Hello, I am building a new computer and I am wondering what type of RAM I should use.

Motherboard: Asus M5A78L-M LX PLUS Socket AM3+ AMD 760G/SB710 Chipset Dual Channel DDR3 1866(O.C.)/1600(O.C.)/1333/1066 MHz 1x PCI Express 2.0 x16 Slots 8-Channel HD Audio GLAN 6x SATA 3Gb/s 10x USB 2.0 Micro ATX

Cpu: AMD Bulldozer X4 FX-4100 (95W) Quad-Core Socket AM3+, 3.6GHz, 8Mb Cache, 32nm (FD4100WMGUSBX)

Thats my Cpu and Motherboard and I'm looking for suggestion for RAM. Please try to keep the price under $50.
 
The motherboard states that the ram that is 1333 and 1066 is supported naturaly at those speeds and that the ram at higher speeds is supported if it is overclocked to those speeds so if you purchased a set of ram that was 1866mhz then the motherboard would default it to a 1333mhz speed and you would have to go into the bios and manually set the speed to the 1866mhz.

Here are a few choices for you to look through and choose from.
 
The motherboard that you have says 1866 (OC) / 1600(OC) /1333/1066 , so it will support the 1600 and 1866 but when you put the ram in it will default to 1333 and you will have to go into the bios and change it to the speed that you want. When the other person posted that the Bulldozer supported the 1866 natively , it will but the motherboard has to as well or you will have to change it from the defaulted speed to the listed speed of the ram.

Im fairly new computers, so just wondering if I use a ddr3 1333GHz RAM will I be able to use the 3 parts together without changing anything (I dont plan on overclocking).
 
If you mean the cpu and motherboard that you listed along with the 1333mhz ram then yes you could. Don't be confused by what I have said it's just the way that they build these motherboards and the more you want to pay the better the features on the motherboard.
If you wqanted to get the 1600mhz or 1866mhz it is a fairly easy thing to set the correct rated speed it the bios , it's just a matter of selecting the speed that you want and saving and exiting the bios. There's not a lot to do but if you did buy the 1600 or1866 the motherboard would put the speed of the ram at 1333mhz untill you changed it.

Thanks for your help :wahoo: I think I am going to just stay at 1333Mhz, because I dont have the money to get a better motherboard. I am going to use the G.SKILL Ripjaws X Series DDR3 1333MHz (PC3-10666) 8GB (2x4GB) Dual Channel Kit (F3-10666CL9D-8GBXL)
