DDR3 1600mhz only running at 800mhz in CPU-Z

Hello,

The RAM I own (OCZ Gold) is advertised to run at 1600mhz w/ 8-8-8-24 timings. I have set the RAM to 1600mhz in BIOS, but when I look the DRAM Frequency in CPU-Z it shows it only running at 800mhz.

CPU-Z settings under Memory.

DRAM Frequency - 800mhz
FSB:DRAM - 2:8

It has my timings correct at 8-8-8-24 so I won't post those.

Row refresh cycle time (tRFC) - 88 clocks
Command Rate - 1T

I'm a little sketchy on the settings other than DRAM Frequency, and to me it looks like the RAM that I set in BIOS to run at 1600mhz is only running at 800mhz. What is going on here?

Thanks

-J

    Don't worry... :) Your RAM is running at 1600Mhz.

    1) You set the timings in the BIOS, so no matter what a Windows program reads it, it is running at the BIOS speed.
    2) In CPU-Z, you have to times your RAM frequency by two to get the actual speed. It is taking into account the multiplier, so it only shows it as half.

  3. If I plug my 1600mhz ram into the 1666+ slots can I over clock it to 1666mhz?
