memory allocation errors

After intermittently crashing with "memory allocation error", I upgraded my video from 2Gb to 4Gb and the game continues crashing.
My system has 16Gb of RAM and shows at least 4Gb free when I get the error, so I don't think it's RAM.
I've tried running OpenHardwareMonitor and it doesn't show any issues (GPU core Load).
Since the last three 'engine' upgrades, the crashes are getting worse / more frequent.
I've turned all of the settings to lowest and the game still crash.

Proc: i7 860 @ 2.80GHz (yes, it's an oldy)
RAM: 16.0 Gb
Window: 10 Pro
Vers: 22H2
Build: 19045.248
Video: Radeon RX550
VRAM: 4 Gb
AMD: Adrenalin 22.11.2

Monitors:
#1 27" Samsung C27F390 1920 x 1080 HDMI
#2 27" ASUS VP279 1920 x 1080 HDMI
#3 24" LG 24M47VQ 1920 x 1080 HDMI
#4 24" LG 24M47VQ 1920 x 1080 HDMI

Display config: 4 3
1 2

Running 7 virtual desktops. SpeedFan running on Screen #3 on desktop 1, Thunderbird email running in screen #2 on desktop 2.

This continues to happen over about the last 6 AMD drivers, but has only blue screened with the latest two drivers.
Really seems to have a problem with Rainmeter (screens #3 & #4), sometimes crashes Rainmeter minutes before the game crashes.
Has also crashed LibreOffice Calc (screen #2) and/or Quickstarter.
Latest blue screen with Thunderbird off, Calc off, Rainmeter off.

Besides getting a newer computer, any suggestions?

You have the modern drivers for AMD, which is really good. Unfortunately, this may be the source of your problems with Zero-K.

Back at the release of 22.11.1 drivers, I and other players with AMD cards(some not all?) had very bad hiccups/lag, with bad water rendering effects and other kinds of technical issues. I'm currently on 22.5.1 drivers, and I don't have problems. I have not tested 22.11.2 drivers, so I could be barking up the wrong tree.

Just updated my drivers and the problem from before does not seem to occur for me.
