Hi folks, hi claymore,
there still seems to be a couple of bugs in ethdcrminer64. Some of them in dual mode exp+dcr. First of all i must tell that i only work with RX 560 cards.
I have 2GB and 4 GB versions of them and currently only Asus and Sapphire cards. 6 of them are in one rig with a 1000W PSU. All systems running windows
7 prof. 64 bit. Currently i have 3 computer running ethdcrminer64.
The first bug which i want to report is that ethdcrminer64 ever crashes reproducible on start. On all systems! The only way i found to get ethdcrminer64 running is to start zcashminer64 v12.4 before for "initialize" or "flush" the cards. After that ethdcrminer64 running fine, but only once. If i finish it and want to start it again, it crashes. I must start zcashminer64 once (and finish it) to start ethdcrminer64 again. It took me days to find that solution. It also dont help to reboot the system or to turn it off! This behaviour is reproducible on three systems and i tried ethdcrminer64 9.6 until 10.0 and Crimson Relive Edition 17.7.1 until 17.9.1. Two of my systems have currently only ONE RX 560. Dont ask me why, please.
The next bug i want to report is that in my opinion the dual mode (EXP + DCR) is buggy on systems with more than 4 GPUs (Win7 64bit, RX560). I searched over four weeks now for another possible solution but cant find it. I tried to undervolt, i checked possible GPU memory errors (HWInfo64), i checked the psu and the riser cards, i checked the intensity and othe options. I also tested to let the cards alone, dont changed anything on the volt or clock times. I checked the amount of watt for each card and made sure, thats its the same as for solo mode. Nothing helps. The systems with only one card running fine in dual mode. The system with six cards crashes coincidentally if there are more then 4 cards. And it dont really matter if i undervolt the cards or let them alone. It crashes sometimes after 20 minutes, sometimes after 6 hours and most of the times during i sleep :-)
In solo mode EXP the six gpu system works fine.
@claymore
i am ready for bugtesting if you want.
kind regards
