Ok did a dist-upgrade, loaded 17.40 drivers and did the page size modification in grub, but still no difference. I suspect the dist-upgrade maybe didn't load the HWE stack or something.  Probably needs a full rebuild with 16.04.3 and try again.

Hi,
Running a small rig with 2 x RX580 under Ubuntu 16.04.  Just swapped from zcash mining to Eth and noticed my hashrate is very low - around 14MH/s per card under claymore 11.8 with amdgpu-pro 17.20.   I recall there was some issue with HWE and amdgpu-pro and had held back from HWE stack because of that.  Is it now safe to upgrade to HWE/latest kernel and latest x-org and is that likely to fix my hashrate?
Thanks

Getting this message, even after upgrading my wallet yesterday:


Wallet is stuck syncing 7 days behind,  Any clues?

OK found a hack to get it working.  Installed Teamviewer, started graphical desktop session, started miner from separate ssh session (not GUI), disconnected GUI session.  Bit of a pain but best I've found so far.

Yes, I have another rig with a IP KVM attached and that solves the problem there, but I can't get the headless rig to start mining when X is running; it craps out with the good old MIT magic cookie error.  I've tried enabling remote desktop over IP but still no banana.

I have 2 x r9 270x cards in a rig with Ubuntu 14.04 (the old fglrx drivers give much higher performance for those older cards and 14.04 is the last version with fglrx).  I can get it running headless but it isn't reporting temperatures - zecminer reports ADL initialization error.  To get it running headless I have to kill the X server first ("service lightdm stop").  After that it mines fine, but i want to see the temps.  I'm also not clear if it's obeying my config -ttli temp limits because of this.

Thanks.  You are correct re: payouts, it's 0.01ZEC per 5 hours or so.

noob question: a few weeks back my 950H/s setup was getting about 0.1ZEC about every 3 hours on flypool.  These days I am getting only 0.1ZEC every 5-6 hours.  What would cause this?  Increased difficulty?

Thanks.  CPU is a core i7 7700.  Good to know re: PSU.

will a 600W PSU be enough for a Kaby Lake rig running 2 x RX480 (Sapphire Nitro 8GB)?   

I have fixed this with -reindex

Yes I have all of those set in my start.bash.  Mine auto adjusts the intensity back to 3:

Thx.  Have tried again and now getting ~66h/s with my 270x.

Same OS and driver as me, but I have R9 270X and only getting 10h/s.  I think it's all down to needing the exact right OS and driver combo as per Claymore posts.  I think you have to use 15.10 and proprietary AMD driver (Ubuntu 16.40 uses new amdgpu-pro stack).  Can't get any of my other zcash miners to work at all on this set up.

Yes, it was from there.  Still stuck on block 11,001.  Do you want me to send logs or something?

ubuntu 16.04 kernel 4.8 with amdgpu-pro 16.6   amd r9 270x.  getting only 10 s/s.  I know fglrx is recommended for older amd cards, but is 10 s/s expected?  Using default intensity.

Just reinstalled Ubuntu. Re-syncing wallet but goddamn it's taking forever - probably 5 days so far and seems to be stuck around block 11,001.  Running the latest code from git but I'm seeing this statement in the wallet: "Warning: Displayed transactions may not be correct!  You may need to upgrade, or other nodes may need to upgrade."

anyone able to get sgminer compiling under Ubuntu?
