 ### What options to use for low VRAM videocardsd?
 - If you have 4GB VRAM and want to make 512x512 (or maybe up to 640x640) images, use `--medvram`.
-- If you have 4GB VRAM and want to make 512x512 images, but you get an out of memory error with `--medvram`, use `--lowvram --always-batch-cond-uncond` instead.
+- If you have 4GB VRAM and want to make 512x512 images, but you get an out of memory error with `--medvram`, use `--opt-split-attention` instead.
+- If you have 4GB VRAM and want to make 512x512 images, and you still get an out of memory error, use `--lowvram --always-batch-cond-uncond` instead.
 - If you have 4GB VRAM and want to make images larger than you can with `--medvram`, use `--lowvram`.
 - If you have more VRAM and want to make larger images than you can usually make, use `--medvram`. You can use `--lowvram`
 also but the effect will likely be barely noticeable.
