OCTANe crashes on RTX Studio drivers

Hi guys

Please can someone form OTOY chime in and tell us which drivers we should use to make Octane stable/renders properly nowdays ?

I had 431.86 and that driver was great for octane 4.05 and octane 2019.1.x, all was working fine but since octane 2020.XB1 and XB2 OTOY suggest moving to 435.80 or higher Studio drivers or otherwise RTX is not used/working.

OK, good i installed 441.66 SD and on short scenes all seem to be good when frames are rendering between 2-3 minutes but as soon as i switch to 20 minutes renders (bigger resolution, more samples) my octane always crashes on 2nd frame of rendering. It renders frame 0 in 18 minutes and then it starts next frame for few minutes and then crash - RENDER FAILURE with that awful message "CUDA error 700 on device 2: an illegal memory access was encountered". It does it every time (on any of my GPUs and then for all 4 GPUs in a row), first frame is rendered fine (first as firs tin line not exactly frame 001, I can render frame 2 and then frame 3 will fail, or i can render frame 99 and then frame 100 will fail etc. etc..). also it's not scene related, happens on any medium sized scene (i have more than 6GB VRAM free and 100GB System ram free when rendering it). Nor is my computer related (tested on my render-slave also same error and also i know another user with same issues so it's either OCTANE BUG or octane incompatibility with Nvidia drivers)

I tried 441.66 and i tried downgrade to 441.28 and 441.12 now and still same problem. I tried octane v4.05, v2019.1.5 and v2020.XB2 and v 4.05 and 2019.1 render one frame and fail on second but 2020.XB2 don't even finish first frame and fail sooner around 14-15 minutes (on 20 minutes render).

So i payed 1050EUR + TAX to get my 3 licenses up to speed at Octane 2020 so i can use RTX (which was suppose dot be in 2019.2 at first) and i need to babysit computer and restart rendering one by one frame all the time and cant' even use 2020 in production ???

Can you please stop adding new features and sort this stability thing once for all and KILL that "illegal memory..." BUG finally ?
I don't know how but maybe you should certified single stable driver which works with OCTANE, Test it together with Nvidia or whatever just make the damn thing stable finally :).

Here is my log file (if that helps?) from today's 7th crash in a row.

Thanks.

And i just tried to use latest Game drivers 441.87 WHQL Game drivers and frame 001 rendered in 28 minutes, frame 002 was rendering for additional 19 minutes and then it just stopped with new error, CUDA 716 this time :(.

00:47:43 (2863.84) * OCTANE API MSG: CUDA error 716 on device 0: misaligned address
00:47:43 (2863.84) * OCTANE API MSG: -> could not get memory info
00:47:43 (2863.84) * OCTANE API MSG: CUDA error 716 on device 2: misaligned address
00:47:43 (2863.84) * OCTANE API MSG: -> could not get memory info

Hi Lewis,

At least you can render a single frame with RTX!
My bigger scenes (lots of textures/geometry) won't even render a single frame!
I am at Octane 2019 WITH driver 431 so I can render at least my current projects.

I (and others) reported this already at day one of Octane 2020, but no solutions came up.
My superduper 2080ti's (multiple) are not living up to their potential with Octane now.

So I agree with you, please kill this illegal memory bug!
Bugs the hell out of me.

Thanks!
