of course u can, but you got to disable signature checking on every bootup if you are on Win10.
another question If I choose to directly change stock bios via polaris editor by using Heliox's bios parameter, Do I need to disable signature checking on every bootup?
@boysie nice job with the BIOS. My cards are running great. Slight problem though I can change memory voltage in wattman but any attempt to change power limit settings always reset to zero. Got any suggestions?
change the button above it to manual, stupid wattman...:)
you are the man heliox! Low power rom is working great on my 3 sapphires and 2 asus cards. getting 30.5 mh consistent. For those having problems what I did was uninstall radeon drivers BEFORE flashing and then install the latest 16.8.2 drivers after you flash cards. After that follow the steps previously posted. The patched driver file doesn't seem to work with 16.7.2
Where did you find the low power rom at? I can't seem to find it, I only see the high power version.
@boysie Im able to edit everything in wattman with my msi using your sapphire bios. It just starts at 2250 as my min mem, and allows me to adjust everything, however this is my question.. Am I supposed to be able to adjust everything? The rom and bios are making me have great hashing power with -dcri 30. Im also reading 98W average over 6hours.

if you leave the settings on default ...as set by the bios you will get better. you can drop the mem power until it fails to save some power mine sits at 980...also -10% power limit helps save some more.
you should get 31.5 but watch the temps, you appear to be missing the -tt 75 setting in your config, as long as you have v6.0 + you will now get temp and fan control on claymores.
Here is a screenshot of my energy efficient tweaked Heliox bios. If Heliox, is ok with me posting a modified version of his bios. Then I will. Thanks Heliox.
This consumes less power, generates less heat, and almost same as high hashrate.

That's about the best you can achieve in terms of hash rate for watts in my view. I've pushed mine up to 80 to get an extra 7 MH (182) total. The only thing I would say, is if you put your fan up to 2200\2300 you should knock a few degrees off the cards (67/68) and not notice much audiable difference.
Q: What did you get the Mv's on the memory down to ? If it was 900 across all 6 you've been lucky with your cards!
I've had some issues with GPU failures in claymores beta as well over long periods. Have you noticed this ? I'm using 5.3 again as it's rock solid.

@Heliox thanks again for all your hard work, it's like adding a free video card on a 6-rig with your bios.
Attached is my modified bios with aggressive undervolting as mentioned earlier. It might not work for everyone, but I tested it on 18 video cards with 100% success rate, so I say it's pretty good odds.

I installed driver 16.8.2, I am just going back to 16.7.2 to see if that helps.

@Yogi never experienced any gpu failures before, maybe because I usually underclock than overclock.
Low Energy RomBased on 4GB version, my bad
Low Energy Rom OK
Correct one!
