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

[adaseb]

I am getting the same issues as everybody here.

I had a rig that only mined ETH, then switched to ZEC for the last few months, and now when I try switching back to ETH, I am getting the -1 error Cannot load DAG onto GPU. All GPUs are 3GB.

Already increased the Pagefile. Same issue.

Go to amd radeon settings and from the preferences >> use restore factory default data
Then go to each card and from the settings clear shedder cache..

The card runs like new. I am thinking that shedder cache leaves something behind from zcash dag

I am using the older 15.12 drivers since these was for a 280X rig.

Dwarfpool down? 

Dwarfpool die?

Dwarfpool die?

How long has it been down for? 

Due to technical maintenance the website will be offline for a short period of time. All your shares are calculated, all pool servers work. The main server will be migrated. Payments will be started as soon as possible.

on my
7990 and 7950 (6&3 gb) i geth OpenCL error -4 (0) - cannot create DAG on GPU
r7 370 (2 gb) i geth OpenCL error - cannot allocate big buffer for DAG. Check readme.txt for possible solutions
but i have a 380 (2gb) this works smoothly

why my r7 370&7990&7950 it does not work anymore Claymore?

They are back now. Everything seems working fine while the site was in maintenance.

what is goot to mine as second coin ?

sia bearly cover energy cost

Decred or Lbry ??

IMHO you should avoid dual mining right now. As you said it simply covers energy increase costs, that being said, you are simply stressing your GPU more without a gain.

I'm currently mining only ETH.
Even though in the last few hours $ gain is dropped because of BTC value drop

You need to set the virtual memory to be 16GB or higher.

hit a strange problem today. my rig with 3x 290's and 1x 280 starts mining ok but after a while the hash rate on all cards drops to 0 and the rig still works with all card hot? i have to hard reboot the rig. it's win 7 64 bit with 15.12 drivers. any ideas please??

Most likely cause is your graphics drivers have got corrupted, you'll need to re-install them.

Miner runs for while, display drivers crashes then Windows 7 recovers and Claymore continues running at 0 hash.

hmmm ive little problem , i cannot understand it , ive 2x rings (one with 3x gpu , and one with 4x gpu ) , in both of them i put my eth adres , and at the end i gave the rig name (ethwallet.pc1 and pc2) after some time the pool only recognized 1 worker , i tried again to rename them and again after some time still 1 worker , ) the 2 x rigs are working fine , i removed now the name and just let ethwallet alone but in pool i only see 88 reported hashrate , in fact ive 203-205 mhs


any help


EDIT : i put rig names in batch  file , not in config file , maybe this is the problem ?

edit2: solved ... i put names in config file and it seems fine now

is already set a value greater than 16 gb

I mined ETH, then switched to ZEC for the last 2 months, and now when I try switching back to ETH does not work anymore

Someone has found the solution to this problem?

I dont think you can mine ETH or ETC any more with 2gb cards. DAG too big.

To verify, try EXP

yes you can.

my 2 gb 380 nitro is still mining eth in a win7 rig. it only will mine in a 3 or more card rig though.

may depend on card position, manufacturer and/or driver version.

Weird.
All my rigs with 2gb cards cant create DAG.. no matter what miner i use.
They do mine EXP fine tho... but not ETH/ETC


Card position shouldnt affect dag size

i wouldnt think so either.

it wont create dag when its 2nd gpu in 2 gpu system. but it will as 3rd/4th in 3/4 cards system. at least under win7.

only thing i can think of is win7 reserves some part of a 2nd cards memory even if not being used for display. but will ignore any cards after that.

doesnt make much sense to me either but as long as it mines im cool with it.

But how about 3 & 6 GB card 7950&7990 still OpenCL error -4 (0) - cannot create DAG on GPU

I tried both 7.4 and older versions .... same result

did you updated your graphic drivers ?
