PC100, PC133 and DDR

I am trying to upgrade my system, duron from pentium 3. I need new motherboard to go with my duron. I'm trying to be cheap here btw. In order to save costs I'm thinking of sticking with my pc100 ram that I have right now. What kind of performance will I loose by doing this. I can't afford DDR and I want to make sure that going for the pc133 will be worth it. Can anyone tell me what i can expect from a duron 800 matched up with pc100 ram compared to pc133 and DRR? Thx.

  1. I suggest getting some good CAS2 PC133 RAM from Crucial or Mushkin.

  2. The price difference between PC100 and PC133 is so small that you may as well go for the PC 133. Besides, RAM is cheap right now.

    Why do I even try?
  3. the thing is that i already have 256mb pc100 ram and i wanted to know if the performance boost from pc133 is pretty good.
  4. Do you know if your old memory is Cas2 or Cas3. I think the difference between these two is greater than between PC100 and PC133. I could be wrong though.
  5. even if you get the CAS3 ram, at 133 you should be able to run it at Cas2 on 100mhz


    -AMD's are not for the faint of heart... Intels? those are for newbies :o)-
  6. Since I am looking to replace my 256 pc100 (cas3) with 256mb pc133 on a duron system I want to know if the performance gain going from pc100 to pc133 would be enough.
    The Clock cycle is 10 ns so isn't the standard 7.5 now?
  7. I consider memory to be crucial part of a system.
    I have 256mb 7.5 pc133 micron I paid $140 for 2 mo. ago.
    I overcolcked to 149mhz and got a big perf. jump!
    Now it's less then $100. 200mhz DDR is $70 for 128mb.
    CAS 2 and 2-2-2 are better then 7.5 but I think there more $ then 200DDR.
    Get the best you can afford or use your 100 & wait for the $ to drop.
    Recomend my duron 600 (oc to 1000) or athlon 850 is cheap.
    Mboard: abit or asus (oc'rs)

    Good Luck Kelder!
  8. Thx man, that was a big help. I think I will be replacing my pc100 with pc133 for overclocking sakes. DDR is just way too expensive right now. This machine is meant mostly for rendering so memory is a huge part of the machine.
    Any brand you'd suggest I use?

  9. Are micron / Infenion good memory for overclocking? If not, what are?
  10. cas 2 is faster and more$.
    cas 2-2-2 is even better.
    cas is the time the mem waits before acting.

    cas 3@133 is cas 2@100mhz.
    Micron is good mem for a good $
    my cas3 133 is pretty good. it oc'd to 149.
  11. thx for the info
