Samsung drops prices of DDR4 memory to gain market share

DDR4 memory is yet to become mainstream DRAM technology, but Samsung Electronics is reportedly reducing prices of its DDR4 chips in a bid to gain market share. Samsung’s actions may trigger further drops of memory pricing in the future.
At present DDR4 memory is used only by high-end desktop as well as server microprocessors, whereas mainstream personal computers use DDR3 memory. In the coming months Intel Corp. will release its “Skylake” microprocessors that support DDR4 memory and demand for the latter will inevitably increase. Apparently, Samsung wants to guarantee itself strong positions in the emerging market, which is why it offers DDR4 memory with discounts.

DDR4 prices have been brought down significantly to come closer to DDR3 prices, reports DigiTimes. If Samsung dominates DDR4 shipments, other makers of memory, such as SK Hynix and Micron Technology, may reduce pricing of mainstream DDR3 memory in a bid to sustain their revenue.
DRAM experts believe that in order to ensure high profit margins, mainstream DDR4 memory has to be made using thinner process technologies, such as 20nm. At present only Samsung produces significant amount of DRAM using 20nm process, which is why it can offer discounts on DDR4 to its clients.

KLEVV CRAS 2133MHz 16GB DDR4 Memory Kit Review

Introduction

---

Memory, the most vital part of any computer that gets overlooked the most. There’s not a lot to say about RAM apart from its expensive and very confusing. DDR4, the newest iteration of RAM is currently the fastest version of the consumer RAM, with speeds exceeding 3333MHz. RAM kits now come in a variety of shapes with the basic bare modules, right up to the simply stunning Ripjaws series.
Today we will be looking at the newly introduced KLEVV CRAS memory kit. This has already been released in other parts of the world and consumers are adoring the high-end finish and amazing performance on offer.
KLEVV was established in just 2014 by the parent company Essencore Limited (or just Essencore), but having close ties within the memory community has allowed the company to quickly grasp The CRAS memory modules are an extremely high-end, they are fitted with huge solid metal heat sinks that not only keep these extremely cool, but also provide excellent aesthetics and strengthening properties.
This particular memory kit has an oddly low-speed rating of 2133MHz, which is strange when you consider the competition for this premium kit is the likes of the Corsair Dominator, however they come with an XMP profile that will take these all the way to 3000MHz in a simple BIOS tweak.

“Employing the most current and high-level IT developments, KLEVV, the vanguard of technological advance, brings PC enthusiasts the highly advanced KLEVV Cras DDR4 Memory. Ready to Beat’em Up? Your adventure is just beginning.”

DRAM prices continue to drop despite of looming back-to-school season

Despite of the fact that personal computer makers are now buying dynamic random access memory in a bid to support demand during the back-to-school season, DRAM prices continue to drop. Not only weak demand impacts DRAM prices negatively. All memory makers are transiting to thinner manufacturing technologies and Samsung even introduces new capacities, which means that there will be more DRAM available in the coming months.
“Downside risk to DRAM prices is mounting as inventory levels are rising amid weak set demand,” wrote Romit Shah, an analyst with Nomura Equity Research, in a note to clients, reports Tech Trader Daily.

At press time one 4Gb 1600MHz DDR3 chip cost $2.558 on the spot market, down from $2.913 in late May, based on data from DRAMeXchange. Contract price of a 4Gb DDR3 memory chip is around $2.75, whereas a 4GB DDR3 SO-DIMM costs $24.5, around $3 lower than back in May. One 4Gb 2133MHz DDR4 chip costs approximately $3.589 on the spot market.
The situation remains complicated because all memory producers are transiting to 20nm fabrication process, which means that their per-chip costs are declining. Since Samsung Electronics is producing a huge part of its DRAM using 20nm manufacturing technology and has been decreasing prices to gain market share for some time now, other makers will follow with the same tactics, passing their savings to their customers and decreasing quotes.
Moreover, the situation will get even more complicated when Samsung and SK Hynix start to produce computer memory at their new facilities: the Line-17 fab in Hwaseong, South Korea, and the M14 fab at the company’s complex in Icheon, Gyeonggi Province, South Korea.

Samsung’s Line-17 fab in Hwaseong, South Korea, is capable of producing logic, DRAM and NAND flash memory. The manufacturing facility is capable of 80 thousand of 300mm wafer starts per month. 60 thousand of wafers are expected to be allocated for computer memory. It is expected that by the end of the year the fab will produce around 40 thousand 300mm wafers per month.
SK Hynix’s M14 will start small-scale production in late Q3 or early Q4, 2015. It is expected that it will produce around 10 thousand of 300mm DRAM wafers per month initially.
Micron, with its strict cost control and profit-based strategy, does not have capacity expansion plans for 2015. However, the company is aggressively transitioning to 20nm process technology. Moroever, when two out of three DRAM producers manufacture more memory, prices will inevitably decline because of increased availability.
“In 2H 2015/1H 2016, we see risk that added DRAM capacity from Samsung (Line-17, greatest impact Q3 2015) and SK Hynix (M14) could push out the timeframe for pricing stability to transpire,” wrote Mr. Shah. “Furthermore, supply could grow on 20nm migrations from Micron and SK Hynix in 2H 2015, which also threatens recovery of pricing. Micron’s migration from 30nm to 20nm could yield an incremental ~80% bits/wafer.”

Corsair Launches First Retail 3666MHz DDR4 Memory Kit

We just learned that Corsair has launched the first 3666 MHz DDR4 memory kit! The Corsair Dominator Platinum 16GB (4 x 4GB) 3666 MHz memory kit with CL18 timings in in stock and ready for purchase over at Newegg if you happen to have $1049.99 sitting around. The model number is CMD16GX4M4B3666C18. The timings on this 16GB kit at 3666 MHz are 18-19-19-39 with a voltage of 1.35V.
image: http://www.legitreviews.com/wp-conte...66MHz-DDR4.jpg

The images of the kit up on Newegg show that these modules feature the color bar that matches the Gigabyte X99-SOC Champion motherboard color theme, so it’s likely designed to go with that board. The kit has Intel XMP 2.0 support and should work on Intel X99 and Intel Z170-based motherboards. From what we gather the Intel Z170 platform with it’s dual-channel DDR4 support and Intel Skylake processors will be an excellent memory overclocking platform with motherboard manufactures supporting 3400MHz and 3466MHz right out of the gate and that we’ll be seeing 3666MHz and 3800MHz possible by those that really want to push it. From our understanding new Samsung 4Gb ICs are being used on these new wicked fast memory kits. DDR4 memory quickly hit 3333MHz in the fall of 2014, but hit a wall until these new Samsung ICs have come out with the ability to run at 3666MHz to 3800MHz!

Crucial Ballistix Sport 2400MHz 32GB DDR4 Memory Kit Review

With DDR4 prices being driven down in preparation for the launch of a mainstream chipset supporting the memory type, now can be considered a good time to bag a high density quad-channel kit. Combining a quartet of 8GB DIMMs in a quad-channel configuration with an operating frequency of 2400MHz and CL16 timings, how will Crucial’s Ballistix Sport set of memory perform in our testing?

Sporting (excuse the pun) a metallic silver heatsink stuck onto black PCBs, Crucial’s Ballistix Sport modules are clearly targeting enthusiasts and power users with a caring for aesthetics. Operating voltage for the dual-sided memory chips is 1.20V, so the heatsink is primarily designed for form over function.
A 32GB kit of DDR4 memory is still an expensive investment to gamers and enthusiasts. But to those content creators, 3D modellers, and virtual machine operators who can rapidly gobble up memory resources, a 4x8GB set can make sense over the logical 16GB alternative.

In order to meet the 8GB capacity requirement per DIMM, Crucial squeezes eight DDR4 DRAM chips onto each side of the memory’s black PCB. The chips will be manufactured by Micron given that this is the effective parent company behind Crucial.
The Extreme Memory Profile (XMP) is set to operate at 2400MHz with slightly loser timings than is the norm – 16-16-16-39.

I think that Crucial’s heatspreader design is smart. Two thin strips of metal dissipate what little heat energy the 1.20V DRAM chips output. Knowing that DDR4 memory does not output a significant amount of power and can therefore be cooled with relative ease, Crucial chooses not to extend the heatspreaders above the PCB.
This is a smart move which has significant benefits for users with a large CPU cooler. There is unlikely to be worry of interference given that the motherboard socket positioning and proximity to DIMM banks should be accounted for within the CPU cooler design.
Perhaps the only negative in regard to heatspreader design is the choice of colour. Boutique system builders may struggle to match components or stick to a theme with the metallic silver colouring. That said, the contrast with the black PCB is eye-catching in its own way.

Specifications:

• Model Number: BLS4C8G4D240FSA.
• Compatible with Intel X99 chipset and Haswell-E processors.
• Frequency: 2400MHz (PC4-19200).
• Timings: 16-16-16-39.
• Voltage: 1.20V.
• Quad Channel Kit: 32GB (4x 4GB).
• XMP 2.0 Ready.
• Lifetime Warranty.

Samsung Has Reported To Cut DRAM Output, Which May Lead To Spiking Of Prices

The largest manufacturer of DRAM Samsung is going to cut production of standard RAM in order to focus on the mobile side of things. The tech giant has reported to reduce this quarter’s production by an astounding 30 percent thanks to the large degree of orders the company has received from Apple to incorporate mobile DRAM in to the upcoming iPhones. That being said, we could be witnessing a spike in regular DRAM prices in the foreseeable future.

Increasing Of DRAM Prices Will Stand To Benefit Companies Like Micron And SK Hynix, Which Were Suffering Thanks To Samsung’s Unbeatable Prices

Apple’s original mobile DRAM suppliers were SK Hynix and Micron, but being unable to meet the quota of mobile DRAM has forced the Cupertino tech company to switch its primary mobile DRAM supplier to Samsung. At this current point, it is unknown if Samsung is going to make price cuts in its mobile DRAM prices in order to secure future orders, but CTimes reports that increasing regular DRAM prices will stand to benefit companies like Micron and SK Hynix, which were already suffering due to Samsung’s unbeatable rates.




According to the source, the South Korean tech firm has already given OEM the heads up that at the end of next month, it will begin to ship out US$20.50 to $21 DRAM modules, which have already been recorded as the lowest prices for this quarter. The company will be putting extra amounts of effort in ensuring that quantity of its 8GB LPDDR4 mobile DRAM are at par with companies’ requirements.
Additionally, the extra effort put in could also be able to secure a future for Apple’s next generation mobile products. Samsung and TSMC are already having an extended race to see which company will be able to reach the finish line of the 10 nm FinFET manufacturing process. If Samsung is able to price its mobile DRAM accordingly, then Apple is not the only company where it could secure future partnerships.

Super Talent Updates its DDR4 LRDIMM Module Density to 64GB

Super Talent Technology, a leading manufacturer of NAND Flash storage solutions, announces its 64GB density DDR4 LRDIMM modules.
Super Talent’s quad rank 64GB DDR4 load reduced DIMM modules targeted for server environments which allow more DIMMs per channel to be used in order to take advantage of an increased memory capacity. A buffer chip replaces the register on these modules in order to help minimize loading on a system and increase speeds.

Currently platforms running the Haswell–EP are able to take advantage of these modules and at three DIMMs per channel, bandwidth speed gap is increased while latency tax from increasing the DPC has been reduced. This is the advantage of using LRDIMM because as DIMMs per channel increase, LRDIMM offers the lower latencies because it is able to run at higher speeds.
All modules are quality tested in house and are built to JEDEC standard specifications with high quality components. DDR4 offers modules up to double the density and speed of previous generation’s DDR3 DRAM while using up to 20% less power which makes it a highly efficient solution for enterprise workloads.
Additional information on Super Talent’s 64GB DDR4 LRDIMM module can be here.

Crucial to reveal white DDR4 memory modules for overclockers

Nowadays virtually all makers of mainboards offer motherboards with various exotic colours, including white or even silver. Makers of memory modules have traditionally been more conservative and typically such products come with black heat spreaders and PCBs. However, Crucial, a division of Micron, decided to release something for modders, who plan to build a system with exotic components.
At the upcoming Gamescom trade-show in Cologne, Germany, the company plans to reveal white Crucial Ballistix Sport LT DDR4 memory modules that utilize white printed circuit boards and white radiators. The modules will feature 4GB or 8GB capacities, up to 2400MHz clock-rates and will be available in dual-channel and quad-channel kits, reports TechPowerUp. Like other DDR4 modules for performance enthusiasts, the Crucial Ballistix Sport LT DDR4 will include XMP 2.0 profiles in their serial presence detect and will automatically overclock themselves beyond JEDEC specifications on appropriate platforms.

While clock-rates of the Crucial Ballistix Sport LT DDR4 family do not really impress, they will still become popular among modders, who plan to use white or silver mainboards from Asustek Computer or MicroStar International.
Pricing of the new modules is unknown, but do not expect them to be too expensive.

Review: Corsair Vengeance LPX 16GB DDR4-3200

Introduction

The memory guys are banking on today's launch of the Intel Skylake platform to be a catalyst for increased exposure and sales. If you don't know, the Core i7-6700K and Core i5-6600K processors can make use of DDR4 memory in dual-channel mode. Coinciding with the Intel release is a raft of Z170 motherboards that support said DDR4 RAM.
As you might expect, Corsair has been quick off the mark in providing Skylake-specific DDR4 kits in a wide range of speeds and capacities. Most kits are repurposed from the present X99 chipset lineup that also uses DDR4 and XMP 2.0 settings. Knowing that Skylake processors use dual-channel memory should pave the way for 16GB kits comprised of two 8GB sticks, just as you see with DDR3, but such capacities aren't widely available just yet once speeds exceed 3,000MHz.
In a roundabout way, this is why Corsair has sent us a 16GB (4x4GB) DDR4 3,200MHz C16 kit for review alongside the Core i7-6700K processor. The kit is predominantly designed for the quad-channel X99 platform but also works just fine on Skylake, though do know that a 2x8GB offering, better suited to the new processor, is listed.

Vengeance LPX has been around for the better part of the year, since the launch of the X99 chipset. We're now routinely seeing manufacturers provide 3,000MHz kits without an absurd price premium over JEDEC-specified 2,133MHz memory. Scaling even higher, Corsair has a 3,400MHz offering in the same four-module configuration. Pricing, as you might expect, goes through the roof as you approach the cutting edge of what is currently available.
Back on point, the low-profile Corsair modules look and feel like quality products. The livery and design hasn't changed since last year, and the aluminium heatspreader is provided in black, blue or red to suit a themed build. The company also includes an Airflow fan for enhanced cooling when overclocking farther than the 3,200MHz XMP 2.0 settings.

And Corsair does a reasonable job of marrying speed to latency because the four-stick pack ships with XMP 2.0 timings that install the modules at 16-18-18-36-2T latencies using 1.35V. If for whatever reason the motherboard doesn't take kindly to XMP settings, the modules default to a JEDEC 2,133MHz and 15-15-15-36 timings at 1.2V.
The real question is whether a 50 per cent uptick in potential bandwidth - DDR4-3,200 vs. DDR4-2,133 - is worth the extra expense, particularly on a top-end chip laden with a decent amount of cache. Corsair's four-module 16GB set costs approximately £140 compared to £100 for a limited-volume 2,133MHz pack of two 8GB modules.

Booting up is as easy as setting the XMP 2.0 profile in the Asus motherboard's BIOS and rebooting into Windows. The extra overclocking knobs and whistles on the Skylake processor and Z170 chipset makes it easy to compare different speeds of memory without affecting the core chip frequency.
