    i have a 9550xt with hynix 2.5ns flash with sapphire 9600xt bios(i decrease core to 425mhz and run with normal memory as default 9600xt fb). :)
    the card wouldn't work or start function when the memory is below 325mhz*2.
    when i run 3d mark 2001,my pc is freezing after one of the test is running. :mad:
    i don't not what is happen.Can't somebody solve my question.

    The thing you posted here and title of your post doesn't match.. how can a successfully flashed card contain problems? :D

    Anyway, my guess is that don't use a 9600XT BIOS.. 9550XT cards are not scaled down 9600XT cards.. they are just normal 9550 with a better memory/core clock.. I think they don't have those 9600XT features (temp monitoring. Overdrive. etc..).. Try flashing with a 9600 Pro BIOS instead..

    I have a 9550 gecube extreme platinum with rv360 and 2.5 ns ram. When i install drivers,winxp recognizes the card as 9600xt card. But there's no temp monitor.

    i would expect problems with flashing from 9550 to 9500XT, best bet is to go for the 9600 pro bios or just the 9600, due to the lack of temp monitoring!

    Have you actually looked at the core itself? Or did Ati Tool just tell you it was a RV360 ?

    Yeah.. My Sapphire 9550 card also shows up as 9600XT with RV360 core when I flashed the card with ANY 9600 BIOS.. I must make it clear that ALL 9550 cards have RV350 core..

    I asked that question because my 9550XT shows as a RV360 core in Windows. But when I was replacing the HSF on the card the core was a 9550.

    What exactly do you mean by the core being a 9550?

    I dont really care what core it has. I can OC it up to 540/420(840) (stock cooling),and win XP recognizes it as 9600XT. What do i need more? Even it has rv350 core who cares. It has 2.5 NS so basically 420 for memo is not hell of an OC. When stock should be 400mhz for 2.5 ns memo.

    How many 3Dmarks do you get with that setup? Also are you sure you get those overclocks on stock cooling? Cause they are pretty dam high.

    Why high? As i read 500 is stock for rv360 core.
    And 400 is stock for 2.5 ns. So 540 is not even 10% of oc and 420 is bad oc for 2.5 ns memo.
    So i dont think i got good OC with this settings. Only thing that im satisfied with is that i payed it about 110 USD.

    Yeah but you said in your first original post you had a 9550XT which uses a 9550 core (unless you have visually seen the core itself and prove me wrong) So since the stock 9550XT speed is 400, a 140mhz overclock is pretty dam good! But yes the memory overclock isn't the greatest overclock.

    I'm not sure about the 2.5 ns reaching only 420, try getting some cooling, I got 2.8ns and mine's at 650. And that's before I install my new ZM80 + OP1 in a few days =)

    I meant 420 (840). 1000 : 2.5 ns = 400mhz (800 ddr) so 20 mhz is 5%. Not a good OC.

    9550 core doesnt exist.It is often written on the core itself ,but it doesnt exist.9550 card use or RV350 (9600 core) or RV360 (9600xt core).
    So,atitool recognizes mine as 9600xt (RV360).Stock for RV360 is 500. 540 is not a good oc AFAIK.
    But if i look to my default clocks in its bios (400/300) , i can say that 540/420 is a good OC.

    funny thing thou, I have a gecube 9550 xt and tried several types of 9600 xt bioses under the bios section and i didnt get any luck on boot. Instead it gave me a black out screen. There is only one 9600 pro bios which is compatible with this card. Sapphire 9600 pro FB.

    I heard that some 9550's has a RV360 core.
    I suppose it depends if you bought the cheap 9550 version, or a better one.
    My bro has a ASUS 9550 GE/TD, an I clocked it to 415MHZ core, and an insane increase in his mem.
    It has a sad 5.0ns, but I put some tt heatsinks on it, and it went WOW.

    he has a +2400 and 1GB ram, and gets almost 4000points in 3d03
    not bad if I think os

    How much did he clock on the RAMs? I still don't know how to decipher the number codes on the GPU core.. I've got a 9550 also with Samsung 5.0ns RAMs.. I only can clock the core up to 440MHz with the stock cooler and up to 230MHz (460MHz DDR Effective Speed) for the memory chips with no heatsinks.. want to try to put some heatsinks when I got the time.. :p

    it's worth it's money bob.

    He reached almost 300MHZ with it.
    his card now runs stable@ 389 MHz / 284 MHz
    with his +2400@+2800 he runs 3d03 around 3600

    ofc, my 9500NP@9700PRO runs it @ 5400 :p

    It's almost certain an 9600XT BIOS won't work because the card doesn't have a built in thermo probe so when the BIOS checks for it, it won't find it.

    Now, memory timings are a different thing, I've compared 9550 and 9600 bioses and the 9600 timings are more aggressive. I've edited my 9550 BIOS to match a 9600 BIOS and I'll be doing a comparison between them to see if there's any real differences.

    I got today a brand new gecube 9550 extreme edition,all ok recognized as 9600XT (rv360) and guess waht? Overclock from stock 400/250 to 450/370 ????? Whatta f**k? After that i get artifacts??? I put back previous 9550 extreme and it runs 540/420 without problems?? It seems that u have to be a little lucky to get a good OC for a gpu. I saw later that 370 for memory i can get because of 2.8 memo,not 2.5 like previous one.

    RenconCX, can you please post the 9600 memory timings (possibly side by side with 9550 timings). Also, a performance / oc-ability comparison would be great. Thanks.
