hi all
i've made it!
http://server2.uploadit.org/files/ki...ez-yyyyyyy.JPG
no troubles at all. it was a little bit tricky but it is possible to do!
well now the default-v-core looks quiet well :)

tomorrow i'll go for the 27xx mhz i hope!
mfg and thx 4 advices! the razorblade was really helpfull!

that was a while ago.
also, here's what my core looks like now, after lapping it :D
http://www.freewebs.com/ozzimark/core.JPG
wow, how much did you take off? also, that origami swan on your desk, I have two. About three years apart. :)
why did u lap it, was there a scratch?
my core isn't very even, too.
but 2730mhz prime/pistable is okay.........i hope the cooler fully touches the DIE.
-_-

Nice one ozzimark, tht takes some balls
:D
My 2.7G chip has died after a bios flash and I have a new chip with me now, tis a 0502 BPMW one and is currently at a prime stable ceiling of 2650mhz with 1.73 volts, watercooled.
The temps are arnd 43-45C full load, and im thinking of taking the shim off again, only problem is if im unfortunate enuff to kill another CPU with bios flash I may be able to RMA it, by removing the shim I cant.
So the question is, (and I should know the answer too this) should I take the shim off this new CPU? Will the temp drops equte to an increase overclk.
I just wished amd had designed the shim to have gaps in the side, so tht the heat building up within the shim would have an outlet to escape!!! I also thought it may be possible to pass a tiny tube between the gap in the shim (yup as u peeps know there is a small gap in the center on one of the shims sides) so tht air may be passed down here cooling the core. Very difficult or improbable to do but would be an idea if someone had the right tools

eh, probably like 1/4 millimeter? not muchQuote:

disclaimer: if you do this too, don't be surprised if you kill your cpu. i was very lucky
That is what was a little startling was the color. Not that I knew if they were polished like an XP or not. I have seen pictures of what is inside of the chip, but do not know where all of the components are located in there. Like how far down, are they in the center or torward the bottom or layered throughout. I'm glad your works, have you been able to see any difference yet. This also brings up something I've thought about but never to the point of doing any research. Inside of a ram chip, what is in there? Is it just material or is there actual structured construction of columns and rows. All the legs on the sides, do they actually connect to a column? Is the chip separated into columns and rows or does the electrons just behave in a manner that keeps everything separated, stored, what determines the various rows?
so at the end i can#t report a huge gain of mhz!
now i'm able to clock 30mhz higher....not much but the temps/voltages dropped a lot!

I was able to get another 100 mhz with same volts and same temps. I should be able to get higher, with better cooling.

Ive gone and done something i said i wouldnt do and tht is take the shim off
:blink:
bye bye warrenty, 2.65ghz just was not stable enuff for my liking, temps were causing the CPU to crash, removing the shim has enabled me to run 2700mhz with 1.75volts, not quite prime95 stable, but seems stable enuff for all the other stress test programs and games.
My temps have also gone down in respect to clockspeed and voltage. I can am now running full load (S&M) 38C, prime dosent go over 37C, and all this with my fans at 5V
:)
I just wish AMD sold some chips without a shim, so we could still have the warrenty, hehehee, 100mhz extra is nothing to laugh at!!
Just hope i dont end up killing this chip inadvertedly, needs to tide me over until Venice, can then shift it ebay or online forum, i know there are peeps out there who would like a shimless CPU, even without warrenty

I left it off. My waterblock fits nicely on it. However, I sold that chip to a friend and when he brought his system to a shop to diagnose his mobo, the morons in there chipped the chip. Now it can only run stock :(
I am now running a 3200+ which does better than the 3000+ with the IHS off :) I would take it off for 2.8 GHz stable but I'll probably just go dual-core or Venice so I decided not to bother.
Ok..
Just read this whole thread and I think im taking my fx55 IHS off later..
I bought it from someone that has taken it off already and put it back on..
Right now im totally prime stable @ 275x10 with about 1.59vcore.. Temps are about 38c idle and 48-52c load running prime.. I can boot to windows alot higher (2900mhz or so.. but not totally stable.. ) 280x10 is stable with most benchies but not prime..
Im hoping for some more MHZ and mostly to lower the temps... I have a 3400 mobile on my 250gb with a slk948 also and im pretty confident in mounting the sink on it without issues since its basically the same size core and all..
Plus with the IHS off I can place my temp probe next to the core like im used to doing on my 3400m...
Well wish me luck and I'll post my results later as long as I dont chicken out..hehe..
edit..
Maybe I shouldnt have did a search about removing IHS's.... getting scared just thinking about it after reading some of the stories.. :eek:
Then again there was some success stories..
Whew.. Ok that was scary ..lol.. what a hell of a rush..hehe..
But its all working and im gona test it out tonight.. Ive been using MBM for temps and it seemed to already shave off about 5c and the AS5 isnt even broke in yet .. I also put a probe next to the core to test .. here are some pics.. :)

I would have shipped it with it off if oyu wanted it that way ;)
Looks to me it was on there DAMM GOOD from the way the cermaic is spread :)
Good luck with the clocking and just rem to "FILE" the socket where you see the
"SOCKET 939" down if your sink doenst make perfect die contact..
call me if you have any questions :) :woot: :woot:
nice, you planning on cleaning that up at all, kinda looks like poo but thats an aestitic issue not performance.
Hey dude ..Quote:

Still testing it.. I had a raptor that died a slow death and was giving me much instablity and I didnt know that was it. But so far 275x10 is totally stable with whatever I do.. Gona be testing with my bh5 and a higher multi this week..
edit..
I didnt bother cleaning it , maybe next time its off.. I was just happy it came off fine with no issues..Quote:

Are these cores made from the same material as the ones on mobile xp's. If so, without the IHS can they be handled treated the same. In other words no special precautions need to be taken as far as mounting water blocks and air coolers? I noticed a few post above someone mentioned chipping, and I did not know if these were more brittle/fragile.
you can use huge force as with reg mobile chips just go down strait not at an angle.. Ive used coolers that weight upwards of 8lbs "4x 7700cu zalmans for reference", lol..
its when you dont go down strait you chip/crush the cores :)
Hi guys ! I read the whole thread and seems that i didn't payed attention on wich boards people were succeeded to remove the IHS and installed their HSF.
Can anyone confirm it on DFI NF4 Ultra,D,DR boards?
And maybe someone had a luck to use the Zalman CNPS-7000B HSF after removing IHS ?
Tnx everyone !
if you are really worried about cracking/chipping the core just get some little sticky foam circles like the ones on the mobiles and put them on there. You can find them at any hardware store in the same section they sell cabinet hardware (knobs and handles and such)
Yup thats spot on, ive done exactly the same thing to my CPU and GPU :). Spongy material on each corner is the way to go, as well as along the small resistors, you dont want to damage thoseQuote:

Yup thats me.. :)Quote:

After some testing last night the temps are definitly better..
Before.. idle 38c load 48-52c
After ... idle 33c load 43-44c
Also with the probe i placed next to the core it reads 32c idle and 40-41c load..
So it was well worth it for the temps.. :)
Ive been using the 30min test in OCCT .. And before the highest I could pass it was at 275x10 with about 1.59vcore.. Now after this its passing at 280x10.. This is also the highest it will pass when not using a high htt also..
Before prime would also error out in 3-5 min's at 280x10.. But after this it ran 4 hours last night before an error.. I know Sandybeach..hehe.. im not being one of them running prime all the time..lol.. just wanted to see if this changed anything.. It does pass all 3dmarks at 280x10 with no crashes at all.
This weekend im gona finally install some games and see how she does at 280x10..
