Hi all,
I started mining with Claymore a few days ago and I am seeing an upsetting thing.
My GPU is an EVGA GTX 1080 FTW, watercooled, MSI Afterburner reports a RAM frequency of 5000 MHz, which is fine... but when mining with Claymore, the RAM frequency automatically drops to 4500 MHz. If I stop mining and start a game, the frequency goes back to 5000 - the 4500 MHz behavior only appears when mining using Claymore.
I suspect the driver somehow knows I am using Claymore and taxes me for that.
If I boost RAM frequency by +1000, it goes up from 4500 to 5500 MHz and the hash speed goes from 20.5 MH to over 25 MH - 25% boost - but this solution is clumsy, because whenever I stop mining I have to dial back the frequency boost, otherwise as soon as the GPU encounters any regular load, it tries to boost from 5000 to 6000 MHz and the memory can't handle it.
What should I do to keep mining with Claymore, but at correct RAM frequencies?

Remote manager reporting lost on my remote rig. It is mining just fine but it stopped communicating with it. Any idea why?

Try lowering OC settings or just not use that PC while its mining.
I would lower OC settings, just to extend life of those GPU.

Excuse me, When i'm use dual mining i got display problem.
quote from https://en.wikipedia.org/wiki/Digital_artifact
"Digital artifact in information science, is any undesired or unintended alteration in data introduced in a digital process by an involved technique and/or technology...
In information science, digital artifacts result from:
Hardware malfunction: In computer graphics, visual artifacts may be generated whenever a hardware component such as the processor, memory chip, cabling malfunctions, etc., corrupts data. Examples of malfunctions include physical damage, overheating, insufficient voltage and GPU overclocking. Common types of hardware artifacts are texture corruption and T-vertices in 3D graphics, and pixelization in MPEG compressed video."

I use pool dwarfpool and i have e-mail send when miner stop.
dwarfpool setting for e-mail is : write email instead password.
Claymore readme: parameter password is -epsw
My setting is -epsw [email protected] but when miner stop (crash) nothing happens. Miner not work hour and not e-mail send.
Why?

what is the default hash rate of RX 570 n 580?
28-31mh/s
This is incorrect. I don't think you can achieve these results without any modding.
You are right. Memory timing mod is required.

between 20-24MH/s before overclock and bios flash mods.

I have 2x MSI Rx 570 Gaming 4G that I can't modify BIOS unless I use pixelclock patcher which causes my miner to crash.
I have 4 other RX 580 cards that I modified their BIOS (using ATIflash) WITHOUT using pixelclock patcher and it works fine. Any ideas why this RX 570 card absolutely requires the patch? Is there any way around it?
Thanks for any help.

What about Ethereum Classic? Seems it have less difficulty than ETH and ~same profit. What can you say about it? In what is ETC worse than ETH?
ETC doesn't have the corporate infrastructure and developer backing that ETH does. That doesn't mean it's a bad coin, but IMO it will never reach the market cap of ETH.

Hey Guy's,
I'm having issues, for some reason on my one rig with 2 x RX480 8Gb just started to drop hashrate I use to hash around 60.4 MH ETC and 1080MH SC (sia) but since a week ago I dropped 1 MH on ETC and 8MH on sia. thus it gives me 29.4 MH etc and 1072 MH sia.
I've tried dcri values +- but still are the best where I'm at, both cards hashing at the same rate and on card is 2 months older than the other and overall these are mining for 5 months now.
Setup is as follow
Windows 10
Clock 1145
Mem 2150
undervolt -60
any known issues , I have read most of the last pages since Claymore 9.4. did not find any info.
Please helps this little speed drop does make a difference at month end.

I didnt mine for last 3 years so sorry for noob question but why i get same hash mining exp with 3 different cards with claymore all 3 cards have 8.5 mh per card 970,1060,1070 i am on win 10 and i reverted driver to 368.81, hash should be bigger on all 3 cards, same happened with ethminer and genoil, can anyone help. Thank you

Hey guys..
Am mining using GTX 1070 at ~29 MHs ETH / ~290 Mhs SC (Claymore Dual Mine (ETH/SC). My AfterBurner settings are below.
Can you advise on the following:
1) Do you think the OC settings are high and I might risk frying my GPU?
2) What are the ideal afterburner settings for ETH/SC dual mining using GTX 1070
3) I know a few people on the forums are getting ~32 mhs on GTX 1070. Any suggestions on how to optimize/improve hashrate? (Please provide the GPU AfterBurner settings?)
My Settings are below:
CPU Clock ~1550 mhz
Memory Clock ~ 4400 mhz
Core voltage - 0
Power Limit - 80
Temp Limit - 75
Core Clock ~ 100
Memory Clock ~600
Fan Speed - Auto

Hello,
i got following error when i try to start the miner:
OpenCL initializing...
AMD Cards available: 1
GPU #0: Hawaii, 3072 MB available, 44 compute units
GPU #0 recognized as Radeon 290X
POOL/SOLO version
Cannot build OpenCL program for GPU 0
Segmentation fault (core dumped)
I am running Ubuntu server 16.10 with installed version of amdgpu-pro-17.10-414273 and AMDSDK 3.0.
Please if anyone could give me a hint to resolve the problem.
Thank you very much for the assistance.

Hawaii cards are GCN 2 cards. The AMDGPU PRO drivers are only compatible with GCN 3 or newer cards. You need to use the Catalyst 15.12 or 15.9 drivers with GCN 1 or GCN 2 cards in Linux.
https://wiki.archlinux.org/index.php/Xorg#AMD
AMD PRO drivers do not require AMDSDK 3.0. Just, try them with the AMD PRO drivers. Try Ubuntu 16.04LTS, try an earlier version of Claymore miner, etc.
It's not the APPSDK. As it shows in the matrix I linked, the proprietary AMDGPU PRO Linux drivers don't support older cards than GCN 3. The open source AMDGPU drivers have experimental support for GCN 1 and GCN 2 cards, but don't support the AMD OpenCL libraries needed for mining. There is supposedly a workaround to get the open source drivers to work with the OpenCL libraries, but I couldn't get it to work.
The proprietary Catalyst 15.12 or 15.9 Linux drivers support GCN 1 and GCN 2 cards and the AMD APPSDK OpenCL. The problem is the Catalyst drivers don't support Xorg 1.18, so you have to downgrade the Xorg version or use an older distribution that uses Xorg 1.17 for mining with GCN 1 or GCN 2 cards on Linux.
https://wiki.archlinux.org/index.php/AMD_Catalyst#Xorg_repositories
This is also why smOS which is based on Linux, has two different distros. The RX series for GCN 3 or newer cards and the R series for GCN 1 or GCN 2 cards.

Hashrate Drop Every New DAG with RX480 8G this tack effect on last 3 dag ago
what can I do ??
This is most likely a hardware related issue caused by the DAG being over 2GB now. This causes something like the DAG now being spread over multiple banks of memory, slowing down access. The bigger the DAG gets, the more often the memory controller has to switch banks, the slower it responds. In reality it probably is a little bit different/nuanced, but I guess it comes down to the same thing. The most important question is; how much are the 290/390's affected? Because when they have it too, the majority is in the same sinking ship, so it's not that big of a deal. Good news for Pascal owners though, they should be fine as a similar issue was fixed when that hit the market last year.
So soon we won't be able to mine ETH with 3gb cards. Now, stupid question probably - will that happen just with ETH or all Ethash coins (expanse, musicoin, ubiq...)?
Will I be able to mine other ethash coins when eth dag passes 3 gb?
