hey all,
I have an issue with some memory that has me stumped.
Due to an upgrade, I had 4x1GB sticks of RAM spare, so I figured I'd put
these into another machine of mine that currently only has 1 GB total.
(It's a little ITX board for media playback)
However, after putting the new RAM in, the machine won't boot Ubuntu
reliably, and memtest+ on the Ubuntu install disc shows up lots of
memory errors. The memory was also *extremely* hot when I removed it
from the machine. I tried the memory in pairs of two matched sticks at a
time.
Returning the memory to original machine, it runs memtest+ with no errors.
Is there some kind of memory incompatibility that I'm unaware of going
on here?
The specs:
Machine A, working combination:
Motherboard: Intel P35 chipset
RAM: 4x 1GB of DDR2-800
Machine B, working combination:
Motherboard: Zotac nForce 630i
RAM: 2x 512MB of DDR2-667
The latter motherboard says it supports DDR2-800 memory.
I moved the CPU over from machine A to B, but that didn't help.
I was especially bothered by the RAM getting very hot - I'm pretty sure
that's not normal - although that machine is in a very small case
without brilliant ventilation. But it was hot after just a few minutes
of run time.
I wondered if you had any thoughts?
Thanks,
Toby

I had a memory issue with memory above 512Mb. The errors only occured
after days of running (causing root to be remounted read only due to
errors) and memtest++ only found problems under test6 I think. I
clocked down the memory speeds in the BIOS and it was fine and just
ran it with the slower clocking.

Perhaps it's related to your mother board and large amounts of memory.
Many motherboards may claim to support a certain speed but not work
reliably with more than 1-2 sticks at that speed.

Hi Toby.
Could you have the motherboard RAM voltages running too
high for the 1Gb RAM to handle?
Compare the BIOS RAM voltage settings for the two boards
and ensure that the Zotac board is not running higher
voltages.
Is the RAM one of the brands and part numbers shown as supported
in the motherboard documentation?
Regards,
Morrie.

The ITX board I'm using didn't have any options to over-voltage the RAM
manually, I think. (I wondered about this too)
I really hope it wasn't trying to do so automatically :/
Compare the BIOS RAM voltage settings for the two
boards
and ensure that the Zotac board is not running higher
voltages.
I'll have to see if that voltage is reported anywhere; I know it is on
the Asus board, but don't recall it on the Zotac nForce one.
Is the RAM one of the brands and part numbers shown as
supported
in the motherboard documentation?
A-ha-ha.. I threw out the motherboard documentation years ago :/
Good points though.
Cheers!

all you need for a search is the brand and the model.

Mind you, ark.intel.com tells me that the ICH8 chipsets in my laptops can
take a maximum of 4GB of ram, but they both have 6GB in them according to
/usr/bin/free. Magic, I guess.

I've seen other info on ark.intel.com that is just plain wrong,
so I wouldn't go trusting it..

We got caught out just recently when we went to put 'registered' memory
in a server that wanted 'unbuffered' memory. It fit perfectly but just
didn't work.
