Title: 6x vega 64 miner freezes GPU 0 H/S Post by: BitcoinsGreece on December 31, 2017, 07:07:11 PM I am facing an issue on my farm . I have 6x vega 64 by saphire using cast xmr on nanopool.
Everyday GPU5 goes 0 h/s and the miner freezes. I have played with overdriveNtools P7 from 905 to 980 . p3 memory 1100 or 1050 mhZ and 905-1000mV. Playing on those settings right now which i think they are safe and they issue still occurs. This has been really frustrated for me so any help would be greatly appreciated . https://image.prntscr.com/image/g3I-gC-5TayjKqnVE-d6Tg.png Title: Re: 6x vega 64 miner freezes GPU 0 H/S Post by: xxcsu on December 31, 2017, 09:33:24 PM Your GPU 5 overclocking/undervolting is probaly not right .
each card need to be fine tuned separetly for the best performance. Your GPU 5 might have a lower ASIC quality , try to leave gpu 5 on the factory/default settings , and tuned the card step by step slowly till you can find GPU5 "sweet spot" What is your psu wattage ? Do you have a monitor connected or a dummy plug to GPU5 ?

I'm having the same issue with my rx 580 rig and a 1200w psu, always 1 gpu and usually its the 6th one that stays at 0 sol/s, that said you might wanna try a bit higher wattage psu if you don't plan on modifying the bios settings. so funny how you noobs always seem to overlook the most simplest things. also btw the way if your going to come on here asking question such as the one you've asked, it would be wise for you to post your hardware spec's so everyone that responds could give a better educated answer instead of playing the guessing game with you like some noob fool Title: Re: 6x vega 64 miner freezes GPU 0 H/S Post by: puwaha on December 31, 2017, 10:11:44 PM An even better question... where did you get six Vega 64 GPUs and how much did you pay?

5 of my cards took the same OC settings perfectly and 6th didn't. I had to adjust that one separately. Or you can try lowering the OC across them all until your 5th card starts playing nice.

make sure HBM2 temp is below 70-75C more tips here https://bitcointalk.org/index.php?topic=2549085.msg25986603#msg25986603 Title: Re: 6x vega 64 miner freezes GPU 0 H/S Post by: dagarair on January 02, 2018, 12:15:16 AM on gpu 5 just drop the power but leave everything else alone. I have a 7 card rig vega running for 3 weeks now on cast with no isses and i have power at -22
Title: Re: 6x vega 64 miner freezes GPU 0 H/S Post by: Bakhtra on January 02, 2018, 12:30:38 AM I think its not the voltage issue, but memory issues, make it 1025 or even as low as 950 Mhz. Better get low hashrate than get 0.

I am from Heraklion Crete.. Since i am still newbie i cant pm you. contact me and we could exchange ideas on the rigs and coins farming ;)
