Wht cant overclock the core to+100 mhz on GTX 970 G1 GAMING?

[SHREDDER]

Ι have GTX 970 G1 GAMING and after lot of tests the highest stable overclock i have done is +90 mhz core+ 500 mhz memory. That with +112 power limit. PSU is Corsair 750 M. (750 WATT). But if o verclock the core to +100 mhz or higher it crashes in all games in less than 1 minute. However i have seen many comments on youtube and overclocking forums from people who say they managed to overclock the core at+ 140 mhz with no issues. So why i cant? I bought it on November 2014.

Those people running +100mhz core clock or higher increase the core voltage.

Also the silicon lottery plays a role here.

No i wont do it because it is too dangerous. I thought i could reach 140 mhz with stock voltage. How much of perfomance increase is +140 mhz compared to +90 mhz? Is that so much more fps or it is not worth it?

The reason iam looking into it is because on a pc game forum that iam member they said that in the coming days they will have a competition for a 4k Acer predator 27'' GSYNC monitor, and one of the moderators even told me that they consider ME to win it because iam the best there. Nothing is certain at that point but if i win it then i will need the best perfomance i can until i chagne graphics card that why iam asking it. Right now i have DELLP2416D(24'' 2560X1440 60 HZ IPS 8 MS) and this monitor is a 27'' 4k 60 hz 4 ms ips G SYNC.(if i win it). So i want to be prepared in case i am the lucky ones who gets it!

Only a couple of FPS. 3-5fps at most.

Increasing the core voltrage is perfectly safe, lot's of custom cards run overclocked out of the factory. You can safely add 200mV. (depending on if your card was factory OCed or not, don't go much higher then 1,3v)

Yeah.. the GTX 970 is not a 4k card. You will need a GTX 1080 ti to game at those resolutions.

There are few games that GTX 970 runs at 4k max settings 30 fps like Destiny 2 for example but in most i will have to either run them on high settigns on reduce the resolution to 2560x1440 and continue playing them max settings like iam doign now wit the 1440p monitor that i have. But all games look worse on 4k at medium or high settings compared to ultra settings 1440p, right?

[FeilDOW]

Depends on personal preference most games are hard to tell settings from high and very high/ultra so high on a 4k monitor was the route I went over my 1440p 110hz when I ran my CF 290x.

If your 970 is factory OC'ed it won't OC as far as someone that has a FE or non OC'ed edition card.

GTX 970 was never a 4K card anyways. Unless you play PES or something. Sticking with 1440p ultra would be better for your case. If you win that competiton and get 4K monitor just do yourself a favor and purchase a 1080Ti.
Also increasing voltage is not dangerous and can help you achieving higher clocks.

Ι hope that i will win it anyway. I already did upgrade my pc on march when motherboard burned and i forcedto buy new cpu ram and motherboard. I wasnt planning to upgrade anything this year until that happend so i did it because i was forced too. If GTX 970 dont burns too suddenly like motherboard did then i will also not change it now because there is no need yet.

Also what about 4k movies and tv series episodes? Will they run ok with 970? I already tested some and they run well(however they run at 1440p since i have 1440p monitor now).

Yes 4k video will run fine on a GTX 970. You can watch 4k movies on a Intel HD nowadays.

Yeah movies and videos will be totally fine on 970. Also if you are concerned about temps you can either increase fan speed or replace the thermal paste of it with better one.

To be fair I wouldn't class a 970 as enough for 1440p either, infact, it was the reason I bought a second 980 to sli as I want getting a high enough frame rate at 1440p, but I guess FPS is very subjective when it comes to what is good enough.
As for overclocks, it's down to silicon lottery I am afraid. I won with my zotac 980 amp extremes with them both clocking above 1530MHz, and with my wide selection of 1080ti's I had winners and losers (I've had 7 due to faults lol) with the worse failing to hit stock and sitting around 1560, one that would barely boost to 1800MHz to the winner who hit 2150!!!, Sadly, it had faulty memory so had to be RMA'd :( the current pair sit around 2025-2050MHz before heat slows them them down, which should be fixed now they have waterblocks fitted hehe.

So yeah, luck plays a big role in your over clocks, my 980s got me to the top 100 on 3d mark, my 1080's are no where near :*(

I just got my first crash! I was playing mortal kombat 10 and i was close to win !(online) then suddenly monitor became black and then i got a error message who said your video card or drivers are not supported, Then the card reset back to normal. It has been 2 days that it was working ok with that overclock until now that happend. Why? Didnt have any problems for 2 days and now suddenly this is happend... What should i do? Live it back on default clocks?

Increase the voltage or clock the card down a bit.

Memory is more important than Core
And you never want to do Core all that much anyway. 80ish or so should be plenty.

And getting a display driver crash means the OC isnt stable, some games are more sensitive to such things than others.
