ASRock B450M-HDV R4.0 AM4 AMD Promontory B450 SATA 6Gb/s Micro ATX AMD Motherboard

Bought this during prime week, as I had a leftover 3400g processor from a previous upgrade. The board is smartly laid out, though with very few extras. Only two PCIe expansion slots, with the 16 slot being the bottom one, which gives room to put a good video card in, and still have something for the PCIe 1x slot for something like wireless, which unfortunately this board does not come with.
It only comes with 4 sata slots, 1 NVME slot, and only 2 memory stick slots. But this is fine if you’re using it to replace a board in an older machine that’s like 10+ years or more.
If you need to put a zen3 or higher generation processor in this board, you’ll likely need to update the bios.
I would not recommend putting any processor in that goes beyond 95W.
It’s not a great board, but not bad either. It’s good for low end upgrades.

Works great OOTB with AMD Ryzen 5 5500GT.

Bought this to make a PC for daughter, price is so good and I was really happy with its quality. Even considering buying another just for a bench setup for testing. I believe this is my first ASRock board and I have to say, I’ll try more.

Decent MOBO for the price. I use ethernet and wireless devices so no wifi and BT wasn’t a deal breaker. You can Overclock your CPU but wouldn’t recommend it for this MOBO. Only 1 M.2 which sucks but at least it was Gen 3. Mine also came with BIOS 10.10 so it was Ryzen 5000 ready. Currently running a 5600 + 6650 XT and couldn’t be happier with performance.

I had a prior build since early 2020, with an Antec PSU that shorted out recently and died with a bang, and in the process killed the motherboard (MSI). Fortunately, my M.2 NVMe Intel disc (with Windows 11 Pro) was intact, and I did not know then about the CPU (Ryzen 5 3400G Picasso) or RAM (16GB Crucial Ballistix 8GBx2). Typically, a PSU outputs first to the MOBO and CPU, and next to the RAM. Older memories were notoriously susceptible to current and used to die with the MOBO. Fortunately, things have gotten better. Antec was great in sending me a new replacement PSU under warranty. I needed a new replacement MOBO and wanted to stick with AM4 chipset without spending a lot. I found this board on Amazon at a great price, and the several positive reviews were encouraging. Throughout the years, I had always used MSI boards for my builds, except once (ASUS). This was my first experience with ASRock, and I am very pleased so far. The box I received states “AMD Ryzen Desktop 2000 Ready” and had an added sticker “AMD Ryzen 5000 Desktop Ready”, and another “Windows 11 Ready”. I imagine some (older) stock did not have the added (Ryzen 5000) sticker, which would explain some reviewers who had to update the Bios using an earlier generation CPU. When I received it, I did a minimal basic build outside the case, with the new PSU and tested my old CPU and RAM. It booted into BIOS and I was so relieved that the CPU and RAM were fine. I then put the Intel NVMe disc, placed the board in the case, hooked my old Plextor DVDRW, case fans and all the headers. Windows 11 Pro loaded up and all is good. The Bios/set up on this ASRock board is very easy to navigate and has a lot of ‘AUTO’ settings in the default parameters, and I only had to change few things. For the technically savvy, there are several settings you can adjust, but for most people, you will only need the boot menu, particularly for Win 11, and very few advanced configurations. I did not even use the included support CD. The box contains the MOBO, CD, Installation guide, 2 SATA cables, a small M.2 screw and the I/O shield. The guide and illustrations are very adequate. It has 2 DIMM slots (288 pin) and supports up to 64GB, 32GBx2, per ASRock. I bought new 32GB RAM (16GBx2) which was easily recognized. ASRock states for Picasso, the frequency is 2667/2933, but the new memory is 3200 and runs as such, with or without XMP. I am not a gamer and never overclock a CPU and don’t use a discrete GPU anymore. It has on board USB2 (x2) and USB3 headers. The CPU connector is only 4 pin and if you have an 8-pin cable (4+4), you just split it. The MOBO is the standard 24 pin. There are 2 chassis fan connectors (4 pin and 3 pin), 4 SATA connectors, HD audio and a standard front panel system header. There is one M.2 and 2 PCI slots. The I/O shield is as shown (Single PS2, but supports Y-splitter, 2 USB2, 4 USB3, Gigabit LAN, rear audio, VGA, DVI and HDMI). It is a basic board (No WIFI, BT, M-Flash, USB C) and is very well priced. As such, I would recommend as a budget motherboard. Even though I am biased toward MSI boards (I guess force of habit), I will definitely keep this motherboard in mind. Thank you.

I bought a second one to upgrade an older computer (Athlon A6 APU and FM2+ socket MOBO). It also had the Ryzen 5000 and Windows 11 ready stickers. Very satisfied, just like the first time. Recommend. Thank you.
