I'm not a fan of mixing and matching rams in any platform. Zotac's boards are notorious for dying if subjected to having 1.65 volts or more from the ram. You should set the voltage to 1.5v as the max. Are you on the latest BIOS on your motherboard?

It is already 1.5 V right
And one more thing if you see in task manager screenshot
Itshow saying that 4 gb is hardware reserved

What version of Windows are you using? A 32 bit version will only allow 4Gb to be addressed, to use more than 4Gb you'll need to have the 64 bit version installed.

Try adjust timings manually in bios with the values listed in #4 jedec table.

10 9 9 24
Try as well command rate 2T

What exactly am I suppose to change from all of these

 

[boju]

Top 4. It's already set. Try

10
24 or 25
10
10

Command rate should further down the list. 1T or 2T. Try both.

Try as well dram 1.55v

I tried all the things but nothing is working

Try disabling Memory Remap Feature in BIOS.

Aahh well, you tried. The two sticks are just being uncooperative.

Maybe switch them around.

If still no it's bad luck. Mixing ram isn't guruanteed.

Memory is guaranteed in the form sold. Other combinations you choose to make have no guarantee to be compatible together.

You are free to do your own compatibility testing, however you may find it to be less expensive using a single kit that has already be tested and has a lifetime guarantee.
