DMA compatibility scan before you buy
IOMMU, VT-d, PCIe slot placement and motherboard checks for Cloud DMA hardware on Warzone PC.
Cloud DMA only works when your gaming PC motherboard, BIOS, and PCIe layout cooperate with your DMA card. Buying hardware before running a compatibility scan is the most common expensive mistake new operators make. This guide covers what the portal scan checks and how to fix failures.
IOMMU and VT-d
Intel VT-d and AMD IOMMU must be enabled in BIOS for clean memory group isolation. Some boards ship with it off by default; others break DMA reads when enabled on specific slots. The compatibility scan reports your current IOMMU group layout and flags known bad combinations for popular chipsets.
PCIe slot placement
Not every x16 or x4 slot routes through the CPU directly. Some lanes go through the chipset and add latency or block DMA reads entirely. Use the slot recommended for your motherboard family—Discord support maintains a list for common ASUS, MSI, and Gigabyte boards used in Warzone setups.
Card class: 35T, 75T, 100T
Lower-tier cards cost less but may struggle with large Warzone memory maps after major updates. 75T class is the sweet spot for most operators. 100T class suits dual-PC setups running heavy overlay dashboards alongside read threads. Match card tier to your operator PC specs, not just the gaming rig.
Common scan failures
Virtualization software, old VPN drivers, and leftover anti-cheat kernel hooks often fail scans before hardware is even at fault. Clean boot the gaming PC, disable Hyper-V if unused, and rerun. If the scan still fails, post your motherboard model and BIOS version in Discord before RMAing a working card.
Pre-purchase workflow
Open a Discord ticket with your motherboard, CPU, and intended PCIe slot. Staff confirm support status before you checkout Cloud DMA at warzonecheat.net/products/warzone-cheats. Ten minutes of verification beats a week of returns.
