How to? W4300 Bonaire (reader works fine BTW) #19

A picture is better than words often....

This card was badly done by AMD as it was power limited so never gets to its standard clocks (hovers in low 800s) so unlocked power to test and am happy to have got it to 1000 with identical performance to an R7 260 Bonaire but with 4Gb :-) I've tried to mess with undervolting to keep temps and fan noise down but no idea how (if I put numbers in the voltage column of the Frequency table GPU fails to boot at all). I did leave them untouched and moved the frequencies up on the lower entries so it hits 1000 in entry 4 but ideally I'd like to be able to leave the table as the stock table and just lower voltages for each.

How (please) ??

You can try to use the voltage values of lower entries. in example you copy the value of dpm 4 and paste it to the dpm 5 6 and 7. Those values are kind of offset values, not actual voltages. So using a lower state voltage offset is comparable to using a lower voltage. From what i recall you need to do that for all tables to avoid glitches.

The Voltages are listed in the VDDCI states table above (you could try to edit those instead but no guarantee either x).

Thanks, it at least made the BIOS look tidier but i dont think I am getting lower really. I tweaked TDP down so its 55W vs 50W stock and I've upped performance by 77%. Happy really!
