PC Switches off - Kernel-Power

**evilsatan** · 11th October 2011

Reset BIOS to optimised defaults again (RAM voltage to auto, CPU advanced features all on again) and swapped out the OCZ gold RAM for my G.Skill Trident RAM and it has been on for 48 hours. I had previously tested the OCZ RAM with memtest for 12 hours with no errors, had swapped the sticks around, tried both dual channel sets of banks and tried the sticks individually so had put that to the back of the troubleshooting list but looks like it could be a power problem with the RAM even though the mobo specifies the OCZ on the compatibility chart and not the g.skill.

Anyway I am leaving it idle until tomorrow afternoon to test, if all goes well I will give them my RAM and purchase myself a new set, then replace the original RAM under warranty and keep it for another build. This way the customer ends up with memory which cost over �100 where the memory they had installed cost around �55.

Hope it works for you mate, seems like a right bastard. You always find you do get a job like this once in a while.

It was frustrating but I am hopeful this has sorted it. Memory was the second component I moved too once the PSU was ruled out but after testing it thoroughly I moved onto the next steps. Customer should be happy too now they have a upgrade on their system spec and all of this work has been free of charge as goodwill even though my contract states if hardware is at fault and under warranty time spent diagnosing is charged. Thanks again to all members who had an input in this thread, was beginning to lose my mind so is nice to have some people to throw ideas back at me.

Fingers crossed mate . I have always found resetting cmos and only using 1 stick or ram normally removes these issues . Then ya can narrow it to just the ram . Ocz ya see ... Hit n miss for me , I always end up back with Corsair , I keep getting fooled by them fancy heatsinks :-)

I tend to buy G.Skill or Corsair, not sure why I went with OCZ for these builds but it was their gold series.

I've had dodgy ram pass memtest before - very annoying. Well done for having the perseverence to get to the bottom of it!

Looks like it, I emailed the client this morning to make sure as it's been 7days since I returned the machine but when I was there last Friday I told them to contact me immediately if anything happened.
