I'm going the Athlon route (hopefully dual) myself soon, and want to get PC2100 ECC memory with it, so I'm glad to know you've made it work. My above comment was just a repetition of something that I'd read on one of the hardware review sites; hopefully, I made it sufficiently clear that I could have been wrong, as it turned out I was. Incidentally, what I really meant by my comment was that I had read that certain chipsets that support Athlons due not play well with ECC. I wonder if this is still possibly true, and your Asus is just an example of a better motherboard which uses a more-competently engineered chipset. Let's see... What are the main chipsets that support Athlon? AMD 760, Via kt133, Ali Magick (?or something), Sis (something I think). Anyone know if there is anything behind what I remember reading with one of these chipsets? Or maybe I'm just completely mistaken... Anyway, take care and thanks for sharing your Athlon success with me. -Daniel -- Daniel A. Freedman Laboratory for Atomic and Solid State Physics Department of Physics Cornell University

That seems rather unlikely, since ECC is handled entirely in hardware in the memory subsystem. -- John Hasler [EMAIL PROTECTED] (John Hasler) Dancing Horse Hill Elmwood, WI

So normal SDRAM is for example 32Mx64 (for 256Mb module), while ECC SDRAM is 32Mx72 (for same 256Mb with ECC capabilities). In many cases you can get ECC capabilities for maybe $8-10 more for a 256Mb module, in which case I think it's a good investment. Note, though, that I've heard Athlon doesn't play well with ECC, though it remains to be seen if this will be improved for the Dual Athlons (as it should be); again, hopefully, others can add more.
