Sorry - that was really a stupid question!

However, the HIS specs state 378 for the 9800SE and 380 for the
9800Pro

>(380MHz/378MHz)*3024M = 3040M. So the difference is directly a result of

Actually, HIS hav especifications on their Web site for both the
9800SE AIW and the 9800Pro AIW.

I'm really not interested in a very small % speed increase so even if
this is really a Bios flashed 9800SE, as long as the performance is
near the genuine article and runs stably then fine. My worry is it
might not be stable.
I would be annoyed though that I have paid well over the odds for a
9800SE AIW which just happened to come in a 9800Pro box.
