Corsair Dominator Platinum RGB 32GB DDR5-6600 CL32

Ranked #10 in RAM

334 LP on the category ladder what's LP?

One of the fastest DDR5 kits reviewers had tested when it launched, but it carries only an Intel XMP profile, needs a motherboard that can run DDR5-6600, and showed no overclocking headroom at all in Tom's Hardware's test.

About this product

This page covers the Corsair Dominator Platinum RGB CMT32GX5M2X6600C32 in black, a 32GB DDR5 desktop memory kit made of two 16GB sticks with 12 Capellix RGB LEDs on each module. It boots at 4800MHz and reaches its rated 6600 MT/s at 32-39-39-76 and 1.40V once you turn on its single Intel XMP profile in the BIOS.

Corsair optimizes this kit for Intel and lists compatibility with Intel 600, 700 and 800 series motherboards only. It suits an enthusiast Intel build with a board that can handle DDR5-6600, and a case with room for 56mm tall modules.

Tom's Hardware and TechPowerUp both tested this exact part number in 2022 on Intel Core i9-12900K systems. They agree on its speed and build quality but disagree on how far it overclocks.

Pros & cons

✓ Took first place in Tom's Hardware's application performance chart and was the first DDR5 kit in its lab to break 140,000 points in 7-Zip compression
✓ Tight 32-39-39-76 timings from hand-sorted memory chips
✓ The only kit TechPowerUp had tested that passed its 1.5V stress test with no airflow, helped by thermal pads under the heat spreader
✓ Solid construction and great PCB build quality, according to both reviewers
✓ Limited lifetime warranty

✗ Only one profile, Intel XMP, and Corsair lists no AMD motherboard compatibility
✗ Not plug and play on every board: TechPowerUp's ASUS Z690 Hero needed voltage changes before DDR5-6600 was stable
✗ No overclocking headroom in Tom's Hardware's test, even at 1.5V
✗ At 56mm the modules stand tall, which matters under very large CPU coolers
✗ At review time, TechPowerUp's kit did not show up in iCUE until SPD Write was enabled in the BIOS

However, Corsair's memory kit is the best option if you value performance above everything else.

Strictly speaking in terms of Intel Z690 (LGA 1700 platform) support, chances are this memory will not be plug and play for a lot of motherboards.

Frequently asked questions

It ranks #10 of 15 on our RAM tier list, in D tier. That placement draws on 2 independent outlets.

Corsair does not list it for AMD. The kit carries a single Intel XMP profile and Corsair's compatibility list names only Intel 600, 700 and 800 series motherboards. Both reviews tested it on Intel systems only.

Not on every board. TechPowerUp found its ASUS Z690 Hero needed voltage adjustments before the XMP profile was stable, while a Gigabyte Z690 Aorus Tachyon ran it with ease. TechPowerUp advises updating the BIOS first and checking that your motherboard supports DDR5-6600.

Corsair lists Dominator Platinum RGB DDR5 modules at 56mm (2.2in) tall. Tom's Hardware says that should only be a problem with an extremely large CPU cooler, so compare 56mm with the memory clearance your cooler's maker lists.

Results differ. Tom's Hardware could not get its sample stable above DDR5-6600 or tighten its timings, even at 1.5V. TechPowerUp reached 6800 MT/s at 1.45V and DDR5-6933 with more voltage on an overclocking board, but found light overclocking not worth it next to the XMP profile.

It is designed to. Corsair builds the lighting around its iCUE software, but TechPowerUp's kit did not appear in iCUE at the time of its review until the SPD Write option was enabled in the motherboard BIOS.
