    Great Drop-In Replacement Motherboard for Ryzen 1700 - B450M-HDV R4.0

    Purchased to replace a blown motherboard for a friend on a Ryzen 1700 system.Pros:- Worked perfectly out of the box with no firmware updates needed- Full support for 1st gen Ryzen CPUs without any messing around- Had all the I/O needed for the build- Solid value for a reliable B450 boardCons:- None notedThis was a great easy replacement that got the system back up and running quickly. Highly recommended if you need a drop-in board for older Ryzen CPUs.Would I recommend? Yes, 5 stars.

    Very good, for a basic board.

    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

    Greta for budget pc build

    I used this for my small pc build and it worked great with no issues I didn’t have to mess with the Bois or deal with any random quirks. Would buy again for another small pc build.

    Sometimes the simplestic is the best.

    Want a motherboard that will support a wide variety of CPU's?Like the 2600 or the 3600 or even the Ryzen 5000 (5600 5800 ect.) series?Well then this is a great choice.THOUGH you will need a CPU of a previous generation to use the 5000 series.And yes you will need to preform the BIOS update.It will not provide great overclocking nor would I recommend it for such.Though doing so may cause it to spike the temperature greatly.We know this is just Precision Boost Overdrive.This the motherboard doesn't really handle it that well.I have seen spikes up to 4200 clock speed on this 3600 and the system g

    Great and reliable

    I’ve had this for about 6 months and I originally bought it to hold me over until I get a better board but this thing is actually really nice, I enjoy it being so cheap and also being a good size that would possibly fit a smaller build. It’s easy to use as well and it has a very simple and comfortable bios menu. I suggest that anyone looking for a budget motherboard that won’t break the bank but also provides a reliable build should buy this. There are a few small things I wish it had like Bluetooth and WiFi but thankfully the router is in my room so I can just connect my Ethernet. Another thi

    Great budget board

    Its good for the price, was able to boot up on the first try without issues. The BIOS UI looks better than I expected given the price point. Build quality is also pretty good for the price. I'm running a 5600x on it and its working well. There's three drawbacks, one is there's only 2 ram slots, the IO shield is a bit flimsy and the VRMs don't have heatsinks which might affect longevity, but these issues won't affect most people

    Spend $10 more and get something that actually works

    Tons of issues out of the box. It made me think there were issues with my other hardware because this was brand new, but nope. I managed to get it to finally boot somehow, but the on board audio was non-functional no matter what driver was installed, and Windows was only using half my RAM. It would restart 3 times after changing anything in the BIOS, and after reseating my RAM, it stopped booting at all. Even after swapping the RAM with another pair that I knew worked. One of my 3 pin case fans was always going at full blast too, with no discernible option to turn off PWM and turn on DC mode f
