Gigastone Game Turbo 64GB DDR5-6400

Fast and flashy, but the price is a punch in the gut. You're paying a premium for white paint and RGB, not for the best performance.

The speed is the real story here. At 6400 MT/s, this kit lands in the 95th percentile for speed in our database, which is genuinely fast. It's the kind of bandwidth that makes a real difference in memory-hungry games and heavy workstation tasks. The 64GB capacity is also a standout, putting it in the 90th percentile. But that CL40 latency is just okay, sitting around the 73rd percentile. It's not bad, but it's not the tight timing you'd hope for at this price point. The RGB is bright and well-implemented, with eight individual LEDs per stick, so it'll look great in a white build.

Stacked against the competition, the Gigastone has a tough fight. The Corsair VENGEANCE RGB CMH64GX5M2Y6400C32 runs at the same 6400 MT/s but with a much tighter CL32 latency, and it's a more established brand. The G.Skill Trident Z5 Royal is another strong contender with better timings and a premium build. The Kingston FURY Beast is a solid budget alternative if you don't need the RGB. Honestly, the Gigastone's main selling point is the white color scheme, because on pure specs, the Corsair and G.Skill kits beat it where it counts.

This is where things get rough. At $999 USD, this kit is in the 9th percentile for affordability, which means it's one of the most expensive options out there. You're paying a premium for the white aesthetic and the RGB, but the performance doesn't fully justify the cost. You can find faster kits with tighter timings for less money. Unless you absolutely need this exact look, the value just isn't there.

The Gigastone Game Turbo RGB is a 64GB DDR5 kit that screams for attention, both with its white heat spreaders and eight RGB LEDs per stick. The headline here is capacity and speed, you're getting a massive 64GB running at 6400 MT/s, which puts it in the top tier of what we've tested. But that CL40 latency is a bit of a buzzkill, and the price tag is going to make most people do a double take.

If you're looking for the best raw performance per dollar, this isn't it. Go grab the Corsair VENGEANCE RGB with CL32 timings instead, you'll get better latency for less money. And if you're building a server or workstation that needs ECC memory, this kit is completely wrong for you, it's non-ECC and our server score for it was a dismal 35.4 out of 100.

The Gigastone Game Turbo RGB is a fast, high-capacity kit that looks fantastic in a white build. But the CL40 latency and the eye-watering price make it hard to recommend over the competition. If you're building a showpiece PC and money is no object, it'll do the job. For everyone else, there are better options that cost less and perform better.
