Can DDR motherboards take SDR rams?

[MTAX]

Hi,

I'm having problems with 2 of my mbs. Thinking about replacing them. I have a gig of pc133 invested. Can the kt266/33 mbs use them?

Thanks.

Unfortunately, MTAX, none of the KT266A or KT333 chipset-based motherboards have any SDR memory slots at all. PC133 memory won't fit those DDR memory slots at all. And the only motherboards that still have SDR memory slots tend to use old chipsets (KT133/A, KT266 without the "A", ALi Magik-1) or are cheap bargain boards (ECS K7S5A, with SiS 735 chipset).

Thanks,

Do you know of a mb that takes 4x256 mb pc133?

Unfortunately, no currently available AMD-processor-based motherboards have four PC133 SDR memory slots. And even if one did, you wouldn't be able to get your system to run at all stable with all four memory sockets filled with modules running at 133 MHz - you'd have to back your memory speed down to 100 MHz.

Abit's KT333-based motherboards have four DDR memory slots - but if you use DDR333/PC2700 memory modules, you can only use a maximum of two double-sided modules OR one double-sided plus two single-sided modules OR four single-sided modules for stable operation.

And another thing, MTAX, for stability and compatibility reasons if you have 1GB of either PC133 or DDR memory, it's better to buy 2x512 MB of memory than 4x256 MB of memory.

Thanks for all your help cr4pz0r. I guess I have to find a kt133 mb.
