There is. Anyway win7 problem is solved too. The same as in win10, but you haven't to enable IGPU or smth else.

Where did you find patched atikmdag.sys for win7? Or does the one for win10 work just fine?

The atikmdag.sys works on 7,8.1, 10 with no problem, file is same, even on 32 and x64 bit sistems, just use the same driver version for which the file is made

having issues dual mining with these roms both low power and the other one, not tried the boysie one though. Solo mining they work great 30mhs stable

dual I can only get 24 mhs and 390 sia pretty much stock numbers so right now I am just solo mining Eth with the modded boxes

is the low energy ROM Flash with all 480 8gb cards possible?

MSI Radeon RX 480, 8GB GDDR5, HDMI, 3x DisplayPort (V803-862R)?

I'm using the low enery Rom on my 8GB cards

something is up with this bios or the modded driver though, temps are fine ambient and on the cards max of 75 degrees but the hash rate will go from 28 mhs down to 10 mhs and averages around 24 mhs it obiviously can hit high hash rates but does not seem to stay there when dual mining.

Solo mining hash rates stay high.

if you find patched amd drivers for win7, the procedure is almost the same
but where to find?

I thought there is no BIOS signature verification for Windows 7. That is just new feature for the Windows 10.

More power in linux - with on-the-fly runtime changes - than Polaris BIOS editor gives you with flashing (NSFW): http://ottrbutt.com/tmp/custom-editor.jpg

Goddamn I love this driver. You need to write your own tools, but the functionality is there. That's just a small part of what I can control.

Where can I read more about how to do this?

I based a lot of my tool off of the Linux kernel source - there they have a lot of info on the formats. From 4.8rc2 on, the PowerPlay table can be changed at runtime.

Thanks for the tip.
But the flashing still need to change the memory timings.

mostly sapphire and several his, all with 2250 memory
i got one xfx and it died in several days with stock rom
btw you can also look at your asic quality, if it is low, then high power rom will work better and vice versa

Yeah I've seen success with MSI on another forum. Which ASIC is considered good and which is considered bad. My XFX is running with SAMSUNG GDDR5 memory per GPU-Z.

There are already some facts that this mod was done under win7 using Driver Signature Enforcement Overrider 1.3b

Will wait for card to come and try too ))

RX480-31.8HighPower.rom dual - ~29 eth, ~450 sia
RX480-31.8HighPower.rom single - >31 eth
RX480Mod.rom dual - ~27 eth, ~400 sia
RX480Mod.rom single >31 eth

Can you tell me which RX480 brand that you got 29 Eth and 450 SIA? It's not stable with my XFX. I can do the 29 Eth only for LowerPower ROM no issue. I am testing the 30.5 MH ROM right. Most of the RX480 (Asus, Powercolor, XFX) when on the stock ROM, I couldn't change memory to 2250+ without crashing so it could be the reason why only the ROMs with 2200 or less for memory is working for me. I'm using the same standard ASROCK H81 Pro BTC /Celeron / Win10 like everyone else.

ok finally got the rom to work, had to do a full re-install of the drivers , copy the modded driver and then boot with option 7

not sure how to get option 7 to auto load on boot.

One issue I'm seeing

dual mining seems quite neutered compared to stock ? at 30 dcri I am seeing 24.5 eth and 360ish sc when before I was getting 23.5 eth and 420 sc

now if I mine eth only I was seeing high hash rates around 31mhs

Also the cards all now detect and 4GB I know others mentioned that as well, it does seem that the core clocks are maxing around 980 which might be the reason for the low SIA or dual mining ?

so am i，xfx 480 8GB， detect 4GB，eth-only 30m, dual mining 24eth and 400 sc.

Will this ROM work only with the reference cards? Or will the custom cards also benefit from this ROM? Also like others have mentioned I would love to see a custom ROM for the 470 as well. You should share your BTC address or whatever coin you prefer donation address as well. I am sure the folks who are using and enjoying this new ROM wouldn't mind donating to the cause. Grin
