Ultima ROG Infernus Overclocking Games Problem

[Soul Destroyer]

Hi,

After talking with support they suggested I posted here to try and get my problem sorted,
I just got the ROG Infernus system but sadly there has been a few problems.
The first 8 hours of gaming proved a nightmare as every game tried crashed after a few minutes.
After help from support we found that one of the cards seemed faulty,

So with one card the games still crashed after 10 mins of so, Again after support helping me adjust the voltage and a few other things this seemed to help a bit.
But the games all crash/freeze after 40 mins or so now.

Support suggests that maybe you folks or apac can help me out to fix this problem.

My system is supposed to be running at Intel Core i7 3820 3.60GHz @ 4.60GHz ROG DDR3 2133MHz

My settings for BLCK Frequency is 104.77
CPU VCORE VOLTAGE 1.386v MANUAL MODE
CPU VCORE MANUAL VOLTAGE 1.360
VTTT CPU VOLTAGE 1.150v AUTO
DRAM VOLTAGE 1.5000

Using the OC profile configuration OCUK

Any help would be appreciated thanks, as its a bit sad to spend almost 2300 on a system that keeps crashing.

Thanks
