which is the difference between use a modded bios or use wattman in order to optimize the gpu ?
wattman is a pain and resets itself after every crash.

wattman is a pain and resets itself after every crash. Wattman is a pain in the ass for sure. thanks obama. anyways modded 470 bios is nice, on linux, but someone correct if im wrong you cant do it yet on win7 or 10.

Some ppl say patched driver is making problem with more the 3 cards on system, it should be more investigated Also patched DLL must be used just for the driver from which it was build
Also same card use different memory so that also must be checked before flashing bios from the net, even if the card is same model

You can, there's a patched driver, but you have to disable sig enforcement. thanks yeah, modded all my cards, basically just changed the timings. using trixx (fuuuuuu wattman), just make sure it dont restart

reference sapphire 470 4gb modded rom with the 1500memory strap timing set to 1625, 1750, and 2000: http://www.megafileupload.com/k2gu/470_4gb_sapphire_modded_bios.romI use -12.5% (1065)/850mv core and 2000/850mv mem for high mhs and power efficiency Size (256K) of your vBIOS is not standard (512K). It can brick GPU if flashed

It can brick GPU if flashed I noticed that message too. Seems 256k is the right size.. check out the size of other 470 (or even 480) roms available to compare the size

No. You need to extract your rom with atiflash, edit it with Polaris bios editor and flash it back with atiflash

What about the hash rate you are archiving with this ROM?

What about the hash rate you are archiving with this ROM? Also how is the power distribution with the reference 470? Reference 470 has 4+1 phases Reference 480 has 6+1 phases For the 480 4 phases are supplied by the 6 pin and 2+1 phases are supplied by slot. This COULD mean that the 470s all 4 phases get supplied by the 6 pin and only the +1 (= for vram) is supplied by the slot. The pci-e slot power draw from the ref. 470s would in this case be way lower compared to the ref. 480.

If not, it is still safer than the RX 480.

yes i have and i couldnt get it to work. it recognized the multiplier but i couldnt get it to recognize a vid card in the slot. even if its the only card on the pc. I think there is good reason more dont use these. There is a limit to the pcie lanes on a cpu and once you exceed that it will not post. I dont know why the splitter didnt work with only one card other than it has a proprietary chip onboard and maybe that doesnt like vid cards. ethernet adapter or modem etc mifght be ok, idk Best Regards d57heinz

256k is fine. 512k is also fine. Also, just to help you guys out, the "memory voltage" in the VBIOS can be set for Polaris (even using the editor) but it does nothing.
AFAIK this "memory voltage" is memory controller voltage and changing it via WattTool is definitely have influence on stability - when I set it less then 0.95v my card don't want to work with high memory freq. I change the gpu voltage with voltage offset option, not directly in table so I think it is not the dependency between gpu voltage and mem controller voltage that matters...

The editor changes MVDDC, which does nothing. You describe VDDCI/AUX - which feeds the memory controller, among other things.

Something i've been shouting for weeks  Finally someone who is on the same line!

Is that VDDCI/AUX in the editor? No. That is MVDD(C) - and does nothing.
So why if I lower it in WattTool below 0.95 with 2200 memclock I have instability? And no problems with 0.95 or higher
