for experimentation I got a pair of adapters that let you install SO-DIMM sticks in full-size DIMM slots.
Just like in this video, Intel systems (Skylake-C236 (ASUS P10S WS) and Haswell-EP-X99 (ASRock X99 WS)) work fine with these adapters (by the look of the pcb my adapters seem to be exactly the same models).
But a Ryzen system (ASRock X470 Taichi/UEFI 3.20/2600X) doesn’t post (0d) (also, just like in the referenced video).
I could even test a standard OEM SK Hynix module that worked fine in a Zen+ laptop (Ryzen 5 3550H) - no luck there.
Is there a “simple” reason why this cannot work with Ryzen motherboards?
In the near future I wanted to check if I could speed up a locked down Coffee Lake-i7 OEM system with no dedicated GPU by swapping the standard DDR4-2666 with -3200 ones, since the iGPU should like the additional bandwith.
Since there is no BIOS access I wanted to use Thaiphoon Burner to alter the G.Skill-3200-Samsung B-die-SO-DIMMs’ SPD so that the higher frequency is “force fed” to the CPU’s IMC after a CMOS reset.
I know that this is possible since I accidentally overclocked an Ivy Bridge laptop by installing Kingston HyperX-DDR3-2133 modules that use that mechanism to “auto-overclock” systems.
Unfortunately Intel seems to have locked software access to the SPD on a firmware level on all DDR4 platforms, so using an existing Ryzen system for the job with these SO-DIMM adapters would have been swell, as a Normie-Pleb I don’t feel competent enough to modify of my Intel C236/X99 systems.
Unfortunately I do no longer have access to that mentioned Zen+ laptop and I don’t have any family or friends that have an AMD-DDR4 laptop.
Since this is also my first post I’d like to say hello - been a news episode watcher for a little while and since I got some nice inspiration from a video recommending used enterprise hardware even as a Normie I signed up here to hopefully find answers to various questions and on patreon to show a little support and gratitude for presenting rather niche content in a way plebs can follow
