DDR3 RAM is so ubiquitous, effective, and inexpensive that it’s sometimes easy to forget that there’s a new generation of memory coming. Actually, it’s coming quite soon; Micron announced that it has a polished DDR4 memory module that it’s been sampling, and volume production may begin before the end of the year for applications in 2013.

Micron’s module is based on 30nm technology and will result in RDIMMs, LRDIMMs, 3DS, SODIMMs and UDIMMs. For now, Micron has a 4Gb DDR4 x8 module (x16 and x32 components are coming), which should initially offer speeds of 2400 Mb/s. Eventually, the modules will hit 3200 Mb/s.

If you’re holding your breath for the first DDR4 kit for your next build, don’t. DDR4 will show up first in the enterprise space, and Micron thinks ultrathins and tablets will follow. Desktop kits are a long ways off.

In any case, the next generation of memory is on its way.

I have been wondering when they would move up from DDR3 the thing that baffles me on this is why not move up to DDR5 as it would have multiple benefits. First it has been used and made more efficient over several years now in video cards. DDR5 is also of course faster more heat efficient, energy efficient, and performance efficient than DDR4 is so why put out DDR4 over DDR5 as the next machine standard memory?????

Maybe its a cost thing? Money, die size, motherboard interface space? Dunno. However, i do know that my next rig will be a DDR4 rig, and yes i can wait for 1.5 yrs.

Depends on the costs,.........

Given the time between builds for me, ddr5 will be out by then. lol

regarding the ddr5 cost, i've just read a gtx680 with 4gb ram - it's 80$ more expensive. say custom cooler is 10-20$ (card is on reference clocks), so i guess that 1gb ddr5 = ~40$. of course, it may be completely wrong assumption

You seem to be confusing DDR SDRAM and GDDR. GDDR is RAM specifically designed for graphics cards; GDDR5 is actually based on DDR3 SDRAM. So, DDR5 SDRAM doesn't actually exist, yet.

There is no DDR5. GDDR5 is actually DDR3 tuned for use in video applications.

Faster memory is good but to some degree I feel this is a way for the memory industry to push their profits back up considering they are at all time lows with DDR3

I would agree with you, but when was DDR3 introduced? 3 years ago I think, so it was about time for memory to move to the next gen, yes?

low power consumption,

faster speeds,

definitely a go for DDR4.
