Z400 Workstation DRAM Frequency is 533MHz

[NautTboy]

Z400 Workstation v2 DRAM Frequency shows 533MHz.  Is this normal?  My other DDR3 PC with AMD CPU shows 667MHz.  Checked BIOS with latest update and dont see anywhere I could see for frequency.

ram speed is set by the memory modules, the installed cpu and last by the bios

just because the ram is able to run faster,  than the 533mhz value the cpu (and bios) must also support faster speeds

the z400 supports 800 MHz, 1066 MHz and 1333 MHz DDR3

if you are in dual channel mode then your RAM is being accessed 1066 million times per second with the clock running at 533MHz.  (533x2=1066)

non standard memory configurations (IE- different sized modules or odd number of dimm modules) will result in single channel memory mode 

DDR3-800	PC3-6400	6400 MB/s
DDR3-1066	PC3-8500	8533 MB/s
DDR3-1333	PC3-10600	10667 MB/s

your installed cpu's memory controller may only support the JDEC 533MHz speed

and even if the dimm module(s) and cpu supports the faster 667MHz speeds the bios may not allow overclocking via intel's XMP setting or the AMD equivalent of it
