Removing the A64 IHS

Got myself a 3000+ S939 2 days ago, cooled it with a DD TDX block. At 290X9, 2.61Ghz, 1.68v (cpu-z), the full load temp was 55 degrees. After I removed the IHS, the full load temp shot up towards 80 degrees! Tried resetting the block a few times but keep getting sucky temps.

After that I applied some AS5 onto the core, popped back on the IHS (didn't glue it, just place it back on the proc), the full load temp dropped 3 degrees! Before Prime would fail in 90 minutes but today passed 12 hours at the same speed and settings!

Will try to fiddle again with a naked proc and the block when I have the time.

i think i might try it this weekend but im a bit scared about my hs not fitting

That I find to be odd? Not to doubt your finding's, it's just that the TDX has a verty small foot-print, and i've found it to be ideally suited for processor's with their IHS's removed. In fact I feel the AMD A64 IHS is so massive (larger then the PIV) that the TDX isn't the best block for the job. I bet you can see the edges of the IHS protruding from beneath the edges of the TDX. And remember that "cup" impingement zone only occupies about 25% of the total block's chamber. You were using through-board mounting correct? It seems as if something either prevented the TDX from making proper contact, amost as f there were stand-offs or something? I don't know what the S-939 socket looks like close-up, but I belaive most DD blocks rely on through-board mounting. Your not using mounting hardware which clamps down into the plastic retention bracket are you? What may happen is that the chip's core simply doesn't extrude high enough to clear the socket. Then the TDX would be tightend down onto the socket, and not so much the CPU. It may even be compressing the thermal paste, tricking you into believing it's making contact with the processor. Can you take a close up photo at an angle of the CPU locked into the socket with out it's IHS? This would give an indication if it's not high enough withot it's IHS to make full contact with the block.

i removed the ihs of my pentium 3 tualatin 1.3ghz 2 weeks ago :D

all i can say is:

STAY AWAY FROM RAZOR BLADES!
they only scratch the package and bend and break off etc etc... only caused troubles for me.

go to a farmacy and ask for a scalpel :)
that should do the job perfectly :)

/joke mode on

Perhaps it should be made clear which type of razor....

This...http://www.premiumknives.com/knifefi..._198_small.jpg is wrong

These... http://www.americancuttingedge.com/A...e%20Blades.JPG Are right!

/joke mode off

:p:

for me a razor blade worked bad... my scalpel worked perfectly... maybe the razor blade i used was too thin, it was bending all the time..

I just removed my IHS, it is fairly easy with a raror blade. The temp drop between 4-10 Degrees.

anyone want to sell me thier ICh that they ripped off thier cpu? im in need of one....

thx perc,

Well this can only get better.

Exactly what I was hoping to find under there. :)
Unfortunately I won't have any results real quick. Still have to mod the prommie bracket and well, tomorrow is football day you know. I will post back to give my results in a couple days though when I have it done.

Perc, if I'm happy with the results, I'll shoot you a pm to get your address so I can send you my spreader. Your shared experience with the topless chip/DFI LP UT/prommie bracket mod will save me a lot of time in shaving bracket, checking contact. At least now I can shave it pretty close before I take a fit check. :toast:

Well, it'd be great to tell you how well this all worked out, but my freakin' LP UT died on me. After all that work. I thought it must be the chip, or even though it looked like good evap contact, maybe that, but nope, it's the board. In my troubleshooting I put the spreader back on, used the retail cooler, switched to my 8KDA3J, and booted fine. Went back to the DFI, nothing. No idea wtf, but don't even get to post. Tried 1 RAM stick, clear CMOS, etc. Since I hate the Epox, and won't spend for another s754 board at this point in time, I guess my upgrade to s939 just got bumped up a few months. I'd love to give a temp compare after getting those bubbles under the IHS gone, but all my baseline temps were taken off the DFI board, although IIRC, even with the spreader back on, I'm around 10C cooler then I remember on the Epox. 3700+ already spoken for by a friend, with only air, but I'll post back if he gets any more out of it then I could on air.

Hey guys, this is my first post, and I'm in need of some help. I removed the IHS and figured out that the heatsink doesnt make contact with the heatsink. So I go ahead and silicone the IHS back up with the processor, just to find out that I have killed my cpu. I need to know what was that black rubbery stuff AMD used to glue the IHS to the processor, so I can RMA it. Thanks.

Shouldn't you just throw it away since you killed it?

Hi. i received today my A64 3500+ " NewCastle", cananyone tell me if he is good for OC or should i make a change?

if its 939 then get a winchester! if its 754 then keep it... maybe test it first and sell it if you dont like it.

well i think its good overclocker.. i have now 2700MHz :)

DUDE!! that is exactly what happen to me with this dammed DTR3400 and DFI mb! i had shaved the bracket down like i showed you and was 100% sure i had great contact but after like a day or two of running it like that i was in the bios and was setting some memory timmings i hit exit and save and poof nothing never booted again??? im just now getting the dran dfi back from rma and man wtf? that is why i needed a ICh cause im not going thru this again. fugger was kind enough to send me one he had ripped off his 2800 chip so now i have it all glued on my 3400DTR chip and im ready to try this again :) we should make a thread called "putting the ICh back on :) "

peace perc,

yes, thats a very good ocer :)

My Newcastle can only run 2.4 Ghz @ 1.7V. Temps are like 43 degrees load with uber watercooling. Worth taking it off?

i (tried) to read every post/page but havent seen anything on any winchester IHS's...
anybody tried on a 3500+ (939) winnie yet?

i know, i know:
(NO Joe, why dont YOU try it and tell us :stick: )

My co-worker at Legit Reviews has reviewed this CPU recently; http://www.legitreviews.com/article.php?aid=118

I actually gave it some thought when I was plugging my 939 back into my Neo2 this morning. I'll probably do it when I pick up a new heatsink next week.

cool :cool:

i was just thinking that this new 90nm core might be a little easier to dammage than the monster sized 130nm 64 cores...but then agan we've worked with similar (sized) cores all this time and you dont hear about A LOT of chipped/cracked pallys, Tbreds or Bartons.

GOOD LUCK conrad.maranan

Tried on my 3200 and got a degree extra so far.
