  2. I put the ram only using slot A and my pc suddenly shutdown after 24 hours give or take...
  3. I also try put the ram only on slot B but the won't boot quite a few times and after got boot up... my pc hang after a few seconds finish loading the windows...
  4. is it my mobo slot damage? or my mobo is starting to dying?

my pc spec

Could you tell us your motherboard and what RAM your putting in? The CPU and GPU are a bit useless in solving this from what I know – Simon Sheehan Feb 1 '12 at 3:30
my mobo is ASUS M3A78 Pro my rams is corsair gaming memory 2gig each – Dark Prince Feb 1 '12 at 3:33
sorry i just a beginner about pc hardware... – Dark Prince Feb 1 '12 at 3:35
"corsair gaming memory" is also very generic, do you have a more exact model? – Simon Sheehan Feb 1 '12 at 3:51
Sounds like a pin contact problem. Use a small paint brush or bulb syringe to clean the DIMM slots and then use an eraser to clean the contact pins on your RAM. Then get a bootable CD with memory testing software (like most Linux LiveCDs) to test your memory. If you have handled them with much static electricity on you before, they may have already been damaged. – Feb 1 '12 at 3:55

First things first. The manual mentions how the DIMMs need to be populated in Single/Dual channel mode. There's also a QVL (Qualified Vendor List) check your exact memory model/part number in that list.

Memory Configuration

to tell the truth... i dont know anything about that.... – Dark Prince Feb 1 '12 at 4:41
adding, sometimes going Dual channel , the memory can get more pickey, and sometimes adjusting the timing can "fix" that. doing some memory testing and tweaking might be in order, especially if its not on the almighty compatability list :-) – Psycogeek Feb 1 '12 at 4:44
okay... so how to tweak it? – Dark Prince Feb 1 '12 at 4:55
Check your BIOS settings for memory timings and voltages. Try with all memory settings at defaults first. – David Schwartz Feb 1 '12 at 5:57
It sounds like that level of stuff may be over his head. – Synetech Feb 1 '12 at 6:25

If it were a “normal” problem like incompatibilities or incorrect configuration, then the erroneous results would be more consistent than what you described. Also, you said that a mem-test gave you no errors (how long/how many passes did you do), so chances are that nothing is damaged if it does indeed work. From the description you gave, I agree with; it does sound like a contact problem which would give the intermittent (ie random) errors you are getting.

What I would recommend is to shut everything down and pull the plug (don’t just turn it off), then use a standard pencil eraser (not a hard one) to wipe off the pins on both sides of the RAM modules (and of course wipe off the rubber shavings). Next, use an old toothbrush to lightly brush the RAM slots (perhaps breathing onto them to add a slight bit of humidity).

If that does not do the trick, examine the pins on the RAM sticks. Do they look clean and shiny? If not, try repeating the cleaning. (I have in the past even resorted to using an emory board/cardboard nail file—to lightly scrub the pins on the sticks and in the slots.)
