Help with memory timing is my problem. I have two sticks of DDR2 800 mhz (one with 6-6-6-18 timing, another with 5-5-5-15) rams with different timings. now im having some stability problems.

When running in dual channel mode, my mobo sets them automatically to-

The separate timings of my rams are-

ram-1 with 6-6-6-18, 800mhz

ram-2 with 5-5-5-15, 800mhz

please note that its causing some stability problem, and also has set my bus freq to 667mhz.
now what my common sense tells me is to run it in 6-6-6-18 in the standard timing section, and set 3-3-6-52-3-5 in the advanced timing, and set the mem freq to 800mhz manually(by changing the mem freq multiplier) in order to get better stability. and also what should i do with the last thing- "static tREAD phase adjust" i cant set it to zero, lowest i can get to is 1 while running in dual channel.

What do u think?

  1. What voltage is each stick meant to run at? You will have to run the RAM at the lowest common denominator. That means you'll have to run them at CAS 6 timings and the highest voltage of the two sticks. It would help if you post the EXACT RAM so we can look up the specs.
  2. well, voltage for both the rams are same- 1.2v. And they are Verico rams.

    That can't be right. Standard DDR2 voltage is 1.8 volts.

    From the webstite:
    • 667/800/1066 MHz
    • 5-5-5-15 timings
    • 1GB /2GB/4GB Modules
    • Unbuffered
    • Lifetime Warranty
    1.8 Volts
    • 240 Pin DIMM
  4. Sorry my bad...yes its 1.8v. And i think the problem is solved..My system is stable now by the grace of Allah. Apparently it was a problem with my windows 7 x64. Thanks a lot.
