Hello. I also have a Caska device. Mine has 256MB of RAM and ROM. And I use 9.6.13.267029. The primo has slowness in its nature I think. But I don't have any out of memory error so far. As Boki said, check your iGO folder throughly. Get rid of DEM files, decrease ux usage, limit voice, lang map and licence files. Get an emulator and test your iGO in emulator first, if it Works in emulator it will probably work in the unit too. For example my iGO uses ~70MB in emulator with a total of 275MB of map&poi data.
