I know these "restart" questions have been asked 5 million times, but I'm struggling big time with it. Thank you for any help.


  • i5 3570K
    Asus Sabertooth Z77
    Asus Titan
    Corsair 1050w Gold
    Corsair Vengeance 16GB CML16GX3M2A1866C10 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820233399&Tpk=CML16GX3M2A1866C10&IsVirtualParent=1)

I first chased down an audio driver conflict.... better now, but still restarting. I rolled back overclocking. Memtest86 ran for 6 hours with no problems. I did notice that this particular RAM model is not supported by Asus (http://dlcdnet.asus.com/pub/ASUS/mb/LGA1155/SABERTOOTH_Z77/SABERTOOTH-Z77-Memory-QVL.pdf).

I'm wondering if I should spend the money on different RAM now? Or is something up between my PSU and Graphics Card?


CPUID Test with Prime95 with mild overclock
CPU:
low = 29 degrees
max = 80 degrees

GPU:
low = 33 degrees
max = 87 degrees (typical with a game)

Other temps don't change under testing except TMPIN3:
low = 24 degrees
max = 62 degrees

Voltages
CPU VCORE 1.088 to 1.312
VIN1 1.008 to 1.016
AVCC & 3VCC 3.312
VIN4 1.008
VIN6 1.488

GTX Titan is on VIN0 at 0.875 V

Thats getting quite warm for the titan isn't it? I believe 105 C is hard shutdown and 95 is the highest it can be set if i'm not mistaken? Do you have good airflow to the titan? Also what kind of cooler is on the cpu I realize its not the highest it can go but that is getting toasty. My i7 920 at a stock 2.66 I have running at 3.8 barely goes over 70 C at max load with prime 95. Perhaps check the orientation of case fans.

The Corsair H100i is cooling the CPU. I just checked the airflow to the Titan again and it seems fine. I also ran a series of games and couldn't break 81 degrees this evening. After about 2 hours I got a restart while I was watching things like a hawk. Checked temps and voltages every 5-10 minutes. Nothing out of the usual. Nothing spiking either. Max CPU temp hit 73 degrees.

However, it looks like Diablo 3 is ~2 hours till restart. Sim City 5 restarts the computer in ~15 minutes. Both are played on 3 monitor surround at 5760 x 1080. Sim City 5 goes about 20 minutes on just a single monitor before a restart occurs. Other than games I can't get the system to restart.

Ok because i'm running the older corsair h100 and I was under the impression that mine should run hotter than your newer i5. I believe the tdp on mine is like 130 while yours on the smaller die is like 77W. Mind you I suppose ambient temp in the room is probably different i'm in a basement and its still -10 C Outdoors here :). But still i'd think your corsair should be able to hold up a bit better than that. I'm only using 2 fans noctua nf-f12 to push air out the top. Before I was using these fans i had nf-p12's in and it made a 10 degree C difference between them in idle and load temps. While I realize that 80 C isn't over the top I was experiencing the odd bsod before and now I get nothing. If you think it may be ram try loosening your timings a bit or drop a little more voltage in there provided you don't have them all the way up now. I run my 1.35 corsair ram at around 1.5 with no ill effects.

I started switching out video cards with an old GTX 285 and a Quadro. Neither had any issues at all. I then gave MSI Afterburner a try on all of them and the only one that caused a restart was the Titan. In fact the Titan crashed 15% of the way through at only 53 degrees on two separate attempts. So, it may not be a cooling issue after all.

Newegg immediately issued a RMA. Only problem is the Titan is out of stock with no ETA. So, I'm beginning to second guess my Titan choice. Thinking I might get some money back and try out a Sapphire 7970 with 6GB. I'm going to take a day or two to decide.

keep your titan you may have just gotten a dud. Mine works great and the temp boost targets are great just set a temp and it overclocks until it hits your max. I'm using it for nvidia surround in 3d on 3x1080p monitors and have no issues running at highest settings in every game. Only one I have to turn down for it to be playable is in crysis 3 which I can still run at highest settings just at medium or lower aa.

SOLVED. On a hunch I decided to test things with a different PSU and it looks like the brand new Corsair 1050w Gold is the culprit. I threw in an old Corsair HX1000 and everything has run as it should under numerous stress tests. I gave it a good 6 hours and all has been well. I even found the system running a good 4 degrees cooler overall.

Best guess: one of the 1050w's PSU rails is faulty and power wasn't being distributed properly. Time for a return on that one after another day of letting the old one run.
