@Chispy

How many volts did u use with smartdoctor?
With 1.35V I get 1075 on core, higher voltage doesn't help.

I was using 1.42v for 1083/1527 , more volts did not help thats my card limit max on water , maybe will go higher on LN2

Windows 7 x64

Good news are coming.
RBE v1.27 lets you edit the voltages freely.

It should be higher with LN2 Did u use v-mem mod?

[chispy]

Yes will go higher on LN2 but i believe this cards will max out ~1150Mhz as the circuitry its a cut down version of the HD6970 and cannot handle much more , no v-mem mod yet but i was running the card on my water chiller at -12c , but i added a whole bunch of all cooper small Enzotech heatsinks to the VRMS area and a couple of mosfets , also i added all cooper big chunky swiftech Memory heatsinks to the memory and i believe that helped me a lot. Not bad for a card i paid $279US Dollars at newegg .

I'll get 6950 after week
Looking forward to flash

[ElBobbo]

What do you guys think about running two flashed 6950s as 6970s in XF on a Corsair 620HX? I'm going to have to use two molex->pcie cables as it only comes with two 6/8 pin sockets to start with.

Bad idea. Get a stronger PSU.

Woooooooooooooooooooooot. After a few dungeons I will give this a go.

Edit does GPUz still not reflect changes in voltage?

Blamo, that's what I was waiting for!

Cards are now under EK 6970 blocks and my 2500K is approaching 5Ghz stable. Time to GAME!

Sweet! Thank you!
Interesting note:

Note for those who use modded 6950 cards. Afterburner provides voltage control only on reference design 6950 cards with 100% original 6950 BIOS and 6970 cars with 100% original 6970 BIOS. Afterburner's voltage control WILL NOT function if 6970 BIOS is flashed on 6950, it is supposed to be that way and it won't change in future versions and any "bugreports" on it or demands to "fix" it will be ignored.

Edit1: the file doesn't work, the file name is "MSIAfterburnerSetup210Beta6-[Guru3D.com" for some reason, wth.
Edit2: don't use European mirror. It has issues.

Really glad to see thinking users in the forum. Yes, it is possible to override the database to make Afterburner voltage control working with 6950 flashed with 6970 BIOS. 6970 voltage calbiration info should be added to 6950 configuration file in this case:

VDDC_VT1556_Defaults = 9A 5C 9B 80

^ Later in the thread

Anyone know where this 6950 configuration file can be located ? I must be brain dead today..

MSI Afterburner/profiles

I have 2 cards so I did to configs.

File name may look like this
VEN_1002&DEV_6719&SUBSYS_0B001002&REV_00&BUS_2&DEV _0&FN_0.cfg

Add this to the end after the profile info

[Settings]
VDDC_VT1556_Defaults = 9A 5C 9B 80 <---- what i used


I have a set of Sapphire HD6950 flashed to Sapphire HD6970

I ran a quick test during lunch to make sure it worked at 1000/1450 @ 1.30v
It did Vantage fine. GPUZ still reads voltage at 1.175. My cards would not go past 945/1450 @ 1.175

Have you or anyone else tried this on a 6950 that has shaders unlocked but nothing else? I'm using Wizard's tool so its not a full flash to 6970.

I haven't. Just with the 6970 bios.

not a bad loop, but I would do CPU->RAD->GPU's->RAD->PUMP

that would see you getting better thermal performance
