I just had this exact problem with the same ram and mobo, downgrade your mobo firmware to the 2nd newest, worked like a charm

It is possible that there is some Memory incompatibility here (as I have seen this before). slightly incompatible RAM will work on its own, however when the second stick is added the system won't start.

I find that KINGSTON provides reliable mem and they have a web tool with which you can search for the device that you have.
(where they have tested and confirmed that the specified memory works), I think this is great and have used it several times myself.

Hello i can't install a AGP 512 videocart I bought

your computer needs more than the video card ram amount to use a particular video card. if you do not have at least 512mb of system ram, that may be your problem. if you have sufficient ram, then you do not have a powerful enough power supply for the new card.

Problems with 3 brand new PC 133 512 MB RAM in Netvista 6794

That last RAM probably is good. Many motherboards have problems using many different memory. All of the memory you have should be at least identical to ensure that they work. When RAM run at different speed or require a little more voltage, they will not let your motherboard boot. You can try mixing up the order you put the RAM in. Try putting the last RAM in the first slot by itself, the motherboard should boot. Then try the rest.

Also, whenever you add or change hardwares, you should clear the CMOS/BIOS settings.

I want to upgrade my PC's RAM from 128 to 512 MB Is is possible to add only single RAM or two 256 MB RAM?

Depending on your mobo, you can do either, add one stick of 512MB or two sticks of 256MB. If you're sure you get matching sticks if your mobo is DDR capable.

How can i increase my ram in intel desktop board 815


Ram can not be increased as it is a hardware component in the computer, you can install more ram or upgrade the current ram modules that are inside the computer.

Upgrade from 512MB to 1GB

The specs on the memory are correct, so you purchased the correct type of memory for this motherboard. If your getting no video when you power on with the 1gb stick, I would be willing to bet the 1gb stick is bad. Can you return it and try another stick?

OS won't work with RAM upgrade

Hi !
if u wanna upgrade RAM ,ur RAM should be of same capacity in both slot. i mean to say if u wanna use 1 GB....then put 512 & 512 or else put single 1 GB. But u cant use 512 in one slot & 1 GB in another slot at a time. if u do the combination like that ,it will never work.

Can't Install RAM in DDR2 and DDR3 DIMM slots

You cannot use DDR and DDR2 ram at the same time, because its always been like that (ie, no SD and DDR, or SD and RIMM)

What you should do is switch to all DDR2 sticks.
