What setting to get RAM to run at 1600?

[mgh]

I will be building my PC tomorrow. I have a MSI 870-G45, with 2X2 G.SKILL ripjaw RAM. I understand it will default to 1333, and that I need to change a BIOS setting to get it to run at 1600.

So do I go to DRAM voltage, take it off of auto, and type in 1600?

Thanks for any advice

More than likely the default is 1066 MHz.

Q - What exact G.SKILL's do you have? Please provide a link.
Q - What AMD CPU do you have? Some are limited to 1333 MHz

The manual that came with the mobo lists Northbirdge chipset RX780, and Southbridge chipset SB710. The link states NB is 770.

Thanks for the responses.

Any suggestions how I can do this?

I'm not familiar with your BIOS, but is appears that you need to adjust the FSB/DRAM Ratio, and may need to adjust the timings if the RAM isn't recognized as XMP in CPUz. The Adjusted DRAM Frequency should show 1600 MHz after adjustment. You may need to increase the CPU-NB Voltage by ~+0.1V.

Otherwise you might want to 'try' OC Genie Lite -> Enable. http://www.overclockers.com/msi-890gxmg65-review/

CPUz - {Remember 800 MHz X 2 = 1600 MHz in the SPD Tab} http://www.cpuid.com/softwares/cpu-z.html

Thanks!

I adjusted the ratio to 1:4, and cpu-z shows frequency at 1600.

I have another weird thing happening when I turn on OC Genie Lite. I thought I would post my experience in the overclocking forum, see what people have to say there.

When I enable OC genie lite, my mouse pointer hesitates, though not all the time.

Thanks for the help.

If your BIOS has 'Legacy USB Support -> {Enabled}' try to change it to {Disabled}, save and exit.
