RBE v1.27 released!

[BAGZZlash]

RBE v1.27 hit public!

• Added volt modding capability for CHL8214 voltage controller (reference design 6870 and 6850 cards).
• Added volt modding capability for VT1556M voltage controller (reference design 6970 and 6950 cards).
• Changing DeviceID now changes both locations properly (hopefully) all the time.
• Changing VendorID should work in more cases now.
• Added some new DeviceIDs (6950/6970).
• Updated WinFlash link.
• Updated RBE's internal BIOS extraction method to account for "ATI" labelled "AMD" now.
• Improved Hex editor interface a little.
• Fixed method 1 overdrive hacking signature extraction for 6xx0 cards. Only superficially tested due to no available non-reference signatures yet.

Have fun using it!

thanks for the continued support to a great tool

 

[Charly]

Tnx TPU guys, will test when I got my SB system, with cfx6950 .

 

[Boomstick777]

Thanks for this great app

tested it out but my HD 6970 is locking up at attempt to boot into windows if I change any clock settings in bios? Can you not alter clocks? Is this just for volt changing?

Exxxxcelllent!

I think this may have something to do with your issue:

I'm sorry I have to contradict: RBE v1.27 will (hopefully) support voltage control for 69x0 cards (among other things), but clock setting is still an issue because ATI introduced a new nagging BIOS clocking protection into their drivers.

 

[Boomstick777]

Seems I can only change voltage in RBE, if I change any other setting, clock speeds or ccc limit etc it results in a crash when PC attempts to boot into windows?

Anybody else tried this yet?

Set my voltage to 1.275 'no other settings changed' in RBE Flashed with this altered bios but voltage still showing as 1.175 in gpuz?

GPU-Z Doesn't read voltage from the card. It gets it's info from the driver. (On these cards at least)

Ok, thanks for that, yeah upping the voltage has given card more stability, just ran 3D mark 11 at max ccc 950/1450. It would crash at stock volts with 20%+ powerplay.

Just ran 950/1450 with 20%+ powerplay @ 1.25volts 'via RBE Bios Flash'
PII 1055t @ 3.6GHZ,

Totally stable got P5397 3DMarks!

Going to use afterburner next to get around ccc limits, see how far this card can go...

 

[BAGZZlash]

Thrilling stuff, I would love to see some nice overclocking results that have been made possible by RBE! Keep us updated!

Thanks very much for uploading.

So to edit my 6970, I just change the MV in the 4th tab ONLY (default 1175= 1.175v) to 1200 for a small vGPU increase to 1.2v?
(and also click on "set recommended fan speeds" for good measure)

Is this all that I have to do?

One suggestion: Put a big disclaimer into the first post that clock changes on 69xx don't work by BIOS. Apparently trying it prevents booting into Windows, which is annoying for people that don't know that this changed. (No need to open case and fiddle with switch.)

I'm going to undervolt 3D to 1,1V because my card ran 880 totally fine as a 6950.

 

[Murjuk]

Shouldn't these voltages be in increasing order?

No, the order is not important.

nice one man, ive had mine at 1010 core at crazy volts, 1.42 I think, it completed 3dmark 11 bench but Im not keeping it that way, I think 1.25 for a 24hr 950/1500 clock is really nice.

Try a value near 1.175V to use 950mHz. My card is stable @950mHz with 6970 3D voltage.

Same here - tried to up the OC limits to 1000/1600 but after flash only Blackscreen after Winlogo and Logosound was the result. Thought it was the driver, reinstalled it but with no success...

Seams that, as BAGZZlash already said, that the fu** ATI driver prevents this... What a pitty!

Took after this the stock XFX6970 bin and changed only the VGPU to 1220.
Thats more than enough for me! Otherwise it will be too loud under air

BIG THANKS GO OUT TO BAGZZlash & Wizzard!!!!

BTW, I couldn't make overdrive hacking method 1 with an 6850. Is there anyone could make it work?

Another report:

Subvendor ID changing works - tested from XFX to ATI
Device ID did not work: stays at 6719 (but 6970 selected -> 6718)

EDIT

Wanted to change 0900 VGPU for 2D to 0700 - But also: After reboot Blackscreen after Winlogo

Looks like that "only" 3D VGPU works properly - But nevertheless THATS MORE than enough at the moment

 

[davetheshrew]

why would we change the subvendor ID again?

I have changed 6850 2D and 3D voltage and it worked.

Device ID wouldn't work anyway. Because flashing a 6950 bios into a 6970 board and the device ID remains at 6719, when it should be 6718...

The question is, where is GPU-Z getting the device ID from, if BIOS changing isn't causing it to change?

I think GPU-z is getting device id from backup BIOS.

Um....no one answered my question O_O
It's register #4 for 3D GPU right?

Yes, it should be. Default 3D voltage is 1.175 so you should change that register.
