Hi, i have a few problems with my Rig

The rig have:

H110 Pro BTC+ ASRock (P1.50 02/26/2018)
CPU G3900 @ 2.80GHz AES
ATA PNY CS900 240GB 240GB
PSU Server 2450W + PSU 750W Thermaltake 80 Plus Bronze
13x RTX 3070 Nvidia

The first problem
1- When i try to mine with the 12 and 13 GPUs appear this message:
"TREX: Cant find nonce with device id=11 GPU#11 Cuda exception in synchronize 51 , unsepcified lauch failure, try to reduce overclock to stabilize GPU state…

I try changing the Riser, chage the conector of PCIe of the mother, trying with another PSU, set the stock settings

Second problem:
2- "TREX: Cant find nonce with device id=00 GPU#00 Cuda exception in set busy 85 unspecified launch failure…

Third problem:
3- cant find 999 gpu trex mining

Some one can help me?

Hi, did you solve it?

I’m facing same problem but when connecting the 10th GPU.
Suddenly, T-rex shows your first msg for GPU5 and restarts. This repeats no matter what I do (raisers, cables, splitters, etc). Removing OC didn’t work.

Hi
I add more ram, i was using 4GB DDR4 then i put 4gb more and the problem was solved

4

I have 6 rtx 3080 but have the same code error

Can’t find nonce with device [ID=4, GPU #4], cuda exception in [synchronize, 52], CUDA_ERROR_LAUNCH_FAILED, try to reduce overclock to stabilize
GPU state

Have 8 gb ddr 4

Getting the same error on one of my 1080’s. Has anyone found the fix for this yet?

Getting the same thing on one of my 1080’s too. Using t-rex and -mt 2, if i put in -mt 0 it works again. Didn’t have this problem before.

Can’t find nonce with device [ID=3, GPU #3], cuda exception in [synchronize, 52], CUDA_ERROR_LAUNCH_FAILED, try to reduce overclock to stabilize GPU state

same problem ? tried to adjust gpu 3 nothing is working… did update nvidia drivers to 64.80 but even that didnt do anything

8

Today i enabled -mt 2 and the error is gone! I didn’t change a thing, i did the change in the IOS App. I don’t get why i had this error. I tried rebooting, updating everything etc. But it works now again. :open_mouth:

Could you please tell me what do you mean by enabaling -mt2> Blockquote

I experience the same error over and lver again… sometimes after 1h … sometimes after 2days- miner is restarting.

hello, i had the same problem. My kit is the 11x3070 (Dell) + Asrock H110 Pro BTC motherboard + 8gb RAM.

The problem with the miner was like above every one, be it t-rex, nbminer, phoenix, etc. The problem was solved by adding an additional RAM chip. Now I have 12GB of framework and 24 hours of stable work with normal OC. 61 mhs per card.

Sweetpayn,

goofee, is referencing memory-tweaks. This is added in the “Extra config arguments:” under setup miner config. Depending on what mining software you are using the syntax will be slightly different. I am using T-rex right now syntax is “mt”: X. The X is the numbers from 1 to 6 depending on what memory tweak you want to apply.

Happy mining!

so what we must to do to solve it ?

now having this same issue with 12 x 3070s. been running absolutely fine until i blew a ZSX card. just added a 3rd PSU and replaced the card and spread out the GPUs across 3 PSU instead of 2. Now when I boot, cards mine for maybe a minute, then start throwing these errors. Note I have disabled OC on all cards, rebooted the whole system, the -mt parameter suggested above is only for 10xx cards and doesn’t do anything on 30xx cards, I have 8GB of system memory. I’m stumped and I hate that I’ve spent 8 hours working on this rig today and am going to bed with 12 cards down.

it APPEARS the 3rd PSU may be bad. I powered it off and the 7 remaining cards are mining absolutely fine. I had a replacement PSU next day shipped, so should be able to confirm tomorrow.

Did anybodi solved problem with this

I have same problem too. These are my last logs before rig goes offline:
