Recently while updating my asrock b450m pro 4 motherboard i broke it, it just loops and never turns on, doesn't show video either, so i'm trying to fix it by programing and changing the bios chip but i don´t know how to find a compatible chip, i took a picture of it and it seems to be the WINBOND 25Q128FWSQ but i already send it to a guy who doesn´t fix it and maybe thats not the original chip. Should i buy this same model WINBOND 25Q128FWSQ ? Where can i find if it's the original one? This is the official page for the motherboard ASRock > B450M Pro4

l'm a Mac user who has built his first PC with the following config: CPU: Ryzen 3 3300x Motherboard: Asrock B450m PRO4-F RAM: Team T-Force Dark 16GB (2x8GB) DDR4 3200MHz CL16 Memory Kit - Red HS (TDRED416G3200HC16CDC01) Graphics: Gigabyte RX570 8 GB SSD: 120 GB Adata HDD: Kingston 500 GB 5400 RPM My computer is repeatedly crashing with a blue screen. Going through some of the posts on this forum, I think it seems to be a RAM issue. While the vendor (T-Force) is on the ASROCK QVL, this particular model of RAM isn't (the QVL supports a 2400 MHz RAM from the same manufacturer. Would underclocking my RAM help? If yes then can someone please link me to a guide for the same?

During the build, something on the motherboard blew as a result of a cable being inserted incorrectly (first build). The system still turns on, but I cannot see my SATA SSD so that I can install windows, I cannot see an error with the settings for the SATA drive and the connection is solid. I cannot see the SATA SSD on either the settings or on the options for where to install windows when I allow the system to try to install I have noticed there is some charring next to the CPU (did not previously notice), it is on the other side of the capacitors that are toward the I/O ports. I do not know what these components are, or if they are related to the issue of not seeing the SATA SSD. Can anyone advise on what these components are and their function?

I have connected the psu to the asrock b450 pro4 and my rtx 2080 ventus and I installed ram into all four slots but when I try to short the power connectors the motherboard won’t power anything not even the psu fan spins. Can anyone help?

This is not a crticism of Ryzen, I'm not that brave! It's just my own experience. Last July I finally felt it was time to upgrade my trusty old i5 2500k. I have a 1660 ti and use my pc for a bit of gaming, World of Tanks and a few strategy games and also for the online degree I'm in the middle of doing so I'm not a power user which is why my 2500k has lasted me so long. After much research based on my "late in life" student's tight budget as well as my useage requirements I had pretty much decided on an i5 9400f on a B360 but the reviews on the Zen2 from AMD when it came out made me feel it was better to stretch the budget. Although the Ryzen 5 3600 was way more than I need it seemed stupid to not spend the extra £100 to get myself a system that would still be quite capable in a few years time. So I bought myself a Ryzen 5 3600 paired with an asrock B450 Pro4 atx mobo. I got 16gb of Corsair Vengeance 3000mhz ram suitable for AM4 platform as that was the closest confirmation I could get for compatibility - asrock still today haven't got a memory QVL for Matisse which is great! I got the build running no problem, got temps under control with an aftermarket cooler but had a lot of BSoD until asrock released their second bios for 3rd gen Ryzen which helped a lot with stability, only got a BSoD about once a week with a few random program crashes thrown in for fun. Not totally stable but I knew that was a downside of being an early adopter and asrock's next bios update (3.60) at the start of August improved things further. Everything seemed great until early November iirc then I began to get endless BSoD's with many different and seemingly random codes which made it great fun trying to figure out the problem. Never did manage to track anything specific down so I did a clean install of windows as I figured that might be the problem given most (not all) of the failure codes seemed like they were related to windows. Chipset drivers I kept up to date, regularly checking AMD's site. By the middle of December I was getting really frustrated with system stability and had tried a few things to check one of the components in my system wasn't causing the problem, luckily I had a spare GPU and a mate lent me the ram from a stable 2700x/B450 system but nothing made a difference, I even tried reinstalling windows on a sata ssd and mechanical HDD in case the M.2 ssd was faulty. I kept going, trying a lot of different bios settings suggested by other people with similar problems and using the RAM calculator but nothing worked and I still had endless BSoD's every half hour or so for seemingly random reasons each time. When asrock finally released the B450 bios with AGESA 1.0.0.4 I thought the solution had arrived and I flashed the bios successfully, rebooted and found I now couldn't get as far as the windows login screen without the system crashing, BSoD, reboot and repeat even with a clean windows install. I'd had enough of this crap by now and after speaking to the retailer they let me RMA the mobo which was returned after testing with no problems found, followed by the cpu which was also tested and found to be fully functional. The mobo was tested with a 2600x and the cpu on an X570 mobo. At this point I was left with a cpu and mobo that it seemed were now somehow incompatible with each other at least as far as windows is concerned. I've been a windows user since ms-dos, I've always really enjoyed troubleshooting in spite of how frustrating it could be but with final Latin exams pressing I really needed a stable system right away so I felt that I was left with only a few options, especially considering my budget. I could sell the asrock B450 and get one of the cheaper X570 boards ending up another £100 down or I could sell the CPU and get a 2700x, breaking even financially. Both these options still left me with a system way more powerful than the old i5 but the downside to me was that I wasn't having the best experience returning to Team Red since my Athlon 64 X2 and there was no guarantee that either of these solutions would work. After a month back on the old Sandybridge I was still deciding what to do when I got an email offering an i5 9400f with an Asus Z390-P for £220 and that swung it for me. I've got a stable system that stays frosty never reaching above 55c and I've sold the 3600 for a slight loss, the mobo is now in a friends 2700x system working fine so overall I just about broke even on the deal. I've got no idea what caused this nightmare experience with Ryzen but I won't be buying Asrock ever again - a smaller company I know but truly awful bios support for anything but their top end boards.
