Why doesn't this cofig file work? (Sandbox .wsb)

Question

Trying to use sandbox, want to use more RAM, this is the config file:

<Configuration>
<VGpu>Enable</VGpu>
<Networking>Disable</Networking>
<MemoryInMB>8192MB</MemoryInMB>
<MappedFolders>
<MappedFolder>
<HostFolder>C:\Users\Public\Downloads</HostFolder>
<SandboxFolder>C:\Users\WDAGUtilityAccount\Downloads</SandboxFolder>
<ReadOnly>true</ReadOnly>
</MappedFolder>
</MappedFolders>
<LogonCommand>
<Command>explorer.exe C:\users\WDAGUtilityAccount\Downloads</Command>
</LogonCommand>
</Configuration>

Still only giving me 4gb when I run the sandbox.
Anyone kind enough to tell me what I'm doing wrong here? Every google search just sends me to the doc for sandbox (where I copied that example from in the first place).
Running win 11 pro so, everything should be functional.
Thanks.

Never mind. I just realized it... d'oh!

(For anyone who's curious, I wrote 8192MB as the value. Just supposed to be numbers - so JUST 8192.
That'll teach me to copypaste everything.
