8 gig of Memory Need Help

:sweat:  I Just put together a new system and I cant utilize the 8 gig of memory that I installed... I'm hoping there's a workaround for this.

Here's the system.

Intel I7 860 2.8GZ

Asus P7P55D-E Pro Motherbord

G.Skill Ripjaws Series 4x2GB DDR3 1600 (12800CL7D-4GBRH)

ATI Firepro V4800 GPU

Intel X25-M SSD

Yada-Yada-Yada...

In the BIOS only 4 gig is recognized, Under system information in Win7 64bit, 8 gig is listed with only 4 gig listed as usable. The manual for the motherboard states that " acording to Intel spec definition, DDR3 1600 is supported for one dimm per channel only. Asus exclusivley provides two DDR3-1600 DIMM support for each memory channel." it then refers to the Ai Overclock Tuner in the BIOS. I did change settings around in that section but still could'nt get the full 8 gig to register in the BIOS. Honestly I'm not familiar with settings for Over Clocking.
I'm hoping some one here can help me with the settings to get the full 8 gig utilized.

Thank's Jim H.

Go to Msconfig>Boot>Advanced options and make sure "Maximum memory" is unchecked.

Some people resolved the issue by removing the CPU and straightening the bent pins in the socket.

During installation of CPU, some pins may have been bent. Since the memory controller is in the CPU, it may not have full control over memory due to bent pins.

Motherboard sees 8 GB RAM. CPU cannot control 8 GB RAM due to its crippled memory controller. BIOS confuses what to report about RAM, then decides to report 4 GB.

There is a CPU utility called CPU-Z, which can be found @ http://www.cpuid.com/softwares/cpu-z.html , to get info about your system.

Be sure to download the correct version 32-bit or 64-bit for your Windows.

Try clearing the bios by removing the battery for 30 secs.
