Windows 10 crash frequently after upgrade to this 8GB RAM11/5/2020 6:45:16 AM
Overall Review: - Windows 10 crashes frequently despite product is shown as compatible with my DELL Inspiron 3268 Desktop. - Replaced with the original DELL provided 4GB RAM and it worked fine.
Manufacturer Response:
Thank you for purchasing Crucial memory and for your review. We do not show part number CT8G4DFS8266 as being compatible with your Dell Inspiron 3268 desktop. You will want to return this memory and purchase a part number that is compatible with your PC like part number CT8G4DFS824A. We ask that you reach out to us direct if you happen to have any further questions or concerns so that we can assist you further.

Not good5/23/2020 9:23:40 PM
Cons: Ordered the 16 GB kit (2 x 8 GB). At first, my PC indicated the full amount of RAM was installed, but only half of it was usable. Did some trouble shooting, and found that with one of the sticks installed, the computer booted. With the other, it would not, no matter which RAM slot it was in. Returned the kit and received a replacement no problem. The new kit is DOA. Neither stick registers. Very disappointing!
Overall Review: I have no trust in Crucial memory now. Maybe it's bad luck, but...maybe not.
Manufacturer Response:
Thank you for purchasing Crucial memory and for your review. I am sorry to hear about the issues that you experienced with your new RAM. Having multiple bad sticks of memory like this would be extremely rare to see. Crucial memory has extremely low fail rates so we are surprised to see that this happened to you. I am not able to see who the seller of the parts were but we would highly recommend that you reach out to us directly so that we can assist you further. We provide free technical support with our products and would love the opportunity to assist you further.

Cons: None
Overall Review: This field required, NewEgg says. OK- Crucial has never failed me yet. Happy now, NewEgg? :-)

Crucial claims it is not their ram8/11/2022 7:56:32 AM
Pros: Ram worked for a while and then my computer would randomly crash and restart. Tested both sticks (one at a time) with memtest and one of the sticks failed the test due to "too many errors found". Newegg was awesome in resolving the issue.
Cons: One of the sticks failed after 1.5 years (not gaming, just regular office stuff use) and after contacting Crucial and mailing them the bad stick, they informed me that it was not their ram.
Overall Review: The ram worked fine while it did. As mentioned above, Newegg resolved the issue without any hesitation. Thank you Newegg for your dedication to customer service and that is why I have been a customer for almost 2 decades now.

Exceellent upgrade.5/12/2022 3:52:15 PM
Pros: Purchased to 16 GB for a total 64 GB maximum. Very happy so far.
Overall Review: Inexpensive for the return.
Don't waste your time on Crucial RAM.11/21/2021 1:39:39 PM
Pros: Newegg support was helpful.
Cons: Product is unreliable.
Overall Review: Only one of the 16G RAM sticks worked. Second stick was defective, was returned and replaced. Replacement caused system to crash after a few minutes. Got a refund for second stick. Now, after 2 months of use, first stick causes system to crash on startup. Glad I saved the RAM my machine came with. No problem with it. If you are considering Crucial RAM, better to just avoid it.
Manufacturer Response:
We thank you for your feedback and we are sorry that you have faced issues with your Crucial RAM. It is very unlikely for RAM to cause System crashes that frequently. If you want us to investigate the issue in details, we request you to contact our technical support team.
If you have any questions, we welcome your reply.
Have a beautiful day & stay safe!
Regards,
SS

Pros: price was reasonable, but nothing amazing considering you can find same price elsewhere.
Cons: there is absolutely no response from the seller when you try to contact them - exactly what you dont want from an online retailer.
Overall Review: After 9 days of no response to emails, ran out of patience as i have to get the PC built so my son can use it for school work - my bad for not realising this was going to take soooo long. ive now ordered the ram from another retailer that can actually guarantee delivery date. If the sticks ever do arrive i will return them to newegg.
