Need help overclocking NB frequency Sabertooth 990fx

post #1 of 2
Thread Starter 
I finally had time to start overclocking on the Sabertooth board in my sig rig. When this chip was in my old board (Asus M4A89gtd pro/usb3) I was able to overclock the NB to a stable 3000MHz. With the Sabertoooth board any change in the NB, even a small overclock of 200MHz, results in a hard reset and no post.

The CPU overclocks better than it did on my old board, but any change in the CPU/NB frequency = fail. With the CPU stock, and the RAM down-clocked to 1333, I raised the CPU and CPU/NB volts incrementally up to 1.45 on the CPU, and 1.35 on the CPU/NB. The result was always the same hard reset to no post. I also raised my DRAM voltage to 1.67 with no change.

Here is a screen shot of my configuration on the M4A89GTD pro/usb3.

I may be missing something obvious in the UEFI Bios, but frankly I am completely out of ideas.

Ever have any luck resolving the issue. I swapped from 32 bit to 64 and am having the same problem. I used to run the cpu/nb at 2600. It wont even post at 2200 :s
