AMD K62-400

[Zab]

What is the standard voltage of this chip?

 

[Hyper99]

2.2V
Wanna overclock?
Try 2.6V
and 450mhz

Thanks.
I only have a 5.5 x 66 Mhz so its 366 tops.

Set it to 2X, the cpu will remap it to 6X and give you 400.

You sure all you have is 66 MHz? If your board supports the K6-2, you may have 75 or 83 at your disposal as well...

And yes, DaddyG is correct...2X multiplier on a K6-2 is interpreted by the CPU as a 6X.

Also, I don't know that all K6-2 400s have a 2.2V core by default. My 450, for instance, had a 2.4V core. I ran it at 2.9V to get 504. They don't seem to object to much to high voltage, if you have proper cooling on them.

Good luck.

AMD Tech Manual gives 2.1 to 2.3V nominal range for both AFQ and AFR versions of the 400.

If you are interested in more info on K6, here are some good articles:

Older article but principles are the same.

There are several articles in the list.

Thanks for all the useful info. The board is a gigabyte GA-586TX3 if that helps.

I don't have the exact refernce in front of me, but there are 2 different version, 1 runs at 2.4, the other 2.2.
2.4 should be marked as AHX-400
2.2 should be marked as AFX-400
This is assuming that my memory is right on this- it should also have the voltage on the chip

DDaD,

I know that the K6-3 400 comes as AHX, but I can't find info on K6-2 AHX.
Any idea where you saw it?

Thanks.

My K6-2 450 is an AHX.

Would be nice if they remapped 2.5 to 6.5
and 3.0 to 7.0 and 1.5 to 7.5
That would give a total of 500mhz on an old pentium board...
But then again 400mhz is better then running it at 366 or 233mhz

Viper GTS,

Yes, the manual shows K6-2 450 marked as either AHX or AFX.
