Gigabyte Z890 AORUS Tachyon Ice — Extreme Memory OC, White E-ATX

LGA 1851 · Intel Z8902× DDR5 up to 9500+ MT/s OCDual PCIe 5.0 + 4× M.2Wi-Fi 7 · Thunderbolt 4 · 5GbE

The Gigabyte Z890 AORUS Tachyon Ice is an E-ATX motherboard purpose-built for extreme memory overclocking, based on the Intel Z890 chipset and the LGA 1851 socket for Intel Core Ultra Series 2 (Arrow Lake) processors. Sold under Gigabyte part number Z890 A TACHYON ICE (EAN 4719331870898), it features a striking white PCB and heatsinks, a two-DIMM layout with 90°-rotated core slots and an 18+1+2 phase VRM tuned for record DDR5 speeds, plus dual PCIe 5.0 x16 slots, four M.2 slots, Wi-Fi 7, Thunderbolt 4 and 5GbE LAN. Typically in stock with fast delivery across Cyprus.

Compatibility — read before buying
This is an LGA 1851 board supporting only Intel Core Ultra Series 2 (Arrow Lake) processors — not LGA 1700 (12th/13th/14th Gen). It uses DDR5 memory only (no DDR4) and has a two-DIMM layout (max 128GB) optimized for maximum memory frequency rather than capacity. Its E-ATX footprint requires an Extended-ATX-capable case.

Key Features

 
Built for record memory OC
A two-DIMM layout with 90°-rotated core slots, optimized memory traces and the D5 Bionic Corsa design push DDR5 to extreme frequencies (9500+ MT/s, with records beyond 12,000 MT/s).
 
18+1+2 phase extreme VRM
An 18-phase 110A SPS for VCORE plus dedicated VCCGT and VCCSA phases delivers the clean, stable power that extreme overclocking demands.
 
Onboard overclocking kit
An exclusive onboard OC kit with hardware controls, plus AORUS AI SNATCH auto-overclocking and AI Perfdrive BIOS presets, make pushing limits easier.
 
Flagship connectivity
Dual PCIe 5.0 x16, four M.2 slots (one PCIe 5.0), Wi-Fi 7, Thunderbolt 4 and 5GbE LAN cover the fastest graphics, storage and networking.

Frequently Asked Questions

Which CPUs work with the Z890 AORUS Tachyon Ice?
It supports Intel Core Ultra Series 2 (Arrow Lake) processors on the LGA 1851 socket with full overclocking via the Z890 chipset. Older LGA 1700 chips are not compatible.
Why does it only have two DIMM slots?
The two-DIMM layout is deliberate — it shortens and optimizes memory traces for the highest possible DDR5 frequencies, which is the board’s core purpose. It supports up to 128GB.
Who is this board for?
It is aimed at extreme and competitive memory overclockers (including LN2) and enthusiasts who want record DDR5 speeds, rather than general everyday users.
What networking does it include?
Wi-Fi 7 with Bluetooth, 5GbE wired LAN and Thunderbolt 4 over USB-C — fast wireless, wired and external connectivity.
Singular Expert Insight
The Z890 AORUS Tachyon Ice is a specialist board — its two-DIMM, 90°-rotated layout and extreme VRM are built to chase DDR5 frequency records (it set a 12,752 MT/s world record), so it rewards overclockers more than mainstream builders. If you want a flagship Z890 with four DIMM slots and maximum capacity, the Gigabyte Z890 AORUS Xtreme AI TOP or ASUS ROG Maximus Z890 are better all-rounders. Pair it with fast PCIe Gen5 internal SSDs across its M.2 slots.

Buyer's Guide

Buy it if
You are an extreme or competitive memory overclocker chasing the highest DDR5 frequencies, and want a white E-ATX showcase board.
Skip it if
You need four DIMM slots, maximum memory capacity, or just a mainstream build — choose a four-DIMM Z890 or a B860 board.
Also consider
The Gigabyte Z890 AORUS Xtreme AI TOP or ASUS ROG Maximus Z890 for a four-DIMM flagship all-rounder.
