[SOLVED] Underclocked Rams?

[NATHAN BURMA]

Hi there, Recently I upgraded my rams from 96 Gb (12x8GB PC3L-10600R )to 192 Gb (12X16GB PC3L 14900R) in my Hp Z800 workstation. When I check the ram speed in the task manager, it is showing 800Mhz; before I upgrade, the ram speed showed correctly which is 1333 Mhz. I checked with CPU-Z before and after upgraded, everything is correct. I'm running currently dual x5680 CPUs, I know the speed CPU can handle, which is 800 MHz to 1333 MHz. What I am confusing is, the ram speed should be running at 1333 Mhz as a minimum for 1886 Mhz. Why is the task manager showing the lowest speed (800 Mhz)? I checked in the Bios, it showed 1333 Mhz. I can't change any setting for ram speed in this workstation because there is none. Does anybody have any ideas? Any suggestion would be appreciated.

CPUz doesn't report "effective" data rate. ie, 800MHz on CPUz = 1600Mhz effective (DDR = double data rate)

From what I have read task manager does not always get that ram speed correct.
I would tend to believe cpuz.
Perhaps try a different tool to get another opinion.........hwinfo.
