RC is crashing my PC, but not my laptop. Both are new and high spec (see below). PC crashes completely and restarts on medium alignment settings, 16bit HDR images (tiff). Drivers all up to date.

Any help appreciated!

Laptop:
-Intel Core i9-13900H 14-Core (24M Cache up to 5.4 GHz)
-NVIDIA GeForce RTX 3050 4GB GDDR6 VRAM (95W TGP)
-64GB DDR4 3200MHZ (2 x 32GB)
-4TB - PCIe 4.0 - PNY CS2241 NVMe M.2 SSD
-2TB - PCIe 3.0 - PNY CS1031 NVMe M.2 SSD

PC:
-Intel Core i9 13900K 24 Core LGA 1700 3GHz Unlocked CPU Processor
-2 x NVIDIA Quadro RTX A4500 20GB
-2 x Kingston FURY Beast RGB 32GB (2x 16GB) DDR5 5200MHz Memory
-ASUS ROG MAXIMUS Z790 HERO LGA 1700 ATX Motherboard
-Seagate ST8000DM004 8TB BarraCuda 3.5"SATA3 Desktop Hard Drive
-Samsung 980 Pro 2TB PCIe 4.0 NVMe M.2 SSD - MZ-V8P2T0BW

Hi bajp2019,
what kind of crash do you have? Is there some error message?
What are your alignment settings and how many images are you trying to align?

Hi there,

No error message, just total computer crash.

33 images, tiff ~266mb each, 16bit converted to 8bit on import to RC.

PC Settings:
max features per mpx: 50,000
max features per image: 10,000
image overlap: low
image downscale factor: 1
max feature reprojection error: 2.00000

Laptop settings (no crash)
max features per mpx: 10,000
max features per image: 40,000
image overlap: low
image downscale factor: 2
max feature reprojection error: 2.00000

update: just used these settings for successful alignment:

max features per mpx: 10,000
max features per image: 40,000
image overlap: low
image downscale factor: 2
max feature reprojection error: 2.00000

PC totally crashed on Calculate Model step (normal detail, default settings) :frowning:

Hi bajp2019,
this second crash was also without any error? Just crash?
Is this also happening for other dataset? Is it possible to compute Preview model?
Probably there could be a problem with number of cores. For example you have 24 cores * 2 hyperthreading * 4 gb of ram per thread = 192GB RAM for a good performance in high compute calculation. Otherwise it is swapped on C disc.
Could you test disabling some of your cores or disabling hyperthreading in your BIOS? And turn the reconstruction test again?
One more thing I would try is to manually set windows swap to 150% of your current RAM so you would have 32GB+ 150% on windows swap (keep in mind to use an SSD disk for that when you will all the time have at least 50 GB of storage left)

Yes, total crash. Other datasets too. Thanks for these tips, I’ll give them a shot.

I’m having a similar issue. Video drivers are current (RTX4070, 64gb of RAM) but it seems to overuse the gpu and run it hot until the BSOD. I can typically get through the alignment phase but reconstructing in normal detail results in the failure.

Running 1.2.1 on an old machine with less spec hardware and no issues whatsoever.

Hi, I’ve tried all the suggestions and the problem persists. I’ve also added 2 nvme sticks for dedicated project and cache storage. I’ve updated my bios as well, and adjusted various RAM speed and core settings. Factory reset also did not help. I can render a preview mesh, but otherwise the system totally crashes after alignment.

I’ve run prime95 and my system is stable under these stress tests.

Do you have any recommendations for RAM speed or core settings, or other bios settings?

Thanks
