This spec page lists 128GB of 2666 RAM as compatible and knowing the price difference might be the most cost efficient upgrade. Now is 3200 a huge difference compared to 2666, slightly but not a noticeable difference in my experience. This web page at allthedifferences may help.
Hi there I'm new to the forum, I'm here today for a quick advice. As per the title, I'm planning on upgrading my RAM memory to 128GB on my mobile Precision 7750. Now, I currently have 64GB (non-ECC) [NAME] MHz, but just a single stick of 32GB [NAME], non-ECC is crazy expensive!   However, I found a good deal for 64GB (2 × 32GB), non-ECC [NAME], and I was planning on buying two of them, then upgrade the RAM on my machine.   The question is, is there any substantial difference in having 128GB [NAME] vs 128GB [NAME]? What I normally do is data analysis on genomic data, and most tasks are heavily reliant on RAM; in fact most often information are fully loaded on the RAM, and only once the execution is completed files are generated on storage memory.   Let me know what I should do, also considering the not negligible difference in price. Going for the option [NAME] would result in a saving of ~700$! Thanks in advance.   FYI these are the specs of my machine [IMAGE]
