I have a Asus U32U Rx012D. Here is the relevant specification :
Memory : DDR3 1333/1066 MHz SDRAM, 2 x SO-DIMM socket for expansion up to 8 GB SDRAM *1
My processor is an E450 which means DDR3 1333 and 1066 support is present. The RAM chip in the laptop is the manufacturer installed chip.
However, when checking the RAM speeds, the speed that I am seeing is 667MHz.
asheesh@ashrj-U32U:~$ sudo lshw -C memory *-memory description: System Memory physical id: 26 slot: System board or motherboard size: 2GiB capacity: 2GiB *-bank:0 description: DIMM DDR3 Synchronous 667 MHz (1.5 ns) product: HMT325S6CFR8C-H9 vendor: Hynix Semiconduc physical id: 0 serial: 32C0EB88 slot: A1_DIMM0 size: 2GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:1 description: DIMM Synchronous [empty] product: Array1_PartNumber1 vendor: A1_Manufacturer1 physical id: 1 serial: A1_SerNum1 slot: A1_DIMM1
Even the motherboard A50M doesnt support clock speeds below 800MHz.
Why this discrepancy in clock speeds?
