Couple of questions about SLI and memory

[Moop69]

1. If a motherboard has multiple PCI-E 2.0 slots but it doesn't specifically say in the features list that it supports SLI, can I still run SLI?

2. If a motherboard says in its memory standard: DDR3 2000(O.C.)/1333/1066, will it explode if I try to run it at say, 1600?

1 - Usually, the SLI/xFire situation will be advertised - the single (and looney) exception id that they are 'competeing' liscensures, and I think nVidia has imposed a prohibition that they be mentioned in the same breath! SLI is not 'automatic'; nearly every modern chipset soppurts it, but BIOS and hardware support are the option of the manufacturers...

2 - you can always run memory slower than rated - but figuring out optimal timing parameters may be tricky...
