Improve result quality

[RazoR2k2]

How can I improve the result quality?

PC Spec: i5 11600K 16GB 3200MHz DDR4 RTX 3060Ti 64GB page file

Train SAEHD settings: Batch size 6 resolution: 128 Iter: min. 150k

Tried batch size 7 or 8 but i got errror Tried batch size 5 and 256 res, error Batch size 4 and 256 can run, but takes too long ~15-18 hour Batch size 6 and 128 res is ~6 hours but the result is meh....

The source is 4k, the destination is 1080p or 4k Faceset extract resolution is 928

If i change the RAM to 32GB and the VGA to RTX 3080 can I train at batch size 8 and higher resolution? Or just let iter numbers over 150k?

Thank you!
