***Haswell -E Owners Thread***

10 hours of XTU cpu test with 4.4ghz and 1.265vcore. Not entirely convinced yet though, how can i be 100% sure it can be stable if i can't test it to the full potential that Prime95 does? Or does it just add more heat and nothing else? Guess i'll run Aida again later.

I'm on a custom Waterloop couldn't get 4.5 on the 5930k at all just crashed with watchdog timeout error
Also need 1.325 volt even for 4.4

Yes that's a poor example for a Haswell-E. You could swap out for a second one or try the 8 core but 8 cores have really shot up in price over last few months.

You probably need around 4 or 5 different overclocking test suites in your tool box to find out what your CPU, Memory and Motherboard can do they all have advantages and disadvantage's. No one suite will do it all unfortunately.

Prime doesn't test anything to it's full potential. The whole reason AVX2.0 calls on more voltage is because of Prime, outside of GIMPS there is no use in being Prime stable, in fact at over 1.3v core on a 5960x you'll just end up degrading it by running Prime.

Fair enough. Managed to get Realbench working, for some reason my graphics drivers weren't properly installed which is odd because i installed them after i did windows. Passed the 8 hours of that, but not all my ram was used because some was being taken by windows.
 
Well that was weird (first time this has happened) :confused:

I fired up Afterburner, and whole PC just froze, with AB stuck on a clock reading of 1030/1250 (my cards defaults), so tried Ctrl+ALT+Del to get up the Task Manager, no go, so hit the restart button on my case, again, a no go, just wouldn't have it, so in the end i held the power button down for the 4 seconds, which worked.

When it fired back up though, it wouldn't boot, just sat on a black screen, so i pressed the reset button again, and again, it wouldn't have it, eventually it did have it and switched off, came back on again by itself, and gave the old Overclocking has failed, press F1 to enter the BIOS blah blah blah.

Went into the BIOS, CPU was reading as i7 5930K @ 3.50GHz speed 3000MHz (which should have been 3500MHz), memory was reading as 2133, even though i was still on my XMP profile 2 for 2800, so just came out of it, not changing anything, just to see if it would boot up ok, it did, so ran CPU-Z, and sure enough, everything was back at defaults, bus speed back to 100 (instead of 127) etc..., so did a restart (from the Start button), but instead of restarting, it switched off, then fired straight back up again by itself, so i went into the BIOS again, and everything was now back to normal, memory back to 2800, CPU speed back @ 3817 (as on XMP profile 2 for memory to give the 2800), so exited without changes and booted up, checked CPU-Z again, and yes, everything had gone back to normal.

Checked in the CCC, and noticed all my settings had gone back to their defaults in there too, so reset them to what i had them at, fired up Afterburner (which worked this time), and ran through Firestrike just to see if it would get through it without a prob, and sure enough it did, alls well again, bizarre!.

ASUS x99 Boards seem to be doing a lot of this. which rev bios are you running.

Hi,

It reverted to 2133 because the UEFI has booted up in safe mode due to failing post. System hangs are normally memory or cache instability. Either way your system isn't stable. Also worth nothing 2800 raises the BCLK to 127 which in turn raises DMI and PCI frequencies, the fact the machine hung when opening AB might potentially suggest your GPU is not happy with the increased bus frequency. This isn't anything uncommon, these buses have a tolerance of around 8mhz, most GPU will kick out at far less. If you continue to experience problems try running the memory at 2750 / 125BCLK.

Ahh Right, well thats the first time its happened since i put it together around the beginning of December, so if it happens again, or i get any other problems, ill try that with the memory.

Thanks guys :)
 
Have people had much luck overclocking the 5820? Just saw a review that suggested they're all speedbinned/dud 5930s and not so good. I would like more cpu power for rendering and i have no interest in SLI so it looked like a good choice.
