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

[tytanick]

I keep getting "not enough GPU memory to place DAG, you cannot mine this coin with this GPU". This started with epoch 351. I reinstalled Linux and it disappeared until epoch 352 today. I thought it might be a bad disk as it's not functioning so well but it's still the same on a new one.

I don't have this problem on windows 10. The whole reason I switched to Linux was it has less problems and is supposed to mine for longer. This can't be a memory problem as it's still mineable with over 250MB free. Also if the DAG size was the issue it would have stopped on card #1 ages ago as this has about 80MB less memory available but it's with all cards.

This miner is buggy and it's been like this even 2 years ago with 8GB cards. I see it's no longer being maintained as well and is 10 months old.

Yes. claymore should upgrade his miner to fix those 4GB problem.
But there are other miners on which 4GB cards are still working under SimpleMining OS.

Regarding windows, the main problem is that windows has graphical interface which allocates some memory in gpu.
Linux can be hadless and does not have this problem so putting 8GB makes sense only in windows.
Yet you can try in claymore using some options that load dag slower or uses different kernel.

If you have 4GB GPUs and you are facing errors then read this guide - what to mine with 4GB GPUs.

- OpenCL error -38 - cannot write buffer for DAG
- Creating DAG buffer failed: clCreateBuffer: CL_INVALID_BUFFER_SIZE (-61)
- CUDA error in CudaProgram.cu:373 : out of memory (2)
- initMiner error: out of memory
- or any other similar error related to “DAG” and “memory”.

Hopefully Claymore miner gets updated soon.

It seems claymore is done for if you have 4gb gpus at moment, PhoenixMiner still working with 4gb gpus but you need to know how to, lot of work, you will need to flash a new rom to make worthwhile.

I try to make it work Phoenixminer but you have to connect monitor to mobo video port so in case your mobo video port is a DVI port and you dont have a DVI monitor you can't do anything  GPU1 stops Phoenixminer and it just restarts mining over and over again... do you know if there is a command line to stop minig a selected GPU to fix this issue with Phoenixminer?

The same as claymore, the command line is -di, if you write -di 01 that means gpu 0 and gpu 1, -di 18 (that means gpu 1 and gpu .

update: First test shows that lowering memory speed and getting back to very old crimson beta driver helps for now, at the cost of 3-5% lower performance. Memory usage around 3,895 MB

HWinfo shows that old driver is using around 27-29 MB of dynamic D3D memory while new driver is using more then 130 MB, at least for me.

Can you please tell me which version of old Crimson beta driver are you using now? Will 17.11.4 do?

I too face 0MH/s with my RX570/470 4G since today on Windows 10, Adrenaline driver v19.20. Only monitor is connected to integrated mobo graphics (HDMI port), yet Windows still not allowing to allocate more than 3737 MB of VRAM (according to HWInfo). -eres 1 or 0 doesn't help, lowering GPUs' memory timings to 1700 (instead of ~2000) gives no change.

So last night my internet went out for a few hours and when it came back 4/5 of my amd rx480  rigs were mining at 0mh/s.  Windows 10 was popping up errors about how it prevent a program from using the graphic cards.  I assume this is a DAG issue.  But why would it happen after my internet went out? I tried to uninstall and reinstall 20.x amd drivers and pixel patch it with no fix.  Any tips?

Thanks

I would like to report an issue:

rx570 4GB cards with tuned bios, win10, latest AMD driver (adrenalin 20.7.2) - no mining after changing epoch to #352

Only first card shows 10 mh/s, the others fixed at 0 mh/s.

Normally around 30mh/s.

update: First test shows that lowering memory speed and getting back to very old crimson beta driver helps for now, at the cost of 3-5% lower performance. Memory usage around 3,895 MB

HWinfo shows that old driver is using around 27-29 MB of dynamic D3D memory while new driver is using more then 130 MB, at least for me.

What ver. of drivers youre using ?

17.30.1029 crimson beta

But I had to lower the mem speed from 2020-2080 to 2000 in all cards. If mem speed if higher the same situation shows up.

This crimson driver seems to be very sensible for modification of gpu voltage, memspeed parameters, so after each modification system restart is needed if some cards shows 0mh/s.

And don't forget to turn off automatic windows driver update with gpedit - win10 is keen to update this driver asap.

This means 29.9 mh/s for now instead of 30.9 mh/s.

Later I will take a look at other options.

Best Luck for you,

I HAVE 3 RIG  THE mainboards is same Gigabyte 970a-DS3p  
3x5=15  Rx470 Asus Mining edition have
Today I see no hashrate all rig. I restarted Same Problem. I edit my miner config And added -eres 1  rigs start to work. But I see 3 rig Same Problem GPU0  is not start to work hashrate Still 0 mh. But in device manager No problem.
I think this problem Claymore's script problem. I try reinstall driver and patch same Problem Still.
Any Solution ?

I fixed this too with command line -eres 1 and GPU0 is not mining the hasrate for GPU0 is 0.000 MH/s why is this issue?

Without command line -eres 1 all my rig GPUs hashrate drops between 0.000 MH/s and 1.200 MH/s.

With command line -eres 1 GPU0 hasrate is 0.000 MH/s and the rest of GPUs hashrate are between 23.086 and 23.386 MH/s

Can Claymore team fix this issue please?

The answer to your question has been posted 3 times in the last 50 posts. But to sum it up for you, GPU has overhead loaded into it. Either put a 6 or 8GB card as GPU0 or use on-cpu video.

I get the problem even when disabling the first GPU. The overhead is a poor excuse for a miner that is simply outdated. His Zcash miner is even more outdated.

So ... umm ... dont use it?

The point is not to disable the first GPU.  The point is that have the first GPU have enough extra memory for the OS overhead and still be able to load the DAG.  Then the rest of the cards will run fine at 4GB.  Disabling the first GPU does not solve the problem and misses the point entirely.

I FOUND SOLUTION 4gb cards

I have 5 460 cards in rig no onboard vga clay more no do solution. I use Nanominer  no need onboard vga Claymore Make 149mh  nanominer make 145mh I u can see monitor in 3333 port any software
one handicap is no fan control. I use fan control with Msi Afterburner and done continue to mining with 4gb cards.
