CPU only

it's normal as stress test like LinX & prime95 is more stressful than games.
Games only utilize certain percentage of cores but stress tests will load 100%

did u get BSOD or the PC just shut down itself?
if BSOD, pls refer to 1st post for error code.
if no BSOD, that might be VRM overheating & your BIOS will direct mobo to shut down to avoid burning.

this temp is pretty normal for air cooling when stressing.

First of all, why do u choose Intel board?

Multiplier can only be adjusted down? - downclocking not overclocking
tech specs

conclusion, get a better board out there lots of mobo meant for overclocking

don't worry abt the temps:

sharing your bios settings & PC specs would be helpful

increase vcore
enable internal CPU PLL overvolting

noobs are advised to go thru these OC guides to avoid spoon-feeding.

depends on IMC of the CPU, some might need to increase the VTT to make higher RAM speed stable. Some just don't need to do so.

keep your chip lower than 80C to avoid degradation. H60 is not really a good cooler for stress tests. Custom watercooling is the only way for torture test at such CPU frequency.

i7 is hotter due to the extra threads - HT.
when stressing with Prime95 & LinX, be sure to use the latest version & on Win7 SP1 & stress full amount of RAM available. That's around 10-20C difference between SP1 & non-SP1. Prime95 usually produces less heat/ lower temps than LinX.

Please kindly post up some screenies here. Run at least 20 runs dude. 10 is not gonna enough.

what about try stability test with LinX?
4.8GHz at such vcore is quite nice

Pls refer to Post #1 for stability tool & BSOD code.
OC failure is unlikely a mobo support issue.
Most probably wrong BIOS settings

This thread has exceeded 2500 posts so as per forum policy we need someone to open a new V2 thread.

I will close this thread once V2 is ready. Cheers

57X is a very2 rare chip. The same CPU max out at 56X under water, 2 cores only. 57X is only achievable on subzero. I bought it used for RM2.3k shipped from UK lol. I believe later Ivy Bridge can do better than this & this thread will be dead.

it's really up to you. If you already satisfied with your current setup then don't change. If you want more speed & features from IB & Z77 board then upgrade. But for sure IB has more OC playability since it has higher unlocked multiplier & higher memory limit than SB. Well we'll wait and see soon. Good luck!

Sounds legit as what happened to my last MIVE P67. IME part of bios chip went faulty causing BCLK stuck at 100. But there is no such issue with MIVE-Z (Z68) & RIVE (X79). I hope their Z77 wont be affected too.

That's because speedstep isnt set to off yet
In bios enable EIST (speedstep), C1E, C3/6
In windows, change power management to balanced or power saver.

I always disabled EIST on all of my Intel CPUs. As long as your not putting crazy volts through it then you need not worry about the lifespan, also with regards to power consumption it will use more when disabled but your CPU will probably not be running at 100% load constantly anyway so the power consumption won't be that dramatic. My OC is 24/7 no power saving features, though a lot of the time I am just browsing and listening to music so its not like it's using up tons of electricity as it is.

EIST can be offset by adjusting C1E in RealTemp. Check/tick the C1E box to enable EIST so that your CPU speed wil relax to 1.6GHz or whatever lower during idle. But i dont think you would do this on every reboot.

vCore is reflect to Load Line Calibration (LLC) causing vdroop.
4.3GHz all the time or fluctuating between 4.3-4.7GHz?
maybe you accidentally set the max core temp to 75C in BIOS, so the multi is throttled when it hit 75C.
pls share BIOS settings

weird, since you have set back to default settings, EIST, C1E, C3/C6 is supposed to be enabled/auto. Just make sure that:
In bios enable EIST (speedstep), C1E, C3/6
In windows, change power management to balanced or power saver.
Other than that I really have no idea already. Maybe other forumers got idea
