I had a play with this since I also see poor quality with my 761 card,
trying cpump values of 1, 2 and 3 for the 470..750Mhz range with your
patch to also do cpump << 6.
I ran tzap for 60 seconds on a mux at 665Mhz and recorded all the ber
values, extracted into a spreadsheet:
cpump 1 2 3
average 13804 6071 5365
median 9618 5494 4758
which is still not exactly great but it seems cpump=3 gives the best
results; I'll do some more testing with this patched driver and report
back later in the week. If there's anything else it would be useful to
test let me know.
