Fault in non paged area

[Kasc]

About one in every 5 boot ups, i get a Bluescreen with this error (BCCode 50).

I've been told this is usually down to faulty RAM, however this hasn't been happening ever since I bought my PC (it's about 4 months old).

I have overclocked the RAM slightly, however it's rated at 1600Mhz and it's currently over?clocked to 1333, my mobo auto set it to 1028 (or something similar).

Have you got the voltage set correctly?

We need more info to help really, system specs as a bare minimum to start. I got page fault errors with a known good set of ram when I was overclocking the nuts of it (1333 ddr3 trying to run at 17xx at cas8).

XFX Radeon HD 4890 XXX 1GB
Intel Core i7-920 'D0 Stepping' Quad Core Processor

I'm not sure what the voltage should be.

ram should be at 1.65v to run at stock, you'll likely need some more volts on the qpi (vtt on some boards) to get your ram to run at stock speeds and timings. Check that your bios has set the timings correctly for the ram - it's best to do this manually either way.

OCZ forums suggest a qpi of 1.35 for 1600mhz ram at stock speeds - even at 1333 you may need a bit - intel suggest 1.1 - 1.2 iirc and some mobo's use the 1.1 figure.

Have you stress tested / memory tested the system - it could be one duff stick. Try testing with just one stick installed at a time once the volts / timings are set and see what happens. I've had to do this with a new set of ocz reaper which intermittantly failed stress testing even below stock speeds and timings. Testing one stick at at time I found 2 fine and one duff.

The problem is I have no way to recreate the BSOD, I have prime 95, can that stress test ram?

Memtest?

Last time I saw this error message it was because my friend had spilled lemonade on his laptop.
