[PDG888]

Hi All,

I have a PC everything working perfectly previously with a 9800X3D.

Just purchased a 9950X3D and now issues with C5 Boot code error.

PC Specs.

Gigabyte Aorus Master - Bios F4, Have tried Bios F5b with same issue

CPU - 9950X3D

G Skill Z5 ram 2 X 32gig are on the QVL list - F5-6000J3040G32GX2-TZ5RK

PC will boot with 1 stick of ram in A2, will not boot with 1 stick in B2

will not boot with A2 and B2 populated

Reseated ram numerous times, also reseated CPU, no bent pins.

Anyone else have the same issue or know of a fix ?

All help and info appreciated

I have a similar issue. 

R9 9950X3D was running fine, same RAM as you, with expo enabled. A day after, PC froze and after restart I got code 00, did a cmos reset, then got C5. Tried re-seating it, no changes. Put my 7900X3D in, wokring no problems. Using an Asus Strix X670E-E Gaming with the latest Bios version 2904
