GTX 560 hardlock

post #1 of 19
Thread Starter 
I have it set at 1000/2400 @ 1.15v.
(Max voltage for Afterburner, and MSI has stated that the max of Afterburner is safe and covered under their warranty.)

I ran Kombustor max settings for 15minutes, not a single glitch or anything, with max temp of 57C.

I have also played demanding games for 3+ hours and no hiccups.

I can only get about 1-3 minutes into a Heaven/3DMark11 benchmark and then the monitor shuts off, and will not restart unless a cold boot is done.

An unstable overclock has always crashed the drivers and forced settings into 2D or stock 3D settings, never a cold boot/monitor shutdown.

Perhaps try stock settings? Some games are harder on hardware than others. For instance BC2 allows me to run higher clocks than killing floor, even though killing floor is undoubtedly less graphic-fancy. Last time my cards hard locked like yours was in BC2 (wouldn't last 15 minutes). Ultimately I had to RMA them.

Same thing happens to me when i'm overclocked on heaven. I think it is a driver/afterburner problem. If you try it at stock settings, or turn dx11 off, it should be fine.

EDIT: by the way though, I wouldn't run that high of voltage for long periods of time, the msi 560's don't have heatsinks on the vrm's, and that could easily spell disaster.

When I first received my card, I maxed out the volts for the hell of it. 1.15V gave me hardlocks as well, in OCCT if I remember correctly. I didn't test anything else, as seeing those occurrences scared me.

I've managed 970 core @ 1.025V. Lower volts > small OC's, IMO.

As Behemoth noted, definitely drop those volts down to something more reasonable for everyday use. MSI's warranty might cover it, but I definitely wouldn't want to be without a card during an RMA for an extra couple fps at most; the 30MHz between our OC's won't equate to much, and I manage mine with 125mV less...

Also, how are you managing 57C max at those volts/clocks? Do you have really low ambients?

My ambient is usually 21-23C, 23 being more popular.

How does this card NOT have VRMs cooled? The heat sink literally covers the entire card...

It was my understanding that 1.2v under water was fine, b/c of the lower temps.

I would think 1.15v with 57C max would be fine...

Anyways, I think that its either a driver problem, or the card is bad but I'm not sure which. (There is alot of people with the same problem as me on the nVidia forums.)

Edit: I just ran kombustor max settings for about 12min (I'm sure it would have met the 15min mark) at 1000/2400/1.1v/55C

Do you have a custom fan profile to ramp it up or something? I don't know my ambients here in the dorms, but they seem like a comfy standard room temperature. My load temps in OCCT are definitely higher than that, I'll have to test in a minute.

The voltage is innately safe, but there's obviously something having issues handling it. There's a good chance it's from the lack of VRM cooling.

Check out my sig for proof.

My custom fan profile is:

40% to 45% fan speed until 50C, then 1% per 1C after that.

Maxed temps out at 56C.

Haven't tested a benchmark with the settings yet, it might turn out at 1.15v just produces a hard lock for some reason...

It's not that I don't believe you have the OC, but 56C at 56% fan in Kombustor? Hell, just in BC2 I'm currently seeing 64C at 59%. I'm running OCCT right now and seeing 82C at 77%, auto fan.

I have plenty of airflow in an A1200; I can't speak for whether the 932 is necessarily better, but I can't believe that the difference in cases and our ambients (like I said, I
don't know mine, but it's certainly not warm in this room) can account for like 26C of difference. I must be missing something.

I believe I saw reviews of the GTX 560 at 1.15V, so there's some anomaly keeping us from using it at that voltage.

EDIT: Topped out at 83C at 82% fan.

I agree, 56c seems ridiculously low. I live in an ICE BOX for a room and i'm telling you i thought my temps were great. But at load hitting 56c MAX on stock air just sounds like a stretch to say the least

He isnt using stock air, he has the twin frozr 2, its a beast of an air cooler.
