Memory config 48 gb kingston ddr3

Memory speed divider: Is this current memory frequency? this is set to 1333.
At the moment the MCH is set to auto.
In the CPUconfig the bclk is greyed out, not sure how to change this.
The and IOH are both set to auto.
At the moment I’m just trying to get the ram install properly. It at leased see all the memory but blue scenes or freezes.
I will look into overclocking once I'm sure the system is stable without and OC..
Cheers for the help

In order to get the 1600 speed you have to keep the memory speed divider at 1333 and raise the bclk from its default of 133 to 1600. The default speed is usually 1333 when the bclk is at 133 unless you change it. The 1600 MCH contains the settings for when you do have the memory at 1600. You can also input those settings manually. On the newer Sandy Bridge based boards, a 1600, 1866, 2133 multipliers are included so you can keep the bclk at standard but just overclock the memory. This board does not offer that feature. So in order to get the memory to 1600, you will need to raise the bclk. As you probably know, that will also overclock the processors as well.

What are the settings that you have in the bios as far as voltages for the cpu's, cpu VTT's, IOH?

I have installed 48 gb of 2x DDR 3 kingston 24GB (6 x 4GB) HyperX 1600MHz DDR3 Non-ECC CL9 DIMM.
Each 24 gb batch are installed in the appropriate slots [red] then [ black] for the other 24gb batch.
My question is in the bios.
There isn’t a choice for 1600 just 800, 1066, 1333. there is a 1600 choice in the MCH strap.
Not sure which to set for this ram set up.
The timings are 9-9-9-27 N1.
I can see how to set the timings 9-9-9-27 but not sure where to set the N1
The voltage is set to 1.65v.
The problem I’m having is the machine keeps blue screening or freezing or crashing out straight to reboot.
I’m trying to sort this out but can’t be sure about the bios ram setup and there doesn't seam to be any clear information on how to setup the bios on the sr2.
The machine is dual xeon x5650 48 gb ram Kingston chosen from the list of compatible memory. graphics is the evga sc 4gb 670 bios is the latest A56 version.
any help would be greatly appreciated.
cheers.
