P8Z77-v DELUXE / 3770k will not overclock (yes another one)

[andybrrr]

I have just bought and fitted a P8Z77-V Deluxe (second-hand) board, and a new 3770k which I delidded and fitted a Noctua DH-14 to.

All seems to be running fine at stock frequency, however the only thing that seems to be actually changing when I change it in the BIOS is the vCore, which I currently have set at 1.25v (which of course is overkill at 3.5ghz)

I have updated to the latest firmware (2104) using EZ Flash utility in BIOS. I have tried a multitude of settings, my latest included resetting to default and watching this youtube video :

Which I virtually followed to the letter, aside from only going to 4.4/4.5ghz, and 1.25v, and XMP setting not available in menus (important?)

What am I doing wrong ? I am new to these quad core chips, I used to overclock old Athlon/Celeron chips in my day, and am getting back on the horse.

Any help at all would be appreciated.

Thanks
Andy

So I have solved this by going through the settings again, and I'm not sure which settings I changed but they were fairly basic fundamental ones, must be just different for the newer bios.

I will repost screens of my settings when I get the time.

BTW. I've only done short burns (15min~) on 4.5ghz @ 1.25v which passed at a max temp of 55 deg on one core, and then another short burn at 4.7ghz @ 1.3v and it seems to pass with flying colors at around 65 deg .. this sounds very low compared to what I have been reading up on, which begs the question;

What is the voltage limit of these chips ?

I am already very pleased with the results and will probably just keep it as it stands as my machine is GPU bottlenecking again (GTX780), which was the aim of the exercise. Will do a longer test tomorrow for stability. Played 2 rounds of BF4 no crashing, so thats a good start (only around 70% CPU usage)

edit. I ran into a temporary hitch while benchmarking at 4.7ghz in that the chipset was throttling the CPU to do with voltage demand I assume. I went into a setting in BIOS that had something to do with prolonged duration or some such, I'll be sure to get a screen of those settings also
