BSOD After Setting RAM Timings

Hello.

A few days ago I started a thread here, asking about RAM timings etc.
I found out that my RAM, which should be running at 4-4-4 15 and 2.1v, was being forced to run at 6-6-6 18 and 1.8v by the BIOS (If set to Auto).
I figured out how to change it, but now I have been getting BSODs whilst playing games. It has happened in Team Fortress 2 and Anarchy Online (although I only installed AO last night so I don't know if it is connected). I have not tried any other games.

I cannot say exactly what the BSOD says, as it happens so quickly I cannot see it all. The only thing I managed to see was right at the bottom, it said something like "Writing RAM to disk", and a percentage count.
When it got to 100%, my computer shut off. I have since returned the settings to Auto in the BIOS, and I have not seen the problem since.

I am running Vista Ultimate 64, and I upgraded my BIOS to the latest version. The rest of the specs are in my signature.

Is the RAM really causing this, and what can be done so I can run it at the recommended settings without getting BSODs?
 
Up your northbridge voltage (possibly labelled NB or MCH) by 0.1v and see how it fairs.
 
These are the settings I have in the JumperFree Configuration page of my BIOS. I am hoping someone can spot a problem or something I should change.
Also, the Northbridge Voltage (labelled, as you said, NB), only goes up in increments of 0.15v.
Words/Numbers in <>'s are what they are currently set at


Ai Overclock Tuner <Manual>
CPU Ratio Settings <Auto>
FSB Strap To NorthBridge <Auto>
FSB Frequency <266>
PCIE Frequency <Auto>
DRAM Voltage <DDR2-800Mhz>
DRAM Command Rate <1N>
DRAM Timing Control <Manual>
CAS# Latency <4 DRAM Clocks>
RAS# to CAS# Delay <4 DRAM Clocks>
RAS# PRE Time <4 DRAM Clocks>
RAS# ACT Time <15 DRAM Clocks>
RAS# to RAS# Delay <Auto - 3>
REF Cycle Time <Auto - 46>
WRITE Recovery Time <Auto - 6>
WRITE to READ Delay <Auto - 3>
READ to PRE Time <Auto - 3>
DRAM Static Read Control <Auto>
Transaction Booster <Auto>
CPU Voltage <Auto>
CPU PLL Voltage <Auto>
FSB Termination Voltage <Auto>
DRAM Voltage <2.1v>
NB Voltage <Auto>
Clock Over-Charging Voltage <Auto>
Load-Line Calibration <Auto>
CPU GPL Voltage Reference <Auto>
NB GTL Voltage Reference <Auto>
CPU Spread Spectrum <Auto>
PCIE Spread Spectrum <Auto>
 
Oh, I also should mention that because the NB Voltage set to 'Auto', I don't know what the actual number it is set at, so I don't know what a small increment would be :(
 
Try changing 'DRAM Command Rate <1N>' to <2N>.

And the nb voltage will be on the lowest setting as your CPU is still at stock speeds. So bump it up by 0.1v from whatever the lowest setting is.
 
Okay, the minimum setting was 1.25v, but because it only lets me increase by 0.15v at a time, I have had to go to 1.40v
I have also set the DRAM Command Rate to 2N

Let's see how that fares!

I'll try and remember to come back and let you know what happens, but incase I forget, thanks :)
