Since V12 it seems to run for 3+ hours and then the computer starts rebooting in 5-15 cycles... and then it ran for 45 minutes and then for over an hour again... weirdness 

Further down this road and the "stability" seemed to get worse.  However, in the end I can't say that it was mainly attributed to v12+ or something else.  I ended up getting several blue screens and then finally doing a reset.  I'm back to an apparent "stable" condition but it has only been an hour. 

Also... I'm running a 3-year old 850 Watt power supply and measuring up to 815 watts with my kill-a-watt at the wall.  That's with 4x 7950's in the rig.  I measure around 100 Watts before the miner turns on so I guess that would average around 175 watts per card.  This is without any undervolting.  I tried undervolting along with this whole stability troubleshooting process and I wasn't successful at all.  I may try again since the reset of Windows 10 OS seems to have made things more stable.

So what does the 850 watt power supply mean anyway?  Should I be able to pull up to 850 at the wall and be fine?  I read elsewhere in this thread (I think) that you could pull upwards of what your power supply is rated for and this gets into the realm of efficiency.  Regardless... I'm jonesing for a new PSU so that I'm not so near the apparent threshold.

The PSU rating is for the DC side (inside the system), not the AC side (wall). So, if the PSU is 90% efficient, it should max out at (100/90) * 850 = 944 watts at the wall.

how much 7950 give and what are the clocks? i get around 261H/s

on mine gigabyte at 1190/1497 +10% power doing around 308 h/s.

i'm at 261.5H@925/1201 @920mV

Claymore, it seems that there's little bug in your program... When I mine with all my 7 rigs, sometime the miner just cannot connect. It says connected to the server and then timeout for 20 seconds. In the version 11 it wasn't doing this and its doing this on all my 7 rigs. After a little while its connecting and mining, but its just that sometime when my rigs reconnect it can take up to 30 minutes.

Please fix this Smiley

If you have the option, you could move a card off that rig and see if stability returns. Just a thought.

I am using linux since v.12 with modded bioses, RX 480's
Rock solid since then, i don't even remember when i did a restart last time

You need to reduce the frequency. The peak power is quite high. There are spikes.

With v.12.1 I have 'Memory can not be read' error. With 12 it is ok. 6*380x/win 8.1/15.12. Any suggestions, please?

is this message from the miner or windows? what intensity? how much system ram? swap file size? psu brand and wattage? any bios tweaks on the cards(s). what are the cards clocks (core/mem)?

Best is to mine @60-70 % of PSU power. There is max eff. Also ZEC mining demands stable PSU, there are power spikes demanding large 12V output electrolyths

anyone notice that 390x show 500 hs for the first 30 sec then it steadily drops.  12.1.  Is that potential or just that the rounds havent avg out.  Most of time it started way short and worked its way up not other way around.. Just wondering

You won't get any working setup using Mesa-LLVM OpenCL implementation Smiley
Use amdgpu-pro opencl/libopencl

Anyone else notice that v12/12.1 is reporting about a 5% higher hashrate than pool(flypool) for polaris based cards?

For example a 470 is reporting 280H/s miner side, and 260H/s poolside average. With 2% fee should be reporting ~275H/s.

Can anyone else on flypool with polaris cards confirm...want to see if its just me or a pool related issue.
