Choosing among desktop CPU platforms, replacement boards, and DDR5 desktop memory is a fit problem first: a socket mismatch can matter more than a lower price, and a memory module cannot substitute for a motherboard. For cpus, motherboards & memory, identify the target machine or build path-Dell XPS 8940, Dell Precision 3650, AMD AM5, or a DDR5 upgrade-before comparing condition, form factor, and price.
Quick take
Each item has a different job:
- Dell XPS 8940 Desktop Motherboard: The direct board-replacement path for a Dell XPS 8940 system.
- Dell Precision 3650 Tower Motherboard: A model-specific route for a Precision 3650 tower.
- G.SKILL Ripjaws S5 32GB DDR5 Memory: A memory-led upgrade centered on one 32GB module.

Listed-price comparison
The prices span distinct upgrade categories, so socket and product type should come before cost. The absolute listed-price spread is USD 289.01, from the Dell Precision 3650 board to the G.SKILL memory.
| Product | Listed price | Price bar | Fit described |
|---|---|---|---|
| Dell XPS 8940 Desktop Motherboard | USD 161.58 | Dell XPS 8940 board path | |
| Dell Precision 3650 Tower Motherboard | USD 89.99 | Dell Precision 3650 board path | |
| G.SKILL Ripjaws S5 32GB DDR5 Memory | USD 379.00 | DDR5 desktop memory path | |
| MSI B850 GAMING PLUS WIFI6E Motherboard | USD 134.99 | AMD AM5 gaming board path |
Decision matrix
Use this order when narrowing the choice:
- Target machine: Match the Dell XPS 8940 name with the XPS-named board and Dell Precision 3650 with the Precision-named board; the two Dell boards are not interchangeable by model name alone.
- Build type: Choose the MSI entry for an AMD motherboard build, or the G.SKILL entry when the job is adding desktop memory rather than replacing a board.
- Condition: The Dell XPS board is New, the Precision board is Used, and the MSI board is Open box. Treat that distinction as a decision factor after platform fit.
- Price role: The table shows a USD 289.01 spread, but the lowest-priced item is still a model-specific motherboard and the highest-priced item is memory, not a competing board.
Product notes
Dell XPS 8940 Desktop Motherboard
Choosing the Dell XPS 8940 Desktop Motherboard makes sense when the target machine is an XPS 8940 with a 10th- or 11th-Gen Intel Core processor. The LGA1200 socket and H470 chipset give that fit a clear boundary, while New condition is also explicit. Ports named include M.2, SATA, PCIe, RJ-45, USB 3.1, USB 2.0, USB Type-C, and headset. The limitation is platform scope: its compatible-model wording centers on the XPS 8940, so it is not the AM5 board or the DDR5 memory item. Choose it when the Dell model match matters more than a cross-platform build.
Dell Precision 3650 Tower Motherboard
The Dell Precision 3650 Tower Motherboard is the direct fit for a Precision 3650 board replacement. Its LGA1200 socket and DDR4 SDRAM identify the intended memory and socket path, while BIOS Unlocked, Computrace Unlocked, and MDM not enabled add concrete configuration details. The limitation is Used condition, which separates it from the New XPS board without establishing a performance result. W580 and Precision 3650 naming keep the choice model-specific rather than a general AMD build. Choose it when that Dell tower match is the priority and the DDR4 route is appropriate.
G.SKILL Ripjaws S5 32GB DDR5 Memory
G.SKILL Ripjaws S5 32GB 1x32GB DDR5 6000 CL32 XMP 3.0 Intel Desktop Memory is the memory-focused purchase here, not a board replacement. Its 32GB single-module format, PC5-48000 (DDR5-6000) bus speed, CL32, XMP 3.0, unbuffered non-ECC design, and 33mm low-profile heat spreader provide a precise target for a DDR5 desktop memory upgrade. The limitation is scope: the title identifies one module, so it should be matched with a system using DDR5 memory rather than an LGA1200 Dell board. Its USD 379.00 price is also the highest listed, a reason to reserve it for a memory-specific need.
MSI B850 GAMING PLUS WIFI6E Motherboard
MSI B850 GAMING PLUS WIFI6E AM5 AMD B850 SATA DDR5 Motherboard is the AMD route for a gaming build centered on AM5. It is specified for Ryzen 9000, 8000, and 7000 processors and includes an ATX form factor, four DDR5 DIMM slots, and a PCIe 5.0 M.2 storage slot. Together, those details define its expansion and platform brief. The limitation is Open box condition, and AM5 places it on a separate socket path from both Dell boards. Its 256GB memory ceiling and 8200+ MT/s OC figure are platform specifications, not a guarantee for every kit.
Final recommendation by use case
- XPS 8940 replacement: Choose the Dell XPS 8940 Desktop Motherboard because the XPS 8940 model phrase, LGA1200 socket, and New condition align with that specific Dell target.
- Precision 3650 replacement: Choose the Dell Precision 3650 Tower Motherboard when its model-specific wording, DDR4 SDRAM, and unlocked BIOS and Computrace details fit the repair path.
- AMD gaming build: Choose the MSI B850 GAMING PLUS WIFI6E Motherboard for its AM5 socket, AMD B850 platform, ATX form factor, and Ryzen 9000, 8000, and 7000 support.
- DDR5 memory upgrade: Choose the G.SKILL Ripjaws S5 when the 32GB 1x32GB format, DDR5-6000 specification, and XMP 3.0 are the target; it is a memory purchase, not a motherboard.
