Thanks for your input. I think where I am going wrong is I have been relying on https://tradeblock.com/bitcoin/ to tell me what the fee size is. I think it's giving me the average fee size, not the highest at the time.

Thanks again.

Can someone please explain where I have gone wrong with my fee? Bare in mind that when I broadcasted this transaction the avergage fee was 60 sat/B. My fee is 100 sat/B which totals 0.00244634 but it's been stuck for like a day and a half or something.

Where am I going wrong?

It's the RSV-L4500. I am really happy with it. I have not had any problems using it for my rigs.

MacGyver is the Antminer S7 fan controller and fans. Helps keep the Missus happy 

I have finally dived into Ethereum mining and was really inspired by the Rosewill server rack builds I see here.
I built 3 rigs,

FrankenRig1

Biostar TB85
EVGA 1200w
6x MSI RX 470 Armor OC

The best hashrate I have achieved without bios mod is 142mhs

FrankenRig 2

Asrock Z97 Extreme4
EVGA 1300w
6x Sapphire RX 480

The best hashrate I have achieved without bios mod is 135mhs

FrankenRigPrime

Asrock Z97 Extreme4
EVGA 1300w
6x Sapphire RX 480

The best hashrate I have achieved without bios mod is 155mhs

What I can't understand is how FrankenRig2 is the exact same build as FrankenRigPrime, everything is exactly the same from the memory, cpu, hdd's etc but I can't get a decent hashrate out of it at all and then FrankenRigPrime is built and the first overclock I put into it (999 core, 2200 memory) and it loves it.








For those who are wondering, yes that is a hacksaw blade.

I am having an issue where my rig is mining but it isn't being displayed in my simplemining.net/dashboard. I have saved my email address to the config.txt.

I have noticed that in Ubuntu it says when starting,

YOUR EMAIL:
####################

and nothing updates when I change options on my dashboard

Thanks, I ended up making some cables that split one pcie into 3 pcie so I can power 3 risers from one pcie plugged into the PSU (EVGA 1200w)

Hi everyone,

I bought these risers,

http://holybitcoin.com/product/pci-e-1x-16x-6-pin-powered-usb-riser-card/

I want to know if I can power them with these, but only using one of the two 4 pin molex's.

In hindsight I should have bought the 4 pin molex risers instead of these 6 pin ones. 6 pins seems a bit overkill to me.

Cheers mate. Thanks for the advice.

I am building 3 rigs soon and it's only a matter of time before I want to tweak them to get the best hash rate that I can. I have never built a GPU rig before and all this custom bios stuff is a bit daunting to me.

What is the purpose of a custom bios? What can you do with a custom bios that you can't do in an overclocking tool?

How will this affect my cards when it comes time to re sell them?

How do I find out which type of memory my cards have?

MSI Radeon Armor RX 470 4GB

and

SAPPHIRE NITRO Radeon RX 480 4GB

I intend to use SimpleMining OS to run all of my rigs


Thanks everyone

I understand your pain. I had the same problem mining bitcoin. I ended up making a large enclosure to house all of my miners. I then put the A/C I wanted to use in my boys room and cut out a 200 square inch by 6 inch deep piece of evaporative cooling panel and used my antminer s9's strong fans to pull air out of the enclosure. I tell no lie, I swear. We recently had 2 115 degree days and my miners where around 194. Where I live has very low humidity in summer and the only things I have had trouble with are the stupid bitmain 1600w PSU's which are just plain dumb and don't last 12 months.

I have spent the last day or two studying your new and old threads and you have finally convinced me to start using my BTC mining profits to expand into ethereum mining. I have been wanting to do this for a year or so but now I am 100% going a head with it.

Thanks heaps man, I appreciate it.

The hashing board eventually stopped working. Good luck with your troubleshooting and thanks for your input. I hope you have better luck than I did.

So dropping the frequency din't work. I was able to isolate one hashing board which is causing the trouble. Every day it would cause the PSU to shut down so I have it connected to it's own PSU. This helps by preventing the whole miner dropping out which has bought me some time.

I am hoping someone can shed some light on what signals to the PSU to shut down that the hashing board is triggering. One thing I do notice is when I attempt to probe the 6 pin connectors connected to the hashing board to test the voltage, the PSU shuts down. Visibly I cannot see anything which could cause a short. Bare in mind that it only happens when the ambient temp gets to about 38C.

I will clean the contacts up with some contact cleaner to see if that helps.

Cheers

I have made some progress. At first I thought it may have something to do with heat because 2 days in a row miner stopped at the hottest time in the day but the miners temp was approx 60C at the time and I thought it may just be some sort of hardware error shutting it down at about 60 instead of 80C.

I directed some more AC at it and it seemed to work well but eventually died a little later in the day. Every attempt to restart it failed and I got the notorious 48 asic screen.

Now I am able to get it mining again at lower frequencies. 575 worked for a little while and now I am trying 568... The loss of hash rate hurts though...

I have ha a day or 2 now to see if the problem is solved but it is not.

The miner still is dropping out. It has dropped out 2 times in 2 days. Both times I can't get it to hash again unless leave it turned off for a while before starting it up again.

Over night I also had another hashing board on another miner drop some heat sinks. Am I the only one with this problem? Out of the 15 hashing boards I purchased, 7 have had heat inks fall off. I swear all I have to do is look at these miners the wrong way and they will drop heat sinks.

It is very frustrating also because desperately want to just leave the miners alone. Every time you touch them, the more likely they will drop heat sinks it would seem.

I ended up getting the 3 fans to show by plugging the 3rd fan in between the other two plugs. so plugs 1,2 & 3.

It is hashing now... but I am a bit sceptical because it doesn't explain how they just drop out randomly...

Fingers crossed... I have sent back a total of 7 hashing boards now... Not keen on another 3..

Cheers, I will keep you posted

I am working on the fan problem at the moment. I have 3 fans plugged in. When it works it says 54 asic per board, but when not working on this controller it says 48 and 0 temp... On another controller it says 30 asic and 0 temp and all dashes instead of 0's


I am using the bitmain PSU am using the october firmware.

Will get back to you guys ASAP, thanks for your replies.

I have been having nothing but dramas with my antminer s7's. For the most part it's just been heat sinks falling off.

The current problem I am having with them is that one by one over time they just die. It starts with a miner mining for a few days and then randomly it will just stop mining.

I restart it, then it will happen the next day again. The the day after that it will happen about 3 times. Then the day after that I am lucky to get it to mine maybe 2 times for an hr or 2 and then after that it's dead for good.

I have lossed a total of 5 hashing boards this way.

It seems like I am the only on having this trouble.

I have tried the hashing boards on another controller with the same result. I have tried a different PSU. The temperatures are fine.

When I attempt to start the miner after this, this is what it looks like.

The problem is likely your controller.

To get your 6 boards to work on one controller, copy the 18 pin data cable connection layout from the forum link posted before.

If you plug them into the wrong plug the controller won't recognise the hashing board.

I have the same problem with one of my controllers.

One of my boards in one miner won't show up unless I don't power on my controller board for about 10 minutes after the hashing boards. But they still drop out eventually. Sometimes 2 days, but other times, like right now, within minutes of running.
