BIOS for Sapphire Nitro+ RX480 4GB Elpida

Hi all
I recently got some cheap cards for mining - Sapphire Nitro+ with 4GB of Elpida memory which was originally clocked at 1750MHz.

As Polaris Editor doesn't work with Elpida cards, i started fiddling around with the Hexeditor and managed to copy the 1500MHz memory timing straps to the higher ones.
it flashed with no problems - command line:
> atiwinflash -f -p 0 almarley.rom

My test card was first running smoothly @ 29+MH/s while drawing only 77 Watts over the PCIe lines while clocking @ 1145/2050MHz with WattTool.
Funny thing is, that after a few hours it even speeded up to 34MH/s all by itself!! idk how that happened? Any ideas??
Unfortunately Claymore was then also throwing "incorrect shares due to overclocking" messages :(

Feel free to test my BIOS at your own risk.
All modding was done with switch on "silent mode" (towards the connector plate).

My card has PN: 299-2E347-100SA
MD5 of my rom is: 1f9e665e790df58349786a7db641ffb9 for checking
I'm on Win10x64 with Crimson-16.10.1 drivers. No further patching needed.



have fun

Mining for charity-OMF/Open Medicine Foundation. Need help!

Hey guys,

New here so looking for some help. Hope you are all good.

Im mining with the proceeds going to the Open Medicine Foundation. I am bedbound and severely ill from the illness they are researching ME/CFS (chronic fatigue syndrome). I am a former natural bodybuilder and powerlifter, so this illness can happen to anyone, and im sure you know friends who have or have had this. Im just particularly severe, though there are thousands like me.

On a lighter note my love of computing has lead me to here. I mined doge for shits and giggles and have always built pc's, thouugh cant do that anymore obviously. However I am mining via nicehash and Ethereum and would like some advice on what to expect hashrate wise.

Currently using (dont laugh) a 750ti...

However I am getting a 1060 tommorow and was wondering what to expect from it. I know its meant to be around 18-22MH.

Im using Windows 10 and have heard that I can achieve the above rate though people use linux or windows 7. Will 10 work? Ive updated to the anniversary update with WDDM 2.1.

Any pointers would be grand. And if you want to support or ask any questions about the research/mission, or even help out that would be amazing. Ive got a couple of people so far, and with some of the rigs on here even 0.5% would be amazing!

Anyway thanks a lot,

Ben

The correct way of powering the risers for the 470/480

September 1, 2016, 11:14 pm

Unfortunately the PCIe Slot power is at least 5Amps or so for the 470/480. Some of the 6 pin 480 even use much more than 5 Amps. You can't power too many of them with the daisy chain Molex and especially the SATA connectors. Even the 8 pin 470s draw around 5 Amps from the slot.

If you have the space, best would be to install NO MORE THAN 1 of your 470/480 directly onto the motherboard.

I would avoid using any SATA connectors to power any of the 470/480 GPUs. They draw at least 60 watts and those SATA connectors are generally used for hard drives which draw about 5 watts on average.



I wouldn't use any more than 1 of the Molex connectors to power any 470/480. Usually a PSU has 2 sets of these (6 molex in total) so you can power 2 GPUS from each seperate chain.






The best method would be as follows. Usually most PSUs have 2x 6+2pin on each chain such as follows.


You would plug in one of those to your 470/480 #1 connection and the other would always be unused. Since the length wouldn't reach the next card. So you would buy a PCIe extension cable such as below



Plug in the unused PCIe #2 connector to this extension and splice the other end +12V and GND directly onto your Risers power.



This way you could run any number of high power 480s and overclock them to the max and you would never have any melt since the PCIe has plenty of power and is a higher gauge.

Lets Talk about Fuel 230

This is a rig with 8 r9 380 GPU (from the pics although he claims they are rx480s) pushing 28mh/s ((Let me know your thoughts)) all running with an MSI motherboard off of 1 X 1300W EVGA PSU with Claymore as the web based mining software.

First question - I have only seen an MSI motherboard with 7 PCIE slots not 8. What board is this or what attachment is he running to cram 8 GPUs into this rig?

Second question - I have done a lot of bios modification research, but if these are rx 480's modded then they should push 30mh/s that's why I think they are r9 380's... Although I could be totally wrong.

Anyways, the item is on Ebay claiming to be the "fastest and most efficient rig available"


The floor is open for discussion as hopefully some of you guys are as curious about this as I am.

Download AMDGPU-Pro Driver Version 16.30 released by AMD.
The basics of the install:
1. download amdgpu-pro_16.30.3-306809.tar.xz
2. extract the compressed file to your home folder or somewhere.
3. goto that folder and now run the installation script "sudo ./amdgpu-pro-install"
AMD's page support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-GPU-PRO-Linux-Beta-Driver%E2%80%93Release-Notes.aspx
And here is the direct link to the compressed file:
https://www2.ati.com/drivers/linux/amdgpu-pro_16.30.3-306809.tar.xz
NOTE: You have to extract the compressed file and then run the script to install the driver to make opencl devices detectable (for ethminer, oclhashcat, etc.)
I am using 6 - RX 480 (4GB model ) in Ubuntu 16.04 LTS
Stock settings. I believe the ram is at 7000mhz vs 8000 mhz in 8GB version.

Preliminary benchmarks
Ubuntu 16.04 LTS
Driver is 16.30 for Linux
Genoil 1.1.7
2 - XFX 4gb rx 480
4 - Sapphire 4gb rx 480

Doing about 134-139 mh/s. I'd say its doing about 22.5 or 23mh/s in Ubuntu 16.04 in stock mode.
Next up is finding out how to overclock/undervolt GPUs in Ubuntu 16.04 with atitweak or something else (amdconfig/aticonfig do not work anymore unless I need to install the SDK.. we shall see.) :)

Ethereum Network Administration

I was curious as to how everyone is running their networks. I currently have a Windows 10 computer and then I have two Ubuntu machines doing my mining. I plan on doubling my mining efforts next week. Instead of changing around keyboard and mouse cables I though I would build a network so that I could control all of my miners from my Windows 10 box and so I was curious...

What are you doing to manage your miners?
What advise do you have for noobs trying to expand their Ethereum mining rigs?

Thanks

[Solved] Running Local Parity Node

Hello again team. How are we?

I've finally got my rig up and running after taking it on the chin and using Ubuntu Desktop as opposed to Server, and everything seems to be going pretty well. :) But now I want to up my game. Thinking about a few 6x R9 Nano rigs.

After doing a little testing, I've decided I'm going to Solo mine as I was getting a slightly higher hashrate using Parity/Ethminer than I was using Claymore on Ethermine.org, with a little more stability.

So my question is, is it possible, and how do I set up a local Parity node? Because I'm so new, not a programmer etc, all the guides mentioning API this, JSON and RPC/IPC that really mean little to me. Is any of this needed? In fact I can not actually find anything confirming that it's even possible. Just a lot of into about getting Parity and Geth to work together blah blah, which is what I'm trying to avoid (I think).

Is it as simple as running Parity on one of my rigs and run some bootnode command in Ethminer? I doubt it :smiley:

Thanks for reading!

So, it finally happened. I was advised not to go this way but since I was lacking a molex string from PSU, I still used the MOLEX-SATA for my riser. This is for an RX 480 card and damn right, this can really burn a house down. Take note this is not overloaded, just 1 riser to 1 SATA string to my PSU. To those who are still using it, best of luck guys.

So what's driving this rise in difficulty? It's over 63 trillion right now and it was 48 trillion at the start of the month. My mining profit went from 140usd to 110usd a month and I'm wondering why? Especially since eth dropped in price....

Can anyone explain this please?
Thank you!

Thread stuck in device driver error - XFX RX 480s don't work - tried everything

October 2, 2016, 4:18 am

Hi Community :) ,
I ran into a Problem while building my ETH mining rig. Setup:

4 x XFX Radeon RX480 Black edition
Equipped with (as of yet) 3 x Artic Accelero Hybrid III 140mm
Asus P10S WS
Intel i3 6100
1000W BeQuiet! Dark power Pro
Kingston HyperX fury 8Gb DDR4 something or other (I believe this is not important)

While doing some initial test runs, one of the cards gave out and I received a BSOD with "Thread_stuck_in_device_driver_error". Since then I cannot get windows going, with the card plugged in and drivers installed (it works with generic Windows drivers or in safe mode). I am confused about the fact, that the card itself isn't ignored at start up, and the rest of the hardware would keep going. Even the internal GPU doesn’t work when the card is plugged in.
The Microsoft Bug Check Website about the Error message is too specific for me as I am not a programmer.

Before this, the Mboard was already showing CPU over voltage error, which I ignored since all seemed fine in CPU-Z.

I reran the miner with the three remaining GPUs. In the night (coincidentally around the same time as the other one) the PC caved and another GPU showed similar symptoms. Surprising result: This time around, the GPU with the stock fan was the problem, causing me to believe that there is something wrong with either the PSU, the Mboard, or the miner (Up to this point, I blamed overheating of one of the VRMs or VRAMs in the GPU). Another weird thing: The second broken card continued to work for about a day in my old PC. When it stopped, it still worked in the second PCIe slot, but without any display output (I could access windows through TeamViewer, but the card was not recognised as a display adapter in windows’ device manager). Now I am properly confused about the whole thing.
I tried to flash the BIOS on the first broken card to no avail. BIOS flash works like a charm, but driver installation is still not possible afterwards. Can anybody tell me which devices on the card are active when flashing BIOS as compared to installing the driver?
Also, I cannot seem to get Ubuntu going, no matter whether the (hopefully not) damaged card is plugged in or not. It just shows the desktop background without any symbols. I can get into the command line but installing a driver doesn't work either.

I've already tried a clean install via DDU by Wagnard.

All help would be greatly appreciated, since I am absolutely stumped. Thank you!

Announcement of Imminent Hard

https://blog.ethereum.org/2016/10/13/announcement-imminent-hard-fork-eip150-gas-cost-changes/

"During the last couple of weeks, the Ethereum network has been the target of a sustained attack. The attacker(s) have been very crafty in locating vulnerabilities in the client implementations as well as the protocol specification.

While the recent patches have led to an overall increased resiliency in the client implementations, the attacks have also demonstrated that a lower-level change to the EVM pricing model is needed.

For many users, the most visible consequence is probably that they are having difficulties getting transactions included in blocks, and full nodes are facing memory limitations in managing the bloated state.

This is our strategy to address these issues:
  • As a temporary measure to minimize the effects of the most recent attack, we recommend all miners to lower the gaslimit to 500K gas.

  • A hard-fork based on EIP 150 version 1c will be put into effect at block 2457000. This will reprice certain operations to correspond better to the underlying computational complexity.

  • A second hard-fork will follow shortly after, aimed at reverting the current “state-bloat” introduced by the attacks. This second fork will serve to remove accounts which are empty; lacking code, balance, storage and nonce == 0.
We have implemented the changes required in the clients and are currently extending and adding tests in an effort to prevent the introduction of consensus-breaking vulnerabilities.

And as a reminder, the Ethereum Bug Bounty [2] is open and includes the new hardfork-implementations."
