Noob question about ram types



Not true.

The speeds supported: 4 x DIMM, Max. 16 GB, DDR3 2000(O.C.)/1600/1333/1066 ECC,Non-ECC,Un-buffered Memory

Use either Certified {See Memory Support List/Specifications -tab}- http://usa.asus.com/product.aspx?P_ID=nlWYrI9wlNIYHAaa

Tested {Example} - http://www.ec.kingston.com/ecom/configurator_new/modelsinfo.asp?SysID=63484&mfr=ASUS/ASmobile&model=M4A87TD+Motherboard&search_type=&root=us&LinkBack=http://www.kingston.com&Sys=63484-ASUS/ASmobile-M4A87TD+Motherboard&distributor=0&submit1=Search

Good Luck!
 
"Solved" = No! While I appreciate the {Moderator} status and the OP notion to choose to believe @Maziar - this is really bad advice. I stated Certified {ASUS calls QVL} & Tested - either if a good choice.

^ Then I "wish" I'd quit seeing all of the Memory that "should've/could've" work with problems being posted here - it's driving me nuts. Even different "lot/bin" don't play together well.

Example {same model #/different bin/scroll to "JEEEZZ!!"} - http://www.tomshardware.com/forum/page-280059_30_50.html

I Strongly recommend Certified <or> Tested.
