Vmod 3850 through BIOS apparently IS possible....

[GenTarkin]

for those who may be interested:

BIOS for 3850 256MB v71 unlocked
3dvoltage @ 1.333v
3dcore @ 780mhz
3dmem @ 1030mhz
2dvoltage @ .974
2dcore @ 300
2dmem @ 830

bios IS checksum corrected.
I was able to flash with ATIwinflash w/ no problems =)

if you guys wish me to make diff clockspeeds bios's please post what you would like, I will try to do so =)
Thanks

Thank you very much for that one! Cards now run at 776/1026.

However, when usin CCC Advanced and looking at the Overdrive tab I get the message:
"ATI Overdrive capabilities have not been properly initialized yet. Please try again later"

Any clues of how to solve that? I have cleaned all drivers and reistalled it again, did not solve anything.

Thanks in advance!

EDIT: The service 'ATI Smart' is set to automatic, however, it only starts för a second then it stops again.

well it would seem that whenever the frequencies are programmed in the BIOS...as all of us have experienced here OVERDRIVE gets weird and stops working at least halfway. With the bios I edited the max on core was 730 in overdrive...since I programmed the bios to go above 730...I think OVERDRIVE is just totally freaking out. So, I dont think its nothing major. As Im trying to just hard lock in the frequencies without having to do any clock changes once I find whats stable =)

Flashed to your bios ealier and can confirm the same overdrive problem , i have a bios that doesnt break overdrive thats clocked 760/1000 with 1.33 3d , think its the only one i have tried that overdrive still works with , its the one i linked to on the first page , its not 71 bios with fixed max core thing , maybe thats why overdrive still works with it

Anyway im using your bios as its close to my max core 785 ish and 1035 , so its leaves a bit of headroom

cheers

Good thinking. I have the same opinion as you.

Before testing this one I had a bios with something like 766/1000 and max for me in Overdrive was 770/xxxx. In that case Overdrive worked but as I was already (almost) maxed out already it was just to leave the settings for clocks alone and keep benching.

I will keep your bios for awhile and see how it works for me.

chrisf: Is 785mhz max for you becasue of the voltage or temps?

Thanks a million ! Happy New Year 2008 !

Thanks to you, I have found the max for my card.

Can you make 797/1000 @ 1.333v checksum corrected for me ? Really appreciate your help. Thanks

Can you make it with the HD3850 default clocks?

Thanks!!!

here you go...same voltages @ stock clocks

yours looks tempting

Can I use it with atiflash via dos?

am a bit leery of doing any bios flashing from windows after my last escapade with my ASUS mb

(sapphire 256MB 3850)

ignore that...winflash is working...
