Hi guys i was wondering if some OC specialist could help me with a cause... I want to overclock even further my GTX 560 ti (gigabyte OC edition 900mhz core) so i can get some more FPS in crysis 2.
I Overclocked 9800gt(card before this beast ) and it performed quite well and it was also Gigabyte OC edition so i got some skillz on OC. My question is, Is rising voltage damaging your GPU if so how much and so on... I want to OC this baby to 1GHZ but i'm afraid i'll have to UP the voltage to achieve it (tried it safer way without UPing voltage but i get artefacts :/ )
OVERHEATING is totaly not a problem as with maximum load it doesnt get over 60 degress with 55% on my fan

Sadly overheating will be a problem, your speaking just crazy talk, 1g is 40% above the normal clock, if you manage to even get that stable, your going to surely get that thing running at no less than 95c, for those crazy guys though actually get liquid cooling on thier GPU;s, maybe,but in no way should this OC even be attempted for more than 5 min. on air cooling............ Straight kamakazi run is all it is.

Lets just forget Temperature here... Whats the other downside of increasing GPU voltage??

Well because Nvidia nerfed the VRMs on the 590 and 580 i am not sure what VRMs the 560ti is using. Chances are its the same as the 590/580. If they are if you increase the voltages to high your GPU will explode due to the cheap VRMs. What are the volts now?

uh.....................where do i begin, instabilities, artifacting, screen tearing, plausible ignition, permanent motherboard damage, blown caps, fan grease burns out, instant crashing, GPU dies..................get the picture? Its not something pretty to deal with and is just a quick way of losing a $250 card. First off, you should be worried if your CPU can handle your GPU;s overclock to begin with, or else your just going to have a fan blowing really hard, on a half used GPU.

How can i check that???

what the hell GPUs are you using?! Increasing the voltage will not create instability unless your card is already damaged so that takes artifacting and screen tearing out of the question. The caps on ANY good GPU will not blow unless you exceed some outrageous voltage like 2.00v but msi afterburner doesn't get close to that. And unless he has a quad core are 2ghz, he will be able to hand any OC he brings at his 560.

Ofc thats the thing if u move ur voltage to like 3 volts or 5 volts or something >> im talking about SAFETY ZONE voltage... jesus christ coolguy ur quite paranoic

How can i check that???

I just checked for you. and it looks like they put the same cheap VRMs on that one as well. But as long as you do not do some outrageous overvolting you should be fine. What is the stock voltage on your card?

i just ran MSI kombustor and at GPU info it said VDDC 1.000v so i assume thats 1v stock... btw did u check those VRMs for gigabyte OC card??? maybe they put quality ones??? (whats VRM so i can completely understand u in future )

its the same one. Also you dont have to run Kombuster to find the volts. The top slider should tell you.

Dont be to worried about the cheap VRMs on the 560. the power draw is not HUGE like the 590, so chances are you wont blow it with the volts that Afterburner lets you access.

So back to the question... what are the bad sides for uping the voltage from stock?? can it cause GPU to die faster or something (exclude temperature)

Lol... i just checked in MSI afterburner how much i can increase it and max is like 1.15 volts (1150)

Not really, people don't understand it fully. Upping the voltage on a already perfectly working GPU wont do any harm. (unless you are SUPER overvolting, in which case it doesn't matter if it dies). Just upping volts wont do any harm. Its the HEAT it causes that can reek havoc. But because i am not sure if Gigabyte offers software for upping the wattage of the card you will only be able to hit a certain voltage within the power draw limit. you should be fine within a .15 increase over stock voltages. after that, heat starts to go up very quickly.

so i can up the voltage without worrying that im dmging my GPU(ofc im talking about volts within parameter not like 2 volts or something) unless uber temperature or something which i doubt will be over 65c when i reach 1ghz cus giabytes cooler is beast

One more thing before i venture into OCing for this card... can i use Kombustor for OCing or do i need some stronger benchmark tool?

You should be fine. again like you said within parameters. Just watch your temps and have fun OCing

One more thing before i venture into OCing for this card... can i use Kombustor for OCing or do i need some stronger benchmark tool?

Kombuster is fine. Run it for about 10 minutes if you really want to check stability and heat.

Ok thanks for devoting ur time... Now its time to OC this baby

Ok i got one more question... I have OCed my GPU to:
Core 1000mhz
shader 2000mhz
memory 2004mhz
voltage 1050
i am seeing little bit of artefact like tinny black square pops once in a benchmark screen. Do i have to up the voltage a little more and restart my comp or just to increase voltage until no artefacts?(I don't know if u have to restart ur PC once u start seeing artefacts so thats why im asking).

Artefacts are a VRAM thingy i believe, i'd try vRAM @1900 or something, volts @ 1.1.

Artefacts are a VRAM thingy i believe, i'd try vRAM @1900 or something, volts @ 1.1.
well as i know each of these can cause artefacts... and Vram is stock vram which is @ 2004 even on nvidias gtx 560 ti, gigabyte didnt OC memory so its not memory for sure
Aint 1.1volt a bit high or something??? and do i have to restart comp and up the voltage once i see artefacts or i can just up the voltage until no artefacts?

I warned you and you laughed, so be it.

M8... I know what are the symptoms of too much OCed GPU and im very cosious but the way u described it was like "wow dont OC it for even 1 MHZ or it will explode and make huge explosion like atomic bomb" or atleast thats how it sounded to me. I just need a bit more help to finish my OC process and have stable GPU hope sli or the other guy will answer^^
