RBE v1.27 released!

[davetheshrew]

any report/confirmation/denial about voltage of the GPU and memory being connected?

I deny it, why would asus make software to kill/set fire to cards?

 

[vvulture]

I am also reporting my confirmation of denial.. there would be no sense in tying gpu and ram voltages together.

Did several test to add voltage on my unlocked 6950 to 6970 (cfx) but it doesn't work.
With every 3d app. it hangs or resets the driver.
I did shut down the pc after a voltage flash and ofcourse flash both cards with winflash.

Also test with a 6950 bios ,but also the same.

I'm just waiting for msi ab. to work with crossfire.

At what % do you set the fan? Fan and temp are very important if you clock or volt your card...

Try to set fan @ 60% fixed and see if this help....

 

[Falkentyne]

Has nothing to do with fan speeds.
The 3d aps wont even start.
I know what bug hes talking about.

The SAME bug happens with smartdoctor....I saw people posting about it...

Hmm I can't, using a waterblock

Even @ stock speeds it freezes, every bios with voltchange it just hangs in 3d.
Flashed it back without voltage change and everything is ok.

I had that happen 1 time, I reinstalled driver. put second card in, ran the install again and rebooted, worked fine after that.

also look in GPU-Z if you see 768 shaders and 4 ROPS then the driver didn't take.

just a note, only change volts in GPU register, do not try to cahnge it in the Power play states drop downs.

 

[Charly]

Please post a screenshot with >1000core with cfx and kombuster running

I just change the #3 and #4, also #4 only.

Can't seem to adjust voltages properly on my 6850, whenever I changed them to anything, in any phase, the ATI driver won't load properly (CCC just says no ATI card is installed, device manager shows "device is having problems" for the ati 6800 series)

Currently flashed with a 6870 bios to get the increased overdrive range while retaining 2D clock/voltage throttling. The increase of voltage from 1.15v of the 6850 bios to the 6870's 1.175v doesn't help my core overclock by even 5mhz, it just adds power drain/heat/noise, so I want to set it back to 1.15v.

wow! is everything stable after flashing 6850 with 6870 bios? i have an xfx 6850 (reference), so does it mean i can flash it with any 6870 reference bios getting it's clocks/voltages and CCC overdrive limit? i've always thought that the card won't boot after flashing 6850@6870.

Yes you can but first try if 6870 voltage and gpu/mem clocks are stable. You can try trixx or after burner programs to overclock. After that try flashing with "atiwinflash.exe -fs -p 0 6870bios.bin" command. After flashing new BIOS, check for stability again.

I've already checked it for max OC and it's working stable at 950MHZ@1.262V/1100MHZ (tested for about 30 minutes in OCCT :] ). Max memory overclock is dissapointing. Even at 1150MHz without GPU OC at all my card hangs in 3D :/

well, thx for info, gonna flash some 6870 bios too

 

[2wicked]

Flashing a hd 6850 with a 6870 bios may cause the hdmi and display ports not to work.

 

[Martin von R]

If you flash to a HD6870 from a 6850 bios look here

[bonzai_cyberninja]

Im wondering why it could be that everytime i make even the slightest modification to my 6870 bios in rbe and then flash it, it seems to work, but then when i reboot into windows, catalyst doesnt recognise anything. So i can flash, but it fails as i cant do anything.

Any ideas???

 

[Martin von R]

yes it is a bios set more you ned,look in the link/foto

 

[bonzai_cyberninja]

ah kk, i got it to work now. now time to see how hard it can go. so far 1050 on gpu and 1225 mem.

Dont suppose anyone knows of the max memory speed the 6870 can obtain is?

 

[Martin von R]

I have a XSPC chipset blok on gpu ?
whit air is load temp 82/82c max oc 1100/1245
an whit water it is 42/45c
but it gives no room for more oc with water on only one doing temp, have tried up to 1.5v, which is something that stops me at 1110 on gpuen but do not know what it is

 

[Martin von R]

It can be VTT but not in rbetool for HD6870, it was otherwise well with my overclock on my HD4890

 

[Goodman]

Just stop here saying Thanks! & keep up to good work

 

[Martin von R]

yes it is yummy some will spend time on us
and so we require just into

ah ok, i was wondering about that, i hit about the same wall with my 6870 on air, i cannot seem to get it past 1100/1250 at 1.3v for gpu, however i notice once you got over about 82 degrees it seems to develope problems and artifacts. i am wondering if you have tried increasing your pcie voltage one the motherboard?

 

[Martin von R]

no pci-e voltage on this modterbord :shadedshu
0 errors in 3Dmark at max oc, it freezes just,inside the test 0 artifacts.
only error whit mem, if I go over 1250=artifacts.
no artifacts the gpu if I goes over the 1110 all stop/freez

Old vtt set,can help maybe,they did it whit HD4890.
no vtt set http://www.octeamdenmark.com/forums/extreme-mods/3958-ati4890-bios-voltset-guide.html
behind came to a verse from rbetool where you could put VTT, into then you could only put the mem with GPUTOOL where I could put mem to 1.275v, gift a lot of room for more oc

How are these factory overclocked cards possible if you can't change the core clock via bios?

 

[Murjuk]

They compile thier own BIOS so driver let windows boot. I think voltage changing is useless without clock change. So RBE became useless. I wish there will be solution to change clocks via BIOS.

 

[20mmrain]

I completely agree Voltage is useless if Clocking past CCC is unstable. For example with two or more cards ATI has a problem with that on some of their 6000 and 5000 series.

Will this enable more shaders or is it just for voltage and oc limits?

Thanks
