opty 146 ihs or no ish

well guys mounting an opty 146 in my rig currently has the ihs loose on the cpu. Will i see any benefit from removing the IHS in terms of temps/clocking ability?

yes and yes

Yes have a look at this

I take all my A64 IHSs off now, no messing around

Actually was browsing net, and found out that Opty's are the best CPU's to remove IHS, as the contact between cooler or something is bad, just google it

Yeah, also Google where some folks slice off the components underneath !

well opterons tend to run hotter than the equivalent 939 chips that's for sure.

no-one really knows why but they are server class chips so they're probably binned which is why they clock so damn well.

although my recent batch 4000+ runs much hotter than any other 939 chip i've had including opterons so there's always exceptions.

hey i knocked off 2 caps removing the ihs on my opty 148 ....still clocked to 3.4 just like it did before removal haha

when i had a 146, with ihs it would do 2.9ghz, but when i removed it i could only get it to 2.8ghz. Had no idea why, temps were the same, if not a degree lower without the ihs :confused:

Did you damage any of the tiny resistors?

mounting is extremely important once the IHS is removed, there's no way possible your o/c will be lower all things being equal.

so my money would be on a mounting issue.

I've read on a different forum that AMD started soldering the IHS to the chip so if you try to remove it then you will most probably damage the chip. I've seen a picture of this happen to some dude.

Not that im aware of

And surely if it was a mounting issue them my temps would have been higher :confused:

Anyway it dont matter now, all in the past

I think thats with skt AM2 cpu's, skt 939 are still made the 'good 'ol way'
