Hi, I just bought the ryzen 3700x and setup everything except I cant get my pc to post with 4 dimm slots. The pc lights up but doesn't get to the bios. With 2 dimm slots the pc works perfectly. Ive tested all the ram together separately and they all work perfectly. Re-seated to check all mobo ram slots work and also works. XMP in bios works OK and I'm able to hit 3200mhz as advertised on the Ram. Now all these ram are of the same brand Corsair vengeance 16-18-18-36 3200MHz Also prior to removal these were all functional on my ryzen 1700. I tried to lower clocks with no avail. System specs are Ryzen 3700x Asus Prime b350 plus And the 4 ram dimms which ive mentioned. Could it be the timings? I'm going to try and reseat the cmos for a default configuration even though I've tried default settings already but someone suggested this. If this doesn't work does anyone have any idea? I'm on the latest BIOS available btw.
