Am I doing something wrong?

So I followed a simple youtube GPU OC tutorial and overclocked my G1 gtx 980 ti by 150mhz (or so I thought) core and 450 on memory.

now it bumps into stability issues above this and I had one reset and a hand full of driver crashes just in few mins with heaven 4k ultra 2x AA.

So lots of people stating 200+ overclocks and I thought with a G1 I should be beating this but then I looked at the numbers and it says graphics: 1689 MHz in the corner. Is this actually correct? Do I need to tone down the OC due to this as people seem to be a lot lower, I havent touched voltages just power to 110% mem to +450mhz and core +150mhz..
Can I damage the card with this even though I've not touched the volts and also is this fine so long as it proves stable in a longer test?

Thanks and sorry for being a total noob I only know what I have learned today this is my first go at OCing!

Thanks

Dave

I would trust afterburner. 1499mhz sounds a lot more realistic for a 980 ti. As long as your temps remain in check the overclock will have a negligible impact on the life of your card especially if you are not adding any voltage.

What are you using to overclock? If its msi afterburner i would use the Gpu clock graph in that software to see what speed the core got up to I have heard unigene can be wrong sometimes. If it is stable at 1689mhz thats fantastic, consider yourself lucky.

I think the way Nvidia cards work is what you apply as +core it applies on top of the boost clock, so in Heaven your card is being boosted to whatever thermals allow (GPU Boost 2.0) plus what you have set in the overclocking utility. That might be the discrepancy you're experiencing in the numbers.

As already mentioned though you can double check the figures.

Right I have ran another OC and looked at what afterburn is showing..

I found issues at the same speed so dropped it down a notch and at +145mhz it seemed stable (I may need to go lower to be totally stable)

Afterburn is saying 1499mhz and Heaven is showing 1644mhz.. which is correct? and also does the below look like a stable overclock or will it reduce the life of the card even though I have left voltage along?

Thanks!

Okay well I will go with the OC then :)

Noticed something strange though I keep getting gpu load drops and that is causing the frame rate to drop then come back up (it does it on stock as well as overclock), is this normal? if not what could I do to solve ect?

framerate is generally 60-100 but when the useage drops it goes to like 35-40 and it happens no matter what the clock speed..

Cheers,

Dave

Are you sure thats not loading screens when the dips occur? My Gpu usage graph looks exactly the same in most games where my old FX cpu can keep up with my gpu. If you are sure this is happening in game and you notice fps drops, take a look at the temps of your gpu and cpu when the drops occur there could be some throttling going on if something is getting too hot, but like i said that graph looks perfectly normal to me.
