Removing the plate off K6-III CPU.

[The Coolest]

I want to remove the plate that is on that chip (here (http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_1260_1288,00.html) ), it seems to be glued, but I can't remove it, I know that its core is more sensitive but I want to see how it looks and the steppings... Could any1 give me any idias?

I tried puting a flat screwdriver betwin the chip and the plate but it didn't work...

Hello!
I have dune the same ting on my old K6-2 500 AFX. It is not so difficult. If you have an old socket 7 motherboard take it and place the cpu in it, then you take a weary thin razor blade and stick it under the corners and cut the corners loose from the cpu. That my take 30-60 minutes, it takes a wile. The glue is weary soft. When you have cut the corners loose from the cpu you can carefully twist the cap and bend it bit and it while pop of after a while. The cap is glued to the core whit the same grey glue as in the corners so there is no bigger risk in damaging the core but still be careful and take your time doing it. I don’t take any responsibility just so you know. You can also make your own fetes to it so you don’t cruse the core but make sure the core makes contact whit the heat sink and use thermal compound otherwise you while fry it.

Have you been a ble to overclock/cool the chip more effectively without that cover? I've got one of those old chips and I'd love to see what I can do with it..

Word of caution people! I've de-capped my K6-2 several months ago and I just want to say:

1) If you aren't careful when trying to remove it you could easily damage your chip.

2) The last person I recommended this to now has a nice new keychain fob. Maybe the chip blew for reasons other than removing the cap, I can't see how de-capping would destroy it unless the chip was gouged which it apparently wasn't. Nevertheless before removing the cap this person had a K6-3+ 450@616 and now he's got a piece of decoration.

I was abel to get it to 570 prity stabel and I was abel to boot in to windows at 600Mhz@2,8V but it wasent stabel. I have never been abel to run it at 570Mhz and never booted in to windows at 600Mhz. It whil defenetly run more stabel if you are going to overclock and cooler to.

<<<<<<I've got the new key chain.

No problem eobard, it was my own fault.

Removing the cap wasn't the reason for the CPU failure. I had this K6III 450+ running fine at 600MHz after removing the cover. I believe I got a bit aggressive with my voltage, I guess 2.5v was too much for this CPU (the "+" series default voltage is 2.0v). I also had to replace the power supply and it is very likely that this could have something to do with the failure

I was lucky enough to find a replacement CPU, a K6-2 450 bundled with an FIC 2013 motherboard for $49.99 (I think this combination is still available at Tiger Direct).

I got that system back up with the K6-2 on the original FIC VA503+. Although I haven't spent much time "tweaking" it, I don't expect results anywhere near what I got from the K6III. I currently have it at 550MHz and will leave well enough alone for the time being, I am keeping one eye open for a replacement K6III. For my next project I'm considering a new system based on a KT266A motherboard. But then again, I have an extra socket 7 motherboard now and it wouldn't take much to get another SETI box up and running.

By the way, the new K6-2 450 has a default voltage of 2.1v, I thought the K6-2's default was 2.4v.

I hoped to get the cap off so the CPU would get cooler and cooler looking... I just couldn't cut this darn thing off... That's so annoying :mad: !!!!
Would the freezer method help or am I wrong? Is there any other way to get the cap off instead of cutting the glue?

1) I hope not or my K6-2 is doomed. I tried 2.7v and was mostly stable but not enough so I jumped to 2.9, perhaps I should test 2.8 for a while.

2) The paperwork I got with my K6-2 (it was a box) says that most K6-2 & 3's were 2.2v but some of the 3's were 2.4v. I guess as they got close to the production run end they made a few tweaks to get them running cooler.

No ther is no other way that is any good. A razor blade and some time!

I used some lighter fluid on mine to take the cover off and it worked great!!

But I still cant get it over 500 stable:mad:

specs:
Asus P5a
K6-3 450 @ 500

The groove that runs around the edge of the cap seems to be a perfect starting point for a direct-die type watercooling setup... just seal something right on to the cap and pump water across it. Hmm... I just might have to try that sometime...

What's your voltage? When my K6-2 was at 550 I needed just 2.5v but going to 600 required a huge jump to 2.9v for stability. I backed down after I temporarily killed my Duron cause I wasn't willing to kill both systems. If you're willing to test the things abilities, and its not a "+" chip, I say try up to 2.7v, in small incraments.

Could you please tell me exactly what you did to remove it with the lighter fluid?
