The infamous "Red Ring of Death" (three flashing red quadrants) was a hardware failure specific to the original Xbox 360 models (2005–2008). It indicated a general hardware fault—usually cracked solder joints under the GPU/CPU due to thermal cycling.
| Model | Release | RRoD Risk |
|---|---|---|
| Original "Xenon" (203W/175W PSU) | Nov 2005 | Very High |
| "Zephyr" (HDMI added) | Mid 2007 | High |
| "Falcon" (65nm CPU) | Late 2007 | Moderate |
| "Jasper" (65nm CPU+GPU) | Mid 2008 | Low |
| Xbox 360 S "Slim" | Jun 2010 | None (redesigned) |
| Xbox 360 E | Jun 2013 | None |
Bottom line: If you have a Slim or E model, you will never see the Red Ring of Death.
