Dude zilliqa has 1024mb DAG, it stay on epoch 0 forever ^^ (extra-dag-epoch 0  ) and eth has around 4.258GB and not 5GB DAG. Look in the log.

You mine on windows10? It reserve much vram on nvidia cards. But i am on the way to reduce vram usage on windows10. Maybe i found something in the last days. 1060 6GB had around 700mb free in the past, now after windows10 update and driver 430.86 i have 1400mb free on 11 cards and 1 card has 1600mb free. The cards can hold Zil and ETH DAG at the same time.

I'll try another rig with 6GB cards, there are only 600mb free per card

By the way, windows developer mode has no advantages for mining.

May you share the direction you have taken to achieve those amount of free Vram?
I am following the same objective with a rig with 650 MB free/card but I was able to increase it up to 950, that is good but not enough.
I Removed everything not hidden  that may run in background, almost Cleared all the effect of  ShellExperienceHost.exe , but I am short of 150 mb
