After running RTHDRIBL, the bare RAM only gets to 52 - 55 degrees Celsius according my Compunurse probe. That doesn't seem too hot. I actually have 8 copper RAM sinks lying around, but I don't think I'm going to bother to put them on. My RAM doesn't reach the speeds others have reported, but I don't see RAM sinks performing any miracles.

It all depends on the overclock as well. The GT has 2.0ns ram, so it wouldn't matter , but I'd imagine for DDR2 as well as anything below 1.6ns ram, a decent overclock would need cooling. For example, I have my 6800 Ultra at 1300 MHz for the GPU, and I can feel the stock heatsink HOT to the touch. Imagine if there were no sinks on them? You'd find most people using ramsinks on their videocards if they plan on overclocking high, unless they phase change. A friend of mine bought both the 6800 and the MCW50, and he was able to achieve higher overclocks with an MCW50 and Frozencpu ramsinks over the 6800 block... it might just be his system though...
