Can you provide more details about your RAM modules?
- model name/ID
Is it ECC or non-ECC RAM?
its not bad ram
Depending on the chips actually used on your modules you may have a compatibility problem.
Have your cleared CMOS yet (with main power plug removed from PSU)? Sometimes
that is all it takes to solve problems like that.
I just build my first pc everything is connected correctly.
Take the mainboard of the case and put it on a non-conducting surface (cardboard or anti-static bag) and try barebone configuration only:
- CPU (reseat CPU and heat sink)
- one RAM module in Slot 1 (try different brand of memory as well)
- graphics card
- PS2 keyboard
- no hard drives, optical drives, add-on cards, USB devices and USB front panel connectors
- check all power connections on your mainboard (especially +12V CPU connector (4/8pin and 24pin main power connection) and make sure your graphics card is connected with the 6-pin +12V PCIe plug of your PSU
- clear CMOS with main power plug removed after hardware changes
See if there are any changes.
