Quad-channel DDR3-2800 ? ... I'd want to see a s2011 platform capable of that for 24/7 operation
If we're talking about benching, a lot depends on whether 1400/11-13-13 is faster than, say 1200/7-11-7 or not. If higher memfreq is the way to go, then we'll have to buy these gay Samsung kits and/or have to find ways for BBSE/PSC/Hypers to get there. If not, 1200-1300MHz will be your typical benching range, in which case I'd want to see 7-11-7 (PSC) being put up against 8-8-7 (Hypers)
