ASRock AMD B550AM Gaming Motherboard Spied

Here is the first picture of a motherboard based on AMD's upcoming mid-range desktop motherboard chipset, the AMD "B550A," the ASRock B550AM Gaming. The board was spied inside a pre-built desktop at a Best Buy store. This is the first time we've seen the mid-range chipset being referenced as "B550A" and not "B550." The "A" may not be part of the motherboard's model name as the "M" denotes Micro-ATX and usually succeeds the chipset model in ASRock's nomenclature. The B550(A) will be an important chipset for AMD as it will enable motherboards priced under the $150 mark that support AMD's 3rd generation Ryzen processor's I/O natively.

While the X570 is an in-house development by AMD, the B550 is sourced from ASMedia, and is expected to be a new version of the "Promontory-LP" silicon. The only thing that sets this chip apart from the 400-series "Promontory-LP" is PCI-Express gen 3.0 certification. The chipset talks to the AM4 SoC over a PCI-Express 3.0 x4 link, and puts out up to 8 PCI-Express gen 3.0 downstream lanes. A 3rd gen Ryzen processor on a B550 motherboard still puts out PCI-Express gen 4.0 connectivity, which means you get one PCI-Express 4.0 x16 slot, and one M.2 slot with PCI-Express 4.0 x4 wiring. The rest of the chipset's I/O will be similar to the 400-series, which includes six SATA 6 Gbps ports, up to two 10 Gbps USB 3.1 ports, up to four 5 Gbps USB 3.1 ports, and eight USB 2.0/1.1 ports. If the AM4 SoC installed is a 3rd gen Ryzen, then you'll get a couple more 10 Gbps USB 3.1 ports. AMD partners could use the opportunity to launch some of the more upscale B550 motherboards with the latest 2.5 GbE wired LAN, and 802.11ax Wi-Fi 6.

Update (16/10): We learn later down in the referenced Reddit thread, including from comments by AMD's Robert Hallock, that the B550A is a rebranded B450 targeted at OEMs. The B550 (non-A) is what is the upcoming chipset detailed in this article.

A Reprieve: Select PC Hardware Exempt of Tariffs on Chinese Imports to the US

The US Trade Representative on Friday granted a reprieve to the increased tariffs being levied at China-imported electronic goods. The exemption, valid for one year until 20th August 2020, includes some products that will be welcome to PC hardware enthusiasts, including motherboards, graphics cards, desktop cases, "mouse input devices" valued over $70, "trackpad input units" valued at over $100, and power supply units that output more than 500 W.

The exempts have come as fruits of requests from US stakeholders in the hardware space; should imports be available only from China (meaning there are no alternate sources of said materials) or if the tariff could cause "severe economic harm", a temporary reprieve on the levies could be sought. And so the exempts were requested, and now granted. Prices paid before the announcement of the reprieve that included the added tax penalties are final; the exemption is only valid for orders after September 20th. This means the 25% increased rates (itself an increase on the initial 10%) on the tax basis are now frozen when it comes to the aforementioned hardware. This means companies no longer have to scramble to source their manufacturing to countries other than China, and that prices increased for end consumers on the basis of the tax increase are now meritless.

Dozens of GIGABYTE Intel 400-series Chipset Motherboards Show Up at the EEC

Intel is inching closer to the launch of its socket LGA1200 mainstream desktop platform based on its 400-series chipset and 14 nm "Comet Lake-S" silicon. The platform provides a forward upgrade path to the company's 10 nm "Ice Lake-S" processors when they come out. "Comet Lake-S" is a derivative of the "Skylake" microarchitecture that's been scaled up to 10 CPU cores, and HyperThreading enabled across the board, with clock speeds pushed to the limits of the 14 nm silicon fabrication process. The TDP of some of these parts is reportedly set as high as 125 W. GIGABYTE is ready with dozens of motherboards for these processors, based on one of five chipsets - Z490, H470, Q470, B460, and H410.

The Intel Z490 Express will be the top-end chipset geared toward gamers and enthusiasts wanting to overclock their processors. The H470 will be a slight step down, and possibly lack multi-GPU and CPU overclocking support. The Q470 is its twin with certain enterprise-relevant features. The B460 is the mid-range chipset, targeting a spectrum of users including gamers who don't overclock their CPU. The H410 will be the entry-level chipset for everyone else. What's interesting about GIGABYTE's list of motherboards filed for regulatory clearance from the Eurasian Economic Commission, is that is looks partial. There are far too few AORUS-branded products.

MSI Announces DDR4 Memory Overclocking World Record @ 5902 MHz on MPG Z390I GAMING EDGE AC Motherboard

MSI today announced that their in-house overclocker Kovan Yang has broken the world overclocking record for DDR4 memory. The record-breaking feat was achieved with a pair of HyperX Predator DDR4 memory modules paired with MSI's MPG Z390I GAMING EDGE AC motherboard, with a little help from liquid nitrogen cooling.

The overclock was achieved with some compromises: the Intel Core i9-9900K processor that powered the system was running in a pared-down configuration with only a pair of active cores, and the DDR4 memory was working in single-channel mode with a single 8 GB stick and highly relaxed timings of 31-63-6363-2. While this isn't usable in your regular machine, that's not the point of these extreme overclocking feats, anyway. The goal is to showcase component quality and stability whilst working way beyond specifications.

ASUS Confirms Existence of X590 Boards for AMD Ryzen CPUs

According to VideoCardz'es sources at ASUS, they have received confirmation that ASUS is working on new motherboards for AMD's unannounced chipset offerings, X590 and possibly even X599.

BIOSTAR formally (officially) enabled PCI-Express gen 4.0 support for four of its socket AM4 motherboard models based on the AMD X470 and B450 chipsets, through BIOS updates. The updated BIOS lets you use PCI-Express gen 4.0 graphics cards on the topmost PCI-Express x16 slot, and the M.2 NVMe slot that's directly wired to the AM4 SoC. The expansion slots that are wired to the chipset are still restricted to PCIe gen 2.0. You will need a 3rd generation Ryzen "Matisse" processor for PCI-Express gen 4.0. Among the motherboards that receive PCIe gen 4.0 support through BIOS updates are the AB45C-M4S (B450MH), the AB35G-M4S (B45M2), the AX47A-A4T (X470GT8), and the AX47A-I4S (X470GTN). The links lead to the BIOS image files on BIOSTAR website, which you use at your own risk.

AMD AGESA 1.0.0.3ABA Buggy, Company Pulls it from Motherboard Vendors

The latest version of AGESA ComboAM4 microcode that enables 3rd generation Ryzen support on AMD 400-series chipset motherboards has been deemed buggy and pulled from motherboard vendors. AGESA ComboAM4 1.0.0.3ABA (not to be confused with 1.0.0.3AB that's being widely distributed), was originally released to fix an application crash noticed with "Destiny 2." The microcode inadvertantly destabilizes PCI-Express on motherboards, with users of ASUS motherboards complaining of stability issues with the latest BIOS updates that include 1.0.0.3ABA.

Peter "Shamino" Tan from ASUS commented that the company was under a tight schedule to push 1.0.0.3ABA out as BIOS updates, and didn't have the time to properly validate it. "We just got told to pull (was undergoing validation prior) 1003 ABA version," he said, adding the root cause of the problem being "that PCIE speed of BXB-C downgraded from gen4 to gen2,..." He comments "so its not surprising that bugs emerge since the source has hidden bugs that only gets unraveled with thorough testing. combine that with trying to get firmwares out in a tight time frame, kinda damn if you do (release firmware quickly) and damn if you dont (dont release firmware quickly) situation." It's interesting to note that in their BIOS update change-logs, quite a few motherboard vendors omit the full version string of AGESA. You may encounter ComboAM4 1.0.0.3AB being referred to simply as "AGESA ComboAM4 1.0.0.3."

BIOSTAR Launches the B365MHC Micro ATX Motherboard

ASUS Begins Enabling Limited PCIe Gen 4.0 on AMD 400-series Chipset Motherboards

ASUS believes that PCI-Express gen 4.0 support on older socket AM4 motherboards based on the AMD 400-series chipset is technically possible, even if discouraged by AMD. The company's latest series of motherboard BIOS updates that expose PCIe Gen 4 toggle in the PCIe settings, does in fact enable PCIe gen 4.0 to all devices that are directly wired to the SoC. These would be the PCI-Express x16 slots meant for graphics, and one of the M.2 slots that has PCIe x4 wiring to the SoC. Below is a list of motherboards scored by Chinese tech publication MyDrivers, which details the extent of PCIe gen 4.0 support across a number of ASUS motherboards based on the X470 and B450 chipsets.

AMD apparently did not explicitly block PCIe gen 4.0 for older chipsets. It merely suggested to motherboard manufacturers not to enable it, since the newer AMD 500-series motherboards are built to new PCB specifications that ensure PCIe gen 4.0 signal-integrity and stability. ASUS wants to leave it to users to decide if they want gen 4.0. If their machines are unstable, they can choose to limit PCIe version to gen 3.0 in their BIOS settings. Among other things, AMD's specifications for 500-series chipset motherboards prescribe PCBs with more than 4 layers, for optimal PCIe and memory wiring. Many of the motherboards on ASUS' list, such as the TUF B450 Pro Gaming, use simple 4-layer PCBs.
