Buyer's guide

Captain 75T vs Squirrel 35T

The two most popular DMA boards in 2026 — but they're aimed at different players. Here's the head-to-head, no marketing fluff.

TL;DR

Captain 75T — bigger FPGA (xc7a100t die), more logic headroom, runs Premium tier comfortably, classic PCIe slot. Best all-rounder.
Squirrel 35T (484-pin) — xc7a50t die, classic PCIe slot, smaller and cheaper. Fine for Standard/Advanced/Ultimate; Premium fits but tighter.
Squirrel 35T M.2 — same xc7a50t die in an M.2 form factor. Discreet, laptop-friendly. Best for SFF and laptop builds.

Captain 75T in detail

The Captain 75T uses the xc7a100t die (despite the "75T" name — historical naming). The extra logic cells and BRAM mean Premium tier features fit comfortably with margin to spare for future tier work.

Pros: roomy, well-supported, great clean-build performance (no DMA lag, verified on 2 PCs), and the classic PCIe form factor means it's easy to hide in any desktop build.

Cons: slightly more expensive than the 35T family, and the larger PCB is harder to discreetly fit in tight cases.

Squirrel 35T (both variants)

Both Squirrel 35T variants use the xc7a50t die. The 484-pin version is a classic PCIe slot card; the M.2 version uses an M.2 2280 form factor.

Pros: cheaper, smaller, and the M.2 variant is the most discreet DMA you can buy. Squirrel 35T M.2 is the go-to for laptops and SFF.

Cons: less logic headroom — Premium tier fits but with less margin. For COD/RICOCHET-grade play, the Captain 75T's headroom is reassuring.

Gen2 caveat: the 35T family is locked to LINK_CAP_MAX_LINK_SPEED = Gen1. Gen2 breaks the BRAM. The Captain 75T runs Gen2 cleanly. For most game-loop use this doesn't matter — it only matters at extreme bandwidth.

Decision matrix

Your situation	Recommended board
Desktop, plays COD/Warzone	Captain 75T
Desktop, plays PUBG / Tarkov / Fortnite	Captain 75T or Squirrel 35T (484)
Laptop or small-form-factor build	Squirrel 35T M.2
Tightest budget, mainly BattlEye games	Squirrel 35T (484-pin)
Want maximum future-proofing	Captain 75T or Captain 100T

FAQ

Why does the Captain 75T use a "100T" die if it's called 75T?

Historical naming — the 75T name predates the move to xc7a100t silicon. The 35T-family naming is similarly disconnected from the actual xc7a50t die.

Can I run Premium tier firmware on a Squirrel 35T?

Yes — it fits, but with less headroom. For RICOCHET-protected games (COD), the Captain 75T's extra logic is reassuring. For BattlEye/EAC games, the 35T is fine.

Does GhostIO support the Enigma X1?

Yes — Enigma X1 uses the same xc7a100t die as the Captain 75T but with a different pinout. Identical capability.
