What would be the BIOS settings for me to recognize the 8GB of DDR3 ram in 2000, and recognizing that the DDR3 1333(BCLK Frequency (MHz):133), and when I can I work on windows tells me DDR3 2000 8GB RAM (usable 3.99Gb), bios is updated to the latest versions on the website of the manufacturer.

thanks

You need to increase CPU VTT Voltage. If it is not enough, it will drop the memory controller and make it 4GB only.

increased until voltage??

thanks

That is something you need to test, trial and error. It is different for each CPU, even of same model, so I can not help much with that.

Get to recognize the 8GB of ram to DDR3 2000 with the following changes to the BIOS setup:
CPU CLOCK RATIO: X20
VTT voltage: 1.354

CPU temperature in idle modules will retain 39 ? c, full load at 55-60 ? c

will be good this configuration?

thanks
