Stability and Compatibility over speed
TL;DR got 4 sticks of 8 gb CT2K8G48C40U5 4800mhz. WORKS PERFECT with Asus TUF gaming x670e + Ryzen 7950X previously tried to install 6000mhz gskill 2x 16gb sticks. non stop random blue screens and windows corruption. thought it was RYZEN 9 7950X, was able to rule out. thought it was motherboard asus tuf gaming x670e but was also able to rule out by picking up a 2x stick of this exact ram. once confirmed it was good bought another pair to top out at 32gb. smooth sailing since then and the 4800mhz hasent affected speed by much at all. another lesson that speed dont matter if its at the price of stability. cherry on top? SUPER affordable.

IS IT WORTH IT? (2 Weeks Later)
I wanted to wait two weeks before reviewing the product in case any issues came up, as I found some of the reviews were bare-bones and only wrote it after opening the box / first boot up. I know when ordering hardware you want to know it won't immediately brick after a few boots, so while it's only been a little bit - i have been able to run with this new RAM enough times to be confident in my opinion. THE PRODUCT: The RAM came extremely well packaged with a lot of padding and wrapping to ensure it wasn't damaged during transport. It was next day delivery as well, with Royal Mail (not amazon delivery) with tracking and a lot of protection in place. This helped reassure that they were absolutely taking all measures possible to make sure I, the customer, got the RAM in good condition and fast. When I took it out to inspect it it was in phenomenal standard baring in mind I had selected their "used" option due to my budget. I couldn't find any defects or reasons that someone would have returned it, and honestly if you had told me it was a completely new one I would have believed you. The set up was easy and my PC only took a few minutes to adjust, and let me tell you... YOU CAN FEEL THE DIFFERENCE. It was running extremely smoothly, there were no hiccups or errors to boot. It really was as simple as put the new RAM in -> wait for it to adjust -> boot up PC. Some guides online do recommend changing specific bios settings when adding new RAM, but mine worked perfectly fine without changing any settings. After two weeks it's still running smoothly and extremely optimal, I haven't encountered any issues yet (if I do I will update this review). Overall it is an amazing product and a good way to get RAM during the current RAM increase. COMPANY: The company, since the beginning, has been extremely helpful and patient. My expertise is in software, so when trying to mod my new computer with new hardware I didn't know where to start. Originally, I had ordered the wrong RAM as it was for a latop, and they cancelled the order so that I could get a refund. They also reached out on amazon messages asking for my hardware details so they could ensure I got the correct RAM, and when I hadn't responded (as I didn't know amazon messages existed) they called me and were extremely patient in explaining the steps i needed to take and what information they required. THEN! When they only had one 32 gb stick left in the speed I had ordered ( I had ordered two sticks for context) they contacted me to inform me of this. I was expecting a delay while they waited to get another stick in, BUT INSTEAD they upgraded me to reieve TWO 32 GB DDR5 RAM in a faster speed for no additional cost that was also compatible with my motherboard! They also sent a guide on what to do during set up, so that when it black screens while processing the new memory it doesn't cause panic. Overall the team were extremely helpful, kind and patient while I tried to figure out how to do this and I could not recommend them more. CONCLUSION : I think if you're wanting to upgrade your PC this is definetly the RAM to buy. It's a good price, it's durable, it ships quickly and safely, it is extremely stable and most importantly : it has a phenomenal team backing it.

DRAM Prices pain
Works fine - just not great for the price at the moment. No heatsink - sort of ugly. Also only 4800 mhz, which may be a significant detriment if not used on an x3d chip.

good temporary ram
arrived amazingly quick, its a good cheap piece of ram that will do until you can afford 16gb or 32gb, was a bit hard to slot into the motherboard dimm slot but it made it in eventually. they are low-profile too which is a positive especially since im using a massive cpu cooler that overhangs them.

Chose wisely - perfect upgrade!
Fantastic, did just the job I needed. Upgraded to 32gb up from 16gb and bought 2 of these 8GB to fit my purpose. Certainly a noticable difference in speed and latency! Fit my system perfectly, I'm not that techy when it comes to RAM and finding the right one, so I'll admit I used Chat GPT to confirm the right RAM. Installation was flawless, just make sure if you get one to unplug your PC and hold the power button to ensure no remaining electric in your PC for safe installation. This RAm certainly is great for stability, if you're looking for faster load times and lower latency with increased FPS, then upgrading is the right way to go.

it works
kinda hard to install due to the fact it is so slim that the ram is not easy to install and instead causes extreme pain on your fingers

Crucial RAM DDR5 32Go 4800MHz, PC Mémoire
Parfait, aucune mauvaise surprise et reconnu sans problème par ma carte mère. Je recommande donc. Avant de l'acheter, ne pas hésiter à aller sur le site constructeur de votre carte mère pour s'assurer de la compatibilité.

Added Crucial 2x 8gb DDR5-4800 to a Dell XPS 8950 (i5-12400) that had an existing 2x 8gb SK Hynix DDR5-4800. Happy to report all 4x of the 8gb ram ran at the max of 4800. Added them to the 2 empty slots and had no issues at boot up.
