Memory Leak with Dolphin 4.0.1/4.0-409 (64bit)

[Shonumi]

That version of Dolphin tends to get random crashes though. Since that version is no longer supported, you'll have to deal with those kind of issues. If I were in your position, at the very least I'd use something after the FIFO-BP merge (which eliminated random crashes for most people) and after the second new-ax-hle merge (3.5-1154) if you need HLE audio (your specs are good enough for LLE audio to run just fine).
