Intel Pentium 4 with dual specs printed on IHS

[Rocketdog]

I have an older Intel Pentium 4 that has two different specifications etched into the IHS.
Etched to the center of the IHS...

INTEL '03
PENTIUM®4
3.40GHZ/1M/800
SL7J8 CHINA
54268637

and etched off to the side...

3.20GHZ/1M/800
SL8BY CHINA
54268637T

I haven't yet tried to install it in a motherboard.
Has anyone seen this before?

That is clearly not right - this CPU looks like some form of counterfeit to me - not genuine Intel.

Evidently a common practice with Intel.
