Haswell Overclocking Guide [With Statistics] - Page 220

post #2191 of 19539
A hearty "Thank You" to Darkwizzie and all who have contributed to this discussion. It has been a long time since I did a build or OC. Things have certainly changed a lot since then, and I appreciate all the information available here. It has been an education and fun.

My i7-4770K chip is not a winner. Best it can do is 4.1:

Monitor: HWiNFO64
MB: Asus Z87-PRO
Air cooling
Base clock: 100MHz
CPU mult: 41
Cache mult: 37 max / 8 min
VID: 1.216 (manual)
Vcore: 1.216 (moderate load) - 1.232 (high load)
Memory - 1866MHz
Max core temp (peak workload): 77C
Typical operating core temps: mid 60s - low 70s
Peak package power: 100W
Typical package power: 65-75W range

Some stress was performed with Prime95, though not for long. World Community Grid apps were run 12 hours a day with 8 threads, 100% duty cycle, for several days, without incident. I realize this is not anywhere near Prime95 stress levels. The rig has been stable for my purposes.

C states are enabled; things throttle up and down as needed, quite nicely. No complaints there.

The rig is built principally for Photoshop and sound editing. 4 threads of World Community Grid at 80% duty cycle run in the background. WCG is suspended when I am doing something really intensive.

"Peak workload" is 8 threads of World Community Grid at 100% duty cycle.

I've seen a number of the weird Haswell behaviors reported in the discussion. When the above config was allowed to use adaptive voltage, Vcore would hit 1.312. Trying for 4.2 (with Cache set at 35x and memory at 1600 or 1333) it hits the wall: requiring a VID of 1.259 which gave in a Vcore of 1.280 and temps in the 80+C range. For my taste, this was too high given a 100MHz improvement.

Though I am disappointed that my OC is not high, I am pleased with the overall rig. For my purposes, it is a beast and has been providing much enjoyment (mostly Photoshop.)

I know this little overclock, is very little. And its far from being even a mid-end overclock. But I dont care biggrin.gif
4Ghz on my i5-4670K. I have not tryed to push it any further. I just set it to 4Ghz in BIOS adjusted CPU voltage, and began to test for stability.


Heres what I changed in BIOS:

-Host / PCIe Clock Frequency = 100MHz

-CPU Clock Ratio = 40

-CPU PLL Selection = LCPLL

-Intel Turbo boost = Disabled

-CPU Vcore = 1.08v

-CPU VRIN loadline calibration = Extreme

-PWM Phase Control = High Perf

That was pretty much it. Very easy. Just up the multiplier a few notches and raise the CPU volt. And then result. I kept the uncore at default, since theres no gain in gaming, overclocking it.

Now for stability testing
AIDA64 Extreme Edition:

-Stress CPU = 1 hour alone

-Stress FPU = 1 hour alone

-Stress Cahce = 1 hour alone

All 3 above combined = 8 hours and 15min

ALL PASSED

I'm not sure about temperatures. The FPU test were very brutal, and took the hottest core up to 78c. While the two other tests, max hitted 68c

EDIT: About these here. Should I enable them all again, so the CPU can throttle down in idle mode? But what about the CPU voltage?

-CPU enhanced halt c1e
-C3 support
-C6/C7 state support
-CPU Eist

@Wendigo, overclock speed is subjective and personal, if is what suits your needs all good. We are not exactly dealing with slouch cpu`s lol even at stock clocks. This is a performance site so people push and squeeze every bit of free performance out of their hardware. There is a point of diminishing returns though where cooling costs and minimal performance boosts count themselves out of being worthwhile. If your 4 ghz suits you be happy lol

I am all happy about my 4Ghz overclock. And I think I'll stay at that forever. cheers.gif

But what do I do about the last part of my post above? The part that starts after "EDIT"

Someone will post in that regard, as far as i know the power saving modes being disabled on Haswell have no effect on overclocking or stability. I have all enabled. Nothing is turned off and I idle on a 4.6OC @0.704 vcore and down to 800 clock speed.

Go ahead and enable them all. They won't cause any problems.

So I enabled'em all. And here in idle mode, my CPU still running with 4GHz. What gives?

It is possible to be 2h stable at aida64, and crash in SC blacklist? I even upped my voltage by 0.1 from 2hrs stable in AIDA but is keeps crashing anyway... Or it is game related, not hardware?
