PC133 RAM on ASUS P2B-S?

[JustMike]

I have an oldie-but-a-goodie ASUS P2B-S (Intel BX-based) motherboard in a server and would like to upgrade the RAM probably to the maximum of 1GB. I understand that this board originally called for PC100, but I don't know if this was single sided or double sided. If I have the right type of PC133, can I use it on this board?

pc133 will work on that board. I've used it on both my p2b & p3b-f boards.
the largest dimm size that you can use is 256Mb on that board.
suggest you go to crucial, use the memory configurator & you'll be guaranteed to get the correct ram.

Do I have to worry about single/double-sided? I am trying to scrounge some ram up and don't want to pay Crucial's prices.

the 256MB dimms *must* be double-sided, two-bank dimms based on 16kx8m sdrams.
If you want to reach a full 1 gigabyte configuration, suggest you use only pc133 cl2
sdrams from a reputable source.

Perfect! Exactly the info I needed. Thanks.

Actually, for really stable operation of four double sided DIMMs on an Intel BX chipset, registered DIMMs should be used. (And then 440BX can even use 512-MByte DIMMs!)

Using standard (unbuffered) DIMMs, DIMMs must be no larger than 128 MBytes per side (as has been said above), and you should refrain from putting four of those in. That's asking for trouble, somewhat.

1GB limit for the good ol' 440BX.

Thanks again... I think 2 x 256MB would make me happy for the time being. I don't want to pay top dollar for registered RAM for this old board. It's only got a PII 350 on it.

I don't have the P2B-S but have P3B-F and I like it old or not and it is upgradable to a point,
will accept the pc133 but at the lower frequency.
