Amd steppings and what they mean.........

[[XC] Oj101]

Now the last 4 has always been vague but i've always believed them to be the code that determined who tested, time of day, etc etc.....I really don't think its as pertinent unless the guy testing was half in the bag (not likely)

I can clarify the four letter code a tad:

Example: WPMW

First Letter:
A/R = Monday
B/S = Tuesday
C/T = Wednesday
D/U = Thursday
E/V = Friday
F/W = Saturday
G/X = Sunday

So we can see that WPMW was made on a Saturday.

I can't remember what the second letter means, WPMW

The third letter is batch number, A=1, B=2, etc, M=mixed. WPMW = mixed batch.

The fourth letter as a W means that the chip came from Malaysia , if it's not present the chip came from Chine WPMW - EDIT: Regardless of where it came from, chips missing the W at the end don't clock worth a damn in general.

I might be a tad off, it's been a LONG time since I learnt these
