Can someone list all the KT333 boards with the 1/5th divider?

I know some of you have this list memorized.I ordered an xp1600 & would rather kick up the bus than unlock the cpu.

Do any of the 266A boards have the 1/5th divider?

Can someone explain to me how a KT333 could NOT have a 1/5th divider? I mean if you are going to run the FSB at 166 natively and keep PCI within spec you would have to have a 1/5th divider, right? So how could anyone make one without it?

Well I just know the Epox, the KT333 is for sure that has 1/5th divider. Im not sure about the KT266A Epox mobo.
Snatchface I think you will need the 1/5th divider only if you run @ 166 mhz FSB synchronously(1:1), most KT333 mobos work assynchronously(4:3, 4:5, etc).

What do ou mean Rafael, that they run memory at 166 and the fsb stays at 133? That kinda defeats the whole purpose of stating that this chipset supports a 166 FSB, dont you think?

Oops...my bad. Guess i'm a bit outdated...just read this off of the review here

The most limiting factor here will be the Athlon's 133MHz DDR FSB which will only allow a maximum of 2.1GB/s of data to travel to/from the CPU. So in spite of the fact that the chipset will be able to get, in theory, up to 2.7GB/s of data from main memory it will only be able to hand 2.1GB/s off to the CPU.

I guess that's why everyone has their collective panties in a bunch over the new 166 XP's. Nevermind.

Let me give you one example that the Gigabyte GA-7VRXP doesn't have the 1/5th divider.

It's something like this Snatch. I dont know how exactly it works. But its similar to the old TBs and mobos(KT133, KT133A, etc) that you set the FSB @ 100 Mhz, and the memos to work @ 133 Mhz.
I agree with you that it kinda defeats the purpose of the chipset. It only works assynchronously @ 166 Mhz, since the processors are only 133 Mhz FSB. I think the KT400 will work synchronously as ur wish!
But I think you got the main idea.

Come on,I know someone knows these

Buy the 8K5A2, 8K5A3, or KX7-333, these seem to be the best overclockers and all have the 1/5 divider. BTW if you are using 2700DDR and it won't handle being run @200mhz then just pick manual memory settings in the bios and set it to 133mhz(2100DDR instead of 2700) and when you set the FSB to 166mhz the DDR will be perfectly in spec as well as the AGP/PCI
