Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[Breesus]

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.

First of all, you have free elec
Even if those cards are doing 15Mh/s youll have good profit...

But ok

What is your config? Win ver., driver ver., etc

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.

those cards are bios modded or you are using an afterburner to set the clocks?

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 !

try the driver versions 18.xxxx
and with the compute patcher turn all the gpus in one shot to the compute mode and share if you get better results

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

Did you read the guide by Mattthev?

https://bitcointalk.org/index.php?topic=1954245.0

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.

Hi there!
All my rigs are still on Windows 10 build 1709. Has there been any development regarding mining on Win10 build 1803 and later? Is it known what is/was causing the problem?

I've had no issues with Windows 10 builds 1803 and 1809.

vcn and many other network features are broken on windows 1803, for now only 1709.

This is wrong, windows 10 builds 1809 and 1803 works like 1709, no issues.

@Claymore are you going to release a new version for Constantinople or that is not needed?

You gave some of your coins to claymore and got a headache for several months.
Think about switching to open source

Even with 12.0 I am still getting lots of bad keccak shares (with AMD and NVIDIA hardware):

Same problem here, I reported it a few weeks ago, v12 fixed it temporary.
But for me it is not all my 4g rigs, most are working, and I cant find any difference between the working and not working once.
They are all win10 beta blockhain drivers, only like 20% are givin'g dag epoch error not enough memory on GPU.
The working once I have benched to dag #299 no problem... wtf lol

[big_daddy]

You having issues with 4GB rigs on DAG file cannot be uploaded
Install any adrenaline 18.x.x driver, switch the cards to compute and use the last clay 12.0

And happy new year mining on

Happy new year
Still not work any solutions or idea for another miner

Move to any 18.x.x driver version, test on your config the best driver that will give best hash performance
Compute mode on, using compute patcher

Hint: install the driver only, without the amd settings cause the wattman will give you headache

[gsi5555]

where can I download compute patcher

I'm still having problems with a previously working rig now giving a black screen/stop mining, but rig is still powered on (soft crash). Could this be a SSD error? It was running 5 GPUs OC'd, undervolted. running at 750w on a 1K platinum PSU. Even at stock clocks, the rig still soft crashes. All i get is the kernal error 41, so no help. Is this a symptom of bad riser? What i'm doing now is running things OC/UV but taking a gpu completely out of the equation with each subsequent crash to find the bad riser or gpu. Thing is, hwinfo reports 0 errors on anything.

Help get my rig back to stable!

Hi there
i got same DAG issue here also,
 v12 fixed it temporary
Only 1 of my 4g rigs is affected,   others 3 are still fine on claymore 11.9
i follow the previous comment
So on that rig, i install Adrenaline 18.8.2
i patch it (because mod bios)
reboot
i use the patch to switch to compute mode using the tool (https://bitcointalk.org/index.php?topic=2815803.0)
reboot
testing Claymore 12.0 , now it's mining but..... my card are running at 14 MHS instead of 28 mhs,    same thing if i enable or disable my OC in msi afterburner
Any idea ?
Thank you ! happy new year

Because Windows 10 reserves a lot of GPU memory. Also this issue can be if not enough physical RAM is installed, Windows requires some physical RAM when GPU RAM is used, virtual memory helps but some additional physical RAM is required anyway.

They working because they have a little more physical RAM.
I had a reduced hashrate with drivers v.18. *

Now Windows 10 x64 build 1803/ 4GB RAM /Rx570 4GB /drivers blockchain beta / Claymore v12 - working well.

Ok my issue is now resolve (for now) using this Adrenaline driver, following all the same steps after.

ps i have 8gb ram (4rx470 4gb) and virtual mem has been increased

Hi guys!
Have a problem with a rig 6*470rx - DAG issue (not enough GPU memory).

I've updated AMD driver to 18.12.3
But now I can not patch (by atikmdag-patcher).

Can you help? Or any other idea?
Thanks
