Hi, I am considering buying Dell Precision 7730 and 7740 workstation laptops. However, I want to upgrade them with more RAM memory. Currently both of them have 16 gigs for ram running at 2667 shown in task manager area.

I read on Dell, that these can take ram sticks UpTo 3200. But the seller I am getting these laptops from said; We don't know why but even if you upgrade the RAM sticks that has 3200 speeds, still they will be downclocked to 2667.

At this point I have a few questions:

1. Is this bios problem.
2. Do these laptops take/accept only certain brand of RAM that would actually run at 3200?

I will appreciate responses if anybody here has had the same issue and successfully has figured it out.

Thanks to everybody who responded to my last post, I was actually surprised the prompt responses I got on my last post here.

Help Needed.
 
it can take ram with 3200, but it will run it at 2667
limit on the cpu.
Thanks for your reply. Is there a way to run the ram at 3200 at max speed. Possibly upgrade CPU? Or do some other setting in BIOS. Or I have to live with 2667 limit on the CPU?

Speed wise your stuck.

If you do upgrade the ram keep the dual channel feature in mind.

How many sticks of ram are in each pc now?
