RAM unstable after overclocked CPU

Hi i'm beginner at overclocking. I've overclocked my Xeon X5450 for 3.48 GHz Voltage 1.2375V with Asus ROG Commando mobo. I've underclocked RAMs 800 MHz to 772 MHz for stability Voltage 1.8V. Then i've tested the CPU stability with using Prime95 for 2 hours. I've done the test without errors. After the test i was working with Dreamweaver for 3 hours i've got that BSOD 'Memory management' and i've got different BSODs. I'm not sure the BSODs are caused by RAM. It could be caused by CPU.
BIOS Settings:
AI Tuning [Manual]
CPU Frequency [386]
DRAM Frequency [DDR2-772MHz]
PCI Express Frequency [100]
PCI Clock Synchronization [Auto]
Spread Spectrum [Disabled]
CPU VCore Voltage [Auto] (it works at 1.2375 V)
FSB Termination Voltage [Auto]
NB VCore [Auto]
Memory Voltahe [1.800V]
DDRII Cannel A REF Voltage [Auto]
DDRII Cannel B REF Voltage [Auto]
DDRII Controller REF Voltage [Auto]
SB VCore(SATA,PCIE) [Auto]
SB Chipset Voltage [Auto]
Asus C.G.I [Disable]
Static Read Control [Disable]
Configure DRAM Timing by SPD [enable]
CPU Configuration:
CPU Ratio Setting [09.0]
C1E Support [Disabled]
Max CPUID Value Limit [Disabled]
Vanderpool Technology [Disabled]
CPU TM Function [Disabled]
Execute Disable Bit [Enable]
SpeedStep [Disable]
There are my bios settings. Is something wrong on bios settings i'll change it.
System Specs:
Intel Xeon X5450 CPU
Asus ROG Commando P965 Chipset Mobo
AMD FirePro V5800 1GB GDDR5 128 Bit GPU

A pretty old rig you have there mate.
You have to ask yourself the question... is trying to OC this one really worth it.

Those older components don't have much head room to be pushed over spec.

That Mobo can handle 4 GHz+. i wanna overclock it. I think it really worth for overclocking.

Hmmm I can foresee problems such as stability.
I just don't think the components can handle it.

I mean a 280w power supply, that is no spring chicken we are talking about.
First thing I'd check is the power draw at the wall under stock load.

Power is enough for rig. I'll get new psu. What's wrong in bios settings? CPU can handle 4 GHz+ my mobo is powerful for oc.

if you cant help you should not post, he didn't ask for advice on is it worth overclocking.
i my self have no input on this but a older tech guy will be along soon to help no doubt.

in the mean time running memtest84 or the windows memory test tool will tell you if there is a memory based problem.

I'll test RAM with memtest64. I'm completely sure that CPU works fine.
