Hi all,

Here is the scenario. Brand new computer. gradually it is crashing more often. I'm reading that it may be the bios memory timings need to be addressed manually.
Chipset

I'm reading some info about recalculating the timing however I don't fully get it yet. I'm also unsure how to save the bios initially in order to make changes that I can revert back too. I would rather contact the person who built it.

From CPU-Z, this is what the application is reporting:

I am running kingston ddr3 1333 2 2GB sticks.

The system crashes and freezing are less now. I used an MSI live update thinking it installed new drivers. It did not. So, I updated the bios amongst other settings. duh!!!

MSI has a graphical "Control Center" they call it. All the DRAM timings and OCgenie settings are ready to go much like adjusting it in a control panel. Voltage and everything. I'm tempted not to mess with it.

The system isn't sluggish so if it works best not mess with it too much. I set up a ready boost flash drive and most applications are running at the level of no complaints.

If there is an article about RAM timings anyone would recommend please send my way. I'm confused about the calculations for timing and voltage. Thinking of pressing the OCgenie and going with some preset overclocking to see if it resolves some issues. But no matter what everyone says about how great OCgenie is , it isn't under warranty so, I'm hesitant to mess with it.

Again, thanks for the info.
