Polaris Bios Editing ( RX5xx / RX4xx )

Hi all, long time since I was among the first to mod my Nitro+ RX470 4GB into RX 570 :-).
Recently sold my 1080Ti and I am back to my Nitro+ RX 470 4GB Hynix.
Any new recommend bios for it? (570/580?)

It's best to mod your own BIOS. The only thing you really need to do is mod the memory straps.

I don't like the RX 470/480 bios since the performance is much lower then RX 570/580 Nitro, but since my voltage controller is different then what used in the new Sapphire Pulse/Nitro 570/580 the Power consumption readings are wrong, but the card works great even with Nitro 570 1410Mhz bios.

i got an Asus rx 580 dual OC 8gb. i obeyed temps off my VRMs and wondering if its normal that just VRM1 goes up to 80 degree and vrm2 stays on like 25 degree all time?
and also i got Hynix memory and found so far no good timings for it main point is gaming

Just copy the 1500MHz strap to the 2000MHz strap.
I get about 205-207GB/s in OCLMembench at 2000MHz memory with the 1500MHz strap.

another question that makes me wonder with OCLMembench. Why the last 5 Chunks are showing only 5.2gb bandwith from 7552 -8192MB that i got from the day i installed my card

I think this is due to drivers memory reservation and such.

Hi, I have a problem with Afterburner and OverdriveNTool, changing the core clock, the voltage is droped fron 1.206v to 1.15v, like you can see in this video:
https://drive.google.com/open?id=1F0...52xqCg-j7kh1P8

Do anybody with an 590 or other polaris gpu see this?.

I think that the problem is that Afterburner and overdriveNTool are not using auto voltages like wattman. It seems that they are using manual voltages. Increasin the clock with wattman and voltage in auto, I don't have the problem. But if I have wattman activated, I see that sometimes the max memory clock is droped fron 2000mhz to 1750mhz, and it can cause instability, so I don't have it activated. I'm using the 18.12.1.1 drivers.

My RX 470 Nitro+ just died :-(, the funny part is that it was with the original bios that I just edited the fun curve because off noisy bearings while surfing the web(unsuccessfully- still activated at 40C), I have placed silent 90mm Fan's under it so the card stayed cool & quiet while surfing web and I just made it to run 1300/1800 vs 1260/1750 stock.

Now who know's if I will get replacement, for no reason the PC just turned off while gaming even tho the temps were OK, now it's completely dead, not recognized by PC and only led's turn on (Fan off).
Back to R9 270 :-(.

I have found one way to solve the problem, is to change into ASIC Profiling table, ulEvvDefaultVdcc and ulEvvNoCalcVddc form 1.150v to 1.206v that is the highest value I see in dpm3. Also I have tested to change ulEfuseMin from 1200 to 1550 to lower the dmp 6 to 3 voltages, but voltages are to low. I have to test a value between 1500 and 1550, because with 1500 dpm 6 is 1.206v.

Afaik with my tests, those voltages are the manual voltages you can see in wattman and OverdriveNTool, and are a fixed voltages for per dpm clock. They are used if you are changing core clocks in Aferburner, trixx, OverdriveNTool, and wattman with manual voltages.

Changing clocks with auto voltages in wattman, or with a registry value in OverdriveNToo,l it is using the stock auto voltages, that can be increased or decreased changing the clocks.

Other thing I see is that if you are using OverdriveNTool without Wattman activated, and you change some value on it, a registry value is added and the manual voltages are used instead the auto voltage ones, so it can cause problems.

To increase or decrease auto voltages, that is a range of voltages per dpm clock. The easy way is to use a voltage offset with AB of Trixx. But there is a second way using some values into the powerplay named ucCKSVOffsetandDisable. It seems that increasing the value by a 6 dec value is incresing the voltage 6mv and decreasing it is dreceasing the voltage. I don't have tested negative values for it, I have tested only up to 00.
480s and 580s have these vales to 00 and I don't know if this is working for them.
You can see the location of these values in the second image. I don't have tested DPM 0 ucCKSVOffsetandDisable that is 80, but it seem it is not increasing the voltage.
