I promptly received the product on schedule and installed the memory modules in my Toshiba Satellite laptop. The specs on the new and old memory chips were identical and the laptop booted up with no errors. Windows 7 immediately recognized that I now had 4GB of memory installed instead of 2GB and the boost in system performance was very apparent. I would definitely recommend anyone running Windows 7 or newer to increase their memory to improve system performance and their computing experience. I was a very happy customer for about an hour. I walked away from my PC to watch some television and when I came back my laptop had gone into sleep mode (as it should). I woke up the computer and the logon screen was filled with white horizontal stripes. That's not a good sign. I logged on and was greeted by a loud annoying screech, almost like what an old style modem would make but louder and more annoying. The noise wouldn't stop so I rebooted the laptop. The laptop restarted without any issues and everything appeared normal. I forced my laptop into sleep mode and woke it up again to find the same distorted screen and loud annoying screech. I repeated the steps a could times to ensure I could recreate the issue. Now I know what memory gone bad sounds like. I reinstalled my old memory and the problem hasn't occurred again. I plan to return the memory and possibly buy another set to see if I have better luck. Update: I ordered another set of memory chips of the same type which promptly arrived. My laptop wouldn’t even boot up with the new set. The specifications on the original memory from the laptop matches the specs on the new memory so I know I didn’t order the wrong memory. I went ahead and ordered a different brand of memory to see if I would have better luck. That third set of memory behaved in a similar manner as the first set of A-Tech memory in that if functions properly until the PC comes out of hibernation / sleep state. What I’ve learned from this experience is that not all memory is of the same quality, and each computer can be sensitive to various qualities of memory. I might have better luck if I try some of the more expensive memory that costs 3 - 4 times as much. I have an older laptop that I didn’t want to invest much money in. If I was upgrading an Apple computer I would invest more money for reliable and stable memory. It really depends on how stable you need your computer to be. If you’re on a budget and want a cheap solution that may / may not work with your PC then this product might be a good fit for you. Based on other reviews it appears that many people have had better luck than I. I’m going to leave my rating a one star because the two sets of memory I received provided inconsistent results.

solid ram it worked great. revived an old computer that was trying to run windows 7 with 1 gb of ram and was painfully slow as it kept dipping into the virtual memory which grinds everything to a halt. after the upgrade it can now do everyday task as its no longer ram limited. the 4gb kit was cheaper than the 2gb kit so it was a no brainier. IF you are looking to upgrade an old rig make sure its ram limited and you cpu is not getting pined at 100% use task manager and watch your ram usage if you are hitting ram limits with cpu still at bellow 90% this upgrade is for you. the person i did this for was very happy as they no longer had to buy a new laptop Read more

I brought this RAM for a 11 year old HP Pavilion dv6700 laptop that had been given to me by mother-in-law which already had 3GB of RAM with it, The Laptop itself believe it or not was still in very usable condition which after I doing some TLC and upgrading/replacing most of the laptops system parts (Hard Drive, RAM, Battery etc...) I was able to upgrade the original OS, Windows Vista to Windows 10. This RAM made it possible. PROS: - At around $18 very affordable making the upgrade worth it. - helped make the Windows 10 Upgrade possible CONS: - None Overall: If your thinking of upgrading your RAM on very old hardware look no further, Highly recommend it. SPECS: HP Pavilion dv6700 (2007) OS: Windows 10 Pro (Originally Windows Vista Home Premium) CPU: Intel Duo Core (1.83 ghz) RAM: 4GB (Max capacity, originally 3GB) Hard Drive: Samsung 850 EVO 500GB SSD (Originally Western Digital 300GB Mechanical HD) Video Card: Integrated Intel Mobile 965 Video Card (VGA output) Ports: 3 X USB 2.0 Internal Nic: 100mb Realtek RTL8101E Family PCI-E Fast Ethernet NIC WiFi Nic: Broadcom 802.11g Network Adapter (Broken)/LB1 AC600 Dual Band USB Dongle ROM: DVD/CD Writer Webcam: Integrated 720p Webcam Read more
