I'm sick to death of my miner crashing. I have six rx 470 8gb sapphire cards and it can run ok for days, then locks up. Then I have to restart it about 10-20 times because I constantly get the message "Ethdcrminer64.exe has stopped working". Then I go into GPUZ and see that one of the cards is not reporting data fully. After 10 restart or so it starts working again, and I get a few more days mining, sometimes less.

What could be causing this? All cards are cool, well ventilated running at 74 degrees contant. this issue is really pissing me off now. All parts are relatively high quality, EVGA power supply etc.

I am running win 10 64 bit

remove and reseat everything. run memtest86 overnight.

all vbios stock?

No I modded them for extra mining capabilities and it worked well for a while but now it's crashing a lot. I am sick to death of the "Dcrethminer64.exe has stopped working" error.

Check gpu-z for cards with Hynix ram lol.

GPUZ reports the ram as 8gb samsung. But sometimes certain bits of data are missing from the gpuz report on one card or another. Can't remember exactly which bits of data, they are usually blank. When you see that you know without doubt claymore is going to crash. But sometimes it still crashes when GPU is reporting everything is OK on all cards. It's a shame because if this carries on I will have to sell up. I just ROI'd thanks to the ethereum price shooting up but I wanted to run it for a year or so. It is taking up so much time now and I cannot nail down the issue(s).

Do you check the PCIE riser? GPU also draw power from motherboard through PCIE.

Well I have unplugged the power connector then plugged it back in, I don't know how else I can check it. What I can't understand is how can the risers be malfunctioning all of a sudden after days of mining? The miner doesn't move, the GPU's are secure. How can they work for days, then fail, then after a few restarts begin working again. There is no logic there unless I am missing something.

happened to me, my risers were v003 (version printed on the pcb near the x16 slot) and after 3-4 months i realised my voltage were spiking to VERY high once in a while (i have hwmonitor running to check status of my video cards) and once in a while it would cause my system to shutdown. i couldn't track it the issue until amorning when i booted the system that one of my rx480 burnt in front of me! sparkles and little firework under the heatsink.
first this happened to me, a chip/solder were burned on the riser. that's how i realised how garbage they were. thrwe them all away and bought v007 a month ago and since then, never saw any voltage spike in hwmonitor.

all i'm saying, to protect your equipment, buy quality parts. (the risers i bought v003 were like 7$ and the v007 i'm getting now are 15$ CAD, worth it and i won't come back home with my house on fire...)
happy mining
