I got this bundle. mobo, cpu and 1 stick of kingston hyperx fury ddr3. It is a 4gb stick HX318C10FR/4 is part number. I am looking to get an identical second stick so i can run dual channel. BUT when i look for the mem online, and search part number I find it and it is DIMM. my mem is 4gb DDR3 -1866 CL10 240 - pin UDIMM. I know you can not run dimm and udimm on the same board. For the life of me... I can not find any UDIMM.. I can find exact match but it is dimm. I cant figure this out. not even Kingston will answer my email on this! This memory was purchased in a bundle from tigardirect. Even they dont sell it... wt#.. lol
