The Dell Radeon 9700TX is just a branded straight 9700 card. Stock clocks
are 270/263. You are at the limit with this slow RAM. 17Mhz over stock for
a card with slow RAM is typical. Ramsinks may give you a bit more, but don't
expect miracles.

Would flashing to a Pro BIOS give me a few more mHz? I was really
hoping to get a little bit closer to Pro speeds on RAM...

The only way a different BIOS version can give higher overclocks is by
relaxing the memory timings, which is detrimental to performance. Don't even
bother.

Your best bet is to crank up the memory voltage a little. There are plenty
of such guides on the web. It could be as simple as penciling in a couple of
resistors (be sure to measure with a multimeter afterwards). RAM sinks will
be necessary, as heat generation increases with the square of voltage.
