I cant even get 4.2ghz out of my 5820K :(

Goose · 9 Jul 2017 at 16:49

When i first put this system together (see sig) about 6 months or so ago I was getting 4.2ghz with an adaptive voltage setting that game me 1.3v under load. I was still running the original bios and decided to update it since there had been 4 or 5 revisions a couple of months ago. Since i wasn't really gaming any more i never got around to applying my overclock so i've just been running at stock speeds.

I decided to overclock today and for some reason 4.2ghz at 1.3v crashes Realbench in less than 30 minutes. I've never changed any other bios settings because i dont really know what any of them do and my system was always stable so i never felt the need to learn. I dont really know why it's not stable now since the only thing thats changed is bios and that's meant to have made it more stable, not less.

Anyone have any advice?

I just tried 4ghz and Realbench crashed within 60 seconds. Something's very wrong

Kidge · 9 Jul 2017 at 20:52

Have you downloaded something like CPU Z and hw monitor to check the temps and voltages being set?

Goose · 9 Jul 2017 at 22:03

Yup, temps stay below 80c and vcore at 1.3v.

FWIW i've run Aida64 for almost 3 hours and Intel Extreme Tuning Utility stress test for 1 hour and without any BSODs, lock ups, restarts etc.

Maybe Realbench just hates my computer for some reason?

Burr · 9 Jul 2017 at 22:39

Are you overclocking the uncore? Screenies of the bios could be helpful - AI tweaker section.

EDIT: Maybe try resetting the bios and reconfigure?

I had stability issues in realbench on my 5820K at stock. So I just ignored realbench and tested with x264 and x265 encoding as that is almost certainly the most stressful thing I'll ever do with my system.

Nope, not overclocking the uncore and i've tried a bios reset a couple of times.

It's always the same thing with Realbench, I get a dialogue box saying LuxMark has stopped responding. The system doesn't BSOD or lock up or turn off/restart and Realbench keeps on going with 100% CPU usage and i can shut Realbench down and then continue using my computer as if nothing happened. When i ran it just now right before I got the LuxMark has stopped responding message the screen went black for a couple of seconds and then displayed a weird sort graphical corruption for another could have seconds before returning to normal.

Is there any chance it might a graphics issue that's causing this? It wouldn't make a whole lot of sense if it is though since my graphics card is running stock and completes Heaven benchmark fine.

Burr · 10 Jul 2017 at 12:39

From what you've stated here, i'd be inclined to think it's more of a graphics issue. For now disable your CPU OC to eliminate that as a variable and try running realbench again, see if the same thing happens. "displayed a weird sort graphical corruption for another could have seconds before returning to normal." - This doesn't sound promising. I'd recommend running some more GPU intensive tests additional to realbench/luxmark such as 3DMark stress test if you have it.

X99 can be a tricky platform and also not all 5820k's are good clockers, my first 5820k struggled to get over 4.2.

If i were you i would set the bios to defaults and start again.

Don't mess about with XMP or adaptive / offset voltages yet.

Set Overclocking to manual , set the core ratio to 4.2 (to start)

Set the voltage control to manual.

Set a cpu input volage of 1.9v , its a good starting point and you wont need more than that

Set the vcore to 1.275v

Boot into windows , remove any gpu overclock.

Download the latest realbench and run a stress test for at least an hour. If Luxmark still crashes, try running the Aida64 stress test instead.

Report back to base !

5930k user here (so similar)...

I got this exact error in Realbench the other day. Have done some tweaking since so need to revisit and try again.

Not to **** on your chips but my 5930k seems a good one. I can run Aida64 at 4.4Ghz and only 1.23v for about 2 hours before it crashes. Up the volts to 1.25 (under load - I use adaptive volt settings now) and it will go all day.

I wonder if the Realbench test error is GPU related? I'm running SLI 980Ti cards by the way, it's not an SLI issue is it perhaps?

EDIT - just ran Realbench again with my latest overclock settings, as above. It passed the 15 min test which it wouldn't before and I didn't get the LuxMark pop up error thing. Realbench seems far more punishing than Aida64 though - my comp 'froze' a few times for about 15 secs where couldn't move the mouse or anything but then carried on ok. CPU got waaay hot though, up to high 80's on a few cores (one peaked at 89!)

Don't know if this is relevant to you or will help but on my rig the biggest problem I've had with overclocking x99, 5930k is system RAM. I've got Corsair Vengence 3000, CL15 and it just will not run fully system stable at 3000 no matter what I try. I've settled running it at 2666 speed and tight timings instead, and it makes very little difference in the real world / games anyway.

So, I'm no expert but maybe look to your RAM and settings for the issues you're now having...

Goose · 11 Jul 2017 at 16:27

Thanks for the help guys. I decided to make a clean start so I updated the bios to the latest version, did a clean install of windows 10 and then ran real bench with everything at stock and it was fine after 4 hours. It did do one weird thing though. After a few minutes of the stress test the system froze for about 3 minutes before kicking back in to life again. I couldn't sit at my computer for the whole 4 hour test so I don't know if it did it again. Doesn't inspire confidence though.

I'm going to be a bit busy for a few days so further testing will have to wait. I think I'll take it easy and start with 3.8ghz and go from there.

OLDPHART · 12 Jul 2017 at 11:54

Getting a good overclocking CPU is the luck of the draw, try clearing the CMOS see mobo manual.

Nothing wrong with selecting XMP just use your PC as normal, you can stress test all you want and pass but you can still crash in normal use ie: gaming for one.

~>Dg<~ · 12 Jul 2017 at 12:07

use your pc as you would not by what a benchmark prog says.

some 5820k like any cpus are poor clockers some are great.generally the newer ones are generally decent.

you should be able to do your mobo oc so easy its unreal.

just click the auto tune it will ask media or gaming pc then what cooler you have select then it will reboot.then go back in bios go ai tweaker and try whatever multi you want and do what you normally do.thats all on default.that board and them settings should be fine for 4.5-4.6 with a good cpu.all default settings in bios.

Goose · 13 Jul 2017 at 16:20

I just ran Realbench for a couple of hours without issue at 4ghz using the settings below (they still show 3.8ghz from my previous test). The fact it didn't give me the Luxmark error after 10 minutes means i'm going to call this a win. I'll try 4.2ghz when i have some spare time.

Hi

Luxmark is very fussy with apps that monitor graphics. Afterburner is a known culprit. Wager you had it (or something similar) installed before your format and haven't put it back on yet...

If you'd posted a few days ago

After passing 4ghz I installed Afterburner and later ran a test at 4.2ghz that failed. After reading your post I uninstalled Afterburner (just turning it off probably would have enough) and ran the test again and it was still going strong after 3 hours. I know most people dont consider 3 hours a true test but its good enough for me and my light gaming needs.

Ste · 14 Jul 2017 at 17:14

Hehe. In my experience if realbench is good for a couple of hours it's not going to crash. Doesn't mean that the system would cope under e.g. OCCT linpack but if you're happy enough day to day then all good!
