BSoD every 5-10 hours. At a loss of what is going on

[Lupy87]

Hi Guys,

I put a new build together a few weeks ago and i thought everything went very smoothly. I managed to overclock my intel core-i7 4930k to 4.6 GHz and primed for a few hours and it was stable if not a bit hot.

I first picked up an issue when i was folding@ home, leaving the pc on overnite, I would wake up with a rebooted system. Prime also produces the same result IF i run it long enough - say 10 hours or more. Tried running at stock frequency but the same thing happens.

Ok, i know diagnosing a BSoD is hard, particularly online and im not sure how to proceed. I will provide my system specs and the error codes.

ASUS Rampage IV Formula Motherboard
Intel Core i7 4930K
G.Skill Ripjaws Z F3-17000CL11Q-16GBZL 16GB (4x4GB) DDR3
2x raid Samsung 840 EVO Series 250GB SSD
Phanteks PH-TC14PE CPU Cooler Black Edition

Vcore was 1.392V when i was overclocking at 4.6Ghz.

BSoD error codes:

The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x0000000000000000, 0x0000000000000002, 0x0000000000000000, 0xfffff8800196e0d2). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 052614-14929-01.

Not always the same code.

Any comments appreciated.

Well, i have been running stable under load for almost 6 days, but without HWinfo64 running. I guess a bit more voltage on the ram and other rails as mentioned above did it. I also changed windows power plan to performance and went into advanced settings and disabled hybrid sleep. Could that be it? Anyway, better stay away from HWinfo64 for now. Running rock solid at 4.5 GHZ now, but speed step is disabled? perhaps that is part of the performance power plan in windows.

Thanks guys.

Hi Lupy87, It sounds like you have solved your BSOD issue but in case you wanted more info there is a handy little tool called BlueScreenView v1.52 you can download it free from nirsofts website it will give you detailed info on any BSOD and help to nail down the exact fault.

Yep, performance power plan sets "minimum processor state" to 100%. Just look for this entry in advanced power plan settings and change it to 10% and speedstep will work as it should again...

Thanks TarifaPirate. :). I didnt know about that tool.

[Lupy87]

Thanks Arne, I did that and speedstep is now working again.

Just measured power consumption out of the wall.

Folding consumes 433W ! Expensive.
Running prime95 returns 355W
Idle is 135W

Folding is way more demanding than most folks realise. Real world usage is the best way to determine if a system is stable, not a artificial stress test.

Folding is a real world pursuit and if you are stable while folding then you are good to go.

I am stable at 4.7GHz now, vcore = 1.36V 🙂

Tried 4.8GHz but needs more than 1.4V

Good stuff! 😄

Thank you for reporting back with your very good progress. Enjoy your system.
