FYI, 5870 is a 150W card and gpu is one generations ago, 280X is a 300W card, I don't think you will see any big further hash rate increase in 5870...
sure you can pick up 4 old 5870 card for the price of 1 new 280X, but you need to buy another power supply to give you more PCIE Power cables...
also, 5870 was much hotter.
Topic: Sgminer HD5XXX AMD gpu cards support (Read 2379 times)
bump
I see there is a lot of progress of Sgminers for new 280/290 AMD cards.
I have tested all of them and there is impressive speed boost, not to mention that supports new algos.
However there is no progress for old HD5XXX cards.
No speed progress at all and no X15 mining.
With new Sgminers that can be found on the forum or elsewhere,
my pc just freezes to white screen, or just become unresponsive.
No matter what i combine, what kernel or config i use.
If someone has experience or knowledge to modify Sgminer to be able to mine at greater speed on new AMD drivers,
or even to mine new algos like X15, thousand of miners worlwide will be grateful.
We all have some old GPUs that can be involved into mining as well as new 280/290.
Cards that needs to be supported are:
Present speed that i can run Sgminer on algos X11 and X13 is:
X11
HD5850 =1900
HD5870 =1750
HD5970 =1750+1750=3500
X13
HD5850 =1300
HD5870 =1150
HD5970 =1200+1200=2400
