The bullet has been bitten [2nd 6950]

Not entirely sure why that is, I'd try using afterburner with unofficial overclocking. I haven't actually heard of your problem, what brand of card are you using?

Right flashed to unlocked asus bios from the zip you gave me, but smartdoctor doesn't unlock the higher clocks for me. I followed the instructions to the letter. After uninstall of smartdoctor and launching ccc, top clock available is 840. Any ideas as to why the limit is not higher? I have had Afterburner 7.2 beta installed from before I did the unlock 50 bios flash. I don't know if this has anything to do with the problem.

did you enable overclocking range enhancement ? before uninstalling ?
 
My card has arrived but I can't see the warranty registration details? or is it software based?
I also would like to clarify what to do regarding flashing?

Modified 6950 bios or a particular 6970 bios?

Thanks guys
 
I can't see any reason not to use atiwinflash - it works, and in the unlikely event your PC happens to crash in the few seconds it takes to write the bios, you have a second bios. :)
 
I'm still old school with the BIOS flashing. But yes, with the dual BIOS winflash is safe enough. I am just not familiar with it as I never use it.

I know you have a 6950 winflash guide around somewhere, why don't you post that here for those more comfortable with using it.




EDIT: Found MikeHiow's winflash guide. ^

Ok maybe it's because I'm new to this but this seems more confusing to me

Should I go back and reflash my first card too?
I'd be more comfortable with just flashing to the 6970 bios as I know what I'm doing

Is the 6970 bios that bad that it's not a good idea to do it?

I would not use a 70 BIOS. So yes, I would put a 50 BIOS on you first card too.

is this a widely regarded opinion? obviously each flash holds a risk and worst case i could bork both cards [unlikely but possible] also i had big issues getting the first card to flash
 
It is to all except those that are running 70 BIOS. There are many 50 cards out there that were permanently damaged by 70 BIOS's.

If you read the threads associated with those two links I posted, mine and MikeHiow's, you will see the reasons why it is a bad idea to run 70 BIOS.

BIOS flashing is very easy and only takes 2~3 min when you know what you are doing. MikeHiow's guide is pretty much step by step.
 
Yep i read about the ram sensitivity, i guess ill have to wait till the weekend to do this, as i will probably have to do each card individually

ill do some more reading, its to expensive to make the wrong choice with something like this
 
You can flash both cards, with both cards installed:

atiwinflash -p 0 uppercard.bin
atiwinflash -p 1 lowercard.bin
or
atiwinflash -pa flashesallcardsatoncewiththesamebios.bin


Edited MikeHiow's post to suit your setup with both cards installed - Edited bits in red:




Card 1 - Upper Card - your New Card:


Ensure your BIOS switch is in position 1 before anything else.

Avoid the 6970 Bios. What you want to do is modify your own BIOS to unlock the extra shaders.

First you'll need GPU-Z and this: http://www.techpowerup.com/wizzard/Mod_BIOS_HD_6950.zip

First you need to dump your BIOS in GPU-Z - there is a little icon next to the bios version, click this to save your bios.

Extract the 'Mod_BIOS_HD_6950.zip', put your bios in that folder and rename it to 'original.bin'. Run the run.bat, follow the instructions and you will end up with another file called 'modded.bin'.

Now download an extract this: http://uk2-dl.techpowerup.com/Tweaki...D_6970_mod.zip

Ignore all the bat files, all you want is winflash. So copy the winflash directory somewhere easy, I'll use c:\ as an example. Also place the 'modded.bin' you generated in the previous step in the winflash directory.

Now open up command prompt as administrator, and type 'cd \winflash'.

Now you want to do;
atiwinflash -unlockrom 0 (THIS IS A ZERO not an O)
atiwinflash -f -p 0 modded.bin

Follow any instructions and reboot when it's done.

Once complete you should have 1536 shaders (you can check this in GPU-Z).

Just note that you do all this entirely at your own risk. That said, if you run in to problems, you should be able to just flick the switch back to position 2, and you're all good.




Card 2 - Lower Card - currect card w 70 BIOS:


Insure your BIOS switch is in position 2 before anything else.

Avoid the 6970 Bios. What you want to do is modify your own BIOS to unlock the extra shaders.

First you'll need GPU-Z and this: http://www.techpowerup.com/wizzard/Mod_BIOS_HD_6950.zip

First you need to dump your BIOS in GPU-Z - there is a little icon next to the bios version, click this to save your bios.

Now open up command prompt as administrator, and type 'cd \winflash'.

Now you want to do;
atiwinflash -unlockrom 1 (THIS STEP NOT NEEDED on CARD 2)
atiwinflash -f -p 1 modded.bin

Follow any instructions and reboot when it's done.

Once complete you should have 1536 shaders (you can check this in GPU-Z).

Just note that you do all this entirely at your own risk. That said, if you run in to problems, you should be able to just flick the switch back to position 2, and you're all good.

It's a HIS, Afterburner was already installed prior to the flash, but if you go past 840 in afterburner, then ccc starts flickering. I was just after the 880 clock of the 70 bios. Ideal for me was 880 on the core with 1300 on the memory.
Wasn't wanting to depend on afterburner to achieve the speeds i was looking for.

Yes, i got a flickering black screen when it was applied, so I presumed it was doing something.
I followed all the instructions to the letter but no joy with the extra ccc clocks for me.

It's not as if it's a poor clocking card either as after the flash the card can do a 25% overclock:
Amd 6950 2Gig With Shaders Unlocked
1ghz Core(Stock 800Mhz)
Memory 1.3Ghz(Stock 1.25Ghz)
1.265V (Stock 1.1V)
Kombuster Run MAX temps 50c
Cooled By Modded Arctic Cooling Accelero Xtreme 5870 VGA Cooler

5 min video (pretty boring but you can skip to the end to see that it's stable)

Bing ;)

A whole unlock thingy with the ASUS bios, gives you extra voltage for free, a tiny OC and unlocked shaders. Perfect?

And it's no worries, happy to help :)

If you do decide to reflash your 1st card, shaypers link and instructions are very clear and pretty much just as easy.

I will attempt this at the weekend, also the older card will be in the second position as it has a better warranty and will be the hottest card so ill probably just do one at a time.

I'll also use winflash and probably flash both to 6950 bios unlock

Will I need to use one of the over volting tools with this as with the 6970 bios I've just been using ccc power tune
 
I have fixed above for new card on top.

Yes, you'll need to set V to 1.175 to be same V as 6970 BIOS. Or just leave at stock 1.1V and see how high you can clock from there. I use AfterBurner for V, OC, and fan control. You can also set V in BIOS with RBE.


As far as using AB see here:

Single post but you should read the whole thread.

This may be of interest to you, al4x(and any other 6970<50 downgraders) and save you loads of head scratching;) as you are going to flash from 70<50 unlocked shaders too (in your case I would downgrade your 70<50 unlocked shaders before installing the second 6950 for flashing)

After trying a few things with no luck here's what I did:

***This was done using Shayper's method he gave me here: Post 15***

Before you flash the card go here:
http://www.sevenforums.com/tutorials/77614-device-manager-hidden-devices.html
Follow the instructions and go to computer management>device manager. You should have two 69 series drivers (the shaded one is the 'old' original 6950 driver) but only get rid of your 69series ghost driver. If like me you may have other display drivers you need to get rid of them too. I had my old ghost 58series driver, nvidia(for hybrid physx)and logmein. I uninstalled logmein from the control panel but you then have to also uninstall it in the computer management>device manager too.

You should now only have the one 69series showing.

Now go ahead and flash to downgrade your 70<50 unlocked shaders as per shaypers instructions but don't reboot yet at step 12, when the window asking to reboot appears.

Before you reboot, uninstall the remaining 69series (6970) driver in the computer management>device manager (which will leave you with no display drivers installed). Continue from step 12b.

At step 19. Wait for your pc to install the generic 6950 driver before you reinstall 11.2 drivers(if it doesn't install the generic driver don't worry).

Then carry on from there.

At step 26. when you uninstall Asus SmartDoctor, you should get the option 'Keep clock and voltage setting when closed?' click yes and it's all good!;)
