    Most probably because "Polaris" is for polaris cards.. a.k.a RX models..

    280 = Tahiti
    370 = Pitcairn
    380 = Tonga
    290/390 = Hawaii
    Nano/Fury = Fiji
    RX** = Polaris

    I think this is great results, and the max you can get from a 380 these days.
    I'm not 100% sure about this, but i think the DAG size increase affects these 4G tonga cards.

    Cant say about that for sure but with 2.31gb dag file i dont think they are.
    My card crashes after 30 sec or so on anything above 1625mhz on memory, but i managed to get some readings with 1750 on memory and it gives ~24.5Mh/s so if your lucky and get great memory overclocker card you can push nice hash with tonga.
    If i manage to get 14-14-18-18-54-16-88 timings on 1425 and 1500 stripes and have it stable at around 1600mhz i think even my cars could push up to 24Mh/s but i still didnt figure out how those stripes are written.
    Mine and most of other R9 380x have this timings on elpida chips
    Memory Timings (Elpida)
    tRCDW-tRCDWA-tRCDR-tRCDRA-tRC-tCL-tRFC
    200 MHz: 0-3-2-3-7-6-12
    400 MHz: 0-3-5-5-15-7-25
    800 MHz: 5-5-11-11-31-11-51
    1425 MHz: 16-16-21-21-57-18-92
    1500 MHz: 17-17-22-22-60-19-97
    1750 MHz: 21-21-26-26-70-21-113
    I found powercolor r9 380x with this timings
    Memory Timings (Elpida)
    tRCDW-tRCDWA-tRCDR-tRCDRA-tRC-tCL-tRFC
    200 MHz: 0-3-2-3-7-6-12
    400 MHz: 0-3-5-5-15-7-25
    800 MHz: 5-5-11-11-31-11-51
    1000 MHz: 9-9-14-14-39-14-64
    1250 MHz: 13-13-18-18-50-16-81
    1375 MHz: 15-15-20-20-55-18-89
    1425 MHz: 16-16-21-21-57-18-92
    1500 MHz: 17-17-22-22-60-19-97
    1625 MHz: 19-19-24-24-65-20-105
    1750 MHz: 21-21-26-26-70-21-113
    2000 MHz: 24-24-29-29-79-26-129

    I hoped just copying 1250 or 1375 timing stripes from powercolor bios into 1425 and 1500 stripes in my bios would work but all trys, even just flashing powercolor bios on my card ended up in windows startup loop.
