Please update this firmware for PX-716A to solve the UDMA problem with SB450 south bridge ... http://oskarwu.myweb.hinet.net/716a_1029.zip

Curretnly we found it's a common problem of ALL ATI SB450 problem ... We are seeking the help from ATI but no response yet ...

Hello guys , could you please test if disable USB keyboard and mouse support can solve this problem ???

Looks like a different situation from the result here , I will keep trying to duplicate the problem ... sorry for this problem ...

With improved DDR 400 4 DIMM 1T capability ... DDR600 2T 4 TCCD is easy now as well ... Try to set driving setting level 9 + data drive level 4 ... dram voltage 2.92V ~ 3.00V ...

I just got one board which may have the same problem as you guys even at all optimized and non overclocking setting ... If possible , try to leave the board along(still powered on) for a while when 4 LED is on and see what happened in the next ...

Some guys complain about the system will have 4LED problem during bios exit but once it boot , it can boot into windows ... A reset can solve this problem ... If the board does not post , it's not the 4LED problem I refer here ...

I need to collect you guy's bios setup to duplicate the problem ... First please download the tool http://oskarwu.myweb.hinet.net/RDX200/WinReload.rar Execute it under windows enviroment then 1 . Sellect Backup button 2 . Select Current 3 . Give it a file name ex : bioscurrentsetting.txt 4 . Reply with your detail hardware combination and attach this file for me to reload your problematic bios setting here ...

6/23 bios has been put as offical one and not beta anymore ... Generally , modify anything in bios that is voltage related need to be tested internally before it's released no matter it's alpha , beta or gamma ... Before the 7/04 beta bios , no voltage related code has been modified ... In order to solve that sometimes new DDR500 option will fail to boot in 7/02 beta bios , I change the protection I made before and it's a negligent fault of me ... I am in a rush of solving the 7/02 beta bios problem , I forget to do the complete testing about the modification I made because generally I did not set low " CPU VID " + high " CPU VID Special Control " in the same time and did not found the fatal bug I made ... In order to make every user happy , I have generate too much beta bios trying to satisfy every single user complain blah blah that this beta bios decrease my overclocking and please fix it and so on ... I don't really need to do all this and you can see this clearly when you have overclocking problem in other mb ... And something like this is impossible for any MB company ... I need to handle the complaint from other department because of this and this also affect which is the best version we should sent to do the validation and finally put it into official ... It's impossible for me to find a perfect one to satisfy everyone ... We have reset the validation for many times since 3/10 bios because some user compalin blah blah that my overclocking is not good with this one and fix it ... Finally we settle down 6/23 should be safe for general purpose and put it as official one now ... But there is still tons of complaint out there ... When you are trying to satisfy everybody , it's probably you will satisfy nobody ... Give me sometime ... The bug in 7/04 bios will be solved within this week with full verification in the change I made ... And I will modify the 5/10 based fix as well if you are not happy with 6/23 official one ...

It's risk to use 7/04 bios if you want to use Low " CPU VID Control " & high " CPU VID Special Control " combination to generate the cpu voltage which may mislead you into thinking it's safe to use 123%,126%,133%,136% because you set " CPU VID " to a low voltage ...

Generally , if anything related to voltage that may cause the damage to hardware , I would not put it into public beta and only release to certain people to test it first ... It's my fault to put 7/04 bios public beta ... The bug of 7/04 bios is this bios will program "CPU VID Special Control" first before setting protection to cpu voltage ... If you set "CPU VID" to a high voltage , EX : 1.55V then change to a low " CPU VID " and a high " CPU VID Special Control " in the same time , hit the save and exit ... Before the bios set the " CPU VID " to low voltage , the "CPU VID Special Control" will be programmed first without protection and may generate some core voltage like 1.55V * 1.36... Although it's a very short period , but If the cpu can not handle this voltage , the cpu will be dead ... Especially 90nm core cpu ... It's my fault and should blame me coz I have had done it :sad: ... I sincerely apologize for this mistake in beta bios before the change in 7/04 beta bios is fully verified ...

"""""" The bios may have chance to set wrong vcore voltage under certain circumstances ... """""""

Due to the a mistake made in 7/04 beta bios , do not use 'Above VID * 123%' 'Above VID * 126%' 'Above VID * 133%' 'Above VID * 136%' option under "CPU VID Special Control" The bios may have chance to set wrong vcore voltage under certain circumstances ... If the cpu can not handle the wrong core voltage , it may be damaged ... This problem has only been found in 7/04 bios and 'Above VID * 123%' , 'Above VID * 126%' , 'Above VID * 133%' , 'Above VID * 136%' are used ... If you did not use the 4 settings , it will be ok you if still want to use 7/04 bios ... Please help me to remove this bios around the internet ... I apologize for the this mistake ...

I got the board and memory today , there is a SMD capacitor on one of the dimms is broken ... I solder it back and test the two memory in my daily working FX-55 + dual channel platform ... One of the dimm(the one with broken smd capacitor) is damaged , it's not booting under dram voltage lower than 2.8V even at SPD timing and 200mhz fsb in single channel mode or dual channel mode ... After a certain period of rest(cool down) , sometimes it can boot @ 2.6V ... Most of the time it need 2.8V to boot ... The other one is complete ok ... 6/18 bios can help this situation if you set and save the dram voltage higher than 2.8V using the other good stick first and put the damaged one into the socket ... But the damaged stick perform exactly the same as the previous set I got , the damaged stick of previous set just need more boot up voltage than this set ... About the board you send , in order to use phase change cooler , the socket is filled with thermal grease ... I need to clean all of them before testing the board , this will takes some time ... I will post the motherboard result after I finish cleaning the socket ...
