What are the clock multipliers(1.5x,2x,...) supported by K6-2 266,300,333,350? I know that the K6-2 300 support 3x100, 4.5x66 and maybe 3.5x,4x ...
What are the I/O voltages of K6-2 333,350? I know that K6-2 266, 300 have 3.3I/O and that K6(-1) 300 3.45I/O ...

doesn't this put this question in the "it has to answer itself" catagory

as far as i know, they don't have to 'support' any particular multiplier speed. i think they run at a bus speed of 66 or 83 or 100 depending on your ram and motherboard, and after that it's just the clock multiplier which brings it up to speed. of course a faster bus speed is more desiarable than a higher clock multiplier. there is probably a limit on bus speed of 100 mhz.

with regards to the voltages, go to http://www.amd.com/K6/k6docs/ and you might find stuff there which u like..

Hey guys, I didn't have a much more points................I can't buy points so................how much points do you think I musted give for that question? I don't understand that 'poins-wanting' :). These expert points that are becomed when answered a qusetion are useless :) Why anyone want more and more? When I answer some question I don't care for the points ....
------------------------------------------------------------------------------------
Let's say the 'voltage qst.' with other words: why is the core of K6(-1) 233 3.2V instead of 2.9 and why is the I/O of K6(-1) 300 3.45V instead of 3.3?

hehe.. firstly, i'm not squibbling about points. just that usually people give more points. i guess cos collecting points makes one look better. more points = more respected expert :)

with regards to voltage, 3.45 displayed on the bios is not really 3.45, it's just a rough guide. motherboards do not give out voltage as accurately as you think and there can actually be quite a great fluctuation! sometimes people increase voltage when they overclock, but thats not in question bound.

as to how come they require different voltages, it's probably just because of the way that the chip is designed. if you really wanted the answer, just write to the technical support at amd, they're quite nice people and will gladly answer your question much better than the people here can (unless they work at amd :))

OK you ready here it is
k6 233-233Mhz(66x3.5)- 3.2v/3.3v split
k6 233-233mhz(66x3.5)- 3.3v/3.3v split
k6 233-233MHz(66x3.5)- 2.2v/3.3v split
k6 266-266Mhz(66x4.0)- 2,2v/3.3v split
K6 300-300Mhz(66x4.5)- 2.2v/3.45v split
K6-2 266-266Mhz(66x4.0) or 250Mhz(100X2.5)- 2.2v/3.3v split
k6-2 300-300Mhz(100x3.0)- 2.2v/3.3v split
K6-2 333-333Mhz(95x3.5)- 2.2v/3.3v split
k6-2 350-350Mhz(100x3.5)- 2.2v/3.3v split
some Mhz cpu's have more than One version like k6 233
some cpu's perform differently on different mainboards (k6-2 266)
also I can't remember but the k6-2 300 might have a 66mhz board
setting but I couldn't find it.

Buy the way this was bugging me so I went and got my folder from
work. HOPE THAT P_SSES jimat OFF!

gward, as I understand the K6-2 333 and 350 can be run ONLY at 3.5x - I have a board with 83MHz bus and can I run the K6-2 333 to 4x83 or 5x66?
the voltages are OK.
I am not asking for the "official" multipliers supported....I need to know the multipliers(ALL) that the chips(266/300/333/350) will accept to find out what is the best solution for my board.

If know about voltage settings on Shuttle 569 check my question from 9/12/98 and tell me how to set a MMX233 CPU with 2.9core/3.45 I/O... or K6-2/333 with 2.2core/3.45I/O

Ok as I see it you know how to set the core but you have no setting for the 3.45I/O or don't know what it is .But there is a small prob ,most mainboards are behind in this catagory .But most are sending out updates.And others would like you to purcase new board.(BS huh)THis is what I can do check updates
I can't promise anything but if find it your welcome to it.

Yes the chipset is TX.
Thanks for the Shuttle-number, but I am very far far away from USA.............
Help with the I/O 3.45 settings if you can - else don't worry........

The question about multipliers can be sayed so:
Work the K6-2/333 with 5x66?
Work the K6-2/350 with 5.5x66?
Support the K6-2/266  all 1.5x-4x ?
Support the K6-2/300  all 1.5x-4.5x ?
Support the K6-2/333  all 1.5x-5x ?
Support the K6-2/350  all 1.5x-5.5x ?

The I/O voltage is not critical, and on most MBs not adjustable. For example ATX supplies output nominal 3.3 V that powerws all of the logic. In other words you only need to worry about the core.
