I have just got a Cyrix CPU with a glued on fan/heatsink. Trying to figure out what the processor is from the code on the bottom.

Bottom has (C)(M) 1995-1997
Cyrix
VV7SJ2848AR

It came on a Delhi-III motherboard.
I can't know the settings are correct but this is how it came.
The CoreVCC dip switches are off, on, on, off, according to the dipswitch, however I think its been put on upside down as the manual indicates down is ON opposite of the dipswitch block ink. on, off, off, on would be 2.9v which is valid for a Cyrix 6x86MX or M-II
Its setup for 100Mhz SDRAM only
The jumpers seem to indicate a IBM/Cyrix M-II PR300 (J3 = 1-2, J4, J2, J9, = 2-3 | J11, J12, J13, J14 = 1-2)

Anybody know it really is a IBM/Cyrix M-II PR300?
