I found something very interesting while poking around the x10 file structures.
I found these 2 lines:
poolAdd({url:'stratum+tcp://nist5.mine.zpool.ca:3833',pass:'x11=1,quark=1,qubit=1,groestl=1,nist5=1',priority:'6',algo:'nist5',extranonce:true});
poolAdd({url:'stratum+tcp://groestl.mine.zpool.ca:5333',pass:'x11=1,quark=1,qubit=1,groestl=1,nist5=1',priority:'5',algo:'groestl',extranonce:true});
So I am guessing either the 2 new algos are nist5 and groestl, or they originally had nist5 and groestl and decided to change the algos to skein and myr-groestl.
I also found this line:
sudo mv sgminer_300MHz_fix_NoHW /opt/scripta/bin/sgminer
So I am assuming they have their own custom sgminer with a fixed clock rate so there goes the overclocking dream.
Guess someone at Baikal didn't remove all their traces. Now I wonder how would we get nist5 and groestl back on there. LOL.
Baikal is indeed using a custom sgminer.
I attempted to decompile the sgminer, but didn't get far. However I did find this in the code:
I haven't tested the clock option, but I think it might just be the lower limit at which the miner reboots if the clock speed falls down.
