If using 4GB DIMMs the following setup is recommended as a starting point:


Enter UEFI and navigate to the AI Tweaker section:

2424



Enter the DRAM Timing section:

2425



Set the highlighted DRAM Timings manually to the values shown:

2495



Navigate back the the AI Tweaker screen and scroll down to find the following highlighted voltages and set them manually to the values shown:

2427




Save and exit UEFI, and you're good to go 🙂

DRAM Voltage, use what the DIMMs need.

Other settings use as shown. CPU/NB Voltage depends on CPU, 1.20V is average.

From what I have been experiencing with this mechanical A## H@l3 neither works NOTHING WORKS ! I'm really considering boxing it all up tomorrow sending it back and buying an Intel system that WILL work

Read To Read is the important setting. Changing Write to Write will not hurt but is not usually needed.

Im currently working on 16gb 1600 but there are no guarantees that its stable as I really havent tested it I would like to confirm the above settings before I run any tests.

*edit* I found the answer I think in this thread http://www.asusrog.com/forums/showthread.php?2585-ASUS-Crosshair-V-Formula-BIOS-Guide-Overclocking

Hopefully it will work and I will have no more issues i was running 3 sticks totalling 12 gb at 1600 no problem but definately had stability issues when using 16 but now we will see running prime95 now
