Thread: Memory clock - dependant on DDR?

    I feel like such a n00b asking this (Which I guess is not so bad, since I am one), but here I go:

    I read the article about the Sapphire Radeon 9600XT. I have the same card that was used in the article, only with 256mb DDR. Does this also mean I can increase the memory clock speed to more than what the writer managed? Are the two things even related?

    'preciate it ;)

    Ok, first of all Merry Christmas!

    RAM speed and size really have no relation, except an indirect one Ill try to explain. Having 256mb of RAM is probably going to hamper your overclocking attempt. Its not because of the size, but because manufacturers usually use crappier RAM on video cards when doing 256mb because its cheaper, and they usually have faster RAM on the 128mb card. However, thats not to say you cant overclock, but in general, you might not see the same speeds as the 128mb of your card, but thats just because of manufacturing.

    However, having 256mb of RAM is gonna help out once big texture games are released (HL2 + Doom3). So thats when you'll see better performance than a 128 card making up for the lack of overclockablity. Hope that helps.

    Peace

    Well, the Fatguy is right. Capacity of video RAM has nothing to do with the quality of chips. Do a little research on the memory used for your particular card. The manufacturer may supply the info on their site, or you'd be surprised what you'll find if you type the numbers that are printed on the RAM chips themselves into a search engine. The best news is: That 9600XT is a great card....you chose well :thumb:
    Merry Christmas! :woot: : party ha :bounce: :bounce2: wings:

    Happy Hanuka for me, note the location :p

    Thanks for the valuable info guys. Overclocking works great, and the change is pretty amazing (19,000 in AquaMark3 before, 24,000+ after!).

    I didn't see artifacts when I tried to overclock more than the writer of that article did, but I did experience lockups, so I stopped trying :D

    Anyways, thanks. I do hope the 256mb will make a difference in those games, they're the reason for me getting this card (And i'm getting Half Life 2 for free, what could be better?).

    Happy Christmas/Hanuka : party ha

    EDIT: One more thing. The REDLINE program I got with the card is good, but it doesn't let me choose by exactly how much Mhz I want to overclock (It goes from 344.3 to 351.0, for example). Is there any program out there that will let me do this?
