@Phoenixminer: the 5.2a will compatible with the ETCHASH?
We will add support for the new ETC variant of ethash (with reduced DAG size after epoch 390) in the stable version of 5.2, it is not included in 5.2a yet, but there is still at least three weeks before ETC reaches epoch 390.
guys.
all 4gb cards can't mining anymore
Download PhoenixMiner 5.2, add the command-line parameters
-daglim 1 -dagrestart 1 (also may try
-rxboost 1 for additional boost). The hashrate will be lower but that's unavoidable.
It is also important to use auto-tune (do not specify -gt values) because the optimal -gt value may change with each new epoch, and will definitely be different than before. For maximum performance, you can try manually adjusting the -daglim value (the default -daglim 1 corresponds to 4006 MB DAG limit). Some cards will work with higher values like -daglim 4011.
Linux ETH can mine till when ?
Should be ok until epoch 380-383 then you can use -daglim as in Windows.
3 cards
5700XT, 5700, 480 4GB
PhoenixMiner 5.2a ~19 Mhs with -daglim 3967, any greater daglim produces a hashrate drop to 0-1 Mhs
If I use PhoenixMiner for the 5700 and Lolminer with 480 it makes 30,31Mhs
Driver 20.8.1, Windows.
Any suggestion?
Add
-dagrestart 1 and you should be able to use -daglim 4005 to -daglim 4011 depending on the card, which will greatly increase the hashrate. Also,
you must use auto-tune (do not specify -gt values) because the optimal -gt value may change with each new epoch, and will definitely be different than before. Finally, the new -rxboost option (just add
-rxboost 1) may provide some small additional boost.
