Gigabyte r9 280x v2 voltage lock. Bypass through bios mod? - Page 6

even more strange....i modified my original bios with vbe7 (only the tdp) saved it....so no uefi...and it works fine....

it cant be driver related because i get no post screen at all....right?
can you do me a favour and save it again with 1,25v max? maybe its out of some value range or so.....(but it still does not explain why it boots with one screen attached)


maaaan....thats stupid...

edit:

i donwloaded a hex editor....searching for my voltages.....so 1163mv is 08b4 in hex.....this value is in 8 different rows...

0x03da0,0x03f80,0x047b0,0x04810,0x08730,0x0b1f0,0x0b230,0x109c0,

how do i know which values are the right ones?


EDIT EDIT:

i now can see that you replaced all 1200=B0 04 with the 1300=1405.

Do I really need to change all of them? I found out that if i only change the value in row 0x0b1f0, in vbe7 i can afterwards select the new value. (though i always get a checksum error...and since i am completely new to all this i cannot correct it ^^)


men i hope you can still help me biggrin.gif

I found that only changing the one value would not actually change the value in GPU-Z. What I was going to do was start to change one value at a time until desired results occur. Qick way to correct the checksum is to open the modded file in vbe7 and then just resave it. It will correct it for you. Lets keep playing with this until we get it right.

Here are a couple more links that will also help you out.

The Stilt's memory timing adjustments:

New scrypt.cl by IG0RB:

Both did great for this card.

And for anyone else here is the F60 BIOS for the Gigabyte 280x Rev2 with 1.3v and The Stilt's memory timing adjustments:

Hello.

Thank you for your great work! This has helped a lot of people, including me.

Is it possible that you can implement my bios with The Stilt's memory timing adjustments aswell?
I have Gigabyte GV-R928XOC-3GD with Elpida memory.

Thank you in advance.

Should't it be .rom file instead of .F70 file?

Rename to .rom and will be fine.

Hi,

Like mentioned in previous posts i also have the R928XOC-3GD. JoeDirt was incredibly nice to adjust my bios to 1,3v but everytime we did that i was not able to start with the mini displayport adapter attached....

Can you tell me something about your Screen configuration....or better if you have a mini displayport connected and if it works with the modded bios....

cheers man,

Hey Joe, i have a little problem with my 280x, i've been using VBE7 to edit my voltage, i'm actually running 1160/1600 at 1.250V stable, but using trixxx i cant lower my voltage, i change the voltage, hit apply and on gpu-z the voltage stays at the value i've set editing the bios, so everytime i want to change my voltage i have to edit it on the damm bios.

And, adding more voltage does not seem to give me more space for clocks, even on 1.280V i cant set the core to 1170, which i think is weird, it should be able to handle much more on that voltage.

To lower your voltage what you have to do in VBE7 is lower you clocks and speed like this:



Now once you flash, you can raise your voltage to anywhere between 1.019v and 1.250v. If you want to raise to 1.300v then send me your BIOS and I'll mod that as needed.

Hope this helps you my friend!

What you will want to do now it flash it and then raise the clock speeds in TRIXX to what you want. Raise it to what you want then test. If it crashes then just start adding more voltage until it becomes stable.

I'm at 1100mhz @ 1.085v. Every card is different so just take your time and adjust as needed.
