OK apperantly the price difference is less than I thought. However, my current set costs $65! I'm wondering what I could use to get 4GB more that's a bit cheaper. I don't really do overclocking. My current set is already running at 1333MHz, 1.5V, 9-9-9-24 timings. It's rated for 1600MHz, 1.65V, 9-9-9-24 timings. The sets I'm looking at are 1333MHz, 1.5V, 9-9-9-24 timings. Would there be any issues?
