Hey need some help!
So I was pushing my msi gtx 560ti to get the last bit of fps in bf3 beta.
I was having trouble getting pass 950mhz core clock so I got pissed and bumped the
Voltage to 1.10 and after running furmark for 10sec~ the power just went off and would not power up again.
Do anyone have any idea what is the problem.
I tried another power cable to make sure it wasn't a burnt fuse.
Here is my spec
I5-2500k@4.2ghz
P8P67
Msi twin frozr ii gtx560ti
Corsair gs600 600W
8gb random corsair ddr3-1333 ram
I am aware the graphics card might be dead as well but usually you should be able power up at least so that is not gpu issues as far as I know.
I read something about clearing the CMOS but I think that only applies to have power but no POST can someone confirm.
I think it might be psu or motherboard but is it possible to kill your psu/motherboard by overclocking the gpu.
Also I hear that voltage at 1.1 should be pretty safe for a gtx560ti ESP with the good cooling of msi.
Sorry for the bad puncuation, typing on iPhone.

Did you have updated, non-beta drivers? I think there was an issue a little while back with slightly older ones

Drivers have nothing to do with computer not powering.
I got the latest beta driver which was for battlefield 3 anyway.

Eh definitely seems to me that your PSU died, which is strange because your PSU should be able to support that. Also some GTX 560 Tis won't be able to survive 1.1voltage because you could just have a weaker model as it's totally luck-based, but even so the computer should power up. Do you have something with which you can test your PSU?

Where did you hear that?

Took reference from some overclockers from OCN and http://www.evga.com/forums/tm.aspx?m=981873&mpage=1
And yeah it could be unstable but there's people running a stable machine out there with similar or higher voltage.
|
I may be completely off on this, but
+ Show Spoiler +When I had an unstable OC that crashed my PC like that (without VCore change, though) I had to switch the PSU off and then back on (PC would not boot otherwise after the crash)
I don't know if unplugging it as you did ought to have the same effect - maybe not, since those capacitors hold power for a while and maybe the on/off has some other effect.

if the computer flat out does not turn on, then the problem is very likely your PSU. can also try looking at the power button or the pins that connect the power button to the mobo, but I doubt they are the source of the problem.
also regarding the 1.1 voltage, I have no idea what the default voltage Nvidia uses for the 560 Ti, but just because someone else or other people are able to OC their video card with 1.1V or higher, does not mean that your video card can handle 1.1V.
when you run furmark, not only are you taxing the GPU, you are also taxing the PSU's 12V rail that is supplying power to the video card. so yes, overclocking a GPU can potentially screw up a PSU.
|
Turn the PSU hard off using the switch, press and hold down the power button, wait 5 minutes and turn the PSU back on and see if it'll work.
|
If you fried the VRM (voltage regulator module) on the graphics card, which is quite likely when overclocking that hard, it can short out the 12V rail and prevent the PSU from powering up.
It's easy enough to tell whether the PSU has failed. Remove graphics card, remove mains power for a bit (PSUs often latch off on a short), replace mains power, try to power up PC.
Edit: terminology correction.
|
Yeah still not able to power up my computer, I don't have another psu lying around I guess I'll have to get a new one to really tell if the psu is dead or not.

There was a bug in one driver that caused overclocked nvidia cards to fail in some way without safety measures kicking in, there was youtube vids of sparks flying off cards etc during benchmarks. It doesnt have to do with systems failing to boot after crashing?

You can easily test the PSU with a multimeter. It is safe to do provided you can follow step by step checks.
Avoid over clocking, in reality it is almost never worth it, not only do you run the chance of doing what you did, but you shorten the lifespan of the items being OCed. There is a reason CPUs, GPUs, memory and everything else is at a high point, that high point IS the safe high point....

That makes sense, but it was the latest driver, don't know if have been fixed or not.

I don't have any equipment which allow me to check for any faults at the moment.
Its definitely worth it to overclock your components and its generally pretty safe to do so, it will last enough time before its replaced with newer more up to date stuffs anyway.
Ofc this doesn't apply to idiots overvolting their stuffs aggressively.

It was a beta driver...
Overclocking CPU's is great, with good cooling you can safely get massive overclocks... but all of the factory overclocked GPU's have low margins like 6-8% overclocks at the very most, and some have reliability issues even at that, it isnt worth messing around with GPU's especially with the lowered lifespan

You can clear CMOS with the power off, atleast on my mobo, have you atleast tried it? there should be a button on the back of your tower, a tiny little thing, you'll need a pen to click it.

Just some updates.
I bought a new power supply today and the computer seems to be responding now, though I am still unable to boot if I have both 6pin power cable plugged into my GTX560, it flashes the DRAM_LED MEMOK light + fans goes on for 0.25seconds and then proceed to die again.
If I only have 1 6pin cable plugged in, the computer boot up like normal (but no display). It really looks like the GPU have died as well.
Is it possible to get away with a RMA on a overclocked graphics card? I know that if its OC'd using afterburner etc, it will not be flashed onto the card so they shouldn't know exactly. (ofcourse they can look at how the card was damaged though).
Is it possible to get graphics cards repaired or the only way is to return it through RMA?

How are they going to know it was overvolted? Just tell em it didn't work one morning. Don't tell them you changed the PSU either. Just give them minimum information. It wouldn't boot one morning.
But yeah, go for RMA. Oh, and for the record, listening to people on forums without independent verification can be risky, including this one. Also, going big overvolts all at once is always stupid on any piece of hardware.

I was planning to say artifacts started appearing while playing games (no mentioning of OC) and decided to try some benchmark/stability test and it blacked out completely.
Yeah I understand, I've went up to 1075 without much problem so I thought I could bump it up to 1100 but I guess it wasnt too clever to do so.
