Hi all. I cant start my Crosshair VIII Hero with good memory frequency.
My CPU - Ryzen 3600, (GPU - EVGA 2080ti, PSU - bequite dark power pro 1200, fan - dark rock pro 4, ssd - samsung 960 evo m2)
Memory memory that I checked:
- 2*8 KFA2 HOF 3600 xmp (b-die). This kit perfect worked on my old x370 Asrock Taichi at 3733 cl16. On C8H I cat start at 3200 mhz only with cl20 timings
- 2*8 G.Skill Trident Z RGB 16GB DDR4 Kit C17 4000Mhz (F4-4000C17D-16GTZR) from VQL!. Can start only 3000 mhz!
XMP (DOCP) profiles doesn't work on both kit.
I have 3 start attempts, then safe mode with 2133 mhz(
I tryed 1.34, 1.4, 1.5 V on DDR4, 1.1 on DDR4 SOC, all timings and secondary options from Ryzen DRAM Calculator. Fixed manually IB at 1800 and 1866 mhz.
SCM, spread spectrum, LN2 mode is disabled
Checked on all BIOS - latest 1001, then 0901, first 0702.
what else can I do? whait new BIOS\AGESA 22.214.171.124? Return MB to shop? I'm very dissapoint.
