I want to install some new RAM into my Dimension 4300 and from what I have been reading is that in the BIOS you should be able to set the CAS level to match what your RAM is. I cannot find this in the BIOS for my computer. Is this something Dell has chosen to leave out, or where do I need to look or is this something that I cannot do? Thanks for your help and if you need any more information, please let me know!
