980ti not overclocking too well

[Ez2Tan]

I just purchased a Evga 980 Ti hybrid for my rig and installed it today. During the initial OC and starting heaven or witcher 3, I am crashing even at a modest 15% or +171 mhz overclock on the GPU clock. I have raised my power target % to 110 also. The memory was left stock to rule that out. I am reading online that people are able to OC past 1400. My driver is crashing way before that point. I am using EVGA percision X and driver 358.50. Do you guys have any suggestions? I doubt that I could have lost the silicone lottery with a hybrid card.

 

Other PC parts are:

4790k

d14 cooler

16gb of ram 

850 watt PSU EVGA super nova

Sounds you just got a crap overclocker, sorry mate. Try the previous stable version of the driver, that might do something, but if it doesn't... Then that dreaded phrase must be brought up. "You've lost the silicon lottery"

[Lays]

Try 353.62 driver instead after you uninstall 358.50.

Out of curiosity, whats the ASIC %?

64.4%

64.4%

 

That may be why, the only thing I can say is try to keep it cooler, use 353.62 driver, and maybe give it a tiny bit of voltage.

I will be downgrading the driver. Also, the card is cooled with a AIO radiator. Heat wouldn't be the issue, as it stays under 55 during full load.

what is your card actually boosting to before you add +171.. if its boosting to 1350 then you're starting to push your card into the 1500 range(with the 171 offset) where most 980ti's cant reach (it does help that yours is watercooled)

Maxwell likes being cold, anything you can do to reduce load temperature should give you a boost in OC capability.

 

Just because it's below 80C doesn't mean getting lower temps won't provide more mhz

 

 

Also have you checked with GPU-Z "sensor tab" to see how high it's actually going?

[Curufinwe_wins]

Guys... +171 on an evga hybrid 980ti is a 1311 base clock. That's really really high.

My 980ti on air sits at 1292 base clock to reach 1507/1514 boost. (Acutally my 24/7 oc drops to 1280 base to top at 1507).

Like 1300 base clock is literally higher than most reference pcbs would ever be expected to do.

see my comment. The 980ti hybrid starts at 1140 base, so +171 is pretty insane. Another people who clearny doesn't know how gpu boost works.

Also you said you increased power target... Have you touched voltage yet? Finally note again the evga hybrid is using a reference pcb so anything over 1250 base clock should be considered a win. (Jay could only get his stable at 1482 max boost which would correspond to about 1250-1270 base or about +110-130 core clock).

Seeing people with 980 TI KP at 1520~ or so are 1314 base, so maybe he is actually near 1500, only way to tell though is if he opens GPU-Z and clicks that max button

Yea exactly. +171 on that particular card with its stock clocks sounds really agressive.

Or uses msi afterburner like any logical person. (Precision sucks dick. Just saying. But hey probably maybe doesn't matter.)

I like PX because the overlay is easier to read IMO, and K-boost is nice for getting dat max bench score

I like afterburner because support and compatibility is beyond compare and well using lots of different programs (that do the same thing) makes me mad. (I'm the kind of guy that only uses xtu and cinebench for stress testing/benching overclocks because xtu is an amazing hw monitor anyways and cinebench is well epeen.)

[Lethal Seraph]

That's one shitty overclocker. I'd return that in a heartbeat.

Yeah I love XTU, phenomenal program IMO.

Sigh. You literally have no idea what you are talking about. He was trying to do +171 on a evga hybrid. That's 1311 base clock. Which would correspond to about 1520-1529 boost clock (assuming infinite power target and perfect temps, the later being true.) Few aftermarket custom 980tis can hit 1520... On a reference pcb 250W +110% power target? Impossible.

Again at OP anything about 1475 boost clock should be considered quite good considering all the factors going against you (which should be achievable with a mere +130 core overclock according to this review:http://www.gamersnexus.net/hwreviews/1983-evga-gtx-980-ti-hybrid-review-and-benchmarks/Page-2).

Perhaps shitty overclocker in relation to mine esp for performance:dollar ratio. Hybrid's at $730, my HoF 8Pack at $695. Doing 1550mhz on air since I got it.

[Ez2Tan]

Thank very much for the quick information. Sorry, for being the noob on this thread. I was boosting to 1300 ish on no additional OC. The +171 brought me way past 1450 and I barely added +18mV, which lead to the driver crashing. My previous card was the 980 strix OC'ed with GPU tweak. Using GPU tweak seems totally different compared to PX in terms of how the values add together. 

 

Is it strange that I am still unable to achieve at least 1450 with +37mV?

Turn on K-Boost that way its a constant mhz so you can tweak it that way. Also with that ASIC quality try for around 1420 or so and see how it sits then go up by 5 from there. I recommend testing with games as well as benchmarks because I have had cards that dont crash at all during Firestrike and Heaven but fire up a round of BF4 or World of Warcraft and in 10 min they crash. But like I said, turn on K-Boost so you can easily tell your speed. Start at 1420 or so then go up by 5mhz from there. You are good with the voltage being where you have it now. Any other questions, report back to us later and we can help

I have never had a water cooled card before. Would it be wise to increase the voltage since my GPU temperature is low? The ASIC explanation states that higher voltage is better with low ASIC %. I have always stayed away from over volting due to the 80+ Celsius that my previous cards experienced.

 

Also, by the looks of a simple google search, most of the hybrids are getting a 64-65% ASIC score. I guess EVGA is binning out all the low ones and slapping on coolers, what a shame.

A) Bullshit. B) the evga hybrid is a reference card with reference power limits. It isn't comparable to custom cards.

Asic means nothing. Well until you get to extreme asic values and/or extreme cooling.

You still clearly haven't taken a look at max boost clocks which annoys me. It takes no additional effort whatsoever and yet makes the actual level of conversation you have with us significantly better.

The voltage "soft" caps out on the card at 1.224V which is actually less than +87mV over stock so just throw the slider all the way over. In every situation you are going to be power limited overclocking.

Btw the evga hybrid is literally a reference card with a different cooler... Ofc they are lower binned than everything else evga has.

There are literally hundreds of overclocking guides and tutorials on not just the 980ti but also Maxwell in general, so I don't understand how people refuse to actually learn the basics every single one would tell you and then come here and complain about their card having issues.

For the love of god just use msi afterburner...

You don't need to use precision, for the average user there are no benefits to using precision, and arguably you shouldn't even bother trying to learn precision (not that there is anything to learn.)

Finally, at 65% asic and max limits +120 core clock is the absolute minimum I would expect to be stable. This would bring you to 1470 or so boost clock and you can move up from there. (For reference using the same 250W 109% power limit my 67% asic 980ti below hits 1292 base 1507/1514 boost. It downclocks on the power limit sometimes though sadly. It never rides issues with temps or anything else. I'd consider a custom bios but really... 10 Mhz more max isn't a worthwhile investment on a single bios card for the effort.)

No asic helps a bit on maxwell, hence why you see the kingpin's with diff asic qualities having a "stair-step" effect.   High asic usually has a bit lower stock volts, just like CPU stock voltage can be lower on some CPU, giving you slightly more headroom with volts before you hit that ambient-cooling issue with big maxwell on adding volts.

72% is doing around 1520-1540 on air, 74% is doing about 1530-1550, 76% doing close to 1575, 80%+ doing 1570-1600 on air.

The owners club on OCN shows it quite well, Vince backs it up with his findings on his testing as well.

Did you try 1450 without adding voltage first?  

Or did you just assume that you needed to add volts to make up for the core increase?  On lots of 980 ti cards, less voltage is more.  I suggest trying to find your max OC at stock voltage, then try adding volts to see if you get more mhz.

 

Many people I see that OC 980 ti see best results between 1.17v and 1.23v,  only occasionally I see people get improvements past 1.22v or so.

(the evga hybrid bios just like many others limits you to 1.224V max so there isn't likely to be much if any voltage scaling issues, regardless of what +x mV you tell it to apply.)

On the KP pretty much alone are you seeing nice scaling with asic (and even some of there original cards were having issues at first with that but I assume they fixed software issues with that).

Everyone else regardless of asic is very spotty atm (although based on how touchy Maxwell is with power delivery I tend to hypothesis that it is due to vdroop and other power delivery related items more than the binning process).

I would also mention that I have literally never seen/heard a 980ti non-reference be incapable of hitting 1500 core within the 275W envelope (outside of people with awful airflow) and that includes cards as low as 59% asic.

As seeing above 1519 is basically imposible within the 275W power envelope the reference and many non-ultra premium cards are using, ASIC makes next to no difference whatsoever (and particularly in this case).

Overall, when you consider that within the non-ultra premium models 20 Mhz is your 3 sigma variation (corresponding to less than a 1% performance difference) its pretty safe to say you have very small variation.
