Post your GTX 980 TI Overclock Results

evilsofa said:
I think I've finally got things sorted out and established a baseline. My 980 Ti Hybird (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.

Or a cooler that is only good enough when it sounds like a jet.
Or a cooler that wont be good enough even maxed out.
Or a bios that limits the card.

His statement is about high end air cooling.
1500MHz should be attainable with a modded bios. But he does not state at a usable sound level.
This is not the same as most cards on sale being able to reach 1500MHz out of the box and it being a usable overclock.

1600MHz isnt a high end overclock, its a Uber overclock.
Rare.


Despite being told that ASIC does not guarantee a chips behaviour, you are still insisting it does.
There are too many exceptions for it to be a hard standard.
Looks like you found one.

I hear ya man about the BIOS things.It should make people nervous like ten years ago.I kid LOL.
Today cards are easy to flash and I have done hundreds of flashes in the say the last few months.

Great price on the 780 and I hope you do get what you want when it's time to sell 980Ti.

Computer specs its and old 4 year old CPU 3770K@ 4500mhz and 980Ti nothing special.

Anyway I did up a quick flashing guide and it is the same as many others out there if you ever want to try.

**FLASH AT YOUR OWN RISK**

**IMPORTANT NOTE**
You can learn about making BIOS for your card in this forum link(NVIDIA). Just do lots of reading.

All the tools need to edit and flash your BIOS.Always make backup of BIOS with GPU-Z.
I could even make a BIOS for ya .

Tools Included in download.(For ease of use all files in this quick guide will go on desktop,including any save and modded BIOS)
MaxwellBiosTweaker.exe
nvflash.exe
nvflsh32.sys
nvflsh64.sys
GPU-Z.0.8.6.exe

Tools

Flash guide:980 Ti for single or more than one card for SLI

1.Unpack/unzip folder to the desktop.(Folder name :NVFlash_980ti)I picked desktop.Just because you have to change directory of files when flashing your card hence(CD C:\Users\yourname\Desktop\NVFlash_980ti)
2.Back up your BIOS with GPU-Z
3.Open backup saved BIOS with MaxwellBiosTweaker.exe
4.See voltage table section below and set voltge the same.(After you saved new BIOS you are ready to flash your card)
5.Run Command Prompt as an administrator(important)
6.Patse this in command prompt.Change yourname to your computer name (CD C:\Users\yourname\Desktop\NVFlash_980ti)(CD=Change Directory of the path where your files are C:\Users\yourname\Desktop\NVFlash_980ti)
7a.To flash one card or more(SLI) paste this in command prompt (nvflash -6 BIOSNAME.rom).[Nvflash will Flash all BIOS to all the 980TI cards with the same ID's] (BIOSNAME.rom) will be whatever name you gave your new bios.
7b.If you have more than one card and want to flash a specific one:
Type in command prompt - nvflash --list
Look at the index number (0, 1, 2, 3) and then
nvflash -6 --index <#> BIOSNAME.rom
8.Follow on screen prompts.
9.For best results restart computer when finshed and reinstall new drivers which would be the best.(Although new drivers are not needed,just a restart of computer needed.

With that 3770K clocked as it is and your 980 Ti, as long as your PSU is high end and you're running SSD you'll be good for another year at least!

So, I talked to my tech guy, who does all my CPU/heatsink installs & driver magic on the mobos so I don't need to reinstall Windows...those sorts of things. Any way, I mentioned modding my GPU's firmware and he just laughed and said: "Nick, suffer with your 1540+MHz for now and sell it when BIG Pascal's released."
I had to agree. He has a test bench that I can bring a 290x or whatever in and do some BIOS modding, you know, get some XP from it. I wouldn't care if I bricked an AMD card any how..lol f*ck 'em. As long as they make an effort to keep NV from goin all monopoly on us, that's good enough. lol
Thanks for the tutorial and I pasted in folder on a thumb drive for when I'll need it!
Hey you got a YT channel?
 
Looking for opinions on my EVGA 980 ti SC+ ACX 2.0.

I am at +100 core, +400 mem, +0mv, 121% power target. I get a constant 1444mhz at around 78-80 degrees in Rise of the Tomb Raider. It clocks at about 1480 until the temp exceeds 75 and then it begins dialing back. I don't recall the exact fan speed % but it's 1800-2000 RPM. ASIC is 83. I'm not at the limits of the OC, but I am at the limit of where I want the temps/fan noise to be.

The first bios I flashed set the voltage to always be 1.28v with a 121% power target. I was able to get a stable 1530 mhz with that that (I think I had +130 core, didn't try higher) but the temps were hitting 84 and the fans were at or near max.

The current bios is stock except it has a 121% limit instead of the default 110%. With the stock bios RotTR was causing the card to downclock into the mid 1370mhz range with "PWR" being the perf cap reason given in GPU-Z.

My case is a Fractal Define S with plenty of airflow, ambient is 23C.

Should I be expecting better temps at my OC and fan speeds?

can you find out what internal case temp is?

Are you sure the fan is 100% at those settings? Those temps do seem high. Your card should get 1550-1600 with that high ASIC...maybe higher.

I get 65-75C on mine but i think my heatsink is a bit better but i have a low ASIC. I use 1.254v and 1500-1550 depending on game.

Are you sure fans are near max? Try forcing 100% fan speed an see what u get.

As I said earlier stick a temp gauge in case. I know my old case woudl get super toasty and i had a few fans in it too. I have a core X9 and internal case temps are like ambient now. This generate a solid amount of heat so your case maybe hot. Try taking side panel off and see if temps drop.

Fans are not near max with my current OC (+100 core, 121% power, +0mv, etc). I'd estimate they are around 60% in game. I will check actual fan % when I get home and try running them at 100% and also try running with the side panel removed. The case exhaust air is never particularly warm.

I have 6 140mm fans. 4 intake, 2 exhaust (including the 140mm AIO rad in the top). I am hoping airflow is not an issue..

ideally the front and bottom should be intake. But yea you seem to have good air flow. IIRC there is a massive difference (at least for mine) between 60% and 100% in actual output of air.

if 100% fan your still above 75-80C in temps and your internal case temp is low than you might have a bad past job and you might want to repast with like ICD or some other high end tim. I like ICD because it lasts forever if done right.

Looks like I may have been too optimistic with my fan curve. I now believe my card is in line with others I've seen posted here.

My current fan curve gives me 77C at 55% fan speed with Unigine on a loop (with the +100 core OC described in my other post).

At 100% fan speed it drops down to 65C.

I fiddled with my OC a bit and settled on this:
Vj300WL.png


2400rpm is about 70% fan speed. It's audible but not super annoying. I'll have to see if I can live with it..
 
whats the voltage you are running for 1500? You probably don't even need 1.25v for 1500 with that ASIC. 1.28v with that asic would get you 1550-1600 I would wager. 83 asic is really damn good.

According to precisionx its 1.193v for 1500. I put the balls out BIOS back on briefly and tried going in the 1550-1600 range but uningine would crash almost immediately.

I am not currently running 1.28v. Last night I flashed the "max air" bios from here, which puts the card constantly at 1.255v. With that, I tried upping my OC to 1550-1600 but it was not stable.

I put back my "stock bios with 121% power target" bios and settled on the OC in my screenshot above. The voltage I'm running at now is around 1.19v
 
1500 at that votlage is solid. surprised u cant get 1550 with slightly higher voltage but 1500 is still good,
 
yea i am at 1552mhz 7600 for ram and 1.254v with 130% power. I have fan at 100% and i am 50-57C while gaming. Total power is 90-107% and i am 50-57C in temp. I do believe gigabyte has a better heatsinka nd fan design than EVGA but those are my settings and temps.
 
EVGA Reference 980Ti (Non SC) in SLi

ASIC 71.1 and 74.7%

  • Power Target: 110%
  • GPU Clock Offset: +198MHz
  • Mem Clock Offset: +400MHz
  • Voltage: +0mV
  • GPU Boost Clock: ~1400MHz

do you mean throttle temp? Its like the 3rd dial that says temp limit or something. Default is 84. Or arwe you asking like custom fan profiles to have variable fan speed based off temps?

As long as your below 84 there isn't a reason to play with it. Your temps seem solid. You got decent ASIC BTW. If you want to OC down the road you might than want to consider custom fan profiles. I just run my fan at 100% when i OC because i wear head phones when i game. It all depends on what you want to accomplish and what temps are acceptable to you. Lower the better but as long as your nut crazy high your good. I heard haswell was more temp sensitive but i dont know what that means. Older GPUs could rock 100-105C for 1-3 years with out issue....bad idea but they were robust. I heard maxwell was not that durable but i have seen 0 proof saying one or the other.

Maxwell doesn't voltage scale worth jack until subzero. With 1.23V I can bench Firestrike Ultra at 1570, and with voltage maxed out at 1.28V I can eek out an additional 10-15 MHz depending on how lucky I am. Whoop-dee-fucking-do.

Pretty much this. I have more luck actually NOT adding extra voltage when stepping up my GPU cores. For me at least, adding more than 50mv tends to actually start decreasing stability at higher core speeds, and I'm watercooled... GPU's never go above 35C under load, with voltage set at 1.212V. The best I can manage (completely stable) is around 1493Mhz on the GPU cores regardless. More than a 50mv bump just tends to destabilize them.

voltage according to kingpin stops being useful around 1.25-1.3v. Any higher is fruitless unless at sub zero. Some people see no benefit at 1.25v and some see a benefit til 1.3v but any hire actually makes it worse....usually.

I have see a large benefit with 1.254v. I would try 1.3v but i am too lazy to mod BIOS.

Unless you have a HOF, Lightning, Classy, or Kingpin card, you're not gonna go above 1.28V period since the default voltage controller has a hard cap.

Besides, absolutely pointless going above 1.3V (actually IIRC Kingpin said 1.2-1.25V) for Maxwell unless you're doing LN2 benching. Going from stock 1.18V to maxing out at 1.28V I can get an extra 60MHz on the core I think?

i explicitly remember him being quoted that air/water stopped showing return on voltages at 1.25-1.3v and not 1.2-1.25v. I can't find the quote at the moment but i know he said that. Again most of the time 1.25v was make but some cards were still seeing a small boost at 1.3V. It was quoted on most tech blogs. I cant find it now so whatever. Its late and i aint going to go dig for it.
 
Kingpin has made a few posts at various forums, this is one of them (one of the most detailed too) he made over at OCN. I'll just quote the relevant bit:

How does ASIC relate to Maxwell Air overclocking? With maxwell gpus the above definitions of ASIC do not apply Well you guys know maxwell 980,980ti, titanx have ambient cooling voltage limit on what v's you can give it on air/water. That's just the way it is. Its been proven over and over on every single manuf brand 980,titanx, 980ti. kp980 owners as well, no different. These gpus don't like voltage on air over 1.22-1.23v usually max. Just green garbage all over the screen with more, no better clocks. Best clocks usually achieved with stock voltage or maybe slightly higher.

You said without issue. It has to be useable or there is no point.
I can use 1.254V without artefacts but I have to reduce the overclock to prevent crashes.
Less voltage is more for most, unlike your statement.

n=1 was saying over 1.23v there was reports of green artifacts all over. I was just saying i have never seen anyone actually have that issue.

So you loose stability at 1.254v? Your the first one on here to report that.

I have read all 550 posts in this thread and you are the first to report 1.254V making you loose MHz/crash
 
Technically it was Kingpin himself who said that, I simply did a copy pasta. :p

As for me personally, I have found that with both the 970 and 980 Ti, there seemed to be certain voltages that were particularly prone to instability. For example if I could run say 1500/8000 at 1.23V, then for whatever reason if I bump up to 1.25V it becomes unstable, but if I go further to 1.28V it's fully stable again.

You didnt "just" say that, you said most people here have no problem with 1.254V when you have no real clue, and that I had to prove other people were getting "green shit" when it was something you brought to the conversation.
It isnt the only proof of instability.

And?
Most people wont be able to use 1.254V because the bios limits them.
And not all those that can use it will get a better result so wont report it.

Prove that most people here can use 1.254V without issue.
 
The other thing I'd like to say about stability, is that unless you loop Heaven for 3 hours at an absolute minimum, you simply cannot claim your OC is stable. In fact StoleMyOwnCar reported that his overclocks started crashing Heaven after about 8-10 hours in. So depending on how the posters in this thread tested their stability, their "stable OC" may in fact not be completely stable.
 
mine are completely stable at 1450-1500 typically and thats 24 hours of F@H and any game or bench i have run for long periods and even furmark to an extent. Game stable is 1500-1570. Saint Row 3 at 4K was stable for hours at 1570 and 1 or 2 other games. most games are stable at 1500 for hours and hours. 1450-1500 is F@H. I have seen once in a while a fold fail at 1500 but its weird 1450 vs 1500 has crazy different PPD. When you over clock from 1350 or whatever to 1450-1500 you go from like 200-300K to 500-600K lawl IIRC. It was something stupid huge.

A lot of games can make 1550 for a few hours if the GPU is acting right. I had like 8-10 hours of NS2 at 4K(90-110% TDP) at 1550 but another day it crashed in like 10 mins :/ 1500 has never crashed for me in I think any game or if it has its so rare i dont even recall. and my card has shit ASIC 68.x%

I do love how stable drivers are now. If a clock does crash you don't even need to reboot :D I can just reset it :D

EDIT: BTW F@H the drivers never crash even at 1550-1600....just folds fail. IIRC I always run 1500 on it unless i plan on not being around for a few days and i'll run 1450 to make sure no folds fail.

prove otherwise. No where on this forum has anyone said they have had an issue with 1.254v or the likes. n=1 is the only person claiming in this entire forum that he looses stability. I can't prove something that doesn't exist. No one besides n=1 has had issues at 1.254v
 
This back and forth needs to stop. "Stable" is such an arbitrary definition that unless everyone does the same stress testing of their GPUs, the claims of an overclock being stable or unstable is completely meaningless. Then there's also the fact that some games just don't stress the GPU as much, and certain overclocks don't show instability until a few hours into the game. For example, I can game at 1550/7800 but I invariably crash around the 3 hour mark in most games I play. Is that a stable overclock? No I wouldn't say so, but to someone who never games more than 2 hours at a time it could look perfectly stable.

Then you gave the example yourself that NS2 @ 4K crashed that one time at 1550, but was fine on other days. Would that be a stable overclock?

And for the record, I did not say I had issues at 1.25V, what I said was I observed certain voltages don't seem to play nice with certain overclocks. I gave an example but I should've made it clear the numbers are for illustrative purposes only, and by no means was the example to be taken as proof of anything.

We know proof doesnt exist which is why you shouldnt make baseless claims.
And I told you I tried 1.25V, it was less stable.

see now your the 2nd person on the thread to claim 1.25v or so was less stable. You keep taking my statements out of context so stop your bs please.

I said several times no one until now has posted that 1.254v or the likes was more unstable. People have done it on this thread and others. I am not going to go hunting through 560 posts because you want to be a lazy insulate (using your belligerent word here) person.

seriously you got personal problems to say i am off base when you are making claims with no proof.

agian i am not wrong. I said no one posted that 1.254v was more unstable. prove it. I can't prove that no one said nothing derp derp. Jesus you got issues.
 
You said only one person made that claim but I also did in post 549.
You are getting everything backassward.

I dont care what you have said unless its proof of what you claimed.
I can quote what you wrote again if you like, its up there for you to read again if you forgot.
If you havent got any proof then shut up about it at least.

Your posting rubbish needs to stop.
