Hello from Taiwan! We’ve achieved running 128GB of DDR5 at an optimal speed of 6000MT/s on the AM5 platform. I discovered affordable A-Die DDR5 modules for around $100 each, and matched them with a budget ASRock 8-layer board for $250. After updating the BIOS to AGESA 1.0.0.7b, I implemented u/buildzoid’s timing settings. My 128GB (four 32GB units) configuration ran smoothly at DDR5-6000 with UCLK=MEMCLK for 24/7. I completed stability checks with Memtest86 (4 passes), LinpackXtreme (33 runs), and AIDA64 (4 hours) without any errors. When trying 128GB at 6400MT/s with timings 32-39-39-28 and UCLK=MEMCLK, the system booted into Windows successfully—but it failed stability tests. If you manage to achieve stable 128GB performance at 6400MT/s with those settings, please share your configuration!

Specs: Processor – AMD Ryzen 9 7950X; Motherboard – ASRock X670E PRO RS (BIOS 1.28.AS01) ($250); Memory – 4x 32GB ATADA XPG LANCER RGB DDR5 AX5U6400C3232G-DCLARWH (Hynix A-Die) ($400).

I'm interested in checking if desync uclk adjustments or other improvements in the new agesa enable faster RAM speeds, even on a quad-rank setup. Try running Quad Rank with higher speeds to see if it works better now.

Notes for replicating the process: Using EXPO/XMP alone didn’t get me running. I had to manually adjust nine memory bus termination settings: ProcOdt = 48Ω, ProcCaDs = 30Ω, ProcDqDs = 34.3Ω, DramDqDs = 34Ω, RttNomWr = RZQ/4 (60), RttNomRd = RZQ/4 (60), RttWt = RZQ/2 (120), RttPark = RZQ/5 (48), RttParkDqs = RZQ/5 (48).

I began at 5400 MT/s and kept it steady. Raised memory speed by 200 MT/s until stable, then went up again in steps of 200 until reaching the system limit (6000, 6200, 6400). Each adjustment took about 8–9 minutes when updating UEFI settings.

If you enable "Memory Context Restore" and "Power Down Enable," you should reach the UEFI within roughly 10 seconds even if no changes were made. In version 1.0.0.7b, without "Power Down Enable" paired with "Memory Context Restore," the system might not power on at all on the second boot.

Here’s the full list of changes I applied (core tuning details omitted):
