ASUS grew impatient waiting for Samsung to reach volume production on its 32GB DDR4 UDIMMs, and so the company instead designed a new double capacity DIMM standard. This isn’t a JEDEC standard, but is a standard that has gotten some attention from ZADAK and GSkill, both of whom have made some of the tallest memory modules the world has seen. These DIMMs are 32GB per stick, so two of them give us 64GB at 3200MHz and, after overclocking effort, some pretty good timings. Two of these sticks would cost you about $1000, with the 3600MHz options at $1300. Today, we’ll be looking into when they can be used and how well they overclock.
These are double-capacity DIMMs, achieved by making the PCB significantly taller than ordinary RAM. More memory fits on a single stick, making it theoretically possible to approach the max of the CPU’s memory controller. This is difficult to do, as signal integrity starts to become threatened as the PCB grows larger and more complex.
Our hardware news coverage has some more uplifting stories this week, primarily driven by the steepest price drop in DRAM since 2011. System builders who've looked on in horror as prices steadily climbed to 2x and 3x the 2016 rate may finally find some peace in 2019's price projections, most of which are becoming reality with each passing week. Other news is less positive, like that of Intel's record CPU shortages causing further trouble for the wider-reaching partnerships, or hackers exploiting WinRAR, but it can't all be good.

The best news of the week is undoubtedly the expected and continued decrease in memory prices, particularly DRAM prices, as 2019 trudges onward. DRAMeXchange, the leading source of memory prices in the industry, now points toward an overall downtrend in pricing even for desktop system memory. This follows significantly inflated memory prices of the past few years, which was predated by yet unprecedented low prices c. 2016. Aside from this (uplifting) news topic, we also talk about the GN #SomethingPositive charity drive, AMD's price clarifications on Vega, and WinRAR's elimination of a 14-year-old exploit that has existed in third party libraries in its software.

Extreme Ultra-Violet Lithography is something of a unicorn in the space of silicon manufacturing, and has been discussed for generation upon generation. EUV only recently started seeing any form of use in mass produced products, with Samsung kicking off high-volume efforts recently. Intel has also made progress with EUV, deviating from its choice of DUV lithography for a struggling 10nm process and instead setting sights on a 7nm option. This is our leading news item in the recap today, with RAM price declines following closely behind.

The memory supplier price-fixing investigation has been going on for months now, something we spoke about in June (and before then, too). The Chinese government has been leading an investigation into SK Hynix, Samsung, and Micron regarding memory price fixing, pursuant to seemingly endless record-setting profits at higher costs per bit than previous years. That investigation has made some headway, as you'll read in today's news recap, but the "massive evidence" claimed to be found by the Chinese government has not yet been made public. In addition to RAM price fixing news, the Intel CPU shortage looks to be continuing through March, coupled in news with rumors of a 10-core desktop CPU.

Hardware news for the last week has primarily revolved around re-re-releases of hardware, like NVIDIA's GTX 1060 GDDR5X model and AMD's RX 580-not-580. Both are unimaginative, but worth covering. For its part, AMD's RX 580 is an RX 570, just 40MHz faster. It has the same FPU count as the RX 570, despite being named "RX 580." NVIDIA's launch, meanwhile, is a move from 8Gbps GDDR5 to GDDR5X on the 1060 6GB card, which has previously already been pseudo-re-released as a 3GB model and (now gone) 9Gbps model.
Other hardware news includes reduced RAM pricing, SSD pricing, and more. The show notes are below the embedded video, if you prefer articles.
We've been working hard at building our second iteration of the RIPJAY bench, last featured in a livestream where we beat JayzTwoCents' score in TimeSpy Extreme, taking first place worldwide for a two-GPU system. Since then, Jay has beaten our score -- primarily with water and direct AC cooling -- and we have been revamping our setup to fire back at his score. More on that later this week.
In actual news, though, it's still been busy: RAM prices are behaving in a bipolar fashion, bouncing around based on a mix of supply, demand, and manufacturers trying to maintain high per-unit margins. Intel, meanwhile, is still combating limited supply of its now-strained 14nm process, resulting in some chipsets getting stepped-back to 22nm. AMD is also facing shortages for its A320 and B450 chipsets, though this primarily affects China retail. We also received word of several upcoming launches from Intel, AMD, and NVIDIA -- the RTX 2070 and Polaris 30 news (the latter is presently a rumor) being the most interesting.
Frequency is the most advertised spec of RAM. As anyone who’s dug a little deeper knows, memory performance depends on timings as well--and not just the primary ones. We found this out the hard way while doing comparative testing for an article on extremely high frequency memory which refused to stabilize. We shelved that article indefinitely, but due to reader interest (thanks, John), we decided to explore memory subtimings in greater depth.
This content hopes to define memory timings and demystify the primary timings, including CAS (CL), tRAS, tRP, tRAS, and tRCD. As we define primary memory timings, we’ll also demonstrate how some memory ratios work (and how they sometimes can operate out of ratio), and how much tertiary and secondary timings (like tRFC) can impact performance. Our goal is to revisit this topic with a secondary and tertiary timings deep-dive, similar to this one.
We got information and advice from several memory and motherboard manufacturers in the course of our research, and we were warned multiple times about the difficulty of tackling this subject. On the one hand, it’s easy to get lost in minutiae, and on the other it’s easy to summarize things incorrectly. As ASUS told us, “you need to take your time on this one.” This is a general introduction, to be followed by another article with more detail on secondary and tertiary timings.
Hardware news hasn’t slowed since Computex; in fact, this week has been among the busiest in months, with several news items out of the “Big Three” manufacturers. NVidia has seemingly purchased too many GPUs, according to GamersNexus sources (and verifying other stories), GPU shipments overall are trending downward, Intel’s CEO “resigned,” and AMD is working on Vega 20 and V340 products.
Other news for the week includes smaller items, like Be Quiet! opening a US service center and expanding US operations. Learn more in the video, or find the show notes below:
Despite Computex’s imminence, there are still plenty of pre-show announcements and news items to discuss. This week’s anchor item is the “conversation” that Micron has been having with memory suppliers; specifically, China’s Anti-Monopoly Bureau has discussed DRAM pricing with Samsung and Micron, Hynix likely to follow. Connecting the dots isn’t too hard here, but keep in mind that there’s still nothing confirmed with regard to price fixing possibilities.
Separately, AMD’s B450 chipsets were detailed, passive AM4 coolers debuted, and JPR thinks cryptomining is waning, giving way to more affordable video cards for gamers.
