Super Talent announced a double up on their DDR4 LRDIMM modules with the new 64GB capacity modules (F21LQ64GS), double the capacity of the previous 32GB modules. Super Talent’s quad rank 64GB DDR4 load reduced DIMM modules are targeted at server environments which allow more DIMMs per channel to be used in order to take advantage of an increased memory capacity. A buffer chip replaces the register on these modules, in order to help minimize the loading on a system and increase the speeds.
You’ll need a Haswell-EP platform to take advantage of these modules that run at a speed of 2133MHz and come with CL15 ratings. As these are PC4-17000 DDR4 modules, they’ll only consume 1.2V and are of course ECC modules. There’s no need for fancy heat spreaders with a lot of colours and hip design on such modules, and you won’t find that either. They’re plain as they should be.
LRDIMM can be a big advantage as the amount of DIMMs per channel increase. LRDIMMs offer lower latencies and are able to run at higher speeds. At three DIMMs per channel, the bandwidth speed gap is increased while latency tax from increasing the DPC has been reduced. All modules are quality tested in-house and are built to JEDEC standard specifications. The DRAM vendor can variate, but it can be determined by the last Character X of the Part number.
