390x bios leaked

bro !!! not understand me as 290 x plays comfortably passes the memories 1500 and 1600 !!

 

Not every card will overclock the same. There are certain Elpida cards out there that doesn't play nice with memory oc.

 

This is aweseome

 

anyone tried to flash bios for an 295x2?

 

this bios is not working for me :/ cant install drivers with it

 

i flashed the 390 pcs bios on my 290 pcs, its working fine, but my card is still detected as 290, any idea how to change that?

 

I hope to come out the BIOS Sapphire 390 TRI- X

 

Hi guys !

I own a Sapphire 290 BF4 Edition and I flashed it to a 290x successfully .
Sadly none bios except PT1T worked for me but today I found something very very interesting !

So I flashed on my 290 the R9 390x modded bios by NETKAS and I was happy to see that it unlocked my shaders and gives me back 2D clock mode (which is disabled on PT1T bios).

I used 1105 / 1375 Mhz (my previous PT1T overclock) and launched Witcher 3 to check the results in game.
But what I found was totally crazy...

The settings of the game are maxed out with 1440p resolution and I added .ini tweaked shadows and foliage

R9 290 with R9 390x bios results :

Min FPS : 24
Max FPS : 28
Max VDCC : 1.281v
Max VRM1 POWER : 241,500W
GPU Max TEMP : 50°C


R9 290 with PT1T bios results :

Min FPS : 30
Max FPS : 34
Max VDCC : 1.227v
Max VRM1 POWER : 111,625W
GPU Max TEMP : 53°C

For the same scene in the game I gain 6 FPS and draw much less power...

I dunno how this PT1T bios manage this crazy thing but here is my question :

Are you guys able to add 2D clock mode to PT1T bios ?

 

I've changed XFX PowerPlay table to Powercolor 390's just to test
Dunno if it is safe, but... Now I have temps of 290x

 

what part of bios is powerplay table?
or please share your bios so we can see how you made it

 

For XFX bios it is

Code:

data_table  0000a398  #0f  (PowerPlayInfo):
Size         0294

 

hmm i see that you can get whole BIOS structure from atomdis

 

Hi. do you send me the bios, with 947mhz core / 1250 mems, with elpida compatibility?

Thx you

 

is there some deeper research on what changes can be made to 290/390 vbios?
i want to mess with my fan control (as i have aftermarket cooler)

 

Code:

7C15 (temp1) = 157C = 5500 = 55*C
8C23 (temp2) = 238C = 9100 = 91*C
4826 (temp3) = 2648 = 9800 = 98*C
D007 (%rpm1) = 07D0 = 2000 = 20%
7C15 (%rpm2) = 157C = 5500 = 55%
581B (%rpm3) = 1B58 = 7000 = 70%
4826 (temp4) = 2648 = 9800 = 98*C

Change needed values(red), remember to switch them xx<-->xx, change 01 to 00(blue), save, fix checksum. GL HF.
But not all roms have this table.

 

thanks for this
i allready found that there is no such map starting with 03 06 in XFX 390X bios

but will try on old 290X bios

edit:
can you please recheck this? if its correct modification?


i changed
temp1: 55C to 50C
temp2: 91C to 70C
temp3: same as before
temp4: same as before (this is shutdown temp?

rpm1: 20% to 50%
rpm2: 55% to 75%
rpm3: 70% to 99% (can i go to 100%? )

 

Those are pretty save temps to me, AMD themselves claims that their chips is completely save till above 95°C

 

@DDSZ: thank you soo much it works perfectly
hope there will be 390X bios with this table so i can use it

 

On unedited XFX bios 90*C on core and VRM1, only after 5mins of 3dmark FS Extreme.

 

yep VRM on XFX bios heats alot more but if you can swap powerstates from other cards i think this issue will be fixed

is someone working on R9 290/390 bios editor?
