for testing use original bios and you could copy the lower straps to 1500 and see how it performs, lock gpuspeed max at 1100 @ 0,9v and check for memory erros and hashrate
Actually i put stock saphire pulse 560 bios which i found on internet and so far works ok.
1300 clocks ,1750 mem all shaders.
Works without errors even if i push it up to 1800.
Still haven't got tools to put heatsink down to check memory chips. So i'm little bit afraid to put 1500 timing to 1625 and up.
12 Mh, before was 9 -10. so atm i'm happy. But if chips are 1750 will mode it more
