PC crashing after installing additional RAM

I had exactly the same problem. I have two 1 gig RAM modules and they
work fine. When I had 2 more 1 Gig RAM modules the system starts to
crash and often won't even boot up properly. I think the module(s)
are defective, at least that is what a repair technician thinks. I
still have those modules, they are made by Corsair. Someone said they
have a lifetime warranty and that I could return them to the mfr, but
I have not pursued that yet.

They also fail to boot when I remove the original modules and install
the Corsair ones in their place.

Don't know if it has anything to do with it but i would guess
that the timings of the memory you got are not the same as the one
you had.

Recently, i bought 2 more 1 GB Corsair memory modules for my PC,
like the ones i had, with the exception of the timings: the original
were CL5 and the newer ones were CL4. Everything worked fine, for a
while (a few days), and then i started having crash after crash
after crash. I thought i had a problem with windows so i tried to
repair it but it started to crash there as well. That got me pissed,
so i formated the drive. Started a fresh install and it was going OK
until ... just after it had finished installing, it started crashing
again so i thought it might have something to do with my hardware.
After LOTS of wasted time trying to find the hardware problem i
tried to do a fresh install with the original memory only and it
worked fine. Tried putting the memory in the other 2 slots to see if
the problem was with the board and that too worked fine and that
meant i could, finally, reach a conclusion: the newer memory was
faulty ... until, just to double check, i tried the newer memory
instead of the old one and ... it worked too. WTF???? Tried changing
the slots of the newer memory and it worked as well.

Long story short, as far as i can tell, all 4 DIMMs work well:
just not all 4 the same time. It could be you have a similar
problem: have you checked to be sure that all your memory have the
same timings?

Hope this can help shed some light into the problem, HTC

A 4 module configuration is far les forgiving than a two module
configuration. This can lead to the described configuration.

That is a sign that the modules are either defect or incompatible
with the mainboard. re they loisted in the certified memory
modules list for that board? The problem is, that if they are
incompatible, no number of warranty replacements will
fix the problem.

You may be interested in this reply posted by Colin Barnhorst in Microsoft's
x64 newsgroup:

-------------------------------------------------------------------------------------------
It depends on your mobo. There are a lot of reports of problems running
four dimms of pc6400 ram, whether 4x1GB or 4x2GB on consumer mobos. It
isn't so much the amount of ram as the number of dimm slots filled.

A common resolution is not to use pc6400 or reduce the dram speed to 667.
Mobos with nVidia chipsets are mentioned most often. Nforce4, 650i, and
680i are ones I know about. The problem seems to be a combination of
factors that overload the memory controller at 800 with all four dimm slots
filled. You don't give any specifics of your hardware so that's about all I
can tell you. By the way, the problem isn't confined to Vista x64. It also
exists with XP Pro x64.
------------------------------------------------------------------------------------------

For what it's worth, I've had no problems with 4GB on either of my two Asus
intel chipset mobos. But the issue certainly exists, and this could be a
resolution. The suggested reduction of speed to 667 does not make a big
difference - and may enable you to use some judicious overclocking with RAM
that would otherwise not be co-operative.

Not necessarily! I've posted previously about a problem I encountered
when going
from 2GB to 4GB of RAM on my Asus M2A-VM HDMI. Even though the sticks
were from different manufacturers, it wasn't a hardware issue at all.
An upgrade
to BIOS version 1501 solved the problem.
I believe that there would be general agreement in this group that a
BIOS upgrade
should be one of the first steps one should take when these kind of
issues arise.
At least you know that you're dealing with the "latest and greatest".
If problems
persist then it's probably caused by the power supply...
