Try other sata ports. According to Bit-tech there is two separate controllers on the board. http://www.bit-tech.net/hardware/motherboards/2008/09/29/asus-maximus-ii-formula/2 Failing that, maybe you should try a fresh install on the SSD in AHCI mode with the latest SSD Firmware It could be a faulty SSD.
Well i tried the "Speeding SATA port" and it booted in AHCI mode, but the speed was halved, so i switched back to the normal one and it booted. Windows must have downloaded the IDE drivers when I reverted back to IDE mode. Was going reasonably fast but then i activated rapid mode... HOLY CRAP. Sequential Read.... 2228 MB/s Sequential Write.... 1209 MB/s Random Read... 62408 IOPS Random Write.... 30489 IOPS That's according to the Samsung Magician software anyway.
Yep, the Samsung Magician software tells me it's running in AHCI mode, i don't know if those speeds are good or bad, but to me they are the fastest it's run at since i installed it so i'm happy. Thanks
Same problem just happened, had my PC on for about an hour and a half, and its just gone again.... Think i'll just send the Hard Drive back and try a replacement, if I get a second faulty one in a row I will ask for a refund and stick with mechanical drives. Saying that is there a way to diagnose whether Sata ports are working correctly, these issues only started happening when i connected my SSD even my main drive now has issues, (PC doesn't boot after I D/C SSD)
