Asus P5N-E SLI/Q6600 Problems

Hi I'm kinda new at overclocking, I have gone through your tutorials and I have basic Knowlegde. My problem is when I overclock my system in the bios it crashes about 1-2 mins into the desktop, but when I use nvidia's nTune, its excelently stable.

I used nTune to get an overclock of

Asus P5N-E 650i SLI
Q6600 = 2.7Ghz
Bus Speed = 309.1Mhz
Rated FSB = 1236.1Mhz
DRAM F = 463.7Mhz
FSB : DRAM 2:3
DDR2 3GB = 927Mhz (5-5-5-31)
Vista 32 Ultimate

If I try to repeat this values in the bios, the system posts ok but crashes about 1-2 mins in the desktop. Is there aby reason to this? Also I read ntune has access to the bios and can store the overclock values, but it deosn't for me.

I can't also asign nTune to load the saved overclock profile when windows starts as it fails, I have to manually load it each time which is a bit of a bother to me.

Please if anyone can help me I would be gratefull. I spent the whole of yesterday (13.5 hours) trying to OC my system.

i would say that when you do it in the bios it is changing something else too,

what RAM are you running:
927mhz is relatively quick

My Ram is an A-DATA 800Mhz 3GB (1x3). My stock Ram speed is 801mhz. When in the bios I only change all the above settings according to what i saw on nTune.

I'd have a good read through this thread.

The P5NE-SLI is a bit funny with 4 sticks of RAM, especially when clocked, so you're probably better off leaving it at stock speeds and clocking the CPU first, when you've got that stable start fiddling with the RAM speeds.

thanks so much for your help. I almost gave up on this.
