What will be the expected monero hashrach for radeon 7 after applying SRBminer 1.8.4 or 1.8.5?

As I had installed the latest radeon GPU driver ( Adrenalin 2019 ver 19.4.1) and then upgraded SRBMiner to 1.8.4 and tried to tweak using + on keyboard screen shows  "successfully applied tweak profile 1~ 5 to supported devices", But seems no change on hashrate.
When i use 1.8.3 version, Monero Hashrate was around 2930 H/s and still remain same no change found.
