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!
