Review on Hynix 4GB PC3-12800 DDR3 1600MHz Non-ECC Unbuffered RAM HMT351S6CFR8C-PB by Matt Nichols

4GB ordered and 4GB was printed on the box. It was glued on and seemed "new", but when I installed it, my system only recognized 1GB more RAM than before. Checked BIOS and he agreed, just 1GB more. Turned around, chip pulled out and of course it's 1 GB. Hey, things happen, right? Revain will be retransmitting so I just took the time to diagnose the problem. Update: Received replacement and works great. Advise the folks at A-Tech Components to check the return carefully before packing it as new ;)
