Hi all,
I’m looking for a late-era Socket 3 motherboard with built-in VRM support for 3.3–3.45 V CPUs (DX4 / AMD 5x86 / Cyrix 5x86).
I’m not in a rush — just hoping to find a clean, stable board at a fair price.
Preferred models (but not limited to):
ASUS PVI-486SP3
Biostar MB-8433UUD / UUD-A
FIC 486-GIO-VT2 (the VT2 variant specifically)
Shuttle HOT-433
Soyo 025 / 486I/O2
Chaintech 486SPM / OPTi 895/896 boards
Genoa 486VLG-X4 (with confirmed voltage jumpers)
Requirements:
Must support 3.3/3.45 V CPUs via onboard VRM
Must be working or tested posting
No battery leakage on the PCB (minor trace fixes are fine)
Preferably within the EU (I’m in the Netherlands)
Nice-to-have (not required):
VLB or PCI slots
Manual or jumper chart
Original I/O shield (where applicable)
Not looking for:
Early 5 V–only Socket 3 boards
PCChips / fake-cache variants
Rework projects with heavy Varta damage
OEM-proprietary boards.
I’m looking for realistic Amibay prices, depending on model and condition.
Please feel free to PM me what you have — I’m happy to discuss.
Thanks for reading,
Niels (Netherlands)
