RTX 4090

Overview

RTX 4090 appears in this dataset mainly in Exxact workstations and towers used for AI, visualization, and compute-heavy Linux or Windows workflows, often as single- or dual-GPU systems. The ticket mix is dominated by no-display or no-POST failures, workload crashes that were later isolated to the GPU, shipping or seating damage in heavy systems, and a smaller set of setup questions around display path, chassis fit, and OS behavior.

Known Issues

• GPU Hardware Failure (~20 tickets) - dead cards, no signal, display corruption, crashes under load, and GPUs that prevent POST when installed. Examples: #10155, #13030, #22227, #34939, #35134.
• System Boot Failure (~14 tickets) - Q-code 97, no video at boot, systems that only POST without the GPU installed, or full-system no-boot cases where the 4090 path was central. Examples: #11212, #11852, #23107, #26217, #32991.
• fan failure (~2 tickets) - fan stoppage or cooler-side failure that caused shutdown or startup instability. Examples: #13107, #35515.
• Shipping Damage (~3 tickets) - heavy 4090 systems arriving with shifted cards, damaged PCIe slots, or freight-packaging concerns. Examples: #26217, #34745, #34977.
• Memory Hardware Failure (~2 tickets) - a few tickets that initially looked like 4090 faults later pointed to RAM or broader platform issues instead. Examples: #31296, #38401.

Common Questions

• Why does the system show no display or Q-code 97 with the RTX 4090 installed? Support usually starts with slot/cable isolation, swap testing, power drain, and checking whether the system boots normally once the GPU is removed. Examples: #11212, #11852, #12261, #26217, #34977.
• How do we tell whether the problem is the 4090 or the motherboard/slot? The strongest evidence comes from moving the card to another slot or system and seeing whether the failure follows the GPU. Examples: #12261, #13030, #32258, #34939, #35134.
• Can an RTX 4090 cause full-system crashes under heavy compute load? Yes. Several tickets ended with the GPU isolated as the root cause after the customer first suspected drivers, OS issues, or the whole system. Examples: #10155, #20034, #24427, #26455, #26860.
• Why would a 4090 system boot to BIOS but not boot the OS? In this set, the cause varied: some tickets pointed to GPU instability, some to firmware or BMC/CMOS state, and some to unrelated memory/platform issues. Examples: #25591, #26318, #30133, #31296.
• What if the card was damaged in shipping or shifts in transit? Exxact often moved these to full-system RMA because the GPU weight could also damage the PCIe slot or board. Examples: #26217, #34745, #34977.
• Will a nonstandard 4090 fit in an older Exxact chassis? Not always. Clearance, fan relocation, PSU headroom, and power-cable routing matter, especially for large aftermarket cards. Examples: #18183, #33493.

Related Products

• RTX 3090 - the most common comparison point for swap-testing, upgrade discussions, and older multi-GPU workstation behavior (#34939, #7181).
• RTX 5090 - appears in replacement-path and compatibility conversations when a failed 4090 was being substituted or compared (#33493).
• Dual-4090 Exxact workstations - many tickets are really about platform behavior in two-GPU towers, not just a single card in isolation (#16872, #23107, #26455).
• Large Zotac / MSI / PNY 4090 variants - exact vendor and cooler form factor matter for fit, shipping risk, and replacement handling (#10155, #22227, #27652, #33512).
