Memory Support on P2/P3 based machines

I've recently managed to get 2x128mb sticks of SD Ram cheaply, however they
dont work to their full potential in my P2L-M, as when I got them I realised
they were single sided DIMMs with only 4 chips (as I've been told before on
this board, they only show up as half on this mobo).

My question is basically what sorts of P2/P3 based motherboards (sckt 370 or
slot 1, don't mind) support this memory? Is my P2L-M wierd in the way it
doesn't work properly with this memory, or do most mobos from this era have
troubles?

Thanks

Any board with a chipset supporting 256 MBit or larger ICs should
swallow these. i815, VIA Apollo Pro 133A/T, SiS 635 and such.

The almost 7 year old i440LX (like the i440BX and other chipsets of
similar vintage) was only designed to support 16 and 64 MBit ICs,
certain 128 MBit ICs are (inofficially) supported more because of lucky
circumstances. 256 MBit ICs not only cannot be fully addressed, they'd
also need faster refresh to function properly.
