I have a Q6600 running at stock speed with a stock cooler on a DDR2 Socket 775 board. I asked a co-worker about possible (cheap) upgrade options, and what he recommended was getting a halfway decent cooler, a DDR3 775 board and try overclocking my chip. Newegg has some DDR3/775 boards, but they are all limited to two DIMM slots and a max. of 8GB. I’d like to have 16GB as an option, so I may have to get something on eBay. Can anyone suggest some used DDR3/775 boards that would support 4 DIMM slots/16GB RAM?
