new single sided ram in old mobo?

[mcveigh]

I just put a new stick of 128MB of pc133 sdram into an older intel al440lx motherboard. it only shows up as 64 MB is this cause it's single sided?

the specs on the motherboard say it can take up to 256MB per slot so shouldn't be able to detect the full 128MB?

Old boards are very picky about large sticks of RAM. Some will work, some won't. The 128's were not common in the 440LX days, so compatibility would be iffy. You could try a 128 double sided... it may work better, but it's still not guaranteed to work.

The only 128 I ever ran on an LX was a registered DIMM.

I had a look at your boards specs, and it says that it can take a single sided 128.

The LX chipset does not support high density RAM. You can normally identify this type of RAM by how many chips is has. If there are chips on both sides of the memory module its high density. If they are on a single side its normal.

I had a similar problem on a 440LX board just 2 weeks ago. Bought 2 64MB high density DIMMs, chips on both sides. Both modules are detected as 32MB :/ Exchanged them for 2 64MB single sided modules and they are correctly detected now.

modules are only on one side
