Problem setting RAM timings..

[Warmo161]

Hi, for xmas I bought Corsair XMS3 ram as part as my first pc build, but I am having problems setting the timings up...

Since then, I have been running at 1333 and when I set 1600 in the bios, Windows gives me a BSOD and I have to restart my pc.
When My pc comes back on I get a overclocking failure message from my bios

I then read the manual and decided to set the timings too.
I did this by setting the Ai tuner to manual and then setting them

After this it still doesnt work and I get the same problems.

My pc specs are below:

AMD 1055t processor
Crosshair iii motherboard
Corsair xms3 4gb ram (2x2gb)
6870 graphics

My friend got his ram sorted and he's running nearly the same specs as me
(nearly as he has a different CD drive, PSU, case and HDD)
He also has the ram in different slots than mine (I know it sounds strange, but could that be a factor?)

I haven't touched the voltage, I left it on auto both times

So, could it be a problem with windows or the motherboard/ram?

Ok, so should I try setting the voltage as well?

I'm not sure about overclocking the fsb as i'm running on the stock cpu cooler and would it overclock my cpu?

So, even if I do get it working at 1600, will there be much of a performance boost?
As I have no problems with it

And when I get round to buying a better cpu cooler, will this affect me trying to overclock?
