    So you were lucky and got one of the ones with 1.6 ns chips on the one that isn't guaranteed to have them. :) If you change the heatsink/fan for something better and put ramsinks on the memory, you'll have a card better than the extreme edition that I mentioned. :)

    You shouldn't have any problems having to do with memory for either of them. If you go with the one labeled Powercolor.X800GT_16P.256.Samsung20_050726, you will have the bios designed for the card you have, but just modified to R480; so there will be no problems there. It may not actually be the exact same bios; it could be a newer version of the bios than the one you have, but that shouldn't cause any problems, since it is still for that type of card. If you go with the one labeled Powercolor.X800GT_16P.256.Samsung16_050823, you will have one that was from a card with 1.6 ns chips. Either way, you will have one that works. If you are not going to overclock, I'd go with Powercolor.X800GT_16P.256.Samsung20_050726. If you are going to overclock, try both and use whichever gives you the best overclock. :)

    Oh...one more question

    I use a X850XTPE edited in RabiT 1.7 ... I low the memo and core to 472 and 492...

    my temps get a little more high now ... is because the bios ? I see the temp in Rivatuner.

    There´s something to do with the fan to control this ?

    I don´t overclock nothing and used the default temps from my original bios.

    look at the loging in rabit ;)

    humm.. that may work have you tested all of those bioses? using the moded flashrom on a less than 16 pipe card?

    the way i do it is bt using the non moded flashrom to flash it to a already 16 pipe card and that changes it then i simply save the rom from the card and flash back

    I used to think the same exact thing but that doesn't always apply ;) but you may be right that it would work on x800's cause i don't think it has a locked device id like other cards like 9700's 9600,s ect. :)


    the way you change drivers is go into device manager / update driver/no not at this time/install from list~/dont search~/uncheck show compataple h/w

    That's why you should use one of the modded bioses I posted. ;) BTW, I see from your scores that you got the performance boost for going to an R480 that I was talking about.

    All that matters is what the driver says, since that is when there is the change in performance.

    Yes, I've tested all of them. Besides, it's very easy for me to tell when that is the right value to change or not. You're talking to someone here with lots and lots of binary file modding experience. ;)

    Yes, it does work at least on X800/X850 series cards to change the ID. That's all I have experience with for bios modding so far.

    I'll try it and see if it works and if it gets the equivalent performance boost.

    Ok, I will try the indicated bios

    btw, new test with other bios:

    X850XT - 4143

    Same score of X850XTPE, but without my 4 pipes (#$%@ing default 8 pipes) =)

    You can see what a bios originally was by looking near the beginning of the file with a text editor or hex editor. It will usually say it in plain text, like it will say R423, R430, R480, etc.


    I learned it on my own. :) Mainly my experience with modding binary files comes from mods for game data files.

    BTW, I tried using the X850 XT PE driver with the Powercolor X800 GT bios as you said I should try and I did not get the R480 performance boost.

    no but I´m trying get 12.

    I get the bios indicated by you and here the score in 3dMark2005

    X800GT R480 - 4130
    memo/core default and the temps low to max 45oC :eek:

    Well, from the 3886 I get with the original bios, its good, dont ? =)

    I don't quite understand what you mean. Are you saying that the temp. is lower or higher?

    BTW, I'm not sure why, but it seems like the Powercolor X800 GT bios may be consistently getting scores about 10-15 points lower than bioses that were intended for R480 chips (I also got about 4130 with that bios and a little above 4140 with another). That amount of difference is almost nothing, though.


    One more thing; you wouldn't happen to be the person to whom I sold my Powercolor X800 GT with 1.6 ns memory chips, would you? He's also from Brazil. Heh, probably not, since when I mentioned this bios mod to him he said he didn't want to try it.

    My temps with the X850XT or XTPE are 59-62C and now using the bios Sapphire.X800GT_16P.256.Samsung16_050823.zip I get temps like 39-45C.

    And now I see that I used a wrong bios .. uops...I ll try the Powercolor now.

    And sorry my english ... hehehe

    Heh, if you intended to use the one saying Powercolor and Samsung16, it won't make any difference except that in programs that will show the subvendor ID, it will be Powercolor instead of Sapphire after you change the bios again, since it is only a mod of the other just to change the ID for the maker of the card. The 3 bioses I posted with Samsung16 in the name are all the same bios, just with different ID's for the card's maker. The only one that is actually different is the one with Samsung20 in the file name.

    Of course, you could flash it to the one with the subvendor ID modified just to have it be IDed as a Powercolor card, but there will be no need to retest anything.

    BTW, the difference in temps is probably caused by different fan speeds that are set in the bios. That's the main reason I was recommending using one of those; they use the same fan speeds.

    So shadowflare where do you think this performance is coming from? (it doesn't seem to be the drivers.. or is it :confused:)

    I still think it's from the drivers; it just seems to only be able to be forced as an R480 in the driver if the bios actually says it is one. Driver mods may be able to get around this, though.

    Which XT? X800 or X850? I'm assuming probably X800 because of the clock speeds you mentioned. Since Powercolor said they would only be using R480 cores on their X800 GT's, I'm sure your's has it, too. Try using one of the bioses I posted. It will get better performance than an X800 XT bios on that card. Also, using the X800 XT bios would severely limit your memory overclock and possibly gpu overclock (at least from my experience with my GTO2).

    BTW, also post your original bios so I can take a look at it.

    Hmm, interesting. According to someone there, Powercolor made an R480 bios for their X800 GT and has made it available. I've never seen that before. However, I remember when I looked at the original of the second revision bios that I posted a mod of, there was something with R480 that showed up in the bios file. I tried the bios file and it still got detected as an R423. I wonder if this is the bios they speak of? If so, there's nothing really special about it; I got the same 3dmark05 scores with it as I did with the older one.
