VBE7 - vBIOS Editor for Radeon HD 7000 series cards

[Timmen]

hey man can you please help me fix my card ? it has a busted temp sensor i want to default the fan from "auto" to a fixed %, say 30% because on every startup "auto" fan gets no reading from the busted temp sensor so it blasts the fan to 100% till i can apply my fan profile in trixx, couple of minutes of ear suffer on every startup !

can you please support setting a fixed fan speed value in vbe or help me edit my bios somehow

this thing is driving me crazy

i think your card gonna run hot if you fix the fanspeed constantly to 30% when playing a game or bench...

i would rather pick 60 to 70% to play safe, it def gonna make less noise than 100%

i already run both of my cards ( i have 2 cards only one of them got a bad temp sensor ) on fixed fan speeds , i have 2 profiles in sapphire trixx one for gaming and one for mining each of them got different clocks voltages and fan speeds

i hate auto fan anyways !!

i just want it to be defaulted at 30% to avoid the brief strong fan noise @ 100% on every start up before i could load up the profile i want from trixx , got it ?

can setting the fan speed to a fixed speed happen via hex editing or something ?

i will attach the bios here, could please someone hex edit the default fan setting to 30% for me please, i will be very thankful

Edit : by the way i just found out that my busted temp sensor card is in fact and engineering sample 7970 !!
i got that card cheaper from a guy here he didn't say it was an engineering sample , he said that it's temp sensor is not working and slashed it's price down a bit for me to buy it, could it be that AMD disabled the temp sensor in this engineering sample ?

anyways all i need is just someone who can hex edit my bios to default the fan speed from auto to a fixed value ...

You can have Trixx apply 1 of your profiles @ startup , that's the easy way .
the 'Startup' fan speed is tied to the boot clocks you could try setting them down but most likely won't work..... Fan speed could be part of the startup self test.
could you supply card [bios above] make & Mdl# or link to it's webpage

i tried setting trixx to apply fan profile on startup still takes a minute till everything loads and trixx loads the profile , and ofcourse my ears have to suffer in this minute ...

also there is no web page for the card, it's a reference HD 7970 GHz edition and as i found out it's an GHz edition reference engineering sample

the bios above did you check it ? can the fan be defaulted somehow from "auto" to "30%" ?

thanks !

 

[Blín D'ñero]

Try this. Your fan should start at 30% now, till 60 °C.
(I did not rename your file, so keep it in a seperate folder.)

thanks will try it and report back

but i have no temp sensor in my card, can you try an make it 30% fixed with no temp condition just a down right constant 30% by default and i will use trixx to make a fan profile with higher rpm if needed by gaming or mining...

Edit : tried it, didn't work ...

as i mentioned before i need the fan to have a fixed rpm regardless of temp, because i have no temp sensor in my card and this causes the card to blast 100% fan because it's getting no temp read on "auto"

also why i can't use vbe to modify my fan curve into a straight line ? the last point on the curve can't be moved down ...

is it doable in vbe to have a check box or something with set fixed fan speed option ?!

thanks !

can the fan be defaulted somehow from "auto" to "30%" ?

No such option at BIOS level. Anyway if your temp sensor does not work, the temperature based fan control won't work either.

can you take a look at the fan portion of my bios and see why it runs 100% on start up ?

i was really hoping for a bios level work around to my issue

anyways, thanks...

Hi again, gotta random question - how are you obtaining the part #'s on the IC's?

Cheers

Have to parse the vram info block. The part numbers are simply stored as text, the vendor names are based on the memory vendor IDs (for example 1 = Samsung, 2 = Infineon, 3 = Elpida etc...).

Nice work darkhmz, can you make it work with the R9 & R7 GPUs coming out next week?

Hi

answerer here

I don't know, time will tell.

I think the R9 290X will need the throttling 'feature' removed from its BIOS. Trying to get a headstart on that card so we can do some extreme benching on it when it's released. Hopin' darkmhz's program will work for it.

 

[Ja.KooLit]

have tried something.... just for fun.. never flashed though.. but only for trying...

I tried to open the leaked ASUS R9 280x with your .6 version...

it opens, seems to be like normal 7970 vbios..

Then I tried with your .7b version, suddenly it detects a UEFI image detected...

Gigabyte 7950 Rev 2.0

Hey guys. First time on this board. Mostly at Overclock.net and Tomshardware, but I need to broaden my OC experience for my GPU's and CPU.

I found this link from another post I was on about BIOS and volt locked GPUs. I am a noob to OCing, so first question, my card stock is 1000 core and 1250 memory and volt locked. I am using MSI Afterburner. I can get it to 1175 and 1425 at +20 power, but I see some getting better results. I have a crossfire set up and noticed on GPU-Z that I have two different BIOS for some reason as well as seeing that one card works more than the other (same exact cards, same model, make, brand). I bought them together. How do I get the BIOS for crossfire to become the same?

If I am messing with adjusting BIOS, should I flash a different BIOS for both all together? I have never done it before, but I have been doing some research. I know some BIOS dont allow use of HDMI, some have fans not working, etc....

Can you guys please help me out?

Hi

Welcome to TPU

How do I get the BIOS for crossfire to become the same?

Use the highest overclock from the vga card that dose not perform as well; forcing the card that dose not OC to a higher state will course instability.

If I am messing with adjusting BIOS, should I flash a different BIOS for both all together?

No; [this is not best practice]

I have never done it before

Gigabyte 7950 Rev 2.0 wtih 2 different BIOS

Here are my current BIOS:

015.026.000.000.000000
015.034.000.002.000000

I assume they should be the same, so which do I keep?

The first BIOS is my top card and the second is, well you guessed it, the bottom card. Thing is, I dont see anything for the second BIOS anywhere on Gigabyte or Tech website. Is this a new BIOS or something?

BTW the extreme overclock weblinks are bad. URL not found.

Hi

Here are my current BIOS:

015.026.000.000.000000
015.034.000.002.000000

I assume they should be the same, so which do I keep?

Even though the HD 7950's are the same make and model rev 2; it is not safe to assume that they have the same components @ PSB level as Gigabyte *may have made small changes to components due to supply and demand.

Make a backup of both vbios images and edit copies of them separately [DO NOT MIX THEM UP]{or} attempt to flash the vbios image for the Top vga card to the second card or vice versa as this may cause either vga card to function in a way unintended by the manufacturer.

As far as i know GB 7950 rev 2-s are voltage locked. One of my friends was just looking for a second card for CF and avoided rev 2-s for this very reason. Also rev 1-s are more expensive in aftermarket because they're good cards OC wise and unlocked.

Yeah its because VBE7 scans for the UEFI image after the legacy image, and previous versions assumed that the legacy image size is always 64k, which is wrong. Fixed it in .7b, now VBE7 detects the image size.

Hello darkhmz,

First thanks for this excellent program!
But I have a problem, hope you to me will help!
I have 7970 ASUS DC2. With VBE7 I can't change voltage. By default mine voltage 1.100v,but VBE7 shows 1.170.
I would like to raise to 1.200v.
Thanks.

That means that the voltage is either hardware locked or you have some bad vdroop. Looking into your BIOS now.

Ok, I raised your TDP a little bit and increased the core voltage from a setting of 1.170 to 1.237. If you're hardware-locked, there will be no change in your voltage. If BIOS editing your voltage works and you just have bad vdroop, it should now be ~1.16V on the core.

 

[neklec]

Random Murderer thanks you,
I will try.
I can change voltage if flash with vbios DC2T, but productivity is worse then. For this reason I want mod the vbios DC2.

Yeah, get back to me and let me know how it works. Chances are, if the voltage adjustment works, you'll want to set the clock speeds and fan profile a bit differently. If that's the case, I have no problem taking a few minutes and taking care of that for you.
