putting heat sinks on HALF of my vram on gpu

post #1 of 4
Thread Starter 
hi everyone

i have a sapphire 6870 1gb, and i've been wanting to put a new aftermarket heatsink and fan on it for a while, well now i have the chance but when i open it i see that my heatsink cant fit it. however, i didn't find this out until i had placed heatsinks on all the vram. when i try to put the stock cooler on it, i notice that i cant and see the reason is half of my vram heatsinks are keeping it from setting.

i want to know is it ok if half my vram has a heat sink and the other half doesn't?

please answer soon, im assembling my computer right now(for the 3rd time btw, not 1st time doing it)

You should try to post it here http://www.overclock.net/amd-ati/

It is not ok, all the VRAM should get a proper cooling or you will see graphical glitches and texture shimmering if they are overheated.

It depends on the cooler, it could be fine. As an example on the Accelero TwinTurbo you have fans blowing cold air directly on the PCB/RAM, so you can leave RAM chips without heatsinks as the airflow from the fans would cool them well enough. If you don't have fan(s) forcing air on top of the RAM chips (even thru the GPU HS) you should put RAM sinks on all chips.

Your words aren't bringing the clear picture of whats going on with you. Are you saying that a particular single VRAM IC is covered half with a heat sink and the other half is left open or are you saying that a series of VRAM's are completely left open and the rest of them are covered with heat sinks ??. If its the later i was talking about , then no don't do it. And if its like the 1st case , then it ain't a problem cause i myself have it in the same way on my GTX 470 !!
