390x bios leaked

we tested 290X vs 390X on our czech forum and there is some small boosts in 3dmark score (like 200 points on same clocks) i know that cards are same except that fuse and different clocks (and some bios modifications)

next 200 points was from driver 15.15 so it was around 7% graphic score increase vs 290X + older 15.1040 driver on same clocks

dunno how its now on 15.7 WHQL if 390X still have driver advantage or not

EDIT: just flashed one of your modified bioses and it looks like its on par with 390X in 3dmark also very nice VRM temperatures (i have gelid icy vision v2 + modified reference cooler plate for VRM cooling

 

Must be the tighter memory timings at work.

IIRC 390X has tighter timings, again from what Stilt said in another post! .

He's done VRM work on bios.

 

The GPU is identical.
ODMs change their PCB design from time to time anyway (revisions).

 

Wasn't really serious just wishful thinking lol,
i just wondered if it was possible to edit a r295x2 bios and add the 390x name into it so that drivers would detect the card as R390x and install drivers and keep name R390x there for keeping the data all the same... so when you went to install none modified amd drivers it would detect the card as 2x 390x cards in your system

but its probably to hard to do that and as you said the id would be different and fused so no point in trying that out lol

anyway im just looking for voltage changing on my card up to 1.400v as this card is fully watercooled with water block


-----------------------------------------

Also guys could you add an advanced setting tab on the hawaii editor and remove all but the voltages that are needed to make it more simplified for people

for instance

put names for

UVD voltage
3D Voltage
2D Voltage
3d clocks
2d clocks
UVD clocks

you get the idea just keep it simple as the program is beginning to look a lot complicated and for people that dont know what there doing could damage stuff.

 

its interesting to see 7+2 phases as its probably still controled by IR3567B or there is some new controller?

@Plug2k: you can change codepath for driver its explained in some thread here on guru3d i try to search and send it to you

also 1.4V is kind like 800W under load from for R9 295X
i dont really want to keep it that simple as this still request some knowledge its better when its complicated so people need to search on forums for such changes

 

sweet

let me know guys when the hawaii bios editor has full 295x2 added so i can test it out as i think your adding compatibility for voltage changing and i will let you know if it works

 

Same controller, Link:- http://www.techpowerup.com/reviews/MSI/R9_390X_Gaming/4.html

 

well using msi afterburner the max i can get out of the voltage is 100mv+
ranges around 1.320-1.340v

that nets me around 1180mz / 1690
if i had 1.4v i know i would be able to hit the magic 1200mhz/1690

under load with those volages i net around 60c in temps and thats perfectly normal considering the default cooler nets around 75c then throttles the card to protect it from damage ect

so even if you added 1.4v the card would not damage it would just throttle once the temps hit 75c, these cards have in built thermal protection if you dont got the cooling the card would still be safe.... but if you have the cooling and can keep the card under 70c then its perfectly safe. even like i said going up to 1.4v would still be safe...

 

you can add to 1.4V by console command in afterburner but i dont think its wise decision

not really worth to get 20mhz for such power consumption increase its not linear in this range
you can create pretty expensive brick even with watercooling

 

hehe i will leave it to you to add the highest voltage you think is safe then and i will test out and let you know if i require more hahah

 

problem is that afterburner offset is on top of voltage in DPM7 so i can cap it to 1.4V but if you start PC with +100mV offset in afterburner the core gets 1.5V which is not nice

i will add that warning into software so everyone know to reset their offset before flashing new bios
i also found that C# datagrid is kind of pain to work with so it may take a while to implement these limits

 

np mate take your time
in no rush, make it as safe as possible

 

someone allready messed with DPM0? can i set it under 900mV without issues? as from my experiences with afterburner my card can go as low as 0.75V or idle voltage can be edited only with offset?

 

I think you can, you may recall that image I posted with range of voltages, that's from AMD press release stuff when Hawaii launched.

 

ok just tested with 900mV and it WORKS!!! feels like Christmas

900mV in bios is smth like 891mV in afterburner (which is interesing as 925mV was 931mV in afterburner before)

now im interested in other things like:
is there a way to decrease power consumption while 2 monitors are connected?
is there a way to underclock card even under 300mhz?

 

I know the feeling! , just about to do the same on lower DPM states.

I'd first edit the base clock up the top of powerplay, then set the other tables with freq. lower.

 

i allready tested that you cant go under 300mhz but maybe there is other section of bios with this value hardcoded
blackscreen on 850mV with stilt bios (i not calculated that value i will test with proper 6.25mV calculation and see if its too low or just wrong number) and automatic checksum fix works too

 

got the latest version of hawaii i can test guys
also i would probably suggest that you dont mess with the idle voltages and better would be to mess with the bluray UDV voltages and clocks as those would indeed work out better for reducing power when watching bluray movies

as clocks default to 950 or something and boost memory to 1250 or something when watching UVD or bluray .... those could be brought down to 500/1000 or something without sacrificing power and speed

 

ok will add "burned cards" tab into program to scare potential users

 

hahahah awesome
