Compatability of Memory Upgrade
DDR RAM needs to be installed in pairs, as in if you have two 1GB sticks these would, in a four slot board, be inserted in slots 1 and 3 or 2 and 4. The other odd 512MB stick could go in any other slot theoretically speaking. But, you would be better off leaving it out. The SPD chips on the two 1GB sticks should match themselves to time at the slowest common or fastest common denominator.
There is a chance that by having the odd bank population that you said worked for awhile installed as you had, that the MB RAM slots were put under unusual voltage stess. There is a pretty good chance you can remove the 512MB stick, leave the two 1GB sticks in slots 1 and 3 or 2 and 4. But, this is VERY important: consult your board manual or access it online and read what the population requirments are for the slots as in some cases, the two matched sticks go in 1 and 2 or 3 and 4. This little oddity is found from time to time.
Consult your manual or download it and read how the slots need to be populated and stick with the two 1GB sticks.
There are memory testing programs you can find for free at majorgeeks dot com and test your RAM once you have it populated correctly.
In the future, I'd suggest you purchase RAM from Kingston or Corsair directly online as they usually offer a lifetime warranty and this RAM right now for you board is dirt cheap.
