AMD E-450 Memory speed issue

[agnu]

Hi!

I bought a lenovo thinkpad e125, with an AMD E-450 APU. According to the news, and AMD's website, the E-450 has a memory controller that can handle 1333mhz memories, which i have in my netbook. The memory is Samsung made, and the speed is PC3-10700, according to speccy.

The problem is, that in every measurement software (speccy, cpu-z, gpu-z), i see that the memory is operating at 533mhz (which means 1066mhz).

I couldnt find any memory related settings in the bios (updated to the latest one). The latencies are: 7-7-7-20.

Any advice? 🙂

note: i checked gpu-z because the vga card is using the System ram as well
note2: i tried looking at the values when the machine was under heavy load (both cpu&gpu), but the frequency was still the same 1066.

Some laptops intentionally downclock the RAM, either to save a minute amount of power, or to allow for them to use cheaper, slower, RAM sticks in production of that laptop if they need to.

does CPU-z pull the speed that the memory is "currently" running at?

you might try putting a load on the unit (run a benchmark)...and while it is running, initiate CPU-z and see if the numbers are the same

it turns out that i probably have a DDR3L module which is limited to 1033mhz (the mobo suports 1333DDR3 and 1066DDR3L). does anyone know what is this ddr3l?

I see you posted this on tomshardware also http://www.tomshardware.com/forum/307458-30-memory-limited-1066mhz

That said, for my kids computer that is using brazos, with built in APU, I have to overclock the APU to adjust the memory frequency. I don't believe there is a separate memory multiplier. Some have it, some don't.
