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 board Cons: - None noted This 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.

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.

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.

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 gets glitchy or jagging does occur. Not all the time but in certain situations but there is no real worry here. SOMETIMES with Ryzen its spiking to max all core overdrive can cause this. Though if it does concern you -then just do the following: Underclock the system. HOWEVER not the way you have heard from so many: Go into Windows power options manager and just set the min and max to 99% of the CPU utilization. This may seem erroneous but believe me when I say the system is faster... Not to mention as a side bonus it is consistently more stable. With alot less stuttering than with PBO So this method so far alleviates that. For example the default Cinebench R20 score for a 3600 is 2802 or so. This system following the above gets a 3152 rating. On the subject of the RAM it also seems to have the widest unofficial ram support. Currently using TeamGroup Elite Plus RAM And though it is not listed as supported for the 3600 it seems to work just fine. This board does have a bad caveat though: Only two RAM slots. If your wanting more than 16/32 GB of RAM. You may be hard pressed to not shell out alot on the memory.

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 thing is that there’s only 2 Slot for RAM but keep in mind that you can always buy more powerful ram at a decent price so it’s honestly not a big deal. The board is great on power consumption and it’s fast so like I said. If you want that budget build that’s still going to hand you some good speed then this board is a good buy

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

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 for it. What's more, I was only able to edit the speeds for case fan 1 no matter what fan was plugged into that header. No option to adjust case fan 2. The BIOS on this thing is needlessly complicated and its features leave much to be desired. I returned this motherboard unsure if it or my hardware was the problem due to a lack of any sort of diagnostic LEDs or speakers. I spent $10 more on an MSI A520M-A Pro, and my PC booted up instantly with zero issues with the RAM or audio. That's how I know that this motherboard is a load of junk, and not my own hardware. You get what you pay for, I guess. Go for MSI: they're a great brand, and I've built several PCs with their motherboards with no issues. Their BIOS is way better and less confusing as well.
