For all of you guys i made a custom bios from the one in the main post.
You won't need any wattool,wattman,afterbuner,trixx or any other software of that type, i set everything in the bios like Insider00 did with wattool, so :

Def gpu clock : 1144 Mhz
Def mem clock: 2150 Mhz

Mem straps 1625
VDDC (gpu voltage) set at 925mV
TDP 120w
Set fans to hold cards at about 70c, so you don't need fan regulation either

Before flashing remove ALL software that you used before for manipulating (wattool,wattman,afterbuner,trixx...).
Then clean all video drivers with DDU.
Flash bios.
Reboot, reinstall video drivers.

Test.

worked great but my 480 nitro still keeps the fan at 0% any insight in what might be happening? also the newest driver didn't recognize it, can the ATI pixel clock patcher solve this or not??

hey guys

First of all, thanks for the BIOS Doktor83.

I have a strange issue:

Doktor83's bios has the temp settings:

med temp - 45
high temp - 56
max temp - 73

And in MSI Afterburner i can see the max temp limit is 65. Of course after my cards reach 65c - reboot.

But the original bios:

med temp - 65,
high temp - 85
max temp - 109

AS for me, that is some kind of bug. Any suggestions ? Should i change the temp settings via POlaris and than flash the cards again?

Thanks!

Best is to modify your own bios, less chance to brick card.

What's the difference between hynix and micron memory and how to check, which I have?

Different manufacturers.
You can see in gpu-z

Thank you. Now I know I have Micron. Which one BIOS is correct one to download and where can I download it?

Thanks doktor83!

Your rom allowed 4x Sapphire Nitro 480 8GB reach 29.3MH/s (Micron).

I tweaked the settings a bit, but I mostly needed the straps as PBE wouldn't work.

1100 GPU/1000 mV
2050 Memory/1000 mV

Fan minimum 50% makes them run smooth.

I can't confirm his rom is best, but at least the straps are changed. What strap mod did you perform?

how lucky you are
i got artifacts on doctor83's bios

I think Micron might be hit or miss maybe?
If it is of any use, the ASIC qualities in GPU-Z are 70.4%, 68.7%, 68.3%, 79.5%.

Has been running stable 29.3MH/s for 3 days now. Lets see if it crashes eventually.

No, it 's a obvious sign of too much OC.
Hynix won't be stable over 1950 MHz with the common timkng straps.
Even with custom straps you are lucky if you can go over 2000 Mhz.
1950Mhz with 1500 timing should bring you about 28 mh/s.

yeah my hynix 480 and 470 cards i just used 1900-1925 some even as low as 1850 just to keep them stable

my feeling is 1 or 2mhs more hash is not worth me rebooting a rgig once everyday
