Removing the A64 IHS

[KILLorBE]

The next time someone does this if you can post a video that would be great!

That would be the most boring video ever

I was almost finished and the suddenly the knife hit the core and a piece got off the core. bad luck. maybe I wasnt being patient enough.

What kinda knife did you use?

I used a hobby knife which is pretty thick, but I took my time and didn't try to get it of at once, I had to go around the IHS twice.

Can someone please post some pics of Rev.E A64s with IHS removed?
E3 Venice, E4 SanDiego, E4 FX, E4 Manchester, E6 Venice, E6 Manchester, and E6 Toledo.
I want to compare the die size of them to know the difference between E3, E4 and E6.

Here is a pic of my Venice 3000 crappy original paste job...

Using Alphacool Nexxos waterblock and 3x120mm radiator, with IHS idle 39C - load 50C, without IHS idle 34C - load 40C.

With the IHS on, as soon as I started Prime95, temp would go up to 49-50C and drop down instantly to 39C as soon as I stopped it. With the IHS off the temp doesn't jump around like that anymore, ramps up and down more progressively.

Glad I went to the busy shopping mall just to get razorblades

Thank you Nano2k.
Is your Venice E3 or E6?
You can judge it from its product number.

Now, I need pics of E4 SanDiego, E4 FX, E4 Manchester, E6 Manchester, E6 Toledo, and E3 or E6 Venice

Just removed it on my 3700+ SanDiego 0522XPMW



Seems to finally get it to prime @ 2900Mhz , watercooled.

It's E3.

[Enz0]

Thank you Fosco.
But, can you post the pic from the top?
Because your pic is very difficult to compare the size.


Thank you Nano2k.

Maby later when i have to take the cpu out again. But i thing i`m not going to remember doing it

[Enz0]

I'll compare the pics in this post.

E3 Venice (ADAxxxxDAA4BP)
E6 Venice (ADAxxxxDAA4BW)
E4 SanDiego (ADAxxxxDAA5BN)
E4 FX (ADAFXxxDAA5BN)
E4 Venice (ADAxxxxDKA4CG)
E4 Manchester (ADAxxxxDAA5BV)
E6 SanDiego (ADAxxxxDKA5CF)
E6 Manchester (ADAxxxxDAA5CD)
E6 Toledo (ADVxxxxDAA6CD)



Die Size
E3 Venice = E6 Venice < E4 SanDiego = E4 FX < E4 Venice = E4 Manchester < E6 SanDiego = E6 Manchester = E6 Toledo

Now I want some pictures of E4 Venice (ADA3500DAA4BN) and E6 FX (ADAFX60DAA6CD).

[Enz0]

I've got a better picture of E4 SanDiego.

Comparing in this post.

Not sure how many have actually takin the IHS off then put it back on but my temps were good with it off but I had issues with the TXD block touching the resistors on the cpu so I put the IHS back up with some as5 between the core and ihs. TO say the least the temps are now the same as if I had the IHS off. So its not a matter of taking it off and leaving it as it is just getting better contact between the core and the ihs. I had lost some oc with ihs and now I am back to normal oc + 20mhz. Go figure.

hi..

before: 1.344volt full load 55C box cooler
after: 1.344volt full load 48C box cooler

Your picture is very nice.

Hey on that last pic the 4400+.. On the left side, are those chips or something thats above the surface that we need to worry about cutting?

I'm gona take the top off of my 4400+ and would like to know before i do.

How did you know it was making contact with the resistors on the cpu? Did it short or something?

winchester picture?

[Enz0]

winchester picture?

I want to know the difference between E3, E4, and E6.
So, I'm comparing the die size of them.
Winchester is D0, so there is no picture of it.

I really want some pics of E6 Venice and E6 Manchester now.

When I removed the TDX and looked at bottom of the block I could see where the resistors where touching the block. Made nice little marks. Really made we wonder if others are doing the same thing and not aware of it. Not sure if it would hurt anything as long as the resistors arent being crushed but I couldnt take that chance. In the end I lost nothing by putting IHS back on. Like I said before I gained my OC back with IHS on.

[eclypse]

Yeah i have the same probs right now.. That and also the block not making perfect flat contact with the die.. I put small stipes of black tape over them just encase they did touch so it would'nt short out if it could.

I dont see why even putting the IHS back would help that.. Those chips will still touch that as well.. THe only reason why it didnt touch before is the thick goop they used.

OK here are my finding thus far. Previously on air using an XP-120 my max stable overclock was 2650 at 1.6V. I then got watercooling and my max stable clock settings was 2700 at 1.56V. Very small improvement after dishing out $500 bones. Now that I finally removed my IHS which took me two tries on two separate days I have noticed my temps only dropped 2-3C LOAD and IDLE 1-2C. Not much of an improvement; however, I did noticed that dual priming (with affinty set to each core) no longer results in an instant temperature increase. Before the IHS was removed my temps went to 38C instantly. I mean the moment I thought about hitting that "OK" button my temps were at 38C. With the IHS removed I actually saw a gradual increase from 27C->31C->35C and from 35C it fluctuates a lot with the max being 37C. Ambient room temperature is 23C. I am currently dual priming and dual super pi at 2800Mhz at 1.55v. Before the IHS this was instant fail, so far so good at 45 minutes. I have to say this was completely worth it. I'm almost certain that the IHS was getting a majority of the core, but not all of it. There must of been a "heat pocket" that was causing instability. I can't believe im actually priming at 2800Mhz at this voltage. This has been an instant failure everytime no matter what voltage I fed it. (upwards of 1.65v)

I highly reccommend this mod!

[shimmishim]

it was a nice mod.

it dropped my load temps from 50C's to 42C's.

only got 8C's load off my load and no gain in o/c yet.

temp drop is nice though, can't complain!

[Mr. Tinker]

I just wanted to check in on this thread with my experience.

I removed the ihs from my week 17 venice with ease, first try in about 7 minutes. I used an old-style shaving razor bought from Walgreens ($4 for 6 blades generic package). The razors bend very easily. I initially tried a hobby knife blade but it was too thick, even thicker was a box cutter blade.

After applying electrical tape to the blade all but 3mm from the edge, I gently inserted the blade intermittently along the sides, then once down each side I stuck the whole thing in. After each side was done I gently stuck the whole blade back under each side a pried just a bit at the corner using the leverage of the blade. After a few pries, it easily popped off.

The next step was to protect the core, so I put a shim from an old 9700pro around it, which fit perfectly after I sanded it down to the right depth.

The last step (since I'm using the stock heatsink while I prep my TEC setup) was to adjust the height of the heatink retention bracket on the mb. I simply unscrewed it from the motherboard and dremmeled off about 2mm from the bottom. Now the heatsink makes perfect contact.

Alot of people say you must use bolt-on coolers once you remove the ihs, but I found that shaving 2mm fromt he bottom of the plastic retention bracket works great.

[carmelo]

Just finished pulling my IHS off, I was a little intimated with some of the things people had said ... but as stated before just be very careful and DO NOT force the razor blade. Just work it around slowly. I found that starting on the corners and working my away from each corner was easier than starting at the opening people had stated they had done. Not saying my way is any better, but it happened to easier for me. This was done on an older NewCastle so we'll see what temps are soon.

The thermal paste seems to be applied well, but mine was fairly hard, almost like putty. Does every one else have the same consistency I do?

[Enz0]

I've got a picture of E6 Venice.

Comparing in this post.

This area is reserved for when I remove my IHS.

Will EDIT Tomorow.
