Well, after 12 DAYS (!!!) I finally got my FX8300 ! It seems UPS lost it picking it up from Newegg, and after 1 live chat and two phone calls over the course of the last week, I was able to get another chip sent my way. I should have known this was not going to be nearly as easy as my 6300 chip, and so far its proven to be a very tough chip to figure out. I have had to clear the CMOS 4 times already, and I just can't get this chip to do what the 6300 does.
The 6300 was first tested using AMD Overdrive, just to see what that offered. That chip scaled up to firstname.lastname@example.org, and it was STILL GOING when I prematurely ended the test, safe in the knowledge that I had a nice chip. I set it for email@example.com and it ran all day with no issues. I knew going in that the 8300 ran at much lower voltage, so I set the BIOS back to default (auto everything) and popped the 8300 in and let her rip. I started off using OC Genie, and it wouldn't boot. CLR CMOS.
OK, default everything, then back into Windows, where I now used MSI Command Center to try and overclock it a bit at a time. OOPS, turbo mode still on, as my multi keeps changing and I forgot to turn off many of the things that reset to AUTO in the BIOS.
Back into Windows, and now I used AMD Overdrive (again) to see what it would do. That managed to get up to firstname.lastname@example.org before asking me to reboot. So I knew those were the numbers to shoot for in the BIOS since that was what AMD Overdrive was able to squeeze out of it. I set my multi to 20 and voltage to 1.38v (for a locked 4000mhz with no turbo mode) and it once again would not boot into Windows, requiring yet ANOTHER CLR CMOS
Seriously, the 6300 was about the easiest OC I have ever had (going back to the ubiquitous Celeron 300a@450) and this 8300, which I FULLY expected to get within spitting distance of the 6300, is not even close to it. I pretty much gave up for the evening, and left it at bone stock 3.3. Of course, Windows WEI score managed to climb from a 7.5 (with the email@example.com) to 7.6 (firstname.lastname@example.org turbo). Windows must like the extra cores compared to the higher speed.
PS - not sure why the chip didn't turbo to 4.2. CPU-z shows it stuck at 3.6. I'm reading several site that show it turbos to 4.2, but then I find others that claim it only turbos to 3.6. I have some work to do tomorrow, and I hope that I can get some more performance out of this chip.
