Try and experiement with different maxmem settings too 512, 600,640, 670... also play with the waza file size in spi tweaker. 1024k and 512k are my favs. And remember higher available memory doesnt necessarily mean better waza, but it can indicate that (verify with final scores). Sometimes the "CDT" or "IV" options have helped my times so try those too. Most of pi tweaking is system subjective so you will have to experiment with values, until you find what your OS/bios/etc likes. Just my $.02
