Open beta test: 4770/4890/5850/5870/5970 owners

Right, flashed BIOS again, clocks are now increased to 900/1300Mhz stock, with 1.2V on the Memory in Register 0x15, yet clock voltage is not responding towards the changes I made in the BIOS. Any idea why not?
 
Okay, I own an PC 5870 LCS and so i was very happy to get RBE 1.24beta. I changed my Voltage to 1,225 volts unter Pressure and so, i get 1000 mhz cpu. I think that it would be enough. I used an ASUS bios. It works very fine.

Could you maybe provide a link towards the BIOS you used on the techpowerup BIOS section, and also tell em which of the following registers you altered for the 1.225V? I tried both 0x15 and 0x18 which didn't change a thing for me sadly :(
 
I tried the 1.24beta and i got a working bios of 725/1205 with all mem clocks at 1205, I did leave core voltage and speeds at stock though but i am glad this has fixed my flickering issue and there is no longer a need for a profile in CCC!
:D
 
HI,i have a Powercolor HD 4770 1st version and the rbe continue the same like version 1.22 or 1.23.

I just can raise the voltage until 1v, after that the sistem would recognize de videocard or just stay iqual like original bios.
 
The voltage increases seem to be working from my testing on the 58xx cards.. I assume it works on 5xxx cards as such.

nuno_p: I'm not sure I understand your post completely, but I will try.

You should download the 1.24 version of RBE.

Then, (if it is similar for the 4770 as it is the 5 series) , then you will want to use the GPU register button and change the 'highest' voltage setting there to your desired voltage.

Though, there is a limit to how high you can just raise the voltage I'm sure without problems, so you might be at limit, I am really not familiar with the 4770 in this regard.
 
Like i said on the other topic:

"I tried again to change registers and now i can reach 1.1v but not more than that.

better than nothing.

Edit: in msi afterburner i can raise until 1.2v."

I hope you understand the problem now. ;)
 
Hi there! I got a BSOD at startup (win7 x64, videocard Sapphire 5970 OC) with following config (slave edited same as a master):

and I can`t download beta version here!
 
Yeah I noticed that, but it looked like the 1.24 RBE was modified in Feb, so I figured it must be the latest.. but maybe it isn't. Bagz?

RBE 1.24 (Feb 2, 2010) used, but how can i get latest version of RBE to test?

Don't you think RBE v1.24 is a more recent version than v1.24beta? I took the beta offline so noone get this mixed up. Just download the official v1.24 release and be happy! :)

Official 1.24 can not make me happy :shadedshu

I used asus top 4770 signature file and it allowed me to raise voltage to 1.3v along with core clock up to 1ghz and memory 1,2ghz. Try it.

No, you can't. 5xx0 cards are not yet supported for signature frankensteining.

ups, sorry.
I thought that would work on all graphics cards
 
Can RBE change the CCC Overdrive limits? Like how ASUS 5850 & 5870 Core clock slider goes to 1200mhz.

If so, then it would be nice to make a custom bios out of this [S3C00101.104]: http://www1.sapphiretech.com/global/lib_files/120.zip

:confused: öhm, but I already did it :confused:

this bios is modified in this way:
http://www.speedshare.org/download.php?id=6515D99811

original data is this one:
http://www.techpowerup.com/vgabios/65298/ATI.HD5850.1024.091211.html

not only put the gpu-voltage to 1,225 V, the clock info 00 on 1000/1300 and clock info 04 + 05 ram on 1300 - I changed the upper limits with "method 2 - no hash" to 1201/1406
and it is accepted by CCC ... and already running well for some days :D

Method 2 - Maybe. But method 1 should definitely not be used as the overdrive data structure changed for 5xx0 BIOSes and a signature transplanting could render the BIOS inoperable.
 
I'm trying to decide which option to use for my HIS HD5850. If Method 2 works for all 58xx cards (is this certain?) then is there any reason to flash to a different manufacturer's (ASUS) BIOS? The purpose of doing that is to just change the clocks anyway, right? If this does the same thing it seems easier. Is it also as safe though? I probably won't go over 1.15v. Which would you recommend?

Actually I read of some Powercolor LCS (5870), Sapphire (5850+5870) and even one Gigabyte 5870 card where the flash did not work (clocks or voltages were not changed). But all those had no problems to flash back to their original bios. So try it - the risk is not so high.

That said, Method 2 does not appear to work with the Sapphire Vapor-X 5750. If I recall my (very late night) testing yesterday, Overdrive would still load and appear to be activated, but would not apply new settings, nor would it show the new limits. Reinstalled drivers several times. Reflash to original BIOS resolved the issue.

Oddly enough, GPU-Z seemed to report the card running at whatever I set the max to. By which I mean, using no modifications other than Method 2 bumping the Overdrive limit to 1Ghz, the card would load up and run 1Ghz at idle, despite the actual Overdrive panel showing stock settings and stock limits.

(Tried Method 1 as well, but having read the thread, I realize now that it shouldn't!)

Voltage control does not appear to work either. Any modification will cause the card not to recognize and drivers will not activate. I know the standard Sapphire 5750 uses the uP6201BQ controller, which is officially not able to be programed, though I'll have to check and see what it is on the Vapor-X when I'm home...

Would be happy to post up my original and/or modified BIOS if you'd like to look into it.

[EDIT] Damn! uP6201BQ on the Sapphire too... Call me ignorant, but if these things don't have software control, how is it that they can adjust the voltage down for PowerPlay? [/EDIT]

Zoork did post a link to a new Sapphire-5850-Bios (of January) and reported his success in tweaking and flashing:
http://www.hardwareluxx.de/community/showpost.php?p=13960935&postcount=901

Did the same: voltage to 1,225 V, clocks to 1000/1300 and clocks max settings to 1104 and 1406 with method 2. No problem incl. idle states:
