65288 is for DPM7 for the other DPMs are the respective 6528X value) and usVddcOffset, so usVddcOffset don't change VDDC only VDDCI.
*I think that it is sufficiently well explained how I had mod the 1.175vddci bios Edited:
If isn't, sorry, I can't explain it better. If you don't know how to do it, test your max vddc, core and memory clocks with Trixx or AB, and I will mod your bios.
*AtomBiosReader .jar is at ReleaseJar folder.
*Acording to this gupsterg post, dynamic VDDCI can be disabled. I had tested to disable it, and it doesn't work for me, but I did the test via windows registry, not via bios. Perhaps via windows registry isn't working. Do somebody had tested it?.
Thanks mynm. I'm also a big time hex editing novice. On mobile gpu's in the past I select the start/end offset copy pasted edited via gui app, then pasted it back. Usually not editing directly, although I did once increase a 7150m gpu from 128MB dedicated to 1024MB which was neat. Anyway I am not familiar with .jar's and don't know how to open them, sadly.
I think I'd like to leave the 65288 value alone because MVDD rises too high when changing 65288 to 1250.
I found a +80mv (from previous bios mod 1250mv in dpm7) or 1.337v on HWInfo yielded stable 1,188Mhz though only because MVDD rose too high for 1219Mhz stable. Mvdd rises when upping volts on the core when 65288 is changed to 1250, which made mvdd rise to near 1.25v causing instability. With DPM7 at 65288, only setting a vgfx offset resulted in 1.35v core, and rock solid stability mvdd of just 1.188v.
Basically is the reason I'd like to set an internal offset of +125mv for about 1.35v core voltage leaving the dpm 7 value at 65288 because of MVDD rising too high.**MY RESEARCH**
1063Mhz/1563Mhz stock 1.194v,1.188v
stock volts is 1.219v core, 1.188v ram
65288 stock bios +100mv 1,188Mhz yields 1.300v and 181 watts with memory no more than 1.188v at 11.222 watts.
Minimal TDP ceiling at 1,188mhz at 1.300v but 1,219Mhz at 1.300v hits the ceiling often.
So raising the TDP celing to 225 from 180 would open up 25% overhead since my thermals will certainly allow it.
At 225W TDP from 180, I could hit 1250Mhz
I found that 65288 bios allows 25mv less than with 65288 replaced with 1250. Meaning it can handle not only 1,188Mhz but also 1,219Mhz at 1.300v. (Referring to the 1.175 vddci bios mod)Where before it needed upwards of 1337mv just to keep 1,188Mhz stable and not 1,219Mhz.
1094Mhz needs 1244mv stable (+25mv offset)
1125Mhz needs 1263mv stable (+44mv offset)
1157Mhz needs 1275mv stable (+56mv offset)
1188Mhz needs 1337mv stable on 1.175 vddci bios mod, 1300mv on 65288 with +100mv offset
1219Mhz needs TDP increase, TDP won't allow it but 1.300v is possible
1250Mhz needs TDP increase, TDP won't allow it
Thank you very much sir.Edited by chris89 - 8/30/16 at 12:58pm
