I've googled quite a bit on these three questions but have yet to find definitive answers. Most discussions regarding these two topics brach off or relate only to specific hardware components.

RAM Voltages

1)If a MB is listed as 1.8v, and the RAM in question is 2.1v, will the RAM work on the system, considering the RAM meets all other qualifications?
2)Same question, but with the voltages reversed.
3)What dangers, both physical (frying of components, etc) and theoretical (slower system, memory errors/crash) are likely to result in these two scenarios?

MB Power Connectors

1)MB uses a 20pin power connection. PSU has a 24pin connector (not a 20+4 that are hooked together but are easily separated). Can the 24pin connector be plugged in with 4 pins overhanging, and still power the board?
2)Same question, but the pin counts are reversed (MB-24pin, PSU-20pin...can I leave 4 unused?)
3)If the answers to these are yes in either case, how do I determine which 4 to leave open/overhang?
4)What dangers, in the same vein as mentioned above, are likely to result from these two scenarios?

SATA Cables

1)Do SATA1.5Gb/s and SATA3.0Gb/s hard drives use the same cables to connect to the MB? I have read conflicting answers to this.
2)If the answer is yes, why are there two different types of cables available for sale (SATA and SATAII)?

Thanks in advance.
