Windows 7 - Stuck at 1066 Memory Speed

[Toasticuss]

Hey guys, just recently I noticed that I've been running my DDR3 2GB sticks at 1066 when they are capable of running at 1600.

This is the memory - Newegg.com - OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory Model OCZ3G1600LV6GK

The motherboard is a ASUS P6T LGA 1366

For the processor, its a stock i7 920 Bloomfield @ 2.66 GHz.

BIOS detects the memory at 1600MHz, so in the BIOS I changed the memory speed from 1066 to 1600, saved and booted into Windows, I ran Speccy, a hardware analyzing tool and its still reporting the speeds I had before. The BIOS said on "Locked" CPUs RAM is locked to 800 & 1066 speeds, is that the problem?

Is there anything I can do to speed things up a little bit? I'm not very familiar with overclocking but I would appreciate anyone's input on this.

Thank you.

Here is the RAM output log if this can help anyone....

The Bios settings 1066 and 1600 are just ratio settings.

From what I see you are running at 1603.6 MHz. DDR or Double Data Rate means your memory speed is Double or 2 x's the DRAM Frequency.

2 x 801.8 MHz = 1603.6 MHz

But Windows lists the rams max bandwidth fairly low...

Max Bandwidth	PC3-8500F (533 MHz)

That is not the Max. Bandwidth, Window is just reading the Memory SPD Table (for lack of the official term). If you want to see the actual memory bandwidth you need to run a benchmark from a program like SiSoftware Sandra or Everest Ultimate.

Alright, thanks.
