I own an Intel DP55KG Extreme series Motherboard. However i am having some issues with the RAM
I have 2x 2gb sticks of the Kingston - KVR1333D3N9/2G of RAM rated at 1.5v. For quite a while now (1 year +) , i have been running them in Slots 3 & 4. Just today i wanted to run them in dual channel mode which is the 2 blue slots (Channel A & B , DIMM 0) however i get an Error 21 on the mobo and it beeps 3 times and boots up again. I tried running the 2 sticks of RAM in Slots 1 & 2 but i get the beep errors ( 21 error). I then tried the same sticks in 2 black slots (Channel A & B , DIMM 1 channel) shows the same 21 error and beeps thrice. But it works perfectly in slots 3 (blue) and 4 (black) ( Channel B , DIMM1 and Channel B DIMM 0) but doesn't boot up in slots 1 and 2 ( which is Blue ; Channel A DIMM 0 and Black ; Channel A DIMM 1)
i wonder what is actually wrong.. can someone give me an insight on this? and what i am doing wrong?
any help would be appreciated ):
also i ran a memtest86+ on both the RAMs in slots 3 (blue) and 4 (black) ( Channel B , DIMM1 and Channel B DIMM 0) and it showed no errors
