Best GeForce Ti4200 RAM Heatsinks

[Furton]

As the title says, what are and where can I get the best RAM sinks for a GeForceTi4200?

I've seem some Thermaltake ones but would like other suggestions. Also would copper or aluminum be better for a graphics card, I know copper sinks are better for a CPU, but does the same apply for gfx cards?

Hey

I got some Coolermaster Ally ones for my Ti4200 and they didnt improve my memory overclock by even 1mhz to be honest I think they are just and fad, and would reccomend other people to not bother with them!

Are the ones in that you have seen in the Thermal Take cooler gf4 cooler? as i got those ones, and they didnt improve the overclocking of my RAM at all. I believe that they are copper? dont know if i just bodged up the sticking of them or something...hehe

Copper is the best i believe, as it transfer heat better than other metals

[streetster]

you wont get much/any increase in overclocks on ram by adding heatspreaders to the ram, usually the overclock is limited by the ram, not the heat... anyhow copper transfer heat faster but retains it, whereas aluminium transfers heat slower than copper, but transfers the heat into the air quicker (not very good explanation but i think i'm right heh)...

anyhow, it really isnt worth the £10 or whatever you are going to spend on it

Ah right, cheers guys. Was hoping for a bit more out of my RAM but I'll leave it at 610Mhz if that's the max.

[Sumanji]

610mhz is immense mate My Ti4200 has 4ns Sammy and it craps out at 535mhz But I can get the core to 317mhz which is cool... also BIOS flashed it to run at 300/500!

Mines at 700 most of the time

Love golden samples

Agent - what overclocking application are you using. i can get my golden sample (ti4200) to 620 without artifacts, however with Riva tuner the next stage up is in the warning triangle zone, i dont want to try this. as last time i broke my friends mx440, by putting the slidly bar to the top, now it gives artifacts at stock speed - but he doesnt know yet

So should i just keep increasing it slowly, even through the triangle section?

Thats cheating

What speed RAM does it use?

Well mine is covered by RAMsinks, but i can just see the end it is .3 so i guess that is 3.3ns which i think is the same as my non-golden sample card....but this one just clocks a hell of a lot better (old one in sig)

silver mem sinks are best. unfortuantly i cba to make mine, so ive kept the alu ones.
theres not really any differnce between them - silver>copper>alu for heat transfer, i could explain why, but as usual, i cba, though i will if any one asks
memsinks will keep the mem colder. it will NOT help you overclock it.
i find memsinks make my 9700 mem clock worse, it will be the same for other cards aswell, as the mem chips are basicly the same (apart from different rating, size, number of them, and package).
two possible resons i can think of for this:
metal heatsinks ask like a tv ariel and the interfeerance affects the chips slighlty - grounding the memsinks might help.
second reson is that mem might just clock better when its hot, upto a certain point where it starts to corrupt.

mem chips afaik are basicly made up of billions of sillicon capacitors - more voltage the quicker they charge, the faster they will run stabily, obviuosly thats not accurate or detailed enuf explanation for any one to quote. volt mods should help your cards mem o/c a bit more. my mem is crappy infeinion, max i can get is 315mhz (630) so i havent botherd. mem vmod should get my card to 330-360 (660-720)

also another thing that helps with 9700's atleast, is more/cleaner power supply - having good 3.3 and 5v rails and also making sure the power regulation part of your card is adeqatly cooled should get a few more mhz.

I was just gonna cut this Intel P2 heat sink into lil ram sinks and stick it on with artic silver epoxy where do i find out what the codes on my mem means?

Interesting notion, but would EMI interference not best dealt with by sheilding rather than grounding?

I'm in agreement with you regarding ram sinks, don't bother with them unless voltmodding is being considered.

I do it via Nvidias drivers and the coolbits registry hack.
I run my Ti4800SE (4400 with 8x AGP) at 300/700 day in,day out

I'm not sure what memory is on it. For some strange reason, i think its 3.5, but that would be one hell of an overclock if it was. I cant see the chips because of the attached RAM sinks put on by Gainward, but I'm sure it has it on the box

i got a golden sample (ti4200, AGPX4,64mb) runing at stock

hmm explain...
i thought that grounding heatsinks would be the same as shielding..?
