Hawaii Bios Editing ( 290 / 290X / 295X2 / 390 / 390X ) - Page 141

post #1401 of 3875
Hi guys, apologies for not being active on the thread today. Especially with your offerings. Got caught up with work.

7 X99 builds incoming. Parts are getting in piece by piece.

Hi guys,anyone have a his r9 390x bios with no offset?i try to edit my bios but i can't find the right hex values in table,anyone help me?
I read that for "no offset" rom,i must change the hex values of offset with 0,is right? rolleyes.gif
post #1403 of 3875
are you sure that you have offset? (see 2D DMP0 voltage)

about voltageinfo there are different versions of this table (same as with powerplay)
some have offset some doesnt

i suppose of yes,if i modify all DPM voltage table in hawaii bios reader the card modify the voltage in different mode as i input...is a problem of offset rom,i'm right?in practice my card ignore the voltage modification...

I present VDDC / VDDCI or VDDCR limit or Vmax in VoltageObjectInfo smile.gif .





Even though above is how I discovered VMAX register it is made up of 1st half byte as loop 1 (GPU) and 2nd half byte as loop 2 (VDDCI).

But really, I forget exactly but don't think I could even pass 1.26v or something with your highest offset Bios.


Do we have any reports of dead cards yet from voltages and stuff? Wondering how close I got with my 1.44v tests.
Warning: Spoiler! (Click to show)

My hands aren't even remotely stable enough to be poking the card with a multimeter either.

Set the voltage offset to ±0mV and you can set the VID to 1.368V, or you can set the offset to +100mV and use 1.268V VID.
Even with the lowest leaking GPU specimen produced (default voltage 1.2875V) you can use 81.25mV offset, and that´s just the worst case of scenario. On most cards you are able to use over 100mV offset with the limit present.

Good luck in reversing the limit wink.gif
It´s well doable, however the next time AMD might add a password protection on the VRM controller and after that the voltage cannot be adjusted with any software. Burnt cards (which in most cases are sent to RMA...) cost AMD money which they cannot afford.
Yes is doable smile.gif .


As we can't get IR3567B datasheet with detailed info, here is Vmax table from IR3565B datasheet.





As shown by info in first screenie and testing I did, the values for Vmax differ in IR3567B to IR3565B. I thought I set approx 1.260V limit but with LLC ON (ie no VDROOP) a DPM 7 manual voltage of 1.256V was being capped at 1.242V in MSI AB. Where as with a 1.368V limit it would = 1.258V.

Here is table of what hex / dec value corresponds with what VMAX value.

@emyhc

Please accept my sincere apologies.

This mod I will not be documenting more than what I have done in above post.

Anyone who understands it can help you, that is their choice and this is mine.

The reason why is, it's card destroying ability with this mod.
