Crucial Pro DDR5 RAM 64GB Kit (2x32GB) 6400MHz CL40, Overclocking Desktop Gaming Memory, Intel XMP 3.0 & AMD Expo Compatible – White CP2K32G64C40U5W

I've been using G.Skill memory for many years and been satisfied. I decided to get this Crucial memory just when memory prices began to soar. This one was significantly more cost effective then my typical choices at the time. I was pleased to find this works better with the motherboard I'm using in my primary system. With my previous memory, I would sometimes need to manually lower the speed slightly to maintain stability. This memory has not had the same issue. I just turn on EXPO (XMP) and it works. It has been flawless so far. I usually run 64GB in my system. I use it for both work and play. It is uncommon for me to use more than 32GB but when I do need it, there is no substitute. I chose the white sticks simply because the pricing was in flux and the white ones were a lot cheaper than the black ones at the time. Technically, black is better as it is capable of radiating more heat. However, I don't think it makes very much difference in this case. It is sad that I discovered how much I like Crucial memory at the same time they announced they will be exiting the consumer memory market in order to focus on supplying AI datacenters.

works great

I ordered this RAM with the hopes that I would be able to utilized the XMP ability of the Alienware ACT1250. I ordered the system with 16GB of 5200 MT/s with the expectation of immediately swapping it out for a 64GB kit of this 6400 MT/s. Before I even turned on the system for the first time, I swapped out the RAM. I had no issues with the system booting up. I read some people had issues with the ACT1250 booting up to a 4k monitor. I only have a 1440p, so just something to be aware of if you have a higher res monitor. I felt like the look of this ram fits in better with my system with the included black heatsink. The Dell/Alienware is ridiculously picky with it's ability to enable XMP. Supposedly only a Kingston RAM kit that no one can seem to find anywhere online is the only one on their "Dell certified" XMP list. The Dell/Alienware motherboard won't allow XMP to be enabled. This memory runs at 5600MT/s out of the box for my ACT1250. CPU-Z does recognize that it has the ability of the XMP-6400 and XMP-6000 frequency. RAM has been running fine with no errors detected with MemTest86. I've been playing Killing Floor 3 paired with a RTX 5080 and Intel Core Ultra 7 265KF and had no issues at all. I wish I could get the memory running at the speed it was designed for, but that's a ridiculous compatibility mechanism implemented by Dell/Alienware, not Crucial. Screenshots included.

Stable, fast, and looks sleek. 64GB is plenty for heavy multitasking and gaming. No issues hitting the advertised speeds with Expo enabled

I grabbed the Crucial Pro DDR5 64GB Kit (2x32GB) 6400MHz CL40 for my rig and it’s been excellent—fast, stable, and easy to set up right out of the box. Performance has been smooth across gaming and heavy multitasking, and the sleek low-profile design fits perfectly without clearance issues. Compared to my previous Corsair kit, this Crucial Pro feels more reliable and consistent, giving me better overall value and peace of mind for long-term use.

UPDATE: 5 months after purchasing one stick has completely failed. Only gets recognized as 4gb regardless of what slot it’s installed into. EXTREMELY upset as prices are through the roof now. Unreal. Crap quality, so glad they’re not producing any more consumer products; maybe now that they’re going commercial-only people can start being held accountable for garbage quality. Zero stars if I could. Works great, even though it's CL40 I have great performance with EXPO on. Sorry to anyone who didn't grab this before the price skyrocketed. What a shame.

2x32 6400MHz @200$. 4 stars, CL40 is not the best (it is good). Was worth the cost at the time of purchase, not now (pushing five hundred).

Excelente, me ayudaron en la velocidad de procesos de mi pc, lamento no haber comprado otro par en su momento, llegaron en buenas condiciones

Work good with the build I did.

Ich habe mir das Crucial Pro DDR5 Kit mit 64 GB (2×32 GB) für meinen neuen Gaming- und Arbeits-PC gegönnt und bin absolut zufrieden. Mit 6400 MHz Taktfrequenz und CL40 liefert der RAM eine tolle Performance, sei es beim Gaming, beim Arbeiten mit großen Dateien oder beim Multitasking. Dank XMP 3.0 und EXPO lief das Kit auf Anhieb stabil – sowohl mit Intel als auch mit AMD Boards. Pro: • 64 GB Kapazität – reichlich Reserven für Gaming, Streaming und Content Creation • 6400 MHz DDR5 – spürbar schneller als Standard-RAM • XMP 3.0 / EXPO Unterstützung – unkompliziertes Overclocking auf Knopfdruck • Stabile Performance: Läuft absolut zuverlässig, keine Abstürze oder Fehler • Schickes weißes Design – passt perfekt in helle Builds und zu RGB-Setups • Gutes Preis-Leistungs-Verhältnis für High-Speed-DDR5 Contra: • CL40 ist nicht die niedrigste Latenz – Enthusiasten könnten auf noch schärfere Timings setzen • Heatspreader ist eher schlicht – kein RGB, was manchen fehlen könnte • 64 GB sind aktuell für Gaming fast überdimensioniert (aber zukunftssicher) Fazit: Das Crucial Pro DDR5 Kit ist eine hervorragende Wahl für alle, die viel RAM brauchen und Wert auf Geschwindigkeit und Stabilität legen. Gerade für High-End-Systeme, kreative Anwendungen und Gamer mit Blick in die Zukunft ist dieses Kit absolut empfehlenswert. Wer es schlicht, schnell und zuverlässig mag, wird hier sehr glücklich.

Excellent product, looks great and no faults after 3 months of use. The price though has more than tripled since I purchased it in September 2025. It is because Americans are printing money and exporting inflation to fund their AI projects (over half a trillion and counting), which could make this product even more unaffordable if AI takes your job.

普通に満足してます

Had some compatibility issues on an ASUS Strix X870e-e board. Could mever get it to train to full 6400 speed. Works well on an MSI MPG X870E Carbon.
