Hi all

for information only. I have fake boot if set

cpu voltage - Auto
cpu ratio - 45

everything else is at default !!

Bios version V10.5 (i have tested also V10.3 and V10.0)

I need a cmos reset after this settings.

if someone has the same problem, I would love to know.

I have already contacted msi

what is fake boot exactly ?

[Ex Forum Mod]

 Have you tried with EuP2013 disabled in BIOS?


 "what is fake boot exactly ?"

 For most people what it means is that when PC is turned on it will start and then 1-2 seconds later shut off and then restart normally. Intel chipset MBs have done that for quite a few years. I 1st saw it myself when I had a P35 Neo-F & P45 Platinum.

Yes, it's the same thing

This is an overclocking problem.  Try a lower CPU Ratio.

Overclocking problem with vcore auto?? it's a joke?

this cpu works great with 1,280V on 4500Mhz

why not work with vcore auto?

There is a considerable difference in Intel CPU's as to OC ability. It's called luck-of-the-draw. Jack is correct, your CPU appears it can't handle a 45X on Auto voltage. It's just the way it is sometimes. Another exemplar might even do 46X or 47X on default voltage. Is the 1.280v. confirmed by digital multimeter at the V-Checkpoint? 4.4 - 4.6 range is an average one might expect, but not an absolute guarantee on default voltage.

Auto voltage is not the default voltage for the cpu. Is the voltage that the motherboard decides to send the cpu (according to the frequency)

Auto voltage --> 3,7 Mhz --> 1,2Volt max

Auto voltage --> 4,5 Mhz --> 1,4Volt max

but in this motherboard not works (for me at least)

The "luck-of-the-draw" has nothing to do

[Froggy Gremlin]

  Default voltage for the CPU I suppose could also be called it's VID?

Luck-of-the-draw has a lot to do with it. Some CPU's won't even do 4.4 on Auto (default) voltage.

Yes, but when you set vcore as Auto in the bios, the motherboard increase the vcore according to cpu frequency

If the Vcore default for 3700Mhz is 1,25 Volt, when i set 4500Mhz the bios increase the Vcore maybe 1,4 maybe 1,5 but this not works with my motherboard

Perhaps I can not explain, sorry for my english

[Froggy Gremlin]

Understood. CPU V. when in Auto has it's limit that the UEFI/BIOS will allow it to reach. I don't know what that limit is, but apparently, it does not go high enough for your particular CPU to maintain stability at 45X. That is why Jack recommended to lower the mutli to say 44X. One feature of the bclk is that it is nice to be able to tweak it some to reach the highest clock possible on Auto. The negative to using bclk is it may have long term consequences, and it increases the RAM speed which can cause it's own set of additional problems.

Yes but it is strange...my CPU has no problem in overclock at 4500mhz with 1,280...

however, now i have undestend 

thanks man
