Dynamic does not work on my P55-GD55, too. I flash back to V1.3(Dynamic) Which Roman psoted before , it works well. So I didn't test SSV2. I meet CMOS Checksum Bad,too. It seems that each time the BIOS is Flashed, the system will say this message. But I have a question,please.. I tried using AMI SLIC Mod tools V1.42 to mod the BIOS V1.4, the tools give me no choice but only Dynamic can be chosen(SSV,SSV2,SSV3 are in gray and unseclectable) .So how to make SSV2??
You might want to try an older version of that Bios and see if they suffer from the same symptoms. If you find one that works properly we can mod that version.
