Rough math: each LDPlayer instance with TikTok loaded sits at ~1.5-2GB after the system idles, more under active use. So 30 instances = 48-60GB just for the emulators, plus you want 16-32GB headroom for the host OS + proxies + automation runner. Realistically you're looking at a 96GB workstation minimum, 128GB to be comfortable. Below 64GB you'll be swapping constantly and TikTok's gestures will lag, which itself becomes a fingerprint signal. CPU matters too — modern threadripper or Xeon, the cheap consumer chips choke on 30+ Android instances regardless of RAM.
