ASUS motherboard M4A785TD-V EVO
AMD Phenom II X2 555 Black Edition Callisto 3.2GHz Socket AM3 80W Dual-Core Desktop Processor - C3 Revision HDZ555WFGMBOX
G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model F3-12800CL9D-4GBNQ

I want to add 8 GB of memory to my computer. I checked with Crucial and they say the following memory is compatible with my motherboard:
Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model BLS2KIT4G3D1609DS1S00

When I put the Crucial memory in, the computer won't boot. I took out my GSkill memory, replaced it with the Crucial memory and it still won't boot. A friend told me to take out the Crucial memory, put the GSkill back in, boot up the computer and go into the BIOS and change the settings and save, then put the Crucial memory back in.

But what am I changing and what am I changing it to? And why? (Yes, I'm one of those people who always wants to know why.)

I have the memory in the correct slots so I'm not sure why I have a dead computer when I use memory that Crucial says is compatible with my board. And yes, I know I sound like a total noob. Usually my hubs builds my computers and deals with the hardware. I'm more of a software person. But he's not here to fix this and I need to get this upgraded.

Any help you can give is appreciated!
 
Solution
Install the new DRAM, go into BIOS, enable XMP, select profile 1 and give it a try..if no joy, make sure you have the latest BIOS and try again

Honestly I've not seen many good reviews of that ballastix sport memory, and its very possible the timings on the cruical memory are worse than the gskill, making it not be able to run. Check the timings on the gskill (perhaps somethhing like 9-9-9-24) and look for similar numbers on the crucial. If they are higher on the crucial, you'll have to change them in the bios to make the kit work. also check for Dram Voltage on the sticks to see if it needs to be higher.
