I'm using these...

Ripjaw's F3-12800CL9D-4GBRL - http://www.gskill.com/products.php?index=222

The motherboard I'm using is not listed under its "Qualified Motherboards List". Mobo is GIGABYTE GA-P55M-UD2 - http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=3165

Could this be one of the reasons as to why my computer keeps locking up? [no BSOD though]

update :

- memtest ran fine
- all speeds are properly set in BIOS for ram and CPU

I tried to run the computer by removing one memory stick and only leaving one 2gb ram to test each ram individually.

however, when I power up my pc w/ only 1 ramstick, it doesn't boot! lights just come on on the mobo and it's like as if there's no feed to monitor. is this normal?

yup, i'm at stock cpu....i don;t oc, and it happens randomly even while i just surf the web [no gaming, etc].
 
it very well could be, you need ram that states it has a profile for P55 otherwise it requires to much voltage from the cpu's memory controller causing frrezing, that or windows corruption could be the culprit
 
The Ripjaws are made specifically for the Intel low voltage requirement.

Have you tried running them at lower memory speeds?
Have you ran memtest?
 
I haven't tried running at lower memory speeds.

I just did a memtest for two hours ; ran fine with no errors...

if i looked at gigabyte's website for supported memory under that mobo, the ripjaws ram is actually listed as supported.

checked by bios and it running at around 1.5v
 
Just because you can pass memtest doesn't mean the cpu/memory have enough volts to be stable in windows. Been there.

Lower the memory speed to be with in Intel spec for supported speeds, or anything 1333 or less. Also, make sure you timings are right too. They have a 2T, and not 1T like most people think including myself initially.
 
I'd just like to add this....

Whenever my computer locks up, here's what observed....

The lights that are usually solid on my mobo where the ethernet port is, goes off.

could this be a power supply issue?

======================= freeze ups still occur
