Editing ursa cine 12K LF file on Good Win workastation. I am experincing glitches in viewer and rendering. Any idea?

I have 64Gb ram ddr4 2400mhz with good cl times
I run Resolve and all software folders in internal NVMe 1Tb 1Gbps Pcie 3.0
I read footage (OCF) from external ssd between 500 and 800Mb/s or somethimes pro HDD at 280Mb/s (Seagate exos)
CPU is ryzen 5900x 12/24 4GHz on X570 chipset.
GPU is RTX3090 24Gb Founders Edition.
Windows 10 latest stable.

similar to my machines, i have 3090's in two of them, i'm also running w10
i don't see glitches in my view port, or anywhere

do you see the glitches on your hero mon, or on exports?
do you see anything in windoze error logs when it happens?
look at GpuZ, are the GPU's overheating at the time, or drawing a ton of power when it happens?
is there a specfic bit of media or process that can trigger this, or is it a random thing, or constant thing?

I'd prolly discount media or access, as either of those resualt in a media offline banner, or software hangs
GPU's esp AMD's in the trashcan mac's would create glitches, as would overheating Nvidia, or unstable power to the machine, or unstable PSU, so that's maybe worth looking into

data point only...
i have two similar machines - 2x xeon 40c-80t / 128g ecc ram / 1200w PSU / behind a big UPS / storage on SAS, that's all a bit diffrent, but around the same envlope of performance, OS and GPU are the same, no issues visiable
