Q: Are these ECC or server RAM?
A: No — these are standard non-ECC unbuffered desktop UDIMMs. They will not work in servers that require RDIMM/LRDIMM.
Q: Will these work in a laptop?
A: No. Laptops use 260-pin SODIMMs. These are 288-pin full-size desktop modules.
Q: Can I mix the Samsung and Crucial sticks?
A: Yes. Both are JEDEC-standard DDR4-2666 CL19 at 1.2V and will run together. For dual/quad-channel setups, use matching pairs or sets per channel when possible.
Q: Will you split the lot or sell fewer?
A: This listing is for all 23 modules as a single lot.
