Removing the A64 IHS

I've got a picture of E4 FX.

Comparing in this post.

Well... I removed it. And I chipped 3 resistors. No PCB scratches, and no Core damage.

And it still works. OMG

And stable too. No drop in temp yet, but thats A) Because I need to remount the Zalman CNPS7000 better. B) AS5 hasnt 'settled' in yet.

[Jumba]

Just removed mine on my E3 Venice 3000+, ah nothing beats a nakkid CPU. After remounting my Koolance CPU-300 block (had to place a copper disc between it and the core because of the gap) load temps are down from 54 deg C at 300*9 to 40 deg C! Also, this has allowed me to reduce vcore down from 1.675V to 1.6V. AS5 is still settling so am hoping to get better than this. Overall, I'm very happy. As mentioned before, don't force the razor blade - take your time and everything will work out fine.

so, has anyone actually crushed a core yet? I really really want to take the plunge, i'm just scared because my water block mounting bracket does not have any springs. Right now i just tighten it down grdually with both screws until its snug and the block wont slide at all anymore. oh yes i;ve got a x2,3800. OR do you think the core is large enough that i dont really have to worry about crushing it?

Sure they have. And scratched the CPU out of existance. And bent the pins to hell.

do you think the core is large enough that i dont really have to worry about crushing it?

Sure you can crush it. If you don't want to worry about then leave the IHS on. This is xtremesystems We like to worry and crush cores heh

[ocZZ]

what type of glue can I use to reapply the IHS?

[Revv23]

im going to do this to my 2.8c, even with great contact, im seeing the temps shoot up 15c within 2-3seconds after starting prime...

ive always thought i had contact issues but with an xp-90 and an xp-120 i didnt see any improvement at all from the 120, its like the extra mass isnt there... got to be core to IHS contact.

[Mr. Tinker]

what type of glue can I use to reapply the IHS?

just plain 'ol Elmer's wood glue.










ok, seriously, you can use arctic silver thermal epoxy. But don't call it glue.

[Ref]

He probably wants to reapply it with the black thing AMD uses to "glue" IHS... what is that?

[Revv23]

i wouldnt use that as it looks like a goop, might hurt contact, honestly i would either use something like krazy glue or just nothing at all. good TIM contact would hold it in place pretty good imo.

[Ugly n Grey]

I used RV sealant, basically a silicone based product , just used a dab on the corners and clamped the IHS on.

[Revv23]

good call UnG

how come you put it back on?

[Ugly n Grey]

I put it back to stock cooling, reduced the voltage and set it to run 1.2Ghz at low volts with IHS on.

It was the Venice for my Dads HTPC, does 2.7 plus on air with IHS off and a BT. Higher for 3D benchies. Was easier to get the stock cooler to fit with IHS on. (when I say stock cooler, it's the stock cooler off a 4200 so it has two heatpipes).

Anyhow, it worked well, instead of AS5 I used really gooey white Antec stuff between the core and IHS. Worked just as well as it did before I took it off.

I got it off fine and haven't crushed my core, and dont think i really need to worry about it. I made some foam feet that compress to about .027" (fully compressed!!) and the core is about .034" tall. I;ve tightned my water block down pretty darn tight and pulled it off to see a nice grease spread pattern, so i;m no longer worried. It did drop my temps almost 8c at load. and now im prime and mostly super pi stable. i ran 2 instances of super pi and 2 instances of prime 95 and 1 super pi failed, but the other 3 did fine.

[Darkenreaper57]

Will a stock cooler from a retail venice make proper contact once the IHS is removed?

I want to remove the IHS on my opteron 146 :P. My main worries are bending pins or cutting through the PCB by accident...

[k3n.chu]

also, how thin shoudl the razor blade be? i already scratched the pcb board and it still works =P

edit: i am also using an xacto knife.

[Darkenreaper57]

I came across this article http://www.overclockers.com/tips1197/

Has anyone noticed this issue, particularly with a d-tek whitewater?

I'd love to pop the lid on my cpu, but this makes me somewhat hesitant. I suppose I could always sand down the cam, but I would be afraid of cutting through and damaging the lever mechanism.

[Zebo]

This is definity scary. I would prolly need about 60 stiches after I cut myself. One question though. Should you leave processor in board while doing this so no pins get bent and acts as sorta a "vice" to handle processor a little better? I really big like 13 ring size and could palm a basketball at like 14.. not very nimble person.

[Revv23]

good luck working a razor around the proc socket, all those nice caps to rip off.

better off just holding it and being careful imo.

use the sponge that came with the cpu and then put that on something spongy, the pins will go into the cpu pad and won't move at all. of course, that doesn't stop u from cutting into the pcb, ehhehe.

I'll compare the pics in this post.

E3 Venice
E6 Venice
E4 SanDiego
E4 FX
E4 Manchester
E6 Toledo



Die Size
E3 Venice = E6 Venice < E4 SanDiego = E4 FX < E4 Manchester < E6 Toledo

Now, I need pics of E6 Manchester and E6 SanDiego.

hi.. e6 venice update

[kocsonya]

e6 manchester updete...

e6 manchaster = e6 toledo!! (2*512kb cahce)

[Enz0]

Thank you very much, kocsonya.
I've updated the post.

so i have been reading a couple places. i really want to learn how to remove the ihs for a while. from what i read throughout many forums. i realized that removing the ihs is easy and piece of cake as long as i have the right tools such as the blade and the right thermal compounf i should be set to go.
as of right now i have a 4400+ and it's not overclcoking well with high temps. so i decided to take a risk of either selling the 4400+ for a low price or something or remove the ihs. i'm leaning toward the ihs side right now since i haven't got any offers yet.
the only problem that i'm having right now is how to put on the xp90c that i have onto a dfi mobo without crushing the core on the 4400+ after remova of the ihs. from what i know the xp90c is hell of a lot heavier to put on then other hs.
also i heard that you can put on the heatsink attached to the retention bracket and then screw it on to the backplate as a form of a bolt on. i was wondering if this effective. also is there a way for me to do this? is there pictures? do i need foam on the other side of the cpu?fplease fill me in with all the information you have about putting on a xp90c. thanks

Alright guys I'm currently doing this as I type this to my opty 146 (on a second pc, obviously :P) and I'm really nervous. I taped off roughly 3mm on the blade. I've seen some black foamy stuff come off, but i haven't really pushed too hardm, afraid i'll hit something. How deep should I cut in on these opty's? If I dont cut deep enough I'll never get it off, but I just cant figure out how much I need to do it.
