Vertminer/ Low Kh/s

[scesario85]

Hey Everyone,

I'm couple months into to the mining scene here, i started off with ultracoin & now have been mining vertcoin last couple weeks.

Over the last couple months i have learned quite a bit on how to configure verminer.. and probably spent several hour configuring my rigs... however over the last week or so.. i've had quite a battle configuring my cards.. during the first couple weeks i learned.. and at one point manages x amount of khashes per car

290x - 370kh/s
290 - 355kh/s
hd7950 - 305khs/s
270 - 170kh/s

ATM .. this is what i'm getting now.. seems like once i touched the settings on once machine.. it was a downwards spiral with khs dropping on all my cards...

290 - 270khs
270 - 135khs
hd7950 - 180k/hs
290x - havn't bothered trying..

bit in essance a significant drop in KHS...

i usually use 2048 increments from 8192 tc and up
i always used 13 intensity with no issues.. but now i'm only able to run 11.. and struggle to get to 12 i without errors
i've tried 8g.. 16gb ram with no luck..
i'm using btc h81 asrock boards...
my risers.. are some powered usb/non powered/and cable powered.. depending on the power of the cards.. i've run a riser that should work properly

any help would be appreciated/recommendations..

just been a bit fustrated with this ..

Can you copy the whole settings? Easier to spot the error..

[scesario85]

Here is my settings.. this is approx 270khs for my r9 290s

i use to get 355khs..

thx


setx GPU_MAX_ALLOC_PERCENT 200
setx GPU_USE_SYNC_OBJECTS 1
COLOR 0A

vertminer.exe --scrypt-vert -o stratum+tcp://vtc.poolz.net:3333 -u x -p z -v 1 -w 512 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20,-20 --auto-fan --temp-target 85 --temp-overheat 90 --temp-cutoff 95 --gpu-memclock 1250,1250 --gpu-engine 947,947 --thread-concurrency 8192 -d 0,1 --remove-disabled

Just curious, I have been seeing for quite some time for all scrypt N why "setx GPU_MAX_ALLOC_PERCENT 200 " (since gpuc)
Do you really think any gpu will allocate 200% of whatever it is supposed to allocate ?
Passed 100% there isn't any place for improvement that's what 100% means.

Doesn't it mean that GPU will use dynamic memory from RAM?

don't think it would be advantageous since it would slow down the miner (ddr5 against ddr3)

Ive tried 100% or 200% with no change..

Ive tried 100% or 200% with no change..

yeah 200% is useless, stick with 100%, you just need to adjust the core, lower it  a bit, i was able to reach 450 with my old 290

and 290 card use 1 thread, they are not good with -g 2

Are you talking vertcoin or another coin?
