try to disable in rendering the first GPU connected to monitor, and use it only for AI Denoiser, in order to render with only 3x GPUs.
If it works, the issue is in the powering/PSU.
What is the frame resolution?

Right now ive got 2900 watts of power. for 4 rtx2080ti. And it still crashes. Even with 1 card assigned for denoiser. So guys if anybody faces the same issue - DO NOT buy additional ram (as i was recommended firstly) and DO NOT buy additional PSU. Those are not the cause of the issue. Not the frequencies, not the temperatures. I dunno what is the cause really.
p.s. It is also not the octane version that matters. Just tried 4.04 instead of 2018.1.3 - crashes in the same way.
