25-26mhs currently.

I’m on 19mhs currently on asus p5e deluxe. A week ago it was around 24 on same machine with rx580 4gb gigabyte
Something wrong that I’m sure. But I don’t know what’s wrong.


Are you in Gen3x16?

Gen2 x16

Try to get Gen3x16 and you will see a nice improve...

There is your problem, not enough speed on the PCIE gen 2 port, it's only the same as gen 3 8x... Which isn't good enough for full-speed Zombie I guess.

--4g-alloc-size 4080
Have you got these settings?
It didn't work for me on an old motherboard and the hash rate was the same.
What motherboard are you?
If you fail to configure, then switch to another algorithm. 4GB video cards have very little time left for Ethereum mining.

yes its eth and it should be over 16Mh at least as epoch 404:
https://cryptomining-blog.com/12601-updated-zombie-mode-for-amd-radeon-rx-470-570-and-rx-480-580-4gb-gpus-for-ethereum-mining/



*PS: is there any compute mode in linux to be enabled trough mmpos?

Linux doesnt have compute mode and doesnt need it.  Most likely this is because of the cpu and chipset on the board.  Try swapping it. with a rig that gives full hash.  If so then its a lack of PCIe lanes as this is what slows down Zombie mode.  You need a full 16 pcie lanes to get the full speed.  So google the cpu for how many pcie lanes and then look in mobo manual and see what else uses and shares lanes.

I have a few boards that cant provide the full lanes and others that can.  Those with 16x to the slot achieve full speed the others do not.

Thanks, how much are you getting for rx580 4gb now?

If it's just the one GPU and you're using a monitor with it, that might be tying up some VRAM.
no monitor connected to system, only ssh

In any case, why make a whole new thread? Why not just ask in the lolMiner thread?

because I'm sure its not lolminer problem as I have other rigs working without any problem.

You don't say what algo/coin, so I'm assuming ETH, in which case, the ETH DAG is over 4GB, so your 4GB GPU will be limited by it's VRAM size and thus the low hashrate.

I've 1 asus rx570 4GB on pcie x 16 only and will get ~10MH/s that is very low.
any suggestions?

core is 1100, ram is 2050
