What is the issue?

Hi,

Is there a way to make Ollama uses more of my dedicated GPU memory? Or, can I tell it to start with the dedicated one and only switch to the shared memory if it needs to?

Server logs might give some insight to why this is happening.

From what I've investigated, this appears to be a general hipMalloc behavior issue when allocating more than 4GB, not specific to Ollama.

This looks like a dup of #7107 - the only workaround for now is to downgrade to a driver OLDER than 24.9.1 until 24.11 comes out which should have the fix.
