64GB suits heavy video editing, large datasets and virtual machines. Every pick is a 64GB kit, ordered from the lowest price.

We sorted these picks by CAS latency, rated speed and capacity, working from the makers' own data; if a maker skips voltage, the guide says so, and no figure here comes from our own testing.

Our Picks

Tightest CAS Latency1 of 5

CORSAIR Vengeance LPX 64GB (2x32GB) DDR4-3200 CL16

Vengeance LPX 64GB lists DDR4-3200 at CL16 across two 32GB sticks.

Best for

Buyers who put CAS latency first.

Skip if

Skip it if rated speed matters most to you; the Delta RGB 64GB offers 6400MT/s.
CORSAIR Vengeance LPX 64GB (2x32GB) DDR4-3200 CL16

Why we like it

On CAS latency it leads this guide at CL16, ahead of the Flare X5 64GB (CL30). On rated speed it trails the group at 3200MT/s, while the Delta RGB 64GB offers 6400MT/s. It is the only pick here with a DDR4 memory type; the Flare X5 64GB has a DDR5 memory type instead.

It also comes with timings of 16-20-20-38 and a low-profile heatspreader. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR4 kit, so it fits AM4 boards and LGA1700 boards sold in DDR4 versions; it does not fit AM5, LGA1851 or any DDR5 board. It was the cheapest of the group when we checked; the Flare X5 64GB was the next step up.

The catch

If rated speed is your priority, the Delta RGB 64GB (6400MT/s) is the stronger choice.

Also Consider2 of 5

G.SKILL Flare X5 64GB (2x32GB) DDR5-6000 CL30

The Flare X5 64GB kit brings 64GB at 6000 CL30 with EXPO.

Best for

Buyers who want timings of 30-40-40-96.

Skip if

Price-first buyers should look at the Vengeance LPX 64GB, which cost less when we checked.
G.SKILL Flare X5 64GB (2x32GB) DDR5-6000 CL30

Why we like it

It suits a 9800X3D machine that also edits video. On CAS latency it ties with the Delta RGB 64GB and the Trident Z5 Neo 64GB at CL30. Like the Trident Z5 Neo 64GB and FURY Beast 64GB, it has EXPO profiles, while the Delta RGB 64GB uses XMP profiles.

It also offers timings of 30-40-40-96. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots. On price it sat second of 5, between the cheaper Vengeance LPX 64GB and the pricier Delta RGB 64GB, at the time of writing.

XMP Profiles3 of 5

TEAMGROUP T-Force Delta RGB 64GB (2x32GB) DDR5-6400 CL30

Delta RGB 64GB offers 6400MT/s at CL30 with XMP, the tightest timings among the 64GB kits here.

Best for

Buyers who want XMP profiles.

Skip if

Choose another pick if you can't accept this: xMP profile only, so AM5 boards may need manual timings.
TEAMGROUP T-Force Delta RGB 64GB (2x32GB) DDR5-6400 CL30

Why we like it

It matches the Flare X5 64GB and the Trident Z5 Neo 64GB on CAS latency (CL30). It matches the FURY Beast 64GB on rated speed (6400MT/s). XMP profiles is unique to it among these picks, while the Flare X5 64GB uses EXPO profiles.

You also get Micron M-die memory. Enable the memory profile in the BIOS after installing it; without it, the kit runs at a slower default speed. It is a DDR5 kit for AM5, LGA1851 and DDR5 versions of LGA1700 boards; it does not fit DDR4 slots.

RGB heatspreaders are taller than plain ones, so check the clearance under a large tower cooler. It was priced above the Flare X5 64GB and below the Trident Z5 Neo 64GB at the time of writing.

The Vengeance LPX 64GB sat in the $500 to $1000 tier and the FURY Beast 64GB in the $1000 to $1500 tier when we checked, with 3 other picks between them; pay the difference only if rated speed decides your purchase.

What makes the Vengeance LPX 64GB the Tightest CAS Latency?

The label rests on the tightest CAS latency here (CL16). The Flare X5 64GB is next on CAS latency at CL30, so this pick's CL16 is 47% further out. It is aimed at anyone who puts CAS latency first.

Do the Vengeance LPX 64GB and the Flare X5 64GB differ on voltage?

The Vengeance LPX 64GB uses 1.35V; the Flare X5 64GB and the Trident Z5 Neo 64GB use 1.4V. The makers of the Delta RGB 64GB and the FURY Beast 64GB don't state voltage, so 3 of 5 picks are covered here.
