Ram installation issue

[Danny__1]

I'm trying to upgrade my desktop's RAM from 2x2GB to 2x4GB. The model of the new sticks is Pacific Sun DDR3 (2x4GB) PC3-10600 1333M 240-pin DIMM Memory. I've tried all kinds of configurations for seating these new sticks.

When I have both sticks in I get the following black screen, and I'm stuck here. The computer doesn't respond to the keyboard at all. If I just try 1 of 2 new sticks, the computer will begin to boot, but will abruptly shut down at the windows booting screen. Both my operating system and motherboard (MSI 2A9C) are capable of running 16GB RAM, so I'm confused as to why 8GB is a problem. Any help would be appreciated.

Hi:

HP PC's with the first gen Intel core processors are very hard to find the right memory for.

Most likely the memory you bought is high density and density is not normally included as one of the specs.

I recommend that you return the memory if you can and purchase this brand/part number which should work for your model PC...

Hi Paul, thanks for the reply.

Could you go into a little more detail on what you mean by density? I want to be 100% sure that the memory I bought isn't compatible with my PC before I return it, because returning it would be very inconvenient. Is there any way I can test my computer's maximum RAM density?

You're very welcome.

These links will explain what memory density is.

I don't know of any way to actually test it...although I believe you just did in a way, since the memory doesn't work.

HP desktop PC's from that era use low density memory.
