Default what holds back high bclk?

I am having issues breaking 220 blck. 220 works great. 221blck will not post and results in a '6f' diagnostic error on my lcd. Now I've tried raising all my voltages damn near as high as they'll go and I still can't break this limitation. I've been told the CPU will go significantly higher than this as well. What voltages/settings help w/ a higher blck?

Have you tried 225 in case it's a "hole"?

Yes. As well as 230, and a number in between.

One consistent factor in all the high Bclk's really seems to be raising the PCI-E bus clock. Of course, if you raise it too high, you've got GPU and SATA stability to contend with. Wish I could vouch personally for that, but my own board will only go up to 102-103MHz w/o hardmodding, which is a common complaint about the board.

Yup try raising the PCI-E clock a little bit. Some people say it damages hardware, but doesn't overclocking anything do that lol? If that doesn't work, your CPU is already working at an amazing speed on air. Anything past 200 BCLK is an outstanding OC. DO you REALLY need to go any higher than 4.3 GHz?

I am curious to hear about what your voltage settings are for your 4.3 OC on air

Probably need to do the hard mod to the MB. Usually the wall is at 222. Unless your MB is the 1.6 version (from what I understand). The hard mod enables you to up the PCI-e clock for getting past the 222bclk wall.
4.3Ghz is a very nice overclock for air.

What are your settings lowfat? All of em.

Actually w/ the new CPU I've had it up to 4.6GHZ semi-stable But I'll be going under phase in the next few weeks, so I don't want to be limited by my board.

Interesting, so a hardmod will allow a higher PCIe clock but still not to get SATA/videocard boot issues? Do you have any more details on this. Next time I reboot I'll take some pictures of my bios' settings.

Are there any boards out there that will clock higher w/o the use of a hard mod? I am not a fan of soldering to tiny SMD's.
