New system: Why does the system show only 128MB of memory from a single 256MB DDR(266) stick? Gigabyte MB, AMI BIOS, WIN98SE OS, AMD 1.6MHz CPU. Dip switches on MB are set right as per the MB manual, BIOS appears to be set right. Any suggestions?

I assume the motherboard excepts over 128 megs per bank. Try swapping out the RAM for another 256 your chip just maybe bad above 128 and is default down to what does work.

Boy, this sure sounds like the old DIMM incompatabillity issue all over again.

I was hoping that DDR was not going to have any problems.

Is this a 200MHz or 266MHz FSB motherboard?

Check with Gigabyte for a BIOS update. This may be a problem that was found post production.

Also, make sure that the DDR is in slot 0/1.

Inspect both the DDR and the socket under magnification for bad pins.

Hi,

Oh and if it doesn't specifically say on it... check that you indeed have a 256Mb stick! Someone may have given you the wrong one by mistake....

Cheers,
Tim.
