Hello,
got some Asus p106-100 gpus but they the hash drops after 2-3 mins from 25 hash to 13 hash on eth. Doesnt matter what client i use for eth. ( claymore, ethminer ) On ethminer its worst ( drops to 0 hash )
İ try with overlock and without. Whats is your experience with that GPU?
I also have similar problems…
Does your problem finally solved?
nope
still trying to find a solution .
Seem like there is a problem with the stratum …
Got on the same network over 15 Rigs with 12x gtx 1070 on eth pools ( miningpoolhub and ethermine) They work without any problem but the P106-100 works strange.
First it starts with a masive increase of hashrate ( see the pic . 1 P106 works with 120+mh ) after that the stratum ms …
On Claymore its the same … After 10-15 shares the hashrate drops masive and then it shows 0 hash.
The gtx 1070 and P106 got the same other Rigparts 
Biostar TB250 BTC pro
G4400 cpu
8 gb ram
120 gb sdd
Same riser
same P106 rig works perfect on other algos . ( ccminer etc…)
I have bought 94 pcs P106. Testing with one rig now. I have the same problem. Did you find solution ? I use hiveon etc pool and eth miner.
