Kaby Lake CPUs and the associated Z270 motherboards can handle DDR4 frequencies higher than we have seen previously, good news for overclocking enthusiasts. G.SKILL may be first past the post with new DIMMs, you can pick up their Trident Z DDR4-4266 DIMMs on NewEgg right now, $230 for a 16GB dual channel kit.
This extra speed does come with an associated cost, they rate the voltage of these modules higher than you would expect from DDR4 at 1.4V as opposed to the 1.35 we are accustomed to and you should keep this in mind when shopping for a motherboard. It will be interesting to see if these extremely high frequencies have any noticeable effect in gaming performance however they are already breaking records, 8 world records and 21 global first place records.
You can see the various frequencies and timings currently available, expect to see more companies announcing new DIMMs very soon.

[H]ard|OCP had a chance to try out Corsair's upcoming Vengeance LPX 3600MHz DDR4 on a Kaby Lake based system. The XMP settings for this DDR4 were 3600MHz with timings @ 18-19-19-39-2T and the system booted with no problems at these defaults, an improvement from some scenarios with Skylake based systems. Running Prime95 for over a day posed no problem for the system, however Memtest86 did until the RAM voltage was bumped up to 1.41v from the default 1.36v at which point it could pass the tests with no problems. This shows some promise for overclocking addicts planning on upgrading to the refreshed Intel chip.
"We were lucky enough to get our hands on a new set of Corsair Vengeance LPX 3600MHz RAM this week and we immediately put it work with the new Intel Kaby Lake Core i7-7700K processor that is to be launched next month."

Yesterday G.Skill announced the launch of the soon-to-be fastest DDR4 64 GB kit using 16 GB modules running at 3600 MHz. The new Trident Z kit uses Samsung 8Gb chips and pairs four 16 GB DIMMs supporting XMP 2.0 and CAS latencies of 17-19-19-39.
The DDR4 memory kit features stylized brushed aluminum heatspreaders with red accents similar to those used on existing Trident Z kits. Out of the box the kit runs at 1.35 voilts though overclockers should be able to push them further to eke out a bit more speed beyond the stock 3600 MHz!
Beyond that there is not much to the announcement other than G.Skill claiming the speed crown. Looking online, it seems the previous highest speed offered was 3466 MHz so the new modules are a decent bit faster.
According to G.Skill, the new Trident Z 64GB kit will be available in December. They have not yet released pricing, but I would expect it to MSRP for at least $570 considering G.Skill and Corsair currently have DDR4 3466 MHz 64GB kits priced at $540 and $530 respectively. If you are into overclocking, you can probably save a few bucks and overclock some lower specc'ed memory, but these might be good if you are building a workstation that doesn't need ECC (e.g. a video editing and streaming monster heh).

This particular Corsair Vengeance LPX kit comes with the Airflow kit, active cooling for your DIMMs which does require a fair amount of clearance around your CPU socket if you intend to install it. If you do not use the active cooling the low profile DIMMs stand a mere 31mm tall, which should fit alongside even the largest heatsinks. This 32GB DDR4-3200MHz kit has default timings of 15-15-15-36, Overclockers Club managed to squeeze out an overclock of 14-16-16-36 @ 3261MHz on this particular kit. Drop by to see the effect that had on performance in the full review.
"Right out of the box, this set of modules delivered excellent performance across each of the tests I ran. From synthetic to real world and finally in the gaming test, these modules delivered better performance overall than even the Dominator platinum modules I just looked at. The tighter primary timings and SPD tuning really brings out the performance potential of this Vengeance LPX 3200MHz 32GB set of modules."

You have probably recently heard of terahertz radiation used to scan physical objects, be it the T-Rays at airports or the the researchers at MIT who are reading books through the covers. There is more recent of news on researchers utilizing the spectrum between frequencies of 0.3THz and 3THz, this time pertaining to RAM cycles and the possibility of increasing the speed at which RAM can flip between a 0 and 1. In theory a terahertz electric field could flip bits 1000 times faster than the electromagnetic process currently used in flash memory. This could also be used in the new prototype RAM technology we have seen, such as MRAM, PRAM or STT-RAM. This is still a long way off but a rather interesting read, especially if you can follow the links from The Inquirer to the Nature submission.
"Using the prototypical antiferromagnet thulium orthoferrite (TmFeO3), we demonstrate that resonant terahertz pumping of electronic orbital transitions modifies the magnetic anisotropy for ordered Fe3+ spins and triggers large-amplitude coherent spin oscillations," the researchers helpfully explained."

Corsair's DOMINATOR PLATINUM Special Edition series comes in 32GB kits, either four 8GB DIMMs or a pair of 16GB DIMMs, in your choice of Chrome or Blackout finishes. All kits are DDR4-3200MHz but with the 10-layer PCB and DHX heatsinks Corsair feels that reaching 3600MHz will be trivial and higher frequencies possible for talented tweakers. They will be available directly from Corsair, $330 for the quad-channel kit and $300 for the dual channel.

Tagged: gskill, ddr4
Judging by a quick scan of Newegg USA, G.SKILL is pretty much alone in bringing 8GB DIMMs to speeds above DDR4-3733. They already have a 2x8GB kit in the DDR4-4000 and DDR4-4133 ranges, but they're now introducing a 4x8GB kit into the DDR4-3866 classification. The chip is rated at CL18-19-19-39 when supplied with 1.35V. This is much higher voltage than slower sticks, but, as far as I can tell, pretty good at that speed. It also supports XMP 2.0 to automatically configure your BIOS, which is a bonus.
Granted, I cannot think of too many situations where four channels of high-bandwidth memory will give you any real benefits, apart from obviously a narrow list of overclocking record categories. Current DDR4-capable processors can do up to 16GB DIMMs. Personally, I'd tend to err on the side of slower, denser sticks of RAM. I'm more concerned about leaving everything I want in memory, versus any potential bottlenecks I might introduce in giving my CPU work. That's just me, though. If you have the need for high-bandwidth, quad-channel, DDR4 memory, then here you go.
Pricing has not yet been announced. That said, a 2x8GB DDR4-4000 (the next category up) of the same brand can be found for around $190 USD. 2x8GB DDR4-4133 (the next category above that) is about $220 USD. While those kits contain half the sticks, 2 vs 4, the new kit might be slightly cheaper per stick than these. That's just speculation, though, until retailers show their stock.

Tagged: TSV, SK Hynix, Samsung, hot chips, hbm3, hbm
Samsung and SK Hynix were in attendance at the Hot Chips Symposium in Cupertino, California to (among other things) talk about the future of High Bandwidth Memory (HBM). In fact, the companies are working on two new HBM products: HBM3 and an as-yet-unbranded "low cost HBM." HBM3 will replace HBM2 at the high end and is aimed at the HPC and "prosumer" markets while the low cost HBM technology lowers the barrier to entry and is intended to be used in mainstream consumer products.
As currently planned, HBM3 (Samsung refers to its implementation as Extreme HBM) features double the density per layer and at least double the bandwidth of the current HBM2 (which so far is only used in NVIDIA's planned Tesla P100). Specifically, the new memory technology offers up 16Gb (~2GB) per layer and as many as eight (or more) layers can be stacked together using TSVs into a single chip. So far we have seen GPUs use four HBM chips on a single package, and if that holds true with HBM3 and interposer size limits, we may well see future graphics cards with 64GB of memory! Considering the HBM2-based Tesla will have 16 and AMD's HBM-based Fury X cards had 4GB, HBM3 is a sizable jump!
Capacity is not the only benefit though. HBM3 doubles the bandwidth versus HBM2 with 512GB/s (or more) of peak bandwidth per stack! In the theoretical example of a graphics card with 64GB of HBM3 (four stacks), that would be in the range of 2 TB/s of theoretical maximum peak bandwidth! Real world may be less, but still that is many terabytes per second of bandwidth which is exciting because it opens a lot of possibilities for gaming especially as developers push graphics further towards photo realism and resolutions keep increasing. HBM3 should be plenty for awhile as far as keeping the GPU fed with data on the consumer and gaming side of things though I'm sure the HPC market will still crave more bandwidth.
Samsung further claims that HBM3 will operate at similar (~500MHz) clocks to HBM2, but will use "much less" core voltage (HBM2 is 1.2V).
Stacked HBM memory on an interposer surrounding a processor. Upcoming HBM technologies will allow memory stacks with double the number of layers.
HBM3 is perhaps the most interesting technologically; however, the "low cost HBM" is exciting in that it will enable HBM to be used in the systems and graphics cards most people purchase. There were less details available on this new lower cost variant, but Samsung did share a few specifics. The low cost HBM will offer up to 200GB/s per stack of peak bandwidth while being much cheaper to produce than current HBM2. In order to reduce the cost of production, their is no buffer die or ECC support and the number of Through Silicon Vias (TSV) connections have been reduced. In order to compensate for the lower number of TSVs, the pin speed has been increased to 3Gbps (versus 2Gbps on HBM2). Interestingly, Samsung would like for low cost HBM to support traditional silicon as well as potentially cheaper organic interposers. According to NVIDIA, TSV formation is the most expensive part of interposer fabrication, so making reductions there (and somewhat making up for it in increased per-connection speeds) makes sense when it comes to a cost-conscious product. It is unclear whether organic interposers will win out here, but it is nice to seem them get a mention and is an alternative worth looking into.
Both high bandwidth and low latency memory technologies are still years away and the designs are subject to change, but so far they are both plans are looking rather promising. I am intrigued by the possibilities and hope to see new products take advantage of the increased performance (and in the latter case lower cost). On the graphics front, HBM3 is way too far out to see a Vega release, but it may come just in time for AMD to incorporate it into its high end Navi GPUs, and by 2020 the battle between GDDR and HBM in the mainstream should be heating up.
What are your thoughts on the proposed HBM technologies?

Early this week at the Intel Developer Forum in San Francisco, California G.Skill showed off new low latency DDR4 memory modules for desktop and notebooks. The company launched two Trident series DDR4 3333 MHz kits and one Ripjaws branded DDR4 3333 MHz SO-DIMM. While these speeds are not close to the fastest we have seen from them, these modules offer much tighter timings. All of the new memory modules use Samsung 8Gb chips and will be available soon.
On the desktop side of things, G.Skill demonstrated a 128GB (8x16GB) DDR4-3333 kit with CAS latencies of 14-14-14-34 running on a Asus ROG Rampage V Edition 10 motherboard with an Intel Core i7 6800K processor. They also showed a 64GB (8x8GB) kit clocked at 3333 MHz with timings of 13-13-13-33 running on a system with the same i7 6800K and Asus X99 Deluxe II motherboard.
G.Skill demonstrating 128GB DDR4-3333 memory kit at IDF 2016.
In addition to the desktop DIMMs, G.Skill showed a 32GB Ripjaws kit (2x16GB) clocked at 3333 MHz running on an Intel Skull Canyon NUC. The SO-DIMM had timings of 16-18-18-43 and ran at 1.35V.
Nowadays lower latency is not quite as important as it once was, but there is still a slight performance advantage to be had tighter timings and pure clockspeed is not the only important RAM metric. Overclocking can get you lower CAS latencies (sometimes at the cost of more voltage), but if you are not into that tedious process and are buying RAM anyway you might as well go for the modules with the lowest latencies out of the box at the clockspeeds you are looking for. I am not sure how popular RAM overclocking is these days outside of benchmark runs and extreme overclockers though to be honest.
Overclocking Innovation session at IDF 2016.
With regards to extreme overclocking, there was reportedly an "Overclocking Innovation" event at IDF where G.Skill and Asus overclocker Elmor achieved a new CPU overclocking record of 5,731.78 MHz on the i7 6950X running on a system with G.Skill memory and Asus motherboard. The company's DDR4 record of 5,189.2 MHz was not beaten at the event, G.Skill notes in its press release (heh).
Are RAM timings important to you when looking for memory? What are your thoughts on the ever increasing clocks of new DDR4 kits with how overclocking works on the newer processors/motherboards?

Tagged: Corsair Dominator Platinum, corsair, ddr4-3200
It will certainly cost you quite a bit to pick up but if you have a need for a huge pool of memory the 64GB Corsair Dominator Platinum DDR4-3200 kit is an option worth considering. The default timings are 16-18-18-36 and the heat spreader and DHX cooling fins keep the DIMMs from heating up, even when Overclockers Club upped the voltage to 1.45V. Part of the price premium is the testing which was done before these DIMMs left the factory, as well as the custom PCB and hand picked ICs which should translate to a minimum of issues running at their full speed or even when overclocked. Pop by to see how this kit performed in OC's benchmarks.
"If I break it down, you get a set of modules that have been through an extensive binning process that hand selects the memory ICs being used on these modules. There is a custom designed, cooling optimized PCB that those memory IC's are mounted to so that we can enjoy a trouble free user experience. The DHX cooling solution on these modules is easily up to the task of keeping the modules cool with minimal airflow. The heat spreader and DHX cooling fins are designed to use convective cooling in the absence of any airflow over the modules."

G.Skill recently updated its high end line of Trident Z DDR4 memory modules to add several new color options. While no new speed tiers are being introduced, the existing DIMMs with brushed aluminum silver colored modules with red and black accents will shortly be joined by new modules with 5 new color schemes including silver modules with white or black top bar accents or black modules with white, yellow, or silver accents.
There is nothing groundbreaking here, but it will certainly make putting together a build based around a particular color or theme a bit easier, and that is their goal as these new DIMMs are aimed at modders and enthusiasts who are the most likely group to be running windowed or open air type systems that can show off the internal hardware.
For those interested, the new colors will be available at the end of May. The memory kits in DDR4 3200 Mhz speeds (16GB to 128GB kits) of all timings will be available in the existing red and all the new color schemes. Users wanting the faster speed memory kits (e.g. DDR4 3400) will be limited to the red, white, and black accents (no orange or yellow top pieces on the heat spreader).

The price of DDR4 continues to come down from the stratosphere and into affordable territory, especially when you look at the kits lower their frequencies to allow you to buy a larger pool of RAM. The Crucial DDR4-2133 32GB kit is an example of this, albeit a strange one as they have opted for two DIMMs as opposed to four. The DDR4-2133 15-15-15-36-2T kit retails for ~$175 and has forgone heatspreaders, not a major problem as they are generally only useful for those who want flashy looking RAM. Unfortunately the price is a bit higher than some of the competition and from Hardware Canucks' testing the DIMMs really do not like to be overclocked. If you are still holding out on upgrading your system solely because of the price of DDR4, do a bit of shopping around as you may be in for a pleasant surprise.
"The Crucial DDR4-2133 32GB memory kit may look unassuming but its combination of huge capacity, good speeds, decent overclocking and a low price make for a perfect combination."

Tagged: Samsung, HBM2, Data Memory Systems
Samsung is ready to roll out the next generation of High Bandwidth Memory, aka HBM2, for your desktop and not just your next generation of GPU. They have already begun production on 4GB HBM2 DRAM and promise 8GB DIMMs by the end of this year. The modules will provide double the bandwidth of HBM1, up 256GB/s of bandwidth which is very impressive compared to the up to 70GB/s DDR4-3200 theoretically offers.
Not only is this technology going to appear in the next genertation of NVIDIA and AMD GPUs but could also work its way into main system memory. Of course these DIMMs are not going to work with any desktop or mobile processor currently on the market but we will hopefully see new processors with compatible memory controllers in the near future. You can also expect this to come with a cost, not just in expensive DIMMs at launch but also a comparible increaset in CPU prices as they will cost more to manufacture initially.
It will be very interesting to see how this effects the overall market; will we see a split similar to what is currently seen in mainstream GPUs, a lower cost DDR version and a standard GDDR version? The new market could see DDRx and HMBx models of CPUs and motherboards and could do the same for the GPU market, with the end of DDR on graphics cards. If so will it spell the end of DDR5 development? Interesting times to be living in, we should be hearing more from Samsung in the near future.

That is no typo, the 8GB Corsair Vengeance LPX kit which Hardware Canucks just reviewed is indeed 4000MHz effective at timings of 19-23-23-45. The small size of the dual channel kit helps keep the MSRP to $225, affordable for what it is and not removing the purchase of a second kit from the realms of possibility. However the question of performance remains, does a DDR4-4000 kit provide noticeable performance improvements or is it simply good for bragging rights for those few with a motherboard that can support it? The results vary, especially when looking at memory timings and CPU overclocks compatible with the memory frequency however it was also clear that this memory could probably go faster ... if you had components that were capable of reaching those frequencies.
"The Corsair Vengeance LPX DDR4-4000 is one of the fastest, highest performance memory kits around but with a capacity of just 8GB, will it be enough for today's applications? "

Earlier this month Corsair released new DDR4 memory kits under its Vengeance LPX brand. The kits come in 32 GB, 64 GB, and 128 GB capacities and come bundled with a 40mm "Vengeance Airflow" RAM cooler.
At the top end, the 128 GB kit comes with eight 16 GB modules clocked at 3,000 MHz and with CAS latencies of 16-18-18-36. At stock speeds it is running at 1.35 volts. Stepping down to the lower capacities gets you faster DIMMs. Corsair has the 64 GB (4 x 16 GB) kit clocked at 3,333 MHz and runs at the same voltage and CAS latencies. The 64 GB kit does come with either black or red heat spreaders as well. Lastly, the 4 x 8 GB (32 GB) Vengeance LPX kit runs off of the same 1.35 volts but is clocked at 3,600 MHz (16-19-19-39 rated latencies). It also comes in black and red SKUs.
The memory kits are available now and are currently priced a bit below their MSRPs at Newegg. The 32 GB kit is $340 and the 64 GB kit is $526. Finally, the 3,000 MHz 128 GB kit will set you back $982. These prices seem more competitive than the last time I looked at DDR4, and there certainly does seem tot be some room for overclocking (especially on that 128 GB kit) so long as the motherboard can handle it!

Though information about the technology has been making rounds over the last several weeks, GDDR5X technology finally gets official with an announcement from JEDEC this morning. The JEDEC Solid State Foundation is, as Wikipedia tells us, an "independent semiconductor engineering trade organization and standardization body" that is responsible for creating memory standards. Getting the official nod from the org means we are likely to see implementations of GDDR5X in the near future.
The press release is short and sweet. Take a look.
ARLINGTON, Va., USA – JANUARY 21, 2016 –JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD232 Graphics Double Data Rate (GDDR5X) SGRAM. Available for free download from the JEDEC website, the new memory standard is designed to satisfy the increasing need for more memory bandwidth in graphics, gaming, compute, and networking applications.
Derived from the widely adopted GDDR5 SGRAM JEDEC standard, GDDR5X specifies key elements related to the design and operability of memory chips for applications requiring very high memory bandwidth. With the intent to address the needs of high-performance applications demanding ever higher data rates, GDDR5X is targeting data rates of 10 to 14 Gb/s, a 2X increase over GDDR5. In order to allow a smooth transition from GDDR5, GDDR5X utilizes the same, proven pseudo open drain (POD) signaling as GDDR5.
“GDDR5X represents a significant leap forward for high end GPU design,” said Mian Quddus, JEDEC Board of Directors Chairman. “Its performance improvements over the prior standard will help enable the next generation of graphics and other high-performance applications.”
JEDEC claims that by using the same signaling type as GDDR5 but it is able to double the per-pin data rate to 10-14 Gb/s. In fact, based on leaked slides about GDDR5X from October, JEDEC actually calls GDDR5X an extension to GDDR5, not a new standard. How does GDDR5X reach these new speeds? By doubling the prefech from 32 bytes to 64 bytes. This will require a redesign of the memory controller for any processor that wants to integrate it.

As for usable bandwidth, though information isn't quoted directly, it would likely see a much lower increase than we are seeing in the per-pin statements from the press release. Because the memory bus width would remain unchanged, and GDDR5X just grabs twice the chunk sizes in prefetch, we should expect an incremental change. No mention of power efficiency is mentioned either and that was one of the driving factors in the development of HBM.

I am excited about any improvement in memory technology that will increase GPU performance, but I can tell you that from my conversations with both AMD and NVIDIA, no one appears to be jumping at the chance to integrate GDDR5X into upcoming graphics cards. That doesn't mean it won't happen with some version of Polaris or Pascal, but it seems that there may be concerns other than bandwidth that keep it from taking hold.

Samsung has just announced that they have begun mass production of 4GB HBM2 memory modules. When used on GPUs, four packages can provide 16GB of Video RAM with very high performance. They do this with a very wide data bus, which trade off frequency for transferring huge chunks. Samsung's offering is rated at 256 GB/s per package, which is twice what the Fury X could do with HBM1.
They also expect to mass produce 8GB HBM2 packages within this calendar year. I'm guessing that this means we'll see 32GB GPUs in the late-2016 or early-2017 time frame unless "within this year" means very, very soon (versus Q3/Q4). They will likely be for workstation or professional cards, but, in NVIDIA's case, those are usually based on architectures that are marketed to high-end gaming enthusiasts through some Titan offering. There's a lot of ways this could go, but a 32GB Titan seems like a bit much; I wouldn't expect that this affects the enthusiast gamer segment. It might mean that professionals looking to upgrade from the Kepler-based Tesla K-series might be waiting a little longer, maybe even GTC 2017. Alternatively, they might get new cards, just with a 16GB maximum until a refresh next year. There's not enough information to know one way or the other, but it's something to think about when more of it starts rolling in.
Samsung's HBM2 are compatible with ECC, although I believe that was also true for at least some HBM1 modules from SK Hynix.
