Zeus I think more are using PSC or BBSE instead, though using Samsung/Hynix at 2600-3000 with a good IMC isn't going to hurt very much.

@bassplayer thanks for the info. I wonder if people just haven't worked on tightening them or if they do really need to be that loose. On Bulldozer I've gotten 2170 stable with Hypers, maybe 2200 on Ivy with CL5 LN2 and tightest possible tertiary/secondary timings would not be bad at all.

I know that manufacturers don't validate them anymore but hey.

I like to try a bunch of different combinations...
