ASUS ROG Dominus Extreme

motherboard LGA3647 ROG

Picked this up as a “broken” board — seller described it as power cycling once before booting into Windows, Aura RGB acting erratic, and missing chipset drivers. Diagnosed and fixed it myself: updated the ME Engine firmware, installed chipset drivers, and flashed the BIOS.

Ran it as a daily driver for two months without a single issue. Eventually pulled the GPU and SSD to move on to a new build. When I went to fire it back up with a Titan RTX it hung at POST code 00 — turned out to be corrupted CMOS data, cleared with a single button press and it came straight up.

Comes complete with all accessories, most still unopened. Even the coaster is still sealed. One of the most extreme enthusiast boards ASUS ever made, built around the only consumer 28-core CPU Intel ever shipped.

Still in the collection — full teardown and VRM deep-dive on the blog.

DIMM.2 on the ROG Dominus Extreme: The Feature That Almost Killed My RAM — Two DIMM.2 slots, four M.2 drives, and a RAM overheating problem I didn't see coming. The Dominus Extreme's most interesting feature is also its most annoying one.
My First ROG Dominus Extreme Was $300 and I Flipped It — Spring 2024, $300, and an EKWB VRM block included in the sale. Post code 00 resistor problem. Sold it for profit. Buyer fixed it.
The Dominus Extreme Came Back From the Dead — POST code 00, a dead board, an eBay listing, and one button fix.
Why the ROG Dominus Extreme VRM Will Basically Last Forever — 32 teamed IR3555 power stages, a CPU that pulls 400 watts, and barely 12 amps per phase. The Dominus Extreme power delivery is so overbuilt it can't really wear out — here's the math, the board, and why nothing current touches it.
