How do you choose your RAM?

[justr]

Hi All,

actually that's a question that's been bugging me for quite a while now, too.
I built two systems last year and for both I got a good quality mainboard and RAM. Unfortunately on neither of those systems I can get the RAM to run at more than 1066Mhz.
I've been searching my a.. off on the internet to find some explanation. Unfortunately the only answer I got was that it possibly had something to do with the cpu being "locked"?????

I'm still pretty new to all the CustoMac stuff, but I built my share of PC systems over the years. I never had problems like that before.
Maybe someone here can explain to me, why I can't get my RAM to run properly.
Here are the specs of my systems:

Mainboards:
- Asus P6T
- Gigabyte GA-EX58-UD5

CPUs:
- Intel Core i7 920 2.66 Ghz, LGA 1366
- Intel Core i7 930 2.80 GHz, LGA 1366

RAM:
- Corsair CMX6GX3M3A2000C9, 3x2GB, DDR3-2000, [email protected]
- Mushkin REDLINE 3x2GB Kit, DDR3-1600, [email protected]

Any idea what I'm doing wrong?
Thx.

You change the RAM speed in BIOS-- usually by changing the RAM multiplier to a higher number. But if you do this, you should definitely test using Memtest (google it) for an extended period of time.

See this guide: http://www.techreaction.net/2010/09/07/ ... -gulftown/

Thx for the link.
I'm gonna give that guide another try. Maybe I've been overlooking something essential.
I've been playing with the BIOS settings for weeks/months, but couldn't find any settings that would leave my system stable.
I must do something wrong, but just can't figure out what it is.
