Keeping Fully Buffered DDR2 cooled down?

post #1 of 5
Thread Starter 
Might be a topic for the mods forum but I have a Supermicro X7DWA-N motherboard (dual LGA771, 8xDDR2 FB-DIMM slots) and I'm already using a pair of ultra low voltage Xeons (L5420), which stay nice and cool, but my 8x2GB sticks of Hynix DDR2 get *hot*. I haven't measured them with anything but any more than 1-2 seconds of skin contact to the heat spreaders on the RAM sticks results in extreme pain.

Question is, what can I do to keep these things cooled down?

Is there not any airflow going over the sticks?

What benefits does DDR2 FB grant to a system, just curious I know a friend who has some.

That or try to position a fan inside the case to blow air on the dimms.

Find out what Samsung and Micron do for their OEM modules. Some have a heatsink over just the buffer or ECC chip, and forced air cooling is rarely necessary because of the high 85C temperature rating.

No offense, but extreme pain or just extreme sensitivity? Because some people think a mild 50C is scorching hot, while others don't mind 80-90C that burns the chip's writing into their finger (I minded the latter very much -- 10 MHz Intel 286).
