Gskill 2x16 F4-3600C14-32GTZN cant disable gdm or 4066+ mhz

[bonet69]

Hello, i bought this kit F4-3600C14-32GTZN and im testing two things go further than 4066 mhz (cant boot with more than 4066mhz no matter what fclk is) and the second is disable GDM so i can try CL15 settings.

Currently i have: 1.5v (i can go lower but then i woul need to raise trfc)

Ramtest tested ok for 2700%

Asus B550-F + 5800x.

I dont know if i am at the limit speed for 2x16gb or my board at 4066 since i cant boot with more speed.... (i could go 4200mhz 1:1 with 2x8gb)

Things i have tried for disabling GDM:
ProcODT 40-48
....Setup 56 56 56 / 0 0 0
cad bus 24-20-24-20 / 60-20-20-30 / 60-20-24-24

None of them worked, always getting ramtest error or bsod....

With my last kit F4-3600C16-16GTZN i was stable with GDM off using:
ProcODT 36.9
....Setup 50 50 50
cad bus 60-20-20-30
But this settings aint working for this one....

Try ProcODT 32 or maybe even lower
Also tRCDRD is really hard to get low...
I would just try to lose all main timings completly.

Maybe try somthing like 18-22-22-22-28 and all subtimings AUTO.
Command Rate 2t could also help with higher frequency.

Let the Motherboard train and go from there.
If it will boot, lower your timings again, till it doesn't

It sure could be the maximum for dual rank sticks and your motherboard.

Nothing worked, i think i will cant go further than 4066 on memory with this board so i am done trying hehe

But i would love to get GDM off stable and i have tried many combinations of cad bus without any luck....
