[citation][nom]bounty[/nom]If you guys had stability problems at 3.6 and 3.8 (at almost 1.5v) and had programs wipe things out to the point that you had to re-install the OS I'm guessing you benched at a non-stable OC (long term). I think you need a do-over at 3.5 otherwise it's not helpful. We wouldn't run our systems that unstable, and the other sbm's you built are/were stable. You could give the 7300 another shake next month to check if you just had an unlucky CPU, or the 5200 to see if it was just lucky etc. I just built a 5200 + GA-EP43-DS3L for a friend that went to 3.6 on stock cooling and 1.3625v easily.[/citation]
Hello bounty; Just to clarify... Considering the week of stability and performance testing, issues were quite rare and minor. It still seemed valuable added info for the readers to mention any issues that arose. The error in Vantage could have been hardware related, but also could have been software related. The problems could not be repeated in any other ap or diagnostic. Also, I'd say one single cold boot issue is hardly reason to think a torture tested setting is not stable. As mentioned, yes, Vcore was higher than desired but again temps were fine. 3.6GHz and 1.4V was considered, but would have been quite the disappointment vs last month.
I shouldn't say the E7300 won't return, and you are right if we get one with lower VID it may do much better. But it will have to be priced a bit better vs the E5200. $28 at the time of submitting components wouldn't have been too bad. But if down the road the CPU price difference could put a GTX 260 or HD 4870 into the system, you won't see the money spent on the E7300.
