Have the C6H with BIOS 7106 and have 3700X and 4x 8GB Ballistix Sport LT 3200 CL16 E-Die (BLS8G4D32AESBK)
With D.O.C.P everything boots fine. Settings DRAM Boot Voltage to 1.35!
I have checked with DRAM Calculator some better timings. And everything was good with 3200 CL14-16-14-32.
But when i want to 3400 or 3600 settings, with the timings from DRAM Calculator, i ended up with C5 in boot.
Is C5 a problem with voltage?
