Modded R9 390X BIOS for R9 290/290X (Updated 02/16/2016) - Page 68

When your stock 290 tri-x bios is flashed to card does MSI AB show a GPU core voltage offset, even though you didn't set it?

Best way to test this:-

i) first delete all files starting with VEN in installation folder \MSI Afterburner\Profiles, (this will force MSI AB to detect cards bios defaults on next run).

ii) flash your stock bios and power down PC fully

iii) switch PC on, run MSI AB, when asked reboot to detect card settings say YES

Why I do above is when testing varying GPU core voltage offsets in a ROM (this is different from DPM voltage) I'd get varying results for default shown in MSI AB, as it can't tell the difference between a different version of ROM unless Vendor/Device ID differs in ROM. Therefore it will go ahead and apply defaults of what it noted before, some things it does pick up and update when ROM changes and redetection isn't done.

When you state this "evv at dpm7 for stock is 1.250" how did you get the information? The Stilts app or other method?

I used the Stilts app to get 1.250 for the stock rom. I don't see any offset in Afterburner.

Good news is I just tried flashing the modded one bios again and it works, yt doesn't crash anymore. It still says DPM7 is 1.23125 but it is working so I will commence testing.

I noticed that in GPU-Z the idle voltage went up from 0.96v to 1.00v, and the VDDC went up a bit but the gpu is reading a lower temperature at idle. Not quite sure how that makes sense...

*Edit: Well it worked for a bit then froze on me. I think I'm gonna try adjusting the voltage table.

Don't adjust "Voltage table".

Adjust DPM 7 in all 6 tables to be 1250, as you state a) you don't have global GPU voltage offset using stock rom B) used The Stilts app to get your VID for stock rom GPU clock.

The 6 tables are Gpu Freq. Table and MEM Freq.Table on "PowerPlay" tab, then the 4 you see on "Limit Tables" tab.

Now like mus1mus stated you're getting black screen when using modded bios as EVV (Electronic variable Voltage) maybe too low for your GPU.

How you determine how to set DPM 2-6 is via:-

i) setting MSI AB to same GPU clock as DPM you wanna test. ie if DPM 6 is 977 (plus use corresponding DPM RAM freq.)

ii) check its stability, if required adjust voltage via GPU voltage offset in MSI AB

iii) once you know what offset is stable for x DPM, use GPU-Z "Render Test" (press ? by Bus Interface value box) to get the drooped VDDC.

iv) set DPM voltage manually in ROM, repeat test with GPU-Z "Render Test" to see if you get same drooped VDDC, if not adjust ROM again and check.

hi, my asus reference r9 290 can be fully unlocked to 290x.. can i use the 390x bios mod for 290x into my card?

Okay, I did this and got it working stable but I don't notice much of a difference over stock benchmark wise.

12962 on stock bios http://www.3dmark.com/3dm/9245677? (1120 core 1375 memory +75mv)

13333 on modded bios http://www.3dmark.com/3dm/9245520? (1120 core 1375 memory +75mv)

My card is a terrible overclocker anyway so I think I'll just stick to the stock bios and enjoy the slightly better stability.

Thanks for the help though and it was a nice learning experience.

You can look for a better BIOS.

I did. And it worked.

@gupsterg

FF F1 works as well. Pushed my card further.

So now you found another awesome timing? Great work, impressive core clock.

The fruits are there for the picking. thumb.gif

Still not your card's level but,

Excellent improvement. But FS doesn't scale well as 3Dmark11

That's a nice score either way. Everything over 14k is pretty awesome for a 290. I must see how the ff/f1 thing goes for me, i can atleast contribute with some more testing.

Maybe you can try EE-E1 first. thumb.gif

Hey, Always follow the semantics. FF FF corrupts the screen

FF/F1 just made things worse for me. Tried it on a unmodified tri-x bios and it scored bad, couldn't get high memory clock and wasn't very stable (however 250mv fixed that, i get somewhat low voltage under load). So i will try some other different combinations.
