Board D850MD/D850MV Specification Update 

for the most up-to-date list of 

supported processors for these boards. 

The D850MD and D850MV boards support a single Pentium

4

 processor (in a 

478-pin socket) with a system bus of 400 MHz.  The D850MD and D850MV 
boards support the processors listed in Table 5.  All supported onboard memory 
can be cached, up to the cachability limit of the processor.  See the processor’s 
data sheet for cachability limits.

CAUTION 

Use only an ATX12V compliant power supply with the D850MD and D850MV 
boards.  ATX12V power supplies have two power leads that provide required 
supplemental power for the Intel

 processor and the Intel

 850 

chipset.  Always connect the 20-pin and 4-pin leads of the ATX12V power supply 
to the corresponding connectors on the D850MD and D850MV boards.  
Otherwise, the board and the processor could be damaged.  

Do not use a standard ATX power supply.  Doing so could damage the board and 
the processor.
