Sounds like a power issue. Check your risers power distribution. Preferably one riser on a single sata cable but we know it`s not always possible. Never power more than two risers on single sata cable.
My calculations your rig pulls about 800watts, that is high for only a 1000watt psu.

Don't overclock the memory clock too much, running at a high memory clock can bring memory errors in future, meaning memory loose due to high memory temp, the lower the temp the better, the highest I've seen my graphic cards go is 60°C and I tend to keep it this way
Yup, what he said. plus my post
Rule of thumb, I have been mining for almost 4 years with 120 plus cards. Lot`s of expensive lessons learnt!
1. Power supply, never push your power supply to it`s limit. Sweet spot is around 60% utilization.
2. Dust is a card killer, make sure you maintain dust as well as you can
3. Temperatures, place your rigs in a well ventilated room. Try remove the heat generated by the cards (Extractor fan).
4. Don`t be an IDIOT and OC your cards to the max. Loads of people are chasing hashrate instead of finding a sweet spot.. pushing a card to just under the point where it crashes is really idiotic. Your card might cope for a couple of months but it will die on you after a while when pushed it to the max.

Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly

Who can share the best timings for Vega 56 (samsung) for Eth, please.
Download TRM and check the ETHASH GENERAL TUNING txt. They have a good guideline to start with.
I have also noticed TRM gives a higher ETH hashrate with Vega`s in general, plus you can do the mem tune for some additional hash.
Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly
Got one Hynix Vega 56 running with RCDRD 12, RC 35, tREF 15600 and 930/900 memory for 50,5 Mh/s and another RCDRD 14, RC 37, tREF 7200 and 930/900 memory for 48,5 Mh/s.
Thanks, will give a shot. Just to clarify your OC. Is it memory 930mhz and 900mv or core 930 and mem 900?
With V64 mod?
Re: AMD Mem Tweak XL - Read/modify timings/pp/straps on the fly
would someone please be able to help me out with some vega 64 timings and clocks and maybe ppt tables to get power usage below 200W at wall? been getting 48mh @200w from wall from each card, i imagine i can do better.
Settings in pic run ~168w/GPU including idle ATW (120v, 1600 plat PSU). amdmemtweak params are --RAS 30 --RCDRD 14 --RCDWR 6 --RC 44 --RP 12 --REF 11700 --RRDL 4
Thanks mate ill give them a run. im on windows though and dont think i can get voltages down that low without powerplay tables? think its capped at 900mv.
You can use ODNT to easily create a PPT similar to my clocks/voltages listed on the right. Only difference is that you may need to use mem P2 set to 1028 (and lock out P3), in order to take advantage of the power savings of a reduced SOC clock.
Btw, if you really want to get crazy, there's been a lot of noise about flashing a 64 w/ a 56 BIOS (yes, the reverse of what most people have been doing) to get higher hashrates at lower power. Not sure which models this actually works for tho, and haven't tried it myself... yet.
i'm getting 54Mh (samsung) and 50MH (hynix). 930W on the wall for 6 vegas (all flashed 56). 900W on the wall, plat PSU.
Can u share your timings on the samsung vegas.
thanks
Please share your Hynix timings, it would be greatly appreciated.
Re: AMD Mem Tweak - Read/modify mem timings on the fly - [Vega Friendly] [Win/Linux]
If you're lucky, you might find a Vega 64 vbios for that same card (if they made em both 56 & 64), which is unique.. not much out there, Pulse, only 56 afaik.
That however doesn't mean they're crappy, i've got a Sapphire Pulse with Hynix memory and it's running smooth at 47~Mh (memory at 975).
Got a Samsung Vega56 too and hits 48+Mh..
The thing is, they only have 6 SOC states, so it gets auto forced into a lower memory state (800MH), you can see this in the tool..
Vega 64 has 8 SOC states, therefor it goes to the highest memory state (1000Mh).
Can you explain this, i'm interested in getting this hasrates and also any optimizations for my wonderfull 56s Pulse nano watercooled???
What PPT/timing to use for "all-cryptos-round config" with Vega56-113-376XL-UO2-180315.rom
More specifcly what timings for ETH?
I'm ready to share all i have (PPT, Monitoring...) and i have a lot, so if you guys are interested... 975mem on our tinies nano pcb+hynix mem is that a joke?
Just need to set to maximum "sclk 5" right?!
My rocm-smi PPT, Ubuntu 18.04, AMDGPU-Pro 19.30:
I hit 42.6 with Hynix and 44.9 with samsung stock timing!
You can actually go 50 MHs+ on a vega 56 with Hynix. This one can go 52 MHs+ at 1090+ core.

What is your Hynix timings please?
I have been browsing the forum but havent seen the actual timings to achieve 50MHs.
Will lol miner be getting an update to mine with amd rx5700xt
0.8.8 already works for 5700, for cuckatoo31, cuckarood29, equihash192, and equihash144. Doesn't hash from equihash125.
Any hashrate results?
Re: [ANN] [POW] FUNCOIN NETWORK - educational platform for web 3.0 developers
Can someone confirm that this actually working?
Hi @doktor83,
I am not sure if this would interest you. But have look out at Raptoreum coin. They currently on Testnet and should go to mainet soon.
Might be something you can develop for CPU minable coin and possible GPU as well.
