Are you using a 125mhz strap?
If so go back a few pages and read my post (pg. 732).
When Jpmboy talked about hitting the red, normally that would be correct, but in the case of 125mhz strap it's not quite right
Pretty sure you need to start with a +0.2v offset (99% sure this is right but it's been a while so start with +0.1v 1st).
Sounds like alot I know.
You can try a manual voltage 1st and see if that boots.
Try 1.2v manual.
If that works, figure out the offset, manual voltage will get it stuck at 1.2v (no idle), so when you try for an offset you won't wanna reach the same level in the bios readings.
If you got an offset reading 1.2v in the bios then you're in trouble when you goto windows...
Anyways start with an offset of +0.1v, sounds like a alot but if your on a 125mhz strap it's not.
Double check the bios reading before booting windows to make sure it looks halfway normal.
Boot windows if you can, check cpu-z with some load like aida64's benchmark (not a huge load
See if it reaches about 1.216v on the vcore, that's pretty much stock voltage readings right there.
Hit me back if this works out for ya
You could also use hwmonitor32, but I recommend cpu-z, because I know that 1.216v on that is ruffly stock (-0.005v offset at stock strap).
Oh and start with a cpu multi you think is stable at stock voltages and verify it before moving on up.
I made a post on the asus forums for someone asking for help with vcore.
I recommend lynx, there's no real difference between it and ibt but I like lynx better.
It'll get you close enough to stable voltages, but it won't get you to the very edge.
It's probably good for 0.025v or something like that.
Getting closer then that (again I'm not sure exactly where the cut off is), requires running over 5hrs of y-cruncher (6hrs min, I always run 8).
Lynx will get you just a few steps away from getting the perfect vcore.
At the programs stock settings, just run it, 15mins later you're done.
There isn't anything quicker then that, I've checked.
I checked mine at 4.5ghz.
Because my cpu is SOOO close to getting stable at stock voltages at that speed.
So most programs can't detect errors at all.
I ran over 12hrs of lynx as well as ibt separately (manually set to it's max mem values), not a single program other then y-cruncher was able to show me errors.
And even y-cruncher took hours to do so.
Oh I forgot, I did not check prime though.
I haven't got around to it yet.
