CUDA Error in CudaProgram.cu:465 : an illegal memory access was encountered (700)

Hello everybody,
I have one rig with 6 cards (3x1070 + 3x0170ti)
I decide to move from windows to HiveOS. I install HiveOS on usb flash memory 32GB size.
I do basic setup at rig.config file, and basic setup on hiveos.farm portal.
when i boot rig from HiveOS flash it starts, detect all cards, displays theirs characteristics well but…
When i start PhoneixMiner without any additional commands it start mining but after couple minutes (5-7min). Miner restarts and also that reboot rig.
GPUs are OC with same settings as i setup on windows. Also i try without OC and get same error.
Miner reports CUDA Error.
"GPU3 CUDA error in CudaProgram.cu:465 : an illegal memory access was encountered (700)
GPU3 GPU3 search error: an illegal memory access was encountered
wdog Fatal error detected. Restarting."
This msg was logged for all GPUs.
I have trouble on windows where i resolve this error making page file bigger (sized page file by formula 68GB60/) and after that i have no problem on windows.
Also I find that HiveOS don’t use swap for mining.
Please can anyone help about this error.
Thanks in advance.

I get the same, mostly on my GPU 2 which is a Nvidia GTX 1080 Founder’s Edition. Looks like that card causes all the other to crash the same way.

hello me too

GPU2 search error: an illegal memory access was encountered
CUDA error in CudaProgram.cu:465 : an illegal memory access was encountered (700)

Any help please ??

Mem clock is awfully high. I would set the mem at 1800 and increase incrementally from there. Not all cards will take the same OC even when the cards are the exact same brand and version. My 3080’s would not take a mem clock of 2600. Why do you have the 3070 mem so high? For the OC you have you are really light on power.
My OC for ZOTAC Trinity 3080
core -200
mem +2000

98MH

core -200
mem +1800

Hey! I only use a presets on hive! The problem isn’t with 3070.

Watch those. many are bogus, and I have had major issues when I first started by using them I do all my OC settings myself. All cards are not the same, it is the silicon lottery with how fast the memory on one card vs the other regardless of being the same brand and model.

Okay, clear with this. Maybe u can recommend me another fine miner for nvidia? Which u use?

I use Phoenix and LOL as I run mixed rigs. I started having the illegal memory errors over the past several days. After much messing around I found stability with the 3080 by not under underclocking the cpu. I had them at -200 & -100. By changing them to 0 for cpu it all started smoothing out.

So, it’s my results for a last 23hrs. I’m starting use NBMiner 36.1 and no more problem.

I am still having intermittent issues with this. I did a hive replace and loaded the beta version last night. I updated the NVIDIA drivers and it ran solid for 12 hours. I thought I had it fixed until this morning when the rig went offline with no errors from the miner. I am running out of ideas on this one. I also have not seen anyone who found a solution to this. I have been all over reddit, nicehash etc. I am to the place where I think I am going to put a schedule in for the rig to restart every 6 hours so it stays up. Hard to make any money when your worker is down.
I am going to change to NB and see what happens. I will continue to give feedback as I go along.
You might also follow this string.

Updated to NB and I have not had an issue, 4 hours without issue! Thank you for the advice!!

Try to use 009S risers revision. It’s good for me.
Like this one Amazon.com

Wellp… I’m ffeling all your solutions out here, but –

  • I had my 3070 set with core - 200. I set it to 0. Same hashrates, 60MH… but still that error.
  • had a 1080 Founder’s Ed. in the rig, was overheating, so I took it out… still no go.
  • replaced the RAM, no change.
  • I reset every power line I have in that rig and made sure each riser was connected to the power line that was in turn powering its GPU. Nada.
  • Tried mining with T-Rex, NBMiner, but I crash the same way.

Every dam thing I’ve done so far has led nowhere. My rig doesn’t last more than 20 mins while mining. All of a sudden, kaboom,the entire thing reboots, and it’s always this damn CUDAProgram.cu:465 error.

Things I think may be happening:

  • not enough RAM (I have 4G of 1333 DDR3)
  • risers are not stable (008S series with ONLY SATA connectors, but they are getting replaced within 2 weeks)
  • operating HiveOS directly from the USB key without a SSD… but this I doubt

So does ANYONE know how this can be resolved? No stabiliy means less cash for me, and I don’t like that.
HELP!

I have this problem only on RTX3080 gpus. no solution yet.

Please provide your config screen.

no need. I wasn’t too keen disconnecting the rig and restarting it 1 card at a time, but I finally did it. Turns out it was my most profitable card that was a little too overclocked. After I took time and restarted and ramped up the memory overclocking SLOWLY, I now have a nice green horizontal line. Thanks for all your help.

Hi friends
I have a problem with my card (1060 Zotac)! after 2 hour of working it stop mining and i get this error:
“GPU1 CUDA error in CudaProgram.cu:465 : an illegal memory access was encountered (700)”
can tell me what is problem? I try with high or low memory clock but the same result get!

Since upgrading I have had this error now 2 times, and one time it went it lasted 24hrs after starting the miner, the second time was 12 hrs. This is seems like an issue with phoenix miner and the new update, but now i see its happening with other miners as well, 5.5c
