Probably 6Ghz hynix memory card. These can do 13.5 tops with some mem. errors. I did not found any timing strings for it. I use 1625 strip in 1750 and that is best I can do with it. Mem string for standard hynix don't work, as it simply can't reach more then 1900mhz and all the timings target 2000+
Is it H5GC8H24MJ? For this type those free available aren't very good. Few months ago with some testers we've made good performance timing for XMR and a little bit worse timing for ETH (still need some love). But it was mainly for RX 570 that they had max 1500Mhz strap si I'm not sure about hashrate for RX 560 but RX 580 with this type can do 950H/s with pretty nice power consumption, ETH is weaker around 31MH/s.
About 450H/s cryptonight, 14.5MH/s ethash with rx560, that Hynix memory is not good at all
