I have just got a new CPU for my machine, an AMD K6-2+ 450MHz. Replacing my K6-2 500MHz.
I set the voltage to the specified 2V.
Here are some the results I have got.
(SiSoft sandra 2001 se)

first the K6-2 500MHz as a base line.
Drystone-------1186 mips
Whetstone------ 594 Mflops
Integer MMX----1507 it/s
3DNow----------2166 it/s

K6-2+ 450MHz 100X4.5
Drystone-------1124 mips
Whetstone------ 541 Mflops
Integer MMX----1372 it/s
3DNow----------2194 it/s

K6-2+ 500MHz 100X5
Drystone-------1250 mips
Whetstone------ 602 Mflops
Integer MMX----1526 it/s
3DNow----------2194 it/s

K6-2+ 550MHz 100X5.5
Drystone-------1376 mips
Whetstone------ 663 Mflops
Integer MMX----1680 it/s
3DNow----------2416 it/s

K6-2+ 570MHz 95X6
Drystone-------1428 mips
Whetstone------ 688 Mflops
Integer MMX----1745 it/s
3DNow----------2508 it/s

Now I tryed 100X6+600 but she wouldn't post.
I was suprised because she is rock solid at 570MHz (24 Hour SETI run, no errors) If this was a normal K6-2 I would increase the voltage incrementally to a max of 2.7V gain stability.

nullMy question is what is the max voltage that a K6-2+ will run at before frying?

I would realy like this machine to run at 600MHz,I would prefer to have the FSB at 100MHz rather than 95MHz.
