14 DAY TRIAL // Even though DDR4 random access memory isn't expected to become a marketable technology for a few years, some companies have been working on it so avidly that they are already shipping chips.
Not many though, which is why Innodisk deserves all the praise it can get now that it has started shipping samples of DDR4 (Double Data Rate 4) RDIMM (registered DIMM).
The data transfer rate of DDR4 is 3.2 GHz, but there is no doubt, even according to standards organization JEDEC, that it will eventually go beyond that.
After all, DDR3 was supposed to have 1.6 Gbps as a top limit, yet it surpassed it thoroughly.
It would also be odd for DDR4 to be limited to 2,133 MHz clock speed, when there are plenty of high-end, overclocked DDR3 modules that can go to 2,500 or more.
Indeed, while DDR4 is definitely well above the standard DDR3 performance of 1333 MH or 1666 MHz, it is bound to reach farther than 2,133 sooner or later.
Moving on, the power consumption will be improved as well. Which is to say, chips and kits will be much more efficient, by around 40% or so.
That leaves capacity, and there is definitely going to be a leap here. Maximum capacity per chip has been increased from 64 Gb to 128 Gb.
Thus, Innodisk can offer RDIMM in 4 GB, 8 GB and 16 GB for server customers.
“The result of almost eight years of development, DDR4 (Double Data Rate 4) technology improves on the previous generation, DDR3, in every way,” Innodisk writes in its press release.
“These new memory products provide users with greater performance, but can still cut costs by saving power and space, and reducing waste heat.”
Innodisk's DDR4 RDIMMs work on 1.35V, which contributes to the aforementioned power savings and the longer lifespan.
