Voltage hungry! (solved)

post #1 of 31
Thread Starter 
Guys is there a way i could maybe up the voltage of my card?. I had flashed my XFX Radeon 5750 to the BIOS of the Sapphire 5770 Vapor-X(the vendor changed as a result). That had completely screwed up my powerplay settings and my card kept downclocking to 600/900Mhz while playing games. That really ticked me off since that shaved a good 15-20 frames off all my games. I manually used RBE to mod the BIOS and disable powerplay. I set the card to run at permanent clocks, thus conventional OC software such as afterburner wouldn't work for overclocking. I set the card to run at a constant 835/1250Mhz @ 1.125v. However, whenever i try to set a higher voltage, say 1.17-1.2v and set the clocks to 880/1280Mhz using RBE, the card crashes while on Furmark. What am i doing wrong? Is there another way to get stable higher voltages. What's the highest safe, stable voltage i could run the card at? Any help appreciated thumb.gif

You are not crossfiring 2 cards or more, it's redundant to set the 2D=3D clocks. Editing the 2D clocks are not exactly disabling the ULPS. 

 

You can try to overclock the card using Sapphire Trixx to find your stable OC for core/memory and the voltage to sustain it. Later, if you wish to edit the BIOS with the OC settings, that's perfectly fine. But after editing the BIOS then run the stability test is totally the other way around than it should.

 

The safe voltage and core and memory settings depend on your full load temperature on stock air cooler. I'd say 70-75°C is safe.

The thing is, i can't use conventional OC software such as Trixx or even afterburner. After flashing the BIOS, the card detected a change and kept downclocking no matter what i did. Even after pushing the slider, the figures show up but the card doesn't accept the overclock. So i HAVE to use Radeon BIOS Editor to change the clocks through modding. What's the max voltage i can apply to the card? A ballpark figure would do thumb.gif

If I look at 5770, it will somewhere around 1.2~1.3v depends on full load temperatures.

 

Don't get it to flash it with 5770 BIOS with all the limitations. Oh well, maybe you see the benefits outweigh the limitations.

I was wondering if i could overvolt the MSI 6770 card so as to get a higher overclock,i was thinking of something like 980/1260 or something like that. I have tried msi afterburner to increase voltage,it shows the voltage increasing but when i run the MSI kombuster burn in test at the side it shows all the details and along with that it shows the voltage at stock which is 1.125v,so is it that i can't increase voltage or is it simply that msi kombuster burn in test is not recognizing the increased voltage?

Thanks for the assist my man thumb.gif

I hadn't saved the original BIOS of the card so now i'm stuck with what i have frown.gif. I downloaded every XFX BIOS i could find but my card wouldn't accept any of them (i kept getting a 'subvendor' error). Any suggestions?

I downloaded and tried every single XFX + Sapphire BIOS from the site, none worked.

Now I understand why you need other BIOS.
