Ddr3 1866?

[aalansari]

I just purchased a (8gbx4) set of DDR3 1866 (PC3 14900). My motherboard is a sabertooth z77 with an intel core i7 3770k cpu. The motherboard is rated for the 1866 but the cpu isn't. I read that you would need to set some xmp settings in the bios, but the performance gain between 1600 and 1866 in many cases is around 1%. So I'm a little confused on what might be my best approach here?

- Should I just install the ram and leave everything run on default settings?
- Would it default to the max rating of the CPU (1600)?
- Would it be best if I manually entered the parameters into the bios to run at 1600 or the actual ram ratings?

I'm not planning on overclocking the cpu or tweaking anything, mainly because I have no clue how to do that..but I just like having the performance capabilities when I need it..

My system:
- Cooler Master HAF 912 Case
- Asus Sabertooth Z77 Mobo
- Intel Core i7-3770K CPU
- G.Skill Ripjaws Z Series 32GB (4x8) Ram
- 200mm Fan
- WD 1TB 7200rpm HDD
- OCZ Vertex 4 128GB SSD
- EVGA Geforce GTX 660ti Graphics Card
- Thermaltake 600W TR2 PSU

The CPU can do with 1866 just fine lol i7 3770k of course it will support 2600Mhz memory too. gl

You will be fine purchasing 1866 memory even it its not supported by your cpu.

The performance gain isn't alot if any beside higher benchmark scores, if the price difference is big you are better off getting 1600 memory.

If the memory has xmp profiles it should have one for 1600mhz memory even if its rated for 1866.
