Hi , i have this card for bench but i need volt mod , the max volt i get is 1.158v .

tried to edit with rbe but it stay the same. the max i can get was 725mhz on air. tried on dice and it was the same - 725mhz.

I have seen very high results with this card, but I could not find specific information about it.

this is the card :

did you try gamerhud from gigabyte:

and i looked up but could not find info on volt chip? can you tell us?

Thank you very much, I'll try.

this is the mod i have sew : http://hwbot.org/submission/2336649_macsbeach98_3dmark_vantage___performance_radeon_hd_4850_gddr3_12620_marks

only pic i found but if you can tell what is your volt chip others could help better then me.

 

i think its ncp5388 ?? maybe

it's look like ncp5392 , i am not sure . This is the card a little hard to see what is written.

Frequencies are locked to 750/1200, I also want to unlock them. i tried with rbe Without success.

I made the pencil mod and could reach 780mhz but it's not enough , i want more with more voltage.

Gigabyte was using a custom pcb for both their models GV-R485ZL-512H and GV-R485OC-1GH.

 

And , yes , the IC is NCP5392.

 

Look for the ic pdf , to get help about the vmod.

 

Also measure the resistance of the spot , you are doing the pencil mod.

 

 

edit

You are doing the pencil mod here ???

yes, it's the pencil mod.

you need configure VID mod to go hight on core voltages , it´s only way to pass over voltage protection (OVP) witch will trigger above 1.3-1.35vgpu with NCP´s buck controllers!
