First off I have a question about my memory clock. I thought it was 175/166, but when i used NV Max to overclock the video card it tells me its 334 Mhz. Im almost certain that this card does not have DDR memory so why is it doubleing the memory clock. Second question has anyone tried to put a Blue Orb on this card. Take a look at my signature the info is there. Also what size ram sinks should i use?
