pc100 vs pc133 voltage

Can anyone tell me if pc133 DIMMS consume more power then pc100's? I'm
wondering if that is the reason for my computer's instability...
(motherboard is AMD-756 Viper chipset, built for pc100...but if pc133 uses
more electricity, maybe that's what is locking the board? Like using the
motherboard's headers for fans...plus I/O)

 

Have a look at the capacitors on the board and see if they are swollen or
leaking. I had several boards that suffered this and created similar
symptoms. Good luck.

 

Look at spec sheets posted at www.micron.com

It's not, because memory modules consume so little power that they
never need heatsinks (Heatsinks on modules are only for decorative
purposes, as opposed to heatsinks on some video memory chips).

What brand memory chips do your modules have?

 

One has Samsung chips, and the other two have a logo which looks like "OC"
It's Kingston Value Ram...

Oddly enough, if I'm only running two modules, in any slots, the crash does
not occur. (I'm testing this now. It's been 30 hours, and all seems well)
If no crashes occur before Monday, I'll test this theory by re-adding a
third pc133 module.

Those "OC" chips are probably "B" quality chips or even used chips
that have had their original markings removed. Real part numbers are
a long series of digits and letters and will almost always return
Google search results, at least if you leave off enough characters
from the end.

Sometimes with a PC100 system it helps to run PC133 modules with
faster than normal timing. In other words if the PC133 module is
rated for CAS3, try it at CAS2 in a PC100 system. You'll have to turn
off the automatic configuration to make this work, sometimes labelled
"SPD" (Serial Presense Detect) instead of a number like 2, 2.5, or 3.
