It is the only notable motherboard manufacturer that never went along with the trend to give bright or otherwise distinctive colors to various components on a motherboard. Their boards have always retained a conventional appearance.
Supermicro is also one of the last motherboard manufacturers to start making boards that work with AMD processors. They still have not released any consumer/desktop board for any AMD processor and only have a limited range of Opteron-based solutions.
Supermicro is also the only mainstream motherboard manufacturer that has released motherboards for the Itanium 2 platform.
|X1||This character represents the supported Processor/CPU Family supported.|| P = Pentium/CoreDuo/Core2Duo/Core2Quad Family|
X = Xeon Family
O = AMD Opteron Family
|X2||This number represents the motherboard generation and depends on X1 before it.|| X4 = Socket 603, Xeon, 400FSB|
X5 = Socket 604, Xeon, 533FSB
X6 = Socket 604, Xeon, 800FSB
X7 = Socket 771, Xeon, 1066/1333FSB
P4 = Socket 603/478 and Pentium 4, 400FSB and 533/800FSB
P8 = Socket 775, Pentium 4/D, 533/800FSB
PD = Socket 775, Pentium 4/D and Core Duo/2Duo/Quad, 533/800/1066FSB
H8 = Socket 940 AMD Opteron
|X3||This character represents the number of physical processors supported.|| S = Single Processor Support|
D = Dual Processor Support
Q = Quad Processor Support
|X4||This character is used to signify the type of Chipset the motherboard uses (Northbridge)|| A = Greencreek (X7 series)|
B = Blackford (X7 series)
V = Blackford-VS (X7 Series)
T = Tulsa (X7 Series)
M = Mukilteo (PD series)
|X5||This character/number typically represents the onboard storage or bundled storage interface.|| 8 = SCSI|
T = SATA
3 = SAS
U = UIO (Universal I/O)
|+||This + symbol represents a special additional option (or missing option). Currently use of it is very situational.|| X7 Series: + means maximum of 16 memory DIMMs supported|
PD Series: + can mean no IDE connector or for some PDSMx series boards, it means Mulkilteo II Northbridge
So for example...
|X7DB3||Xeon / 7th Generation (Socket 771) / Dual Processor / Blackford Chipset / SAS Support|
