IMO do it!!! i would like to know, but do not hold me liable if it kills your m.b. best luck to ya.

killing the mobo is never good.....

I´ll do soonest the KX7 bios came out. I have a friend with another KR7 and some knowledge, and he will fix my board if he dies in the process. No pain, no gain.

If you really want to be a little more enterprising you should try to download the specs from both Northbridges form SiS site. From what I have heard they are almost the smae appart form the Dx officially supporting the 533 FSB. From what I have read at www.xbitlabs.com both of them have similar architecture.
Just be on the safe side and see that you have all the utilities necesary to reflash your mobo in case something goes wrong.
Keep us posted.

Thanks Mictlan. I´ll try the "surgery" soonest the KX7 bios came out. I´m really thinking it will work.
I have a friend of my with good knowledges and one KR7, and he will rescue me if I need. But any advices about this reflash are welcome, in case I need it.
Well looks like people are stop calling me idiot now and starting to take 2 secs to think about it, It´s good!:D

good luck Firehawk!!
as u know, i'm thinking of a P4 rig to replace my old T-Bird. so, it would be interesting to see how it goes.......
let us know. ;)

Thanks Shark :)
Tomorrow I´ll receive one Abit BD7 to see where I can go, and compare with P4S333@533. I´ll keep u guys posted.
About the KX7 bios, dunno if it will be good to me, because ìm already running at 200x8,5, and a friend tell me his Epox KT333 lost the 4:5 memory multiplier after 166mhz. But I´ll try the bios anyway, this is my idea, and if this work, will help other people with locked chips. :cool:
Don't do it.
You gain nothing from it. Read the front page articles with DDR333 while CPU is still running DDR266. Very minimal gain over lots of work, so no it's no worth it! There was also a conversion thing with the Shuttle AK31 to AK35. They found that even able to reach over 166fsb, it wasn't stable since the motherboard was never built for it.
You take a risk of killing your bios and going through alot of trouble for not much.

Good point Yodums. Looks like no big improvement, if any at all, doing this. I´ll see it in the future.
But the P4 lands are roxing right now.... I end at 2.67mhz with the Abit BD7, 3418/3386 memory score in sandra 2002. For an 0.417 unit, 2:47. FAST! I can´t go any further with the boxed cooler, I´m stuck at 1,8vcore ´till I have a better cooling. I make easy 2.750mhz, but 70°C is not good!!!!!
Then my rigs right now are one P4 1.6A@2.67, one at 2.56, and the bugged XP, who is counting my units like double, and they are not =P

I've been thinking about this, Firehawk and have come to the following conclusion:
I'm assuming that your purpose to this BIOS flash is to get your PCI bus speed back to normal (or near to normal). Before you do this experiment you'll have to check the clock generator PLL number and model located in your current mobo (P4S333) and compare it to the one located in the mobo to which the BIOS is mean to (P4S533).
If the clock generator model is the same then chances are that you might unlock the new PCI divider hidden inside the PLL. If the models are different you'll have to get the PLL datasheet to see if the PCI divider is hard coded inside it.
Recalling an editorial made by ED sometime ago, new BIOS only make available hidden features already located in your mobo, they can not add ne features to it.
If you find that the PCI divider is not locate dinside the PLL, then the only way to get lower PCI speeds will be to mod the PLL and clock generator to get the 33 MHz PCI bus at whatever speed you are running the FSB.
Hope this give you some help :)
