Hi,
Thanks for posting in Microsoft MECM Q&A forum.
Per my experience, the client setting should override anything configured at installation time. So the cache size client settings will win and the Maximum cache size will be 30% of the free disk.
Hope it helps. Thanks for your time.
Best regards,
Simon
