed mine last night with a very similar knife to Jokester's.

Temps weren't bad before - 37'C load @ ~ 2.8 Ghz and 1.5v

Load temps dropped to 31'C after IHS removal.

Didn't help me overclock any further though

jimbo, even with more vcore?

Yup.

I've found these 90nm CPUs don't clock any better after ~ 1.6v. (I've had 3 or 4 3000+ Venices and now this 144 Opty).

It does 2.7 Ghz on default volts, then needs 1.425v to do 2.8 Ghz, then 1.50v for 2.9 Ghz. After that, it's tough going to get to 2.95 Ghz. It stops booting after 1.65v

EDIT - Nice system you got there! (VERY similar to mine, including 22" CRT

)

I was reading that you can use a liquid called Solvoplast to remove the IHS :

yeah i agree, the opterons seem even more extreme, mine just hit a wall at 3.2gig and wont prime for longer than 3 hours thanks to the heat generated by the significant extra vcore to get it to that speed. I'm sure if I ditch the air cooling it will mange that stable but im happy with what its doing now.

yeah i got my my sb 22" a few months ago for just 30 pounds! people just dont want big crt's anymore. its a lovely monitor, could be a bit sharper txt wise but graphics are stunning.

pretty interesting, we have some of that in the families medi kit, its safe on skin but i wonder if its safe on cpu's epoxy covered surface.

was cleaning out my pc today so i thought i'd take some pics.

OPTERON 146 CABYE 0540 FPMW

here you go...

Pics taken on a k750i

Anyone looking to do this, Go for it, dropped my temps by 10*c Load

Hesky82 · 7 Feb 2006 at 05:39

Hi mate, I noticed you have a missing surface mounted component, I see the solder blobs but no ic, I assume it is working fine.

OV3RCLOCK3R · 7 Feb 2006 at 12:51

Hey mate, yes the cpu is working perfectly. The IC was there when i removed the IHS but while i was handling the cpu, it slipped out of hand and dropped on the table so that IC came off although its working perfectly, PHEWWWWWWWW!

Hesky82 · 7 Feb 2006 at 17:43

damn! amd cpus are robust!

juno_first · 19 Feb 2006 at 23:02

my cabwe 4400 is now running 5c cooler with the top off.
can't clock any higher though

had to use a razr blade then took 5 minutes.
now running 40c under load - wish my a8n sli prem could churn out > 1.50v
