B450 Gaming-ITX/ac CPU query

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I built a Fatal1ty B450 Gaming-ITX/ac with a Ryzen 2400G internal graphics several years ago. I recently flashed to P1.70 bios. It has two DDR4-3200 8Gb sticks. I used Rufus to install Win11 on unsupported CPU. I don't game and wanted to find out the best value CPU to fit the AM4 slot. Would a 5600G or a 5700G work with my DDR4-3200 ram?  If I do upgrade to a new CPU, will my SSD boot drive that has Win11 installed boot? I think I will need to download a new Bios that will allow the mobo to recognize the new CPU. ..Thanks

	5600G/5700G (Cezanne) have better memory controllers than 2400G (Raven), so I see no reason why any RAM working with 2400G would not work with 5700G. I have many B450 Gaming-ITX/ac boards (3), plus two more X470 Gaming-ITX/ac, which are basically the same things with the chipset swapped. All have been great with many different CPUs over time. At the moment, my 5 boards are with 2600, PRO-2200GE, PRO-4650G (B450), and PRO-4350G, 5700X (X470), all with ECC memory (2400 to 3200). If you need the iGPU, R7-5700G or R7-PRO-5750G would be the fastest available for AM4. If you don't need iGPU, there's always the 5950X, but to be honest, I don't think the VRMs on these little boards are going to be happy with 5950X, unless you underclock big time. That kind of defeats the point of buying 5950X, then. 5700X is a great choice in my opinion, if you're going to use dGPU. 5700G is the best choice if you want the iGPU. The G-series and derivatives also have much lower idle power consumption than non-G chiplset based CPUs. If going with 5600G or 5700G, I'd update the BIOS to 4.40, then swap the CPU, and then update again to the latest (10.43 BETA). I don't see any bridge BIOS for these boards. The only quirk I see is, "If the current BIOS version is older than P1.70, please update BIOS to P1.70 before updating this version." But since you're already on 1.70, you're set.
