that tells me F4 has a Auto vcore increase to stabilise the OC.........like someone else mentioned hereQuote:

dinos do you know where the vcore read point is??
seems true, I think its the same for Gigabyte DS4 F3 BIOS. Is there any good apps that shows vcore and vdimm? I got cpu-z and giga easyt and it sucks since both apps are reporting wrong on some thingsQuote:

... or not! :DQuote:

hmm I didnt see that option in speedfan before I must be blind lol
i think kunaak has it all covered in his threadQuote:

I have OCed a few of the pentium Ds and they seem to do that, the first core will be perfectly stable and the second one will go nutz....... this is on 3 different chipsQuote:

Check your voltages and see if thats what you are getting on auto, guys.
That being said, I started from scratch and am stable at 3.2 on this "stock" voltage setting with the F4 BIOS. I was setting 1.45 manually to get this high, with this same BIOS before I started over. Very strange indeed.
As Fry from Futurama would say, "Magic, got it."
EDIT: I take that back the board is adjusting for FSB. If I set it to 266, vcore shows up in CPU-Z as 1.325. wtfmate?
no overvolting with two different DS3 mobos i've had
you can' overvolt by 0.1V man that're no way
proof is in the pudding after changing to this bios users are seeing this happen and previous bioses AND setting fixed vcore shows different results
same here. vcore at normal and fsb at 430 shows 1.424 in CPU-Z
YES YES YES
F4 retail bios - def VCore setting is ~1.42V not 1.32V so be careful !!!
cpuz shows correct VCore...
But why is Vdimm set at 2.1v stock on F4 bios? If I even do a +.1v it kills the board and I have to either reset cmos or try to get in the bios fast enough to set it back to normal. My Patriot only need 1.8v. It's fine at 2.1v but just seems like unneccasary and unwarranted heat.

I have just about had it with this crappy F4 bios. Using F3 I was able to get a dual prime stable OC to 3.2ghz on my e6400 but now no matter what I do I just cannot get dual prime stable with similar settings even starting from scratch. I have tested and tested for the last 3 nights with F4 and for the life of me after about 500 reboots and changes I cannot get this system to stablize. Back to F3 I guess.....
Well, in BIOS, I did not add any voltage to Vdimm, and both EasyTune and Speedfan are reporting Vdimm is at 2.1. if I use a +.1 Vdimm, it won't boot up at all or just turn off after about 2-5 seconds.Quote:
