K6 VS K6-2
 

I have an AMptron 8400c MOBO with a 233mmx procesor that I would like to upgrade. The manual says that a K6 300mhz will work. What is the difference in K6 and K6-2 processors. This Mobo has a 83mhz FSB speed max. will the K6-2 work on this MOBO?

Looks like your mobo only goes down to 2.5 v for the CPU...I elive the K6 - 2 require 2.2V. Doesn't look like it will work :(

That MB will have a hard time with a K6-2 due to the lowest voltage provided is 2.5v. It might drain too much power, but if it works a K6-2 would perform better. You might have to run some some tools to optimize the K6-2 on your older MB, but those are relatively painless.

If anyone has a K6 300 CPU lying about I would be intrested in it.Drop me an E-mail

I think some K6-2's might run 2.4VCore. Trey K6plus.50megs.com for K6 help.

That's an odd combination. As far as I remember, all K6's and K6-2's ran at 2.2 volts. If your mobo doesn't drop below 2.5 volts that would invalidate the statement.

Your mobo may have unmarked voltage connections for lower voltages. CHeck it out. Also, with an 83 MHz FSB you could theoretically run up to a K6-2 500 if your mobo supports a 2x multiplier (setting the multiplier to 2x for a K6-2 500 would equal a 6x multiplier thanks to an internal chip re-map). 6x83=498.

the main difference between the k6 and k62 is the addition of 3dnow instructions, I THINK a smaller die, and 100mhz fsb!!

I ran a 300 at 4x100fsb for almost a year, had the voltage at 2.6v.. had a alpha cooler on it to keep it cool.

If you are carefull, it might work for you too.. get a BIG heatsink/fan....

the chips are pretty cheap now...:cool:

Well I'm just out of luck with the K6-2 thing. My board only goes down to 2.5 volts with 1.5/3.5x multiplier. so back to looking for the 300 K6, any more suggestions? Maybe I should just overclock it, I have never done it, and truthfuly a little afraid of it.

K6/2 voltage
 

I've run a K6/2 2.2v @ 2.5 Volts no problem. If you can do a bus speed and multiplier that the chip will do, then go for it.

Just make sure you have a good heatsink, paste, and decent case ventilation.

www.compugeeks.com has used K6/2 300s for $14, so it's not like you're gonna be out much if it fails.

Good luck

The original K6-2s run at 2.4 volts but if you try to use one in this board at 2.5 volts, with a massive heat sink, it will draw way too much current.

It will probably work for a short period of time and then toast the on board regulator.
