Although there are several DDR4 kits available for X99 motherboards, most modules are clocked at 2133 MHz and 2400 MHz.

G.Skill is looking to remedy that with the launch of its latest memory modules, which are clocked at 3333 MHz. Dubbed Ripjaws 4, G.Skill is looking to cater to the enthusiast segment with these modules, which will be available in quad-channel variants (4x4GB). In addition to the 3333 MHz modules, G.Skill is also launching slightly lesser clocked 3300 MHz and 3200 MHz kits in 16 GB (4x4GB) configurations.

The modules feature a CL timings of 16-16-16-36, which comes out to a latency of 9.6 nanoseconds. G.Skill was able to validate the latencies on a Rampage V Extreme. Base voltages for the modules are at 1.35V, which leaves a lot of overhead for overclocking. G.Skill is no stranger to overclocking, with the vendor stating last week that it was able to achieve a frequency of 4004 MHz using a liquid nitrogen cooled configuration.

Featuring a sleek black design scheme, G.Skill’s 3300 MHz and 3200 MHZ Ripjaws 4 modules will be available from September 5 on Newegg, with the 3333 MHz 16GB kit available now for $699. Other countries are slated to receive the modules later this year.

Kingston has launched new memory modules in the HyperX Savage line. The modules are targeted at the enthusiast segment and will be replacing HyperX’s mid-tier Genesis line.

Featuring a bright red heatspreader cast out of aluminium, the Savage line of memory modules are designed to offer high performance and reliability. With dimensions of 133.35 mm x 32.8 mm, the modules are fairly low profile and are ideal in builds that feature large CPU coolers like the Noctua NH-D15. We first saw this memory back in Taipei at Computex 2014 and were given the low-down on the company’s efforts to re-brand their three different tiers of memory into HyperX Fury for entry-level gamers (to replace Blu), HyperX Savage for mid-level gamers (to replace Genesis) and HyperX Predator which will remain the top end line of HyperX products.

The HyperX Savage memory modules will be available in 4 GB and 8 GB as single modules, and from 8 GB up to 32 GB as dual-channel and quad-channel kits. Frequencies range from 1600MHz, 1866MHz, 2133MHz and 2400MHz, while CAS latency is either CL9 or CL11, based on the model. The memory modules are compatible with a wide variety of Intel chipsets like the H67, H97, P67, Z68, Z77, Z87, Z97 and H61, as well as A75, A87, A88, A89, A78 and E35 chipsets from AMD.

As with all HyperX modules, the Savage line is backed by a lifetime warranty.

Back in 2003, AMD introduced the Opteron processor, world’s first 64-bit x86 processor capable of addressing more than 4GB of memory (32-bit) – no less than massive 1TB of memory, courtesy of its 40-bit allocation table. Processors of today are capable of addressing up to 8TB of SDRAM memory thanks to extended (46-bit) allocation table. However, until now, finding a high-capacity memory module with 32GB density was as rare as finding hen’s teeth and usually you would pay top dollar for it.

Upcoming 20nm manufacturing process enabled the creation of ultra-dense memory modules and with SK.Hynix launching its 20nm 8Gbit memory chip, there was no doubt something special was in the works.

SK.Hynix 128GB 64×8 PC4-2133P-L80-19 – World’s first 128GB DIMM memory

For SK.Hynix, the end result is world’s first 128GB memory module, designed for the new DDR4 memory standard. While there is no way that this memory would become a mainstream part (at 20nm node), it shows that the DRAM industry is ready to offer something special for the upcoming server processors from Intel and AMD. This memory module also makes the first time TSV (Through Silicon Via) technology was used, utilizing vertical DRAM silicon stacking, e.g. 3D chips (not transistors).

If a typical server CPU comes with eight DIMM slots, with this module you will be able to pair each processor with 1TB of DDR4-2133 memory, resulting in 68GB/s of available bandwidth. While this is ways away from a high-end desktop / workstation usage, the existence of 128GB module will drive the price of 8GB, 16GB and 32GB modules down, with 64GB modules expected to drop down in price by over a half.

There’s also a matter of the way how DDR4 works, reducing the voltage from 1.35V or even 1.5V (initial DDR3 modules) to 1.2V. The current (A) did go up, so do not expect great power savings coming from the memory side of things, but the sheer capacity should make up for it.

We expect this memory in working demo systems at the upcoming ISC’14 supercomputing conference (June 22-26), which takes place in Leipzig, Germany.
