Polaris Bios Editing ( RX5xx / RX4xx ) - Page 128

post #1271 of 3337
Hey guys,

Trying to implement the timing strap mod for my Sapphire RX480 Nitro+ 4GB (Elpida Memory) but when I go to backup my stock BIOS the timings are completely different to anything I'm seeing anywhere else.

I don't have the 1500, 1750, 2000 straps..

Did Sapphire change the stock BIOS?

Check the screen shots.

Any suggestions?

Cheers!

@biggee

Send your BIOS .rom dump and I can help out... 1888MHZ is totally possible and will work fine on ram.

Core we wouldn't want to push past 1150mv/ 1313mhz unless you want to click Reset everytime you wanna game... I think it also sort-of Resets Automatically if you tell Trixx to Start With Windows...

I would try 1313MHZ/ 1188MV in 65288... Click Reset or Have it Start with Windows if you want the extra 38 millivolts to keep artifacts to a minimum.

I tested 1389Mhz 1888Mhz and here I show the voltage before after clicking reset in Trixx... Polaris Bios Editor or the Driver doesn't allow more voltage right away...

1389Mhz is not possible because I looked at my RX 460 ASIC Quality and it's like 50%... So I receive 50% loss from Input/ Output power on XFX PCB.

The RX 480 However probably can but you will need to click reset. For absolute stability you can get away from 1313MHZ @ 1188MV which runs at 1150MV until you click "RESET"... It doesn't crash however if you didn't click "RESET" while at 1313MHZ...

1389MHZ Needs 1257MV but that 0.90479% goes out the window past 1313MHZ because VRM Temperature cannot handle hardly anymore than stock voltage even with Copper...

That 0.90479% is only accurate up to 1313MHZ for RX 460... You may be able to run RX 480 4GB @ 1389Mhz Core @ 1257mv with 1888Mhz Ram on STOCK Untouched Memory Strap...

you have
- to mod the straps with hex-editor
- to fix crc-sum
I can do it and did It.

hello

rx480 red devil 8gb recnt owner here. OCed the card at 1450 core and 2250 memory with +48mv, stable in synthetic benchmarks like Unigine or heavy gaming sessions.

Original BIOS is limited to increase power limit by 5%(attached called origin6feb), downloaded and flashed the attached +50% limit BIOS but it would crash my PC as soon as I start benchmarking or playing a GPU intense game.

trying to modify my original BIOS just focusing on Power limit to add this 50%, flashed it but it would also crash my PC, even worse, making it to start in VGA mode staright away after reboot

if somebody could share some light to understand what is happening

@NoLive721 I have the same but if you feel the need, I made a bios for you... Still with 5% max TDP limit. However the limit has been increased from stock to about 25% as is... I for one always have issues beyond stock TDP but I found I could pull a tiny increase. Take note, you may need to Reset Trixx to yield extra voltage... I believe 65288 on Polaris is 1.1500v. So 1.188V is 0.038MV or 38 millivolts extra.

thanks chris, appreciate the quick reply and time spent to build this BIOS but its giving me also reboot in VGA mode.....

looks like anything being done in POWERTUNE out of the original BIOS which came with the card get the card to crash.

the BIOS I downloaded from TECHPOWERUP (called POWERCOLOR XXX in my attachments)at least was allowing me to start Windows normally but would crash the card as soon as the GPU gets under load

not sure whats wrong here. I have reset Wattman to defaults after flashing your BIOS, will try not to do to see if that makes any difference but I doubt it:o

Hello!

Will this work on the latest driver i.e. 17.1.2? Please let me know.

Download the modified kernel driver here: http://bit.ly/2h0NpwR
Download the Pixel Clock Patcher here: https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher (needed for the windows driver signature workaround)

1) Navigate to the amd driver extraction directory, usually "C:\AMD" then go into" Win10-64Bit-Radeon-Software-Crimson-ReLive-16.12.1-Dec7\Packages\Drivers\Display\WT6A_INF\B309333"
2) Extract the modified kernel driver in the "\B309333" directory overwriting the file
3) Uninstall current amd drivers normally and DO NOT REBOOT when asked
4) Reboot with advanced options like so:
5) Press and hold the Shift key on your keyboard and click the Restart button.
6) Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
7) When your computer restarts you’ll see a list of options, press F7 on your keyboard to select Disable driver signature enforcement.
This is needed only ONE TIME to successfully install the modified kernel, in the next reboot the driver signature enforcement will return to normal.
8) Install the driver normally with setup.exe in C:\AMD\Win10-64Bit-Radeon-Software-Crimson-ReLive-16.12.1-Dec7
DO NOT REBOOT WHEN ASKED
9) When the installation is finished run the atikmdag-patcher.exe (this will take care of driver signature for windows so we no loger need to disabled the enforcement with F7)
10) Press yes to patch the file
11) When finishes reboot the pc and enjoy your modified bios

Hello!

Will this work on the latest driver i.e. 17.1.2? Please let me know.

PS. Sorry, double post.

MSI RX 480 8GB Gaming X Custom Backplates Crossfire

Hi guys I'm at a loss here I can't even keep heaven looping with default settings with this crossfire configuration or temps will go up to 89 degrees with both fans on both cards at 100 percent. I just purchased these last week. I have noticed differences in the bios from my newer card so I'll attach both. I also tried the infamous 153 bios. I have a 1000w psu a really clean build no airflow restrictions water cooled processor so i don't understand why these get so damn hot at stock settings.

Won't let me attach so here's a google drive link:
Newer Bios Purchased 2/8/17 https://drive.google.com/file/d/0By6GrtPmV39FMjQwTmRhbnlrcE0/view?usp=sharing
Older Bios Purchased 2/1/17 https://drive.google.com/file/d/0By6GrtPmV39FMGROaXIyLXZDU2c/view?usp=sharing
153 rom that msi live update sometimes shows and sometimes doesn't https://drive.google.com/file/d/0By6GrtPmV39FZ0c4WXFuVmszYkk/view?usp=sharing

Ok so if anyone can help me figure out how to keep these things cooler that would be awesome i don't mind if the performance is dropped a little the second card will make up for that. Thanks.

Edit: With clocks at 1303 default everything except fans at 100% the top card is reaching 89 degrees the bottom card settles in the high 70's this is after looping heaven maybe 2 times so doesn't take long. I have not noticed any thermal throttling both clocks stay at 1303 but dang 89 degrees seems to high to me and before anyone recommends RMA i have benched both cards independently and they both work like they should staying in the high 70's maybe peaking a bit over 80.

I think i should post this here, too. Everything the Polaris Bios Editor can change, well, except vram timings, is also to be found in "PP_PhmSoftPowerPlayTable".
It is a 1:1 copy of the PowerPlayTable found in the bios. Therefore PBE was a big help, i only had to compare bios files.

U don't need a signature, don't have to flash your card, and it works just the same as a real bios mod.
I used a reference RX 480, XFX Black Edition. Should work with any other Polaris card.

howto:

Install MSI Afterburner
Goto Settings -> General -> AMD Compatibility properties -> activate "Extend official overclocking limits".

This will create the registry entry "PP_PhmSoftPowerPlayTable" at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000
last 4 digits may vary due to crossfire or whatever..


Save the reg key (the four digit thing, right click -> export) and delete anything except "PP_PhmSoftPowerPlayTable":

U can now make your changes here, or use regedit.

the maximum power limit increase. +50% -> hexadecimal: 32


FF08 (65288) is for P7 state, P6 FF07.. search for 08 FF instead, and here we are, all values from 800 to max as found in polaris bios editor:

these^^ are the exact same values, the polaris bios editor would change.
example: 1200mV -> hex: 4B0 -> B0 04 instead of 08 FF (P7)
don't make a mistake here wink.gif

If u don't change this byte from 0F to 0B, memcontroller voltage will be the same as vcore.
Some customs have this value already set, else i wouldn't know about it.


clocks for each p-state are found here.
1400MHz x100 -> 140000 (dec) -> 222E0 (hex) -> E0 22 02 (bytes)


TDC(A) and max power limit (W) is found here:

110A (hex:6E) TDC and 115W (hex:73) max power limit (XFX Black Ed.)

vram clockrate, again x100:

200000 = 30D40 -> 40 0D 03


^^these values also can be found:

1000 = 3E8 -> E8 03, followed by the frequencies.
30 75 ->7530 hex -> 30000 (300MHz x 100)

vram limit:

here 2300MHz

fan:

Temp Hysteresis: 3
min Temp: 40° x100 = 4000 -> FA0 -> A0 F0
med Temp: 65° x100 = 6500 -> 1964 -> 64 19
high Temp: 85° x100 = 8500 -> 2134 -> 34 21
min PWM: 20% x100 = 2000 -> 7D0 -> D0 07
med PWM: 40% x100 = 4000 -> FA0 -> A0 0F
high PWM: 60% x100 = 6000 -> 1770 -> 70 17
max Temp: 109° x100 = 10900 -> 2A94 -> 94 2A
max PWM: 100% -> 64
Sensitivity: 4836 -> 12E4 -> E4 12
max RPM: 2200 -> 898 -> 98 08
Acoustic Limit: 910MHz x100 = 91000 -> 16378 -> 78 63 01
