RAM upgrade problem :(

[studor97]

I recently got another 4GB of RAm for my PC. Its exastly the same as my other stick of RAM (Corsair 1333mhz). I installed and my PC turns on but there's no display. But when I take 1 stick out and leave 1 in, my PC boots fine. I tested to see if the new RAM was faulty so I took my old one out and lefdt my new one in and it boots up fine so the new RAM isn't faulty. I need help please,

Thank you.

P.S, my specs are:

 

AMD A6-5400K

asrock fm2a75m-dgs motherboard

 

Thank you.

i think they should have the same CL as well as MHz. Are you sure they are the same product, with the same code?

do you have two other random ram sticks ddr3 in your house any mhz or gb

also it seems to be a motherboard problem are you sure they ar the same sticks

is it possible you simply have more ram than is acceptable? on crucial.com they have an upgrade tester utility that will tell you exactly how much ram you can use

Try various combinations of the ram slots on your board.  Then if that dosnt work id go into the bios and configure all the memory settings.  If that still dosnt work, unclock your memory, maybe 1066mhz...see if that does it.  Also ive never had issues with mixing memory (maybe it was just luck) as far as clock speeds and timing goes.

Yes

Moglakos there exastly the same RAM

The first time I put both RAM sticks in, they worked. I went on a game and my display turned off with my keyboard, mouse and headset. I turned it off and back on again and my PC turns on but theres no display.

Are you getting any error codes on your motherboard with both sticks?

[studor97]

What do you mean, when both RAM sticks are installed, my PC turns on buts there's no display at all.

Hmm, since both sticks work alone from one another it does sound like a motherboard problem. I'd try resetting the CMOS with both RAM sticks in, then if you get display go into your BIOS and make sure your motherboard has detected all your RAM.

OK ill try that, do I take the CMOS battery out?

yes or if your mobo has a clear cmos button than that would work
