Don’t you wish every component in your computer were made by the same company? That’s AMD’s thinking behind a range of desktop DRAM — leaping into the game with VisionTek and Patriot Memory who will build the branded modules to Sunnyvale’s specifications, tweaked for speed with OverDrive tuning tools. We’ve already known about AMD’s venture into the DRAM game few months ago, but this time it is official.

The reason for AMD’s entry into the memory market comes from two areas. First, AMD’s APUs are now shipping in large volumes and can definitely benefit from higher bandwidth memory modules. Many people buy A-series APUs as part of a prebuilt system, and right now lots of OEMs are still cutting corners on the RAM and using DDR3-1333. That’s the second aspect of the move: AMD wants to enable a [buzzword alert!] “holistic customer platform experience”, and they may be able to help drive down costs for AMD platforms. A final element AMD mentions is a desire to drive and enable future memory product developments.

The other item to discuss is what AMD offers that we may not already have. Here the distinction between AMD branded memory and other options isn’t quite so clear, but AMD will be doing testing and validation in their labs using AMD platforms. AMD also notes that they will not be using any ETT (Effectively TesTed) or gray market RAM. The latter is used as a term to collectively group hardware that may be less desirable; as an example, Intel unboxed CPUs are “gray market” because they are intended for OEM use but can still end up being sold at retail.

Basically, gray market parts would cut out some of the supply channel (in the example just cited, gray box processors typically cut out AMD/Intel and only have a short warranty from the seller). ETT parts on the other hand are a way of cutting costs by skipping branding; the RAM is still tested and is supposed to be high quality, but without branding it’s one small way to reduce costs. Generally speaking, ETT memory is destined for value RAM modules, so basically AMD is saying is that their AMD RAM will start out a step above value RAM. AMD also states that they will take end-to-end ownership of the AMD Memory ecosystem, working with module manufacturers, memory partners, IC partners, distributors, and VARs (value added resellers).

As you would expect from any memory, the AMD RAM will work with both AMD and Intel platforms; the main difference between the tiers will be the speed and packaging. Entertainment Edition memory will target the mainstream/value segment, come in single 2GB and 4GB DIMM packages, and is rated for CL9 operation at DDR3-1333 and/or DDR3-1600; Entertainment Edition memory is already available, starting in October. The Performance Edition memory should start shipping this month, and it will come in 2GB, 4GB, and 8GB capacities (these are presumably two-DIMM kits with 4GB, 8GB, and 16GB total capacities; Bulldozer could potentially use four-DIMM kits). The main difference with Performance Edition memory is that it is rated for CL8 operation at DDR3-1333/1600 speeds. Last is the Radeon Edition memory, which will come in 4GB and 8GB kits and offer DDR3-1866 and up to DDR3-2133 support with CL9 operation (and presumably CL7/8 operation at lower speeds). The Radeon Edition parts will also have support for overclocking via AMD OverDrive software; availability is expected in Jan/Feb 2012.

The stuff will be available from retailers like Amazon, Fry’s and Best Buy Canada, but we don’t know how much it’ll cost to bring this level of branding harmony to the inside of your case.
