Here is the issue. I have an A7V266-C motherboard that is giving some RAM
issues. With 512MB PC2100 installed, it runs like a top, no hiccups at all.
When I add another stick of 512 to the mix, same PC2100, blue screen, shut
down, die in a horrible manner. This is the second stick of 512MB RAM I
have tried now, with the same issue. All the RAM is of the same mnfctr, and
all tests are fine. I am at a loss.
I explored the website for ASUS, thinking that it could not handle a stick
of 512 PC2100, but no references are made. it says max 3GB PC1600/2100.
Some boards I have come across will only handle more than 256 per slot if
it is PC1600.
At a loss, any ideas would be great.
 
What operating system are you using?

Win98 was suppose to have a limit of 384 Meg of RAM. You can usually run it
up to 512 Meg. This is a problem caused by windows.

Asus motherboards have some finicky preferences to certain organizations of
RAM chips on the individual SDRAM DIMM. I usually go to the website at
www.crucial.com and write down the part numbers of the memory they recommend
for the motherboard and then purchase that part number from another location
like www.newegg.com if I can get a better deal.

So far this has worked out for me.

No, not true. Windows 98's RAM limit is either 1GB or 2GB,
depending on which of two contradictory Microsoft Knowledge Base
article you believe. Since I know people who run it with over
1GB, I choose to believe the 2GB number.

Many (but not all) Windows 98 systems with more than 512MB need a
statement in system.ini limiting the size of the vcache to 512MB,
but that's very diferent from a 512MB limit on installed RAM.

Many boards are less stable when using multiple, double-sided memory.
Try manually setting slower settings in the BIOS (higher numbers). It
"might" help to fill the first and last slots, leaving the middle
empty (it has 3 memory slots, right?).

Hmm, so what works is:

(a) The 512MB DIMM on its own
(b) The two 256MB DIMMs together

?

But adding that second 512MB DIMM fails? Odd. And both 512MB DIMM and
256MB DIMM are both double-sided? Isn't this dual-channel, which I thought
means you have to have two DIMMs installed to work? Which fails on the
512MB one, but the 256MB works?

I checked online and found this link:

http://www.aberdeeninc.com/abcatg/MB7710.htm

Which lists your board as supporting all sizes of DIMMs, 128 to 1024MB. One
other thing, are the specs the same on the 256MB and 512MB modules? I refer
to pin count (184?), CL number, etc.? Just wondered.

I had a look at the online manual for your motherboard, it has interesting
information in it regarding the DIMMs. Have a look at section 3.5, page 23.
The link to the Asus download link for your manual follows.

DDR RAM, and it won't even POST, so OS is a mute point.

It's a 'moot point' not 'mute point'! ;o) Changes the meaning of the
sentence somewhat! >;o)
