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?

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."

Tagged: trident z, gskill, G.Skill Trident Z, ddr4
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.

Tagged: ddr4-4000, corsair, Corsair Vengeance LPX
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? "
