RAM not reading the correct speed

[_Jay_]

I have 2 sticks of 1600Mhz RAM installed in my system. CPUID shows the freq at 433Mhz. Shouldn't it be at 800MHz?

Your FSB/DRAM ratio needs to be changed. Setting it to "auto" should solve this.

Update Cpu-z.

Switched it to Auto and now reads this. Still less than 1600MHz.

Update Cpu-z.

I tried that and reads the same as above

Can you manually set the ratio? If so, how many ratio options do you have?

These are my options in the ASUS Sabertooth BIOS: (I had it set to Auto so not sure why it shows DDR3-1151MHz)

Go ahead and set it to 1439 MHz, and see what CPUz says after that.

I switched it to 1728 and got this:

It's because your bus is set to 216 instead of 200. The 1728 figure is correct. You overclock the bus, you overclock your ram. It's that simple.

Thanks for the info. Is it safe to leave it there? Or should I clock it back to 200?

I'm not really savvy when it comes to OC'ing so I don't know what's safe and what's not.

I would set it back to the default of 200 and set your cpu multiplier or "ratio" to get back to your target cpu speed. 200 bus speed x 20 multiplier would give you a nice even 4 GHz.
