Query: Software issues after plug-in of DIMMs

Purchased qty 2 of the Kingston ValueRAM 1GB 533MHZ DDR2. I wanted to increase my server from 2G to 4G. I matched up the proper Gig and speed as the other two Kingston DIMMs in the server. The server showed that there was an increase of memory from 2 Gig to 4 gig, however, some of the applications on the server would not display properly. I had to remove the new DIMMs for my applications to work. I would not recommend these to anyone. Wish I had the money and time back that I spent on using this poor product.
