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

[xanx]

Hi all, I have a new rig and I've tried all the tricks in the book but my cards are stuck at 22mhz. I've tried all the different crimson drivers, re-installed windows, did DDU, updated the BIOS, tried different version of claymore, modified afterburner config and still nothing. In afterburner if I try to overclock memory past 1900 i get blue/white screen and even if I go less than 1900 my hash rate decreases from 22 to 19. Any suggestions how to fix this? I am trying with rx480 4gb on windows 10 claymore 9.3 and crimson 16.9 (but have tried other versions).

Try the newest AMD drivers (I think 17.3.4 or something like that) and then use them using the Pixel Patcher (Google for it). I am using the newest drivers patched and they are hashing well. Are you sure you used a modded ROM for the memory type in your card. The memory used in the cards can change from run to run. So a mod for your card for one memory type might not work properly or has well if you have another memory type in your card. Check out youtube videos from cryptomined and others. They have lots of good information about modding, putting together rigs, etc. It also might be an issue with the BIOS on your motherboard. Some just do mine well. Make sure your motherboard BIOS is the latest available for your board.

I have the latest version of my bios and have tried latest crimson drivers- I have not modded any of the cards unless you meant memory clock which I have tried to modify but computer crashes every time I do so. I will take a look at the pixel patcher you mentioned. My board is a z97 guard pro.

To get more speed you need to mod the VBIOS on the graphics card. There are many youtube videos on how to do this. On most cards, depending on the memory (use GPU-Z to read memory type) and copy the memory straps from 1500 to all higher values. You need atiflash 2.7.4 and Polaris editor. Search youtube for videos on modding the bios for your band and type of card. Then go from there.

Everything worked but now the issue getting over the 25-26 hurdle, every time I over clock past 1950ish my screen goes to black/blue/white and have to restart, any ideas how to overcome this?

Stupid question here, got a few Dell Vostro 260 at work, 1155 socket, 4 PCIE, i3 Processor, 4 GB memory, for some reason there is no way they will even boot if I install a R9 380 on the mobo, not even blink.
Strangely enouhg we have some Dell Vostro 230, 775 socket, Dual Core, the work like a champ, any idea of what could be going on?

Any help would be appreciated, thanks

Most likely your PC does not support UEFI BIOS. Therefore modern cards are not compatible.

That´s kind of strange, Vostro 230 is an earlier generation with a 775 socket and a dual core, it has no problem running the RX 480 at 30 Mhs, sure that one does not have a UEFI BIOS.
What really bugs me its the fact that it doesn´t even try to start/boot, well was just looking at some extra Mhs with free electricity

How should I set the -eres value if Claymore crashes miner during reallocating of GPU buffer for new DAG? Lower or higher? I'm running 4GB RX 570's.

edit: tbh it only seems to crash when I turn on the monitor funnily enough. Otherwise it chugs along pretty nicely.

PS: is there a way to have the log record the GPU temps?

Hi,

I've a problem with claymore. After few hours the miner get only bad shares on ETH mining (with DCR all seems ok).
12 hours stats:
- Good shares: 11.041
- Bad shares: 134.523

I actually use ATI RX 580 with latest driver version.
 
Can someone help me?

Hi Claymore,
I can't use USB wireless adapter tp-link 722n with Claymore v9.3. Every time mining starts, the internet connection immediately stops.
How to fix this problem, thank you.

+1 I am having the same problem. I have to manually re-plug the USB stick.

Do not use wifi adapters, your rig cause harmful interference for wifi

Hello Claymore,

 when you will implement voltage control under Linux?

i got a few vostros when work junked them during upgrades. vista business keys, various core 2 duos/quads cpus, 3 to 4 gb ram, no hds, hd3450 video. some models worked with multiple cards with upgraded psus, some would only take one video card and not see two (plus lose network when 2nd card was installed.) tried HD6870s, RX470s, RX 380, RX 390s. all worked as a single card in the single card only vostro, all worked at the same time in the vostros that took 3 cards ok. power supply was a seasonic 850 in the vostros i tried

all mobos had latest bios flashed.

seems luck of the draw really. sorry dont recall the model numbers. thought they were 200s series though, matx boards with 4 pcie slots, 1 x16, 3 x1s. all had a HD 3450 in the x16 slot. as i recall the HD3450s dropped like flies with artifacts on boot/bios screen. had like 4 bad cards out of 6 vostros.

only suggestion i have is try different slots. make sure to upgrade the psu, vostro psus are, well not total jusk, but not really quality you need for miners. usually low efficiency. dont use adapters like 2 molex to 6 pin peg if you can help it use straight 6/8 pin pegs direct from psu.

tl;dr vostros are hit or miss.

@ Claymore:
Can you make miner to reignite card that is stopped due to high temp and "-tstop" commamnd? I mean when it cool down so it can mine again?
Like " -tstart 60 -tstop 85 -tt65 "

I have an offtopic question. Is better mine withe Claymore's and use the pools or to use NiceHash system? Which one is more profit and user friendly?
thanks

Is that so?, was wondering why would it be that using wifi to connect the rigs would not work, keeps connecting and disconnecting even if the signal does not drop

I've got a bit of an issue with one of my rigs... 3 RX 570 are hashing at 28MH/s and the other 3 at 25... For no apparent reason. They've all been flashed with tighter straps and using Claymore to overclock them. Why doesn't the o/c stick for 3 of them??

[dragonmike]

Additionally, when remoting onto the rigs with teamviewer, the temperature of the cards is not displayed in the claymore miner window. No idea what's going on there...

Of curiousity... what 570 models?

[dragonmike]

Asus RX 570 Expedition OC

[frostminer]

Asus RX 570 Expedition OC

Interesting.
They have 1x8 pin power connector?

Whats the apx wattage used pr gpu while mining 28mh?


I tested some rx 570itx a couple of pages back.
So tiny and cute... 25mh no mods.

[dragonmike]

97-100W @1V according to gpu-z.

Any idea about my issues?

No sorry..
Im actually having the same problem with some rx 480s... One of the cards insists on doing 3mh less than the rest. And i cant figure out why.

what wattage was you pulling at the wall  or  gpu-z

105-115W.
But those are without any mods.
The cards only have 1x6pin power. Im sure some can push these really low.

Personally im not that concerned with wattage..

just a question, do you divide the power from the PSU right,

make sure you share equal power to card, my be the 3 bad cards use one bank.. not sure don't quote me on that..

EDIT: maybe you must try Wattman or MSI Afterburner to overclock, Claymore does not work for me doing OC setting. that's if you use WINDOWS
