May I ask what your config is to get 460 out of those cards? I can't seem to get mine above 420.
sure, i've undervolted using VBE7 to 1.1V and i'm using SGMiner 4.1.0-73-g80e6.
i know of others who have got upto 480 stable but they're overclocking too much for my liking and i cant get my MemClock to go above 1400 anyway. i think my cards might last a bit longer like this.
