Console Model Number Decoder

Every console carries a model code on its regulatory sticker, and that code tells a story: which hardware revision it is, when it was built, what changed inside, and which known faults to watch for. Type a code like CUH-1216A or AGS-101 into the decoder — a code that is not listed individually resolves to its series — or browse the full revision tables for each console family below.

Version 1.0 Original Xbox, board A38727-009 Jan 2001 - Oct 2002 Conexant video encoder; 1MB TSOP BIOS chip; USB controller daughterboard (a unique visual identifier); Dedicated GPU cooling fan Leaky clock capacitor, common to all pre-1.6 boards; Thomson DVD-ROM drives prone to laser failure
Version 1.1 Original Xbox, board A38727-009 Aug 2002 - Jan 2003 USB daughterboard removed, controllers wired directly; Single larger heatsink, no fan; MCPX chip revised 1.0 to 1.1 Same clock-capacitor leak risk as v1.0
Version 1.2 Original Xbox, board A38727-012 ('Xblade') Dec 2002 - Mar 2003 New PCB; 2-row 20-pin PSU connector replaces the earlier 1-row connector; BIOS TSOP shrunk to 256KB; XGPU revised to XGPU-S Clock-capacitor leak risk continues
Version 1.3 Original Xbox, board A38727-012 Mar - Aug 2003 Visually near-identical to v1.2; LFRAME trace disconnected from LPC pin 3, which hindered early modchips Clock-capacitor leak risk continues
Version 1.4 Original Xbox, board A38727-012 Aug 2003 - Apr 2004 Video encoder changed from Conexant to Focus Listed among the worst offenders for leaky Nichicon power-rail capacitors near the PSU connector, causing video glitches or a total no-boot
Version 1.6 Original Xbox, board X01063-121 ('Tuscany') Mar/Jun 2004 onward TSOP BIOS chip removed entirely — BIOS/SMC moved onto a custom 'Xyclops' chip; New Xcalibur video encoder; RAM upgrade pads removed Clock caps are less prone to leaking, but if they do fail the console won't boot at all (earlier boards still boot with a failed cap); Xcalibur encoder bug causes some games to render incorrectly in 480p
Version 1.6b Original Xbox, board X01063-121 Sept 2004 - Aug 2005 Identical PCB to v1.6 but with Hynix-brand RAM chips instead of Samsung, different RAM timings Same 480p Xcalibur-encoder bug and no-boot-on-capacitor-failure risk as v1.6

Where this data comes from

Model data compiled from psdevwiki.com (GNU FDL 1.2), consolemods.org and manufacturer documentation. Model numbers are the codes printed on the console's regulatory sticker, usually on the bottom or back of the unit. Regional suffixes (the digits or letters after the base code) indicate the sales region and do not change the hardware revision. If a model number is missing here, it was left out rather than guessed — the table only lists codes verified against documented sources.
