Lapped my XP120, threw it back on the Opteron 165

[Max0r]

Before I start off I want to thank Sneaky for his help over IM. He's like the old school mafia boss of lapping.

Full load before/after in celsius (case config, air flow, ambient temps same (hot))
Core0: 62/54 -8
Core1: 70/67 -3
Mobo CPU sensor: 46/40 -6

Wondering if I should lap the IHS. Too scared to bring damage with the violent XP120 mounting process to remove it.


-=Before=-

-=After=-

-=Starting out... needed 150 grit then 220 for nickel removal and overall flatenning=-

-=Nickel removed=-

-=Finished... grid paper test=-

-=Screen door test=-

-=Ocforums reflection=-

-=Anyone recognize the reflection? =-

-=As you can see, far from perfect finish. D'oh!=-

Thanks for stopping by. Think I should lap the opty IHS now?

nice job!! i have one question. did u use a flat surface to put the sand paper on or did u do it by hand?
n/e way nice o/c as well

 

[Max0r]

Thank you! I used the piece of glass that came with the lapping kit from easypckits.

I c you have a similar oc. What voltage you runnin it at?

I would cut off the IHS personally. I didn't say that, though... may not be worth the risk. The 120 is a very strong/heavy mount.

my old xp 120 looks sexier than ever lol

 

[Max0r]

See aren't you glad you sold it to me???? ^_^

I think it could be possible to mount the XP120 on the bare die without a problem... especially with some pads. The worst part of the mounting process is when you've already hooked it on 1 side and you're bringing it down, because part of the base lands on the edge of the proc and then as you keep pushing the HS down flat from the tilt, the base rubs hard against the edge of the proc.

what final grit did you use?

 

[Max0r]

The final paper I used was labelled as 10 micron.

stock volts , i lapped my storm block but i did it by hand and am regreating it lol i guess i should pull it of and do it again the right way
micron snading paper is nice but i used a liquid sand papper at 10,000 grit

ziggo0 and Deathman have done it, I lack the courage and I never take my IHS off anyway.

Stock you *******. Dude I tried using that 10,000 grit final polish compound but I think I just ****ed it up so I stopped usin it and just used the final paper in the kit.

I think the IHS thing could be done with the xp120 if I use the proper padding devices. I theeeeeeeeeenk. Whether or not I'm actually considering doing it... I'd be surprised if I did, but then again... for some reason I just can't seem to decide definately not to.

pop that damn ihs off that thing!!!! lol... i have a SI-120 sittin on my naked p4 3.0c... without pads and with no probs.

 

[Max0r]

^_^ The crazy thing is I'm actually considering removing the IHS

The SI-120 mount is the exact same procedure as the XP-120 isn't it?!?!?! You know what for some reason I'm feeling extremely confident in the idea of removing the IHS!!!

it is very easy to take it off. But best thing i have found for a blade to use is the razor in a disposable razor (bic) cause the bluse is so thin then i put soem black tape on the blade to make it easyer to hold + to stop the blade from going in to far.
As far as mounting it is a bit of a pain I tryed once with my xp-90 I didnt liek it so i toosed it under water.

3200+ Winny


That chip since i removed the ihs is a rockin chip it does 10x270 1.55v @ 30deg load

 

[Max0r]

Well that's about it man. I'm gonna do it. I'm gonna do it right now. I'm guessin I'm gonna have to **** with the XP-120 mounting bracket. Either way I'll test contact before I power on. In fact I'll set voltage to default and underclock before I take the CPU out

Any info on the XP120 bracket will be appreciated.. links or otherwise

 

[Max0r]

IHS off and she runnin! I'll start a new thread with results as soon as I fix mounting issues. MUHAHAHAHAHA

Here is a tip if your going to pop off the IHS and use the XP120.

After you've mounted the XP120 so many times the retention clips become much more...umm...easier to push down. Thusly meaning it doesn't take all to much effort to get the heatsink on there without one side flying up or it sliding to one edge.

I removed the IHS off my Opty 144 and pealed off the 4 round squishy things from a dead 2600+ and set them gently on my Opty 144. GENTLY sat the XP120 down on top of it. Applied direct downward force onto the center of the XP120 (where the fins are), and used a pair of needle nose plyers to put the retention clips down. Pending how much work you're XP120 has gone through, knowing it was Rattles', should be pretty broken in by now. You don't have to apply to much downward force, but just enough so it doesn't move side to side.

I've recently killed a 3700+ mounting my waterblock. I slipped and it shifted to a side chipping the die. Now, don't let that worry you, I was mounting it in a VERY SMALL mATX CASE! Not much room to work with...I've also mounted the XP120 on my Opty 144 (currently both pieces of hardware reside in my friends rig) without the squishy pads, but I don't recommend it if you're not confident in your own ability - just yet =). Feel free to add me on MSN or shoot me a PM if you need any help mounting it or even removing the IHS, they aren't as fragile as they appear!

what are temps like after the IHS removal?

Isn't that before the IHS removal and after the lapping job on the XP-120?
