Excellent Performance and Quality
on September 22, 2011
This worked as easily as Kingston promised. I upgraded from 1066mhz to these 1600mhz chips. The money was well spent. I will be purchasing an additional 8GB of these. I highly recommend. No issues with my set up which is as follows:
Alienware m17x R3
2nd gen i7-2720 Quad Core
Windows 7 Home Premium
I'm about 1 month in with 16GB of this RAM installed. I'm experiencing "freeze" problems at random which requires a forced shut down. I tested running this RAM with an HDD and a SSD and I get problems with both. Even after a clean Windows 7 install, I'm encountering the issues. I might have to return this unless I can figure out a solution. I lowered my 5 star rating to 3 for now.
It's been 3 months now. I found the answer to my freeze problem a while ago, but just remembered to post my findings here. The issue was the timing numbers in BIOS were wrong. If you need information on how to adjust these numbers in BIOS, do a quick search and you shouldn't have a problem. The numbers for my m17x R3 are set as follow:
9 Cas Latency (CL)
9 Ras to Cas Delay or Row to Column Delay (tRCD)
9 Row Precharge Delay or Ras Precharge Delay (trp or tRCP)
27 Row Active Delay or Ras Active to Precharge Delay or Time to Ready (tra, trd or tRAS)
1 Command Rate (CMD) Please note not all bios will have this setting
This ram has served me well so far. I have a total of 16GBs (4 sticks) installed and love it. I have increased my rating from 3 stars to 4 stars. If this was true plug and play (not in my case), I would have given it a 5 star rating. I would recommend this product to others.
