I put DDR RAM module into my socket, and when I turned the computer
on, 2 of the contacts got burnt. I think it's 184 pin RAM and it's
pin/contacts 86 and 78. That is the 8th and 16th contact counting
from the 93rd contact towards the first. Interestingly, on a diff
make/model of mobo, diff make ram , diff PSU, I had the same problem.
the exact 2 same contacts got burnt.
The events before, were, i restarted the comp (via windows) and it
reset but wasn't starting. I took a (the only) RAM module out. put it
the other socket, and it was fine.
THen i restarted through windows, and it reset but wouldn't start. I
unplugged te power. took the RAM out of the socket put it back in hte
same socket. turned on the power. switched it on, and hey presto, i
smelt burning and saw my ram module had burnt out.
anybody got any ideas what the problem is, how to diagnose?
I know i'm going to h ave to take the mobo back. But, this has happened
once before and ideally i really want to be able to detect a problem
like this before it hits and takes out my RAM too. I want to at least
detect what caused the problem.
It may be of interest, I tested the Voltages coming out the ram
sockets with a multimeter (could i have electricuted myself from
that? e.g. if a current surge caused the problem)
On a working board of the same kind , I got voltages of 2.6v and 1.3v,
depending on which contact i touched.
On the now screwed up board with the no doubt partially burnt socket I
got voltages of 0vv often and sometimes 0.3v . So not suprisingly,
the mobo seems buggered, but this is of course after the event.
I spoke to a guru electrician, he said maybe i could check a capacitor
with a 'good LCR meter'. And he said a multimeter won't pick up a PSU
swurge because it's all in the switching, and it's so fast the
multimeter wouldn't pick it up. he said i'd need an oscilloscope.
Well, i'm not electronics guru.
But you are RAM gurus
I'm thinking maybe you chip, MOBO and RAM specialists gurus and experts
have some idea of what happened, it was *the exact same 2 contacts *
that got burnt as on a diff comp i once had! So this must be a standard
prob. And that last time they burnt when I tried to turn it on. So,
v. similar to this time round.
