    Hi dpombal 

     

    Even though F8 supports ~3 GB, you’re only getting access to ~1.5 GB during refresh.

    The reason is during refresh, Fabric allocates temporary memory for query folding, compression, dictionary building, etc.

    If other workloads (like Power BI queries or other dataset refreshes) are using memory at the same time, your dataset gets less than the full 3 GB.

     

    Check Real-Time Memory Use in Metrics App

     

    • Total capacity usage at the time of refresh

    • Memory and CPU consumed by other workloads

    • Whether throttling or evictions occurred

     

    • Run the refresh during off-peak hours

    • Avoid overlapping with other refreshes or DirectQuery loads

Hi dpombal, 

 

That 3GB limit is for the entire capacity, so if you have more than just that one report running, your report cannot use the full 3GB. 

 

I recommend either reducing the data size of your report if you have any unnecessary data, or upgrading to a larger capacity.
