why do you choose the QL1M ? have you bought the X11SPA and no money left ?
I recommend you take a look at the cascade lade ES2(some sellers call this QS, but this is wrong.)
QQ8B = 8C 2.8Ghz base
QQ8A = 14C 2.6Ghz base
QQ8M 16C 2.1Ghz base
QQ8Q = 18C 2.4Ghz base
QQ89 = 24C 2.2Ghz base
more expensive but no compat. issues because they share same microcode than the prod.unit prcessors.
