hash different? same card but different hash?

[ccexperiment]

hello all,

i have 2 MSI GFORCE GTX 1050TI 4GB.
They are all the same and OC settings cloned with afterburner

BUT ....

when i mine hashrate a different ... why?

ETH - Total Speed: 25.801 Mh/s, Total Shares: 0, Rejected: 0, Time: 00:00
ETH: GPU0 14.138 Mh/s, GPU1 11.662 Mh/s
DCR - Total Speed: 430.011 Mh/s, Total Shares: 1, Rejected: 0
DCR: GPU0 235.639 Mh/s, GPU1 194.372 Mh/s

GPU0 has same result as when he's alone

do you have any idea?


thank you

go to gpuz and check the memory vendor of the gpus

Well, this is really tough question...
If the cards are the same and they are working on the same clocks for memory and core ( which is very important with ETH mining) then the only difference should be about timing in memory of the second card.
I think they are much worth then the first one. Try set different speed of memory for both cards and check what would happen?

What happens when you swap the cards PCIe slots?

found the issue ...

memory are the same, manufacture date, ... everything the same BUT ...
for unknow reason GPU1 is not accepting the same OC as the GPU 0 ...

i have lowered little bit OC and for now seems to be ok
