CPU Upgrade/ VRM Header 

 

In  case  that  you  would  like  to  upgrade  your  CPU,  make  sure 
that  you  have  followed  the  hardware  setting  described  in 
Appendix-C  for new CPU setting. If you upgrade your Pentium 
with CPU such as P55C , care must be taken to install the VRM 
used in connection with the CPU. 
 
VRM  stands  for  Voltage  Regulator  Module  and  is  specially 
designed  to  provide  a  steady  power  source  (with  voltage  of 
around  2.5V)    for  use  by  P55C  CPU.  CPU  such  as  P54C, 
P54CT, P54CS, P54CQS do not need to use the VRM as all the 
voltage  required  (about  3.3.V)  has  already  provided  by  the 
mainboard.  
 
Inside  RHINO  5  motherboard,  you  will  find  the  VRM  header 
(Header 7) which is stuffed with four jumper shunts. To install 
the VRM , remove the four jumper shunts and insert the VRM 
into  the  header.  Make  sure  that  it  is  securely  stuffed  by  the 
header. 

 
 
 

 
 

 

 
Never change the jumper shunts  in the VRM 
header  if  you  are  not  upgrading  the  P55C  
CPU.
