Memory Voltages

There is an issue I want to post for comments.

Did you see "hardware tecnicians" several times, when they try to put a new
memory module on some computer, they frequently only place that memory on
that "capable" motherboard ?. Then, if it "works", this is, if the computer
gets restart, then it is done,
your memory is correct for that computer.

I wonder if they always have to check the memory voltages first.

Perhaps it is easy to memorize such memory voltages, motherboard voltages
for memory modules. I have no experience on this issues
 
It makes no diffrence with a memory module,the "default" settings are the
same with either module.This being that the BIOS is operating correctly,only
a "custom BIOS setting" will change volts.

Nothing. Bring it up elsewhere"

Nothing for you,
my post has to do with any OS,
and any person who has interest
in hardware problems they could use with their OS
by the way, XP continues to be
one of the most used OS in the world

hence, I believe your attitude is extremely stupid,
an a complete lack of respect
to all readers of this forum.

Yes, ask in a hardware newsgroup. Since this *is* a hardware newsgroup a
better plan woud be to just ignore our resident ****wit.
 
My experience is that off-the-shelf mobos, e.g. Asus, MSI, Chaintech, etc
will cater for all standard module voltages and data timings.

That said, it is not always advisable to mix banks of different voltages or
timings. Some mobos will tolerate this, others will not.

The major problems arise with OEM-specifc mobos, which may not allow any
variance. HP/Compaq mobos are notorious for being incredibly finnicky about
the type of memory you fit. I suspect this is intentional, to force you to
but the OEM's own-brand RAM at inflationary prices. There is a way round
this, as some RAM manufacturers will supply special memory guaranteed to work
in these models.

-and no, there is no easy way to test the supply voltages, as board layouts
vary too much. If you can identify the RAM regulator transistor(s) you can
test there, but of course the voltage is only significant with the intended
RAM in place - the divider resistors are on the RAM itself. If testing this
way also beware that a probe slip (and resulting short) can cost you the
mobo, it's not a job for clumsy hands!
