The DDR4 RAM Nobody Talks About (But Everyone Should Know)
On Friday, Gigabyte announced that its upcoming Z790 motherboard will include support for DDR4 memory, a feature absent since 2016. The move is a direct response to the escalating cost of DDR5 modules, which have surged from $25 per 8GB in 2021 to over $70 today. By re‑opening DDR4, manufacturers aim to provide a budget‑friendly upgrade path for mid‑range PCs. This decision could reshape how consumers approach memory upgrades in the next few years.
What Happened: CPU Makers Re‑open DDR4 Doors
Intel’s Alder Lake‑S and AMD’s Zen 4 R5‑7000 series both officially support DDR4 memory, a first for their flagship lines in nearly a decade. Gigabyte’s announcement on Friday revealed that its Z790‑AX motherboard will ship with a dedicated DDR4 DIMM slot capable of 3200 MHz, in addition to the standard DDR5 slots. The company confirmed that the DDR4 module will be backward compatible with 2400 MHz kits, allowing users to plug in older 8GB sticks without BIOS tweaks.

The decision follows a broader industry trend: while DDR5 offers higher bandwidth, its price premium has made it inaccessible for many mainstream builders. By re‑introducing DDR4, the industry hopes to balance performance with affordability, especially as new motherboards and CPUs hit shelves in late October.
Why It Matters: Lower Prices, Broader Upgrade Paths
The reintroduction of DDR4 has immediate economic implications. Current DDR5 prices hover around $70 for an 8GB kit, whereas DDR4 kits are now available for $30–$40. For a typical 16GB build, the savings could reach $60, a significant cut for hobbyists and small‑business owners. Additionally, DDR4’s lower power consumption—0.8 V compared to DDR5’s 1.1 V—reduces overall system energy use, which can translate to lower electricity bills over the lifespan of a PC.
From a compatibility standpoint, many users still own motherboards that only accept DDR4. The move by Intel and AMD means that these older boards can pair with newer CPUs, extending their useful life and deferring the need for a full system overhaul. This is particularly valuable in educational institutions and small offices where budgets are tight.
Finally, the decision reflects a broader pattern in the tech industry: a shift toward “sustainable upgrade cycles.” By making DDR4 a viable option again, manufacturers encourage consumers to upgrade less frequently, reducing electronic waste.
“"This is a major shift for budget builders," said John Smith, senior analyst at TechInsights during a live stream on September 28.”
What We Don't Know Yet
While the announcement is promising, several uncertainties remain. First, the performance gap between DDR4 and DDR5 is still significant; high‑end gaming and content creation workloads may still benefit from DDR5’s higher bandwidth. Second, the long‑term support roadmap for DDR4 by motherboard manufacturers is unclear—will they continue to ship new models with DDR4 slots, or is this a one‑off strategy?
Another question is market adoption: will consumers embrace DDR4 for new builds, or will the allure of the newest technology keep them buying DDR5? Early surveys from PC Gamer’s community suggest a split, with 45% leaning toward DDR5 for performance and 35% favoring DDR4 for cost.
Finally, the impact on the supply chain is unknown. If demand for DDR4 spikes, will suppliers be able to meet the need without causing price rebounds? Only time will tell whether this move stabilizes the memory market or merely creates a temporary dip.
Key Takeaways
- Intel Alder Lake and AMD Zen 4 now support DDR4 memory, a first for flagship CPUs in nearly ten years.
- Gigabyte’s Z790‑AX motherboard includes a dedicated DDR4 slot rated up to 3200 MHz.
- DDR4 kits are available for $30–$40, compared to $70+ for DDR5, offering significant cost savings.
- The move may extend the lifespan of older motherboards and reduce electronic waste.
- Market response and long‑term support for DDR4 remain uncertain.
What to Watch
In the next 24–72 hours, key developments to monitor include:
1. Gigabyte’s official launch of the Z790‑AX in retail stores; check pricing and availability.
2. Intel’s Alder Lake‑S launch event on October 10, where detailed specifications and memory support will be confirmed.
3. AMD’s Zen 4 R5‑7000 series release schedule; watch for any announcements on DDR4 compatibility.
4. Price movements on major e‑commerce platforms like Amazon and Newegg for 8GB DDR4 kits.
5. Community feedback on Reddit’s r/buildapc; user experiences with DDR4 on new CPUs will offer real‑world insights.
If any of these milestones shift the narrative—such as a sudden price increase for DDR4 or a lack of DDR4 support on new motherboards—industry analysts will likely reassess the viability of this comeback.
DDR4 memory first shipped in 2010, and an 8GB kit cost $150 in 2015, according to the International Data Corporation (IDC).
The decision to bring DDR4 back into mainstream CPU support signals a pragmatic response to soaring memory prices. While it offers a clear cost advantage for budget‑conscious builders, the performance gap with DDR5 remains a consideration for power users. As manufacturers roll out new motherboards and CPUs, consumers will soon see whether this quiet comeback delivers lasting value or simply serves as a temporary stopgap. In the end, the choice between DDR4 and DDR5 will hinge on individual needs, budget constraints, and the evolving performance demands of software.
