Unlock your ATI 6950 to a 6970 Thread

Flashed my HIS that I purchased on Xmas day, been gaming for days at stock 6970 speeds with no issues at all.
I used the batch file method and kept same drivers as im lazy :)

I have read that the Asus Bios has a higher voltage for the 6790 than other bios's.

Does the 6850 bios (which I have run the script to unlock it) have a higher voltage to other bios's?
Also does Asus Smartdoctor only work with Asus products? (I realise this is a somewhat nubby question but I have the 6850 modded bios running and don't want to perform another flash when it really is not required).
 
Asus Smartdoctor only work with Asus bios's

Asus Bios as the same voltage has other bios's.

for 6950 it's 1.1v , for 6970 it's 1.175v

Its sort of an unlock to a 6970, the texture units on the board according to rage 3d don't get unlocked so more like 99% 6970.

Though it was that but turns out it isn't.

Just looking through some other threads and had a thought....

Turns out it is the smooth scrolling option in IE.

ah right , well i dont use IE so thats probably why i dont suffer the issue :)
 
what you you guys using to volt change the 6950 ?
i need to pump some more volts on both of mine ( 6950's )
 
if you flash with the Asus BIOS, you can use their OC tool that supports voltage mods. Reading other forums, I believe this to be the only way via realtime software at them mo.

For those who are interested, I'm working on a veriant of w1zzards (Techpowerup) modded BIOS - unlocks the cores but changes nothing else.

I hope it will increases FAN speed across the whole heat range and change the default clocks to 880, 1375. I know that most cards work at the box with stock 6970's bios but some have reported problems with ram timings being too tight.

These are the changes listed below:

Core: 880
Mem: 1375
3d profile volts: 1.175
Customer fan map

GJ02 - it's possible to change the core volts via this method - look for the following app on the techpower web site RBE_126.exe but remember this will pump the volts you set on card boot so take it easy if you chose to go this way.

edit - volts can been changed within the new bios file but don't seem to work. Thanks to mglover for pointing it out and making me test :)

You are spot on the monet about the ram timings.
The program your post speaks of says the following in the release notes for version 1.26v:

•Added (preliminary) support for Radeon HD 6850 and 6870. Everything _should_ work, except for voltage modding.
•Fixed minor WinFlash version detection bug.
•Improved built-in hex editor search functionality (again).
•Improved flashing procedure for more stability.
•Fixed Dell Subvendor-ID, thanks to Clinton for the tip!

The voltage modification doesn't work :p. Once this does work it will be brilliant though! I might try and make myself a 6950 (with extra shaders of course) with 900mhz core at the stock 1.1v.

EDIT: It is not for the 69xx series, but I had a nosey anyway!

thanks mate ;)
i will wait for afterburner i think
 
Hmmm with the bios editor program there are several clock modes. I have the Asus 6950 bios with unlocked shaders on my HIS 6950 (not that it being HIS makes any difference!).

Clockstate 0 is boot - Stock 6950 clocks, OK I get that
Clockstate 1 is for laptops - O250mhz core, OK I get that
Clockstate 2 is for videos - 500mhz core, OK I get that
Clockstate 3 is unknown - 810mhz core. Clearly this is the Asus bios setting that I have installed. Does this core speed get upped when I reach windows or something?
Clockstate 4 - 725mhz core but there is nothing listed to what it is. Wierd.

All have 1250mhz memory except for Clockstate 1 which is 150mhz (yes 150, I didn't miss a zero off the end:p).

Vendor preset OC?? it's my only guess right now.

Having said that, when you save the bios file this value is reported in the file name as the 3d clocks.

mg - did you use the Asus 6970 bios?

I have used many different ones. I am currently using the Asus 6950 one with unlocked shaders as the 6970 one sometimes (and I mean it happened only once) I got green lines all over the screen when the power was at +20%. I am 99% sure that was down to the memory timings not being correct.
 
Going back to the volts.

Just read the FAQ for bios creator/moddifier. It states:

Q: Why do I get three dashes instead of a number in some of the 'voltage' boxes?
A: Those voltages are 'fused', as ATI calls it. I suppose this means that it's the driver that sets these voltages. However, you can just leave this as it is or you can overwrite the dashes with any numeric value you like.

So, this must mean that the drivers decide how much volts to supply to a card via the bios string. So it is possible to up the volts.

1) Change the string of a 6950's bios to match that of a 6970 - so 1.175v (not much I know).

Or

2) Within a DLL there must be a line that states what volts can and will be supplied to a card with X bios string. Find that and change the volt value.

Option 2 would be a little dodgy and the inherant risks would be huge.

Edit:

Guys, I wouldn't recommend any of these options and would ask that you do not try it (leave that to me :)). Far better to wait for afterburner support.
