it wasn't an LGA775 ZX... it was a Celly D 478... none the less it was soldered to the IHS...
basically i cut around the epoxy with a real thin razor blade... basically removing the black epoxy around it... that gave it a little play...

after that i took the cpu... put in in the mobo without the heatsink... basically ran it till she was nice and toasty... then i took a thin flat screwdriver... and stuck it in a corner... between the IHS and the PCB... and GENTLY inserted it... most screwdrivers progressivly get thicker (kinda like a V shape from the side...) the farther you insert them the farther the screwdriver... the farther the IHS and PCB get away from each other (it did make a noise when the solder seporate)... BUT dont sporate them any more than 1mm apart at a time.. put the CPU back in the board... fired it up to get hot again... do another corner...
basically i did that until i got all 4 corners raised up... then i put it back in... warmed it up real good and raised off the PCB... and simply twisted it off...

basically if it's not warmed up enough... you'll crack the die... dead CPU...
but if you get it off... all you've got to do is clear off the solder... that stuff you can scrape off with your fingernail if you'd like... till you get down to the die... then just make sure you get it all off

but yeah... i got it off my celly D... i've been meaning to take pics... just havn't got around to it...

Yeah I know you can pop the 478.s But I have not seen a naked lga775.

i tried this same thing with my P4 520 awhile back... basically the IHS of my Celly D is secured the EXACT same way... with solder... soooooo... i guess this same method would work for the LGA775's... it's just i screwed up my 520

i mean i know what i did wrong with my 520 about 8 months ago... when i put the screwdriver inbetween the PCB and the IHS... i thought it was just epoxied on... not soldered... epoxy pops off easily normally... solder on the other hand is MUCH harder...

basically i had the IHS and PCB about 4mm apart and i heard the DIE crack...

maybe if i can get my hands on another 775 i bet $100 i can get the IHS off without cracking the die :D

Wait wouldn't the lga bracket lock thing be higher than the CPU die with no IHS?

Yould have to put a shim like thing on the processor so when the lock bracket type thing comes done it would lock not just little it slid uselessly in it.

I think it would make an improvement but not a worthy one for the risk. I know my FX-57 I pretty much got no omprovement when removing it. Then again it was cold bugged and I was using LN2 so was able to hit optimum temps. ;)

I think it may be almost worth the experiment. You just gotta have a lathe take it off insanely slowly and very little at a time.

Ive had a video where they straighten p4 ihs with cnc-mill. It dropped temps few degrees if i remember correctly. I think mill would suit better for the job than lathe.

Never lathe a CPU. No good can come of it.

I use a die grinder before I'd use a lathe or mill ;)

07-16-2006, 12:23 PM

The heat generated by grinding or CNC'ing could be a problem. It would hard to find a way to mount it for precision cutting without causing damage.

07-16-2006, 01:07 PM

LGA775 IHS removal is no problem, just cut the RTV sealant stuff under the edges of the ihs and hold a small torch on the spreader for a few seconds while applying a light twisting pressure to the IHS and next thing you have a naked chip! Also, the solder that intel use to hold the ihs onto the core melts at around 98*c so the heat from the torch won't cause any damage if you aren't reckless.

07-16-2006, 07:48 PM

i saw someware someone used a cigarette lighter to heat the ihs and as long as the flame doesnt touch the chip youre fine, then use a soldering iron and solder wick to clean the solder up, then use the outer edge of the ihs as a shim and the rest as a keychain

07-28-2006, 10:39 AM

can't do it.
i tried once and CPU = died!!!!!!!!
it is totally different then AMD.....
core is like super glue with IHS

MeltedDuron

07-29-2006, 03:01 AM

very few chips are superglued... you probably didn't heat up the IHS enough.

dead conroe... try it with a working one! no risk - no fun! ;) :eek:

:nono: :nono: That would be wrong. Imagine if the IHS is secured in a different way and he'd kill a good Conroe CPU. Imagine the waste!! :D

Thrilla

07-29-2006, 07:56 AM

Why not hold the chip up side down in a liter of hot water. This way you can control the water temp, and have enough heat capacity to melt whatever solder is in there. Though you'll need steady hands, or risk using distilled water (my wc leaked and the distilled water didn't kill it, I didn't realize that till I saw water on the mobo haha.

07-29-2006, 08:05 AM

wasnt it about 70Â°C?? thought someone (bbmods??) postet it some time ago over at hwa)

:toast:

Yep BBmods got confirmation from intel that the solder melts at 77C The core can take upto 140C though so it's safe. Although the performance benefit of removing the IHS. over just lapping it is far out weighed by the risk for me. :toast:

07-29-2006, 01:38 PM

Just lap it man :)

Or you wanna try removing it on x6800? :D

08-08-2006, 10:11 PM

I did it with my Celeron D 341 before, I got the IHS off with the core still intact.
But I must have cut some traces on the chip with the razor blade I used because its dead now.
I now have a Celeron D keychain.

08-09-2006, 12:36 AM

When the contact between the ihs and the core is that good, removal will gain 0% higher clock's imho.

for the people who want it still, why not grid it off, take some time but the heatspreader is not that massive, maybe start with a file.

Actually it can. You need to heat it up to 77c and then you should be able to get it off.

MeltedDuron

08-09-2006, 04:25 PM

screw temps, you heat it up until its hot enough! shamino was too paranoid, holding a small butane torch or heat gun to the ihs with very gentle prying will get the ihs off no problem, as long as you dont heat it for too long and melt the solder on the other side of the die.

.sentinel

08-09-2006, 05:45 PM

I am just saying thats when it melts. The cores can take up to 140C.....

[XC] Lead Head

08-09-2006, 05:49 PM

shamino pried upwards, wich lifted the core off, if he had twisted, he would have had no prob

You can do it with a larger tipped soldering iron, I know this for a fact.

[XC] moddolicous

08-10-2006, 06:57 AM

How good a thermal paste can solder be?? I mean, I can almost completely say that there would have to be a decrease in temps if it was done right. How could there not?? Unless the solder is like >80% silver (which it cant if it melts @ 77c) then I think there would have to be a decrease in temps (unless the die is completely ragged and jagged or something).

Naked 631!
done with the torch method...
i took 4 razor blades in each corner...and placed it in a clamp suspended... I set it so the IHS was above the blades (so the cpu would drop when it let go)

i heated up the top until it just popped off

Not 100% sure if my cpu survived... but it sure looks like it...
i've got to get a memory stick soon to throw it in and see if she'll boot

prayin like hell that it does

hm, some people say it has indium solder, which may be true then. its melting point is a bit above 60c, cant remember now for sure ;)

well... i polished up the cpu abit...
i went to install my Scythe Ninja... and it's not making contact with the die...

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/DSCN0913.jpg
no not a kingston plug :p: (i dont think i even have any kingston sticks)

so definetly going to have to modify some coolers to go IHS less thats for sure
i think my old chilly1 tube might have cleared it... but i dont really think so...
so some modifications might be needed...

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/DSCN0914.jpg

so fun!
gonna break out the dremel and shave it down about 1mm all the way around the green and see if it'll make contact

would be nice if i had the proper equipment

tada!

looks like hell... but it's making contact...
now i just gotta lap the base of the heatsink with some 2000grit paper and i should have the best contact possible :toast:

would suck if this cpu was actually dead
i need to aquire some money to go pick up some new sticks...

i killed my D9's because my stupid multimeter wasn't reading properly

CrazyXP1700

08-11-2006, 03:20 PM

im gonna go and take some pics of how i actually heated up my 631... so you people can see... anyone brave enough should be using my method...
shimano's is horrible
he would have had better luck inverting his cpu so that the IHS was locked in the vice... and twisted the PCB when it was all warmed up... thats how i did my first successul IHS removal on my Celeron D

im tryin to get out and get a new memory stick from the local store (staples... and they have 512 sticks with D9's! not fattys though... their 1GB PNY looks to be fatty's though, but their under heatspreaders)
but my brother just stole my car (he blew up my jeep a few months ago too!)

go around the IHS with the razor blade... some cpu's have resistor banks (like my 805) so only go in around .5cm... you just want to get the RVT silicone off

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/Guide/DSCN0926.jpg

Put a razorblade in all 4 corners of the IHS...
now this is going to be used to do 2 things
1. it's going to suspend the PCB so that it will drop right out once the solder reaches it's melting point..
2. the razors are actually going to be applying all the pressure that you need to seporate the IHS from the PCB... so you shouldn't have to twist or apply any pressure to it... once it's warmed up... all the presure is just gonna shoot that CPU down... and the razors should be holding up the IHS still

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/Guide/DSCN0928.jpg

place the razors holding the CPU over a vice, or something so the cpu can drop freely... now you'll want to put some foam or something like that below because it will literally POP off!

Core 2 duo's may be a little tricky... basically you've got a couple of these you've got to pop... i think warming up faster would be the best option... that way one core doesn't pop before the other... circular motions around the IHS would be the most ideal, the heat should transfer throughout... but still a fration of a second later could send one core popping off while the other is still firmly attached... (i havn't done one yet!)

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/Guide/DSCN0929.jpg

I used a big ass propane torch, a fire maker, 4 razor blades, and a CPU to risk!

Core 2 Duos are real dualcore = Two cores, one die :)
Kentsfields are two C2D dies on one package. They may be tricky.

Good job XP, do you know if it's a working chip yet?

CrazyXP1700

08-11-2006, 06:08 PM

nope... im having the same problem with these new memory sticks as i did with the board after i did the volt mod... and (i think anyways, i fried out my fatty D9's)
the board isn't reading any voltages

i think im gonna have to go up to raleigh and stop by tiger direct in the next few days and get a board to slap it into... while i try and fix this one
i might get a 975X board if i can spring it... any donations would be appriciated :p:

ugh... im wore out by this stupid thing...
it's the same problem as before... so i think my cpu is fine...

I machined an Athlon down to get the IHS for a load tester I'm building and I found that the small piece of circuit board was not parallel with the face of the IHS or the chip. I was able to machine it off very slowly using a milling machine and a fly cutter, taking 0.001 inches per pass, until I had the chip exposed. The very next pass just shattered the chip. My point is that it could be done, but I don't know how you would get the chip flat in the vise if you have to hold it from the pin side, I held it from the IHS side which was flat.

Dude looking good CRazy! First time I've seen this done. Your method is a bit rogue, but I like the style.

CrazyXP1700

08-15-2006, 02:39 PM

from what i can tell... this is the most promising way possible... it makes the most sense aswell... it SHOULD be successful...

i mean it makes complete sense... with the razorblades under the IHS like that... it's putting enough pressure so when the solder melts, it's going to seportate itself... you dont have to worry about it overheating the core though cause once it's at that melting point... it's gonna pop right off... im a genius! :p:

lack of hardware kinda leaves me hangin though... i dont know if my board has gone out... or my cpu... (if it was my cpu... it could have been before i removed the IHS... cause i attempted removal because i was bored!)

i might try and get my asus to crank up again... i've got some business to take care of first... but hopefully i can take another crack at firing it up tonight

http://img.photobucket.com/albums/v320/CrazyXP1700/Computer%20Crap/IDIOThaha.jpg
thats my old 520 that i removed this IHS off over a year ago.. . (january 05 i believe)
with that chip... i was heating it up and prying it up one corner at at time... the razorblades is a much simpler method to say the least
needless to say... too much pressure on one side will crack the core... non the less i never heated up the core nearly hot enough

Qkjhfhaiguihfma

08-15-2006, 03:27 PM

love the filename on that one :D

you do have a sweet method there.

CrazyXP1700

08-15-2006, 05:49 PM

well i fired it up... and i got nothing...
im not getting any vcore readings out of my P5WD2... so that kinda makes me wonder

i even took the heatsink off and put my finger on the core... and it did nothing didn't get scorching hot real quick like my naked celly D did...

so that makes me wonder is it the board or the cpu...
id love to blame it on the board... cause i was adjusting my mods when it last messed up

now i've got to find someone who has a 775 board or cpu in my area to test things out...
(my local compy shop doesn't even sell LGA775 gear... like it's the dead socket :rolleyes: )

[XC]melymel

08-17-2006, 08:43 AM

from what i can tell... this is the most promising way possible... it makes the most sense aswell... it SHOULD be successful...

OK I gave into temptation and tried your method on my celeron D :p:.
50278
50280

My method was basically to cut around like a normal 939/754 IHS to cut the rubber stuff and then to wedge 2 blades under oposing corners of the cpu. I then thought how would be best to hold the cpu and how to heat it up, I eventually decided to hold one of the blades with a wet teatowel and heat the IHS with a lighter. I held the cpu upside down (pads up) and wore a fireproof glove while using the lighter and just kept heating it until it dropped off. The entire process took about 2 minutes, not including thinking time and I found it easier than 939/754 IHS' thanks to it having no smd's. It fits in the socket fine thanks to the way that the bracket dips in the middle although a bit of rubber or something may help hold it in better. The IHS also cleared the top of my bracket so that's fine too. I can not show you it working as I think the m-boards dead but it fails at error code "45" on my diagnostic card which is good as if it's a cpu fault it's code "00". :)

The next time I do it though I think It would be better to put something to catch the cpu with rather than just letting it drop to the floor :rolleyes: and it may also be usefull to have something you can use to quickly whipe the solder off the core because mines cooled down and is solid now :D :toast:

CrazyXP1700

08-17-2006, 10:22 AM

looks good...
not all cpu's are free of SMD's under the IHS... my smithfield core has them.... (i believe presler, smithfield, and kentsfield have them... possibly more)

clear off that left over solder and take a looksee (pics!!)

i used a guitar pic... or some kind of rounded plastic...
i just scraped it off until i got close to the bottom and had a thin layer of solder on there... (heck you can even use your fingernail) then i hit it up with a small amount of polish to clear everything else off and remove that last bit of solder

you need to find someone else with a board and check that cpu... (same here!)

Well I can give an update to mine, the cpu is dead :( but it was dead before I removed the IHS. I have tested it in a friends 925x board and had no go and 45 code still. Also you can remove the solder with your finger nail as crazyxp said so that's one problem solved. I'm trying to get another celery now and I will try again :toast:

here you go guys i tried it on a d830. It would have turned out ok if i knew there were SMD components under the IHS:D ohh well i will do it right next time if i decide to give it another go.

I just did this for :banana::banana::banana::banana:s and giggles i dont think removing the IHS will prove to be a worthy risk.

This is really promising, it basically shows that removing the IHS is almost as simple as with AMD correct?

Is it a worthy risk, I think it is, Intel CPU's do tend to get hot and with the recent complaints about concave and otherwise bent Conroe IHS's this might be a blessing.

And even though it didnt do much for the A64's I reamoved the IHS from I still did it anyway. :D

basically if you dont know... google the core name in google images... and there should be PR shot of the cpu without an IHS...

IT CAN BE DONE!!!

I went and put some tape on my CPU... to help hold it in place... and it booted!

my heatsink was making horrible contact so i modified it by grinding it lower... and i cracked the core while remounting it...

IT CAN BE DONE!

I have a couple of IHS-less northwoods, and I have made shims using this (http://www.usplastic.com/catalog/variant.asp?catalog%5Fname=usplastic&category%5Fname=68&product%5Fid=12070&variant%5Fid=50091). It seems to do the job.

Agreed, I was just told off on the intel thread because I just stated the risks involved cause there were like X new into overclocking people that were like "oh! It's easy, I'll do it!".

Posted on the ln2 forum, that's fine since there are more seasoned members here that already know the risks, no need to tell them. However, you see how many dead cpus have pilled up already :)

Either through cracked cores, damaged SMDs, etc.

All I was trying to say there was that although it is good, and "less risky than other methods" (no disagreements there), it still is not the best thing since sliced bread as it was portrayed to be ;)

Good luck with the next cpu though, I'd really like to see it working. Seasoned OCers will definately put it to good use under phase/LN2 :)

09-12-2006, 02:06 AM

Yes Gordon! The core can take more pressure than you think.. it's like a core of the old Amds... no problems. The only important thing is a cpu cooler with height adjustment -> screws and springs...

largon

09-12-2006, 07:01 AM

The chip is dead as a brick.
Oh well, it was useless with the IHS on anyways for the chip was priming at 75ÂºC (CoreTemp) with water cooling.

Absolutely horrible IHS-die contact it seems.

btw,
Don't even bother using a butane lighter for the heating.
I emptied the whole lighter but the damn plate didn't move at all, these things just don't seem to generate enough heat to melt the TIM.
I had 2 package knife blades stuffed under the opposite corners but they merely warped the PCB.

edit: Hmmm... How about an E6600 next...

largon

09-13-2006, 12:56 PM

I finally popped (literally) the IHS of the presumed dead chip...

I bought a new lighter, stuffed the blades under two of the corners and heated the IHS while holding the cpu upside down. Suddenly the (I)HS just took off with a bang.

The core is flawless. I thought I had actually cracked some corners or partially ripped the die off of the package.
There's a slight possibility that it's still alive but just refuses to post due to the extremely warped package causing improper contact with the socket. The cpu is now clamped in a screw press in order to straighten the package.

Update expected within 24 hours.

p.s.
I'd like to elaborate that no prying whatsoever is needed during the removal. Just cut the black silicone and heat the middle of the IHS with a lighter while holding the cpu upside down.

Removing LGA775 IHS is actually very easy if done right.

Just remember:
DO NOT TRY TO PRY IT OFF

CrazyXP1700

09-13-2006, 04:01 PM

Hence the 4 razorblades suspending the cpu... so it just falls off...

prying screwdrivers is too risky IMO... after killing 2 cpus that way...
i mean if your using percision screwdrivers... their still twice as thick as a razorblade, it will flex the package too much, possible seporate the DIE fom the PCB, and will almost definetly warp the package every time...

screwdrivers are not necessary... and too risky...

menlatin

09-14-2006, 08:23 AM

it was pretty funny when i literally poppe dmine off as well. We were slowly tourhcing the top with the cpu suspended on the blades, and then all of a sudden a "POP" and it was done. It seems to me, because of the pop, that dudring installatin of the IHS, they must put ALOT of pressure in the center trying to get good contact, and the the flex of the IHS is still present when removing.

largon

09-14-2006, 09:17 AM

Update expected within 24 hours.It's still warped.
Think I'll tighten the screws...

Funny thing is that there's no visible damage but the damn thing just doesn't post... Shutdown after 3 secs.
The cpu does power up for it gets quite warm during bootup.

Stigma

09-19-2006, 04:42 AM

shamino pried upwards, wich lifted the core off, if he had twisted, he would have had no prob

This is true, but why risk it at all? Let gravity do the work! When the soldr is actually running, the amolunt of force needed to make it pop off is miniscule. If you use crazy's method, the force of gravity allong with the slight tension of the razor blades will pop it off, AND are garantueed to not get overzealous and apply too much force, as Sham did wrong =)

I removed the IHS on a 2.8C northy with a soldered IHS. I put the edge of a single thin razorblade under the IHS, held the blade with pliers so the IHS was face up, and heated the IHS with a heat gun for about 15 seconds. It popped off and fell a few inches onto my carpet.

It posts fine and there is 5c idle temp drop as measured by BIOS. I haven't tested further because I still need to remove the remaining TIM.

peeps, you NEED to use a torch. You can buy them at most hardware stores. you can use the ones that take the disposable tanks. Sometihng like this

Honestly, I'm too nervous to use a torch. I'm afraid that I might heat the CPU too much. I don't see why such extreme heat is necessary considering that the TIM melts at less than 100c.

A heat gun set to 550c worked fine on my 478 northwood (2.8C SL6WT). I finished cleaning it and it works fine at default settings (didn't test any OC yet).

celemine1Gig

yeaaaahhahahahaa

i use lighter and heating the ihs about 20 to 30 sec
and it just pop out!!

then i clean the top, put into mobo!!! .... hahaah no boot!
i feel so good now!!!!!!!!

core is perfect look tho hahahaha

I also thought that I killed my CPU after removing the IHS. BUT, it is alright. You have to watch very carefully if the CPU and the heatsink do have proper contact. If either the CPU contacts don't get forced down on the socket pins with enough pressure, or the CPU-Die and heatsink don't have enough contact, then the CPU just won't boot. It's sometimes kinda tricky to find out. Sometimes it seems as if there would be enough pressure, but in reality it just isn't enough enough and you get no boot. I found out that my CPU was OK, after I had remounted the IHS and tested again.
Although you could indeed have destoyed the CPUs by heating them too much for too long. :( A normal lighter isn't really appropriate as it takes much too long to heat the surface.

550c are too hot. Just remember THG videos, when they burned A-xp's without cooler. They died after 300c temp.

The flame temperature of ~550°C is absolutely no problem, as you don't heat up the Die material directly, but the IHS instead. You just need to really carefully watch the time you spend heating it and of coure the IHS temp. You have to remember that although the flame may have a temp of 550°C, the IHS and Die temps won't instantly shoot up to that level, too. They will rise kinda slowly to the level that you desire. I used a little torch and that thing reaches flame temps of over 1000°C. ;) Guess what, it worked well. Just don't point the flame anywhere else than directly on the IHS's metal surface. :D

I agree with the info in that link. With polished surfaces it seems very easy to get the sandwich effect, or floating between the HS and IHS. A think layer of TIM on the HS without a polished lap works best, IMHO.

its damn easy to remove the IHS of an Intel CPU but you have to make sure the base of the cpu cooler will make contact with the die. as the die is lower than the LGA mounting lid.

Heat it up and the IHS will simply POP off, no prying required, the chip will fall off, just cut the black seal around the IHS and wedge some blades inbetween the PCB and IHS.

I wouldn't go the frying pan route. Too many variables, you could wait too long and cook it.

Use razor blades, a torch, and gravity. As long as you're on planet earth, the IHS will pop at the right time every time. Team NexGen has pictures of the blade method and several more interesting methods at: http://www.nexgenconsulting.net/projects/8ghzproject/intelihsremoval/

p.s. We tried a heat gun, it worked, but took too long; torches are more fun anyway.

AliG

05-26-2007, 05:53 AM

Yeah, we at daclan found that out the hard way, but at least we had tried it with an old celeron first

I know about the other methods, but the problem is that if you heat up the core too slowly, the the core will come of instead of the ihs

05-31-2007, 12:16 PM

I don't think it's the size of the die that makes a difference, the problem you run into is that there are some resistors and what not on the top of the die that you may possibly hit when cutting the ihs off with a knife, that's why many go the razor way and do a couple of rounds around the cpu instead

c2d probably has the smallest core, though amd's 65nm chips have less transitors last time I checked; I don't have exact measurements, but a way to find out would be to check out some of the ihs removal threads beyond this one or even this one for some pics for a general image

I always enjoy reviving dead threads, so I was after some advice. I got the IHS off easily with razor blades and a butane torch. But my core is covered in solder and i'm not sure of the best way to get it off now that it's hardened... seems like a stupid question, but i don't want to heat the core directly.

it's flat, but not smoothe a lot of biggish ridges in the solder...

Any great ideas to remove the solder? next time I will try to use a razor on the core when it's hot, but i don't have a clamp so a little tricky.

thanks!

You can get the solder of by picking it off with your pinkie nail or just use 2000 grit sandpaper to sand off the solder. also lapp it gently and don't lap to far.

Did it today on an dead X6800 i have. Used Crazys manner to it and only had a heat gun.

OMG it does go pop, it really springs off.

Defo need a way to surport the CPU for then IHS pop off. Anyway it took 5 maybe 8 seconds with the heat gun and off it came, core intacted and perfect.

Idealy i'd like to clean it all just for a keep sake, what the best way to remove the left over solder on the core and the RTV silicon that sealed the IHS off.

Oh and i also was able too see how and why it died!

I also too some time to look at the IHS, really really thick. Lapping will only make it so thin but has anyone though about machining it down a little?

I used a credit card to scrape off the solder that remains on the core. Just scrape it off, took me about 5 minutes to get the most of it off. The sealant itself might come undone with a strong solvent. You could machine down the IHS but I personally would rather pop the lid and seal it up with tape if I'm going to do that much work.
