Cooling VGA mem......

[Bleam!]

lo again :D

Whats the best way of cooling the mem chips on your VGA when you already have a vapo/prom on it?

(R9800Pro)

Hello!

FOr mem cooling, have to recomend TweakMonster BGA ramsinks.

Although i did reada review before about ramsinks on VGA cards and some did a tst with ram, ramsinks, watercooling and phasechange on ram, and in every type of cooling, the same speed was atainable.
I personally don't use them as my ram dosen't heat up that much as it is.

[gokickrocks]

strap the prommy to a copper plate that touches the gpu and the mem (at least on the bottom side)

Tt Sinks are ok but the tweakmonster have a larger surface area, they have a new copper version out (Tt that is)

or get 2 of those (http://www.zalman.co.kr/english/product/nb32j.htm) , cut them into pieces and glue them on your memory, best ram heatsinks i can think of

works fine for me :D if you want pics pm me your email, have no place to host the pics of my card.

On the last few cards I used the radioshack to220 alu hs, they are big and have alot of surface are, cost $1.59 and can be purchased locally.

check these out.
the best option I ever saw.
simple pure copper heatsinks.
double wide for NVidia cards like ti=4200's.
or cut these in half and have 16 for covering 2 videocards, like the mini ram chips that ATI cards have.

I love these things.
dirt cheap too.

how much do having ramsinks helps cooling? i wouldn't have thought much since BGA can easily tolerate high temperatures.

[saaya]

helped me a lot on my ti4200 before i was getting artifacts @ 550/560 now with heatsinks on max stable without artifacts is 580/590.

Craig the new copper version from tt includes copper heatspreaders for regular ram, not the vgaheatsinks, they are aluminum

If your at stock voltages, maybe 5 mhz on the ram OC, but if you do vmods to your memory voltages, ramsinks atleast buy you some peace of mind !

[saaya]

it gave me 30mhz+!

I know this is an old thread, but what you guys reccomend using to secure ramsinks to memory? I want the option to remove the ramsinks after a period of time.

Its a risky propostion removing them ! I use AS3 epoxy. Alot of folks use as3 epoxy in the 4 corners (small amount) and regular as3 in the center. When you get ready to remove the hs just stick the card in the freezer for an hour or more and they should come right off. I have also mixed the AS3 epoxy with regular AS3 and that seems to work good too, weakens the epoxy bond.

[saaya]

but you should try your mix first, that as3 epoxy is damn strong!

[Major]

I've had about a 50% sucess rate at removing hs epoxied on without damaging the video card.

On a video card just leave them on there !!! why would you want to remove them ? They will increase the odds that you can sell the card used and probably be able to get $$ more for it. I've even returned 2 cards with them on there for rma wihtout a problem ! lol

[Hell-Fire]

Stronger than monkey lovin' I'd wager.

That stuff can hold a midget from a sky scraper beam for atleast a day and a half.....wait, havent we already seen that somewhere before? :hehe:

I would be fairly certain that once I put them on there that I do not anticipate takine them off. I put some on my 4400 once, and I ruined the card ..... even after putting it in the freezer for 2hours. Basically it ended up pulling one or more of the memory chips a little to far from the pcb. :doh:

[iceman2g]

Can I put a few dabs of superglue at the corners and just put regular AS3 in the center?

[Major]

Alot of folks do that too, it should work fine. I've never tried using superglue I would think on BGA ram it would be hard to not to put too much superglue.

[saaya]

be carefull with bga memory, they are a lot easier to pull off the pcb than tsop chips.

[q149]

If you do use superglue keep one tiny section bare corner and use a super tiny speck of it.. I like thermal tape though.

[SAE]

I use arctic alumina epoxy to glue the sinks (aluminium, I made from an old slot athlon cooler) on the bga chips.

I already removed them four to five times because of rma/sell at ebay... from bga.

I take acetone with a little syringe (if it's the right expression for that, my girlfriend is a medical student), spread it in small drops sidewards to the ram/cooler that it can detach the cooler. If it's still not loosen I give it some more acetone and then I beat against the cooler with a heavy screwdriver or sth similar. Then mostly it pops off immediately :D

Clean the chips and all is fine :cool:

[Major]

Note to self: Never buy any used video cards from SAE ! hehe

Hey :p:

I never sold a non-working vid card... hum... :rolleyes: I'll better shut up now :D

At least they were working for someone "non-Xtreme" :D :toast:

[Stang_Man]

you can also use regular old epoxy and mix with as3.

that's what i did for putting a 1u heatsink on my radeon8500..

worked great, (but taking it off took off 1/2 the chip!! lol..)

[hedge]

I would just cut up old aluminium heatsinks and epoxy them on with the misture major slaughter was talking about. That way they can still be removed and you also will have better heat transfer.
