24GB GDDR6X 384-bit graphics card

The ASUS ROG Strix RTX 4090 OC Edition equips 24GB of GDDR6X memory across a 384-bit bus for high-resolution gaming and professional rendering. It targets enthusiasts who need maximum frame rates at 7680x4320 and creators who rely on 16384 CUDA cores for compute workloads. The card plugs into a PCI Express 4.0 slot and draws power through a single 16-pin connector.

Axial-tech fans with 23% more airflow

Enlarged Axial-tech fans move 23% more air than the previous design, keeping thermals in check while the boost clock reaches 2640 MHz in OC mode and 2610 MHz in Gaming mode. A 3.5-slot footprint and a 1000W recommended PSU indicate the power budget behind the 1368 AI TOPS rating. The vapour-chamber cooler and ARGB lighting stay quiet under typical gaming loads.

3.5-slot build with HDMI 2.1 and DisplayPort 1.4

The metal frame measures 357.6 x 149.3 x 70.1 mm and occupies 3.5 slots, so case clearance must be verified before installation. Two native HDMI 2.1a ports and three native DisplayPort 1.4a outputs support up to four displays at 7680x4320 with HDCP 2.3. A bundled ROG graphics card holder and velcro straps help secure the heavy PCB and manage cables day to day.

商品問答

How do I install this 3.5-slot card and what is the step people often miss?

Mount the card in a PCI Express 4.0 slot, connect the single 16-pin power connector, and use the included ROG Graphics Card Holder to support the 357.6 mm length so the PCB does not sag over time.

What maintenance will this 24GB GDDR6X card need later?

Periodically clean dust from the three Axial-tech fans and the large heatsink fins; the 16-pin connector should be reseated if you ever rebuild the system, but no user-serviceable parts require scheduled replacement.

What limit appears first when the 2640 MHz OC boost runs continuously?

The 1000 W PSU recommendation and 3.5-slot thermal envelope mean power and heat ceilings arrive together; sustained loads will hit the boost clock ceiling once the cooler reaches its maximum dissipation capacity.
