Mem Upgrade

  1. Need to add additional 256MB RDRAM.
    Anybody have an online web site for this that is reputable?
    Which manufacturer is best?


  2. www.pricewatch.com

    Of course, from there you need to make sure the memory is compatible with the memory in your system. That's where the fun begins.

    I dont believe Crucial makes Rdram memory. If I were you my first choice would be Samsung. If they dont make the speed you need my next suggestions would either be Corsair or OCZ Technology. I'd pass on the kingston. Beware of memory sellers on pricewatch. Lots of those companies buy the chips and use their own pc boards. Lots of quality control problems. One of the most reliable and cheapest places on the net to buy computer parts is www.newegg.com

  4. Thx for the help Sterling.
  5. Anybody purchased memory online?
    Whats a good reliable source?


  6. I have purchsed memory online thorugh www.crucial.com and have been very satisfied...

  7. Samsung & Siemens ...
  8. Crucial has top-notch service. I had a stick go bad after a couple of months, I called support, and they cross-shipped another stick. Had it the next day.

    They are very helpful if you have any questions at all.

  9. I have 512 MB of RAM. If I went higher, what kind of improvements can I expect? Im running dual Pentium that runs at 866 MHGZ.
  10. Presuming you are running Win2000 or XP Pro...
    Increase of ram probably doesn't result in significant increase in performance.

    With Win2000, you can check how much memory your setup is using. With all your trading programs running, check Task Manager (ctl-alt-del), click Performance, and see how much total memory your system has available and how much you are using. If you're maxing out, adding more ram might help. If not, adding won't help much... it will just increase the amount of "rarely/never used" ram in your system.

    With 512 MB now, your "page memory" should be set at 1024. That should handle just about anything.

    And if you do buy memory, my experience with Crucial has also been good.

  11. I have never had problem with using cheapest RAMs

    Now I have Athlon XP 1.4Ghz system (266 bus)
    and I combine with PC100 and PC133 SDRAMs and using as PC133.

    I think that PC100 and PC133 use same mem modules.

    but its all depends on mobos

    What kind of motherboard do you use?
  12. Where do I set the "Page memory"? Also, how would increasing the memory on my video card improve performance?? Im using 2 Matrox G200 MMS with 8 MB of memory....7 flat screens.
  13. The absolute best ram is recently manufactured by Corsair.
    But their supreme quality is reflected in the higher price. They allow the most aggressive ram timing and thereby are absolutely stable. If you can afford 'em, get 'em ;)
    just my opinion

    But with Kingston Value Ram you can do nothing wrong either
  14. Page memory is the memory your system uses for swapping in case it runs low of ram.
    Withing XP you would adjust it this way:
    My Computer -> right mouse button -> properties -> Advanced -> Perfomance Settings -> Virtual Memory -> Change

    Increasing your Graphic's card memory wouldn't improve your system's overall speed. Although more graphic ram can increase display speed. But this shouldn't be too much of a concern for traders but for gamers =)
  15. Go to My Computer/System/Properties/Advanced/Performance Options/Change and set Virtual Memory Initial and Max to 1024. This also keeps the page file contiguous instead of having Windows scatter it about the HD.

    Even 8 mg video ram is probably overkill for a trading environment. (Graphics intensity is low, unlike gaming). Adding more video ram probably won't speed up performance. One thing that might speed you up a little is to set your display to the lowest resolution and color intensity you can live with. I use 1024 x 768 and 16 bit color, on 4 19" monitors.

    7 flat screens? Haven't run that many, but if you've got them working, then all's probably OK.

    Also, I recommend Norton Utilities (or System Works). The One Button Checkup feature is an easy way to straighten out little gemlins which sneak into your system + the defragger is 10X faster than on Windows OS. I've been using Norton for 4 years and wouldn't consider having a trading computer without something like it.

    PS My old computer, a PII 350 with 192 ram was almost as fast as my P4, 512 ram, for the trading environment. Therefore, one must conclude the speed/efficiency limiters are not the CPU and inadequate ram.
  16. The memory comes in anti static bags.
    Any special way to open this type of bag?

  17. no, just handle with care and touch it only "unloaded" .. you might touch a heater or similar and then take it at the fringe
  18. Not really all that sensitive, though you want to avoid obvious static electricity situations. Good idea to ground yourself just before opening.
