You don’t have to open up your Xbox and look at the stamp on the mainboard to find out which revision you have. Using the manufacturing date on the bottom of the console you can easily determine the revision.

Knowing which revision your Xbox is will help when installing third-party modifications but far more importantly, you’ll need this information to determine if the clock capacitor needs to be replaced.

Clock Capacitor

The “clock capacitor” as it’s often called, is a super capacitor that can hold a current long after the power source has been removed. In other words, when your Xbox is unplugged the clock capacitor maintains a couple of volts to feed to the CMOS, saving your settings and the date and time – thus the name.

Xbox revisions 1.0 to 1.5 included a faulty capacitor that can potentially damage your Xbox. If your console revision falls within that range, it’s highly recommended that you replace the capacitor.

Determining the Revision Number

Flip your Xbox upside and you’ll see a sticker with a bar code, numbers, dates, etc. similar to the one below.

It’s the MFG. Date that we’re interested in here.

Using the chart below, look up the manufacturer date to determine your Xbox revision number.

2001 to 2002-071.0
2002-08-18 to 2003-01-251.1
2002-12-01 to 2004-03-151.2

Xbox Revisions

Based on our example MFG Date of 2002-05-24, that would put our model revision in the 1.0 range. As far as that faulty Xbox clock capacitor that was mentioned earlier, this revision is of concern and we’ll want to get it replaced sooner than later. If you have a 1.6 or later revision you wont need to worry about the clock capacitor since those revisions do not contain the faulty capacitor.

How’s your Xbox looking, are you needing a replacement?

2.5V 1.0F Super-Capacitor

Also known as the notorious “Xbox Clock Capacitor”, this capacitor stores enough charge to keep the Xbox clock from resetting while it is unplugged for a short time – similar to a battery.
