I have a Dell Studio XPS 435MT, i7 920. I really love my machine and figured that I would upgrade the RAM from 6GB to 24GB. Loaded the RAM fine, BIOS says 24GB, ran the BIOS diagnostics with no issues. CPUZ tells me 24GB Triple channel memory. However, WIN7 Home Premuim list 16GB. Do I need to do something with WIN7 to get it to see 24GB?
