CPU Voltage JP14
---------------------
3.3 (STD/VR) 2-3
3.5 (VRE) 1-2
Do I use STD(VR) or VRE voltage?
One of the most common questions is "Do I use STD (VR) or VRE settings
when I replace my CPU (processor)?".
For all Intel PentiumŪ CPUs - look at Pin Side (Underside) SXXXX / SMU
If the first letter after the '/' is an 'S' the voltage is
Standard (STD.or VR). (STD = 3.135v - 3.6v)
If the first letter after the '/' is a 'V' the voltage is
Voltage Regulator Enhanced (VRE). (VRE = 3.4v-3.6v)
For those who are interested the next letter (in this case the 'M')
indicates the timing (M for min valid MD timings and S for min valid
standard timings) and the last letter (the 'U' above) indicates whether
the processor can be used with multiprocessing motherboards
(i.e. more than one processor). If the letter is a 'U' then it has
been tested for single processing only - if it is a 'S' then it has
been tested for, single, dual and multi-processing.

P.S. M520 mainboard can use two types of Flash ROM __ 5 volt and 12 volt
Set the mainborad for either type with jumper JP4.
12 volt flash EEPROM ====> JP4 = closed
5 volt flash EEPROM =====> JP4 = open
( P.S. I suggest you to burn the new BIOS file into a new EPROM
or new Flash ROM and replace your current BIOS.(your old bios saved,
then if cannot use new bios use the old bios chip again. Because many
people make mistakes when update BIOS... the system cannot work again.))
