Running RAM in dual-channel (two sticks)

What it does
Using two matched memory sticks so RAM runs in dual-channel, instead of a single stick running in single-channel.
The honest verdict
This is a real, measurable FPS lever — the kind a registry tweak only pretends to be. Two channels roughly double how fast the CPU can move data in and out of memory, and games lean on that bandwidth, especially when the CPU is the limit and dramatically on laptops and APUs that borrow system memory for graphics. A single stick can cost double-digit percentages of average FPS and hurt your 1% lows even more, so the frames stutter. Match a second stick to your first (same capacity and speed), seat them in the slots your motherboard manual marks for dual-channel, and switch on the rated speed profile (XMP/EXPO). The cost is one stick of RAM; the gain shows up on the frame counter.
How Compy treats it
Where it genuinely fits a rig, Compy can recommend it — applied with a snapshot first and a one-click rollback after, like every change it makes.
The Compy Blackbook holds 174 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
