On am5, these are the settings I'd personally recommend as a starting point (primarily derived from buildzoid ddr5 6000 hynix fallback timings, simply taking the loosest between a or m die since I don't know which this particular memory kit is):
Ddr5 speed set to 6000
uclk div1 mode set to uclk=memclk (mclk will be 3000, uclk will be 3000)
FCLK left on auto (2000)
Voltages:
VSOC 1.25v (if you disable your igpu in bios 1.2v should be possible unless you get unlucky)
DRAM VDD 1.4v
DRAM VDDQ 1.4v
VDDIO 1.4v
VDDP 0.99v (0.95 should be easily possible, but I've heard of very rare anecdotal cases where stability suffers below 1v even at ddr5 6000)
Timings:
tCL 32 (30 easily possible)
tRCDWR 40
tRCDRD 40
tRP 40
tRAS 48 (40 should be possible, but dual rank can sometimes have issues with low tras)
tRC 88
tWR 48
tRFC 512 (if your memory gets exceptionally hot, you might want to raise to 544)
tRFC2 auto
tRFCSB auto
tREFI 40000 (if you memory stays below 60C raise to 50000, if it goes over 65C lower to 30000)
tRTP 16
tRRDL 8
tRRDS 8
tFAW 32
tWTRL 16
tWTRS 6
tRDRDSCL 4
tRDRDSC 1
tRDRDSD 6
tRDRDDD 6
tWRWRSCL 4
tWRWRSC 1
tWRWRSD 8
tWRWRDD 8
tWRRD 4
tRDWR 16
These are a basic starting point that should be perfectly stable unless you really lose the silicon lottery, but make sure to thoroughly stress test your system. Running memtest86 (free) from a flashdrive is good as an initial test to check for obvious hardware defects in all memory chips, but it's not very good at picking up errors due to overclocking. For free stress testing, at a minimum I'd recommend prime95 large ffts (4+hrs, 8+ preferred) and y-cruncher vt3 (4+hrs, 8+ preferred). For additional validation you could try occt memory and cpu+ram large dataset tests, hci memtest, and tm5 (testmem5) with 1usmus and absolut configs.

Buildzoid am5 ddr5 6000 hynix memory timings: https://www.youtube.com/watch?v=dlYxmRc
Important notes on buildzoid timings: DDR5-6000 1:1 mode should have 2000MHz FCLK (the 2033 recommendation was due to an agesa bug), DDR5-6200 1:1 mode should have 2066MHz FCLK, DDR5-6400 1:1 mode should have 2133MHz FCLK; set mem vdd, mem vddq, and cpu vddio voltages to 1.4v instead of 1.35v (to match xmp); at ddr5 6000 for this dual rank kit I'd recommend tras of 52, trc of 92, and trfc of 550 just to be safe (you can leave trfc 2 and 3 on auto), dual rank timings can probably be set to 9 across the board with 8 being easily possible.
If you stick with ddr5 6000 (uclk 3000) and have the igpu disabled, you can probably lower soc voltage to 1.2 volts or potentially lower if you don't get really unlucky, this improves idle power consumption. You can definitely optimize the settings and timings further, this is just a general recommendation of a starting point. As always, make sure to thoroughly stress test your system.
just grabbed that for 127 with the newegg sale, its on slickdeals right now still.
and just grabbed the gigabyte ultra b650i think it maxes at 6400 so figure i'll run it 6000 at cl26 and call it a day
