Memory not running at rated speed.

[Kamikazi2142]

So, i first had a difficult time trying to figure out the details on my own, even after the college courses managed to royally confuse me on the simplicity of DDR.

After reading through this nearly 2 year old thread (SEEN HERE) figuring the operating speeds was a simple reverse engineering of calculation used to get the rated speed...

Ok, so now i know something is off.
After a quick (not really quick) 3DMark test, the results post saying my RAM is running at 889Mhz (SEEN HERE)

But my RAM is DDR3-2133 which should be 1066Mhz...

Uh, right...

So how do i manage to configure it to function properly? The BIOS says it is 2133, but windows is only using 889Mhz or the available 1066Mhz...

I am fairly certain it is a windows related issue.

Please download and install CPU-Z CPUID - System & hardware benchmark, monitoring, reporting and then run it. Please post a screenshot of the CPU, Memory and the SPD tab. The SPD tab is for each Dimm slot. Just post shots of the slots with ram in them. This will tell you how to post screenshots.

Make sure your bios is set to use the XMP profile for the sticks if you haven't. Await pictures like Essenbe said.

you'll have to set them manually or xmp in Bios with their rated factory Memory Speeds, Timings and Voltage.
