AMD Radeon HD 6950 Can be Unlocked to HD 6970

[MarcusTaz]

In 3dmark vantage i got 19776 points with 6950 stock speed,changed bios to 6970 stock and got 19001 points with 0% on power control and 19083 with power control on 20%

Hope I do not run into this problem...

the thing is not all 6950 cards can perform up to 6970 standards, the fact that the majority seem to do well is just good luck for us end users

Is the artifacting in AtiTool a pretty much universal problem? It seems like most if not all people that have run it at XS have had artifacting that they didn't have with the stock 6950 bios. I don't see the artifacts if I use the older scaning method or lower the core clock to like 500. I've heard similar reports with 6870 although it worked fine for me. If anyone has a real 6970 Sapphire and wants to run ATITool that would be great. The artifacting that I saw with Super Meat Boy is also far worse than I saw with the stock bios and my 6870. Gpu Tool, OCCT, and other games seem to be fine though.

well I hope I get lucky... Just ordered an XFX 6950...

It could be a number of things....... is it the same rated memory on both models, is it the same rated memory voltage and GPU 3D voltage in each of the Bioses, it may be something as simple as loostening memory timings or lowering memory clocks or just increasing the GPU voltage a little, although it sounds to me that some are getting memory throttling which could cause the slowdowns described.

i did a 20minute run with occt when the card was first installed. 82c load fan at 36% (???) no artifacts , i did go to install ati tray tools but it made my system bluescreen on startup which i have never seen my system do ever except for when my memory went faulty.

ok thought i would test ATi tool, very strange i have the real HIS HD6970. if i run scan for artifacts strange lines etc straight away. i think this is a problem with ati tool and not the cards. ive run this afew times i let the card heat up with 3D view then scanned. i also let the card cool down and run again.

looks perfect on 3D View.

scanning for artifacts straight away (hot or cold)

like i said i really dont think this is a problem with the cards but a compatible problem. as you can see no errors are reported, ati tool gives off a bing every few seconds.

 

[BababooeyHTJ]

Thank you, I've been hoping that someone with a real 6970 would run AtiTool.

My friend unlocked his but had to drop the clock speeds. Hopefully that afterburner beta comes soon. Don't know if unwinder even got the card yet.

No, what i was saying is that the extra cost mean faster rated memory chips, if the difference between memory rated for 5GHz and 6GHz and a couple 12v ground wires means nothing to you then that's fair enough but there has been many cards over the years that have been able to be hard or soft modded into the higher end version and as with all of those even if the success rate is high it does not guarantee that it will work, the same applies to core unlocking on CPU's and also overclocking.

Personally i like the idea of paying a little more and getting a guarantee that it will work at 6970 speeds along with the extra pair of ground wires and memory rated to run 1GHz faster effective, if you think those things mean it's a rip off that's your opinion but it's not as if they are the exact same cards with a price difference as there are things that make the 6970 better than the 6950.

What would make you more unhappy, knowing its possible to take the 6950 and flash it so then buying one that was not stable after being flashed or buying a 6970 and knowing it will be 100% stable and the fact you paid a little more for that guarantee and higher binned chips?

little more? $100 pre card!! thats %33 more.
the unstable rate is 2 out of 140 and i'm sure not everyone that it work for would have emailed.
now i find out that the components used on my card are left over junk amd had from 5000 series.
MAKE IT STOP!! PLEASE MAKE IT STOP!!

left over junk???

Ignore him and let him troll the other thread. This one actually has some good info in it like your Atitool post.

 

[erocker]

ATi tool doesn't support the 5 and 6 series, of course it's screwing up. Hopefully you aren't ruining your card running it.

 

[DigitalUK]

no im not running it but it looks like some are using ati tool as a proof of stabilty in these cards, just wanted to show it wasnt.

Volterra digital PWM were used in 5800 and 5900 series. so yeah left over junk

I got the black PCB Sapphire. Flashed and seems to be working great. Running cool, too. Much cooler than what the reviews were showing.

Nvm, powertune isn't in the 10.12a drivers...

Just using it to scan for artifacts?

If they are the same vrms as the 5xxx series where are the readings in gpu-z?

The Radeon HD 6900 Series are the first graphics cards to use the Volterra VT1556. It offers extensive voltage control and monitoring via I2C. At this time no software supports this controller yet, but I am sure this will change in the weeks to come.

Go troll somewhere else.

i take that back. slightly new junk then that which was used in the 5xxx series.
i did say "Volterra digital PWM" i didnt give out a model number. we still didnt get the top shelf gear

What testing have you done to back those statements up? It just goes to show that you have no clue what you are talking about. ATI is switching over to the TI vrms because they are cheaper not better. Although if these vrms run as hot as the old volterras I'll be a little disappointed. I doubt that they will but we'll see.

 

[DigitalUK]

its not junk its exspensive, they want a cheaper way and probably more to the truth stop the 6950 to 6970 modding.

AMD the opportunity to redesign the PCB to make use of the more cost-effective yet high-performance VRM circuitry

your point being, it doesnt say the current PMW is not high performance, its to reasure future customers that even tho the cards are cheaper(using cheaper components) you wont lose out on performance. the current PMW is fully adjustable by software as soon as software is realeased to support them.

 

[LAN_deRf_HA]

For my friend's flash I just swapped the "unlock" file with a renamed asus bios and ran the batch file. Gpuz says it worked, but smart doctor complained about not being able to find the card or something. All we did was restart the pc twice to let the drivers sort themselves out. Is there anything wrong with flashing it like that and or do you need to completely uninstall the drivers?

if amd were willing to delay and almost miss out on xmas shop period for the DrMos then im sure that its better.

Question....

If I don't buy another 6950/70 before they change the VRM stuff, would I be able to successfully change the voltage on xfire'd cards?
