Dual Channel?

Posted on 2004-11-21

I have two "Generic" (Nanya Technology according to CPU-Z) 512MB DDR 400 RAM sticks in my ASUS K8V SE Deluxe motherboard. I was wondering if it is possible to make them in Dual Channel mode. Is this automatically set? Will there be any/much performance gain by using DC mode?

    You can do this through ASP but would have to schedule a task to "browse" a web page every day, otherwise it's possible if you get no visitors fro a few days they would never get the message.  I would actually say it's better to write a small VB application that you can schedule to run daily and kick out the reminders.  I had a calendering application I made once with reminders and I did the reminders through the VB Application.

    In any case, I would add another field (Bit type - 0(No) or 1(yes) value) to the table wih the expire dates and email addresses called  ReminderSent (or something similar).  You would use CDONTS to send out the email, a SQL statement like:

    sSQL = "SELECT Email, Name, ExpireDate FROM MyTable WHERE ReminderSent = 0 AND DATEADD(Day, 15, ExpireDate) > '" & Date() & '"

    I will say it MIGHT be possible to write a SQL script to do this as well, unfortunately, all my experience is with CDONTS and VB/ASP

    Hi Kane00

    socket 754(your mobo) does not support dual channel, so you cant


    socket 939
    The other big change is to move to a dual-channel (128-bit) DDR memory interface across the board, giving both Athlon 64 and 64 FX processors the same base memory specification. This is another much-needed enhancement, as the FX will now support lower-cost memory and the Athlon 64 will get a bandwidth and performance boost.

    Even though the Socket 754 Athlon 64 with its single-channel, 64-bit controller has posted admirable benchmark and gaming scores, its memory bandwidth is still only half that of an Athlon 64 FX -- or current dual-channel-DDR-enabled Pentium 4. This was the only chink in the Athlon 64's armor or area where AMD really took a back seat to Intel.
