Haswell Overclocking Guide [With Statistics] - Page 536

post #5351 of 19539
So it appears that x264 is stable @ 4.2 Ghz w/ 1.225V for a 1/2 hour now, whereas P95 small would fail in minutes. I suppose if no other apps crash (BF4 or Handbrake), it's OK. But it's still a little unsettling because my PC isn't really "stable."

Are there any other non synthetic tests that are more prone to crash than x264?

Ah, ignore me then smile.gif Either way, I'd hardly call using hibernation file as excessive use. There are plenty of examples and "proofs" to show how much data can be written to an SSD on daily basis and that it still lasts years (>10+). You can abuse your SSD as much as you almost want today, only exception would be those useless SF based drives.

Brb downloading it, will run 3-5 tests and report back.

Edit: downloaded it. It says it will automatically do two passes, I assume you do this 3-5 more times?
Another edit: running. It, and it says it will have 4 runs with 2 passes each run.
So far so good on pass 2. Fingers crossed, if works, will try again tommorrow at 1.275, (1.275 failed @4.5 on the synthetic benchmarks that I tried, like IBT,AIDA,PRIME, and who in the f'ing world does that kinda intensity real life?

Thank you for your quick and helpful responses dark, really appreciate them for a new OCer smile.gif

No problem.

Yeah, leaving it on should be fine. Don't forget, the official name of the software is "x264 Bench" so the original purpose was to benchmark the CPU. As a matter of stressing, it has nothing to do with that. Even for benchmarking I think turbo on is fine. We're overclocking our CPUs, it hits turbo all the time on all cores when under load anyways.

 

Don't forget, the first page shows a download to a loop exe for the x264 brought to you by Forceman.

With an SSD, since it's marginally faster than a mechanical drive, and because of the chipset, it doesn't really make a difference. On my Evo, I get 539/415 Seq R/W and 94k/57k Random R/W IOPS with all my C-States on. So performance isn't really affected with ANY C-State on or off.

@Darkwizzie

x264 HD 5.0 is supposed to use 100% of the CPU? Never seems to use less than 96-97% of each core when I'm stressing. I've noticed this quite a few times. As a result, the load temps are only 75C. The previous version I had ( from the main post ) had looping issues so I downloaded another one about 10-20 pages or more ago which doesn't do full CPU usage. Wanted to know if this is normal.

Hmm, you had looping issues with the first one (with Forceman's exe)? What happened?

From my experience x264 doesn't use 100% of the CPU, it's just a task that trips up Haswell a whole lot. The whole "CPU Load" thing is confusing. We have chess, which is 100% all cores, you can barely surf the web with it on, and it's the lowest level stress test you can pick. x264 also lags you to hell but doesn't even use all the CPU. Wut?! And then to top it off, we have Prime, which uses 100% of all cores, and you can safely watch Youtube videos without issue.

 

I would start to question your setup or the legitimacy of x264 if your temps on x264 are lower than that of gaming. Then there's something iffy about that.

Using a Maximus VI Gene too, which just adds to the insult.

8 hours on what? And what batch?

Hmm, you had looping issues with the first one (with Forceman's exe)? What happened?

It would just quit after the first loop completed. Then I had gone a few pages back for a "fixed" batch and an update to the latest renderer.

From my experience x264 doesn't use 100% of the CPU, it's just a task that trips up Haswell a whole lot. The whole "CPU Load" thing is confusing.

I would start to question your setup or the legitimacy of x264 if your temps on x264 are lower than that of gaming. Then there's something iffy about that.

My temps are ~75C with x264 loaded. Probably higher. Load temps while gaming are ~65C on all but one core, which is ~68C. I'll setup a quick bench now, for the hour or so that I'll be out. And then I'll update.

Shan:
What settings? Game? Also, my x264 temps are same as game temps. Are you using a newer version? I'm on 5.0.1 IIRC.

Well, x264 is out! It led me to believe my OC was stable, but I crashed in Handbrake...sort of. wink.gif

Both programs are fine on their own, but adding Firefox browsing in addition to Handbrake will crash or freeze in 10-15 min. x264 + Firefox went for 60 min before I gave up.

So yeah, I'm done w/ stress tests. If it's stable in the programs I use, over time, it's stable IMO.
post #5356 of 19539
Yeah. Left it for an hour. Completed 3 loops. Stats are uploaded as a screenie.



If you don't want to open the image, it's 75C load with x264 at 1.284v with a 1.265VID. Ambients are ~22-23C.

My game temps are usually ~65C or so. Game is CSGO, and I usually have Chrome, foobar, and other stuff running in the background. The game is CPU dependent but I'm quite sure it loads up only a core or two.

Let me guess, you're at stock VRIN?

It would be helpful if you added your Input Voltage (VRIN), Ring voltage(vRING), multi, uncore multi, VID ( and resultant vcore using hwmonitor or hwinfo ).

Maybe you should try setting your RAM to 1333/1600 without XMP and see if this still occurs.

Looking at the front page again, unless I'm simply reading the list wrong, that's not actually a bad batch. Just seems like I ended up with a randomly bad chip.

I know about changing all of the settings you suggested, believe me. I didn't simply try upping the vcore/multi and calling it a day. It's simply one of the worst chips I've seen so far.

XTU. I was initially getting even quicker crashes through Prime and Aida (yes, manual Vcore, not adaptive) and decided to see what I could even get on a less stressful tester before upping the voltage further for stability.

If you were using 1.9 for that low vcore then try less. I'd find the multi you can do with say 1.2vcore, 1.7-1.75vrin and vrin llc, meanwhile 34x uncore (pass 10 loops of x264 with the stress test batch file then game or use system for a few days), and then work up - playing with other voltages like ring a little (using up to 1.15-1.2 while at 34x uncore) and sa/dio maybe even aio etc.

When i'm over my stable OC @1.27vcore, i need io volts manually for solid stability.. it's like jumping into a high end overclock if you just jump to 1.3-1.35vcore, even if the chip is bad so you can't clock high on it. Throwing everything at it probably won't get you anywhere though, or let you understand the chip at all

Reduce to 1.8 with extreme LLC. Some chips, while they're great clockers, may not like a lot of voltage either. And why don't you start with 4.0, then 4.2, then 4.4, and then 4.6? I know these chips don't really have a break in period, but try lower voltages and clockspeeds first. For example, my 4.2Ghz clock is stable at 1.16vcore ( ~1.141VID ) with 3.9Ghz uncore at 1.18v. But requires 1.265VID/1.284 vcore and 1.15v 3.5Ghz uncore to be stable at 4.5Ghz. Huge difference there. All I know is, I've got my winter and my summer settings so far.

Well if he has a gigabyte board, he has to increase the uncore voltage since the stupid auto turbo will do a 40x uncore automatically. What are your settings right now anyway?
