Hello,
They will not be marked by grade. As it states on our website:
- Chip grades: Chips come in four grades of performance. Chips are
sold in mixed grade lots. A grade has 16 engines, B grade has 15 engines,
C grade has 14 engines and D grade has no less than 12 engines. All chips
run at a minimum of 250 mhz. Higher grade chips will run up to 294mhz.
The percentage distribution in each lot is 60% Grade A, 20% Grade B, 15%
Grade C and 5% Grade D.Regards,
