RaspberryPi Boards

Hardware versions/revisions

Several different boards have been found probably from different assembly lines, and the following table tries to help you identify your board for better troubleshooting. These differences are being debated on raspberrypi.org on this thread [1]

For what we can see for model B boards there are mainly two versions that differ on the type RAM used, Samsung (S) and Hynix (H).

Note: For Board ver. we used: <model><RAM Maker><production date> (ex.: BS1218 is "Model B, Samsung RAM, 18th week of 2012")

Look for the date of manufacturing printed with the year and week (back side, board edge near LAN connector). In this example year (2012) and week (18th):

Model A:

Board ver.	RAM Chip	USB Chip	C6	F1 / F2 Ref. & Ohm	RG2	Reported issues / Feedback	Front	Back	Seen from	Owner

Model B:
