Remember staring at MemTest86, over and over and over again?

Those of us a little long in the tooth will have no troubles remembering days of Prime95 and MemTest86 runs proving that your overclock was stable as could be, but fresher enthusiasts may not have had that experience.  MemTest86 was, at one point in the early 2000's, the go to memory interface stability testing software, allowing you to boot straight into a testing mode and skipping your OS altogether.  The interface hasn't changed much, but the hardware sure has!  UEFI booting is now supported and you can test this new type of RAM that we only dreamed of back in 2002.  Check out Overclockers Club for the memories, or to learn about another tool to add to your box of tricks.

"If you have any sort of system stability issues, starting with the memory is generally a good bet. It is often people skip testing system memory for defects or the root cause of a system crash because it is often seen as an unnecessary computer component. In reality, it is one of the most important hardware components in any computer. If your system memory is failing, it can account for random lockups, failed POST screens, and an assortment of strange computer issues."

G.Skill teased new DDR4 memory modules at Computex this year including the mysterious and stylish Trident Z RGB Royal memory. The new memory, of which G.Skill had a single stick on display, features a metallic heatspreader with a mirror finish as well as a crystalized RGB LED light diffuser that manages to make RGB look awesome.

Unfortunately, other than admiring the aesthetics, I have not been able to find any other information on this new RGB Royal series of memory. Hopefully G.Skill will be more willing to spill the beans after the craziness of Computex is over and the memory gets closer to fruition. One thing that is almost certain is that these DIMMs are not going to be cheap!

Now that the inside and outside of your computer as well as the mouse and its mat are glowing away in glorious technicolour, you should not leave yourself out of the show.  Strap on the Aorus H5 headset and become part of the show as you sync your ears with the patterns produced by your other peripherals.  As with the other components the H5 is not just eye candy, the 50mm beryllium magnets in the headset will deliver your ear candy as well. 

Keep an eye out for more from Gigabyte and Aorus.

Some Dell Systems Shipping with 24GB of memory: 8GB DDR4 and 16GB Optane Memory

Subject: Memory, Storage | May 29, 2018 - 04:10 PM |
Tagged: Optane, Intel, g3, dell

Recently I came across an interesting product listing on Dell’s website for its new G3 15” gaming notebook. These are budget-friendly gaming systems with mainstream discrete GeForce graphics cards in them like the GTX 1050 and GTX 1050 Ti. Starting at just $699 they offer a compelling balance of performance and value, though we haven’t yet gotten hands on one for testing.

One tidbit that seemed off to me was this:

dell1.png

Several of these systems list 24GB of memory through a combination of 8GB of DDR4 and 16GB of Optane Memory for caching. A similar wording exists in the configuration page for these machines:

dell2.png

Clicking on the More Info link takes you to the “Help Me Choose” portion of the page that details what system memory does, how it helps the performance of your machine, and how Optane comes into the mix. There is important wording to point out that Dell provides (emphasis mine):

Some systems allow you to add Intel® Optane™ memory, which is a system acceleration solution for the 7th Gen and 8th Gen Intel® Core™ processor platforms. This solution comes in a module format and by placing this new memory media between the processor and a slower SATA-based storage devices ( HDD, SSHD or SATA SSD), you are able to store commonly used data and programs closer to the processor, allowing the systems to access this information more quickly and improve overall system performance.

Mixing DRAM with Intel® Optane™ delivers better performance and cost. For example, 4 GB DRAM + 16GB Intel® Optane™ memory delivers better performance and cost than just 8GB DRAM.

What is the difference between Intel® Optane™ memory and DRAM? Does it replace DRAM?
The Intel® Optane™ memory module does not replace DRAM. It can be, however, added to DRAM to increase systems performance.

If I use Intel® Optane™ memory with an HDD to accelerate my games, game launches and level loads become faster and close to that of an SSD experience, but what about the game play? Is the game play impacted?
Game play will not be that different between an SSD and an HDD based systems since the games in loaded into DRAM during play.

While my initial reaction of this as a clever way to trick consumers into thinking they are getting 24GB of memory in their PC when in reality it is only 8GB holds true, there are a lot of interesting angles to take.

First, yes, I believe it is a poor decision to incorporate Optane Memory into the specification of “memory” in these PCs. Optane Memory is an accelerant for system storage, and cannot replace DRAM (as the FAQ on Dell’s website states). If you have 8GB of memory, and your application workload fills that, having 16GB of memory would be a tremendous improvement in performance. Having 16GB of Optane caching on your system will only aid in moving and swapping data from main storage INTO that 8GB pool of physical memory.

Where Dell’s statements hold true though is in instances where memory capacity is not the bottleneck of performance, and your system has a standard spinning hard drive rather than an SSD installed. Optane Memory and its caching capabilities will indeed improve performance more than doubling the main system memory in instances where memory is not the limiter.

I do hope that Dell isn’t choosing to remove SSD options or defaults from these notebooks in order to maintain that performance claim; but based on my quick check, any notebook configuration that has the “24GB of memory” claim to it does NOT offer an SSD upgrade path.

Though it isn't called out one way or the other in the Dell specifications, my expectation is that they are NOT configuring these systems to use the Optane Memory as a part of the Windows page file, which MIGHT show some interesting benefits in regards to lower system memory capacity. Instead, these are likely configured with Optane Memory as a cache for the 1TB hard drive that is also a required piece of the configuration. If I'm incorrect, this config will definitely warrant some more testing and research.

Where the argument might shift is in the idea of performance per dollar improvements to overall system responsiveness. As the cost of DDR4 memory has risen, 16GB of Optane Memory (at around $25) is well below the cost of a single 8GB SO-DIMM for these notebooks (in the $80-90 range), giving OEMs a significant pricing advantage towards their bottom line. And yes, we have proven that Optane Memory works well and accelerates application load times and even level loads in some games.

But will it allow you to run more applications or games that might need or want more than 8GB of system memory? No.

Ideally, these configurations would include both 16GB of DDR4 system memory AND the 16GB of Optane Memory to get the best possible performance. But as system vendors and Intel itself look for ways to differentiate a product stack, while keeping prices lower and margins higher, this is one of the more aggressive tactics we have seen.

I’m curious what Dell’s input on this will be, if this is a direction they plan on continuing or one that they are simply trialing. Will other OEMs follow suit? Hopefully I’ll be able to get some interesting answers this week and during Computex early next month.

For now, it is something that potential buyers of these systems should pay attention to and make sure they are properly informed as to the hardware configuration capabilities and limits.

Tagged: hyperx, gaming, ddr4, ddr4-2933, RGB, RGB LED

Kingston’s enthusiast-focused HyperX brand recently launched a new set of RGB-equipped DDR4 memory modules that use IR transceivers to sync up the LEDs across all the DIMMs. The aptly named Predator DDR4 RGB memory kits feature stylized angular black aluminum heat spreaders and RGB LEDs along the top edge. The DIMMs use eight 1GB chips along a single side.

HyperX’s new Predator DDR4 modules are compatible with Asus Aura Sync, Gigabyte RGB Fusion, and MSI Mystic Light Sync RGB LED control software. The new kits are available in 8GB, 16GB, and 32GB capacities using one, two, or four 8GB modules. HyperX rates (PDF) the modules at DDR4 2933 MHz with CL15-17-17 timings at 1.35V when using the Intel XMP profile. Out of the box, the modules run at 2400 MHz (CL17) and 1.2 volts, however.

The RGB modules reportedly offer smooth lighting effects with low latencies thanks to the direct module-to-module IR communication keeping everything in sync.

The HyperX Predator DDR4 RGB modules come with a lifetime warranty and have a MSRP of $257 for the 16 GB (2x8GB) kit and $513 for the 32 GB (4 x 8GB) kit. Fortunately, the kits are going for a bit less than MSRP online with the 16 GB RGB kit going for $245.99 and the 32GB RGB kit going for $491.99 or about $20 to $30 over the non-RGB Predator DDR4 3000 MHz offerings.

ADATA Overclocks XPG Spectrix D41 RGB Memory to 5 GHz

ADATA recently announced that it was able to overclock its upcoming XPG Spectrix D41 RGB DDR4 memory to 5 GHz on air cooling. The new Spectrix modules were first shown off at CES 2018 along with phase change cooled Spectrix D80 DIMMs.

20180412_81ced2bfb53fa724720af8867e576047.jpg

Not content to let G.Skill have all the fun, ADATA took its 2132 MHz AX4U470038G19-DR41 memory and pushed it to 5 GHz in dual channel mode with fairly tight timings of 21-26-26-45-2T. They do not mention how much voltage was needed, but the XMP 2.0 profile of 4608 MHz at 19-19-19-39 and 1.45V suggests that likely at least 1.5V was needed. For comparison, G.Skill was able to hit 5007.4 MHz at CL21-26-26-46-2T while ADATA hit 4996.8 MHz at 21-26-26-45-2T (as reported by CPU-z). Both memory manufacturers used a MSI Z370I Gaming Pro Carbon AC motherboard and Intel Coffee Lake Core i7-8700K to achieve their overclocks. ADATA had the processor clocked at 4.3 GHz (100 BCLK x 43x multiplier).

ADATA’s Spectrix D41 memory uses stylized heat spreaders along with RGB LEDs along the top edges. According to ADATA it is using carefully screened Samsung B-die ICs which so far appear to be the best chips out there for DDR4 when it comes to pushing clocks and AMD compatibility. While a retail kit clocked at 5 GHz (at least when XMP is turned on) out of the box is still far off, the increasing number of successful overclocks is promising for enthusiasts that are looking for kits to overclock on their own. I am still waiting for the memory kit makers to demonstrate the 5GHz on air feat with an AMD platform though as so far the attempts have all used an Intel platform. Perhaps once Ryzen 2000 CPUs and X470 motherboards are out we will see what 5 GHz does for Infinity Fabric.

Tom Chan, director at ADATA Technology, was quoted in the press release as stating:

“For us, the next critical step will be working to make this more than just a technological milestone, but something that will be accessible to gamers, overclockers and others, so that they can ultimately benefit from this amazing performance.”

ADATA / XPG have not yet announced pricing for its Spectrix D41 (or D80) kits but hopefully they will be available soon. The Spectrix D41 should be available in up to 16GB per DIMM capacities and up to 4600 MHz with XMP 2.0 profiles. I am curious whether the D80 with its phase change cooler could be overclocked any more than 5 GHz or if that is simply the limits of Samsung’s current generation ICs regardless of cooling method (outside of exotic cooling like lquid helium or liquid nitrogen and needing ludicrous amounts of voltage of course heh).

Corsair is introducing a new special edition DDR4 memory kit called the Dominator Platinum Special Edition CONTRAST. The new individually numbed kits feature a monochrome white a black design with white LEDs. The modules come in 32GB kits comprised of either four 8GB DIMMs or two 16GB DIMMs.

Corsair’s fancy black and pearlescent white special edition memory features 10-layer PCBs, carefully screened Samsung ICs, and DHX (dual-path heat exchange) cooling. The top of the modules hold white LEDs (no RGB here!) to add a bit of glow to your system.

Out of the box, the kits come clocked at 2133 MHz with CAS latencies of 15-15-15-36 and running at 1.2 volts. There is a XMP 2.0 profile that, when activated in the BIOS, bumps things up to 3466 MHz and 16-18-18-36 timings though the speed increase comes at the cost of more power draw at 1.35V.

Screenshot (760).png

The Special Edition Contrast memory would look good in most any build, but especially one that eschews RGB for white lights and a simple color scheme. The refined Dominator Platinum memory comes at a premium price though with the 2x16 GB kit having a MSRP of $439.99 and the 4x8 GB kit hitting $479.99. The four DIMM kit is available now from Corsair and the two DIMM kit is coming soon.

Definitely on the expensive side, but it sure looks nice! What are your thoughts?
