MINISFORUM X1 Lite-255 (Ryzen 7 255) — No POST with 64GB (2×32GB) RAM — anyone else?
Hey all, ran into this after upgrading RAM on my X1 Lite-255 and wanted to check if anyone's hit the same thing.
Original (works fine): 2× Crucial CT16G56C46S5.M8D1 — 16GB DDR5-5600, CL46, 1.1V, single-rank. Total 32GB, fully stable at 5600 MT/s.
New (fails): 2× Crucial CT32G56C46S5.C16FPD — 32GB DDR5-5600, CL46, 1.1V, dual-rank. Same brand/line/speed/voltage/CAS as the working kit.
Results:
- 2×16GB → boots normally, stable
- 1×32GB alone → video works, but Windows loops at "Preparing Automatic Repair"
- 2×32GB → no video output at all, no POST
Already tried: latest BIOS, CMOS clear, 10+ min wait for memory training, reseating modules — no change in any case.
The only difference I can find is rank: the 16GB modules are single-rank, the 32GB ones are dual-rank. Wondering if the board just doesn't handle dual-rank SODIMMs well.
Has anyone gotten 64GB working on this machine, or hit the same issue? What kit ended up working for you?
