Whether the issue is with the CPU hardware, the mainboard design (VRM, etc), mainboard BIOS, kernel, or the Prime95 app itself still appears to be an open question.

Based on oscilloscope analysis of the VRM output in a linked thread elsewhere in the comments it looks like the board’s VRM design, or its configuration by the board’s BIOS, may be the most likely suspect.

But there are less-researched reports of similar issues on other boards as well, which makes things a bit more murky.

Given the uncertainties there it may put some people off from buying into the TR/sTRX40 platform in general. But to offer a blanket recommendation to avoid is a bit premature.
