Is it normal if at the moment i use another programm in windows while mining with vertminer hashrate goes heavily down ?
If i open a wallet for example, hashrate drops down to 15% of total. It takes minimum one minute to come back again and does
not reach 100 % of old value.
I tryed to mine DRK with sgminer and it doens`t make any difference in hashrate if i use other programms or not.
yeah that is normal.. vertminer cgminer etc all require a bit of cpu power available at all times to work mining..
so if you all a of a sudden max out your cpu you should see a drop in hash rate until you free up the cpu again.
the cpu has to orchestrate the work like a conductor standing in front of a band.. he is not doing much but if you screw with him the band goes to hell lol
like the cpu is what is feeding the work to the gpu so if it has any delay in sending work then work speed slows down. make sense ?
i use vertminer myself with 1 gpu.. a Powercolor 7950 and i occasionally mine with my cpu on and off too or do video encoding etc
and i have different computers with different cpu's and it doesn't matter which one i use they all follow the same rules or problems etc.
my main machine is an i7 with 4 cores and 8 threads so if i use the cpu i make sure to leave 2 threads free for the GPU miner.
(so i would run the cpu vertminer with 6 threads via commandline) while gpu mining at the same time.
On another computer i have.. an nvidia card mining VTC with cudaminer with a Core 2 Duo e7500 and that is only 2 cores / 2 threads
and if use up the the cores on that cpu it slows my nvidia miner down too. I rarely ever cpu mine on that one because
it's not worth slowing down the faster nvidia gpu miner.. so yeah it's normal
Thanks for your detailed answer. I have noticed that the wallets only use much CPU power while they are not synched. After the are synched
and still open and stay synched it does not effect my mining power.
Oh yeah wallets are notorious at sapping CPU power maxing it out (until they are synced)
It's normal and some are way worse than others depending on the coin.. some people may not know that.
Still mining away using cgwatcher and Vertminer 0.5.2
Here is my whole bat file i use for my Powercolor 7950 in case people want to see it ?
Notice work size 256 ? i think the miner is hard coded at that value so if you try 512 or 128 it won't work..
You can see this by looking at the *.bin file name.. maybe some other miner version can let you change that i don't know.
And the second pool i have listed is a fall back if the main one goes down and that is pointed at my VTC wallet with a conf i made for the wallet for solo mining.
obviously i would have to have the wallet on and synced at all times to do solo mining with Vertminer though (if the main pool goes down)
Also notice a key setting to experiment with here is GPU Threads

Also here is the contents of my bat file showing how to specify a .Conf config file..
I have no idea if i used the GPU map feature correctly though, i want to skip my integrated Intel 4770k Haswell graphics chip and only mine with my Radeon.
Note: you do not have to specify the full path like below.. cgwatcher changed my bat file and did that.
C:\Miners\vertminer-0.5.2\cgminer.exe --gpu-map 2:1,1:2 --config C:\Miners\vertminer-0.5.2\cgminer.conf
result obtained is:
