@ masky ,
FYI: as i have been suggesting to you that soon high speed rams with low latencies will be introduced soon. infact this will be the last great run for the DDR memories.
after that everything will be ddr2. meaning the focus or momemtum will shift to DDR2 by both intel and AMD (lowering the latencies and increasing the speed to 800 mhz). most of the quality or well known foundry's are already shifting to 11nm or 9 nm technology for the rams. which indicates DDR2 will be the mainstream memories soon for both the platforms and you might see amd upgrading the venice core to incorporate ddr2 memory support.
Whether the cpu socket / no of pins for ddr2 will be the same or different (than soc 939) i do not know but i guess a new socket will have to be introduced by AMD for DDR2 (a.k.a intel with their socket 775, about 300 more pins than previous 472 pins)
currently the well known foundry's majority production of quality drams is "used" by the mobile phone and mp3 player sector, where the profit margins are more than in the cut throat competition of pc drams. hence we see drams based on second tier foundry's (chinese) to be the main stream currently. good quality stuff goes in the more profitable sector. like mobile, digital players, laptops/ notebooks etc.... where profits are more.
good quality ddr rams for pc are actually "hand picked" or "binned" versions of this 3 year old technology. they are rated high speed after "rigorous" testing by co's like ocz , g.skill etc.....but it seems ddr 600 or thereabouts is like sort of "upper limit" for ddr technology. which as per the JEDEC specs should be able run @ 2.6V (or 2.8V for o/cers) hence you find there is a great premium charged for these high speed (LL) rams by the ram sellers.
the newer ddr rams i am anticipating will be from new wafers using the 9nm or 11 nm technology. the initial batches will be used for DDR. but once the cpu mfgr's themselves switch over to DDR2 (or greater) the "good" foundries will switch over to ddr2. only 2nd or 3 rd tier foundries, mostly based in china, will continue to produce cheap ddr for the masses.
so masky i hope this further adds to your "confusion"
hyeah:
meaning to decide whether to spend 300 us$ for "good" DDR "now" and replace the same with DDR2 platforms about late next year. (there will be tremendous pressure to change, given the benifts of DDR2 m/c's like for e.g. higher cpu speeds (4.5 ~ 5 ghz), 800 mhz minimum bandwidth etc...
)
i just love doing this............
