I'm also stable with the same timings and --rfc 250 which gave me an additional boost. Modified timings would be
--rp 10 --rc 44 --rfc 250 --rrd 3 --rcdrd 12 --rcdwr 5
Thank you for the info.
I will give it another go.
BTW for current version '--rrd 3' should be replaced with '--rrds 3 --rrdl 3' otherwise it won't be set
Edit: Tried it again on my ref V64 Samsung, but same... it crashes after about 1 min.
BTW what's the point in such low rcd if you don't set ras accordingly?
