ryzen 5950x wont boot with 4 ram sticks, help please

[kei_ayanami]

Hi everyone, So i just bought a new ryzen 5950x cpu but it wont boot if i have 4 ram sticks installed and will only boot with 2 ram sticks installed in slot 1-2, if i plug the ram into slot 3-4 it wont boot up at all, the computer will power on and the fans will spin but nothing happens and once i unplug the rams out of slot 3-4 and only use either 1 or 2 or both 1 and 2 it works fine. 

I've test each ram stick individually and they all work fine.
When i put my old ryzen 3700x back in then i can run all 4 ram slots again and it works fine but it only happens when i have my 5950x installed.
If anyone has encountered this problem or know help to help that would be greatly appricated thanks. 

my setup is 

ryzen 5950x
msi x570 a pro mobo with updated bios - 7C37vHF1(Beta version)
64gig aegis ram 16gig sticks x 4
700watt psu

have you got any overclocking enabled in the bios?  also what spec is the memory (speed, latency etc)

 

You could also try rolling back the bios if it lets you as it might be an issue with the beta bios.

hi evilcloud, no overclocking the spec are rated for 3200mhz its currently running at the default 2133mhz or something, 
if i roll back to bios then i wont be able to use the ryzen 5950x since it wasnt able to boot with that cpu until i updated the bios to the latest one.

Any BIOS from this year should support Ryzen 5000 series, so 7C37vHE should theoretically work with that CPU

You have to clear the cmos every time when switching ram. Internal sub timings change quite a bit.

I agree here with this being a possible issue with the Beta BIOS. I would clear CMOS and install the latest non-Beta BIOS as this could be an issue with the Beta BIOS (It's Beta, so there can be issues to begin with and would never recommend flashing a Beta BIOS unless it has a patch/feature not found on the non-Beta BIOS.)

Asus had nothing but beta bios for my board for months.. some of them were awesome.

i see... ill download the bios just before the latest one thats the beta and see if that works

[kei_ayanami]

ok so i changed my bios to the 1 just before the latest one that was the beta version and still no luck... at this rate i'm considering just buying another 2 single 32gig ram sticks so i can still have my total 64gig of ram...... really annoyed since my $400 worth of 16gig sticks will now be useless...

@kei_ayanami Did you ever resolve this issue? I am having the same problem with my 5950X and 4 sticks of G.Skill 3600 CL14 RAM. With two sticks in the last two slots furthest from the CPU, it works at 3400 with DOCP. But with 4 sticks I get a DRAM error LED and it doesnt even POST.

Hey man sorry late reply, nah I never got it sorted I just settled for 32gigs and gave the other 32gig to my gf she's running my old 3700x which works fine with 64gigs of ram.

 

I think my only choice is to get rid of my 2x16gig and buy 2x32gig sticks of ram and only use 2 out of the 4 ram slots

I ended up getting another CPU and it worked for me.

Boom! Problem solved.

Both 5950X. When I was having issues with the first one not recognizing the memory, a friend lent me his 3000 series CPU, and it also worked instantly with all the memory at max speed. That's how I knew the first CPU was faulty.
