Sabertooth 990fx oc question

[mojothehut]

Hey all
I'm running an AMD 975BE on a Saberooth 990fx.
I'm using the OC profile with the latest bio. It pushed my cpu from 3.6 to 3.92ghz .Runs nice and stable and all that, not much warmer than default with my Hyper 212.
However, my 16gb of Corsair 1600 is running at 1749mhz. The OC profile refuses to let me run it at default 1600 which is what I'd prefer. The timings are a tad better at 1600 than 1749.
I can't for the life of me figure out how to get my ram back to it's default 1600 9-9-9- timings.
The closest memory speed settings are 1490mhz D:

Any idea how to get my ram back to stock 1600mhz?

Hi, I have the 965BE at 3.96ghz and Corsair 1600 at 1600.
In the BIOS:
The CPU bus frequency had to be set at 240 and Multi at 16.5.
The PCIe is 100.
The CPU/NB is 2400 and the HT is 2400.
I was given this OC by an NVIDIA member.
Try that and see how you go.
