Cooling Memory Chips on 970 ?

[Randall8686]

Hi all,

Looking for a few little heatsinks to chuck onto the memory chips on the Back of my 970 G1, its got a full waterblock on the front but having a route around yesterday in the case whilst running furmark to check an overclock i felt the memory chips that had no heatsink on and i could not keep my finger on them they where so hot. What do people use ?

Any of the stick on memory heatsinks will do. They all perform more or less the same. Copper ones such as the Enzotech kits will probably cool a little better. I am surprised they get that hot though. The memory chips on my 780 barely get warm. OCUK currently sell this 8 pack of ramsinks. There is also a 12 pack. Make sure you clean the ram chips with IPA to remove and residue that is on them before sticking the heatsinks on.

Purchased yes they get very hot, Burn your finger hot.

Reckon the memory could be a reason for driver crash on a 250+ oc with a gtx 970? It has happened once after 4+ hours of gamig.

No Idea, However the core speed is not going to increase the memory chips much, But i am a little worried at just how hot they are getting. They get untouchable without an overclock in Furmark and with my overclock they get seriously hot. I have ordered the little heat sinks and will pop them on tomoz

It's really strange that they get that hot. Even stranger is that I just checked a review for your card and the backplate doesn't have thermal pads to cool the ram. They must have been baking under that. If the ramsinks don't help (they should) is there a backplate for your full cover block that provides cooling and is not just for looks?

The memory chips on modern graphics cards are made to withstand crazy temperatures, well over 100c. In fact many of the stock coolers don't even cover them at all, so it should be fine. I've run a 780 with only a universal waterblock covering the GPU chip itself for ages and I never had any problems with it.

Well i have the EK Full cover that Does cool the front memory chips with the water, (has a channel that does directly over the chips) But i cannot see from EK's website that the back cover actually cools the chips.
Your correct the standard back plate does not touch the chips all it does it restrict the airflow over them. So having the card "naked" with decent case flow will help however im really not happy with them being that hot !

Fitted and amazed how hot the little heatsinks get, Can just keep my finger on them but not for long
