Hello folks,

I'm just having all kinds of trouble with my RAM ever since I built my system. According to various programs I sometimes have 3GB of RAM, sometimes I have the full 4GB that I installed. Some say its running at 800mhz, some say that its running at 1600mhz. In the Bios, I changed what I believe to be the RAM to 1600mhz. Can anyone help me get this all straightened out? Please, thanks. :( 

Windows 7 Professional 64-bit
Intel Core i-7 860 @2.8GHz -- 1156
Gskillz 4GB 1600mhz RAM 2 x 2GB

Your DRAM frequency in your BIOS should show 800MHz, which relates to DDR3 1600 (2x800). You can confirm this with CPUID's CPU-Z under the memory tab.

I dont understand. It's supposed to say that?

CPU-Z says DDR3 1096MB. Dual Channels. NB Frequency 2407.5MHz.

Under the Timings section it says:

DRAM Frequency 802.4 MHz.
FSB:D RAM 2:12
CL 9.0 clocks.. etc etc...

You are running at DDR3 1600 by the DRAM Frequency showing 802.4 (FSB:RAM 2:12). It is 800 x 2 given you DDR3 1600. I'm not seeing an issue with your speeds, unless someone else does??

Haha, I don't know. I'm just asking. Is that what its supposed to be? I bought DDR3 1600MHz RAM. Am I using it to its full capability or does my motherboard have it running slower than its designed speed?

From what you're saying, I can almost gather that it's fine.

From what I'm reading, everything looks to be running fine so you should be good to go.
