what is wrong with my 280X?
seems 280x beats rx 480 again? LOL!
What miner do you use?seems 280x beats rx 480 again? LOL!
omg, I cry. I don't believe what I'm reading here...
Yeah no idea how you get 290H/s. I am guessing your timings might be modded and its incorrectly displaying the hashrate. I had this happen before with ETH mining.
For Tahiti, the most I can get is 245H/s and that's with a high end 7970 which is maxed out at 1100/1575 with memory straps hacked. The other 280x are all at 230h/s, which is still higher than my RX 470s.
its stock rom, 1100 core 1500 mem
it started at about 230 h/s after mining for the dev fee it started to climb to 290 h/s
there is a problem because the rejects are pretty high.
as of now running time is 16:57, total shares 2054, rejects 242 ...i suppose it is still getting shares like a 230 h/s...and looking at dwafpool it is not far behind my 2x rx 480 rig in shares..
I had a similar issue with a 280x toxic, clocked at 1150/1600. I tried lowering clocks, raising voltage but the card was running wild to up to 320 h/s and a lot of rejects and errors. Lowering intensity to 4 solved it. For some reason, cards even within the same chipset behave differently.
