Hi,
Just got finished with a new build with a B560 but can't get the machine started. The PSC DRAM light is on and no display. Have read elsewhere that some mobos, particularly the 550s have some issues with DRAM and CPU lights being on.
Is it obvious in this case that I've got dud memory£
Ideas to proceed welcome
AsRock B560 Steel Legend
Intel I9-10850
Corsair Vengeance 16GB x 2 (in A2 and B2 slots with RGB working)
Corsair 600W PSU
NVidia 1050Ti GPU
Sunbow 1TB SSD (SATA0)
Deep Cool Matrexx 50 case
Everything else appears to be working: mobo lighting on, DRAM lighting on, USBs seem to work (can hear a usb hdd starting up). All fans working

Did you try a single stick in each of the slots£ It's a little time consuming and tedious, but you'll find out if you have a bad stick, bad slots or both.

Many thanks for you reply.
OK so I did already try some combinations, but on your suggestion found that only the B1 and B2 slots were working.
Done some more digging, installed latest BIOS but still A1 and A2 not working
Next going to look at the CPU and cooler - it has a backplate which read may cause issues
