Can you buy waterblocks for graphics card memory?

It's been running without heatsinks since I got it, but it's now starting to get artifacts even when it idles. I tried fitting zalman ramsinks but there seemed to be some kind of EMI between the ramsinks and the soundcard which stopped the computer booting.

Does anyone have any suggestions for how to sort this problem out?

The card (leadtek 6800gt) did come with a heatsink for both core and memory. I took it off to water cool the core though. It's lasted about 6 months without any heatsinks on the RAM, until now :(

I've ordered an alphacool vga block, so i'm going to see how I get on with that. Might be able to get a decent memory overclock with it :)
 
lol, phase cooling the vga ram is a bit extreme :eek:

I've whacked a great big fan over the ram for the moment and it doesn't artifact anymore, so I guess it must be getting slightly hot. it has felt a bit humid in my house today. I started overclocking the core a couple of weeks ago, so maybe that is finally taking it's toll on the ram?
