Only difference I believe is that the GHZ is OC'd to a GHZ or more, so just overclock the core one to match the speeds of the other one. No need to flash the BIOS and mess things up. Screwing around with video card BIOS's is dangerous stuff.

Flashing a BIOS isn't going to turn it into a GHZ and make it run at those speeds. If it won't run at that speed, a BIOS isn't going to help. You may have to increase the voltage a bit, or, that card just won't do those speeds. Add small, small, small, voltage increases and test, or accept that it just can't do it.
See, when GPU companies or CPU companies make chips, they try to make a batch of the fastest chips possible. Then they test them. Ones that past at say 1200CORE speed, get sold as GHZ capable chips. Ones that fail, they test slower, and they get sold at the speed they are stable at. They don't make 100000 different model chips for each different speed. They make one 7870 based chip, and test speeds, so your core chip wasn't able to obtain GHZ speeds at AMD, so they sold it at a lower speed.
More voltage make help. Try 1100 and see how it goes. Not going to be a huge difference between 1100 and 1200 anyways.
