Success: llano + 133bclk

After weeks of trials/tribulations i've managed to get 133bclk 🙂

Here are some benchmarks

The last hurdle was the sata/ahci
After reading many reviews in denial, looking thru the kernel source for linux/bsd, and firing off a few emails to reviewers and a gigabyte dev, it became clear that my issues were most likely not bios related.

I've discovered that the first 4 sata connectors become useless when AHCI is disabled
but connector 5 and presumably the esata routed thru port 6 should function.
sound and usb all function properly

There appears to be two sata controllers in the A75, when set to IDE mode they get routed to the secondary legacy controller which appears to be a problem for the drivers. Linux forces AHCI mode for this chipset presumably to overcome a suspend/resume issue.

Also setting the gpu speed you must break out the calculator ie: 700MHz is really 7xbclk

very happy with this now that i've accomplished my goals
All that's left now is to buy a $25 pcie to sata card so I can use my secondary drives and cdrom.

Impressive on your part! Not so much with AMD that you have to go through such great lengths for a half decent overclock on an unlocked llano.
 
hm, but it's only marginally faster? in gaming, that is. The apache obviously much faster. Can you bench Webpage rendering speed in chrome or something?
 
I added an equal clock comparison
3.4 vs 3.4
the apache benchmark is an aberration, maybe I should rerun back at 1866 speeds again

but the gaming benchmarks seems to get 12%+ improvement in going from 1866 to 2133

I tried hard to get higher gpu clocks, but my chip seems to top out somewhere between 705 and 738

overall i'm happy with things
currently running 3458MHz 700gpu 2133mem

The next mem divider would put my mem at 2481 (this is likely why they say 2400+ on the box)
I don't expect that to be possible without very loose timings and high volts
I don't plan on pushing the bclk off 133 for normal operation

also worth noting is I had to set my mem to 2t to get it at 2133, where it did 1866 at 1t

Fun stuff 🙂
