But get only 6-7 h/s for zcash nicehashv0.3a
WHY?????????????

[tjsangariya]

Any one help ??

[tjsangariya]

dual cpu in my workstation with Intel Xeon E5 2650 v2Intel Xeon E5 2650 v2
I get 500h/s on XMR mining with these CPU's
but on Zcash :( :(

[S74nk0]

Those numbers are extremely low for a CPU like that. Does the miner say it is using AVX when running? Did you change -t paramter?

[tjsangariya]

low ...................... Xeon E5 2650 V2 with 16 cores and having 2 CPU in one system
I use -t parameters with more options
-t 6,-t16 and others but still not getting much hashes

[tjsangariya]

Intel i7 6700K having only 8 cores ??

[tjsangariya]

Please see image ??
having AVX but not AVX2

[tjsangariya]

ANY ONE THEIR FOR HELP

[buzztiaan]

how long did you leave it running? it needs like 15-30 minutes to stabilize speed

[tjsangariya]

Only 4-5 minutes running but not in upper image it is only starting of miner.
You mean to say CPU will take time to stable .
OKAY I'll start running it and contact again after one hours......

THANK YOU :)

[buzztiaan]

cool, i'll be watching github

Hi Again ,
after running half an hour it show like this
what is the meaning of

[buzztiaan]

ok,

a) can you post your command line plz
b) can you try closing those ~15 programs you are running while mining, and tell me speed again after ~30 minutes?

[tjsangariya]

I use these on 3 systems
nheqminer.exe -u tjsangariya.tej -p x -t 16 -e 1
nheqminer.exe -u tjsangariya.tej -p x -t 16 -e 0
nheqminer.exe -u tjsangariya.tej -p x -t 16

I am a programmer so I'll work together with this but my other 2 system are free for this and they also have same output

[buzztiaan]

a) you should be using AVX2 -not- AVX1 and -not- SSE2 , if you just remove -e it should autodetect the right one to use (provided you compiled the right one)

b) dont use 16 on 16cores HT , as mentioned in other bugs -and- documention, you should start at the number of -actual cores- for -t (in your case -t 8) and then start upping , -t 9 , -t 10 , -t 11 , to find which -exact- number of threads suits your 16core HT (no, its NOT 16, it never is)

[tjsangariya]

Please see these 2 images having 2 physical processors and their configurations
and suggest the value of -t ??

[tjsangariya]

Hello buzztiaan
Please reply my 10 workstation waiting for mining on Zcash ??

[buzztiaan]

i already told you

dont use 16 on 16cores HT , as mentioned in other bugs -and- documention, you should start at the number of -actual cores- for -t (in your case -t 8) and then start upping , -t 9 , -t 10 , -t 11 , to find which -exact- number of threads suits your 16core HT (no, its NOT 16, it never is)

[buzztiaan]

this isnt 'general help' this is for CODE issues, move to irc channel on freenode, #zcash-mining

[tjsangariya]
