Hey guys, got some questions(first post, be gentle

)
been looking at overclocking my 4 A4+'s but it seems that my miners only have the dropdown for 1044 and 1100. The Card type is G19 with a FW of 29-12-2017
Is this normal as I see everyone saying 1152 should be avalable. (current hash rate of ~628 , vid 25, Mhz 1044)
furthermore Is there really any reason to overclock as a 10% increase in profit is negligable for possible miner damage??
Im also currently mining verge & gamecredits on miningpoolhub's pool and earning ~£5 gross. Only reason I ask is I swear the ROI was less than 400 days when I got the machines.
