Hello, I just ran 3Dmark 11 on my computer out of interest, and to my shock found that the memory was only running at 667mhz. Any idea's why or how I fix it please? Can I change it manually in my bios? Because my ram is supposed to run at 1600mhz
The 'Memory' tab is what you need to look at, and if it says DRAM Frequency = 800 MHz then you're running DDR3 1600. Next, the RAM MUST be installed in pairs and it MUST be installed in the SAME color DIMM slots to run as Dual Channel; Blue/Blue OR White/White.
No, if you want Dual Channel use same color; see page 16 of your manual. I always double-check before I post. it's always the same color but sometimes you can use Blue only or White only - in your case it's either but NOT Blue/White Blue/White is killing your Dual Channel.
