I have a M2N68-AM PLUS mobo. It has two slots for RAM. The specifications for the mobo state the following:


2 x DIMM, Max. 8 GB, DDR2 1066*/800/667 ECC,Non-ECC,Un-buffered Memory
 Dual Channel memory architecture
 *Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only.
 *Refer to www.asus.com for the memory QVL (Qualified Vendors List)

This is the RAM in there now:

Type      DDR2
Size      4096 MBytes
Channels #      Dual
DRAM Frequency      401.9 MHz
CAS# Latency (CL)      6 clocks
RAS# to CAS# Delay (tRCD)      6 clocks
RAS# Precharge (tRP)      6 clocks
Cycle Time (tRAS)      18 clocks
Bank Cycle Time (tRC)      24 clocks
Command Rate (CR)      2T

And this is the Processor:

AMD Phenom X4 9750
      Cores      4
      Threads      4
      Name      AMD Phenom X4 9750
      Code Name      Agena
      Package      Socket AM2+ (940)
      Technology      65nm
      Specification      AMD Phenom(tm) 9750 Quad-Core Processor

1. Does the 8 GB Maximum refer to the total amount of RAM or to the max per slot?
2. Given the 'disclaimer' in the first quote from the mobo specification page, How do I know which speed of RAM I can purchase [and at what quantity]? Can I purchase 1066?

I, of course, want to put in is much RAM as possible, within budgetary reason.
Thanks,
Jason
