Review on Yongxinsheng DDR3 8GBx2 ( 16GB Kit ) 1600MHz Desktop Memory PC3-12800U CL11 240 Pins 1 by Jay Blo

I bought 2 sets of YXS-PC3-14900 16GB. They should move into the Intel I7-3770 and Asus P8Z77-M Pro computers. Unfortunately, they don't boot or run faster than the base 1333 speed, regardless of voltage or timings. Once it's booted up, it doesn't take long before they crash on a normal memory test. I used them in my old I7-2600 and B75M and they've been fine since April (now September). Now 2 out of 4 modules crash almost immediately on a memory test at a base frequency of 1333. I knew I should have brought them back immediately instead of trying to use them on systems that aren't used often. They only have a 30 day Revain guarantee with no real seller guarantee.
