GIGABYTE B550M DS3H

Sitting at the bottom of GIGABYTE's B550 product stack is the B550M DS3H, which is one of just a handful of micro-ATX sized models to choose from. Aimed specifically at the sub $100 market, the B550M DS3H includes support for DDR4-4733 memory, dual M.2 slots and a Realtek Ethernet and audio codec pairing. 

The GIGABYTE B550M DS3H has perhaps one of the funkiest black and grey patterned PCBs from GIGABYTE, with small black heatsinks that feature gold text for contrast. Included is a full-length PCIe 4.0 x16 slot, with another full-length PCIe 3.0 x4 slot, and a single PCIe 3.0 x1 slot. There are four memory slots with support for up to DDR4-4733, and up to a maximum capacity of 128 GB across four available memory slots. For storage is a pair of PCIe M.2 slots, one PCIe 4.0 x4 and the other PCIe 3.0 x4, with four SATA ports with support for RAID 0, 1, and 10 arrays. 

Included on the rear panel is the bare necessities to what an entry-level board should include, with four USB 3.2 G1 Type-A, and four USB 2.0 ports. For users looking to utilize an AMD Ryzen APU, GIGABYTE has included a pair of video outputs consisting of a DVI-D port, as well as an HDMI output, with a PS/2 keyboard and mouse combo port for legacy devices. A single Realtek Gigabit Ethernet controller powers the RJ45 port, while a Realtek ALC887 HD audio codec drives the board's three 3.5 mm audio jacks.

The B550M DS3H has an MSRP of $94 which sets it as the cheapest GIGABYTE B550 model at launch. With its budget controller set including a Realtek Gigabit Ethernet controller and Realtek ALC887, it has all the basics needed for a low-end and entry-level system. It has no Type-C or USB 3.2 G2 connectivity, but that's acceptable for a board in the sub $100 market space.

    That‘s X570. If you need the additional storage bandwidth, this is what you should go for.

    Alternatively there is the Aorus board that offers the 8x CPU plus 2x 4x PCIe 4 lanes for nVMe drives plus the PCIe 3 lanes from the chipset. That could be an alternative and eight PCIe 4 lanes for the GPU should be fine with the next gen GPU, except perhaps for the top of the line models.

    On the plus side, with Ryzen you have four dedicated PCIe lanes from the CPU for nVMe (16+4+4 vs. 16+4 on Intel).

    The X570 goes whole hog on PCI-E 4 with PCI-4 hanging off the chipset too and it supports more PCI-E and SATA and USB devices hanging off the chipset so while the CPU to Chipset bandwidth is higher it's actually even more imbalanced between the combine possible bandwidth of devices possible off the chipset and the CPU to Chipset bandwidth.

    Going PCI-E 4 for just the CPU to Chipset on the B550 would have given the option to decrease that imbalance and one PCI-E 4x link shouldn't have driven the power up too high.

    Then most people wouldn't buy X570 and get B550 instead as there wouldn't be much of a difference. That, and having less PCIe 4.0 stuff lowers the power requirements a bit.

    I personally held off on X570 because I knew I basically only needed the GPU and NVMe drive to be PCIe 4.0 for the most future-proof setup. I figure I'll buy new again when the new AM5 socket is released with Zen 4. Plus, some of the B550 boards have a Type-C front connector, which will go with the new ITX case I'm getting that has one on the front.

    Yes, but then you need to add a separate PCIe controller on the chipset to handle just those 4 lanes. The market probably isn't big enough to make it worthwhile. Reply

    The CPU to GPU link is 16x PCIe 4.0 - that has nothing to do with the chipset.

    Or did you mean something else?

    True, but would that not have brought back the requirement for an actively cooled chipset? That definitely contributes to cost, so it makes sense to cut that from the package.

    Personally, I'm happy that we've finally left PCIe 2.0 behind. Such chipsets still being sold in 2020 is horrific.

    I was hoping to build several B550 APU mITX systems this week, but the lack of a compatible APU has stopped those plans. AMD's decision regarding to use a prior generation micro-architecture for its APUs in addition to their decision regarding AM4 firmware size limits are really colliding to create a missed opportunity here. If the iGPU in the Comet Lake processors was better, I'd be picking up H460 or Q470 boards right now instead. Reply

    My understanding is that the firmware size limit wasn't created by AMD. The motherboard makers could always use firmware chips with a larger capacity. Intel doesn't have this problem since they only support one or two CPU generations per motherboard :-) Reply

    I've read elsewhere that Zen1 processors supposedly had a 128 Mb address limit for UEFI firmware. It sounds suspect, but looking back at early AM4 boards, I don't recall any with either 256 Mb chips or striped 128 Mb chips, so maybe it wasn't simply due to the significant jump in price for 256 Mb chips over 128 Mb ones.

    Likewise, looking to replace my aging 7 year old HTPC with a mATX B550 and a Ryzen 4700G but radio silence from AMD on releasing compatiable APU's for the B550's, We now have the long overdue Budget motherboards but no APU's. Dissapointed. Reply
