I have my 4*16 Gb B-die running at DDR 3800 with my FCLK at 1900 on my 5950 in an MSI B550 Tomahawk Motherboard, and am now trying to tighten the timings but any change I make seems to cause failures within ~10mins in Kahru. I have had to increase ProcODT to 48 to get stable with 1900 FCLK at all settings auto apart from the below which I have manually set:
Spread Spectrum : Disabled
Power Down Mode : Disabled
RTT Nom: RZQ/7
RTT WR: RZQ/3
RTT Park: RZQ/1
(the three RTT values I have taken from Ryzen Calculator)
VDDP: 0.95 V
VDDG (CCD): 1.05 V
VDDG (IOD): 1.05 V
VDIMM: 1.4 V
I have managed to drop tRRDS from 10t to 8t but any other changes are now erroring. Any recommendations please?
