my system was running 512Mb of DDR RAM, i went out and bought a 1Gb of ram, thinking this would give me 1.5Gb in total, but when i installed the 1Gb, my computer wouldn't boot up. so i swapped the 512 for the 1Gb and its working fine. both work individualy, why cant i use both at the same time?

Click the link below, and run Crucial's 'Scan My System' button. It will tell you what RAM you have installed, how many free slots you have, the maximum capacity of RAM that your motherboard can handle. It will also identify the type of RAM that your motherboard uses.
Of course, you don't have to buy any RAM from Crucial, but you can make a note of what information they give.
As for why your 512Mb RAM module and your 1Gb RAM module don't work together, it may be, as someone has already stated, that you need to use two RAM modules of the same size, or it may be that you have a low density module and a high density module. See what Crucial say.

Your avatar looks like a picture of a joke my friend sent me.
About the ram, most computers configured in such a way that you have to install ram in pair. Meaning that you either put in one 512, or 2 256s to make 512. If you want 1 GB, you'll need 2 512s, or 1 GB. If you have 1 GB, that's it you can only use 1 GB. Or you can buy one more and put 2 1 GBs to make 2 GBs. Hope that clears your understanding.

Depending on the motherboard you are using it may only support up to 1gig max memory, if it supports more, then its most likely to be clocked at a different speed, have a different CAS latency etc, its all ways best to put in a matched pair of memory sticks, then they work in sync with each other with no problems, its a bit hit/miss mixing different types/makes of memory, hope this helps.

Better still let us know the brand and model of your computer (or the motherboard if you have a custom built pc), and then I can tell you exactly which part you should get that will be compatible.
