Targeted compatibility

This 16GB kit is built specifically for Gigabyte Z370 AORUS Ultra Gaming 2.0 series motherboards including the Ultra Gaming 2.0-OP, Ultra Gaming, Ultra Gaming WiFi and Ultra Gaming WiFi-OP models. Two 8GB DDR4 modules run at 2400MHz with CL17 timing at 1.2V. The unbuffered non-ECC design matches the board's four DIMM slots and 64GB maximum capacity.

Sustained workload behaviour

The DDR4 2400 speed and 17-17-17 timings deliver consistent bandwidth during extended sessions rather than brief bursts. Dual-rank 2Rx8 organisation helps maintain throughput when all four slots are populated. Operating at the standard 1.2V keeps thermal output predictable inside a closed case over long periods.

Build and daily implications

Modules ship without heat spreaders, so they fit under oversized CPU coolers without clearance checks. The 288-pin DIMM form factor seats firmly in the board's slots with a single click per stick. A limited lifetime warranty from Computer Memory Solutions covers manufacturing defects for the original purchaser.

Questions about this item

Does the 1.2V DDR4 kit run hot or draw much power during all-day use?

The modules operate at 1.2V with no heat spreader, so they stay cool and draw minimal power even under continuous load.

What must the motherboard provide for these two 288-pin DIMMs to work?

A Gigabyte Z370 AORUS Ultra Gaming 2.0 series board with four DDR4 slots supporting up to 64GB total capacity.

Will this 2400MHz CL17 kit slow down if I keep older DDR4 sticks in the other two slots?

All populated slots run at the lowest common speed and latency, so older modules will set the pace for the whole system.
