new mobo --> ram clock change

[Wiff]

on our older am3 mobo our DDR3 C. vengeance ram was running at about 650mhz according to Cpu-z. On our newer A88X fm2+ mobo the Ram runs at constant 1333mhz , but why has it changed, i mean higher clock --> better performance, but why?

I didn't change.

I didn't change.

youuuu......you have hacked my RAM

@Wiff

it didn't change at all... 650 MHz is base clock, it's DDR so effective is 2xbase=2x650= 1300 MHz...

RAM is named with DDR# because the frequency is dual-pumped. As the name implies, "Double Data Rate."

667MHz = 1333MHz, 800MHz = 1600MHZ,etc.

1333MHz is standard fail-safe frequency. Even if you get 2400MHz RAM, they will run at 1333MHz unless you adjust the RAM settings in the BIOS.

hmmm

That's normal. My H55 board uses the divider as well rather than effective frequency.
