Hello everyone,

I’ve been trying to tune my RAM ever since I built my first PC back in March. I love to tinker and tweak, so naturally I started with PBO – every core has its own curve and that’s been rock-solid for months now.

RAM, on the other hand, has been a completely different story: unpredictable, annoying to recover from when it won’t POST, and very sensitive to BIOS/AGESA changes that can randomly break previously stable settings.

Right now I’ve managed to get what I think is a decent result on a Hynix A-die dual-rank 64 GB kit:

• 2×32 GB DDR5, Hynix A-die, dual rank

• 6000 MT/s, CL30 (EXPO base)

• VSOC: 1.25 V

• DRAM VDD/VDDQ: 1.38 V

• Old AGESA (as shown in the screenshot) – this version lets me run the lower VSOC/DRAM volts pretty comfortably

It’s relatively stable, and the temps are under control, but I don’t feel like I’ve “won” yet. I’d really like to:

• Improve bandwidth and latency a bit more

• Make the setup more efficient (lower volts if possible)

• Push the kit as far as is reasonable for 24/7 use

So I’m looking for guidance from people who’ve spent more time with 2×32 GB Hynix A-die on AM5:

• Which secondaries/tertiaries would you go after next?

• Any recommended ranges for tRFC/tREFI, RRDS/RRDL, WTR/WR, etc. on dual-rank 64 GB?

• Is there a particular AGESA you’d recommend sticking with for this combo, or is it worth moving to something newer and retuning from scratch?

Thanks in advance for any advice or critique!
