You will continue to have warranty on the system with the configuration you bought from Dell. If something breaks, and it may be RAM related, best option is to put the original RAM back and then call Dell for support under warranty. Replacing your original RAM or harddisk won't void the warranty on your fans of screen for example.
Be aware that the 7520 is extremely picky on memory modules at 2666 MHz. I used 3rd party RAM to upgrade mine from 16GB to 32 GB and it failed. Then I had a chat with Dell support and they recommended me a Dell part number but it also failed to work. I ended up having to buy 2 extra modules with exactly the same part number as the ones I already had in my system and Dell did not sell these. I found them at eBay and they work fine since.
I don't recommend going to 64 GB RAM at 2666MHz if Dell does not support it since I am afraid that it probably will not work. For 64 GB RAM, go with the Dell recommendation and use their recommended 2400 MHz modules.
Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.
The Dell spec sheet says this about RAM: "4 DIMM slots: up to 64GB DDR4 NECC 2400MHz Up to 64GB DDR4 ECC DDR4 2400MHz Up to 32GB DDR4 2667MHz SuperSpeed memory"
If you are upgrading to 64GB, as long as the price is good... Just get the Dell 2400MHz RAM. You might end up with some compatibility issues installing 64GB of faster memory.
For your NVME drive upgrade, you might want to look into using the 2.5" bay. That is unless you already have a 2.5" drive installed. The 2.5" bay uses a cable that includes SATA, 2x PCIe lanes, and power pins. You can get an interposer board that converts the bay into a NVME compatible m.2 port.
Ok, the first point. I agree the original specs do say 2400Mhz. But in case I buy 2666Mhz. I doubt it would be a problem because I am going faster and not slower in the RAM specifications. My guess. Also the Kingston RAM Matching tool or whatver does show 2666Mhz, when I enter my workstation model number. So I thought better to go with 2666 instead of 2400. But if you recommend that, I am fine with it. Might save me additional money when I buying from outside
However, the moot point was, will the warranty stick?
As I said, Dell has given a no-regret price of 71K INR while I am getting that in open market at 19K INR ! Whatever the currency, the difference is too big to be allowed. For better understanding, if I convert it to USD from INR; Dell has quoted 962USD while I am getting it at 257USD! Same brand, same warranty, same everything!
About the Hard disk, yep, I am already used up the 2.5" bay. I have a Micron Eco 7.68 TB on that.
I am a travelling techie and work a lot on VMWare workstation for trials, temp virtual machines, etc. for my customers. So for e.g. I am at a customers place, I just fire up the Workstation, Deploy a VM, demonstrate to the customer and once the customer understands the deployment, I delete it. Sometimes, I have to boot upto 3-5 different VMs in the same laptop to demonstrate some capability to the customer. Thats the reason, I need 64GB RAM and also the faster class 50 NVME increased to 2TB. When I bought the machine, 2TB NVME was not an option so couldnt buy at that time. The 2.5" doesnt give me that speed when I am working on concurrent VMs, though I do fire up one or two of the VMs on that, but nothing compared to the NVME.
