I'm playing around with an old Asus K7M (Athlon) motherboard (with a
Athlon processor on it)....
I have various memory modules... and I've found the K7M will run modules
boards won't (i.e. registered ECC modules).
I have 128, 256, 512, and 1G registered ECC modules....
All work... but the 512 and 1G modules only see half of each stick...
unsure if it is
seeing the 1st half of each chip, or only half the chips.
This board was only rated at 768M (3 x 256M DIMMs) from ASUS.
using 3 1G DIMMs, the system sees 1.5G of memory... pushing the platform
what Asus intended....
Now, the 256 and 512M modules are both double sided using 18 memory
chips. The 1G
DIMMs are double sided using 18 or 36 memory chips.
I'm wondering if there are some different density modules that would
allow me to
run 3 x 512M DIMMs and see them as 3 x 512M DIMMS... vs wasting half of
to inaccessibility ?
Any ideas if there were 'low density' 512M PC133 DIMMs as well as 'high
Too bad there wasn't a way to get the K7M to see all 3G of RAM >:)
