Review on HP VH641AT 4 GB DDR3 PC3 10600 by Sean Patel

They were ordered for an HP 8GB laptop and do not work with this device. I only installed one and it didn't work. I had to reinstall 2 memory chips of 2GB each. I had an older HP unit with a slightly slower processor and decided to confirm the chips were bad and both worked in this unit which was NOT rated for 8GB. The processor in the first device was Intel I3, and in the other AMD (the accepted one). Both run Windows 10. I still want to update the original packaging. I did a google search and found other people with the same problem but no solution and contacted HP but they didn't reply. I hope you will investigate and if you need any further information from me please let me know
