Hello,

I have a Dell Optiplex 380 MT with a 4GB Kingston DDR3 1333 PC3-10600 Memory RAM.
I searched for it and saw that my motherboard can support up to 8GB memory RAM so I bought another 4GB RAM here (https://ebay.to/2EjzcIl) but when I put the 4GB RAM along with the 4Gb i had before the screen load up then displays a black screen with a blinking cursor on top, I waited for hours still the same black screen.

So, i tried to remove both the 4GB RAM and tried to put only the one i bought and it displays the black screen but when i put back the one i had before it worked.

i even tried to change the slots but still black screen.

P.S: Using latest BIOS A07

@william p thanks for your reply

just want to know how to determine between low density 512x64 and High density 256x128 types?

on both the 4GB RAM i have - the one i had before and the one i just bought is written 1.5V KVR133D3N9/4G

but the one i had works perfectly but when i replace it with the one i just bought i get a black screen with a blinking cursor sometimes it is written press f1 to continue, f2 and f5 to diagnostics but when i press nothing works, it stays like this for hours.

Please help
