Voltage regulator module for Vectra XM5 series 4

[Guest]

Archived from groups: comp.sys.hp.hardware (More info?)

Hello,

I can upgrade my router's hardware with a faster CPU (a non-MMX Pentium
with 166 MHz) more suitable for encrypted networking. This specific CPU is
mentioned in the tech manual for the Vectra XM5 series 4 system board and
certified (P54C).

However, I need a VRM as there is none installed currently. The HP part
number would be 5063-7940. I have a VRM for a Pentium II (Kayak XU6/333)
floating around.

Will that VRM work as well? Do VRMs for Pentium II and Pentium P54C differ
significantly?

Thanks.

VRM's for Socket 7 versus Pentium Pro, Pentium II or Pentium III are quite
different. You CAN use a non-HP VRM, provided its installation has enough
clearance with the power supply above it on most HP Socket 7 Vectras.

If you can't find a suitable VRM, consider upgrading to a 200MHz Classic Pentium
or a 200MHz Pentium OverDrive. The latter has MMX instructions, but operates at
the same voltage as a classic Pentium.

I doubt that router software would ever do much to use MMX instructions, but the
additional speed would be nice.

I've had a lot of trouble upgrading CPUs in Socket 7 Vectras in the past,
because the power supply leaves little vertical clearance for the VRM.

Thank you, Ben. So that means that I can use a non-HP VRM, but I can't use
one for a Pentium II, III or Pro?

Correct. A PPro, P2 or P3 VRM will not fit into the VRM socket of the Vectra
XM5 Series 4. But all VRMs of a certain type meet the Intel specification, so a
non-HP VRM will work properly... Ben Myers
