I plan on building a budget system based around a Phenom II X3 720 BE and an Asus M4A785TD-M Evo AMD 785G (Socket AM3) mobo.

I don't have any experience with Phenom systems (my main rig is an i7), and I initially thought that 1600 RAM was a good price/performance option, and was looking at the G.Skill Ripjaw 4GB for £68.

I noted that the mobo does 1800 as an OC, but I don't know how it achieves it... system OC or higher memory multi? I then noticed the following on TWO for only £7 more:

Geil Ultra Series 4GB (2x2GB) PC3-17000 2133MHz Dual Channel Kit (GU34GB2133C9DC)

Then... I read the CPU description and it says "Integrated Dual-Channel Memory Controller with up to DDR3-1333 support".

Now I am confused about what to get. Am I totally wasting cash getting the Geil memory? As it is a budget system, should I just get cheap 1333 memory?

Help!!!

You wont see virtually any performance boost going over 1333mhz on AM3 especially in gaming.

OCZ Platinum 4GB (2x2GB) DDR3 PC3-10666C7 1333MHz Dual Channel (OCZ3P13334GK) - £65.99 inc VAT

Thats the ram I use in my AM3 rig & the tests I've done - see below.

Graphics Card: GTX 295

CPU: AMD Phenom II X4 955 Black Edition @ 3.6GHz (3.8Ghz = add extra 2 fps)

Ram: OCZ Blade Series 6GB (3x2GB) DDR3 PC3-16000 Triple Channel (Tested at various timings using 2x2GB) / OCZ Platinum 4GB (2x2GB) DDR3 PC3-10666C7 1333MHz Dual Channel (SAME RESULTS)

Crysis 1600mhz 7-7-7-24 = 54.98 fps

Crysis 1333mhz 7-7-7-24 = 54.43 fps

Crysis 1333mhz 6-6-6-24 = 54.87 fps

Crysis 1333mhz 9-9-9-24 = 52.98 fps
