Polaris Bios Editing ( RX5xx / RX4xx ) - Page 149

post #1481 of 3385
@xrelic reference 480? Sure send the bios. It's tricky lining up the fan on these cards. It kind of also goes on the VRM temp (unmonitored) so it's a good thing it's running high in many ways.

its a nitro rx 480 8g i dont mind that it runs high on the fan curve but it takes forever to go down like i be doing 90% fan speed at 30c after i am done gaming

Manually edit the bios with an hex editor and then use Hawaii bios reader to fix the checksum. I use it even for my hd6990

"Min Acoustic Limit
This is the GPU freq above which the fan will try to sustain the achieved RPM / temp ratio. Set it too low and you fans will take ages to slow down after heavy load.

Once the GPU freq drops under the Min Acoustic Limit, fans go quiet instantly, as soon as the temperature drop."

Found this on the forum

Ok Today will try with the Hawaii Bios Reader to fix the checksum smile.gif

The Hawai Bios Reader successfully signed the File, no more blue screen. Now trying to find the optimal strap for micron.

Any suggestions? Currently Testing the 1750 Strap.

The 1750 Strap is yielding positive results.

Try the 1625mhz strap but keep the last 8 timings from 1750-2000mhz straps(try what's best) like i did in the "mix" example.

I'm now playing with a XFX HD6990 and the last 8 values helps a lot at high mem clock(i'm now at ~145GB/s using the Hynix AFR timings from the HD7970. 120GB/s stock LOL)

Ok will try. Currently 2065 Mhz is max for the 1075 Strap Timings without any GPU Memory errors.

I must also ask, since I used the Hawai Bios Reader to fix the checksum. How do I set the voltage table, which bios editor to use to set the clock voltages?

I Kept the 1750 on the front with last 8 from 1825 and it yielded better results. Higher stable Clocks around 2100 compared to 2065.

Now just need to modify the core clock voltage table with something.

not on my card it is not instant takes a while idk how many minutes to go down from 90% fan speed at 30c back to 0% idk if this can be fixed by flashing bios or flashing a different bios
