Graphics ati 6950 to 6970 bios

Hi i'm looking for a bit of help i have bios flashed my 6950 to 6970 but i'm not happy with my voltage and i know it will run the clocks i want on lower so i was wondering if anyone has or knows how to mod the bios so i can drop the voltage i have the RBE bios editor but i'm not the confident about changing it my self

I have tried msi afterburner but can't get it right and my screen flickers

I have a HIS 6950 flashed with the sapphire 6970 bios

Any help would be cool

 

Send me your Bios, and I will sort it. Need to know what voltages you need.

 

Thanks i will send it you when i get home from work

 

I'll probably be at work then... (Work nights...)

I'll try a bios off of techpowerup - But they are usually dodgy...

What clocks and voltages do you want?

 

Hi mate just got back from work do u still want me to send you my bios ?

As for voltage and clocks

with 2d clocks still on

Core 800/1000
Mem 1375/1500
Voltage 1100 instead of 1150

 

I mite add techpowerup is were i got the bios from lol i got a sapphire one if that helps

 

If you post me the link to that bios that you have already tried and tested. Then I will have a look first thing in the morning.

Have a read through my thread to explain what you will need to do, as using different voltages on the card will not correspond to the driver voltages. So you will need to clear all display drivers.

No haven't read it will have a look thanks heres the bios link

Thanks for the help

 

The linked Bios is pre OC at 880MHz Core - Are you sure it will run at 1.100v instead of the 1.175v?

Try it and see for yourself - But please read through the linked page, and read all of the first 2 posts, so you understand the whole process, before flashing your card with this tweaked bios.

HD6970 Bios 1.100v

In pure dos type this command: atiflash -p 0 6970.AC1 -f

 

Stupid double post...

 

Hi mate Thanks for the help and info in the post as for the pre OC bios yes i think it should run ok i mainly wanted it modded for the unlocked clocks the lower voltage is to keep my temps down a bit

Before i had it stable at 920/1425 1.100v but it didn't like being under volted with afterburner.

Just a quick question before i go and flash this why is the file .AC1 ? also it won't show up in RBE editor ?

 

.AC1 is what Sapphire use for their vbios extension.

This is why you can't see it.



Have a play and report back, I'm here till 10am then i'm off.

 

Hi mate everything is running fine just had a quick run on 3dmark 11 at 880/1375 1.100v no flicker temps didn't go above 62c and for some reason i got a better score lol 5996 but i will keep my eye on things and give it a good run today to make sure it's stable.

All i need now is a better cooler then i can start playing around with it a bit more

Thanks for all your help

 

Great stuff. If you want a higher clock I can do that on both the memory and Core.

 

Hi mate i'm ok at the minute with this bios it's spot on thanks i was playing most of yesterday with no problems what so ever temp didn't go above 65c and all my games running butter smooth

Thanks again for the help
