zumbi mode insufficient memory using a gtx 970

[almoutinho]

Hello all, I have download the zumbi feature version 1.19 in order to mine using a gtx 970 4GB GPU.

I have got an "insufficient memory" error message. Does anyone know if the zumbi function is still working?

Command line here: set "POOL=naw-eth.hiveon.net:4444" set "WALLET=0x654066bbE8a170F7c16f150Cd71420f76C2B5a3a.lolMinerWorker_gtx970"lolMiner.exe --devices 1 --algo ETHASH --pool !POOL! --user !WALLET! --4g-alloc-size 4024 --keepfree 8

Here is the console output:

Thank you!

Could you try to change : --4g-alloc-size 4024 --keepfree 8 for --4g-alloc-size 4072,

Also why you only select --devices 1? you can mine with both... but I think that zombie mode in Nvidia is not working perfectly...

I have the same issue with the same graphics card (single GTX 970 4GB). I'm running the _mine_eth4G.bat file.

I tried using default --4g-alloc-size 4024 --keepfree 8 , I also tried using --4g-alloc-size 4024 and --4g-alloc-size 4072 but received the same results:

Any ideas?

That's normal, you cannot mine more ETH with 4Gb cards in Windows... you can still in Linux but a lower speed.

lolMiner's "Zombie Mode" was specifically created for mining (or attemptining it) with 4G cards on windows and linux, I guess that's why he's even here, I've tried many things to get my old 970s to run, no luck so far, the readme states that changing drivers might help, also changing the --keepfree and --4g-alloc-size in the bat might help. Read through the "4G_Windows_Readme.txt", and good luck

May be the problem is that GTX970 has 3.5Gb, not 4gb. https://www.nvidia.com/en-us/geforce/forums/geforce-graphics-cards/5/191814/gtx-970-35gb-vram-issue/

Windows can not mine more ETH with 4Gb Cards... the card is correct, but the Windows driver use some space of that 4Gb, for this reason only 3.5Gb left

[kapi2454]

it only happend in NVidia? I see this on AMD teamredminer, it's suppose to mine with 4Gb

:: These environment variables should be set to for the driver to allow max mem allocation from the gpu(s).
set GPU_MAX_ALLOC_PERCENT=100
set GPU_SINGLE_ALLOC_PERCENT=100
set GPU_MAX_HEAP_SIZE=100
set GPU_USE_SYNC_OBJECTS=1

:: Example batch file for starting teamredminer.  Please fill in all <fields> with the correct values for you.
:: Format for running miner:
::      teamredminer.exe -a <algo> -o stratum+tcp://<pool address>:<pool port> -u <pool username/wallet> -p <pool password>
::
:: Fields:
::      algo - the name of the algorithm to run. E.g. lyra2z, phi2, or cnv8
::      pool address - the host name of the pool stratum or it's IP address. E.g. lux.pickaxe.pro
::      pool port - the port of the pool's stratum to connect to.  E.g. 8332
::      pool username/wallet - For most pools, this is the wallet address you want to mine to.  Some pools require a username
::      pool password - For most pools this can be empty.  For pools using usernames, you may need to provide a password as configured on the pool.

:: Example steps:
:: 1. If you prefer a different pool, change the pool server address.
::
:: 2. Replace the example wallet with your own wallet(!).
::
:: 3. Name your worker by changing "trmtest" to your name of choice after the wallet below.
::
:: 4. You're good to go!

teamredminer.exe -a ethash -o stratum+tcp://eu1.ethermine.org:4444 -u 0x02197021fefa795fec661a45f60e47a6f6605281.trmtest -p x --restart_gpus --uac --eth_4g_max_alloc=374 --eth_epoch=374

As we said before... it is not possible to mine ETH in Windows with 4Gb cards... it doesn't depend on the miner... it is not enough free space in the memory to do it ... it doesn't affect the miner
