Asus P5QC Motherboard - DDR3 Compability Problem

I recently bought Crucial CT2K51264BD160B.C16FKD (8 GB = 2 x 4 GB, DDR3L, PC3-12800, 1600 MHz, UDIMM, 1,35 V, CL=11, Unbuffered, Non-ECC) in order to upgrade my system from DDR2 (2 GB = 2 x 1GB, 800 MHz, PC2-6400). I used Crucial System Scanner and it says that my product is compatible with my system. When i use them, my system seems to be starting but i get black screen. 

 

This is what i ve done until now, but i get the same result as i described above:

1. i tried using memories each one alone at the orange slots

2. latest bios update (version 2103)

3. CLRTC clean both by jumper and battery methods before using new Rams

 

Could you suggest me any solution ?

 

Thanks

Did you remove the DDR2 RAM?  You cannot use both DDR2 & 3.

 

Check BIOS settings and make sure CPU & memory options are set to "Auto".

 

In the BIOS select the Reset  or Load Default settings (or optimal defaults) & save & reboot.

 

Is your CPU compatible with DDR3 memory?

Thanks for confirming.  I think you've done everything you can do, so I would suggest contacting Crucial Support directly.   Tell them everything you've done (basically what you described in your posts here) so they can investigate the matter and determine why it isn't working for you.

 

If we overlooked something, please post an update here so it may help others.

 

Good luck.
