Locked voltages on Sapphire 5850 Xtreme refurbished

[khrystiano]

Hi, I got this card and I've tried to raise the core/mems but it only reachs 885/1050 so I tried to unlock the voltages with MSI Afterburner but seems like the voltage managements is locked, I tried editing the .cfg with the unofficial overclocking mode = 1 and with the Overclocking EULA and that stuff but it didn't work, also, I enabled the voltage options on the program and nothing seems to work. Trixx works perfectly but I don't like it since raising the voltage automatic disables powerplay...

Any suggestions?

greetings!

bump! I really wanna know

Trixx is the only way I know to unlock voltages on those Sapphire cards (I have a 6870 from them), sorry. Maybe someone else has another idea.

 

[khrystiano]

Uhmm thank you.. so I heard about flashing the card with the 5870's bios but Im not sure if this would unlock the voltages or brick my card... can someone help me?

 

[psolord]

I have a Sapphire and an XFX 5850, both reference models and I had flashed an Asus BIOS on both, which was tooted unlocked back in the day.

Indeed I have had a great deal of overclocking and benchmarking fun all these years. I happen to love vintage hardware as much as the new one.

I can upload it somewhere for you, but I can accept no responsibility if all hell breaks loose for you.

Here are some of my recent vids with these cards, if you are interested (spicy wallpaper alert).

They can do 950/1200 with 1.2 V and a mildly aggressive custom fan profile in MSI Afterburner.

Okay, really thank you for the answer, do you think am I able to flash my Sapphire 5850 Xtrme refurbished with the Asus bios u mentioned? Will the temps increase on idleº? I don't really care about the loud, my fan is stuck on 65% so the temps on idle stay behind 40º...

 

[khrystiano]

I just find out my gpu codename is "Cypress Pro", it's a Sapphire Xtreme and the bios date is from 2011... flashing the bios can brick the card?

 

[khrystiano]

So I have another question. Isn't better to edit my actual BIOS with RBE and change the voltage (if it's possible which I don't know) so my card won't brick it?

 

[psolord]

If you change values in your own BIOS, it would be a better course of action maybe.

RBE will warn you if what you are changing will result in a BIOS that will not be recognized by the drivers, because that is a possibility too.

I mentioned that my cards are reference, so different compared to the xtreme. Maybe the xtreme has a different voltage controller or something.

All 5850s have the cypress pro chip, but that does not mean they are the same.

Yes a wrong BIOS will brick the card.

If you have a second card however, you can use that to boot and reflash your older BIOS which you must have extracted with GPUz beforehand.

You must be very fluent with all that however.

If you are not better leave it as it is.

Also if Trix works perfectly, why don't you use that for overclocking and just reset it after you are done gaming?

 

[khrystiano]

I would Trixx but the thing is when I set a voltage (1.18 to get 900/1200) and use the 2d mode (desktop, navigation, etc...) the voltage doesn't get low, it stucks on 1,18 and if I reset the voltage it stucks on 1,08 (on itle it works at 0.950 and 1,08 when it goes to 725/1000) so I need to restarts the system and that sucks...

 

[psolord]

Try doing the reset with MSI Afterburner instead.

Also instead of restarting, try logging off and on again.

 

[tweakboy]

Try a BIOS update if they have one. If not just uninsatll reboot and install it ... gb

 

[khrystiano]

So i opened a new thread because know that I don't care much about the "stuck voltage" I got other question...
