4GB Kit (2GBX2) DDR2 667 sodimm RAM, Kuesuny PC2-5300 / PC2-5300S CL5 200-Pin Non-ECC Unbuffered Notebook Laptop Memory Modules

works good

Memory came packaged in plastic clam shell, in non static packaging. Was delivered sooner than estimate. Installation was easy in my HP 6710B notebook. Fired that puppy up, Bios recognized increase memory size, I pressed F1 to accept, and the laptop booted up about 66% faster than it did previously with only 2 gig. No freezing, no paging from hard drive constantly, no Problems at all. Gave new life to a 10 year old laptop, at less than 1/2 the price of others on here. VERY pleased.

Ahhh Matched set of memory for a 2009 computer that needed 8Meg to begin with at the Store . Adding a upgrade from the 2Ghz stock processor with new heat paste and it now plays video with 20 tabs open on 2 browsers plus whatever else bloatware Windows10 has to have stirring around in the background and barely asks Hardrive for any help. The old machine was hitting the ceiling of 4Meg Ram and 2Ghz processor, keeping granpa able to use his 10years to him computer, priceless... now for a video card?

I have a computer that I built back in 2009 that has four RAM slots. Recently the computer started freezing up a lot. I tested the RAM using "Prime 95" and determined that two RAM sticks were bad. I replaced all four sticks with Kuesuny 8GB Kit (2GBX4) DDR2 800 Udimm RAM 1.8V CL6 240 Pin. I then torture-tested the computer again with Prime 95 for 24 hours. The Kuesuny RAM held up to the testing perfectly!Because of the testing I performed, I would highly recommend Kuesuny if you're looking for a great deal, with a great deal of performance!

I have an old dell XPS 420 that I plan on upgrading to it's full potential for office use and maybe even some emulation and light gaming. The 8 gigs popped in and recognized immediately. Warning to those who do not know, if your older ddr2 based system is running on a 32 bit operating system, it will recognize that more than 4gb is installed but say you only actually have 3 to 4 gigabytes of ram. You'll need to upgrade to 64 bit operating system to use 8 gigs of ram in an older system that supports it. It's worth the hassle of upgrading the os believe me. Windows 10 works like a dream on most older hardware and has vastly improved over the last few years. I put 4 star rating for gaming aspect of this product because its possible on an older system like this with a decent enough gpu upgrade and an lga 775 cpu like a core 2 quad q6600 and above. You'll get ok performance and if you dont have the money to build a full on pc it's cheap to put upgrades into these older systems.

Update July 26, 2020:Great company. One of the RAM sticks failed and I emailed them the same day. Due to time zone differences, the company's email volume and possibly language translation/interpretation times, it took a couple of days for Kuesuny to respond to my email. They sent one email a day; so, it took about 4-5 more days of emailing back and forth about trouble shooting and how I came about finding the problem. They are in the process of sending me two replacements.A day or two after my initial email to the company, I had posted this question here, "One of my ram sticks stopped working 1 day after the return period. how can i go about getting this one replaced? (the other 3 work fine for now)". Amazon used to have where the original poster could respond to their own question, but I did not have that option to respond to Evan W. to let them know that I had sent an email already. Don't know if it is my browser or if Amazon changed their software, but I only posted the question since I hadn't heard back. Rest assured, if you have to contact the company, they will respond to your email. It just may take a day or two (depending on circumstances of company).Once I get the replacements, if there are problems, I'll update. Other than that, great product with a customer service that cares.Original post:I have a G33M03 motherboard that still had original RAM sticks (2 x 1GB DDR2 800 MHz and 2 x 512MB DDR2 800 MHz) that performed just fine for most things I did; however, when using just 3 nodes in a docker swarm cluster, the performance went way, way down. After installing the 4 2GB sticks, I'm able to run the same 3-node cluster with ease.I was fortunate to find a post on installing this RAM to this motherboard that described the issues I had with a beeping and no BIOS when initially just installed all 8GBs at once. I followed their instructions by leaving one stick in the DIMM2 slot and turned on, the system made it to booting but no further; so, I powered down, unplugged, held power button for ~5 seconds. I then added one more stick to the DIMM4 slot and turned on with the system fully booting. Fully turned off again (unplugging and everything else), added third stick to DIMM1 slot and it fully booted again and I fully turned off again. Added last stick to DIMM3 slot and powered on and checked with "free" command to see all 8GB there. The post I saw just stated they left one 2GB stick but did not specify which DIMM slot to use, I had read another post somewhere that stated to use DIMM2 and DIMM4 before the other 2, but I do not know if it mattered.I use arch linux but I have no doubts that I could install windows 10 if I wanted. It has only been less than one day and I'll update if any issues come along.

Upgraded older pc memory. Works as it should.

I have an old computer that I bought a couple of years ago (a refurb, so it's even older than that!) for one specific purpose...to run my Christmas light show. It runs that software perfectly fine. What started to happen was that recent upgrades to Win 10 REALLY started to slow the machine down. It came with 4G of DDR2 memory, which is the bare minimum to run Win 10. I couldn't find ANY DDR2 memory for local pickup, so I bought this DDR2 8G bundle. These shipped overnight and I received the next next. Installed and everything works much faster now! So, I highly recommend if you need this older style memory. Fast shipping and delivery and works as expected. A rare 5 Star from me!
