Quick info for upcoming ETC hardfork (in few hours):

lolMiner 1.16 (and the versions before) is ready to support the fork that will happen on block 11 700 000.
To automatically switch over to the new scheme use --algo ETCHASH when you run the miner manually.

If you are using a mining OS like HiveOS, please select ETC or ETCHASH as parameter in your flight sheet.
In case you can not change it or are uncertain you alternatively can add --enable-ecip1099 to your extra user configuration parameters.

Note that ETCHASH = ETHASH + ECIP 1099, so the result will be the same and you can safely add  --enable-ecip1099 to any working configuration without damaging it.


All of this also applies when you mine ETC+ZIL! In this case just configure for ETC mining - the miner will recognize the ZIL mining and switch to ETHASH for that time and switch back to ETCHASH once Zil mining is over.
Have fun with the fork.

It is Windows 10, not Linux.

Which driver version you are on and have you checked other values for --keepfree and --4G-alloc-size like described in the 4G_Windows_Readme.txt?


And another question, the new Octopus algo is promising at nVidia, is there a plan to implement these in your miner for AMD?

I answered about this one few pages earlier. Octupus is extremely compute heavy, in particular multiplication of two 32 bit numbers to a 64 bit one. While Turing and Ampere can do this operation using only one clock cycle, the AMDs need 4 (professional cards & Vii) to 8 clock cycles. Also Turning and Ampere can do easier operations in parallel. Therefore the expected performance on AMD is rather ... horrible. I did some tests but was way away from the two modern Nvidia numbers here. It might be that big navi can do better, but the full instruction set for this architecture is not yet released. Waiting for that if this allows some quicker approach.
