I just bought the 4SDA5+. Have OC'ed up to 150Mhz with a 1.6a & just vcore 1.57v & 2,5,2,2,1T on 512mb Corsair PC3200 XMS memory w/o conflicts on rebooting into the Bios. I didn't go further because most people were not able to go past 130Mhz. Have NOT loaded Win XP & stress tested board because I received an error message upon loading Win XP Oem;
"File dxmasf.dll was not copied correctly. The file "Setup" placed on your harddrive is not a valid Win XP system image. If you are installing from a CD, there maybe a problem with the Win CD."......Now, when booting w/ Win 98 Startup floppy, I get a NTLDR missing report.
If anyone has a solution to the above, please let me know as I cannot continue the installation.
It looks as if this board can OC rather well, but will know more after solving Setup problem. BTW, I disabled the LAN,USB 2.0, & Firewire because of problems with DDR400 & 8X. I thought that the instability with Sis 648 & Via 400 boards just might be from these items. I will add these items back on, one at a time, to see which one, or all, might be the culprit in limiting overclocking
