Go to the Dell support page. Type in your service tag number. When your system page is shown click on the right side where it says system configuration. The details of your system as shipped will display.

Thank you, I really appreciate it.  I wanted to get this before I opened a new thread about possible upgrades. Thanks again!

Hello again, just got a fast answer to my last question by JOcean, really appreciate it!

My next question is, given the specs on my 8930, I'd like to upgrade it somewhat to make it perform better, it seems a bit sluggish now and then.  I used the Dell Support Site to run my Service Tag and this is what I apparently have:

XPS 8930 Base
Windows 10
9th Gen Intel(R) Core(TM) i7 9 700 (8-Core, 12MB Cache, up to 4.7GHz with Intel(R)
1TB 7200 rpm Hard Drive
16GB (2x8GB) DDR4 2666MHz Turbo Boost Technology)
BDRE
Killer Wi-Fi 6 AX1650 (2x2) an d Bluetooth 5.0
WAVE MAXXAudio Pro
UHD Graphics
Dell UltraSharp 27 4K USB-C Monitor

I know I can add RAM, just not sure what a safe maximum would be. Also, I'd like to upgrade the chip to a faster one, if it's cost effective.  Additionally, I'd like to get a really good graphics card to make the most of the UHD monitor I have and lastly, I've tried getting the Blu-Ray player to run UHD discs but it keeps telling me my equipment is wrong...I have Cyberlink Power DVD 20 and Power Media Player BD for Dell, but neither can run a UHD disc properly.

I'd like to ask opinion on what some very good upgrades might be for adding RAM, faster chip, great graphics card and UHD disc software for the BDRE.

Thanks!

Happy to help out!

Are you certain you have a blu ray DVD drive? Is it external or internal? I don't thing the optional dvd drive that came with the computer was for Blu ray. Also you need Blu-ray player software. DVD support is on its way out nowadays.

Upgrading the cpu is not a practical idea and would not make much of a difference--besides being very difficult to do. Consider a SSD drive instead. However-- as of now you will not be able to upgrade to Windows 11. Your model is not approved for upgrading. to windows 11 so any expensive upgrades now would be a waste. Use it as is now and wait until Windows 11 comes out probably by Jan 2022. 

You already have a very good cpu right now i7-9700.  It is not a slow cpu at all by 2021 standard.  Your perception of slow pc is not due to cpu.

an ssd is good idea to speed up your pc. Either 2.5 sata ssd or M.2 ssd.  2.5 sata ssd is more cost effective.

16gb ram is pretty good for most business application and gaming.  Your “slow” pc is not due to ram unless you are doing 100 tasks at same time such as opening 30-50 chrome tabs or doing video content rendering.  If you are not using your pc as a professional workstation, no need to go beyond 16 gb.

a discrete graphics card is better for gaming.  If you just want high resolution display, the UHD630 integrated with i7-9700 is already very good.

The i7-9700 operates at a 3 GHz with a TDP of 65 W and a Turbo Boost frequency of up to 4.7 GHz. This chip supports up to 128 GiB of dual-channel DDR4-2666 memory and incorporates Intel's UHD Graphics 630 IGP

Also, if you are concerned about Windows 11 compatibility, based on link provided in 1st reply, your pc is good.

XPS Desktop

The following list of Dell XPS desktop computers that will be tested for upgrade to Windows 11. If your computer model is not listed, Dell is not testing the device, and drivers will not be updated for that model.

• XPS 8930
• XPS 8940

I have the same CPU and amount of RAM in my XPS 8930. I also have a 512GB SSD and a GTX 1660Ti video card, (DVD drive instead of the optional BlueRay drive).  With those differences, I don't think this PC is slow. It boots up and runs apps fast, but I don't game.

Keep in mind Intel UHD Graphics hogs both CPU time and system RAM, so an add-in video card with its own graphics processor and RAM would free up your CPU and system RAM for other tasks. So that might be at the top of the upgrade list, maybe ahead of an M.2 NVME SSD.
