I switched from 0803 last night to the 1702m one and everything went smooth for me. I didn't have to clear the cmos or anything. I just reset to default settings and flashed and went back in and adjusted everything back to normal and set it to performance "the dreaded performance seting" and everything continued as normal for me. I played GTA IV for as long as the game would let me had to reboot " normal with game right now until patched" came back into windows and continued playing and no blue screens nothing to indicate an issue. My memory speed test came out as usual. The one thing I wanted to do is to try to push my over clock further but, I was to busy gaming . I will keep posted but, it seems as if the modded 1702 is fine by me.
