thank you for strip the technical informations i posted
and instead stating that i am pedantic

i used google to search the ark database for you and provided the
information that this CPU simply has no SSE4.1 capability, frankly
the E7330 as built by Intel also has *no* SSE4.1 support

Status: End of Life
Launch Date: Q3'07
Expected Discontinuance: Q1'2010
Processor Number: E7330
Lithography: 65 nm

again http://en.wikipedia.org/wiki/SSE4#SSE4.1
These instructions were introduced with Penryn microarchitecture,
the 45 nm shrink of Intel's Core microarchitecture

and no you do not just throw away a CPU like a Xeon-E7 which
costs around 2000 €
