Anyway, 1.425V is pretty much the limit for 24/7 use.  Some people go higher, but I think that's a risk of noticeable degradation after about a year.
Do you really mean 24/7 or normal usage? My computer is turned off during sleep and work time wink.gif
I've decreased to 1.430V and doing another 15 min full load.
Seems that disabling Internal PLL Overvoltage in the begining was the problem.

1.4v on 4.5ghz if that doesn't boot then 1.35v with pll overvolt on

I used to run 4.9ghz at 1.48v on a 24/7 clock.

I just mean keeping it that way every day.

PLL overvoltage must be enabled. With it off I had problems. Cant even log to windows and kaboom bsod. Also the C states and stuff gave some bsods from times to times and now I have them off. Turbo boost is off too. Playing around some months with those i found out that all those c states stuff must be off for better stability.

I'm using an Offset voltage and like most people, I had problems with C3 and C6 enabled.  I recently lowered my LLC to about 25% ("Medium" for my board) and now I can have C3 and C6 enabled without any problems.

I'm running long test atm -> Blend Prime95 for night.

I don't have LLC, only Multi Step Load Line but I don't know how to use this one yet.
Also offset = DVID ? In my case this option is locked in bios by something else probably.

"LLC" always means "Load-Line Calibration".  So, Multi Step Load Line is the same thing.

 

I don't know if DVID means Offset, but I think DVID means Dynamic VID and that would make sense to be Offset because each multiplier has its own VID and the offset depends on the VID.

Yes but MSLL does have Disable, Level 1, 2, 3, ..., 10 and LLC as far as I've read has Enable/Disable mechanic? I have to find some info about it.

Still I have to first learn how to unlock it biggrin.gif

I tried x47 @ 1.450 - bsod 124 after 10 minutes, do you have any proposition how to deal with bsod? Maybe disable C1E and EIST would be good idea as suggested by Anarion?

It depends on the motherboard.  Mine has 5 different settings.  So, mine is multi step too, it's just that ASUS doesn't use that name.  Speaking of ASUS motherboards, some of their cheapest ones only have Enable, Disable, and Auto.

1.450V is extremely high for 4.7 GHz.

 

Do you mean you got a BSOD after 10 minutes of idling and/or just using your computer?  Or was it 10 minutes into Prime95?  Disabling C1E and EIST will not help for this either way.  Also, you're using a fixed voltage, so disabling C3 and C6 will not help either.  Normally, these should be left enabled for overclocking unless you decide to start doing BCLK overclocking instead of just leaving it at 100.0 MHz.

BSOD after 10 minutes od Blend in Prime95.
I don't want to touch BCLK at the moment so I'll leave C1E and EIST alone smile.gif

Prime95 Blend x45@1.35+PLL is goin on from almost one hour without errors.
