Samsung announced that it has begun the mass production of a new 30nm-class 32GB memory module for green IT systems. This is the first time in the industry that mass production using 32GB modules and 30nm class chips has started. The 30nm modules use 4Gb DDR3 DRAM chips.
“With this module, Samsung has secured the highest level of product and solution competitiveness in the DRAM market for PC, server and mobile applications,” said Wanhoon Hong, executive vice president, memory sales & marketing, Samsung Electronics.
“We also plan to ship more energy-efficient 4Gb DDR3 DRAM based on 20nm-class* process technology in the second half of this year, which will significantly expand the rapidly growing market for green IT memory solutions. Moreover, we intend to keep delivering the greenest memory products with optimal performance for customers,” he added.
The new modules that Samsung is producing include 32GB RDIMM and 8GB SO-DIMM modules.
The RDIMM modules operate on 1.35V and can perform at up to 1866Mbps, which is 40% better than the 1333Mbps 40nm class modules operating at 1.5V. The new modules also consume 18% less power. The 8 GB SO-DIMM modules operate at up to 2133Mbps at 1.5V.
Samsung expects that almost 10% of its total DRAM shipments in 2012 will be 4Gb modules.

Computer Memory, also known as RAM (Random Access Memory) is an integral part of your computer and plays an important role in the way your PC functions. In this guide, we will show you how you can test and identify bad memory modules on your PC.
If your PC is running on a single memory stick and emits endless beeps during boot-up, it is usually a sign of a completely damaged memory module. Identifying partially damaged RAM however can be difficult especially if your PC has multiple memory modules installed. But with a systematic approach and a series of memory tests, you can easily nail down the culprit memory module yourself!
Getting Started
Before proceeding further, let’s have a quick look at some of the most common symptoms of a bad memory module:
- Computer freezes, crashes, or shows the Blue Screen of Death (BSOD) for no apparent reason.
- Distorted graphics or interrupted media playback.
- BSOD during software/operating system installations.
- Computer crashes while you are playing games or running memory intensive applications such as Adobe® Photoshop®.

The most obvious factor on how to differ DDR3 from DDR2 memory is appearance. But, that is not as simple as it might seem. Unless you can find the specific reference on the memory stick, you will need to look at the key notch. Along the bottom of the memory stick, 240 pins insert into the motherboard. Among the pins is a notch. That notch prevents inserting the wrong type of memory into an incompatible slot. Looking from the top side, the notch on the DDR2 lies slightly to the right of the middle point of the memory stick. On the DDR3, the notch is slightly to the left of the middle.
How to Differ DDR3 from DDR2
DDR2 memory sticks do not fit into the slots for DDR3 sticks or vice versa. One reason why many manufacturers have been slow to adopt the newer DDR3 technology is because there is no backwards compatibility between the two. You cannot use a DDR3 when you do not have an appropriate slot in the motherboard for it. Some newer motherboards come with the ability for both types of memory to work. However, it is important to know how to differ DDR3 from DDR2 memory before you purchase it.
What else makes these memory sticks different? Transfer speed on DDR3 is double that of the DDR2. Transfer rates on DDR2 range from 400 to 800 Mbps. On the DDR3, the range is 800 to 1600 Mbps. The DDR2 has four internal banks of memory while the DDR3 has eight. The DDR2 does 4-bit prefetch and the DDR3 does 8-bit prefetch. The DDR2 uses more voltage than the DDR3 does. The DDR2 runs with 1.8V while DDR3 runs with 1.5V. DDR3 memory has a slightly higher latency than the DDR2. There are other technical differences between the two as well.
Currently, there is another significant way on how to differ DDR3 from DDR2 memory. The price is higher for the DDR3 memory sticks. Prices have continued to drop ever since the DDR3 came on the market a few years ago. However, the DDR2 sticks are still lower in price. But, newer motherboards are pushing the prices down on DDR3. The demand for the newer technology is starting to grow as higher memory requirements come into play with faster motherboards and chipsets. However, with the newer DDR4 technology planned for a 2012 release, the future of the DDR3 is still in question.

These memory modules will be available from major online retailers that includes Amazon.com, Bestbuy, Tiger Direct, Newegg, Micro Center, NCIX, VIP Computers (UK) and many others along with their chain stores throughout North America.
AMD DDR3 Memory ModuleAMD stated that, it is collaborating with memory module makers to create the AMD Memory branded products from components, which are qualified to meet certain specifications. They are testing and certifying these memory to make sure that the end-users can be assured of compatibility with AMD platforms.
While talking about the new Partnership with AMD, Paul Jones, CEO of Patriot Memory said, “Patriot Memory will bring over two decades of experience and expertise into this ecosystem, …Our proven ability to deliver the best technology at the most competitive prices will help pave the way to success for this memory line.”
Initially, these memory modules will be available in 2GB, 4GB & 8GB sizes based on the Price point & speeds. To be little more specific, the entertainment category module will feature 1333 MHz & 1600 MHz speed RAM which is designed for home theater PC application. However, the performance category module will support up to 1600 MHz of RAM speed with low latency. To enable the maximum performance Radeon edition will run at 1866 MHz speed.

The 4Gb DDR3 DIMM chips are placed in 32 Gb memory modules based on 30 nm-class chip architecture.

A year after Samsung introduced its 40 nanometer-class 4Gb DDR3 DIMM chips for servers, it has decreased the size the chip size to a 30 nm class chip lithography. The result is the release on Tuesday of Samsung’s 32 GB dual in-line memory modules (DIMMs) that use less power and are faster than previous memory modules.
Samsung, the largest producer of dynamic random access memory (DRAM), said the modules–which are packages containing DRAM chips for use in PCs, servers and other products–are targeted at the cloud computing and advanced server systems market, with an eye toward green power efficiency.
“These new chips represent an 18% improvement with same amount of density and are using less power,” said Jim Elliott, vice president of memory marketing and product planning at Samsung, in an interview. “While in the PC desktop this doesn’t make a lot of difference, when you’re talking about a data center using thousands of servers strung together, and you put it into the context of data centers using three percent of the electricity consumption in the country, these numbers start to add up.”
Samsung’s 30 nm class 4Gb DDR3 chip has an approximate 50% increase in productivity over Samsung’s 40 nm class 4Gb DDR3, released in February of 2010, the company said. The new chip reaches 1,866 Mbps and uses 1.35-volts.
Samsung’s other products based on its 30 nm-based 4Gb DDR3 chips include 16 Gb RDIMMs for servers and 8Gb SO-DIMMS for small form-factors systems. In 2012, Samsung expects to have more than 10% of its total DRAM chip production at the 4Gb (or higher) density, the company said.
In March, Samsung began producing similar30 nm class 4 Gb DRAM targeted at mobile devices in order to reduce power consumption and increase speed.
“Mass production of 4Gb LPDDR 2 is a tremendous advancement for the mobile industry, one that will enable our OEM customers to move quickly in launching better differentiated high-performance mobile devices into the market.,” Wanhoon Hong, executive VP for memory sales and marketing at Samsung, said in a statement.
DRAM modules are projected to reach 812.8 million units in 2011, up from 733.2 million last year, according to IHS iSuppli. While growth in 2011 for DRAM modules will be slightly down from the 14.6% expansion last year, it will be ahead of the market’s performance during the next four years, the firm said. Shipments of 4Gb DRAM are expected to account for approximately 10% of total DRAM shipments in 2012, 35% in 2013, and up to 57% in 2014.
Samsung is the market leader in DRAM, accounting for 39.3% of the DRAM market, down from 41.3% last year, according to IHS iSuppli. DRAM revenues for Samsung fell to $3.3 billion in the first quarter, down from US$3.6 billion in the fourth quarter last year. Moving forward, Samsung hopes to continually decrease power consumption and increase productivity through its “green memory” DRAM products by moving down the nanometer lithography, Elliott said.
“Ultimately we want to enable our end customers in the IT industry to have these very green data center build outs moving forward,” Elliott said. “The key is how do I expand the data center without expanding the data center. How do I increase capacity without increasing power consumption? I think these green memory solutions are doing this and I think that’s the trajectory we’re trying to drive.”
