System fails to upload when RAM operates in dual-channel mode
Hello! I’m facing a challenge with my upgrade. I’m trying to switch from a Ryzen 7 2700X to a Ryzen 9 3900X, but my system doesn’t boot up at all. I have two 16GB G.Skill Ripjaws V DDR4-3200 modules set up in dual-channel on an ASRock X470 Gaming K4 board. When I turn it on, only the case fan starts, the motherboard lights come on, then it powers off after a few seconds and never shows any POST codes.
If I swap back the 2700X and keep the RAM in dual-channel (slots 2 and 4), it boots normally. But if I put the 2700X back again with the RAM in single-channel mode—either one stick in slot 2 or both in slots 1 and 2—the system works fine.
I’ve checked for bent CPU pins, cleared CMOS, updated and downgraded BIOS, installed the latest version (even a beta), and even removed storage devices or the PSU. The Power Supply seems sufficient with my 850W model. I tried a spare B450 board with dual-channel RAM and it worked perfectly.
I’m wondering if there’s another way to get this to work without changing the motherboard or going for a full upgrade. Any suggestions would be really helpful! Thanks, Parzi.
Several individuals suggested a time frame of 15 to 30 minutes. My computer required 40 minutes, and others indicated something was amiss. However, I haven’t experienced any problems.
