Post your GTX 980 TI Overclock Results

I think I've finally got things sorted out and established a baseline. My 980 Ti Hybrid (ASIC 77.0%) with no BIOS mod is stable at 1522 core clock (+130), 1952 memory clock (+400), 1.2370v (+38), Power Limit 110%regardless of which recent driver I use (361.42, .60 hotfix or .82 hotfix). I can't make the temps go over 53C whatever I do. Stability tested with Firestrike demo and Unigine Heaven.

Long term report: finally played a game that was unstable at these settings. The Vanishing Of Ethan Carter Redux, at 2560x1440 with 372.70 Nvidia drivers, would artifact into a dark yellow screen after about 15 minutes, requiring me to shut it down with Task Manager. I had to back the core clock off to +120 and now it is completely stable. I played at Ultra Quality Preset with TAA, 200% Resolution Scale all night with no problems.

Thought I would leave this here to report a good stability test. Even backing the settings off to High Quality Preset with T+FXAA did not stop the artifacting; only reducing the core clock did.
 
I got a evga SC+ acx 2.0 with a asic of 79.2 cooling is ek titan waterblock and backplate just snagged it off ebay for a sweet deal
On stock voltage 1490 was stable I didn't realize my flash wasn't taking when I reached this so I thought I was already @ 1281mv that's when I realized I must have a special card :cool:

voltage @ 1281mv (gpu-z reads 1.274v)
temps stay at or under 50 with cpu's at full roar sits at around 40 by itself
Reached 1641 but crashed soon after
Seems like 1582 is stable with msi kombustor
haven't touched the ram

Will report back after some more playing with it and actual games tests, I gotta drink a few and watch football (y)

Edit:
Final core speed (with 100% stability)
1481 Base clock
1531 boost for my p00 main gaming profile 1544 seemed slightly unstable after long sessions
1506 boost for my p02 for absolute folding stability it would work higher but would spit errors in log
Now I'm going work the ram up and be back with final results and probably up my firmware for you guys

Hi guys,

After skimming over a few posts in this thread, I'm wondering if I'm having some issues with my card. I just bought it used from a friend. It's an ASUS GTX 980 Ti STRIX D3COC. I played around with overclocking in Afterburner, and the overclocking seemed to go okay besides my temps being a bit high, and consequently, my fan speed at 100% and very loud.... actually I was only getting +50 mV and not +87mV which everyone else seems to have with this card. Anyway, let's get back to noise....

I didn't want to deal with it that loud, so I dropped the OC way down, but temps were still just as high.

I tried ASUS GPU Tweak II, and temps were way better, as was the fan speed/noise, but that software wasn't even letting me OC the memory, and it seemed super bugy, so I decided to go back to Afterburner

I cleared out everything with DDU, and started from scratch with stock clock speeds. In Uningine Heaven, I'm still hitting ~86C with my fan at 100%. Is that normal for stock? Any ideas what is going on?
 
Just picked up a used MSI Golden Edition 980ti for a smokiing good deal :) Cant wait to stick on my spare H55 with an unlocked bios! I will be posting soon.

No it is not normal, sounds like it needs a new thermal paste job.
 
I recently finished a custom water cooled loop with 2 x 980ti MSI Gaming with EK blocks in SLI. What should I expect for a max overclock in SLI using Nvidia surround? With everything set to max in Afterburner, including voltage, I can run in the low 1500s on the core and +500 on the memory. I do see artifacts though once I pass 1500mhz in 3dmark2011 even with memory at stock. High 1400's I don't see any artifacts. Temps are in the high 30s low 40s so that isn't an issue. It passes 3dmark2011 with the artifacts and the score is between 25500-26000. I am using a 4790k with all cores boosting to 4.4.

I read this entire thread but I didn't see any posts about overclocking results in SLI. I probably will settle for somewhere around 1450-1475 for every day use with no additional voltage needed but I am curious what other people have hit in SLI.
 
max software voltage? whats the actual voltage?

Also what are the ASIC ratings. Higher the rating for maxwell the better OC. My rating is 65.7 or something terrible but mine shocking OC decently. if you get 1500 you shoudl be happy. Most people run 8000 on RAM. I run 7500-7800.
 
Max voltage in afterburner. I will check to see what voltage each card is actually hitting.

One card is 76.0 and the second is 71.2 I believe but I need to double check that.

What is the best way to test the ram overclock? Is there any reason not push the ram as far as it can go? The EK waterblcoks cool the ram so temps aren't a concern.

honestly dont know i just know everyone pretty much reaches 7500-8000+

If you get 8000 leave it. It doesnt affect a whole lot IIRC.

If you can get 1500 stable that is very good for SLI. Max software is like 1.254 or something IIRC which is the max that is useful. MAxwell doesn't scale with voltage. At a certain point it starts to get worse unless it is LN2 so max software is fine.

I believe what i am saying is accurate. It has been so long since i messed with overclocking lol Going off memory :D
 
I just checked the ASIC scores again. They are 76.0 and 70.2.

+87mv is the most Afterburner allows. I ran 3dmark2011 and monitored the cards using GPU-Z. The 76.0 card hit 12.050 volts and the 70.2 card hit 1.2370v. Power consumption hit 110.1% on the 76.0 card and 118.3% on the 70.2 card. This was with the core plus 100 and memory plus 500. Max boost was 1493 on the core. I scored 25,757 and saw almost no artifacts. I did see one or two but almost none. If I raise the core to +110 and it boost to 1506 I will see more artifacts. If I push it even further the artifacts increase of course.

So it seems like running them in the 1450-1475 range is where I will end up for daily use. I will keep testing the memory to see where it tops out and then decide where to run it daily,
 
leave TDP at 130% all the time. I have seen my card hit 120-125% a lot in games and in extreme spikes 127-129%...maybe 131% one or twice?

You see dropping for several reasons, TDP, votlage, and because Nvidia just wont let maxwell maintain clocks.

I would just run it at 1493. I run 1500-1550 depending the game and get aritfacts but i dont really care lol.

software voltage stops at like +40 or 50. If you swt +87 it doesn;t do anything. There is a limit and thats 1.254v or 1.245v or something. Look in earlier posts in this thread i have it stated.

looks like you are just shy of 1500 so it is what it is. More voltage won't help.

Now, some people have reported that less votlage works better. Maxwell is a weird arch in terms of OCing. Try backing off the voltage and see if it gets better. A few users have reported that to be the case. 10mv less than max software for some have resulted in less artifacts.

run a static GPU benchmark that is consistent like a moderate load of furmac and keep resetting voltages til you find what the max software is. IIRC its around +40s or something. Once you find that number try 5 and 10 less mv and see if 1500 works and is stable. if not go back to 1493 and call it good. Feel free and still try slightly less voltage to see if you have space to back off.

Less is best but not a big deal.
 
Your right about the voltage. Anything higher than +40mv in afterburner has no effect. +40 and above and the voltage maxes out at 1.237 on the 70.2 ASIC card.

Max power limit is 120% in afterburner so I can't go any higher.

With it set to +40 I get a higher max boost than with it set to 0 with the same core setting. I just passed the Tomb Raider benchmark with the voltage at 40 and core at +125. It was boosting to 1519. I think I saw one artifact but overall it was stable. I tried 3dmark11 at those settings and I saw a ton of artifacts like I always do at the high of a clock speed. With the voltage at stock the max boost is 13mhz lower.

I don't need to push the cards that hard all the time. 1450-1475 for everyday gaming should be more than enough for my 60 hertz triple monitor setup. Most games should be able to stay above 60fps even at stock settings.

Thanks for your help. I will keep tweaking them but I don't want to try a different bios just to reach a max overclock. I am very happy with what I am getting especially in SLI.

If your serious about 980ti overclocking, then a bios edit is in order.

I am not that serious about it. I will play around with the stock bios and be happy with what I get. If I was to mod the bios and get lucky to be 100% stable above 1500mhz how much performance am I really going to gain in SLI? I imagine some but not enough to be worth the effort and risk.

Once strange thing I just had happen is Heaven benchmark does not like Vram overclock. At stock Vram it passes no problem. I tried +500 and +250 and it causes a hard crash and restart. Maybe because I am running Heaven in surround and it is really hammering the Vram?

Edit: I just ran Heaven again at +100 Vram and it passed. For some reason Heaven doesn't like overclocking the Vram much.

I just ran the Firestrike demo with the core boosting to 1506 and Vram at +250. I did see a few artifacts but not many. It passed with a score of 20,599. Not bad considering my processor is a 4790k at 4.4 all cores.

http://www.3dmark.com/fs/11104054

So every benchmark seems to have a few artifacts at 1506. At 1493 I don't see any artifacts. In my opinion that is my highest stable core overclock without modding the bios.

Now I just need to figure out what is the max stable memory overclock is. Maybe I should just leave it at stock and be happy with that.

are you using the right afterburner? The red one? I can set 130% on mine.

The % boost available is determined in the video bios.
It varies for product placement and because there is already boost applied.

TDP boost as far as i know is 100% across the board. If it comes preboosted it will say 110% like my card did. 100% vs 100% is the same across all boards.

I do recall some boards did have more limited vBIOS is that could be true. That mgiht be why i get a higher TDP % and higher votlage via software than him.
 
I have two MSI Gaming cards in case you missed it earlier. I don't know if that is why I can only choose 120% power in Afterburner?

Regardless I haven't hit 120% power usage in any benchmarks. I am already having issues with artifacts above 1500 mhz so the 120% power limit doesn't appear to be holding back my overclock. I won't run with any artifacts for daily gaming. I don't see the point of pushing the cards that hard except for benchmarking and stability testing. I also don't need to since I am running two of them and only have 60hz monitors.

yea 60hz is much easier to run. 1440P 120 hz or 4K 60hz is a bitch :D

I am running three 1920x1200 monitors but only at 60hz. Total pixel count still less than 4k. I am leaning towards an ultrawide for gaming but waiting for the new Predator or a larger ultrawide with gsync. I love the new LG 38" but freesync and only 60hz.
 
I ran Firestrike again but this time at a max boost of 1493 (+100 core/+40 volts) and memory at +200. I actually scored higher, 21,057? The 70.2 asic card only hit 110.4 power at those settings.

http://www.3dmark.com/fs/11105232

Maybe not having any artifacts/errors resulted in a higher score?

Not likely. Just performs better because your voltage settings are more to its liking. Or it's just in the margin of error.

Artifacts are a sign that the efficiency curve has bottomed out on you. You want fast w/o errors as errors mean waste. In afterburner there's a monitor for PL and iirc when you are throttling the PL will go on. Check that and stick it on your OSD to see if you are hitting the limit.
 
Well, finally managed a 1,600 Mhz overclock at +208 Core and +500 on the memory on my 980 Ti Hybrid. Things are pretty good and stable, though I might dial it down to 1,575 on the core for a bit more stability. Temperatures are at 50-55C at 100% load.

Overall the new cooler is terrific and keeping temperatures very stable. I may try and remount for better temperatures but I doubt if it'd improve much from where it is. The high OC at this temperature is pretty good.

What exactly is the calculation for ASIC? I'm at about 84% which I think is good from my understanding?

Sweet card. I found one 980 ti hybrid local seller and got it for $275 but I havent mod the bios so I am at 1500mhz right now and VERY happy with it. My ASIC is very low do like 64 or 69 dont recall now.
 
I've found these cards are really sensitive to temperatures. For instance I can OC memory +300 (+0mV), but if it goes to 62C+ I'll crash. Stay below 60 and there's no problems. This is alongside a +110mhz Core (1515 boost) OC.
 
Furious_Styles said:
Yeah just seems like a really low threshold. I guess that's why the waterblocked/hybrids seem so much better for OCing.
Click to expand...
A slightly lower OC will be ok, its quite normal :)
You may be fortunate to have such a low temp in the first place to find out at that speed.

I know I'm just finding the limits. That isn't so low if I add a few details like that's at 75-80% fan on a lightning. These cards just seem much more temperamental to me. On my 770 lightning OCing was more straightforward. This card I'm throwing around negative voltages and having to tip-toe around rather low temperatures.
 
I have an MSI Armor X2 OC 980ti

Running +130core and +300 memory on stock volts usually sitting at 1145mhz core while gaming. Temps are 78-81*C though. Bought it used and didn't realise the Armor and Gaming had different coolers

turn up the fan. AUTO fan speeds suck. Gigabyte G1 has a really good heatsink and fans so i let it sit on 60% max is 79C but uts always way lower on average Plus 100% fan...annoying without head phones is like 55-65C lol and thats max voltage with 1500mhz
 
on a side note i noticed myt drivers crashing at 1500MHz at 60% fan but put it back to 70% and no more crashes.

Yep. Crank it or go with an AIO cooler!

Use a custom profile WITH 5 to 10 degrees Celsius of hysteresis. Fan speed fluctuations and tone is much more annoying than volume.
 
Hi guys,

I know these are old 980 ti kpe cards but finally got around to water cooling them to see how much more performance i can wring out of them. So far my temps are excellent at 35/39 degrees under 3dmark stress test depending on card. Was wondering what kind of performance I can expect out of them and best way to over clock them?

Thanks

Right now at 975/1430 mhz (boost) at 975 mv/1.025v (boost)
 
Heads up: My MSI 980 Ti bit the dust only a few months outside of warranty. MSI refused to warranty the card :cry:

Ran it with a reasonable overclock and good cooling for 3 years. So much for "Military Class" components...
