Memory Manager
DMA read/write problems once an app is running. For the launcher itself and the startup handshake, see Client · Common Issues.
"Initialize Memory Manager Failed"
Shows "cannot connect to DMA device". This is not a software issue — run a speed test yourself to check the connection.
In Apex specifically: DMA can drop a few minutes in because the game itself blocks the firmware. Also not a software issue — you'll need to find your own workaround.
Swapped the DMA DLLs yourself? Check this first
DLLs in the wrong folder produce this same message — it is not always the connection. leechcore.dll and friends belong in the install folder only; a copy in an app folder stops the app from starting. See DMA Convert.
Stuck on "Initializing memory manager..."
Also not a software issue. Try in order:
- Client → Settings → Cleanup → clear the host's physical address cache, then retry
- Still stuck? Disable MemMap directly from the app's menu
