Now I'm testing with Load Line Slope to 1. For 1145mhz I need an 1.168v vddc VID with peaks to ~1.2v-1.237v and with ~1.15-1.175v (I don't have tested to lower it).
I have now 1140mhz with 1.156v vddc VID with peaks to ~1.18 and 1.125v vddci with a +25mv VOI offset. I'm testing to lower vddci to 1.1v, less isn't working.

To get 1.156v vddc I'm using a bios with 970mhz and not changing dpm7 voltage on it, because wattman voltage control seems to not be working, and then OCing increasing dpm7 clock with wattman to 1140mhz. I have to set voltage control to manual but not changing any voltage, bacause if not isn't working.

About wattman with 17.2.1 nowhql driver voltage control is working for dpm 7, but changing it at lower dpms is driver crash, an apparently isn't getting well bios voltage mods. With 17.4.4 voltage control seems to not be working at dpm7, and I don't know if it's working at lower dpms, but seems to be getting EVV voltages with manual.

So I'm changing only per dpm mhz in bios like this to get lower EVV voltages: Warning: Spoiler! (Click to show)

And then OCing like this: Warning: Spoiler! (Click to show)


Overclockers nightmare...

How are scores looking? Looking to improve scores? First part of getting max performance is finding your max tdp limits... higher than you would think is necessary for loss of like 30% at load so 30% more is needed for higher performance. Hotter sure but gotta find your cards max. lmk

I can maybe take a look at your bios and try something give me a min to lineup hex notepad++ and dial 'er in maybe haha been a minute.. my 380x isn't working but yeah I wish I had a reference 380x.

I get with 1145mhz and some memory timings mod (I see some error in games but in firestrike I see 1 or 0) a ~10050 gpu score in firestrike with 17.2.1 drivers, with the 17.4.3 I get 200 pts less, I don't have tested with 17.4.4.
I need a +35% power limit in firestrike with 17.4.3 but in games I need a 17%. I think that with 17.2.1 is only a +17% is needed in firestrike but I'm not sure. I get ~200W peakes with 82º max, with an ambient temp between 24 to 26ºC.

This is the bios I'm using now: 1250to15001625MemLLS1970-1450mhz1.156v6025mvvddc.zip 42k .zip file

So cool is this bios you sent the default bios Tonga.rom? Do you have that by chance?

I'm using this bios provided by sapphire cause of some fan problems, it's the stock bios but without the advanced fan mode: 308A0500.zip 41k .zip file

I'm testing 1140/1470, 1.156v vddc, 1.131v vddci with Load Line Slope to 1 and seems to be stable. I have tested vddci between 1.1v to 1.125v and it isn't stable. So apparently vddci is helping to OC the core like you say. But it's weird because it's to high compared to hawaii or polaris. I can't understand this.

I was able to change vddci like you said mynm. I increased it 50mv and vddc went down some. I don't recall details, but I played around with this before with the offset and it never helped me push beyond my 24/7 setting of 1135

OK thanks. So you had changed vddci via bios and isn't helping. What's your vddci for 1135?.

I have tested with vddci to 1.175v and I can't go for more than 1145 for 24/7 only for benches. I didn't see the vddc went down increasinf vddci.

Now with the shortcuts and AB it's easier to test the vddci. The problem is that vddci is to high and I don't know if going for more than 1.175v is risky.

1140-1145 is enough for me in terms of noise, temps, power consumption.

I lost a lot of my documents or maybe I didn't and I can't find how I achieved 1,250Mhz core clock and actually nearly 1,400Mhz for OpenCL Compute.

Basically the offset can't exceed ff or something like that... 1,250Mhz needed 1,449mv and offset could not exceed I think -250 ... let me know hmm... It had to be a certain value and go down from there...

I can't remember how I did it but the VDDCI must be "High" for 1,250Mhz... It's not that high I think 1,235mv or something for 1,449mv core for 1,250Mhz core clock.

Couldn't go into the EF FF range... ie -257 ... had to be -256 and below 00 FF ... no more than 00 FF for max clock... and it goes down from there -1 mv at a time...

So if you do the math for the clock you want you can determine what usVddcOffset is required...

So yeah lmk if you need help I can try and make a huge chart showing this.

Okay so to achieve your desired clock say 1135Mhz? To know the value... Go off of my 1,449mv 1,250mhz values... 1449mv divided by 1250 = 1.1592 ... Oh I remember now .. so basically +15.92% of the core clock was needed for voltage of 1,250mhz core... and then go down until you level out at +17.50% of the core clock...

1135 X 1.175 = 1333mv... Yes that's 380X though so the 380 can do it likely on 1293mv... This is barely above stock of 1.225v for 65288. At 1,135Mhz it can remain 1,175mv usVddcOffset....

If you think it's too much voltage, forget it because it isn't and comparing to hawaii usVddciOffset or VDDCI voltage of 1000mv is not even a comparison. Tonga uses way less power than Hawaii at it's 1,175mv usVddcOffset.

Thanks for the info. I don't whant to go for more than 1140 or 1145 for the core. Since crimson drivers I don't know if even aida voltages dump is right. You know that I need like 50mv more for the same clocks changin voltages on bios. Now I'm only trying to lower the dpm 0 to 6 voltages. But it's impossible with bios mod or wattman, changing dpm 0 on bios do not let me OC the dpm 7 via wattman or AB (senseless).
The only way I see to lower dpm 1 to dpm 6 voltages Is to use EVVs lowering clocks in bios and then OCing with wattman. This is working now with 17.4.4 drivers, setting in wattman manual voltages with out changing them.
And I don't konw if power % limit adjustment is OK, because I see different clock behavior between Afterburner and Hwinfo.

Other thing that I was thinking to do is to use some thing like a boost clocks to go for more than 1140mhz, like 1175 or 1200mhz, but not go for more than 80ºc and ~200w. But advenced fan mode isn't working good and more than 200W is needed becauses some times voltages don't go down and are still at dpm7 even with lower clocks.

Edited: I think that hwinfo clocks is showing same thing like a clock vid, if clock is between dmp 7 and 6 it shows dpm 7 clocks, etc, or some think like that.
I'm retesting the boost like clock to 1160 1.2v vddc, 1.175 vddci, with LLS to 1 and powerlimit to +10% and seems to be working in games with a max temp of 80º, fan to a max of 1813 rpms and 180w, the core is between 1139 and 1160mhz with vsync off.
