Need help setting up ram and cpu settings

Crap. I right-clicked on my computer and only saw 4 gb of memory.

What operating system are you using? If you are using XP 32 bit it will only show you 4GB of memory, if you are using Windows Vista or 7 it should report the full amount of memory you have even if it cannot access it all.

You will want to go into BIOS and set your memory speed, timings, and voltages manually to make sure it is running at the correct settings.

I'm using Windows 7 64-bit. I went into BIOS and changed something to XMP or something like that. It automatically changed the voltages and the dram values to 1600. Is the Hyperthreading a bad thing to have enabled? My main purpose is gaming, but I do like to have multiple open applications at a time. They aren't like actual intense application software. It's just websites, maybe games, etc...

Leave hyperthreading enabled, it can help quite a bit in some cases. XMP is fine, its a slightly overclocked profile put on by the manufacturer but its known by them to work fine for that kit.

The other one was DOCP where the cpu and ram was set to 3146/2006mhz. It was scary though. the dram voltage automatically set itself into a danger zone. It was red at 2. I was scaling it back, but I definitely didn't want to mess with it. I'm not sure if it would've worked anyways. It even indicated that the motherboard could be damaged.
