    Corsair Vengeance LPX DDR4-2666 Review

    Frustrated in my efforts to find a better-overclocking DDR4 kit than the one I’ve been using, I first found sets with slightly less capability, but twice the capacity. Then I discovered a kit with a similar rating, but a lower price. Finally, I looked at an alternative with similar overclocking headroom and more features. If my only purpose was to find faster RAM, I was not successful.
    Maybe a lower price would sweeten the juice. And perhaps it’s time I stop thinking like a reviewer and start pretending it’s my money. I mean, how many overclockers really want to pay more for their RAM than they paid for their high-end motherboard? For many of us, overclocking has always been about value!

    With Kingston’s almost-value-priced DDR4-3000 barely able to overclock past its rating, I began to wonder if a lower-rated part from an overclocking-focused brand might be a little more flexible. Corsair’s Vengeance LPX looks the part, particularly in its CMK16GX4M4A2666C15R (that last R is for Red) limited edition. It’s cheaper than Kingston’s parts, and if it can match them in an overclock, we just might find a top enthusiast value.

    Encouragement for this value-finding mission is spotted in the Vengeance LPX XMP registers, where we see that its DDR4-2666 rating comes at a mere 1.2V. Corsair even adds an XMP-2800 entry, just to act as a starting point for real overclocking. The rated timings aren’t great though.

    Kingston DDR4 hits 4351MHz



    Don’t try this at home

    Kingston’s new HyperX Predator DDR4 modules have set a new memory speed record thanks to Toppc.

    The overclocker pushed the memory to a whopping 4351MHz in single-channel mode, more than double the 2133MHz stock clock.

    TweakTown reports that it is still unclear what sort of cooling was used, but LN2 is a possibility. The rest of the system included an MSI X99S XPOWER board and a Core i7-5960X processor, working at just 1631MHz in single-core mode, sans HT.

    The CPU tweaks and the fact that a single memory module were used suggest the insane clock would be impossible to replicate in a real world scenario, but at least the potential is there.

    Corsair CMD16GX4M4B3200C16 Review

    Over the last couple of months, we published a number of articles where we saw Crucial, G.Skill and Kingston take their tries at the new DDR4 technology with various degrees of success. Naturally, it was only a matter of time before we could get our hands on products from the other big names.

    Happily, we did not have to wait for long for Corsair to lend us a sample so tonight we can start building an impression of what their DDR4 kits are like.
    Manufacturer Corsair
    Series Dominator Platinum
    Part Number CMD16GX4M4B3200C16
    Type DDR4
    Capacity 16 GB (4 x 4 GB)
    Frequency 1600 MHz (DDR4-3200)
    Timings 16-18-18-36
    Voltage 1.35 V
    Warranty Lifetime warranty
    (10 years in Germany and Austria)
    The model we are about to test is a 16GB quad channel kit that belongs to Corsair's flagship Dominator Platinum lineup. Its rated frequency is 1600MHz (a DDR4-3200 rating equivalent), which is achieved at 1.35 volts of input voltage and timings of 16-18-18-36.

    Even though this is one of the highest clocked memory kits that are out there, its stock timings are high even by DDR4 standards. Such a choice of specs might be explained by Corsair willing to leave themselves with more options if DDR4 component availability and/or overclockability was ever to get worse. If so, we find such a decision to be unreasonably safe as things usually only get better at the start of any technology's lifetime.
    When we first got the package from Corsair, we thought that it contained multiple items judging by its dimensions and weight. But as it turned out moments later, this version of Dominator Platinum comes in a box that is big enough for a cat to have a nap in.
    The packaging contains two plastic trays, each of which carries two modules and a fan assembly. It appears that Corsair were not too concerned about practicality when designing the latter as most, if not all, CPU aircoolers and even some all-in-one CPU watercooling solutions will render the additional memory coolers unusable due to clearance issues.
    Following with "Platinum" name tag, the memory and its cooler are finished in a colour scheme that is a combination of platinum-like silver and Corsair's trademark matte black.
    In contrast to many other memory kits that we get to test, the Dominator Platinum feature a number of unique constructive solutions.

    Firstly, the PCB of these modules is taller than usual thanks to exposed extensions above the chips that are designed to transfer the heat from the PCB directly to the heatsinks.

    Secondly, each of the modules is fitted with a pair of white LEDs that generate a subtle illumination in the memory area. If you want the light to be more than subtle, you can go on Corsair's website and buy additional parts that will make the modules shine brighter, literally.

    What comes down to the actual heatsinks, on the Platinum series they consist of four parts. Attached to each side of the module by the means of thermal glue, there is a pair of aluminium sheets that collect the heat from the chips and the PCB. The heat is then transferred via some metal-to-metal contact onto a finned heatsink that stretches across the top. Above it, there is a so-called light bar that is held with four screws on either side. The light bar does not take an active role in the job of cooling, its main purpose is just making the modules look cool.
    After fiddling with the screws and applying some heat to weaken the adhesive, we were able to take the modules apart to show off all the details of their construction. The centerpiece of the modules are, of course, the memory chips which in our kit turned out to be Hynix H5AN4G8NMFR which are usually referred to simply as Hynix MFR. As these chips have so-called 4Gbit density, each of the black memory chips has a 512MB capacity thus it only takes one rank (or one side) of either chips to build a 4GB module.

    The chips on our kit are different to Samsung K4A4G085WD that we have seen on 3200C16 press samples elsewhere, so it is likely that retail kits can be based on both Hynix and Samsung, especially taking into account the spec that is relatively easy for both types of chips to achieve. As of today, Hynix is generally a preferable option, which can be distinguished from Samsung by using Corsair's version number system: ver5.xx stands for Hynix, ver4.xx for Samsung.
    Each of the modules is flashed with an SPD, which provides some basic information on its manufacturer and model. The SPD also contains six JEDEC setting presets that are intended for backwards compatibility with DDR4-2133 supporting platforms. On top of those, there is an XMP profile designed to boil down the process of setting the memory to its specs to only changing one option in motherboard's BIOS.

    The memory settings obtained after loading the XMP profile on an ASUS Rampage V Extreme motherboard can be observed on a screenshot below:

    G.Skill F4-3000C15Q-16GRBB Review

    After G.Skill's major success on the enthusiast DDR3 market, many people expected more of the same when DDR4 came into the spotlight. However, things were far from smooth as G.Skill's first high-end DDR4 offerings simply did not have enough interesting features to justify the enormous price tag.

    Since then, G.Skill have made a number of adjustments to their product line. Not only did they release the 3200C15 and 3400C16 models that truly maximize the specs of existing DDR4 technology, but they also worked on bridging the gap between the low- and high- ends of the market.
    Manufacturer G.Skill
    Series Ripjaws 4
    Part Number F4-3000C15Q-16GRBB
    Type DDR4
    Capacity 16 GB (4 x 4 GB)
    Frequency 1500 MHz (DDR4-3000)
    Timings 15-16-16-35
    Voltage 1.35 V
    Warranty Lifetime warranty
    (10 years in Germany and Austria)
    One of these bridging models is the main subject of our today's article. On the surface, it looks similar to the red F4-3000C15Q-16GRR Ripjaws that we have tested earlier: it has the same capacity, has the same rated frequency, rated CAS latency and rated voltage. But what sets it apart are the primary timings, which have been relaxed from 15-15-15 to 15-16-16.

    At first, loosened tRCD and tRP might not seem like a whole lot of a deal. But in reality where these are the two timings that are hardest to tighten, this gives G.Skill a lot more options when it comes to choosing the memory chips to build the kits upon.
    Similar to the slightly faster F4-3000C15Q-16GRR model, the -16GRBB is shipped in a two-sided see-through plastic tray. This indicates that G.Skill do not consider this model as high-end so, aside from the usual case sticker, there are no additional accessories bundled with the set.
    Back in the days of DDR3, the Ripjaws series had an ascending red - blue - black color hierarchy. But as blue is not a very common colour scheme on DDR4 motherboards, it is natural to see blue version(s) of Ripjaws positioned same or below the red-coloured ones.

    Still, if your motherboard is solid black like some of Gigabyte and MSI's offering are, the modules do not look bad at all.
    Apart from subtle changes around the edges, heatsink construction on DDR4 versions of Ripjaws is exactly the same as on DDR3 predecessors. It is still a pair of stamped aluminium sheets that hold on to the modules by the means of thermal glue.

    The performance of such heatsink design was sufficient for the DDR3 models it was used on so it should have no problems with to cope DDR4 that is designed to emit heat in lesser volumes.
    Having weakened the adhesive with pre-heating, we were easily able to pull the heatsinks off the modules. Underneath, we found our kit to be based on Samsung K4A4G085WD memory chips of 4Gbit density in a single-sided (also called single-rank) configuration.

    Samsung DDR4 chips are uncharted territory for us as all DDR4 kits that we have previously tested, including a couple of 3000C15-rated models, were based either on Micron or Hynix.
    Each of the modules contains an SPD, which provides some basic information on its manufacturer and model. It also contains nine JEDEC setting presets that are intended for backwards compatibility with DDR4-2133 supporting platforms. On top of those, there is an XMP profile that is designed to simplify the process of setting the memory to its rated frequency, timings and voltage to only changing one option in the motherboard BIOS.

    In case with ASUS Rampage V Extreme, the precise settings applied after loading the XMP can be observed on the screenshot below.

    SK Hynix to mass produce 128GB DDR4 memory modules in Q4 2015

    SK Hynix has notified its partners regarding availability of its high-capacity DDR4 memory modules for servers. A good news is that the company will improve performance of such memory solutions, however, a not very good news is that the firm will delay mass production of its flagship 128GB LRDIMM by a couple of quarters.
    Last year SK Hynix introduced 16GB, 32GB, 64GB and 128GB DDR4 load-reduced memory modules for servers. The devices are based on 8Gb DDR4 DRAM devices made using 20nm process technology (vertically stacked into high-density DRAM chips using through-silicon-via technology) and have VDD voltage of 1.2V.

    Originally SK Hynix planned to rate its high-density memory modules to run at 2133MHz, but now the company also plans 2400MHz memory modules with up to 128GB capacity, which will help to increase memory bandwidth (by about 12 per cent) inside modern servers powered by DDR4, which will boost their performance and will improve performance-per-watt.
    SK Hynix plans to start mass production of 16GB, 32GB and 64 GB DDR4 memory modules for servers in the second quarter of 2015, just like it planned last year. However, 128GB DDR4 memory solutions rated to run at 2.13GHz or 2.40GHz will become available only in Q4 2015, according to a document seen by KitGuru.

    128GB DDR4 DIMM developed by SK Hynix. Images by Yonhap News, Myce.com
    By the fourth quarter of 2014 DDR4 memory will gain a significant share of the server market. In fact, it is projected that the DDR4 will become the mostly used memory standard sometimes in 2016. As a result, demand for 128GB modules will likely be rather strong as large enterprises adopt high-end multi-core server processors and high-capacity modules.
    SK Hynix did not comment on the news-story.

    SK Hynix to speed up its DDR4 memory chips this year

    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.

    ADATA XPG Z1 16GB 2400MHz DDR4 Memory Kit Review

    The 5820K has shown that a strong boost in CPU performance can be obtained for a reasonable price increase over the LGA 1150 Core i7 CPUs. And many of the X99 motherboards sit well below £200, making them affordable to enthusiast buyers. But where that entire value logic of Intel’s X99 platform starts to fall short is at the expense of DDR4 memory. One way of keeping costs to a minimum is by opting for a slower (therefore cheaper) memory kit. We test ADATA’s 2400MHz XPG Z1 16GB DDR4 kit to see how it stacks up against the higher-priced, faster alternatives.

    ADATA‘s brightly-coloured XPG Z1 memory modules are optimised for an Extreme Memory Profile (XMP) configuration of 2400MHz with a DRAM voltage of 1.2V. Primary timings are set at 16-16-16, which is looser than average for DDR4. Many of the faster – 2666MHz and 3000MHz – kits that we have encountered run with the technology’s JEDEC timings of 15-15-15.
    Different capacities of the XPG Z1 kit are available, although the set that we are testing uses four 4GB DIMMs to give a 16GB capacity with a quad-channel link.
    Asus’ trustworthy memory QVL for the X99-Deluxe motherboard suggests that Hynix MFR-based memory chips are found under the hood of ADATA’s modules.

    Two strips of metals converge atop the DRAM PCB to form ADATA’s stylish heatsink. By using two separate strips of metal, rather than a single block, the heatsinks are easy to remove. That’s good for overclockers who fancy their chances on the silicon lottery.
    A gradient increasing towards the centre gives each memory module a maximum height of 44mm. While this is around 13mm taller than the bare PCB height, it is still short enough to minimise CPU cooler interference.

    A carbon fiber effect is given to the XPG logo and provides a welcomed section of contrast against the bright red surroundings. ADATA doesn’t let the kit’s aesthetics slip elsewhere, either; the PCB is pure black – there’s no ugly green in sight.

    Specifications:

    • Model Number: AX4U2400W4G16-QRZ.
    • Compatible with Intel X99 chipset and Haswell-E processors.
    • Frequency: 2400MHz (PC4-19200).
    • Timings: 16-16-16.
    • Voltage: 1.20V.
    • Quad Channel Kit: (4x 4GB).
    • XMP 2.0 Ready.
    • Lifetime Warranty.

    Crucial's DDR4-2666 prefers 2400

    Make sure to visit your UEFI after installing Crucial's Ballistix Elite DIMMs' as this 16GB kit defaults to the JEDEC profile of DDR4-2400 @ 16-16-16-39. One quick click later to XMP and you will hit the advertised DDR4-2666 16-17-17-36. This kit ships with the Crucial Ballistix M.O.D. utility to give you temperature readings in real time, see exactly what frequencies and timings you are running at in Windows and for those kits which sport LEDs, the ability to program a lightshow. Hardware Canucks spend some time overclocking this kit and found the best performance to be with DDR4-2750 @ 12-12-12-26-1T. It is a good kit of DDR4 but remember it will cost you, in this case about $335.

    "Enthusiasts have been waiting for Crucial's Ballistix Elite to hit the market and it is everything we could have wanted; overclocking headroom, performance and a lifetime warranty...it's all here."

    The new Corsair Dominator Platinum Orange Edition RAM is so satisfying

    The polished metal finish and unique color design ensures that this new addition to the Corsair Dominator series is like no other. The Dominator series as a whole certainly isn't new, I remember filling my i7 2600k system back in 2011 with a few sticks of red Dominator's - however the product name lives on and it sure has aged well!


    Custom-designed for and paired brilliantly with the GIGABYTE GA-X99-SOC Force motherboard, we can't wait for this DDR4 RAM to be thrown into a system - paging all modders!

    Featuring a speed of 2400MHz and a tested Latency of 16-18-18-40, this set of RAM is "guaranteed to run at 3400MHz at ambient room temperature" according to Corsair's official website.

    SMART Modular Expands Its Lineup of DDR4 NVDIMMs With 8GB and 16GB Densities

    SMART Modular Technologies, Inc., a leading designer, manufacturer and supplier of specialty memory and storage solutions, including memory modules, flash memory cards and other memory and solid state storage products, today announced the expansion of its NVDIMM product line with its new 8GB and 16GB DDR4 NVDIMMs available in a single rank, four bit configuration. SMART's full lineup of DDR4 NVDIMMs now include two configurations; a single rank eight bit configuration in 4GB and 8GB densities, and the new 8GB and 16GB options. The new NVDIMMs are targeted for server and storage applications to improve performance.

    NVDIMMs transform main DRAM memory into persistent memory resulting in higher performing servers by allowing big data, transaction logs, and other latency and performance-sensitive data to be accessed at DRAM speeds without the risk of data loss. Rather than reading and writing big data or transaction logs to traditional storage media such as SATA SSDs, PCIe NVMe SSDs, or HDDs, they can be written to and read from main memory without the risk of data being lost due to any sudden power loss (SPL) event. Server performance in terms of lower latency, higher IOPS, and greater endurance all increase dramatically with the use of SMART's NVDIMMs.

    SMART now supports a complete lineup of DDR4-2133 NVDIMMs ranging from 4GB to 16GB configured as 1-rank x8 and 1-rank x4. SMART's DDR4 NVDIMMs are targeted to support a wide range of industry standard and OEM server and storage platforms from Intel, Supermicro, Lenovo, HP and others. NVDIMM industry adoption is being driven by JEDEC standardization and the growth of In-Memory Computing (IMC) where entire databases need to be loaded in main memory for real-time analytics. SMART is further entrenched in supporting DDR4 NVDIMM standardization with its work in coordination with JEDEC.

    Working closely with its customers over many years, SMART has developed and incorporated into its DDR4 NVDIMMs, SafeStor technology, a feature-rich, mature command and control register interface. SMART's DDR4 NVDIMMs also have an integrated DRAM and flash controller with end-to-end data integrity protection including internal CRC-32 and parity protection for FPGA SRAM. Backup power can be provided by the host system through a JEDEC-standard 12V power rail or by a tethered Backup Power Module (BMP). SMART provides several intelligent tethered BMP options including a 2.5" SSD form factor supercap module and several other hybrid solutions that are currently developed or in development.

    Applications where response time is critical will greatly benefit with the added persistence that SMART's NVDIMMs provide.

    SMART Modular Technologies will be showcasing its NVDIMM offerings within its DRAM product line at Embedded World 2015 Exhibition and Conference, Nuremberg Messe, Nuremberg, Germany.
