I have 768 MB of PC2700 DDR Ram and decided to add another 256 MB to see if I could get better performance in FS 2002. I know my motherboard can accept it but after I installed it my computer started behaving crazy and I was getting all sorts of error messages blue screens and all. I removed the added ram and everything went back to normal. I am using XP Home and I have an Athlon XP1900+ CPU with a GForce 4 TI 4600 Graphics card. I installed the same exact type and brand of ram that I have which is kingston.The sytem recognized it fine but it just went nuts!!! Any help would be appreciated.
