You going to OC hardcore Rod? My Intel P55KG board is very nice to work with. I'm not OC'ing though so cannot comment on that. Looks like RAM ratios are limited as well. I have the option of 6x 8x and 10x however the board seems very solid and stable.
Just running some kingston generic 1333 sticks from MSY.
Only OC with air cooling, easier to do down here in Tassie afaik
EVGA, Asus, Intel & Gigabyte make P55 based boards. I've never used an Intel board for OC before. RMA this current Asus board me thinks.
