Hey folks,

is my miner behaviour "normal" ?

I got no issue with my miner, my internet connection is super stable and my hashrate is at a constant 170mh/s, do you have any idea why the current hashrate fluctuates so much ?

Hey folks,

currently mining at 170Mh/s with 6*rx 470 4GB (MSI Gaming X), that's roughly 28.3Mh/s per card with 870W measured from the wall (total power consumption).

We can go a bit higher in terms of hashrate but we only have a 1000W Power Supply and we don't want to take any risks.

In terms of clocks and wattage, our cards are at 1100Mhz and 1050mV for the core and 2050Mhz and 1000mV for the memory.

Few questions:

1. Is it safe to draw ~870W from the wall, 24/7 with a 1000W PSU (Aerocool Gold+)

2. ~170Mh/s for 870W, is it a good ratio or do we have room to optimize the hashrate (without impacting the electricity consumption) ?

Our rig is mining at a steady 175Mh/s hashrate on Claymore (that's the hashrate shown on the claymore miner). No GPU error, no internet connection issue, everything is super smooth.

How is it possible that our current effective hashrate as shown on ethermine is ... over 200Mh/s ? More than 25Mh/s than our actual hashrate shown on Claymore.

Ok, thanks for the heads up !

Quick question: Afterburner doesn't allow me to overclock my rx 470s 4GB above 2100Mhz.

If I set the Memory clock in Claymore, can i go above these limits (I'm thinking ~2150mhz)?

If I understand correctly, miners will be able to start mining for the project at some point in the middle of 2019 ?

Late reply but I actually followed the guide step by step and it just... works !

Went from 1850mhz OC and 27ish mh/s with GPU errors popping here and there to 2100Mhz and 29.1-29.2 mh/s 100% stable so far, with ZERO errors.

Can't go above 2100Mhz since this is the maximum I can get to on afterburner.

We're already on the latest stable driver version, the 18.12.2 with everything on compute mode. We just tried the latest Clayrmore version (12.0), didn't make much difference, still stuck at 27.2mh/s on average with our memory clocks at 1850mhz

Hey and sorry for the late reply (Xmas and stuff!). We tried to things:

1. No bios mod, we simply increased the clocks and we ended up with ~25Mh/s with the clocks around 2050Mhz but with a shit ton of GPU#x got incorrect shares

2. We then bios mod the card ourselves (using Polaris Bios Editor), copying the 1500 strap values from 1500 to 2000. (we also tried with the 1750 values from 1750 to 2000 as well), and this is the situation where we are at at the moment, with 27.2Mh/s and a few GPU errors here and there on our GPU2.

This is our rig stats btw: https://ethermine.org/miners/f6c10F2CB2A2161efb43e4e0eabee60629329d5a/dashboard

Any advices would be much appreciated !

Yeah, I'm definitely not complaining about our situation (the rig belongs to me and my brother), I just thought I could squeeze a lil bit more out of our cards since I saw a lot of people having around 30mh/s with the same cards.


So we're using Windows 10 (with the latest update), the latest Claymore version as well and the latest stable AMD drivers (18.12.2). In terms of hardware we are using :

ASrock H81 Pro BTC 2.0
4GB of DDR3
a 1000W Aerocool Gold+ PSU
a Celeron G1840 CPU
and of course 6* MSI Gaming X RX 470@4GB

I managed to slightly increase the memory clock to 1860Mhz but I can't go beyond that.

hey guys, got a weird one today.

We built a new mining rig with rx 470 4GB (MSI Gaming X, Samsung memory and yeah, we're lucky enough to have free electricity), we copied the 1500 memory straps from 1500 to 2000 (like we always do), but for some odd reason we can't OC our cards memory above 1850Mhz without having the good old GPU#X got incorrect share etc... which means our cards are stuck around 27.2Mh/s.

You guys got any idea what the problem might be ? We have downvolted anything yet so our cards are definitely not power starved, I'm just a bit confused.

Hey guys.

We finally managed to tweak our rig (3*RX 570 Nitro+, 2*RX 470 mining edition) with a stable 28.5MH/S and a total of ~650W power consumption (measured from the wall).

We've only got one issue left, and we had this issue for a while now.

There's one card where we have to plug in our monitor (DVI), and this card is completely unstable. It's hashrate jumps between 15MH/S and 25MH/S.

We've tried a couple of things

- changing the settings (clocks, voltage, etc...). We even went back to the stock bios/clock/memory/voltages, it doesn't matter. The problem doesn't come from those settings.
- plugging in our monitor on another card
- changing the risers

It doesn't matter, whatever card is used for the video output, its hashrate is always lower than the other. I believe it makes sense, since this card has to work "more" in order to generate the video output, however I've seen tons of videos where people have a constant hashrate on all their cards.

Two questions

- Is there a way to fix this issue and keep our monitor plugged in on one of our cards ?
- If not, since we're using AnyDesk, we don't really need that monitor. However whenever we've tried to work on the rig remotely, without having a monitor plugged in, the screen resolution was awful. Something like 800*600, or probably even less. We couldn't even launch Radeon Settings, and we couldn't change that on Windows because the screen size was just too small.

How do you guys do to fix this ? Would it make sense to plug our monitor on the motherboard (we got an h81 Pro BTC 2.0 and an old IntelG1820).

Thanks for your help !

Quick question guys: I have put my private wallet address in the miner which is on an Exodus wallet (software wallet), is there going to be an issue for the payout (I am getting close to that 1ETH payout) ? I never thought about that, I see that most people have a myetherwallet wallet address linked to their miner.

Same question for a Ledger or a Trezor (hardware wallet). If I buy a Ledger, can I directly put the ledger ETH address in Claymores ?

Thanks, appreciate the help. That changes the equation quite a lot!

Back to my 7H/s, $1050 for 1 year contract.

Only fees I could find on the website were the slush ones, which are 2%

Using the calculator here https://www.coinwarz.com/calculators/bitcoin-mining-calculator with 0.02 in mining fees and $1000 (contract value) + 0.35*7*365 ($894.25) = $1894.25 in hardware cost, we can see that the profits over a year is $4786.37 with around 145days needed to break even.

Is it correct ?

edit: Damn, forgot to remove the electricity cost. Without the electricity costs the profits over a year is $7063 with 98days needed to break even !

Right so how can I exactly calculate my expected ROI using a website like https://www.coinwarz.com/calculators/bitcoin-mining-calculator/ ? Is there a way to find out how much the pool fees are before actually buying some hashpower on Hashflare ?

Also, regarding the maintenance fees. Say I buy 7TH/s of Sha-256 for $1050. With the maintenance fees being $0.0035/GH (which in turn is $3.5/TH), am I correct assuming that the only maintenance fees for the whole duration of the contract (1year) will be 3.5*7 = $24.5.

Alright thanks mate. If someone else could confim that the only fees we're paying are Maintenance fees that'd be awesome.

Also, regarding the pools, where do I have the option of chosing the pool I'd like to join ? I can't find it on my dashboard

Hi guys,

Just a quick question.

I know Hashflare charges MAINTENANCE fees, that's not an issue. But if I buy a contract for say, $1000, will I also have to pay POOL fees ?

I can't find any information regarding pool fees (I don't even know what pool Hashflare uses by default).

Thanks for your help guys !

Hey guys, a couple of questions

1. A friend of mine sold me the "regular" version (non OC, see here https://www.asus.com/uk/Graphics-Cards/EX-RX570-4G/) and I'm about to purchase some more "OC" version (see here https://www.asus.com/uk/Graphics-Cards/EX-RX570-O4G/) in order to finalize my 6 cards rig.

As far as I can tell, the only difference between those version is the core clock. Does this mean that I can use the same bios mods if they got the same memory brand ?

2. Any of you guys owns and mines with these cards ? I'm curious about their hashrate, cooler performance etc..

Thanks !

Not bad !

May I ask what miner you are using, and what model of rx 570 you're using ?

The problem is there here in the UK, the rx 570 is priced around £200 whereas the cheapest Vega is sold around £500. For 1 Vega card I can buy 2.5 rx 570.
