AMD Athlon K6-3+ 400 ATZ WPAW CPU works at 550Mhz 2.2V
This CPU is anAMD Athlon K6-3 400+ ATZ WPAWCPU and ist new old stock (never used).
I tested some of these CPUs (I have several) on a Super Socket 7 mainboard (Epox EP-MVP3G5) and it is running fine at 550 Mhz in my tests.
Check your board to make sure it will support the low 1.6V voltage of this CPU, or use a higher voltage with higher clocks like 500Mhz or 550Mhz.
This makes it oneof the fasted available CPUs for Super Socket 7 mainboards. This K6-III+ is one of the most efficient Socket 7 CPUs and has it´s own L2 Cache. The mainboard cache will be used as L3 cache which allows not only high performance but a maximum memory footprint. In other words: You can install as much memory as you want without performance degradation observed otherwise, e.g. with a K6-2 CPU.
This AMD K6-3+ CPU which is even better than normal K6-3 CPUs.
While the CPU is listed as "embedded" it works with all mainboards which will work with the regular K6-3 CPUs
Same features, lower energy and voltage requirement.
It has a TDP of only 9.5 watts and will work with passive cooling.
At least with it´s stock 400 Mhz clock. If you set higher clocks like 550Mhz you will need cooling of course.
Under the picture you can find the specs of this CPU.
