It’s been something of a busy week in hardware and enthusiast related news this past week, even with Apple’s iPhone event and Amazon’s glutenous Amazon Prime Day sales seemingly dictating part of the news cycle. Still, we’ve got a few stories worth talking about, and as ever, we’ve been busy with other coverage here at GN.
It looks like EVGA is among the first vendors to attempt to address the power limit issue for overclockers looking to push the RTX 3080 ever further, as the company has released a new beta VBIOS that raises the power target. Additionally, there are the usual rumblings in the memory market about price drops, a China-designed 7-nm class chip, an interesting vector supercomputer headed for Japan, and Gundam parts branded by ASUS.
At GN, we’ve been continuing our RTX 30-series coverage with a review and teardown of the ASUS RTX 3080 TUF OC, and we looked at Nvidia’s Reflex suite, including its Latency Analyzer and Reflex Low Latency Mode.
As usual, find the news recap and video embed below.
Hardware news returns with a lot to talk about, including our newest charity auction of a unique, rare item: A KINGPIN 2080 Ti PCB (no parts on it -- just the board!) has been listed to benefit Cat Angels Pet Adoptions, a no-kill shelter we work with locally. You can only get these if you visit KINGPIN's lab, so they're special items that we reserve for charity events. This is the second of two we've listed, with the first benefitting wildlife following Australian bushfires. In hardware news proper, we're talking about Intel Z490 10-core CPU overclocking expectations (not stock), ASUS finding a way to automate application of Thermal Grizzly Conductonaut liquid metal, Samsung 3nm process delays, and more.
We saw the yet-unnamed ASUS ROG Strix Helios at Computex 2018, where it landed a spot on our Most Room For Improvement list alongside the other two cases ASUS showed. ASUS doesn’t make cases--the company’s been around for 30 years, so we won’t say it’s never happened, but it’s definitely a rare occurrence. They worked with In Win to create the concept shown off at Computex, but the ASUS x In Win branding has disappeared from the production version and it’s our understanding that In Win is not involved in manufacturing. The Helios has to stand up to extra scrutiny as part of ASUS’ first foray into the case market. The ROG line has a reputation for solid hardware despite the over-the-top gamer branding, so it has big shoes to fill.The case is packed with as many features as possible, necessary or otherwise. The most distinctive is the velcro strap laced over the top panel, ostensibly an “ergonomic and stylish” handle for carrying the system to LAN parties. It helps a little for hoisting the case up on to a table, but this is not the enclosure to bring to a LAN party, even for the rare person that attends more than one per decade. Most of the case’s surface is glass and it weighs 18kg empty. At least the straps and the rails that they’re looped through are massive overkill, tested up to 50kg according to ASUS, so the most likely point of failure is the person lugging it around. The strap is fastened with velcro and can easily be removed before it gets dusty and gross, and we’d recommend doing so, since the case looks perfectly normal without it.
When we first received our sample, the “multifunction cover” over the cutouts to the side of the motherboard was knocked sideways in a way that looked like serious damage, but it was just loose. There was also a mysterious loose screw wedged into it, which we later discovered was from the front panel. The cover slides backwards and forwards to allow room for E-ATX motherboards, and it contains a 2.5” drive mount and built-in GPU braces. The braces are of limited usefulness since they mostly support the edge of the GPU closest to the motherboard, which is already held up by the PCIe slot. The rails for the supports are unpainted to allow the supports to slide up and down and stand out harshly against the black interior. GPU sag is a problem, but one without an elegant solution. The cover functions normally otherwise but offers very little clearance for plugs on the edge of the motherboard, and connecting the SATA cable for our boot drive was difficult.
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.
We previously deep-dived on MCE (Multi-Core Enhancement) practices with the 8700K, revealing the performance variance that can occur when motherboard makers “cheat” results by boosting CPUs out of spec. MCE has become less of a problem with Z390 – namely because it is now disabled by default on all boards we’ve tested – but boosted BCLKs are the new issue.
If you think Cinebench is a reliable benchmark, we’ve got a histogram of all of our test results for the Intel i9-9900K at presumably stock settings:
(Yes, the scale starts at non-0 -- given a range of results of 1976 to 2300, we had to zoom-in on the axis for a better histogram view)
The scale is shrunken and non-0 as the results are so tightly clustered, but you can still see that we’re ranging from 1970 cb marks to 2300 cb marks, which is a massive range. That’s the difference between a heavily overclocked R7 2700 and an overclocked 7900X, except this is all on a single CPU. The only difference is that we used 5 different motherboards for these tests, along with a mix of auto, XMP, and MCE settings. The discussion today focuses on when it is considered “cheating” to modify CPU settings via BIOS without the user’s awareness of those changes. The most common change is to the base clock, where BIOS might report a value of 100.00, but actually produce a value of 100.8 or 100.9 on the CPU. This functionally pre-overclocks it, but does so in a way that is hard for most users to ever notice.
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.
We’re calling this content the “Most Room for Improvement at Computex 2018” content piece. A lot of products this year are still prototypes, and so still have lots of time to improve and change. Many of the manufacturers have asked for feedback from media and will be making changes prior to launch, hopefully, but we wanted to share some of our hopes for improvement with all of you.
Separately, Linus of LinusTechTips joined us for the intro of this video, if that is of interest.
Last month, we published an article detailing the FTC addressing predatory warranty conditions, and in so doing, the FTC notified six companies of infractions violating the Magnuson-Moss Warranty Act. At the time of that writing, the names of the notified companies were not disclosed; however, Motherboard obtained the names via a Freedom of Information Act request, and they are as follows:
There’s a new trend in the industry: Heatsinks. Hopefully, anyway.
Gigabyte has listened to our never-ending complaints about VRM heatsinks and VRM thermals, and outfitted their X470 Gaming 7 motherboard with a full, proper fin stack and heatpipe. We’re happy to see it, and we hope that this trend continues, but it’s also not entirely necessary on this board. That doesn’t make us less excited to see an actual heatsink on a motherboard; however, we believe it does potentially point toward a future in higher core-count Ryzen CPUs. This is something that Buildzoid speculated in our recent Gaming 7 X470 VRM & PCB analysis. The amount of “overkill” power delivery capabilities on high-end X470 boards would suggest plans to support higher power consumption components from AMD.
Take the Gigabyte Gaming 7: It’s a 10+2-phase VRM, with the VCore VRM using IR3553s for 40A power stages. That alone is enough to run passive, but a heatsink drags temperature so far below requirements of operating spec that there’s room to spare. Cooler is always better in this instance (insofar as ambient cooling, anyway), so we can’t complain, but we can speculate about why it’s been done this way. ASUS’ Crosshair VII Hero has the same VRM, but with 60A power stages. That board, like Gigabyte’s, could run with no heatsink and be fine.
We tested with thermocouples placed on one top-side MOSFET, located adjacent to the SOC VRM MOSFETs (1.2V SOC), and one left-side MOSFET that’s centrally positioned. Our testing included stock and overclocked testing (4.2GHz/1.41VCore at Extreme LLC), then further tested with the heatsink removed entirely. By design, this test had no active airflow over the VRM components. Ambient was controlled during the test and was logged every second.
Ahead of CES 2018, ASUS is announcing their ROG bezel-free kit, a way for gamers to augment the visibility of the display bezels within multi-monitor setups. Such a product theoretically offers a seamless display setup; or rather, the imitation of one. The bezel-free kit makes use of vertical lenses affixed to mounting brackets on the top and bottom, that attach the monitors at a 130 degree angle. From there, the lenses use light refraction to essentially wax away the appearance of the bezels. How well this works, or how obtrusive the lenses or mounts are, remains to be seen. Should GamersNexus get a chance to see this up close, we’ll update accordingly.
