is it safe to run a 64mb pc100 ram, with a 64mb pc133?
I found that very old PC100 memory, made when PC100 was the fastest
SDRAM, will almost always work at PC133 and CAS3, but newer PC100
memory won't, unless it's rated CAS2, but it has to be run at CAS3. I
would test the memory for 6-24 hours straight with MEMTEST86, starting
with the slowest PC133 BIOS timing settings and then with the normal
settings. Be sure to turn off any automatic settings, such as SPD.
And test with the case covered, to make the memory warmer. If you get
even one error, do not use that speed in normal use, and it would be
best for normal operation to be one notch below the fastest settings
that give completely reliable operation. But PC133 memory is
extremely cheap now, often $10-20 after rebate for 256M, and you may
be able to sell your PC100 memory at a premium to somebody with an
older computer that requires it.
Also if a power supply was blown, could it burn out a ram?
Yes, if its over/under voltage protection doesn't shut down the supply
in time (assuming it has such protection, but almost all do). But more
likely something on the motherboard caused caused the power supply to
put out more current or power than it could handle.
