You did read that correctly, the new Trident Z RGB kit consists of eight 16GB DIMMs which should give you more than enough memory to play with in a variety of ways, including a decent sized RAM drive. There are also some smaller kits available as well as different frequencies, something that Ryzen users should take a peek at as AMD's new chip loves fast RAM. They do not specify AMD support but one would expect to be able to utilize these chips. This particular kit sports timings of CL16-18-18-38 and below you can see the sizes, frequencies and timings of the other Trident Z RGB kits.
As the name implies, these DIMMs do indeed have LEDs on them, supporting a wide variety of colours and with a variety of modes so you can have dynamic lighting effects, if that is your desire. You can see a video of them in action below.

Morry just wrapped up a review of the ASUS Strix Z270E Gaming while Hardware Canucks have looked at a different motherboard, the ASRock X370 Taichi. To some, the names might seem similar but they are very different motherboards, the Z270 is for Intel LGA1151 while the X370 is a brand new AMD AM4 board. If you are just getting into building computers, make very sure you know what you are picking up!
ASRock have chosen a unique pattern to decorate the X370 Taichi and that is before you light up the RGB LEDs on the board. This is the first AM4 board Hardware Canucks have seen and it introduces a new look to the UEFI as well as some physical changes to the layout compared to the previous generation of AMD motherboards. Take look for yourself at one of the first reviews of an AM4 board from ASRock.
"AMD's Ryzen processors may have found the ultimate motherboard with ASRock's X370 Taichi. From overclocking to stock performance and features, this board seems to have it all!"

Here Comes the Midrange!
Today AMD is announcing the upcoming Ryzen 5 CPUs. A little bit was known about them from several weeks ago when AMD talked about their upcoming 6 core processors, but official specifications were lacking. Today we get to see what Ryzen 5 is mostly about.
There are four initial SKUs that AMD is talking about this evening. These encompass quad core and six core products. There are two “enthusiast” level SKUs with the X connotation while the other two are aimed at a less edgy crowd.
The two six core CPUs are the 1600 and 1600X. The X version features the higher extended frequency range when combined with performance cooling. That unit is clocked at a base 3.6 GHz and achieves a boost of 4 GHz. This compares well to the top end R7 1800X, but it is short 2 cores and four threads. The price of the R5 1600X is a very reasonable $249. The 1600 does not feature the extended range, but it does come in at a 3.2 GHz base and 3.6 GHz boost. The R5 1600 has a MSRP of $219.
When we get to the four core, eight thread units we see much the same stratification. The top end 1500X comes in at $189 and features a base clock of 3.5 GHz and a boost of 3.7 GHz. What is interesting about this model is that the XFR is raised by 100 MHz vs. other XFR CPUs. So instead of an extra 100 MHz boost when high end cooling is present we can expect to see 200 MHz. In theory this could run at 3.9 GHz in the extended state. The lowest priced R5 is the 1400 which comes in at a very modest $169. This features a 3.2 GHz base clock and a 3.4 GHz boost.
The 1400, 1500, and 1600 CPUs come with Wraith cooling solutions. The 1600X comes bare as it is assumed that users want to use something a bit more robust. The R5 1400 comes with the lower end Wraith Stealth cooler while the R5 1500X and R5 1600 come with the bigger Wraith Spire. The bottom 3 SKUs are all rated at 65 watts TDP. The 1600X comes in at the higher 95 watt rating. Each of the CPUs are unlocked for overclocking.
These chips will provide a more fleshed out pricing structure for the Ryzen processors and provide users and enthusiasts with lower cost options for those wanting to invest in AMD again. These chips all run on the new AM4 platform which are pretty strong in terms of features and I/O performance.
AMD is not shipping these parts today, but rather announcing them. Review samples are not in hand yet and AMD expects world-wide availability by April 11. This is likely a very necessary step for AMD as current AM4 motherboard availability is not at the level we were expecting to see. We also are seeing some pretty quick firmware updates from motherboard partners to address issues with these first AM4 boards. By April 11 I would expect to see most of the issues solved and a healthy supply of motherboards on the shelves to handle the influx of consumers waiting to buy these more midrange priced CPUs from AMD.
What they did not cover or answer would be how the four core products would be presented. Would each be a single CCX and only 8 MB of L3 cace, or would AMD disable two cores in each CCX and present 16 MB of L3? We currently do not have the answer to this. Considering the latency between accessing different CCX units we can surely hope they only keep one CCX active.
Ryzen has certainly been a success for AMD and I have no doubt that their quarter will be pretty healthy with the estimated sales of around 1 million Ryzen CPUs since launch. Announcing these new chips will give the mainstream and budget enthusiasts something to look forward to and plan their purchases around. AMD is not announcing the Ryzen 3 products at this time.
Update: AMD got back to me this morning about a question I asked them about the makeup of cores, CCX units, and L3 cache. Here is their response.
1600X: 3+3 with 16MB L3 cache. 1600: 3+3 with 16MB L3 cache. 1500X: 2+2 with 16MB L3 cache. 1400: 2+2 with 8MB L3 cache. As with Ryzen 7, each core still has 512KB local L2 cache.

Tagged: ryzen, Infinity Fabric, hwbot, FMA3, Control Fabric, bug, amd, AM4
Last week a thread was started at the HWBOT forum and discussed a certain workload that resulted in a hard lock every time it was run. This was tested with a variety of motherboards and Ryzen processors from the 1700 to the 1800X. In no circumstance at default power and clock settings did the processor not lock from the samples that they have worked on, as well as products that contributors have been able to test themselves.
This is quite reminiscent of the Coppermine based Pentium III 1133 MHz processor from Intel which failed in one specific workload (compiling). Intel had shipped a limited number of these CPUs at that time, and it was Kyle from HardOCP and Tom from Tom’s Hardware that were the first to show this behavior in a repeatable environment. Intel stopped shipping these models and had to wait til the Tualatin version of the Pentium III to be released to achieve that speed (and above) and be stable in all workloads.
The interesting thing about this FMA3 finding is that it is seen to not be present in some overclocked Ryzen chips. To me this indicates that it could be a power delivery issue with the chip. A particular workload that heavily leans upon the FPU could require more power than the chip’s Control Fabric can deliver, therefore causing a hard lock. Several tested overclocked chips with much more power being pushed to them seems as though enough power is being applied to the specific area of the chip to allow the operation to be completed successfully.
This particular fact implies to me that AMD does not necessarily have a bug such as what Intel had with the infamous F-Div issue with the original Pentium, or AMD’s issue with the B2 stepping of Phenom. AMD has a very complex voltage control system that is controlled by the Control Fabric portion of the Infinity Fabric. With a potential firmware or microcode update this could be a fixable problem. If this is the case, then AMD would simply increase power being supplied to the FPU/SIMD/SSE portion of the Ryzen cores. This may come at a cost through lower burst speeds to keep TDP within their stated envelope.
A source at AMD has confirmed this issue and that a fix will be provided via motherboard firmware update. More than likely this comes in the form of an updated AGESA protocol.

G.Skill recently announced two new series of DDR4 memory geared towards AMD’s new AM4 platform and Ryzen CPUs. The FORTIS series comes in kits up to 64 GB at 2400 MHz while the Flare X series features kits up to 32 GB at 3466 MHz.
The FORTIS series come in black with graphics on the sides. At launch, there will be kits in 16 GB, 32 GB, and 64 GB capacities clocked at 2,133 and 2,400 MHz. These kits run at 1.2V.
Flare X reportedly uses “carefully selected” IC chips that have been tested and validated for the AM4 platform and Ryzen processors. These kits run at 1.35V out of the box and come in 16 GB, 32 GB, and 64 GB at 3200 MHz with 14-14-14-34 timings or in a 16 GB (2x8GB) kit clocked at 3466 MHz with 16-16-16-36 timings.
It is worth noting that Ryzen officially supports memory up to 3200 MHz without needing to overclock the bus speed using one of eight memory straps/dividers (this is apparently a limitation of the UEFI and not Ryzen's memory controllers). In order to take advantage of DDR4 with higher clocks, you will need to overclock the base clock (which is made easier/possible on motherboards with external clock generators). G.Skill showed two examples using a Ryzen 7 1700 and an Asus Crosshair VI Hero motherboard where they got a 4x16GB kit clocked at 3467MHz (16-16-16-36 CR1) by setting a 25.4 x multiplier and 118.16 MHz bus speed. The other example was DDR4 at 3200 MHz with a multiplier of 28.4 and 119.99 MHz bus speed. It is interesting that they were able to push the bus speed that high while maintaining stability. G.Skill posted two CPU-Z validation screen shots on its news announcement.
G.Skill did not announce pricing, but it did state the new memory kits would be available later this month. Looking around on Newegg, it seems some of the lower speed kits with 4GB DIMMs are available right now but the new kits with higher clocks and 8GB and 16GB DIMMs are not available yet. The less exciting Fortis series does appear to be available though with a 2x8GB 16GB DDR4-2400 priced at $124.99. Even the Fortis series isn’t fully launched yet though since the 2x16GB and 4x16GB kits aren’t listed.

The first images of a mini-ITX AM4 motherboard are here, courtesy of BIOSTAR (via ComputerBase). Part of their second-generation RACING-series of gaming motherboards, BIOSTAR is now the first company to show an AMD Ryzen-capable mini-ITX option with their X370GTN.
Image credit: ComputerBase
There had been mention of an upcoming mITX board for AMD Ryzen CPUs from BIOSTAR, with a (rather low-key) mention of such a product in a recent company press release (“the exciting new RACING X370GTN in the mini-ITX form factor will also be available”), and these images from the company's RACING event are now circulating along with the specs of two different mITX offerings.
Image credit: ComputerBase
There will in fact be two mini-ITX motherboards, with both X370 (shown) and the lower-end B350 chipsets (with the RACING B350GTN). ComputerBase provided slides with specifications (via Zolkorn, Thai language) who covered the BIOSTAR event:
BIOSTAR has not announced availability or pricing of their mini-ITX Ryzen boards yet, but given the pent-up demand for mini-ITX solutions for enthusiast AMD processors (with AM3 conspicuously absent from mITX), this is great news for small form-factor enthusiasts.

What Makes Ryzen Tick
We have been exposed to details about the Zen architecture for the past several Hot Chips conventions as well as other points of information directly from AMD. Zen was a clean sheet design that borrowed some of the best features from the Bulldozer and Jaguar architectures, as well as integrating many new ideas that had not been executed in AMD processors before. The fusion of ideas from higher performance cores, lower power cores, and experience gained in APU/GPU design have all come together in a very impressive package that is the Ryzen CPU.
It is well known that AMD brought back Jim Keller to head the CPU group after the slow downward spiral that AMD entered in CPU design. While the Athlon 64 was a tremendous part for the time, the subsequent CPUs being offered by the company did not retain that leadership position. The original Phenom had problems right off the bat and could not compete well with Intel’s latest dual and quad cores. The Phenom II shored up their position a bit, but in the end could not keep pace with the products that Intel continued to introduce with their newly minted “tic-toc” cycle. Bulldozer had issues out of the gate and did not have performance numbers that were significantly greater than the previous generation “Thuban” 6 core Phenom II product, much less the latest Intel Sandy Bridge and Ivy Bridge products that it would compete with.
AMD attempted to stop the bleeding by iterating and evolving the Bulldozer architecture with Piledriver, Steamroller, and Excavator. The final products based on this design arc seemed to do fine for the markets they were aimed at, but certainly did not regain any marketshare with AMD’s shrinking desktop numbers. No matter what AMD did, the base architecture just could not overcome some of the basic properties that impeded strong IPC performance.
The primary goal of this new architecture is to increase IPC to a level consistent to what Intel has to offer. AMD aimed to increase IPC per clock by at least 40% over the previous Excavator core. This is a pretty aggressive goal considering where AMD was with the Bulldozer architecture that was focused on good multi-threaded performance and high clock speeds. AMD claims that it has in fact increased IPC by an impressive 54% from the previous Excavator based core. Not only has AMD seemingly hit its performance goals, but it exceeded them. AMD also plans on using the Zen architecture to power products from mobile products to the highest TDP parts offered.
The Zen Core
The basis for Ryzen are the CCX modules. These modules contain four Zen cores along with 8 MB of shared L3 cache. Each core has 64 KB of L1 I-cache and 32 KB of D-cache. There is a total of 512 KB of L2 cache. These caches are inclusive. The L3 cache acts as a victim cache which partially copies what is in L1 and L2 caches. AMD has improved the performance of their caches to a very large degree as compared to previous architectures. The arrangement here allows the individual cores to quickly snoop any changes in the caches of the others for shared workloads. So if a cache line is changed on one core, other cores requiring that data can quickly snoop into the shared L3 and read it. Doing this allows the CPU doing the actual work to not be interrupted by cache read requests from other cores.
Each core can handle two threads, but unlike Bulldozer has a single integer core. Bulldozer modules featured two integer units and a shared FPU/SIMD. Zen gets rid of CMT for good and we have a single integer and FPU units for each core. The core can address two threads by utilizing AMD’s version of SMT (symmetric multi-threading). There is a primary thread that gets higher priority while the second thread has to wait until resources are freed up. This works far better in the real world than in how I explained it as resources are constantly being shuffled about and the primary thread will not monopolize all resources within the core.
