    Excellent article. I was looking for a good explanation of memory timings. Thank you (I am from Uruguay, sorry for my bad English :)  )

    Good Article I guess. I've been wondering that exact question now that i got 2x1GB of Patriots PC2-8500 Viper Series from NVISION08. The timings are 5-5-5-15 2T at 1066MHz. When i try to lower it 1T it's not reliable. Anyways, thanks tomshardware for another good article, I hope there is a sequel to this, specifically DDR2 or 3 memory.

    As most of you are probably aware, the MHz clock speed of the Athlon 64 and Opteron is the product of the HyperTransport speed (HTT) times the multiplier of the CPU.


    Correct me if I'm wrong, but shouldn't this be written as, "the MHz clock speed of the Athlon 64 and Opteron is the product of the HyperTransport speed (HTT) and the multiplier of the CPU."

    HTT times Multiplier = CPU speed, the article is correct
