DDR4 Upgrade Kits compatibility checklist should be shortlisted around the job it must do. South African buyers should compare fit, performance, compatibility, and upgrade room, warranty path, and upgrade room before treating any pick as best.
Before ordering a DDR4 upgrade kit, confirm your motherboard uses a DDR4 socket (AM4 for AMD, older LGA1200/1700 DDR4 boards for Intel), that the kit's speed is supported, and that you buy a matched dual-channel pair. A DDR4 kit pairing CPU, board and RAM typically runs around R5,000-R9,000. DDR4 and DDR5 are not interchangeable, so check the platform first.
First, confirm the platform is DDR4, not DDR5: AM4 boards and older Intel DDR4 boards take DDR4; current AM5 and many newer Intel boards require DDR5. Second, check the supported RAM speed (commonly DDR4-3200 to 3600 on AM4). Third, buy a matched 2x8GB or 2x16GB kit for dual-channel. These ensure the kit works.
A DDR4 upgrade kit is a cost-effective route to a capable system, since DDR4 and AM4 parts are mature and affordable. For 1080p gaming and everyday work, a DDR4 platform performs well at a lower cost than moving to DDR5. Just confirm your board and CPU choice are DDR4-based before ordering.
Enable XMP/DOCP in BIOS so the DDR4 runs at its rated speed (often DDR4-3200 or 3600) rather than a slow default. Buy a matched kit on your board's QVL, and on AM4 favour DDR4-3600 CL16-18 for the best balance with Ryzen.
Only if your board has DDR4 slots, AM4 or older Intel DDR4 boards. Current AM5 and newer Intel boards need DDR5. DDR4 and DDR5 are not interchangeable, so confirm the platform.
On AM4, DDR4-3600 CL16-18 is the sweet spot for Ryzen. Older Intel boards often favour DDR4-3200. Check your board's supported speeds and buy a matched dual-channel kit.
Yes. Enable XMP (Intel) or DOCP (AMD) in BIOS so the DDR4 runs at its rated speed instead of a slow default. Skipping this leaves performance on the table.
Before ordering a DDR4 kit, confirm your board is DDR4 (not DDR5), check supported speeds, and buy a matched dual-channel pair. Then enable XMP/DOCP in BIOS so it runs at full rated speed.
