Using 133 Ram descreased Perfo.

My friend own:
Giga byte GA-60XC.
P-750 Mhz.
PC-100 (64 MB).
WD20 GB.
Creative Vibra 128.
He removed the 64 RAM, replaced it with 256 MB of PC-133, this performance become so bad, the mouse moved slowly alot of time, The sound isn't clear.
When he reback the PC-100 everyhing goes ok.

  1. Bad RAM?

  2. Thanks a lot,
    We test the RAM with norton utilities,there are no errors.
  3. What OS are you on? Windows 98se is known to struggle with too much mem

  4. Perhaps your new or old RAM is ECC?

    Double check the BIOS.

    <b><font color=blue>~ BIOS SETTINGS: Fast, Hot, Unstable...That ought to work. ~</font color=blue></b> :wink:
  5. ECC lowers performance that much?? I thought just 2 to 5 percent, tops

  6. Well, it's definately not a "PC133 on a PC100 system" problem as those simply do not exist. It could be a defective module, or a BIOS glitch with SPD, you might need to update BIOS to make sure it's not the second problem.

  7. i had similar problems way back in the 98 days.... i found that reformating the computer actually worked but who knows.... also is the board still set on pc100 ram, is the bios up to date, you sure he took out the old ram, and you possitive the ram is in good nick....
  8. Perhaps running the full mem test, rather than a quick post will provide more clues.

  9. As far as I know, the only difference between PC100 and PC133 ram is the speed it is CAPABLE of running at. It actually will run at whatever speed u set it to or the MB default. PC 133 should work. I even put PC133 in a old socket 7 board with a 66 bus speed and a ALI chipset and also a Intel "TX" and "VX" as well as the old LX pent 2 boards.

    ECC ram doesnt seem to work at all on my VIA chipsetMB unless I change the bios settings. Supposedly ECC ram is for servers which can sacrifice some speed for accuracy.

    I vote for a bad memory module as the problem.
