you suggest changing the intensity?

No, i suggest reading the 1.8.8 release notes Smiley

Code:
 No more --gpureorder, device ordering by bus id is now the default/only display mode [NOTE: if you are using gpu_conf or --cgpuid, please run --listdevices to check if you are using the right deviceid!]
oh you mean setup the config file as this examples shows.
{
"cryptonight_type" : "normalv4",
"intensity" : 0,
"double_threads" : true,
"gpu_conf" :
[
   {
     "id" : 0,
     "intensity" : 112,
     "worksize" : 16,
     "threads" : 2,
     "tweak_profile" : 3
   },
   {
     "id" : 1,
     "intensity" : 112,
     "worksize" : 16,
     "threads" : 2,
     "tweak_profile" : 4
   },
   {
     "id" : 2,
     "intensity" : 111,
     "worksize" : 16,
     "threads" : 2,
     "tweak_profile" : 4
   },
   {
     "id" : 3,
     "intensity" : 110,
     "worksize" : 16,
     "threads" : 2,
     "tweak_profile" : 5
   }

V1.8.8
- Reduced CPU usage up to ~50%, can be noticed on algos with small scratchpad
- User is now informed about tweaking status on the screen too, not just in log
- No more --gpureorder, device ordering by bus id is now the default/only display mode
- Added parameter --watchdogrounds , which controls after how many rounds will watchdog trigger
- min_rig_speed_duration default is 1 minute now, because of the new --watchdogrounds parameter
- Fixed a few cosmetical things on web stats


+ If not using 'old_mode', on weak CPU's the cpu usage could go boom on algos with small scratchpad (UPX2, Turtle). In this version i managed to lower the cpu usage up to ~50%.
This also brings a small hashrate increase for RX cards on UPX2 as a side effect Smiley

+ The default (and only) device ordering mode from now on is ascending by bus id, as it is in OverdriveNTool. Parameter --gpureorder is removed.

+ Because of some trouble with gpu/min_rig_speed watchdog and kernel precompilation on CN/R (V4), a new parameter --watchdogrounds was added, so you can control after how many check-rounds will the watchdog trigger.
The GPU crash watchdog has a fixed interval of 30 seconds = 1 round. That means it will trigger miner restart only after --watchdogrounds * 30 sec (default number of rounds is 5).
5 * 30 = 150 sec ~ 2.5 minutes. If gpu crashes and can't recover for 2.5 minutes, the miner will trigger the restart action.

min_rig_speed parameter is also affected by --watchdogrounds from now on. The 'min_rig_speed_duration' parameter default value is now 60 sec, this is the value as the above for the gpu crash watchdog, except that you can change the value of this to anything >= 30 sec.
Taking the default value of 60 seconds and 5 rounds, it is 5 * 60 = 300 sec = 5 minute, that means if for 5 minutes the 'min_rig_speed' < total hashing speed, then it will trigger miner restart.


hi, my vega 64 CN-R algo without tweaking Hashrate dropped from 2040 to 1970 moving from 187 to 188 , same config and same pool file and same coin. interesting is that my vega 56 didnt get affected. Im running low voltage settings on both cards (at the most stable possible setting)

Im running into the same issue. what did you do to fix?

Read back a few posts
you suggest changing the intensity?
