With some snappy graphics and a short press release, Super Talent is introducing some new eight and sixteen gigabyte RDIMM modules for servers. RDIMMs, for those of you who many not immediately recall, are registered or “buffered” memory modules. Physically they look very similar to your run of the mill DDR3 sticks, but they place a lower electrical load on the CPU’s memory controller due to their registered nature. The benefit of this is that you can then load the CPUs down with a greater number of DIMMs then you could if you had used unregistered DIMMs. So using RDIMMs can expand your memory ceiling which is particularly useful in server applications.
Super Talent’s particular modules are both Dual Rank and Quad Rank. In the case of dual rank this means that you can fit two modules per memory channel into your motherboard, and in the case of quad rank this means you can have four memory modules per channel.
One of the caveats to multiplying the number of DIMMs per channel is that at some point you need to reduce the individual speed of each memory module to avoid over loading the CPUs memory controller. To that end Super Talents new offerings act as a perfect example of this larger footprint, lower speed, phenomena. The dual rank kit runs at a rather brisk 1333Mhz, while the quad rank kit on the other hand takes bit of hit and runs at a mere 1066Mhz. In any case both of these memory kits allow you to trick out your servers with rather large memory configurations, 512 GBs anyone?
Of course Super Talent is specifically aiming these new memory modules at servers that can support large memory footprints. Thus they’ve done extensive stability testing with server motherboards supporting AMD’s Interlagos, or Opteron 6200, line of products. As a side note, with the number of press releases from DRAM companys mentioning AMD’s Interlagos, you might be starting to get the impression that it’s some kind of memory eating monster. But that’s a story for another day, for now be happy that the Super Talented beings from San Jose have seen fit to offer us an even wider selection of memory options.S|A
