New ram in addition to previous, system rebooting problem

post #1 of 3
Thread Starter 
Hi,

Here is my HW configuration:

  • motehrboard: P8P67 PRO: http://www.asus.com/Motherboards/P8P67_PRO/
  • cpu: Intel® Core™ i5-2500: ARK | Intel® Core
  • previous installed ram: Corsair XMS3 CMX4GX3M2B1600C9, 1600Mhz, 2x2GB=4GB, 1.50v, 9-9-9-24, ver6.0
  • new ram in addition to previous: Corsair XMS3 CMX4GX3M2B1600C9, 1600Mhz, 2x2GB=4GB, 1.50v, 9-9-9-24, ver8.16

I started my system, after a while it reboots and after that it gave error in overclocking. I just wanted to add those 2x2GB to my previous 2x2GB. Is it possible even if they are different versions but the same for the rest?

Thanks

No, the version numbers tell you that they are NOT the same.

They have different ICs and perhaps PCBs too. Even though the "published" specs are the same, there are 31 timing parameters, not just the 4 or 5 published.

Not only are your sticks based on chips made by different manufacturers, but also the density is different (6.0 should be dual-sided, 8.16 should be single-sided).
What you could try, to see if it helps, is either dropping the frequency to DDR3-1333 or raising the tRFC (Row Refresh Cycle Time) to, say, 128 if current value is not in triple digits already.
