I did what you say and it works. I wonder why.

However, after that I just remove the hdmi.

Guess what? It still works.

So like they got to meet TV once.

Where can I download 16.9.1?

So it has to be older drivers?

Do I need to make sure that the serial code for the product is the same?

How do I get the exact bios version number of the one currently on my card?

1st. Take custom bios as is flash to your card. I did this and brick my card. I can unbrick it of course. Doesn't work. Often even if my card is RX 480 Sapphire Nitro OC with samsung memory, a bios for another RX 480 Sapphire Nitro OC with samsung memory may not work.
2nd. Take custom bios, change some id in polaris editor using my card and flash.
3rd. Take custom bios, copy the memory density and time strapping to current bios and flash.
4th. Take current bios, change memory strapping based on something.

Which one did you use and which one is right?

And why is that?

Also my mining rig have 6 GPU. If I connect LCD to one will watttool be able to read card data on the rest?

I also have a normal CPU with 1 GPU. I don't even connect anything. Basically I access the computer via remote desktop. Yet watttool and stuff can do it's job.

I've been thinking the following. Say network difficulty fluctuates wildly. Miners that come only when difficulty is lower will be more productive. How would a pool recoqnize this? Which pool recoqnize this instantly?

For example, this is pretty much what I understand from what miningpoolhub says. It's a PPLNS pool.

Say a coin has difficulty 10000

Block 1 is found after 10k shares
Block 2 is found after 10k shares
Block 3 is found after 10k shares
So N for block 4, based on what miningpoolhub says, is 10k

Then suddenly difficulty drop to 1

Now, each "share" should worth much more right.

However, the way I see it is because Block 1, 2 and 3 requires 10k shares, someone mining block 4 when difficulty is much lower will have their shares worth the same way with someone that's mining block 1, 2, and 3 without caring that productivity is "low" at those blocks.

How does pool in general implement that shares that are given during low difficulty worth far more than shares that are given during high difficulty.

This is important for those making bots to buy hash to send to miningpoolhub because, of course, we would send hash only if difficulty is lower.

One thing I would imagine is to implement N in PPLNS in such a way that N is always proportional to difficulty when a block is found. So if difficulty is really low when a block is found then only few shares get a piece.

Another way to implement this is to have weighted share. So each share is divided by difficulty and people get paid based on those weighted share. Obviously share that are earned when difficulty is lower worths more.

The reason I ask is because pool's difficulty is pretty much constant while network difficulty may fluctuate wildly.

Basically do people get more share if they send hash when difficulty is lower and how automatic is that?

From what you said, it seems that people get the same share and the expected value of how much those shares worth (inversely proportional to N) is not directly derived from difficulty but depends the amount of shares required to mine last blocks. It is possible that amount of shares required to mine last blocks may be far higher because those blocked are mined when difficulty were higher.

What exactly did miningpoolhub do? When difficulty is fluctuating and the round is the same, how did miningpoolhub reward those who hash during low difficulty more the way they deserve it. Or is it just being ignored?

I uses asrock BTC

However, I connect hdmi to the motherboard's hdmi port instead of to the gpu hdmi port.

The result is after burner and watttool is not functioning properly.

Some says that I should have put the LCD hdmi on the GPU instead. However, I do not understand why would that make any differences.

I prefer to collect many kind of coins.

But not too many.

BTC, LTC, Zcash, Ethereum.

So I want to auto exchange the rest to ethereum.

For those I want to keep, I want to just autopay. How do I accomplish this?

Let me try to understand.

What is a share?

Some says that not every hash count as a share. You have to multiply that by a certain number first.

So only hash that serve some difficulty would work.

Say difficulty is 1000. People submit about 500 shares. Then suddenly difficulty drops to 1. So  https://miningpoolhub.com/?page=home&normalize=none  will report sky high value right?

 Obviously it's time to send massive hashing power.

Now, say people send 1 share and the block is solved. He got 1 BTC (obviously we don't mine BTC, but this is just for simplicity sake).

How much money he got?

Notice it's not just luck. The first 500 shares are mining when difficulty is high. The guy that send massive hash when difficulty drops is the one getting you block. How would you distribute the fund?

N is average of last few block's share sum.


I think you are concerned about fair distribution. It's quite fair because pool distributes to miners according to their time and difficutly.
You are collaborating and competing the block reward with other miners in same pool.

I use RX 480 and got only 24 Mh/s

Is this normal?

Do you modify bios or do anything else? Overclock and others.

So you use last few blocks? How few? Last 10? Last 20?


I am not aiming for 2% profit difference. I am aiming for 30% profit difference. Sometimes price in nicehash differ from price in miningpoolhub by big margin. I uses bot. And after exchange and stuff, still lost money.

I will try again and tell you the result.

I saw Crimson 16.11.5 I do not see Catalyst 16.11.5

Does Crimson 16.11.5 check signature?

This one says that

https://forum.ethereum.org/discussion/11159/rx-480-sapphire-nitro-oc-4gb-modded-to-8gb-31-mh-1225-2200-mhz

Amd catalyst center version 16.9 or 16.11 other versions need t

So I like to use just that. But I cannot find AMD catalyst center version 16.11

Where can I get that? Is that a driver?

And what should I do if I can't find it?

So this is real coin value that takes into account only difficulty and price

https://miningpoolhub.com/?page=home&normalize=none

Hmmmmm...

How exactly do you set N in your implementation of PPLNS? So it seems that there will be some discrepancies between current difficulty and the amount of share we get. It is possible that difficulty is really low but we got low share or difficulty is high because we got high share. That's because your average time between last few blocks may have changed.

That's what I am concerned about.

If it's constant N = 2* difficulty or share is inversely proportional to difficulty then that number in https://miningpoolhub.com/?page=home&normalize=none will be directly comparable to numbers in nicehash.com

I get the impression that it's not always directly compatible

Actually what is AMD catalyst center?

This one https://forum.ethereum.org/discussion/11159/rx-480-sapphire-nitro-oc-4gb-modded-to-8gb-31-mh-1225-2200-mhz

says that I should download

    Amd catalyst center version 16.9 or 16.11 other versions need to be patched to work with modded bioses as they check for the bios signature and will deactivate the card

The problem is, other versions of what?

What is catalyst center? Is it a driver for AMD radeon or what?

I thought the drivers name is called crimson

Where can I download it because I do not see catalyst center 16.11 anywhere on page mentioned.

Will this work?

http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-Edition-16.11.2-Release-Notes.aspx

It says Crimson. Not Catalyst.

Actually which one is better? Mod my card and do ethash all the way or use nicehashminer?

I checked this https://github.com/aaronsace/MultiPoolMiner/releases

It always mine claymore everytime I run it.

I know.

Because if I overclock my memory to 2250 the stuff will crash if it tries to mine other stuff like cryptonight.

So I know that miner never switch.

This is my start.bat
powershell -version 5.0 -noexit -executionpolicy bypass -windowstyle maximized -command "&.\multipoolminer.ps1 -username pornluver -workername multipoolminer -interval 60 -location europe -ssl -type amd,nvidia,cpu -algorithm cryptonight,ethash,equihash,lyra2z -poolname miningpoolhub -currency btc,usd -donate 0"

Maybe because I donate 0 it doesn't switch? Doesn't matter. The best algorithm is always ethash anyway.

Don't know what interval 60 means.

I overclocked my memory clock.

I got 27.8 MH/s and everything is stable.

However, I can no longer run nicehash miner.

Basically the system always crash everytime I tried other algorithm. I have no idea whether this will cause any permanent damage to my card, motherboard or anything.

It seems that overclocking is not a good idea if I wanna do multi algo switching. I got to do ethash all the way.

Am I correct here?

What about custom rom? Do all RX 480 have the same custom rom or do I need to search for exact one that match my card? How do I know the exact type of RX 480 for my card?
