Hey fellas - Long time no post! I am in need of some help on a new build. The computer keeps freezing on me, sometimes several times a night. It has happened doing various games and I think once with no games going. I have looked in the logs and see a "Kernel-Power, event 41, task category 63 error each time. I just set it up with a clean win10 64bit install, installed some of the drivers for the hardware off MSI's site and a few games and utilities nothing crazy. Some points: I have not over clocked yet Temperatures look fine, even got a new case (TT TheTower 900) Ran windows memory test, came back no errors Ran latest updates from windows PC Build List: 2x Evga 1070 SC in SLI 32 gb DDR4 Cosair Vengance MSI X99A SLI Plus Intel i7-5820K Samsung 950 Pro M.2 256 (OS) Samsung 950 Pro M.2 512 (Games) 2x Samsung 940 Pro 256 SSD 1x Samsung 940 Pro 512 SSD 3x Seagate 3TB in Raid 5 (platter) Evga Supernova 1200 Platinum TT TheTower 900 Oculus Rift + Touch +Xbox 1 controller & dongle Dell U3415W (34" curved ultra wide 4k) Have a cosair k70 RGB keyboard, Steel Series R700, and Razer Firefly Has anyone run into this or know of any possible bugs or next steps for troubleshooting? Any help is appreciated because right now I'm... Things I've done to troubleshoot: Ran memory test with no errors Disconnected all optional hardware, everything runs fine until SLI is enabled with two cards Tested each card out, both work without issue until SLI is enabled Upgraded PSU from 850 to 1200 Platinum evga Disabled audio drivers from Nvidia Adjusted power settings Removed motherboard applications Installed Evga professional SLI bridge At this point I can't think of anything other than the Mobo...Thoughts?
What power supply do you have? That's a lot of hardware, and one of the most common causes of that particular error is a power supply running beyond its limits. Try disconnecting some stuff - one of the GPUs would probably do it - to see if it makes any difference.
If the above doesn't work, I'd try stripping it back to basics - mobo, CPU, RAM, 1 graphics card and 1 drive - and take it from there.
In my experience, that's often [but not always] a sign your PSU is about to kick the bucket. Occasionally it's caused by motherboard power saving measures not kicking in properly or kicking in when they shouldn't so if your motherboard has anything like that, try turning them off.
I should note I have the computer on a large APC unit as well. I did find an article that mentioned what you said too...hmm http://www.tomshardware.com/faq/id-3128570/fix-windows-error-event-kernel-power.html
None that are especially reliable iirc. They tend to be not that accurate and if it is a power problem the system usually keels over before the utility registers or can alert you to a problem.
Ah. I have a lot hooked up, maybe its running out of power then? 4 SSDs 2 M2s 3 HDD 2 1070s Oculus Rift Keyboard, Mouse, Pad (all light up)
Does this info help? since images aren't working for me... http://imgur.com/jJ8Tw6U http://imgur.com/Q4XwnZ5
Was thinking maybe its not enough power... Part Max Power EVGA GeForce GTX 1070 SC GAMING ACX 3.0 170 EVGA GeForce GTX 1070 SC GAMING ACX 3.0 170 Intel Core i7-5820K (3.3GHz/4.3GHz) 339 Drives x9 50 Fans x5 25 Cooler 10 Ram 1.49x8 12 LED strip 2 USB 10 Total of 788 W
I'd go back to basics too.. Update bios, minimum ram, one guy and minimum number of drives you can get away with. Stress test and keep adding till you get to the problem.... Ps that's a mighty pc...
Thanks and I was hoping logs of the errors could tell me without shooting in the dark. My leading suspicion at this time is putting my power usage over 80%. I'll have to check the bios for updates.
Could be the UPS or the power from the wall causing problems rather than the PSU itself. Maybe try without the UPS and in a different socket if you haven't already.
So I updated the BIOS and removed one video card, and all but two drives (m.2 and m.2 in pcie) and so far so good. Will add in a part tomorrow and see if it's still good.
Do you have a power meter so that you can measure power draw at the wall? I'm not convinced insufficient power is your problem as I've run a FAR more power-hungry setup than yours on a 775W PSU without issues... and that's with over clocking and benching, which draws more power than casual gaming or general daily use. If it was me in your situation I'd get a power meter for a few bucks and get a concrete figure for your power draw in a typical usage scenario. For me with two 480s in SLI it was well below 700W, and that was on X58 which absolutely hogs the power.
I have a meter but would need some guidance on how to do this. One of the things I noticed is my PSU is single rail, could that be an issue?
To be honest, I don't think you need to worry about measuring your power. I'm currently running my 5820K at 4.5GHz and I've been crunching 3D renders most of today, and the power draw at the wall for the entire system is sitting at around 220W. There is simply no way in hell that your system is drawing anywhere near the 850W rating of your PSU. I haven't done any heavy gaming with my X99 system but with my X58 system and the 980Ti (heavily overclocked) I was pulling around 440W at the wall during the Firestrike bench. Re. single rail, definitely not a problem - it's actually a hallmark of top quality PSU. If your problem is PSU related then it's due to a fault, not insufficient power. I hope RedFlames is wrong that your PSU could be dying, but it's a possibility.
