Hello! 7050 has the Intel chipset Q270, that means if a higher frequency ram it works, I would do it at a maxim frequency 2.4 ghz due the chipset limitation. Regarding to memory amount, you should know how many ram you need, that you can see at Task manager when you run your heavier applications. Once this number known, and taking into account a bit more, buy the amount you think suitable. 7050 allows 2 x 16 gb without issues. And always, dual channel, that improves a lot the Intel UHD 630 integrated graphic performance, I've a 3060 with 1x16 gb, then I tested it with 2x8 gb, integrated graphic performance was almost a 40% better in Passmark Benchmark. Regarding to storage, I prefer a good NVMe for system and applications and a cheap but massive HDD for storage. Best regards.    
Hi, I am a user of Optiplex 7050 SFF (Small Form Factor)I'd like to update DDR4 RAM and storage. 1. What is the maximum RAM clock speed should be used that is going to be compatible with the PC, especially motherboard and CPU?Is it 2400 MHz? can't I use 3200 MHz?2. Current the PC has 8 GB (4GB x 2 EA), and is it ok If I add 32 GB more (16 GB x 2 EA)?3. In addition, Can I additionally use NVMe SSD as second drive?Is the motherboard has enough cable and slot to support it or do I have to just use one drive? I'm looking forward to receiving your reply soon. Best Regards,
