Sandy Bridge-E and its quad channel memory is nearly upon us. Corsair is gearing up with a new 32 GB DDR3 memory kit. The Dominator GT memory kit is comprised of four 8 GB DDR3 DIMMs (Dual In-Line Memory Module) that the company claims are from strenuously tested and highly binned chips. Specifically, the DDR3 kit has a part number of CMT32GX3M4X1866C9.
The new modules feature Corsair’s removable red and black DHX heatsinks and a RAM fan. The quad channel kit is rated to run at 2400 Mhz with CAS latencies of 9-10-9-27, and all while running at a mere 1.5 volts. Further, the memory is also rated to run with CAS latencies of 9-9-9-24 at 1300 Mhz; however, having the higher latencies and corresponding higher speed of 2400 Mhz will result in better overall performance versus the lower latency settings.
The 32 GB quad channel memory kit is available now with an MSRP of $999.99 USD. How much RAM do you currently use in your systems?

Micron Technology and Samsung Electronics, in cooperation with Intel, Altera Corporation, Open Silicon, and Xilinx among others have formed the “Hybrid Memory Cube Consortium” to develop and encourage adoption of a new storage interface specification. This new storage technology is based on Hybrid Memory Cube (HMC) technology, which is comprised of PCB, a thin logic layer, and stacks of DRAM chips. These memory chips are stacked vertically on top of one another and connected via TSV.

According to Tech Connect Magazine, Micron’s Vice President for DRAM Marketing is quoted in stating “HMC brings a new level of capability to memory that provides exponential performance and efficiency gains.” Hybrid Memory Cube technology is claimed to be capable of using 70% less power than current DDR3 memory modules (DIMMs) while being up to 15 times faster.
Reinforcing Micron’s position is Intel’s CTO Justin Rattner who talked very highly of the technology and it’s massive bandwidth and I/O improvements versus traditional DDR style memory designs. The Hybrid Memory Cube is capable of sustained transfer rates of 1 terabit per second, and is “the most energy efficient DRAM ever built” by a bits transferred per amount of energy consumed.
Both Intel and Micron have expressed that the HMC technology will be a boon for data centers and high performance computing that demands low power and high bandwidth memory storage. Assuming the numbers pan out, the Hybrid Memory Cube will be quite a leap in memory efficiency and will further accelerate adoption rates of so called “cloud” applications as well as more efficient high performance servers used in scientific research endeavors. All in all, the idea of the Hybrid Memory Cube is cool stuff, and it will be interesting to see if the actual memory will live up to its grandeur name.
When building a computer, enthusiasts are likely to combine components from several different manufacturers, especially on the Intel side. Short of the power supply, hard drive, and accessories; however, AMD is slowing diversifying to provide components to put together an all-AMD system. Before today, AMD already had the motherboard, processor, and graphics card (including processor graphics if that's your thing), and today Maximum PC reports that AMD may be moving into the RAM market with its own line of Radeon branded memory. It seems that AMD's future Leo-like platform may resemble a small AMD branded borg cube.
The new memory in question is comprised of 2GB, DDR3 sticks and comes in three series branded the "Entertainment," "ULTRA PRO Gaming," and "Enterprise." The enthusiastic naming conventions aside, the Entertainment series looks to be the budget modules for those looking for stable DIMMs that get the job done for cheap. They have a rated speed of 1333Mbps and a CAS latency of 9-9-9. The next highest series is the "ULTRA PRO Gaming" series, which promises to be overclocking friendly. These DIMMs receive a slight boost in speed to 1600Mbps while taking a slight dip in CAS latency to 11-11-11. The final, and likely most expensive, modules are the Enterprise series. These modules are still somewhat of a mystery as the specifications have yet to be announced by AMD; however, they are likely geared more towards enterprise workstations than servers as they are unbuffered DIMMs.
Further, all three series are rated to run at 1.5V and have a height of 30mm. Unfortunately, there is no word yet on price or availability. There are; however, several photos of Radeon branded memory modules over at PC Watch for you to check out. Do you think AMD's move to enter the DRAM market is a good thing or a bad thing for future profitability?

Tagged: vengeance lp, memory, ddr3, corsair, 8gb
Today Corsair unveiled a new low voltage DDR3, low profile memory kit. Specifically, the new kit is named the Special Edition Arctic White Vengeance LP and is a 8GB, 1600MHz affair that consists of two “rigorously-screened 4GB DDR3 DRAM modules” that the manufacturer guarantees will operate at 1600MHz at CAS latencies of 9-9-9-24.
The LP in the products name implies the predisposition for use in small form factor and low profile systems where every inch counts, especially in systems where the power supply mounts directly above the motherboard. The new Vengeance kit’s heat spreader has a reduced height of 1.03” (or 26.25mm) and is ideal for these kinds of small form factor systems.
Corsair have further used the new special edition memory in an ultra quiet PC build on the company’s blog. According to Giovanni Sena, the Director of Memory Products at Corsair, “our latest offering, the Special Edition Arctic White Vengeance LP, gives builders, system integrators, and gaming enthusiasts the ability to assemble low-voltage systems with an appealing, stylish new look.”
The new Arctic White Vengeance LP memory kit is available now from retailers and will run you approximately $90 USD at time of writing.
