Would appreciate help in finding / editing the voltage offset in the RX480 Bios - Page 5

post #41 of 166
Yes, it's one of way (Only? - i'm not sure and would like to know)
I have my Saphire nitro 4g with offset added (+25mV by default) so I just changed it to -100..

yeah, the oc bios contains offset. I have some xfx 470 cards that don't have it, i read tutorials @gupsterg wrote (million thanks for them), but don't know if adding vddc offset works the same way as for Fiji cards. (especially Lards table calculator, is it OK for Polaris atombios?)

Just as an FYI on Polaris VDDC offset is static 900mv. It will also black screen above 65288 max of 1250mv.

Stock offset is static -350mv max meaning 1250mv - 900mv = 350. If you wanted to fry the card well past 1400Mhz, then VDDC Offset could be 1000mv or -450 yet stock 65288 max would need to be 1350mv to remain -350mv offset.

Any reason why you want to mod the offset? It's only for going beyond 1400Mhz only with extensive cooling mods to the VRM. As even stock 1250mv core max 65288 on -350mv offset of 900mv. It's extremely delicate operation sort-of, it's plenty stable but proper VRM pads need to be applied to even utilize the max potential of stock 65288.

I think this thread should morph into a VRM modding forum where you guy's are adding and testing materials and methods for VRM cooling and posting pictures and frame rate performance stats before/ after.

Only after you first achieve peak thermal performance of VRM and figure you have temperature headroom. Would you then want to focus on modding the offset for extra voltage for higher clocks.

no no you did not get me.
I want to have everything set in the bios, things i do in afterburner : set gpu freq, set mem freq and set vddc offset.
That way i won't have to use afterburner,trixx, watttool or anything else, because it will all be set in the bios.
I don't know from where did you get that 1400mhz and 1350mV smile.gif

I want to downvolt my cards, not the opposite smile.gif

Hahaha I was just informing everyone of this since the thread is over the modifying of the offset.

Sure thing bro, I get ya 110%. That's the best way to do it. Send over your BIOS and your determined ideal speeds. Let's dial er' in!

Yes.

The table that is modified by Lard's table calculator is common between Hawaii / Fiji / Polaris.

Thank you guys for helping me!
@chris, thanks for your offer, but i like to do things myself, that way i learn smile.gif
@gupsterg, by using your tutorial for adding vddc offset to bios, can i add vddc AND vddci offsets both ? Sure it will all be ****fted by 8 bytes, not 4, but the procedure should be the same right ?
post #48 of 166
I can teach you how it all works so then you know exactly how to accomplish what your trying to do quickly... If that's something your interested in? Start here with Polaris Bios Editor and ATIWinflash v274

atiflash_274.zip 1214k .zip file
PolarisBiosEditor-master.zip 31k .zip file

Oh i'm already an intermediate hexer Chris, but thanks biggrin.gif
I even made my own mini polaris editor, and actually want to implement vddc offset adding to bios-es that don't have it smile.gif
