Mobo specs from lshw:

ASUSTeK COMPUTER INC.
M5A99X EVO R2.0
AMD FX(tm)-8320 Eight-Core Processor

Unsure - will have to examine it pre-purchase.

Yeah, looks like my RAM is rated for 1600MHz but is running at 1333MHz
due to ... BIOS settings? Motherboard limitations?

Motherboard appears to support these RAM DIMMs:

1066MHz - 1866MHz and 2133MHz OverClocked.

(Side note: cannot copy from the PDF - Okular says: "Copy forbidden by
DRM".  That's just weird.)


Looks like I can set the Memory Frequency to 1600MHz under the "Ai 
Tweaker" tab in BIOS.


That helpful tip was followed by pages of mind-numbing (YMMV) info on 
overclocking.

I think I may play with these a bit, at least memory frequency to 
1600MHz initially, before I even buy more RAM.


Thanks!
