So my 6 year old laptop is struggling to handle CNN news sites for some random reason I'm using almost a Gigabyte worth of ram in CNN news site on chrome. I find this Atrocious, But there's the upside I have an old junked laptop with similar ram there both SODIMM DDR3 This laptop clocked at 1600Mhz the old laptop 1333Mhz and I looked it up and for DIMM if you have 3200Mhz and 2400Mhz (or any ram clock) and you could mix and match speeds because the faster ram would have to slow to keep pace with the slower stuff so dose it work with SODIMMS Ill give the brands in the chat. And I am mixing modules an 8gb and a 4gb ill post the brands later.
