Modified ram timings AMD 290 pro's

Are the gains from flashing to a 390(x) bios from memory times alone? Or is there more going on than that? Surely by tightening the timings, you are limiting its OC, and thus not really achieving anything (or maybe making things worse) once the OC is dialled in?
Or are fooling the drivers into thinking we have the newer card and getting the performance that AMD purposely held back at a driver level to make the 390(x) look better?

Thanks for the reply, I'll give it a miss methinks.
Flashing the 390/x bios alone is a little step up, but these have actually been modified even further. Tighter timings than even the factory 300 bios has. Thats why it's specific to get the bios for the specific type of memory your card is utilizing. Also the timings are carried up through even higher overclocks. I've had my cards at 1150/1475 stable which at less voltage than before the bios swap.
Not saying it's a game changer... I've had these cards since launch and it's just nice to be able to give them a little bump in their older age
getting some much better memory overclocks on my Tri-X after putting 390 bios - maybe the latencies are a bit slower with this bios ? but overall performance is better
with these clocks the card managed 2900 on Valley Extreme HD and 5755 on Firestrike Extreme

Do you have original bios scores and numbers? It would be nice to see a comparison.
