DDR? What? huh?

I have an Epox EP-8KTA2, which does not support DDR. My motherboard manual says I can put in as much as a 1.4 T-Bird, but I have yet to find one procesor over 1.1 ghz that is not DDR. I would really like to drop in something like a 1.2 duron, or some T-Bird, but my motherboard does not do ddr. Is there a processor over 1 ghz that i can put in my machine?

is the 8KTA2 a KT133A chipset? the CPU BUS has always been DDR FYI... even since the KX133 days with the Classic Athlons...
so if your mobo is a KT133A, it will support a 266FSB (DDR), the only thing is, the memory is SDR.

Ok, first thing, processors are not DDR, ram can be DDR, but your board takes SDram. The processors that are on boards are either 200 or 266Mhz fsb boards(which is 100 or 133 x 2). I checked out the specs on the EP-8KTA2, and unfortunately Epox doesn't recommend anything larger than a 1100Mhz according to a pdf link to the mobo specs. If you want the fastest cpu your board can take, look for the 1100Mhz Athlon with 200Mhz fsb for the Athlon, or the "classic" Duron up to 950Mhz with 200Mhz fsb, not the newer Morgan core.

Processor and RAM DDR have nothing to do with each other.

All AMD K7 class processors (Athlons and Durons) have always been operating on a DDR Data bus. This is completely separate and independent of the RAM. What chipset your motherboard is based on will determine whether or not you can use DDR RAM. In just about all motherboards (except those based on the ALi Magik1 and SiS 735 chipsets), you will use one type of RAM or the other, but not both.

OK sure... what do you think 200 FSB is then? it's 100x2... hence DDR... what he doesn't know is, just because his mobo is SDRAM, doesn't mean he can't have a DDR CPU in there.. well, he does already, but a 266 CPU in there I think is what he is asking.. any Athlon classic/Duron/T-Bird runs on a DDR BUS, some are 133x2, and some are 100x2. but the VIA KT133A is the best chipset to support 266FSB in SDRAM form..

Ok, yes, cpus can be thought of as DDR, but I'm not accustomed to talking about them like that. I would just think of it as dual piped or dual pumped :) Since the Athlons have been around, they have been this way.

Maybe I worded it a bit weird, but if you look above, I did say 100 x 2 and 133 x 2 to give 200/266. But anyway, his chipset is the KT133, not the KT133a which is found on the EP-8kta3.

Yeah, that's what I didn't know, the KT133 will only take a 200FSB Athlon/Duron, I think they make them all the way upto 1.4, but those are HARD to find..
if it was the 8KTA3Pro, it would have full support for 266 FSB and maybe even AXP's.

AMD's above 1.1ghz that use a 100mhz (200mhz effective) FSB are difficult to find, What do you have on the board at the moment or s this a new build?

If you have a 1ghz Athlon then you won't see an enourmous performence boost going to a 1.2ghz Duron but if you have something like a 800mhz or if it's a new build then the Morgan based Duron 1.2ghz wouldn't be a bad choice.

Not sure what cpu he has already, but here are the Epox Cpu specs for the 8kta2 as well as other Epox mobos.
