Haswell Overclocking Guide [With Statistics] - Page 1818

post #18171 of 19600
from the point of view of OC potential, if I would like to build an ITX OC platform, and of course not now, but maybe in the 2-3 months, I am better staying with haswell line or move to skylake?

If building from the ground up? Skylake.

If you already have a good board or chip, I'd keep Haswell.

No, I have G3258 with a good but still cheapish MSI ITX board, so I am planning to sell that off.
Guess I will go skylake then.

Worth selling to buy skylake i think, especially if you only have one item like a set of RAM. If you don't have anything, easy decision

I'm using Intel XTU stress test for 4 hours. Both 1.27 & 1.28 rebooted around 3 hours in.

I tested with a 1.9 VRIN and 1.20 vring. Temps fluctuate between 78-82C

Are you using XTU to overclock, or are you changing bios settings. Have you tried using any other software for stability checking Realbench, AIDA64, or OCCT?

Edit: X264 is popular for stressing on the Devils Canyon owner thread in my sig.

There's hundreds of thousands of 4770k's out there. That's like only 1/10000 of who have posted there results here. I can hit 4.6 @ 1.35, but I run it 24/7 at 4.5 and 1.310v. I haven't run stressing software lately, but I have a 560, 480, 360, and 240 radiators and my temps stay below 65c while gaming (that's with two Titan X's volt modded).

It is the second day I am trying to beat 4.5 with my G3258, but still I can't get stable configuration. Temperatures are not yet a problem - still on a stock cooler, waiting for the Kraken X31 - I reach 73C under stress, 33C idle.

4.4GHz stable:
Vcore = 1.266
Vring = 1.15
Vin = 1.8

Ring: x 40
RAM:1333
CPU Phase Compensation: 1.2
Voffset 100% (but I guess it does not work with override Vcore settings)
EIST enabled

My mobo supports 1.4V maximum Vcore voltage, but even if go up to 1.35, the CPU is unstable @ 4.5.
What settings would you guys suggest to experiment with in that situation?

PS: theoretically, if the board was to be replaced with one having Z97 chipset, 6 not 4-phases, etc. can I get higher stable frequencies? Or this is more a die issue
PS2:
During stress tests one core is almost always 73C while the second is just 63.. is it bad IHS/core thermalpaste connection or these CPUs just work that way?

update:
When I do passmark CPU test @4.4GHz, I get 3431.9 points. It seems a little bit strange as online comparison charts states an average value for G3258 to be 4001.2 points and that is at stock 3.2GHz speed. What can be a root of this problem? What program is best to compare CPU performance?

cinebenchr15, x264 encoding (the fps score at the end), intel xtu benchmark.

When u run cinebenchr15 be sure to set priority to realtime after opening but before starting the test.

Run cinebenchr15 at stock then compare to overclocked. If the number is not higher you likley are not stable.

Will try that, thanks. I am just lazy as I did not save non-OC profile with other settings wink.gif so I myst now "-" all the voltages to auto wink.gif
