4 Things to Know About the Dell XPS 8930's RAM Slots
The motherboard has four DIMM slots for memory expansion. This gives you room to add or upgrade RAM without replacing existing sticks.
Fill only two slots for dual-channel memory performance. Using two matched sticks in the correct slots maximizes speed for most tasks.
Keep the remaining two slots empty for future upgrades. This lets you double your RAM later without discarding current modules.
Avoid mixing different RAM speeds or capacities in the same channel. Mismatched sticks can force all memory to run at the slowest speed.
