Bolt-on RAM/VRM sinks for 4850/4870?

any test using watercooling solution?, excelent job btw, love the color especialy

It will be a bit unless someone posts results... I have my loop torn down right now as I am working on a new build.

Out of interest was that using 8.8's, if so did you rename the exe? 8.8's have nerfed furmark, half the FPS, lower VRM temps and less current draw!

I actually used the 8.8's on purpose, because now it is a more representative test of what I would consider a "real world" load.

I repeatedly recommended not using Furmark before the fix because it stressed the card beyond what I would call reasonable for a stress test.

For example, On 8800GT/9800GTX's, Furmark would run about 5-10C hotter than during intense gaming use... that's about the increase I would consider normal for a gpu stress test.

On Furmark before the new driver though, it was more like a 20C+ increase between Furmark and gaming. It was to the point of ridiculous, and nowhere near anything you'd see in normal use, not even 3dmark or Crysis cranked to the max. Now it is back in to that 5-10C increase range I consider it to be a "proper" stress test for this card, and I now use it.


I'm going to be doing some gaming/3d06 benches with a day or two. Honestly though, I did not design these sinks for beyond normal gaming or bench/stress testing use. IMO ATI didn't design the card for anything beyond that either, hence why they put the lid on this abnormally abusive (for this card) stress test.
