Samsung has recently announced a new set of DDR4 chips built on 20nm (nanometer) technology that should absolutely destroy existing storage capacities and allow for vastly more RAM per DIMM slot. Right now there is a significant premium that you pay for RAM cards. On NewEgg, 4 sticks of 8GB RAM will run you up a bill of $300 on average. Samsung is currently laying the stage for dramatic DIMM capacity scaling.
The 20nm deployments will start with 8 Gigabit integrated circuits and 32GB modules, but is ready to be scaled all the way up to 128GB. Samsung says that these are actually 20nm DIMM’s and not 20nm-class DIMM’s. If you are wondering if Samsung is currently able to produce these 128GB chips, worry no more because Samsung released an early statement saying, “We are ready to produce the 128GB DDR4 module’s whenever requested.” While this means Smasung is ready, it doesn’t mean that we will be seeing DDR4 everywhere. We probably won’t be seeing it in many places until early 2015.
Samsung boasts that DDR4 RAM is faster than all the other RAM cards out there (DDR3, DDR3 – L, etc…). However, DDR4 RAM isn’t a whole lot faster than DDR3, but the power saving implications are enormous. Here is Samsung’s official statement:
Samsung’s DDR4 modules boast a higher density and hold improved error correction features. These should assist greatly in improved reliability of the chips. To add on to this, these modules and chips use 1.2 volts which is the current minimum you can get away with. So far, with the cheaper prices for a more well rounded chip, you may want to consider this for your servers, computers, workstations, etc. What do you guys think, will you guys be upgrading your RAM cards?
