Removing the A64 IHS

[CD 1986]

I thought i'd try removing the IHS, just for fun to see if i could get a better overclock and hit 2.6Ghz with my 3000+ Winchester...it didn't work. Not only that, i have a dead chip now! Lucky i'm gonna upgrade to Venice anyway, but it means having to go for the 3200 instead of the 3500 / 3700, so that i actually have a working PC!!!

Plus it's a bank holiday here in the UK; so unless PC world happen to have a venice lying around tomorrow, it'll be middle / end of next week until i can get hold of a chip! But if it's a good OCer i'll forget my recent mishaps.

Will not be removing another IHS in a hurry!

What exactly had happend? Did you cut those little things or cracked your core?

i have removed ihs too. theres nothing good for me, just lost warranty
there is no t drop - no better clocking - all the same.
its a64 3200 winchester... removing was easy, like others said

sorry about my english

Hi, this is my first post at this forum

I want to show you my A64 NC 2800+ with Ihs removed, it`s looking quit nice Temperatures are lower than 5-6*C in stress.

sorry for my english

what heatsink do you have?

i was thinking about doing this but i'm afraid i'd crush my core...

Welcome. Nice keychain, but i think you posted in the wrong section. Actually, i'm quite sure.

What clocks do you get with that baby ?

[jiff]

Nice idea the keyring

[Ubermann]

I took my IHS off from Venice yesterday.
It was a hell compared to me old 3200 clawhammer.
And the core is sooo tiny and got scared just looking at it and thinking about my XP-120.

ubermann please take some pics

@daddy_fizz --> something such blue(?) silicone heatsink.

@M1nDH4cK --> Actually on AC 2650Mhz on 1,75Vcore....I`ve done vcore/vdimm/vdd mods on my Asus K8N mainboard, and I can set 2V Vcore Toomorow I will end my Freon Cooling and I wont to reach 2,8GHz

@jiff --> thx

I can only wish you the best of luck.
Oh, and if you want my advice : Do NOT pump it with 2 Volts.

OK, I will remember

I want to set 1,85-1,9V...I think that`s "safety" on FC On my first FC I have -5*C iddle / +9 stress on r600a....now i think that -20*c iddle / 0*C stress

Got myself such a keyring as well

Nice job on pulling the IHS off. I tried to do it on my 3700+ a lil while ago, but I got so nervous cutting into it (I thought I might cut the silicon by accident). So I just left it on

it isnt like it provides that much better of temps anyway

[ozzimark]

it dropped load temps ~8c on my clawhammer. that's decent imo

[totensiebush]

it dropped load temps ~8c on my clawhammer. that's decent imo

was it making decent contact with the core?
i suppose that if it really drops load temps by that much, i may have to remove it from my NC, although i might want to epoxy the thinnest piece of flat copper i can find on top to protect from chipping...

[ozzimark]

it wasn't too bad. the actual removal of the IHS was around 6c, then i lapped the core cause it was rounded a bit, another 2c or so off.

though, i highly advise against lapping cores. it's not safe unless you don't care anyway

[brandinb]

it isnt like it provides that much better of temps anyway

well i took the ihs off my 3700 diego core and droped 14 degrees celcius under load and gained prime stable from 2550 to 2725 and lost 14 degrees in between gaining 175 mhz more prime stable oc so yes for some it is worth it.

this is how i look at it if your using a copper base heatsink or watercooling and youre temps are high anyways it is probably because the contact is bad and you will get good improvements

if you using aluminum base heatsink and your temps is good then you have good contact and temps get worse going from copper spreader to aluminum on your heatsink

if you are using a copper waterblock for water cooling i can guarantee its worth it in any case as you will loose atleast 5-10 c and gain more oc and in my case loose 14c and gain huge oc increase of 175mhz so if on watercooling and getting 45c+ temps then do it but if your load temps are less then 40 then there is no gain to be had as my temps under load 1.725 volts went from 56c and fail prime in 5 minutes to 42c and pass prime all night long

It depends on your cooler. With my 7700CU, I could easily remove the IHS and just put a piece of metal as thick as or
thicker than the IHS under the retention clip on the inside of the heatsink where it pushes upon for tension to compensate.

If it always worked absolutely perfectly it'd just be the way candycan
Atleast yours is still ok

So you're running with a stripped venice + 7700Cu?
I'm seriously considering this because of my temps, much higher than my winnie (8-10C higher @ same speed and voltage), but seeing how people are afraid to break NC cores with water blocks, what do you think I am with this tiny tiny core?
