BIOSTAR has launched its AM5-based A620MS motherboard today, bringing a new low-end option for PC users on a budget. Though BIOSTAR has not disclosed what MSRP it the A620MS motherboard will carry, the specifications of the board make it clear that it targets the lowest-end segment of the market, though it makes use of the regular A620 chipset instead of the even less expensive A620A chipset.

The A620MS sports some features typical for mATX A620 boards (which make up the vast majority of current models): two DDR5 DIMM slots that support up to two 48GB sticks, an M.2 PCIe 4.0 slot for SSDs, four SATA III ports, and a PCIe Gen4 x16 slot. The motherboard also has four debug LEDs for diagnosing CPU, RAM, GPU, and booting errors.

Meanwhile the rear I/O features a one gigabit Ethernet port, four USB 3.2 ports, analog audio jacks, two USB 2.0 ports, an HDMI 1.4 port, and DisplayPort 1.2. Though there are some more fully-featured A620 motherboards available with more ports operating at a higher specification, but the rear I/O is more or less par for the course when it comes to A620.

However, there are other things about BIOSTAR’s A620MS that implies it will be quite low-end for an A620 motherboard. It has just eight total voltage regulator modules (VRMs), which appear to be in a 6+2 or 6+1+1 phase configuration. This isn’t as low-end as BIOSTAR could have gone (ASRock offers a 4+1+1 stage board), but it is still very sparing in VRM stages compared to most other A620 motherboards. These VRMs are also not covered by a heatsink, which is also typical for boards in this segment, as they're normally paired with equally chip 65W(ish) chips.

BIOSTAR doesn’t list any official CPU restrictions in either its press release or its specification sheet; instead, the company simply lists the motherboard as compatible with Ryzen 7000 and future Ryzen 8000 processors.

While the market for AM5 motherboards includes plenty of B650(E) and X670(E) models, there’s only a handful of A620 boards in total. On Newegg, there are 14 different motherboards available, and many only differ slightly in respect to things like form factor. The cheapest of these cost $75 to $100, and while BIOSTAR didn’t reveal what price we should expect of its A620MS board, given its specifications, we expect it will land in that same $75 to $100 region.

Asus on Thursday said it has released new versions of UEFI BIOS for DDR5-supporting Intel 600/700-series motherboards that enable support for 64 GB DIMMs. As a result, Asus's latest platforms for Intel's 12^th, 13^th and 14^th Generation Core processors with four slots for DIMM slots can now work with up to 256 GB of DDR5 memory, and motherboards with two DIMM slots can now support up to 128 GB of memory.

To gain support for 256 GB of DDR5 memory using 64 GB unbuffered DIMMs, one needs to download the latest version of UEFI BIOS for one of the Intel 600/700-series motherboards listed at the Asus website.

The list of Asus motherboards with an LGA1700 socket supporting 256 GB of DDR5 memory includes 75 boards based on a variety of Intel's 600 and 700-series chipsets, including Intel Z790, H770, B760, Z690, W680, and Q670. Though taking stock of Asus's larger motherboard offerings, this is still a bit shy of covering all of Asus's LGA1700 motherboards, which is nearly 200 models in total. So 64 GB DIMM support has only come to a fraction of their boards, at least thus far.

Otherwise, it is noteworthy that cutting-edge high-capacity DIMMs, such as 32 GB, 48GB, and 64 GB, are typically not available with the same blistering XMP clockspeeds as some of their lower-capacity counterparts, so equipping an Intel system with 256 GB of memory will come at a cost of peak memory bandwidth, on top of the typical DDR5 2 DIMM Per Channel (2DPC) frequency penalty. In fact, the fastest 48 GB modules currently offered by Corsair and G.Skill (which could be used to build systems with 192 GB of memory) top out at 6600 MT/s and 6800 MT/s, respectively. Meanwhile, for now, there are no Intel XMP 3.0-compatible 64 GB DDR5 modules from these two renowned makers.

Ultimately, the prime market for high-capacity UDIMMs at this time is going to be content creators, data scientists, and other workstation-light workloads that need a quarter-terabyte of RAM, and can justify the cost for the leading-edge DIMMs. Otherwise 16 GB and 32 GB DIMMs are likely to remain the sweet spot for the LGA1700 platform for the rest of its lifecycle.

Finally, it should be noted that Asus is also announcing (or rather, reiterating) support for 64 GB DIMMs on their AM5 motherboards. That said, this support is already baked into that platform and BIOSes, and unlike the Intel boards, a BIOS update is not needed.
