G575 AMD E-450 1333mhz ram?

[ryuh90]

OK so here is my question, recently I brought 4gb ram @ 1333 mhz to replace the ram 1066mhz ram(to benefit the E-450 APU) and the system detected it as 1066mhz. I have the latest BIOS(V. 2.02), all updates installed, and nothing to tweak memory frequency in the BIOS.

So my issue is how can I take advantage of the full speed of the 1333 mhz ram?

according to the manual below (page 21/32) g575 doesn't support 1333mhz ram so there's nothing you can do.

memory: 8gb max7 / pc3-8500 1066mhz ddr3, non-parity, two 204-pin so-dimm sockets

I don't quite get why it doesn't though? 

I mean this right here is the same machinehttp://shop.lenovo.com/us/laptops/essential/g-series/g575, and it comes with 1333 mhz ram, or is it a different motherboard and bios than the previous model?

i have no idea but please, give me some time for re-search.

Hello ryuh90

Yigit is right this model is compatible with DDR3 1066MHz memory

This could be some mistake mentioning the memory supports 1333MHz however, Yigit is working on it and will get some detail soon.

Best Regards,

Thank you for all the help  

I appreciate it. Just wish I could get some more power out of the ram for the gpu.

according to this, E450 do support 1333 mhz ram speed.

In theory I believe that the AMD E-350 unofficially supports 1333 mhz ram too. I have even read people saying they got 1600 mhz ram on the E-450, probably with overclocking though.

hold on a sec, do you have the E-350 or E450, the E350 only supports 1066 mhz ram, it doesn't support 1333 mhz ram.

I have the E-450 with radeon hd 6320.
