GTX980 Ti G1 Overclocking

[dsr07mm]

Asic 74.6%, Samsung memory

I tried stock on 1080p it's amazing, although as always I wanna find max stable 24/7 clock for my card. I tried adding +100mhz on core while +87mV and +110 Power Limit and it looked pretty okayish. I got +6fps in Heaven and +9fps in Valley. In Firestrike I got better result (over 20k gpu score) but my card was throttlign from 1503mhz core all the way to 1468mhz in Firestrike.

What can I do about that ? It's EVGA SuperPower 850w G2 PSU so that shouldn't be a problem I guess. Am I that unlucky ?

Even with a handful of degrees to spare, I don't think I've ever run Firestrike at my max turbo that I consistently hit everywhere else.

Honestly 1500Mhz is on the upper end of average for Maxwell. What temperatures are you hitting? If you download GPU-z there should be a tab in monitoring called perfcap. It will tell you why your card is dropping a couple boost bins.

My temp is 60c, 61c max.. I have really aggressive fan curve since 970. Once when it hits 60c they are on 70% and temp is not going up. So temp isn't a issue there.

It's probably a power limit then. Honestly anywhere near 1500 isn't bad, but if you really want to know GPU-z is the best imo.

Ok then I have one clear question.

Since I'm doing +139 on power limit (thats the number yes), and I'm not touching voltage (in any case there is throttling), at the moment I have

Core Voltage - 0
Power Limit - 139
Core Clock - +120
Memory Clock - +300

Temp is going between 60 and 64 in Valley and Heaven since I reduced my aggresive fan.

Heaven 101.7fps (+9.6fps comparing to stock)

Valley 103.5fps (+11fps comparing to stock)

The only problem which I have here is that my core clock from 1500mhz drops to 1486mhz during those benchmarks at one point. Should I leave and ignore that ? I mean overall result is there, can that harm my gpu in any way ? Other then that this looks solid to me.

Going above 62-63c can cause minor "throttling" with maxwell, because that was apparenly a good idea. I drop to 1486Mhz from 1495Mhz at 63c.

Throttling is completely normal. It's not a sign of anything wrong with your PC

Ok I will leave this clock then since I'm getting much higher fps in benchmarks.
