not understand how setting up ram speed

[clau]

I have a new PC, and this is my first time having to set the ram speed to 1866. I've been reading that the Gskill sniper gets automatically set to 1333.
Already updated to bios (99FXAUD3.F9)
Could someone watch me through the settings?

Specs:

Motherboard: GIGABYTE GA-990FXA-UD3 AM3+ (Rev 1.1)
CPU: FX 8120
Ram: two modules (total 32GB): GSKILL F3-1866CL9D-16GSR

Thanks!

Download CPU-Z  from link below.

http://www.cpuid.com/softwares/cpu-z.html

Install it and start it up go to spd tab first and see what you can go to, Then go to memory tab and write it down so when you go into bios you can tell what to change like CAS# Latency (CL)   value what it is here.

Now restart and hit delete and go into bios to memory and set it to manual then find each of those settings and change to what you wrote down from the SPD tab 1866. Make sure eash is set right and voltage is what it calls for since you didnt leave link for ram i cant tell you what voltages to use or timings thats why you have to download cpuz.
Now hit f-10 to save and exit bios and see if it starts if it does well and good if it doesnt go back into bios and change timings from say 9-9-9-9-25 to one number up on each and make sure you set ram 2T which is 2 timings and set it to unganged has gretter tolerance that way report back nay problems and someone or me will try to help.
