I have an avg of 27,1 now for the last 6 hours. Running on 29 now again while i'm back. Is it possible it has something to do with the temp? ( I opened the window and it's running 29 again)
Btw, i have 3 riggs here with 5 Sapphire Nitro+ 8gb cards, which rom wil push them to 30,5? (and still have the temp's visible for me ofcourse)

Mine do not depend on temperature

There is no rom for non-reference cards yet

Oops, i just flashed all my cards. I noticed everything going crazy, flashed the old rom back and it's all okay now.
Is there a ROM for the Sapphire Nitro RX 480 8GB card somehwere???

(still have no temp & speeds on my xfx cards in my normal pc after flashing with the 480lowenergyOK rom, how can i fix that?)

Most of the mod BIOS are for the reference RX 480. So you cannot flash them to your customer sapphire cards.

Im still using heliox rom, Rx480mod, now my hashrate very stable at 28mhs, not overclock anything just undervolt -15 to get more low electric fee.

i see someone using mod rom for power color devil but im never see about nitro version

anyway are you need the stock romof XFX black OC? i back up my old rom before flashing, if you need i will upload it.

just information : if you using claymore software for mining, then not showing the temp & fan speed of 2nd vga you must disable crossfire at radeon setting

Before i change roms i made another check.

GPU-Z showing under 100w powerdraw per gpu but the total consumption for four cards + system is around 738w from the wall.

738w - system 75w = 663w / 4 = 165w per gpu

Can someone confirm that their 480s @ 30Mhs pulling 100w from the wall measured with a killawatt ?

so 120 mh cost you 738 watts   gpu-z read 95 watts




I can do 101 mh at 610 watts  no flash  gpu-z read 75 watts

in both cases power is  about 6 watts an mh
 
6 x 101 = 606 watts
6 x 121 = 736 watts


can you try  to downclock  your 121 mh to 101 mh?  I am interested to see if you do 101 at  550 watts.



I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Phil,

It all depends on ROMs we have - theoretically it is possible to edit fily with HEX editor, but I have no idea

Also it looks like that some cards cannot hold the hashing rate, they downgrade to stock values very fast

Hi Heliox,
Is there a way to avoid this signing devices thingy for the 480s?
During the Nano rom mod days, it was as simple as flash and mine,
Thanks!

If I provided you good and useful info or just bring a smile to your day, consider sending me merit points to further validate this Bitcointalk account ~ useful for future account recovery...

I made it i guess,

rig1 = 112.31 MH/s @ 605 watts
rig2 = 109.06 MH/s @ 570 watts

Would be awesome if somebody could get a youtube video together for this and show the detailed step by step process. As I have said before, Ive tried for days and days to get this shit working and never has worked.

My custom wattman settings are good but the ROMS are 10% more hash and 10% less power than what I can do with wattman it seems.

It does not require any video

Actually citronix's tutorial is super - and it is enough

I will post here my tutorial for both Win 7 and Win 10
