Seeing as my system RAM is already decked out with heatspreaders and my video card has RAMsinks already in place, I was forced to test these RAMsinks on the various chips on my motherboard. Just for the record, my board is an MSI KT3 Ultra 2, running a 1600xp overclocked to 1754 MHz. I used the copper sinks placed in the location you see above. I also slapped down two aluminum sinks on the power resistor chips.
