There's an Asus guide for overclocking Haswell, I think. You might want to search for that. Perhaps look in their forums or those "asus rog (republic of gamers)" forums. | ||

I booted into windows, running tests. | ||

I still don't know asus settings, bios and names very well at all though. I know Gigabyte like the back of my hand, easily spent a hundred hours or two talking about them and messing around in bios/os in the last few months | ||

I'm running 4.3ghz with 1.15 vcore, really awesome. Do I just try setting the multiplier higher until it fails, and then add more vcore? If I increase vcore with 0.05, then how much would you increase uncore with? And would you increase the uncore ration proportionally with the vcore ratio? I'm running 4.3ghz with 1.15 vcore, really awesome. Do I just try setting the multiplier higher until it fails, and then add more vcore? ^Yea. Keep VRIN 0.5 above Vcore if in doubt too, with llc on it. If I increase vcore with 0.05, then how much would you increase uncore with? ^Don't increase vcore that much at once, use smallest amounts you can. Leave uncore at 34x for now and ring/cache volts at 1.1. You gotta stress test properly And would you increase the uncore ration proportionally with the vcore ratio? ^You don't have to clock it as high as the CPU, and it's more difficult to clock to a certain point (like i'm running 4.7 core but getting uncore past 4.4 would be a lot of trouble) Focus on core stability first, see what you can do, what temperatures you have, make sure performance is correct with cinebench 11.5 (and set it above normal or high/realtime priority) and then raise uncore later | ||

Not much else to do aside from adding +0.05 on digital io volts and 1.7 vrin | ||

You running linpack with avx unchecked in OCCT? | ||

Seems like my OC is stable with stress test but streaming games seem to crash it. Is this a problem with OBS, or am I looking at other parts of my computer failing? I have not OC'd anything else, stock on GPU. | ||

Old experiences from Ivy Bridge and Sandy Bridge are probably a bit worthless, but even with that, stress tests were not that good when only running short tests. For me with Ivy Bridge, there were errors that only showed up after 12 hours of prime95 and things like that. Only after I got prime95 to run indefinitely were games running perfectly stable. In hindsight, it was probably a waste of time with the hours of stress tests. | ||

Still crashed when I ran OBS together with SC2. Its not OBS nor SC2's fail cause it crashes in other games too, I even tried 4.2GHz without any luck | ||

If you are going to be streaming, your stress-testing will need to include encoders. It's going to require a bit more conservative clock then say a game-stable OC :p | ||

EDIT3: The 4.5GHz at 1.25 seemed stable after 2 hours of stress testing, but the moment i load up OBS and try to stream som PayDay 2 it crashed after 5 minutes. I thought stress tests would be way more demanding that streaming. You're confused because linpack/prime don't actually work too well for determining stability, i had to go from ~1.285 to ~1.315 after my ibt(linpack) pic and when i was unstable before, i could pass 48h prime. People are reporting everywhere being able to pass stress tests, but failing in games, and also x264 If you are going to be streaming, your stress-testing will need to include encoders. It's going to require a bit more conservative clock then say a game-stable OC :p Some games aparantly a lot harder on the CPU than linpack. As a basis for stress testing now i think i throw avx off and use linpack for cpu (to see if everything works, i didn't find anything good for determining a final vcore), prime custom blend with 7000MB RAM (lower fft lengh if i want to short test, like 1 min if i'm gonna leave it an hour or 10 min for overnight) for RAM stability (didn't try memtest yet, but bad ram settings seem to mess up prime really fast, wasn't sure what to test with) And then, avx toggled back on for real world usage, x264, gaming, benchmarks, etc. For you i'd say either just add a bit of vcore or drop a core multiplier. It's confusing though - if you can pass 2 hours @1.21vcore but still fail at 1.24? I didn't see that happen personally. Did you increase VRIN a little bit again (like 1.7 to 1.75) Only after I got prime95 to run indefinitely were games running perfectly stable. The difference was with ivy, if you could pass all fft lenghs, you were generally good for everything. With haswell, you pass all fft lenghs in a 24 hour test, and then open x264 and fail within 30 seconds | ||

I thought stress tests would be way more demanding that streaming. stress tests test heat tolerance and certain instruction sets that really push CPU load and the stress tests are more demanding than streaming PayDay 2 using OBS, but the difference is that streaming PayDay 2 using OBS probably makes use of more different instruction sets than the stress test I also think using stress tests with AVX is overrated because it does not represent real world at all and is just useful for really pushing core temperatures which helps reveal temperature related overclock issues, but doesn't help reveal issues for real world applications | ||
