Thank you sergio ! It wasn't anywhere near stable though, just a screeny.

i.e. your post in the q9650 thread, thanks for that as well ... i won't be scared to put 1.5v+ for MCH and VTT, as long as it is for short term benching...

If i want to run SATA ports in AHCI mode i must enable both "Sata RAID/AHCI Mode" => AHCI Mode and "Onboard SATA/IDE Ctrl Mode" or just "Onboard SATA/IDE Ctrl Mode" => AHCI mode ? 2 HDD's, no RAID function.

I believe the first one is for hard drives only, ACHI is faster than the default. But be warned, for XP you will need to install the ACHI drivers during install...

The second i believe is for optical drives, correct me if i'm wrong? If i set it to ACHI it loads discs faster etc...

I have a bit of a problem that i need some help with.

Basically, i can boot 500x8 and run blend for a while (with 1.28vtt, 1.30mch), not tested for thorough stabilty yet, but it runs for a good half an hour or so before i stopped. But, i went back down and tried to make my way up from 485x8, and it seems i can't get it to even run more than 3 tests of blend I tried setting the exact same settings as 500x8 and it still doesn't pass 3 tests, i try more voltage and it makes it worse, i tried less and no difference. I messed with the amps, and skews and still can't pass more than 3 tests...

I then gave up and tried going for 495x8.5 for a 24/7 clock (4.2ghz... 4.2 is 99% stable at 467x9 at the given vcore), but yet again, it doesn't pass more than 3 tests. I tried 500x8.5 with the same settings and it went on for 20mins but i blue screened, it doesn't make sense.

I can get 480x8 stable and 500x8 sort of stable, but 485 to 495fsb seems impossible to get stable...

Any thoughts?
