AMD Ryzen 5000 Series CPUs with Zen 3 Cores Could be Vulnerable to Spectre-Like Exploit

AMD Ryzen 5000 series of processors feature the new Zen 3 core design, which uses many techniques to deliver the best possible performance. One of those techniques is called Predictive Store Forwarding (PSF). According to AMD, "PSF is a hardware-based micro-architectural optimization designed to improve the performance of code execution by predicting dependencies between loads and stores." That means that PSF is another "prediction" feature put in a microprocessor that could be exploited. Just like Spectre, the feature could be exploited and it could result in a vulnerability in the new processors. Speculative execution has been a part of much bigger problems in CPU microarchitecture design, showing that each design choice has its flaws.

AMD's CPU architects have discovered that the software that relies upon isolation aka "sandboxing", is highly at risk. PSF predictions can sometimes miss, and it is exactly these applications that are at risk. It is reported that a mispredicted dependency between load and store can lead to a vulnerability similar to Spectre v4. So what a solution to it would be? You could simply turn it off and be safe. Phoronix conducted a suite of tests on Linux and concluded that turning the feature off is taking between half a percent to one percent hit, which is very low. You can see more of that testing here, and read AMD's whitepaper describing PSF.

ASRock Rack Puts AMD Ryzen 5000 Series Processor in 1U Short Depth Server

ASRock Rack, a division of ASRock dedicated to server/enterprise products, has today quietly launched a 1U short depth server, equipped with AMD's X570 motherboards, able to accommodate AMD Ryzen 5000 series of processors. The 1U2-X570/2T, as ASRock calls it, features an X570D4I-2T motherboard that is capable of housing any AMD Ryzen and Ryzen Pro 5000 series processor with TDP up to 105 Watts, paired with up to four SO-DIMMs of DDR4 ECC memory. Being a remote desktop/server type of build, the 1U case is not designed to be equipped with any powerful discrete graphics card. There is room for the motherboard, the power supply, and the HDDs located next to the motherboard.

Equipped with an 80-Plus Bronze 265 Watt PSU, the system can handle almost any CPU it is equipped with, two 3.5" drives and two 2.5" 7 mm drives. The motherboard also supports M.2 2280 SSD with PCIe 4.0 protocol support. When it comes to basic graphics output, ASRock Rack has installed an ASPEED AST2500 graphics controller to handle basic video output and display the command line, so you can operate with your server with ease. When it comes to networking, it is equipped with dual RJ45 10 GbE connectors, coming from an Intel X550-AT2 Ethernet controller.

Ryzen 5000 Series Processor Support Comes to ASRock X370 Motherboards in Leaked BIOS Update

When AMD announced its 5000 series Ryzen processors, the company has noted that the new CPUs will be able to operate only on the 500 and 400 series chipsets, with a simple BIOS update. That means that millions of motherboards can install the latest CPUs with no problems. Today, we get to see something that is not a usual thing. ASRock has prepared a BIOS for its X370 Taichi motherboard, and it has been leaked at jzelectronic.de. The newly leaked BIOS is said to bring support for AMD's Ryzen 5000 series of processors codenamed Vermeer. Yes, you are reading that right. ASRock has found a way to bring Vermeer to the unsupported X370 platform.

Although impressive, you must note that the BIOS is in the alpha stage of development, which means that it is enriched with possible bugs and glitches, so it is not recommended for use for now. AMD is against this, and said for Tom's Hardware that "AMD has no plans to enable or support AMD Ryzen 5000 series on AMD 300 series chipsets." That means that ASRock has produced one-off software and it is still a question will the company further develop this new "P6.61" BIOS. You can download it at the jzelectronic.de website but proceed with caution.

GIGABYTE Releases AMD 400 Series Motherboard BIOS Update for Ryzen 5000 Series Support

AMD Radeon Smart Access Memory Coming to 400 Series Motherboards

AMD announced Radeon Smart Access Memory (SAM) alongside the RX 6800 series as a feature to increase video memory available to the CPU. SAM is AMD's implementation of the resizable BAR feature found in the PCI Express specification. AMD Smart Access Memory is only available when using an AMD Ryzen 5000 series process and AMD Radeon RX 6800 series graphics card on a compatible motherboard. The feature was initially advertised as a 500 series motherboard exclusive feature but AMD has recently released the new AGESA v2 1.1.0.0 update which should enable support for SAM on B450 and X470 motherboards with a BIOS update.

AMD to Introduce Adaptive Undervolting to Precision Boost Overdrive for Ryzen 5000

AMD has announced they will be introducing Adaptive Undervolting tools for their precision Boost Overdrive software, available for the latest Ryzen 5000 series CPUs. This feature will be made available come launch of AGESA 1180 on 400-series and 500-series motherboards (estimated availability in early December), and will require a BIOS update to enable at the software level. According to AMD, this tool will dynamically calculate the precise amount of voltage required for a given task, analyzing internal sensors (such as workload, temperature, socket limits) and adapting voltage values on the fly at up to 1000 times a second.

This approach by AMD will bring a new age for CPU undervolting, which usually only allows for users to undervolt their CPU on the basis of the worst-case scenario: usually, the way undervolters work is by incrementally reducing the CPU's voltage and testing for stability via stress applications, gaming, or other specialized applications. This means that the CPU will have adequate juice so as not to fail in these scenarios - but of course, your CPU isn't always (in fact, it's almost never, depending on your specific use-case) using the full CPU processing power; this means that all other workloads where the CPU isn't under 100% utilization still have room for voltage reductions. With AMD's Adaptive Undervolting, this will now become possible.
