BSOD After using ASUS Sabertooth 990FX MOBO OC Utility.

No worries mate! You're welcome

hi huonub
Sorry for the delay! Just woke up

While everything is at it's default's if you follow this guide but set your ram to it's specced timings from the label of the memory sticks manually
Crosshair V Formula Easy Memory Setup Guide The guide is for the Crosshair v Formula but it's pretty much the same.
Then run memtest86 and some sort of stress test for the cpu like Intel Burn test or AIda64.
Download IntelBurnTest - MajorGeeks
Downloads | AIDA64 the portable version is fine.

If you have no crashes and you're sure you system is stable at its default settings then you can move on to overclocking.

There is a good guide for Bulldozer here Crosshair V Formula & AMD FX 8150 CPU Overclocking Guide | Republic of Gamers
and here AMD Bulldozer and Piledriver Overclocking Guide - Asus Motherboard

Have a good read through those to give you more of an ideal of what each of the setting's do.
Most Bulldozer cpu's will do about 4-4.2ghz on stock voltage.

Note in the guide from overclock.net it show's the HT link speed set higher than Cpu/nb. That is for Piledriver but Bulldozer prefers these to be set the same as eachother.
Anything you're not sure of just ask and i'll be happy to answer.

Edit: Remember that whenever overclocking there is always a risk of damaging components. If you can't replace it don't overclock it. Make sure you keep an eye on your temps and don't use more than one software to monitor the temps as it will cause missreadings.

I didn't notice in your system specs what CPU cooler you're using. If you're using the stock cooler, I would change to a third party cooler as soon as possible. Both the Intel and AMD stock coolers are junk. Always know you're CPU and GPU temps. Watch them like a Hawk during any stress testing. Temps will get very high, very quick. The stock cooler can't handle it.

That's good. I just didn't want you to try running CPU stress tests with the stock cooler.
