Performance is exactly the same as with the stock rom - pulling 235watts at wall (entire system), 87watts according to gpu-z, hashing at 29.3mhz or thereabouts at 2200mhz memory (the highest my card can handle without crashing).
Am I missing something here? Did I miss a step? Surely this rom will change my default out-of-the-box performance or power draw? My understanding is I don't need to disable signature checking or anything like that for 16.9.1 drivers - I hope this is correct.
Thanks for any guidance - it seems like I am doing something wrong I think...
Hi Ozoner99. From your statement your cards are working CORRECTLY. If you run a fully stock XFX 480 reference ( the same cards that I have) you will mine at about 24.6 MHs.
With these mods you are getting about 5 MHs more hashing speed while reducing the energy draw. My GPU-z consistantly showed around 115-120 watts on stock settings, and with the modded bios it is the same 87-90 watts as you said.
Congrats on the successful mod.
You can always try reflashing your card back to stock bios and comparing to that.
