DDR RAM Slots

[Facin]

My motherboard seems to have died on my computer at home. It has regular PC133 SDRAM, and with the prices of memory rising, I was kinda hoping not to have to purchase new memory at this time. Anyway, I would like to purchase one of the DDR motherboards (KT266A) that would allow me to upgrade to DDR in the near future, but from what I understand, the DDR slots will not take regular old SDRAM different pins). Well, a buddy at work is swearing that this can be done and that he has done it...I just don't know if I believe him. Can the DDR motherboards support old PC133 SDRAM or not? Otherwise, I will just purchase a KT133A motherboard and go on with life.

Thanks

It is impossible to use SDR SDRAM in a DDR SDRAM slot since the pincount is different. DDR has 184 pins while SDR has 168 pins. Some boards like the ECS K7S5A based on the SIS735 does have both 168 pin SDR and 184 pin DDR SIMM slots available. perhaps he has a board that can handle both types of memory. Be aware that you can use one or the other but not both types of memory at the same time.

Thanks. That's what I had suspected. I don't think my buddy has one of those dual mthbds, but I think he has a something like a KT133A and thinks he has a DDR board because the salesman at compusa said it was or something.

Anyway, thanks.

Yes, I would think about the ECS mobo as well. It's a great deal and it can take both type of memory(although like Windogg said, not at the same time). You could always sell the mobo and pc133 ram in the future and get a new mobo and ram.
