SK hynix Inc has announced it has developed new 1Znm 16Gb (Gigabits) DDR4 memory. 1Znm will offer the industry’s largest density and total capacity per wafer available in existing DDR4 DRAM modules.

The company claims productivity of the new 1Znm memory modules has been improved by approximately 27% over the previous generation 1Ynm line. However, the manufacturing process does not require expensive extreme ultraviolet (EUV) lithology so 1Znm production will be cost-effective.

SK hynix 1Znm memory supports up to 3200Mbps data transfer rates, which is the fastest data processing speed from the DDR4 interface. The new 1Znm memory modules have increased power efficiency, therefore successfully reducing power consumption by around 40% compared to modules of the same density from previous 1YNnm 8Gb DRAM.

A new substance, not used in the previous generation has been applied to the manufacturing process, which maximises the capacitance of the 1Znm product. Capacitance is the amount of electrical charge a capacitor can store, which is a key element in DRAM operation. A new design to increase operational stability has also been introduced into the process.

“1Znm DDR4 DRAM boasts the industry’s highest density, speed, and power efficiency, making it the best product to meet the changing demands of customers seeking high-performance/high-density DRAM,” said Lee Jung-hoon, Head of 1Z TF of DRAM Development & Business. “SK hynix will start mass production and full-scale delivery next year to actively respond to market demand.”

SK hynix has plans in place to extend the 1Znm technology process to a range of applications including next-generation mobile LPDDR5 DRAM and HBM3 which will be the fastest DRAM in the future.

KitGuru says: SK hynix is always making technological strides and improving its products. It will be interesting to see this new memory implemented in HBM3 DRAM and how it affects future performance.

When it comes to high-end memory modules for enthusiasts, there is always a trade-off between their clock-rates and capacities. It is not easy to overclock DIMMs powered by multiple memory ICs [integrated circuits], which is why it is complicated to install a lot of fast memory. However, G.Skill on Thursday introduced its latest 128GB DDR4 memory kit that weds performance and capacity.

The new G.Skill Ripjaws 4 128GB DDR4 memory kit consists of eight 16GB 288-pin modules based on Samsung’s 8Gb DDR4 chips made using 20nm process technology. Each module can operate at up to 2800MHz with CL16 16-16-36 timings at 1.35V voltage. The memory sticks feature black Ripjaws 4 aluminium heat spreaders. G.Skill will offer different versions of enthusiast-class 128GB DDR4 kits with clock-speeds from 2133MHz to 2800MHz.

The high-performance 128GB DDR4 kits are designed for Intel X99 platform and Core i7 5800/5900-series “Haswell-E” microprocessors. When installed, they provide memory bandwidth of up to whopping 89.6GB/s. The modules fully support Intel’s XMP 2.0 technology and can set their clock-rates – which exceed standard JEDEC-approved DDR4 frequencies – automatically. The 128GB DDR4 kits have been validated on Asus ROG X99 Rampage V mainboard.

G.Skill’s new 16GB DDR4 memory modules provide server-class capacities as well as extreme desktop-class performance. Such modules will be a great choice for people seeking for maximum memory capacity (e.g., video editors, designers, etc.) who also want to play video games comfortably with maximum framerates.

“During development of these DDR4 16GB modules, we see amazing future potential for 128GB (16GBx8) memory kits in extreme high capacity operation on upcoming platforms,” said Tequila Huang, vice president of research and development at G.Skill. “We will be witnessing the beginning of a new set of standards for extreme capacity and performance DDR4 memory kits on both current and future computing platforms. Needless to say, we are very excited for this release.”

KitGuru Says: 128GB of DDR4 memory is a complete overkill for any high-end desktop today. At the same time, not a lot of server or workstation owners would like to use factory-overclocked modules not certified by makers of their systems. It would be interesting to see how popular will 128GB DDR4 memory kits get outside of the world of boutique PC makers, who manage to sell absolutely incredible configurations at unbelievable price-points…

SK Hynix plans to introduce new versions of its DDR4 dynamic random access memory chips capable of operating at higher clock-rates compared to those available today. The new chips will boost performance of high-end and performance-mainstream PCs in the second half of this year.

Nowadays SK Hynix, Samsung Electronics and Micron Technology offer DDR4 DRAM memory chips that can operate at effective clock-rates up to 2400MHz (2.40GHz). Manufacturers of high-performance DIMMs for enthusiasts have to use special printed circuit boards along with hand-picked memory chips to build memory modules capable of operating at 3.0GHz or 3.40GHz.

Starting from the second quarter of 2015, SK Hynix will sample DDR4 memory ICs [integrated circuits] officially capable of operating at 2666MHz, according to a document seen by KitGuru. The chips will feature CL17 17-17 latency settings at 2.66GHz clock-rate, 4Gb density, 512Mx8 or 256Mx16 organization, 78-ball or 96-ball packaging and will require 1.2V VDD voltage.

At present it is unclear when SK Hynix plans to start mass production of its 2666MHz DDR4 DRAM ICs, but it is likely that this will happen in the second half of this year.

The new high-speed DRAMs will be used for memory modules that will work at 2.66GHz, 3.0GHz, 3.40GHz and beyond.

SK Hynix did not comment on the news-story.

Discuss on our Facebook page, HERE.

KitGuru Says: It is a bid surprising that at present SK Hynix does not plan to release DDR4 ICs with clock-rate higher than 2666MHz. Perhaps, the company will add them into its 2015 roadmap at a later date, but so far overclocking prospects of DDR4 memory sub-systems do not look exactly good.

According to G.Skill, the new Ripjaws 4 DDR4 3400MHz 16GB (4GBx4) memory kit is made from hand-picked DRAM devices during  a “highly-selective binning process.” The modules have been tested for compatibility on the Asus Rampage V Extreme and Gigabyte X99-SOC Champion motherboards, the manufacturer said.

G.Skill did not reveal the price of the new modules and memory kits, but given their exclusive specifications, do not expect them to be affordable.

KitGuru Says: While premium modules that can operate at 3.40GHz will certainly attract attention of enthusiasts of extreme performance, the vast majority of end-users will hardly even notice the announcement of G.Skill. Still, a several quarters from now, when Intel Corp. introduces its unlocked Skylake-K processors for “mainstream” overclockers, 3400MHz DDR4 memory modules will certainly get rather popular.

Later this year Intel Corp. plans to introduce its new code-named “Skylake” microprocessors that will target mass market segments and will support DDR4 memory. As a result, the latter will gain market share. Nonetheless, DDR4 will remain more expensive than DDR3 in the coming quarters, according to Micron Technology.

At present DDR4 memory is utilized by servers powered by the latest Intel Xeon “Haswell-EP” microprocessors as well as high-end desktop PCs featuring Intel Core i7-5800/5900-series “Haswell-E” central processing units. While shipments of Xeon chips are on the rise, the overall share of DDR4 on the market remains low. The situation will change when Intel rolls-out its new “Skylake” chips that will support both DDR3 and DDR4 types of memory.

“DDR4 ASPs remain at a significant premium to DDR3 given the enhanced performance,” said Mark Adams, the president of Micron, during a conference call with investors and financial analysts. “As the market for DDR4 begins to take shape over the next 12 months and beyond the rate of growth should positively impact our average ASP.”

kingmax_ddr4_dram_memory_modules

Unfortunately, Micron has made no predictions regarding adoption of DDR4 by the market; it is unknown how many desktop and laptop PCs will use the new type of memory.

Thanks to increasing sales of servers based on the latest Intel Xeon chips, shipments of DDR4 by Micron in the Q4 2014 increased four times quarter-over-quarter.

Discuss on our Facebook page, HERE.

KitGuru Says: While it is clear that DDR4 will continue to be more expensive than DDR3, what remains to be seen is the significance of the price premium. If the new memory costs around 10 per cent more than DDR3, this will hardly slowdown its adoption by the market, but if the price difference is 25 per cent and higher, this will clearly lower popularity of DDR4 rather significantly.

Smart Modular Technologies, a leading independent maker of specialty memory and storage solutions, said Thursday that it has begun shipments of DDR4 memory modules in sample quantities. The DDR4 memory modules are designed for servers, micro-servers, workstations, storage and networking applications.

Currently, Smart Modular's lineup of available DDR4-2133 1.2V modules includes VLP (very low profile) and standard height RDIMMs up to 16GB, and ECC SO-DIMMs up to 8GB. The new DDR4 288-pin DIMMs feature all the advantages the DDR4 technology brings, such as improved power efficiency, higher performance, enhanced system reliability and other. Exact specifications of the DDR4 memory solutions from Smart Modular look as follows:

KitGuru Says: The fact that an independent memory module maker already obtained DDR4 chips from manufacturers and even developed special-purpose solutions based on them is clearly a good one. However, given that qualification takes time, the company will begin to ship its DDR4 modules in volumes  only in 2015. As a result, this year DDR4 DIMMs for servers and workstations will only be available from major DRAM and module makers.
