Haswell Overclocking Guide [With Statistics] - Page 266

post #2651 of 19539
So in the end, just to get rid of the phantom bsod i went all the way down to 4300 / 4000 - Core/Uncore
However it makes me wonder if it's just simple that my chip is that bad or is my other hardware not enough?

I tought all my things are fairly high end to support overclocks

Is a HX850 enough, is should be right?
It's really been bothering me if it's just been my memory timings that has been limiting me this whole time?

- 2400mhz viper ram
- Seasonic 550w gold psu
- Z87I - Pro
- Kingston hyper x 120gb
- hyper 212 evo
- 4 red led fans.
- 1tb HDD wd blue

You should be fine. You're cutting it very close though. Especially with that overclock. Do you know how much you are pulling right now?

Any who.. I'm trying to oc my 4770k and I can hit 4.4ghz no problem, stress tested and everything (runs a bit hot when stressing..) but one problem that I keep running into is the vcore voltage. It was a manual overclock, and I have the VID set to manual mode @ 1.250v. However when I run a stress test, it jumps to 1.280v at max load, (Prime95 and IntelBT seem to bring this out the most). I disabled SVID Control and EPU Power Saving Mode because I read it was recommended to disable them. Everything else is basically set to auto/enable. Is there a way to keep the vcore stable and not fluctuate like that?

here are my specs:
4770k w/ Megahalems air cooler
ASUS sabertooth z87
16gb Corsair Vengeance pro RAM @ 1600
850w Corsair psu

Stress tests used: Prime95, IntelBT, Intel tuner, Cinebench

Monitor apps: HWMonitor, RealTemp, CPU-Z

Kk, one thing to try is disabling C states, just in case they are enabled. If that doesn't help then it's not too suprising. There have been multiple reports of voltage spiking under intense load. So when Intel put in the integrated voltage controller inside the CPU, it's not to help us overclock more precisely, it was to save power. So... we end up with problems like these.

 

Once you're on adaptive and C states and you're done stressing with synthetics, simply encoding with CPU only will mean a small voltage bump over set max. Small, not too bad.

You are cutting it pretty close with that power supply. I think it will work but don't be too surprised if it doesn't. Overclocking both CPU and GPU will cut it even closer. It is a gold power supply though, that helps. I dunno the power draw of Hawaii cards so I can't comment on that.

Nope.

I know more about mods for Oblivion than the average Oblivion player and there isn't. It just isn't feasible and from what I've seen on Skyrim it's the same thing, there is no mod that allows the game to use more cores. The nearest thing we have that is still relevant (relevant meaning it still helps. At the start, Skyrim had problems with optimization in its coding that could be fixed by a mod, but Bethesda fixed it with their official patch) that doesn't decrease visual quality are stuff like 4gb enabler for Oblivion (not even 100% sure it works, but for Skyrim already patched), few miscellaneous mods but they do not make as large of a difference as being able to use more cores. Their engine by itself is more CPU bound to begin with.

 

Having said that with all my mods for Oblivion/Skyrim, it's now very GPU intensive and GPU is more of the letdown in performance compared to an overclocked 4670k. (7970 ghz edition)

Oh, crysis 3, battlefield 3 and 4. CPU bound games are not rare, and heavily CPU bound games that don't scale well onto multiple cores are far too common. Every game i listed will be limited by the CPU on a single GPU, and not a gk110

Ah yeah, Starcraft 2.

The other games agreed are cpu heavy but again poor coding and old optimisation or bottleneck?? bottleneck is the most over used term on this and any pc forum today. Bf3 uses 6 threads, bf4 rumoured to use 8 and crysis 3 uses 8 just from my play time.

I agree with you on Crysis and BF3. While overclocking may help performance they are not a bottleneck. A bottleneck isn't just taking place if you just found out you'd get higher performance if you overclock the CPU, it means other parts of the system essentially have to wait for the CPU... so GPU isn't being used 100%. It doesn't matter if it's result of poor optimization or good optimization. Crysis and BF3 use quite a bit of the CPU but it's not too bad, it's not a bottleneck.

 

Having said that, even if Crysis and BF3 are not CPU bottlenecked it doesn't mean Starcraft isn't or that you shouldn't overclock as you'd get higher performance for BF3 or Crysis anyways.

 

But something like Enemy Territory with many bots literally prevents the GPU from working at full steam even with SSAA enabled.

Thank you for responding.

Yea I disabled C states, set the CPU Core Voltage to 1.25v, and the vcore stays between 1.264 - 1.28v. So I guess there's no way around that... However when I set C state to auto, I notice that when my system is idle the vcore will sometimes drop all the way down to 0.160v. Is that okay for it to drop that low? seems low to me.

poop. Well glad to hear at least it ain't something I did wrong biggrin.gif
I actually originally thought my chip was bad, but now I can hit 4.6ghz @ 1.24v pretty stable on air. Gonna stress test it overnight and see how it does.

Thanks for the response thumb.gif

I've seen it drop under that on idle. You're fine.

Your chip is above average.

It's normal for it to drop at idle, I've seen mine go under 0.1V before.

If you don't touch the settings, i5 has higher gflops than i7 in that test. HyperThreading and 8 threads on i7 loses against the 4 threads on i5.

For those with Asus boards and running MANUAL voltage....do you guys see your voltage drop way down at idle? This is assuming you have C states enabled. The reason why I ask....I thought manual voltage will fix the voltage, no matter what? I tried manual+Cstates together, and my voltage drops to 0.1vcore at idle....whats up with that? Using HWMonitor

It's a false reading just like the old CPU-Z (1.64 whatever), these chips don't go down to 0.1v, they hover @ 0.7v with adaptive.
