2004-11-30 / ModRobert: Added xbox v1.6b

NOTE: You can find the original xbox version table at

At this moment there are 8 versions of Xbox. The xbox v1.0 , v1.1, v1.2, v1.3, v1.4, v1.5, v1.6 and v1.6b

IMPORTANT: These tests are just made by examining our xbox consoles and using tips we received from our visitors. There's NO guarantee these test are 100% correct.


Externals checks you can do

(mostly not very accurate, but it should give you an idea of what xbox version you have)

Check the "manufacturing date"

You can even do this when your xbox is still packed 'cause there's a small hole at the back of the xbox package where you can read the serial & manufacturing date.


The manufacturing date (MFG. DATE) is in international format : year-month-day
If the manufacturing date is prior August 2002 : you have a v1.0
If the manufacturing date is August 2002 or later : probably a v1.1 (but v1.0 is still possible (MS factory refurbished)).
If the manufacturing date is December 2002 or later : probably v1.2 or v1.3 (but v1.0/v1.1 is still possible (MS factory refurbished))
If the manufacturing date is 15 July 2003 or later : probably v1.4 (but v1.0/v1.1/v1.2/v1.3 is still possible (MS factory refurbished))
If the manufacturing date is 01 August 2003 or later : probably v1.5 or v1.4 (but v1.0/v1.1/v1.2/v1.3 is still possible (MS factory refurbished))
If the manufacturing date is 19 March 2004 or later : probably v1.6
If the manufacturing date is 13 September 2004 or later : probably v1.6b

Try internal checks ...

Some serial checks

(thanks to Under some circumstances you can find your xbox version with the man. date and serial ... check for up-to-date info.

Check your Xbox bios/kernel version

__NOTE: This test isn't 100% accurate , but under most circumstances it should give an idea of your xbox version__

Only try this test if you have NO modchip installed and NO flashed TSOP== Goto the "settings" option in the XBOX menu and select "Sytem Info". You will see lots of legal text. At the end of the txt you will see something like
K: 1.00.xxxx.01
D: 1.00.yyyy.01
If you don't see this you still have one of the first xbox versions (3944 - USA only) , so it's a v1.0
If the xxxx = 4034 or 4036 or 4627 you probably have a v1.0
If the xxxx = 4817 or 4972 you probably have a v1.1
If the xxxx = 5101 you probably have a v1.2 or v1.3 or v1.4 or v1.5

Internal checks you can do

differences between v1.0/v1.1 and v1.2/v1.3/v1.4/v1.5/v1.6 (you will have to open your xbox)

Power connector

The power connector has a double range of connectors on v1.2/v1.3/v1.4/v1.5/v1.6 , only one on v1.1/v1.0


Compare "d0" area

"d0" and traces nearby are placed the same way on v1.0 and v1.1 , but differently on v1.2/v1.3/v1.4/v1.5/v1.6
Compare the location of the traces and points inside the yellow circle to find out your version. Also note the different number of legs on the onboard bios (top of yellow circle) : xbox v1.0/v1.1 have 20legs on each side of the bios , v1.2/v1.3/v1.4/v1.5 have 16 legs.


Compare onboard bios size

Xbox v1.0/v1.1 have 8Mbit (1024k) bioschips of different brands. Xbox v1.2/v1.3/v1.4/v1.5 have a 2Mbit (256k) bioschip of different brands.


Note the extention: 080T-90 , 8 is for 8mbit (90 is for 90nanoseconds) Note that there are several brands of bios chips on v1.0/v1.1 (Hynix , ST , FUJITSU , ...) that may look a bit different than the one showed above (a Hynix).


Extention here is 020T-90B : 2mbit , 90nanoseconds. Note that there are several brands of bios chips on v1.2/v1.3/v1.4/v1.5 (WinBond , ST , ...) that may look a bit different than the one displayed above (a WinBond).

Other layout changes

There are alot of layout changes on v1.2/v1.3/v1.4/v1.5/v1.6 compared to v1.1/v1.0 , as example the bottom left of the board:


As you can see there are alot of differences. For example "Microsoft" has moved (on v1.0/1.1 it's hidden under those big capacitors) , capacitors moved , ....

Internal checks you can do

differences between v1.0 and v1.1/v1.2/v1.3/v1.4/v1.5/v1.6 (you will have to open your xbox)

Check if there's a FAN on the GPU

If there's a fan on the gpu heatsink (next to cpu) you have a v1.0 , if there's no fan you have a v1.1 OR v1.2 OR v1.3 OR v1.4 OR v1.5 OR v1.6


Check if there's a USB pcb

Open your xbox and check the USB chipset. If it's a separate pcb you have a v1.0 , if it's on the xbox motherboard you have a v1.1 OR v1.2 OR v1.3 OR v1.4 OR v1.5 OR v1.6


Differences between v1.2 and v1.3

v1.2 compared to v1.3

There's no perfect method to see the difference between v1.2 and v1.3 (yet).
The best test we can give atm is and check on the serial#:
Serial Number v1.2 : XXXXXXX 30XXX
Serial Number v1.3 : XXXXXXX 31XXX
Serial Number v1.3 : XXXXXXX 32XXX
We do NOT know if this test is 100% accurate.
If the red number is lower then 30 and NOT a v1.0/v1.1 (see tests above) then it's probably also a v1.2. If 32 it's probably a v1.3, 33 and higher can be v1.3/v1.4/v1.5/v1.6
We also know that all Special Edition (translucent green) xbox consoles are still v1.2.

Differences between v1.0/v1.1/v1.2/v1.3 and v1.4/v1.5

The video output chip (this is NOT the nvidea gpu), located near the video output connector is made by 'Focus' on v1.4/v1.5 and by 'Conexant' on v1.0/v1.1/v1.2/v1.3. The brand of the chip is written on the chip.

Here's an image of the chip like on the v1.0/v1.1/v1.2/v1.3 xbox:


The chip on v1.4/v1.5 is on the same location on the motherboard, but 'Focus' will be written on it instead of 'Conexant'

Differences between v1.0/v1.1/v1.2/v1.3/v1.4 and v1.5

There's no visual method to distinguish a v1.5 from a v1.4.
Xbox v1.5 has power and ground disconnected from LPC.
So you will have to measure if pin 2 (ground) on the LPC-bus is connected to the ground plane (a screw, for example) or not.
If ground on LPC is connected you have a v1.0/v1.1/v1.2/v1.3/v1.4, if not you have a v1.5.


Use a multimeter to check if pin2 (red point on images) is connected with ground (screw plate for example). If pin2 is not grounded you have a v1.5, else you have a v1.0/v1.1/v1.2/v1.3/v1.4
LPC pin 12 is also grounded on v1.0/v1.2/v1.3/v1.4 and not grounded on v1.5.
If you prefer you can also measure 3.3v (LPC pin 9) (xbox must be ON) ... it's dead on a v1.5.

Differences between v1.0/v1.1/v1.2/v1.3/v1.4/v1.5 and v1.6

The v1.6 xbox motherboard have a chip labeled 'Xyclops' above the LPC bus and no TSOP flash available. Xboxes with a manufacture date of 2004-03-19 (or later) are v1.6. 2004-03-11 are still v1.4/v1.5.


Differences between v1.0/v1.1/v1.2/v1.3/v1.4/v1.5, v1.6 and v1.6b

The v1.6b xbox motherboard have RAM circuit labeled Hynix.
