Ok so my little brother comes to me yesterday with a motherboard. Im like...wtf? He said he wants to build something new and he got this board for free from a friend. I need some help sorting out memory for it as for I honestly dont know much about matching everything to run the best. Here is what he has:

Asus P5Q

http://www.asus.com/products.aspx?mo...11&l3=709&l4=0

* Intel LGA775 Platform
* Intel® P45 chipset
* ASUS 8-phase Power Design
* Dual-channel DDR2 1200/1066/800/667 MHz
* 100% High-quality Japan-made Conductive Polymer Capacitors! (5000hrs VRM, over 5 years operation lifespan)
* ASUS EPU-6 Engine
* ASUS Express Gate
* ASUS Drive Xpert
* VRD11.1 CPU support (backward support VRD10.X CPU)

We went to newegg.com and found this processor that he wants:

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Quad-Core Processor

http://www.newegg.com/Product/Produc...82E16819115017

and now its down to RAM. I see the motherboard supports DDR2 1200/1066/800/667. now he wants to run photoshop so I was suggesting to get the most ram possible. When we look under ddr2 1200 we only car get 1GB stick. when we look under ddr2 1066 we can get some 2GB stick which may do but when we look under ddr2 800 we can get up to 4gb stick.

I know as the numbers get smaller and smaller they get slower. but what do you think would be best for this setup? 4gb of ddr2 1200 with the processor? or 8gb of ddr2 1066? or 10-16gb of ddr2 800?

also when reviewing the motherboard everyone talks about overclocking the processor and or the memory to match speed ratios...i dont know how to do this or what they are talking about but any information would be great. I dont want to blow this thing up just build a nice setup for my little brother.

THANKS
