    Those are timings. Ras, tras, etc. I would just set your voltage at 2.2 manually and let the motherboard select the timings.
  2. So what is the fourth number 15 or 18 and why don't i see it on the sticker?
  3. Googled OCZ2RPR10664GK:
    First hit:

    Is that your RAM? Under Specifications it says: "5-5-5-18 (CAS-TRCD-TRP-TRAS)"
  4. I don't know if it is....
    On the sticker on the memory written 5-5-5@2.2-v
    and on cpuz i see under #EPP1:
    Frequency 533MHz
    CAS# Latency 5
    RAS# to CAS# 5
    RAS# to Precharge 5
    tRAS 15
    tRC 26
    Command rate 2T
    Voltage 2.100 V

    I gues its 5-5-5-15 but why don't i see it neither on the sticker nor on the manufacturer website??
  5. OCZ programs the EPP that CPU-Z reads. If they programmed them incorrectly, all CPU-Z will do is report that bad information. Notice that the Voltage as well as the tRAS are different. But, it could be that the EPP is correct.

    If you can get them to work at 5-5-5-15 and 2.1V then run that way. Be aware you may have to back off to 5-5-5-18. The website says the V is 2.1-2.2V, so start at 2.1V if things are unstable move to 2.2V.
