Hi
I've since managed to fix the 430VX system, it turned out that it wasn't the VRMs but rather there was a jumper that raised the Vcore voltage by 2.5% and apparently the older P133 could handle it fine, wheras the P233MMX couldn't without becoming unstable! After closing that jumper now it's all fixed.
I've also patched the BIOS of my board to fix the BIOS' 32gb bug (as in, the BIOS would literally crash when detecting hard drives larger than 32gb), I don't have any IDE HDDs on hand to test but we'll see if it works.
Also for some reason I was unable to get the monitor information, SIV had returned a "Error 2 - the specified file is missing" (since my system's locale is set to French) but otherwise I didn't have any bug:

Aside from the BIOS, CPU and the DVD drive (put in a not-so-period-correct-but-beige Pioneer DVD burner in place of the old TSST DVD-ROM drive I had that stuck out like a sore thumb as it had a dark faceplate) nothing much changed, it's still the same machine
Cheers,
