Here are my undervolt stats for some of my various cards.
ASUS 280X @ 1.075V running at 1070/1600 ASUS 7970 @ 1V running at 1000/1575 Gigabyte 7970 @ 1.10V running at 1000/1575 7950 Reference @ 1V running at 1000/1575
All are rock solid stable. You can undervolt further but would have to decrease core clock. All are headless. If you plug in a monitor, it might crash.

Marvell1, Well, i had a feeling that it wasn't going to work. With those nano's, it's different, they're all reference designs, so my rom will work on any nano. I'm pretty sure of that. I didn't know what kind of 390 you have so i just took one of mine. Could you send me your rom, i'll mod that one and that will definitely work then Greetings! What is the brand of the 390 card you do the mod? Edit: I just found, it is the sapphire as indicated in your file. Sapphire 390 Nitro the one with 1040 stock clock Here are my undervolt stats for some of my various cards.
ASUS 280X @ 1.075V running at 1070/1600 ASUS 7970 @ 1V running at 1000/1575 Gigabyte 7970 @ 1.10V running at 1000/1575 7950 Reference @ 1V running at 1000/1575

Hey! I assume only core voltage mod? You can reduce the voltage on the mem as well. (Not all cards like that so much though..) Exactly, got some cards that crash when a monitor is plugged in as well Further, rock solid! Greetings

PM me your email address and I can send you the ROMs for all the cards thanks alot !

I'll do those, you test and then if that succeeds we'll do the rest or try to undervolt even more I'll send you a pm with my e-mail. Greetings!

ROms sent via email thanks in advance
Here, done. LinkThere's an experimental one in there as well, you could try it, but first try the other ones. Please let me know how it went. They all have -100 core voltage, and -100 mem voltage. Nothing else changed except the experimental one, i changed the voltage given to the memory controller as well. Please be carefull, i don't own any of these cards so i cannot test these. The roms i provided for Nano i do have and are tested quite well. The rom i shared for the R9 390 nitro works as well. Greetings!

So I tried the XFX mod, both mod flashed. It seems the core voltage is the same as before, there is no -100 mv voltage reduction. I do notice the VDDCI changed from 0.938V to 0.885V. I used the -100 mv aux voltage. The power consumption is the same as before.

Download AIDA64 (extreme is fine) Right click in the left bottom, go to ati and get me a dump there and share it please. With that info i can mod it more specific. Thank you. Greetings

This has become a bios voltage mod thread I managed to mod the BIOS of my Sapphire R9 380x Nitro, lowered the core voltage to 1075mv from 1200mv @1000 MHz core. Power consumption went down 40Watts. Now the power consumption is on par with my ASUS 280X cards, but the hash rate for ETH is better.

Sure thing. H81 Pro BTC Intel Celeron G1840 8GB Ram 6x powered usb risers. Lepa G1600 or G1700 PSU So single PSU, works perfectly (i can push all 6 GPU's to their maximum with an undervolt). I'm ready testing my latest rom. Reduced again some watt, not that much but worth it again. Will upload and share this today or tomorrow. Greetings!

I'm doing something similar but you do it better For the H81, you need to plug two molex connectors to the motherboad. So you do not need to use all the powered risers. I use 3 powered risers.

Nope you don't, if you have powered risers you don't need to power the motherboard with those extra molex connectors. Those Molex sockets are there in case you would use non powered risers. Greetings
