Yes - you will not need to do it every time

max GPU ? 1145 or # 1145 (min to max)

no

open the signing tool "http://www.ngohq.com/?page=dseo" and sign that file. C\Windows\System32\Drivers\atikmdag.sys
open admin cmd window and type "bcded /set TESTSIGNING on"  if this command is not working try this: bcdedit.exe -set loadoptions  TESTSIGNING
reboot
Device manager, enable GPU again.
Write new bios
reboot
Done.

if i do this part i won`t have to manually disable driver signature every time i restart ?

ohh i forget... you need to modify your drivers aswell ^^

Boot windows
Install driver
go to device manager, right click on your gpu, disable it.
reboot to safe mode
replace atikmdag.sys

In my case nitro+ 8g core 1125 and mem 2000 works perfectly

WAITING for bios for extra mem timing strings (2100 and 2300mhz) that is too much for my brain to make extra strings.. Eliovp maybe little help with those extra strings!? ^^

Ok, I will try that later, thank you. Is there a thread/website listing good settings for GPUs so that I do not have to test all settings?

You can easily mod it yourself a little bit +2to4mhz. Save your bios rom with Atiflash and open it with PolarisBiosEditor. In the TIMING section copy 1500mhz strap(long code) and replace 1650, 1725, 2000mhz straps. Save and write new bios.

Exactly what you should get without tweaking it

There are no roms for aftermarket cards

I received my Sapphire RX 480 Nitro+ (4GB) GPUs yesterday. Is there also a ROM that I can use?
Without any modification I get ~22MH/s while mining ETH.

personally I havent tried and followed Boysie's work and rom -- so i can feedback any info.

for Heliox/Eliovp,ldw-vp work on the roms.... I have been following his work since R9 Nano ROM, which I am also using in my rig.
Cant wait for his latest 480 mod - my 6 x 480 rig is ready to be modded.

For burning cards and such..... its quite unfortunate that happen - its also dangerous - may burn your house down so be careful.

For mining in general, cant escape heat and power issues...

so:

1. always have additional fans, like box fans or desk fan to move heat away from rigs

2. powered riser cables - its there for a reason - at anytime the card needs more power, its has additional juice otherwise it will overdraw from the board and will likely kill your gpu, mobo and riser cable. ASrock H81 Pro BTC mobos have this feature where the motherboard has additional molex connector for additional power from PSU, in addition to powered riser. This is needed mainly for multi-GPU rigs and those nasty power hungry GPUs like 390s.

3. If you use Claymore miner for ETH, there is a -tt and -tstop swicth where you can stop mining if you reach a critical temp like 95% etc.

4. Btw, one additional thing.... buy a good PSU like EVGA, Corsair, minimum Gold, even better Platinum --- your entire mining investment's life is dependent, IMHO, the quality of power and efficiency of PSU - so long and stressfree mining - get good PSU.... that extra 20-50 dollars will make a difference.

Anyone else having a burnout issue?

So far we have heard one. I would like to know more. My both cards are running smooth 31mh. No dual mining for me. That uses a lot more power and card heats up. Single mining is working great with 1190/2250.

If anyone has a failure please alert others


Best luck mining yall

you can have as many names as you want....    as long as you continue your good work in ROM mods !

btw, when are you releasing this 33MHs Low Power 480 almighty rom?

Thanks for letting us know!

Haha

Let me help


I originally signed up here as Eliovp (basically my real name.. yeah.. now you all know..) back when i was 1 or 2 months active in this "scene".

As Eliovp wasn't available on IRC, i thought, mm let's choose a "nickname", Heliox sounds ok, (Is a term used in the diving world, it's a mixture of Helium and Oxygen "i really don't dive..")

So after that i registered on other forums as Heliox and on IRC it's also Heliox.

I created a new bitcointalk account "Ldw-Com" for when i'm at my office, it's only being used on my system that's next to my miners. ldwcom is the name of my business.

I hope i cleared that up for everyone

Greetings!

LOL... yes, thats his other name in Ethereum forum.

Shall we dig deeper?

Hmm...

Eliovp is ldw-com.
ldw-com is Heliox.
Heliox is Eliovp.

If using CDM or mining in general, use the fan settings generously when mining - its better for heavily abused fan than a dead GPU.

I use the -tt and -tstop settings always - the fans may run 80-100% but like I said, dead fans can be replaced.

I was waiting for these reports.  I mean hell let's put these to the absolute max and cross our fingers they don't burn up.  What your friend needs to do is flash it back to factory if possible before he sends it in else they find the bad rom he will not get warranty.  Like I said in a previous post here.  If you want long term this isn't the route.  Good luck
