    hi This is the memory that the manual says is supposed to be in my computer : System Memory
    Three 168-pin DIMM, 5V/3.3V, SDRAM/EDO
    Error Checking & Correction (ECC)
    Table Free Configuration, Auto banking...... I am using non-parity pc133 and pc100 Is this ok?? Or do I need the ECC type ram? I find that the sytem lags a bit so I'm trying to figure out whats going on. http://www.sprintcomputer.com/motherb/h-m748mr.html Thanks !

    Hi Cadeau,
    If I read you correctly you are using both 133 and 100?
    The memory will run at the slowest speed. I recommend that you use the 133 only or the 100 only. A check of your system from the manufacturers web site, you are using the correct memory.
    But as I said I would you one or the other but not both.

    ECC is used for error correction, its more expensive and rarely used in home systems. Your board will use 'non-parity' ram just fine. On a side note this is a very cheap board that I have problems with before. Its a PCCHIPS board and I'm no big fan of them.

    If you like post your system specs, your start-up, and your problem and maybe we can help.

    Edit: Missed the part that you are using PC100 and PC133 at the same time. I strongly recommend against this as i have recieved an email from a supplier that was recieved from a memory manufacturer against using pc133 ram in older systems and with other types of ram. And from personal experience I agree.

    OK thanks you guys. Ill switch to pc100 only then. A problem that I just developed is the LCD read out on the front of the computer used to read 66 ( I'm assuming 66 mhz) but now it reads 8. This has started since I installed the 128mg of pc133. I have since removed the pc133 but the LCD read out still shows 8. The computer just seems to be responding much slower then it did a couple days ago. A real dog!

    I wouldn't put much faith in the display. I'm guessing this computer was upgraded from an older computer? In the bios you may have to change some settings. Make sure your CPU settings are correct and maybe possibly load optimal values or performance values. Then make sure UDMA and USB is enabled.(If I remember right you had a post regarding changing sttings in the bios earlier)

    FWIW, I disagree with the opinion that ECC memory is not for "home systems". First off, it's not all that expensive, and it's great for any system where you don't want potential mystery crashes, which is all of mine!

    I just did a Pricewatch scan for ECC and non-ECC 512mb DDR 2100 memory. $67 for ECC, and $39 for non-ECC were the cheapest prices. I don't know about the rest of you, but I can easily justify $28 for a more reliable system! :)

    BTW, all of my systems here run ECC memory, so I do put my money where my mouth is.
