Quick Answer
Krugersdorp PC builders after a DDR5 RAM kit should order through Evetech, where 16 GB DDR5-5600 dual-channel kits (2x8 GB) are currently stocked from around R900–R1,400 and 32 GB DDR5-6000 kits (2x16 GB) sit in the R1,600–R2,800 range. DDR5 is required for Intel 12th gen and newer and all AMD Ryzen 7000/9000 series CPUs — you cannot use DDR4 on these platforms.
DDR5 vs DDR4: When Does Speed Actually Matter?
DDR5-5600 delivers roughly 8–12% better gaming fps compared to DDR4-3600 in CPU-bound titles on Ryzen platforms, according to platform-level benchmarks. In GPU-bound scenarios (most games at 1440p or 4K), the difference is negligible. The largest performance gap is in the Ryzen 7 7800X3D — its 3D V-Cache architecture benefits from faster memory bandwidth, making DDR5-6000 or above the recommended spec for AMD enthusiast builds.
Choosing Speed: DDR5-5600 vs DDR5-6000 vs DDR5-7200
DDR5-5600 is the baseline Intel XMP 3.0 spec and delivers reliable performance on most Z790 and B760 boards. DDR5-6000 is the AMD EXPO sweet spot for Ryzen 7000 — it matches the Infinity Fabric ratio for optimal performance without stability risk. DDR5-7200 and above requires tighter primary timings and a capable XMP/EXPO implementation to be stable; it's for enthusiasts who want to push the platform, not a recommended first buy.
Capacity: 16 GB vs 32 GB
For gaming in 2025, 16 GB dual-channel (2x8 GB) is the minimum for smooth multitasking while gaming. 32 GB is the recommended upgrade for content creation, streaming while gaming, or engineering workloads. If you're running OBS for streaming alongside your game, 32 GB avoids the memory pressure that causes stream drops. Krugersdorp gamers who use their PC for work too should default to 32 GB.
FAQ
Do I need to enable XMP/EXPO after installing DDR5 RAM?
Yes — DDR5 RAM ships running at the base JEDEC speed (typically DDR5-4800), not the advertised speed. Enable XMP (Intel) or EXPO (AMD) in your motherboard BIOS to activate the rated speed. This is a one-time setting that requires a reboot. Without XMP/EXPO enabled, a DDR5-6000 kit runs at DDR5-4800 — significantly below its rated performance.
Can I mix DDR5 speeds in a dual-channel kit?
Mixing different DDR5 speed kits is not recommended. Both sticks will run at the speed of the slower module, and mixed-kit stability issues are common. Always buy a matched dual-channel kit (the 2x packs) from the same product listing for stable XMP/EXPO operation.
What's the best DDR5 speed for a Ryzen 7000 gaming build?
DDR5-6000 CL30 is the current sweet spot for Ryzen 7000 gaming builds. It matches the Infinity Fabric 1:1 ratio at 3000 MHz, delivering the best memory latency and bandwidth combination without requiring extreme BIOS tuning. Kits from established brands running DDR5-6000 CL30 are currently stocked at Evetech.
DDR5 RAM, boot into your BIOS and enable XMP or EXPO — DDR5 always ships at its base JEDEC speed (DDR5-4800), not the advertised 5600 or 6000 speed, until you activate the XMP EXPO profile manually.
