First of all, I didn't ask about your opinion of whether I should start or not.

Your response is oxymoronic.. How do you know something without reading about it?

I'm asking for reading material, links, info.

My advise to you is to not be a waste of time in life.

I have a great project idea which might be adopted as part of a huge project.

First, I thought of Cryptonote. But then I thought I would need all the features of Ethereum.

How do I fork from the Ethereum network?

Any info is appreciated.

I have the following setup:

OS: EthOS latest, running fine with 3 GPUS
Motherboard: Asus Prime Z270-P
CPU: Intel i3
PSU: Corsair RM850
GPU's: Sapphire RX850 8gb

The rig has been working fine for months, just received my 4th GPU in the mail.
After plugging it in using this cable https://www.amazon.com/gp/product/B00A45JA52/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
All I get when trying to power up is a "click" from the PSU, and nothing else.

I disconnected the 4th GPU, and now only running with 3 cards.

Would there be a problem with running 4 GPU's on an RM850 ?

I turn the rig off, moved the switch on the bad card to the other side, and downloaded the BIOS rom.

I tried running Claymore without TRIXX or OC of any kind.

The card stops hashing within a minute.

I am really lost now.. I have no idea what to do..

Here's a screen shot of the ROM I downloaded from the same card (other side of the switch)
https://ibb.co/c67bvm

I am having a problem with one of my cards.
Unfortunately, I have not saved the original ROM for this card before experimenting with a custom rom.

Could someone please please please upload their original ROM for this card??

SAPPHIRE RX580 Nitro+ 8gb HYNIX MEMORY (WITH FLASH TYPE GD25Q41B)

Please help, I am stuck with a card that's off my rig without a correct ROM.

Thanks in advance.

The cards all have Hynix memory.

* Thanks for the link, I will wait a bit for someone to maybe post an original bios for GD25Q41B.
I also sent a msg to the OP here asking them to post their original bios. (https://bitcointalk.org/index.php?topic=1842537.0)

If nobody happens to get me their original rom, I will experiment with what's on that link.

That explains everything..  
Thank you very much for the detailed explanation!

I only have 1 original bios file saved from one of the cards that had the M25P20/c flash type.
I do not have the original bios file from the card with the GD25Q41B flash type.

It seems that the other two cards had the same original bios, which is why they work fine with the same original bios file but the third card doesn't.

Now since I don't have the original bios for the bad card, how can I find an original OR modded bios for it?!

I there a repository online where people post such files?

The only thing I did was use ATIwinFlash, and replaced the original bios
with the bios I downloaded from the description in this video here: https://www.youtube.c0m/watch?v=uiPCwJV_ryM

Again, the two cards with Flash Type M25P20/c are working fine.
Only the card with GD25Q41B is giving me issues.

I guess I'm missing something here.....

I went to check random things to try to find a clue as to what is causing the issue with that one card.

I opened ATIwinFlash and noticed that the card that's having the issue has a different "Flash Type" than the other two which are working fine.

The Flash Type on the card giving me the headache is: GD25Q41B

The other two cards have the same flash type: M25P20/c

The Flash Type remains the same regardless of which BIOS rom I use.

What is the difference between M25P20/c and GD25Q41B ??

Is it possible I'm using an incompatible rom?!

I'm using the one from this video: https://www.youtube.c0m/watch?v=uiPCwJV_ryM

Nope.. I've encountered that problem long ago and increased virtual memory to 20gb (only 16gb is required).

If anyone who is running RX580 Nitro 8gb can give me their specs it would really help.
ROM, Drivers, Claymore version, OverClock info.. etc..

I have my rig on standby now as I'm tired of restarting claymore 10 times a day.

I've been having problems with my rig for a whole week. I can't get it to run as good as it did when I first got it.

The problem started when I got the following:
1- "WATCHDOG: GPU0 failed to get OpenCL call"
2- Screen flickers..
3- Win10 notification about "WattMan settings have been reset due to system failure".
------
Here's my rig specs:
- Running Windows 10
- 3 GPUs of Sapphire RX580 Nitro+ 8gb (Hynix Memory)
- AMD BETA Blockchain Drivers
- Flashed ROM: https://www.youtube.c0m/watch?v=uiPCwJV_ryM
------

I have tried the following:
- Flashing Original FACTORY ROM, same issue happens, same card stops hashing..
- Reinstalling the blockchain drivers, same issue, same card..
- Running with NO OVERCLOCK, NO UNDERVOLTING, ETC.. same issue, same card..
- Changing the riser, same issue, same card..

When putting back stock rom and regular driver and running videos/games.. The same card works fine!
But when using Claymore 10 to mine, the card stops working.. Sometimes within an hour or two, sometimes in minutes.

Should I migrate to Ubuntu Linux??

What else can I do before I switch?

Buy Bitcoin and go to bed..

"A bit hidden"??

You're dealing with very technical people on these forums..
Programmers, web designers, system admins, etc..

If it's hidden take a screenshot and show it to everyone..

Ever heard of "PIC, OR IT DIDN'T HAPPEN!"? This is exactly what I'm talking about.

Stop trying to sound smarter than everyone here..

Getting out of bed to install this now.. 

Thanks for the heads-up!

This LIE is is straight from the manual..

The combinations are there..

I only use an 8 pin connector on each card.. working fine for me

Going to the store at 8 A.M tomorrow..
Will demand a replacement GPU and riser.. I'll play dumb and say I don't know about sapphire, etc..

"I bought these from you and now they're not working, you said 3 year warranty"

I'm in Kuwait.
Bought everything from a shop at the local computer mall (GPUs, risers, the whole rig).

So I'm supposed to take it back to the retailer and they'll send it to AMD?

That's comforting. Thanks!

I will still go to the shop tomorrow and will claim that the risers they sold me damaged one of the cards (which is a possibility)

I'm not comfortable with the SAPPHIRE TRIXX setting everything to ZERO on it's own even with the good cards.. I might just rebuild the whole setup and reinstall windows and disable all updates etc..

Things are going haywire and I don't have control over what's going on as I did before

The cards are only about 2 weeks old.
I live in Kuwait and this is the first time I have purchased from the retailer where I got the cards from.
Some retailers do play games and refuse to exchange merchandise after box has been opened.
I will try to take it there tomorrow and request an exchange, otherwise.. I'll send it directly to AMD.

If the card is dead, any chance they will know I flashed the BIOS?
Does BIOS flashing void the warranty?


I did isolate the card, no risers being used. It doesn't work when connecting to the motherboard.


I doubt it's windows, otherwise the other cards wouldn't work.
I will however try booting into UBUNTU and see what happens.


I'm using Windows 10..


I have just checked one of the good cards, noted the current modded bios number, re flashed the original bios.. and the numbers match. So yes, the BIOS version is the same according to GPU-Z


Interesting, I got an update within the past 48 hours.. Although I'm surprised only 1/3 cards is not working, who knows.. it might be something related. Will get back to you on this! Thanks!


No signal at all starting up the computer while connected to the bad card. Screen doesn't see a signal when connected to the bad card. I can boot into windows fine with the motherboard's built in display adapter and with the other two cards.

Two more pieces of info:

When checking things with Sapphire Trixx, both cards go back to 0 Clock, 0 Mem..
It's like something is setting them to turn off..

Also, I've just discovered that I have 1 bad riser.. it is probably the riser that caused this mess.
I tried connected a good card to it, and the card doesn't work..
Tried a different riser, good card works fine.

I now have a bad card and a bad riser!

Question....

If the card is indeed DEAD.. Electrically or otherwise..
Will AMD ship me another card? (I will take it to the shop tomorrow and see what they say)
