Can you post the same screenshots again when you do overclock them?
Which slots are they in atm? Spd is sayings slots 1 & 2? Cpuz is reading dual channel so it must be correct. Usually on four dimm slot motherboards with two sticks of ram is slots 2 & 4, 2nd and 4th slot from cpu. Unless i saw the wrong motherboard?
Yes it's correct but what cpuz reads does not match the number printed on the motherboard. what you see in the screenshot is 1&2 but it's 3&4 (of blue color) on mb. I changed it to 1&2 (of white color) on mb and then cpuz reads 3&4.
It turns out though, it's the problem with the new stick. This time when I set the frequency to 1996, it wouldn't even pass the POST. but if I remove the new stick, the old one will run smoothly. and if I use the new one alone, it wont pass POST either. This stick will only work under 1866.
I'm not sure how in the beginning when I simply added the new stick and ran with the old bios settings it worked, only with cpuz showing single channel. I believe it was how it happened because I rebooted a couple of times in trying to figure out why.
Anyways I am returning the stick to seller already. and orderd another from a more reliable selller. I will come back and let you know what's with the new one, hopefully nothing weird will happen again. Thanks for your time and help.
