VBE7 - vBIOS Editor for Radeon HD 7000 series cards

[aaronsta1]

i can not believe i have to make an account for this BUT: where do you put the .fpr file?

YES i did google it, yes i did a search on this thread and YUP i even asked on IRC. also the file i made is the only one found on my computer.

please add this info somewhere....

EDIT: have you ever tried to google "fan profile"?

its just the fan profile, save it anywhere you want.. i put it on the usb boot drive i use to flash the gpu rom.

its not part of the program or the rom, its just something you can save so if you change the fan profile you can load it back up again.

You dont have to "place it" anywhere. You have to load it trough VBE7 interface wich imports it (Fan Profile > Load).

Btw im not sure if you're from the same country as me but that username...lol

So I'm working on overclocking my cards and I noticed that when I disable the compatibility module (which deals with legacy hardware).... this effectively runs in FULL UEFI mode....

When I do this, my card's voltage does not waver away from 1.09v, not idle, not under load, nothing. I can't even change it using software like sapphire trixx. The clocks do change based on load, it's just that the voltage is fixed.

When I turn the compatibility module back on, and boot in UEFI mode (or even not in UEFI mode) then the voltages will go up and down based on load.

Is this normal behavior? Why is this happening? Can I get my card to regulate voltage again? Can I at least set it at a fixed 1.3v so i can overclock?

Which bios setting do i alter to change the fixed voltage?

Very old thread but hopefully someone can help me. I've been having an issue that my gigabyte 7970Ghz clock speeds are downclocking from boost speed whilst ingame and hurting my fps even though my temps are not reaching 80c. So clocks will go down from 1100Mhz to 1050Mhz. Not sure why this drop of 50Mhz makes such a difference ingame but for some reason it does.

So I followed the procedure of changing bios clocks and I changed #6 from 1050 to 1100 like this:

It seemed all was good initially but now after a longer time ingame the clocks will suddenly drop to 1000Mhz, and there it will stay with the only way to get it back to 1100, by rebooting. I'm unclear how it can even get to 1000 when it's not even an option. Any idea what to do? I have attached my modded bios.

I assume you are in legacy mode? I only ask because the modifications you make using this software will only effect the legacy Bios, NOT the UEFI, if you are using legacy then I cannot explain why the issue began initially however it sounds to me that the problem may be powertune, you may be able to increase the TDP levels in powertune on the 3rd tab of VBE7 which should then give you the option to increase it within CCC, with the increases you have set you could be hitting your current TDP max causing the downclock.

 

[Jynn]

Sorry but I don't know what legacy or UEFI mode is, where would I find this out please?

 

[Jynn]

ok I think I found the problem. I forgot to look in the other states and in UVD mode found this:

SO it seems to be going into UVD mode at some point and never going back to max clock speed. What is UVD and is it safe to also change this to 1100 so it never downclocks when ingame? (Still would like to hear how I find out if I'm legacy mode or not).

UVD is AMD's GPU accelerated video decoding mode. It's used when watching Blu-Ray etc.

So No, you can but don't really want to set UVD mode to full 3D clocks.
Since the introduction of Windows 8, Bioses have included a UEFI mode which is basically a different and more visual Bios interface, Legacy mode is what you would normally get prior to that when you went into a Graphics Card or Motherboard Bios, so all Graphics Bioses now have 2 (in effect), if you use this software in only changes the legacy bios.

I still think your issue may be associated to Powertune in relation to downclocking if heat is not an issue.

 

[Jynn]

I did up the tdp wattage from 220 to 265 in powertune but did not tick the 'manual power limit adjustment' box. Do I need to tick that?

Yes I think so, I seem to recall that without it the higher limits would not stick in CCC.

good

 

[Jynn]

Thanks for the help so far Tatty_one, recently it has stopped downclocking to 1000Mhz for a reason I don't know, so I will just leave it for now and try reflash if the problem comes up again.

Does this work with the 270X? or any R9 200 series cards?

I think the answer to that is yes if they are Hawaii, don't think it works for Tonga etc.

 

[nidzakv]

Can i safely set minimum fan speed to 20% or lower, my MSI 7970 lightning is a bit noisy at idle?
I never done this with ati cards, nv only with no problems. This have some complicated "uefi legacy" bla bla bios.. So just extract, modify, flash?

Thanks in advance...

 

[Tatty_Two]

In theory yes, there is always a risk with flashing, if your happy that 20% will keep the GPU temps low enough in low load situations. Be aware that if you do flash you will loose the UEFI Bios and default to legacy if my memory serves me correctly......... well it did with my 280X.

Why do i need Uefi bios on gpu? Whats wrong with the "ordinary" gpu bios? And is there some nice atiflash tutorial? its a bit more complicated than the nvflash...

 

[jboydgolfer]

if you flash the GPU , you wont have a uefi bios any longer afaik. and as far as steps to flash, its very easy. Save the original with GPUz. then Run the bios editor(as admin), load the bios image you want to modify, do what you wanna do, save it. Then run Atiwinflash,(as Admin), then load the saved image from earlier that you modified, hit "program", then restart PC.

i cant stress this part enough. be sure to SAVE an original bios version, and in my experience, its Best to Expect the worse, and HOPE for the best..but always plan accordingly
do you have a back-up gpu (that you could install in case of a brick)? or a dual bios? or some other type of Plan "B" ? if no to any of the above, id reconsider.

 

[nidzakv]

It doesn work.. Stays at 25% and 1100rpm..

1. gpu-z saved bios
2. Edited fan profile min 20% untill gpu reach 50c..
3. Saved as new.rom
4. copy atiwinflash folder to c:\
5. paste new.rom in #4 folder
6. shift + rightclick in atiwinflash run cmd from this location
atiwinflash -f -p 0 new.rom ----> enter

wait a minute, says all god, but when i reboot fan minimum is still 25% and 1090-1100rpm...

Am i doing something wrong?





EDIT

I think that, maybe fans physically can go under 1100rpm.. Thas the only logical explaination...

 

[Tatty_Two]

If it's a hardware limitation then the flash will not hold but I find it strange that it can't be programmed lower.

 

[nidzakv]

So?

Maybe i should try with atiflash instead of atiwinflash?

 

[Tatty_Two]

I always flash from Windows, it's so much simpler, no command lines to worry about just click and go......... some don't like it, don't know why, I have been doing it for 10 years and never had any issues, at the end of the day whichever way, a flash is a flash so if it didn't work with one method it won't work with the other.

if you want to upload your modded Bios here as a zip file I will take a look at it when I am home after work but you sound as though you know what your doing so I doubt you have missed anything within VBE7.

 

[nidzakv]

Ok, i will.. Im not at home right now. Ofc i know, but i think im missing something..
When i load default .rom to vbe7, in fan profile minimum is set at 30%.. Actualy it is 25...

 

[Frogger]

Load up afterburner &see if you can set the fan below 1100 rpm. Then you will know if is a hardware limit
