There are two kinds AMD K6 300MHz CPUs - one has 3.3V I/O and the other has 3.45V I/O. We only support 3.3V.

**

These CPUs will operate only in single CPU configurations.  166-266MHz AMD CPU and S1592S certified by AMD

***

Due to AMD K6-2+ and K6-3+ CPUs being mobile CPU solutions, they are not supported on the boards as indicated.

#

Numbers corresponding to Cyrix 6x86 (M1) are Cyrix performance reading numbers -
NOT an indication of true frequency.

##

S1590 revision 4 or above and S1598 boards support AMD K6-2 500 or 550 MHz CPU's with proper heat sink and cooling. To determine your board revision, see image.
