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.

The Basics

Introduction

If you have been visiting PC Perspective at all over the last week there is no doubt you have seen a lot of discussion about the currently running Battlefield 3 beta.  We posted an article looking at performance of several different GPUs in the game and then followed it up with a look at older cards like the GeForce 9800 GT.  We did a live stream of some PC Perspective staff playing BF3 with readers and fans, showed off and tested the locked Caspian Border map and even looked at multi-GPU scaling performance.  It was a lot of testing and a lot of time, but now that we have completed it, we are ready to summarize our findings in a piece that many have been clamoring for - a Battlefield 3 system build guide.

Tagged: corsair, vengeance lp 8gb, low power

Regular viewers of our podcast know that Josh's favourite component right now is RAM, specifically high performance RAM for dirt cheap.  This RAM would certainly count, not only do you get two 4GB sticks for $53, it is low profile and at 1.35V is very low powered as well.  Corsair Vengeance LP 8GB runs 1600MHz stock @ 9-9-9-24 timings and even features a white heatspreader to give you cool running and unique looking RAM.  It doesn't have to stay low power either, when Overclock3D started earning their name and pumped the voltage up to 1.65 they could reduce the timings to 7-8-7-24 or pump the speed to 1866MHz @10-11-10-27.

Does Patriot now offer the best deal on DDR3-1600 currently on the market?

Subject: Memory | August 29, 2011 - 03:29 PM |
Tagged: ddr3-1600, patriot, gamer 2, ballistix

According to Legion Hardware the Patriot Gamer 2 DDR3-1600 is the best value on RAM going.  They back that claim up with the Gamer 2 1600MHz @ 9-9-9-24 costing only $53 and keeping up with kits costing almost twice as much.  They also managed to tighten the timing without lowering the frequency, on an i7-920 they hit 8-8-8-20 and with an X6 1100T they managed 8-9-8-20 which is very impressive for a kit costing less than $60.  The full review covers two 8GB kits, the Viper Xtreme Division 2 “PXD38G1866ELK” and the Patriot Gamer 2 “PG238G1600ELKA".  Don't spend more on RAM than you have to.

"...when testing we found that the relaxed CL10 timing of the Ballistix Sport memory made it much slower than the Patriot Gamer 2 memory which uses CL8 timing. Therefore in short we believe that the Patriot Gamer 2 is the best value DDR3-1600 memory money can buy and in fact we would go as far as to say it’s the best value 8GB DDR3 memory kit available period."

Samsung Releases Engineering Samples of 32GB Green DDR3 For Future Servers

Subject: Memory | August 19, 2011 - 10:47 AM |
Tagged: Samsung, DIMM, ddr3, 30nm

Samsung recently released engineering samples of new 32GB DDR3 memory modules for evaluation. Specifically, the new modules are registered dual inline memory modules (RDIMMs) that use a “three dimensional through silicon via (TSV) package technology” that provide higher performance and density.

The new DIMMs are made from Samsung’s four gigabit 30 nanometer class NAND, and is capable of delivering 1,333 Mb/s. Further, they consume 4.5 watts of power per hour, which Samsung claims is among the lowest power consuming enterprise DIMMs. Compared to LRDIMMs (load reduced modules), the Samsung modules offer 30 percent energy savings.

971108110817_3d-tsv_32gb_rdimm_l.jpg

The company claims that these power savings are the direct result of the through silicon via technology that allows them to vertically stack the NAND and maintain power levels comparable to single stacked chips. Further, the company stated that they are working with CPU and controller engineers to hasten the adoption rate of higher capacity DIMMs.  No word yet on pricing or whether these DIMMs will ever see full production and enterprise usage in their current form.

AMD To Release 2GB DDR3 Radeon Branded DIMMs

Subject: Memory | August 8, 2011 - 12:38 PM |
Tagged: radeon, memory, ddr3, amd

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.

50094_Chip_frontand_Back228W.png

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.

Legit Reviews did a marathon testing run on Llano to see just how dependant is on the memory subsystem.  They took a variety of 4GB DDR3 DIMMs, at 1333MHz, 1600MHz and 1866MHz, which they tried in pairs as well as with all four memory slots filled.  Their testing shows that 1600MHz really is the sweet spot for Llano, not as expensive as the 1866MHz kits and in some tests noticeably faster than the 1333MHz DIMMs.  Also of note was the consistently better performance with 4 DIMMs as compared to a pair.

LR_stalker-memory.jpg

"We found that the memory bandwidth ranges from 13GB/s to 16GB/s with typical dual channel memory kits on our AMD A8-3850 APU and Gigabyte A75-UD4H motherboard. This difference doesn't sound that great, but a 3GB/s increase when dealing with 13GB is a very nice 23% performance increase. Most of this performance gain is seen when moving up from a 1333Mhz to a 1600MHz memory kit is where you'll see the largest performance jump. For example 2x4GB 1333MHz CL8 memory kit was able to hit ~12.7GB/s memory bandwidth, but the 2x4GB 1600MHz CL8 memory kit has ~15.0GB/s of memory bandwidth, which is a very nice 18% improvement over 1333MHz..."
