My temperatures are perfectly fine (idles at 32/30 and loads at 47/45), so they are not causing the problem. The system is 100% stable at the clocks/voltages in my sig. It'll run memtest for hours and hours with no errors, I can run ORTHOS or OCCT for 24+ hours with no errors or anything. It's known to be stable.

I increased the clock from 246x13=3198 to 250x13=3250 and the computer boots fine. I also scaled the memory back so that instead of running at 1000MHz, it was running at 810MHz, so the memory was taken out of the loop. It's not going to cause any problems. I fired up ORTHOS and temperatures remained similar, but after 1.5 minutes, I got a BSOD with this message:

"A clock interrupt was not received on a secondary processor within the allocated time interval."

So, I upped the voltage from 1.5125V to 1.5375V and tried again. It crapped out after 8.5 minutes this time. I'm about to try increasing the voltage to the maximum I can on the board, 1.5625, but it seems ridiculous that I'd have to run this much voltage to squeeze a tiny bit more out of this chip. I've seen so many online that run at 3.3, 3.4, and 3.5GHz easily, so I'm frustrated that mine won't. I understand that I may have a crappy chip, but I was wondering if anything else could be causing this BSOD?

Note: I'm running the latest BIOS (1302) and have the most up to date chipset drivers, so updating those doesn't need to be addressed. I've read online that Vista can cause this strange error message, but I'm unsure of that. Any advice would be great.

Sounds like you really are just hitting the chip's limit. When you have to start increasing the voltage that much to only get a little farther, you know you're very close to the wall. I would just run it at it's previous speed, as it seems like it does well at that speed. If the chip is just hitting it's limit, though, there isn't much extra you can do.

EDIT: And I assume you're taking the HTT multiplier down as you up the FSB.

Yes, I've lowered the HTT multiplier down to 4 from 5. I was thinking I had hit the limit but was hoping I hadn't! Anyway, I downgraded to XP Pro from Vista in an attempt to fix this, plus I like the faster OS. I'll post results if I'm able to get further. We'll see!
