DDR2 won't even be obsolete by then. Millions of people are still using DDR.

Thats graphics memory.

DDR4 in its infant stages are as fast as DDR3 in its mature stages, this is always the case with memory.

DDR2 1066 was the de facto memory speed when DDR3 @ 1.333Ghz.

Even DDR1 with a triple channel memory controller would satisfy most users, I think...The difference will be tiny.

Just trying to follow the trends in RAM these days tongue.gif
I mean, most generic DDR3 = 1333 9-9-9
But a lot of mainstream performance DDR3 can do 2000 at those timings

Latencies usually always get better for both mainstream & performance in memory anyways (i.e. 667 CAS5 to 1333 CAS9 is a small improvement). Some DDR3 can do 1600 6-6-6, but finding DDR2 that can do 800 3-3-3 is even more rare. Likewise same with DDR2 vs DDR3 speed scaling, most DDR2 can do is around 1333Mhz but DDR3 has been tested at 3000Mhz+ before even.

If up to 3200Mhz is what a manufacturer says officially, it can probably also unofficially do more than that.

Any insight on why LPDDR2 isn't used? 1.8V vs. 1.2V seems like a huge difference, aside from the benefits of increased bandwidth.

HOLD ON A MINUTE
Did anybody bother looking at the memory module in the photo?
PC4-14900 (About 1866Mhz) - latencies 13-11
BOOOOOO mad.gif I have DDR3 that runs that speed with 7-7-7 latencies and most can at least manage that at 9-9-9

Unless those numbers don't represent the latency...

Why don't they make an IMC where each ram chip on the stick is on it's own controller/bus? wink.gif

Didn't Samsung invent the proc on all the latest smartphones as well? Both my TV's are made by them and they are all over the tech scene!
