Is  
`2,340 hours per month` of shared cpu 1x time same in following cases?

1. Run 3 [shared-cpu-1x](https://fly.io/docs/about/pricing/#compute) VMs with 256MB RAM full time.

2. one 512MB RAM and one 256MB RAM full time?

if yes, does it mean that I can run one instance of 512MB RAM and one instance of 256MB ram under free tier?
