Help to make 1333MHz DDR3 run at 1333MHz

post #1 of 12
Thread Starter 
Hi, I need help to make my rams work in DDR3-1333 mode
Look at my system for details on specs

My CPU is overclocked to 400FSB x7
Here are the bios settings:

FSB Strap to Northbridge: 333(may need changing)
FSB: 400
DRAM Frequency: DDR3-1280
Data Command Rate: 2N
DRAM Timing: 6-5-5-20
DRAM Voltage: 1.86
CPU Voltage: AUTO

Can someone help me to get the RAM to work at 1333MHz(667MHz) while having the CPU overclocked to 2.80GHz or 3.00GHz?
Also keeping it stable

Thanks

When i go to choose DRAM Frequency, there are only optins for DDR3-1280 and DDR3-1600
How can i get DDR3-1333
Help please

you need to change your fsb so that (fsb x the ram divider) = 1333

hope this helps!

Thanks
Im a bit of a noob - what is ram divider?
Can you calculate what my FSB will have to be
post #5 of 12
its the number that you fsb is multiplied by to get the ram speed.
im not that familiar with intel but around 406 fsb should do it just raise the fsb till you can select 1333. it will increase the cpu speed a bit but not much (406*7=2842)

EDIT: you might need to go up to 416 so make sure that your cpu is stable
