Timetec RAM and IMAC crashing experience - Fixed with new Timetec memory

Update - 07/22/2020Timetec did respond via email to my email request for support. They offered to replace the RAM memory free of charge. It was 9 months old. They provided a free shipping label, and I shipped the product back. They shipped back replacement memory free of charge timely. They sent tracking information. I installed the new Timetec 2 - 16GB cards memory easily and did not need to switch slots as with the prior RAM memory shipped. My iMac recognized the new RAM memory with no problems. I now have 40 GB RAM memory installed, and system is working without crashes so far after 24 hours. I still think it is important for people to know that if your computer system crashes frequently after an upgrade to the RAM, check the RAM. I will update again if I notice my system crashing again in days to months.I am impressed with Timetec customer service. They emailed me that they are a small business, and do not list a phone number or answer a phone. They did everything correct to make this purchase right. I will purchase from them again without hesitation. I am posting to let people know my experience. I upgraded my overall rating to 5 star. I am not going to fault them for the initial bad memory since I realize this can happen with any product. Thank you Timetec :)======================Initial Review - 7/2020I received 2 sticks of 16GB RAM Timetec memory last year and was able to get 27 inch IMAC 2017 5 K display 3.8 Hz working after adjusting which slots to insert memory. I had to move the memory sticks along with the Apple installed memory and it seemed to work when placed in slots 2 and 3. My system had 40 GB of memory. But then my IMAC started crashing. I can't remember how long it took before the system started crashing. It may have been days to weeks. Black screens and reboots. Very irritating. I blamed the Apple product IMAC. I did not associate this with the Timetec RAM memory. We just used our windows computers and other laptops for important stuff in case the IMAC crashed. We have been dealing with the IMAC crashes daily for months. I bought cleanmymac program and this software program also crashed every time it tried to run the RAM check. I contacted cleanmymac and they could not figure it out. We had no viruses or malware. Finally, after additional months of having the IMAC crash, I was ready to junk my IMAC. I had contacted Apple suppliers regarding replacing boards and doing hardware servicing and they all recommended that it would be too expensive. As a last resort, I decided to finally remove the Timetec RAM and guess what?! The IMAC system works without crashing. I tried calling Timetec to discuss, but they don't have a phone number. I am awaiting their response via tech support and support email. I agree with the others here who have had problems with the 2017 IMAC system and can't believe how much time I wasted trying to fix my IMAC issue. I wish I had thought of removing this RAM many months ago. I decided to post this to help others just in case your Apple IMAC starts crashing or giving you problems. Think about removing the Timetec RAM and see what happens. It may save you from junking your IMAC computer. It did for me.

New life to my iMac

Bought this to upgrade my iMac 4k 2017, still had the stock 8gb and despite the change to SSD it was still very slow when opening multiple apps or tabs. With the help of the youtube videos "Upgrade RAM in a mid-2017 21-inch iMac without complete disassembly." and "How to Upgrade/Install Memory in a 21.5-inch iMac (Mid 2017) iMac18,1 iMac18,2" I carefully opened up my machine and within an hour the process was done. Amazing decision and the change is noticeable, the computer recognized the memory right away and has been working properly for a week. Recommended.

PERFECT for 2017 Apple iMac 5K!!!

My new iMac went from 8GB up to 40GB by adding these two 16GB Timetec Hynix memory cards! (For reference, the iMac it replaced maxed out at just 6GB!)I chose the Hynix memory because earlier Apple Macs used this brand. They've been around for a while, which is reassuring. Even so, before buying I emailed TimeTec's support to make sure about their lifetime warranty - and they replied the same day!Their reply: "Please don't worry about it. We provide lifetime warranty for our memory products for US customers. So we can offer you free exchange for replacement anytime you have problems with our memory, no matter how many years you have used it."That level of service and reassurance sold me - as did the competitive price.The installation was easy and took about 5 minutes from shut down to start-up (with everything unplugged in between). The iMac booted just fine on the first try and, as noted in this pic with this review, the 40GB shows up, ready to go! In time, I'll pull the two original 4GB sticks and replace those with another set of TimeTec 2x16GB cards.

Cheap RAM. Works well.

This was the cheapest 16GB DDR4 RAM I could find for a new Intel NUC desktop mini computer. I generally buy RAM first by spec, then by cost. Even if cheap RAM doesn't work, it won't ruin anything. The description of this Hynix RAM says it's for Apple, but it will work in any PC requiring DDR4 laptop memory. I used it in a new Intel NUC with an i7 processor.This is perfectly good RAM. Don't be deterred by description saying it's for Apple. I encountered memoryerrors with the first set of Hynix modules I received, but they were easily returned and replaced. The replacement set works perfectly--and I have the guilty suspicion that the issue with the original set was due to my not seating one of the modules correctly. The second time around the top RAM module went in the slot more cleanly, a difference I only noticed when I was replacing the first set with the second. Sorry, Hynix, it may have been the fault of a balky clip rather than your RAM. I really don't know.This is good RAM at a good price.

The definitive RAM for Retina 5K iMac 27inch mid 2017 model (i7 4.2GHz)

This is my first time buy from Timetec brand. Despite some bad reviews, I trusted and bought it.It turns out to be good value for money.The RAM was easy to install (just follow Apple guide). I put these RAM into existing RAM slots and put existing RAM in remaining two slots. This way I had 40GB RAM.My model is Retina 5K iMac 27inch mid 2017 model (i7 4.2GHz).Then I plugged my iMAC back and hit the power button. After a black screen of 5 or 8 seconds, it boots up and quickly let me to login and voila, I am flying. So far, no issues. 40GB and it is enough for all my needs.I wish the packaging could be more robust (the existing packaging is prone to breakdown if not handled carefully in shipping).

Timetec's reliability and compatibility with specific iMac models make this RAM kit a worthwhile investment for users seeking a boost in their Mac's capabilities.
