Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[Botnake]

@Claymore
Rig 6xR9 390 1150/1500

v.1.0 - v.8.0 - 0 crashes for all the time.

v.9.0/9.1 – crashes each 10-15 min, various GPUs. (any -i value)

Something is wrong with this version.
Rollback on v.8 returns stability.

Again and again.
Problems can be:
1. PSU  wattage load
2. PSU ripple suppression
3. PSU voltage regulation at different load variations
4. Bad risers and other cables. (Least likely if still working in other versions)
5. Incorrectly configuring windows

Answer to myself, maybe be helpful for someone.

The problem was in Radeon driver. If all of previous versions worked fine with v. 16.10 (including Claymore's ethereum miner), the version 9/9.1 in some configurations (including my 6xR9 390) works only* with drivers v. 15.12.
For sporting interest, made few clean re-installation to purity of the findings.

310 h/s from 1 GPU (-i 8 )  now.

2. Tips in 1-5 - utter nonsense and completely useless demagoguery. Only misleads readers.

So 15.12 is more stable?

since all the stink about flypool payouts, which feels like promotional effort on the part of dwarfpool or whatever...

...been mining there since day 1, with a few days on nanopool due to constant crashing of some early genoils miner
So far it seems fair to me, as I'm able to get what my daily target numbers are.
I'm pointing my rigs to different algos to get the best results.
The current situation is well balanced: dagger-hashimoto, equihash and cryptonight are very neatly aligned so the final decision could be your own vision of the coin's future.

Now will do focused check of zec on flypool and report back here.

yes they had a web server problem but shares were still being collected and were recalculated correctly.  I have been allocated what I would expected to earn so I do not see a problem with staying on the pool

Their hash rate is climbing quickly. I certainly will keep on dwarfpool as it's considerably more profit even through the hiccups. Set and forget.

Only if you use SSL.

So 15.12 is more stable?

Yes, 15.12 works perfectly. 0 crashes on win 10.

Dwarfpool EU server again @ 3000ms+

well if you have problems with dwarf eu server just change the server to US server.... worked well for mee this morning, even with 200-250 ms connection of shares......

same advice in future, just change the server, dont have to change the pool....

thanks friend.

What do you think of nanopool?

Flypool theft my actions.

3 hours ago, after the dwarf problem was sorted out, I set miner back to EU server and the connection was OK - 78ms.
Now, half hour ago, I've checked it and it's again @ 3000ms+.
It will be nice if we would have a switch in CM to change pools automatically depending on the connection lag.

@Claymore,
looks like something strange there...  v9.1 (and maybe other versions - not tested) send shares below target after diff change (vardiff). So all of these shares rejected by pool. Why new diff ignored?  Can you please check?  I can be wrong and I have limited debug data - not sure if this happens always or only sometimes at some conditions.

I have no problem with delay on dwarfpool, using eu server.

I have no problem with delay on dwarfpool, using eu server.

well noticed the delays 30 min ago, up to 6000-7000 ms but accepted...

Now it looks normal, 47-93 ms....
