I will try your suggestions and report back. I might give x264 a try as well, what about Prime though? I used it with my old Q6600 and it looks like it is still popular, plus it can be less time consuming?

EDIT: How many hours of x264 are enough?
EDIT2: Is this the right one?

Do I need to change any settings before running it?

Tech ARP x264 benchmark hd 5.0.1
Had some problems to get into the homepage, but that's the x264 benchmark i've used

Here it is smile.gif

Hm, didn't i see a vlc link there? Or maybe it's me who gets crazy...

Thanks guys, already running it but no luck so far, crashes after a couple of tests. Will do some more tuning to voltages. Although I find it a bit weird that I could run AIDA64 for 4 hours and this crashes after a few minutes.

It's pretty hard to find a good stability test for Haswell all round i think. Some stuff like avx2 linpack is very hard on vcore demands etc it seems, but it's impractical to run because CPU draws a ton more power than any other max load . Some stuff checks RAM well, some stuff will fail very quickly if you are slightly unstable in one way, yet let pretty major instabilities in other ways slip past etc. x264 and some nonsynthetic stuff has not failed me yet for stability, just needs some awkward feeling around to get a good OC without an end-all type stress test that's practical to run and will catch everything

@starmanwarz

Post your actual settings please.

Try this:
Multi 46
Vcore 1.245 just set 1.255 can reduce later 0.05
Uncore multi 43 lower that to x34
Uncore Vring 1.2 for x34 set 1.15-1.18 should be enough
CPU VRIN Override LLC Extreme high
CPU VRIN Override Voltage 1.85 set 1.87 if not try 1.88 watch x264 time which is better/longer
Memory XMP XMP 1
Memory Multi x 16 or 1600 Mhz

Maybe your Input voltage is too low, the right input (Vrin) voltage is a major key for stability.
Also watch how long you go with each setting (x264) and write each setting down. This helped me a lot to get x264 stability. I achieved x264 stability, can also play Battlefield Multi player for ages, no more crashes with my setting (4.6 Ghz).

Here are all the settings I changed:

Vcore 1.245
Uncore multi 43
Uncore Vring 1.2
CPU VRIN Override LLC Extreme
CPU VRIN Override Voltage 1.85
Memory XMP
C1E, C3, C6/C7 Disabled
EIST Enabled

Run AIDA64 with the above settings but 1.24 Vcore, crashed after 80 minutes.
Run AIDA64 with the above exact settings, crashed after 4 hours 10 minutes

Maybe if I add 0.005v to Vcore (for a total of 1.25v) then it should be ok. Or do I have to tweak other settings/voltages? How can I say which voltage needs to be raised?

I feel like I am pretty close to stabilizing it, just need like another day of testing.

Regarding temps, I never saw them go above 74, they were averaging high 60's/low 70's, max temps were 81-83 across all cores, they must have spiked like once or so.

Looks like I have a decent chip, what would you advice me to do? Leave it as it is, do some more tuning for an even more stable 4.6Ghz or push further? And something last, bus is set to 100Mhz but CPUZ shows it's like 99.70 and that drops the frequency to 4589 instead of 4600, how can I make this a round number?

Thanks in advance.

Leave your settings the way they are, but increase the VRIN Override voltage to 1.90 - 1.910 and see if that helps out. I'm running the same CPU multi (x46) and cache/uncore multi (x44) as you....

^you're also running 0.1 vcore more than him, so probably different needs for VRIN

assuming VRIN even behaves the same on different chips.. seems to be similar at least. Nobody actually tested that ha

X264 is just depressing lol, tried as high as 1.27 vcore and 1.91 vccin and most times it crashes on 1st run 2nd pass. Stock uncore 1.15 vring. Maybe the chip is not as good as I thought. Still, I will continue testing until I sort this out.

Go to 1.3 on the vcore then....You're not going to be damaging your chip until you start passing 1.5v using air cooling - I'm running mine at 1.35vcore and 1.33 on the uncore, and have been for over a week now. Now it's time for messing with my RAM....thumb.gif

You will only sort this out if you test each setting incrementally. Took me about 30 runs to get x46 with low vcore stable.
Your chip is ca 1,25-28@4.6 Ghz it will need less Input then 1,35 vcore for 4.6. This is only logical. And I can only repeat myself, you need right vrin and my Cpu also wanted right Vring or it would crash in x264.
Good Luck

I see you have UD4H like me, when you experience weird results set bios back to defaults and then enter oc values.
Did this and guess what: suddenly x264 stable. I know this because I tested same setting before and it would crash.
So worth trying, and sure helped me.
