GTX 980 Ti low core clocks, low temps

Its seems its not as easy as trying a custom bios. You have to copy settings from one to yours using the maxwell 2 bios tweaker then flash it. There are many different settings and not s great deal of info on most - there is some info though.
Might give it a try tonight. Memory overclock to +640 gives an extra 5fps in all GTA V benchmarks
 
Hi, have you already tried to to clean out all driver with a third party tool like driver fusion or DDU? Then download one of the actually driver again and install this. If there are reg entrys from older cards this can affect clocking of the card. The Precision version is also a rather old one, most actually one is 5.3.10 I would suggest to clean this also and download one of the latest versions http://www.evga.com/precision/. Can you let us know which power supply you are running and the other hardware in the system? Which temps is your CPU and mobo running at? Did you already try the OC BIOS with higher targets? When you enable Overvoltage and Kboost in Precision you get access up to 1.3V. Can you try if the card accept any voltage up to 1.25? Cards can downclock at certain steps but should always stay above the boost clock till they hit the set temp limit. Did you OC RAM and Core at the same time or have you done this seperate? If not please try to leave the RAM stock and see if this will change GPU OC.

Hmm that's a lot of extra memory speed for a minimal gain in this case. Having never flashed a BIOS I thought I'd be easier - my bad. Still, are you happy with the card?

Its a fast card by default but I paid premium for a classified card to be able to overclock it. When it cant even hold 1200mV with an aggressive fan curve im sure something must be wrong (or leave fan settings at default and the boost disables after a few seconds when it reaches 67c)

Thanks Dominik

Steps taken;

System image created
removed EVGA Precision x16 and folder in programs files
ran DDU v15.7.4.1 - clean and restart
re-installed nvidia drivers - 361.43
reinstalled precision from http://www.evga.com/precision/ -Version 5.3.10
download and ran ocscanner
clocked core to +96 (1500Mhz boost) and overvolt to 1256mV with kboost on. no increase in memory clock

Temperature reached ~67c and drivers crashed giving this page http://nvidia.custhelp.com/app/answers/detail/a_id/3633

As per screenshots below, now it wont even hit 1455Mhz / 1.2v

I have not yet tried the OC BIOS with higher targets. Involves modifying my own bios with the tweaker by the sounds of it.

It does accept overvolt with kboost up to 1.25 (actually more but crashes the drivers after a few seconds)

Sort of annoying as some people are easily stable at 1600Mhz boost on air when I am lucky to hit 1480

PSU Corsair TX850
i7 [email protected] - cpu perfectly stable (bench and games)
4x4gb memory
xonar essense st (pci version)

I'm fairly certain I'm having the same problem with mine Guest.

Mine will boost to 1390 odd then will drop in spikes when temperatures exceed 65 odd.

I do know I need some beefier intake fans on the front of my case though. The problem I have is the H100i fan cables are poverty short so need to find some extenders.

Once I have put another fan or two at the front I will let you know how I get on. Needs to be sorted though. I did catch it clock to 1550 when I overclocked it but it throttled hard when I loaded it. Like really hard. Think it went down to stock unboosted figures

Problem I have is the fans on the card only run at like 400rpm. Even though the card is at 70+ degrees. Catching it at 78-79 sometimes too. Which doesn't seem to healthy

Re the fan situation, try the custom fan curve and set it to aggressive. Im going to restore my system image in the mean time so it at least works at 1455mhz boost

Some. To be honest Guest, I think your expectations are too high. The 980ti is all about silicone lottery.

I would say a very large % of 980Tis boost in the 1300-1500 range stable. 1600 is very rare and, from what I have seen, bench stable only. Not game stable.

The classified is not binned, you are already getting boosts well above what is considered standard. I think this is a case of research, I bought a classified because I wanted the backplate, the custom PCB and power delivery on the basis that it would be more likely to clock well. I was WELL aware however that a lottery win reference card had exactly the same potential. I paid very little extra for the classified over any comparable add-in manufacturers offering so it was a premium I was happy to pay. I run under water so I was satisfied I would never have temp issues and my headroom would be limited by the silicone lottery and Maxwell architecture quirks.

If you want a hardcore overclocking card you need to be looking at cards like the Kingping and exotic cooling.

I thought more volts = increased reliability but more heat? Not more volts = more instability. I'm still tempted to flash as its dual bios and I am trying to reduce the clock decrease at such low temps (so I dont need 80% fan at 65c!)

It's very well documented that throwing volts at Maxwell will not net you any extra gains on water/air, only LN2. It's just the way it is with Maxwell.

I did think that more volts would make it more stable but hotter, but it seems more volts just makes the driver crash or total system freeze.

Maybe I do have expectation that are too high and should be happy with 1455 / ~8300mhz memory clock.

After all, this score I got isnt too shabby (Squad and GTA V playable)

http://www.3dmark.com/fs/7738986

I'll just say aswell that EVGA support has been very helpful and even offered to test it if i returned and/or RMA the card. I just think i have an 'average' one but with good memory. Im just a bit suprised it downclocks at such low temps - i will look into bios flash even if its to remove this (low temp throttle)

A point that i mentioned earlier also, is that software core voltage readouts cannot be trusted. You might already be seeing far and above what you have dialed in. The only way to know for sure is with a DMM probing directly onto the voltage probe headers on the card (which the classified has)
 
How much is a voltage probe, do ocuk sell them?

Am I being daft when it comes to EVGA Precision OSD monitoring? It doesnt appear at all in Squad even after adding the exe to the Precision X 16 server app (or removing it as it appears to be an exclusion list) Running Valley benchmark the OSD monitoring does appear and Heaven and 3dmark it appears.

I have tried hiding and showing it but nothing
 
In certain games precision and Afterburner too simply don't show up - it works except the OSD.

Look at GPU-Z here, he seems to have a better one?

http://www.overclock3d.net/reviews/gpu_displays/evga_gtx980ti_classified_acx_2_0_review/3

Despite it being the silicon lottery and possibilities of early throttling I think I'd still pick a classified. I can be happy with no to smaller overclocks but cab understand why you expected more than you got.

I did notice that review and others where they clock to 1500Mhz and above... however if you check the Firestrike scores they are 17k. A fair bit lower than my almost 21k. All I expect that is happening is that they are throttling to stock or slightly above, causing lower scores even though the frequencies show higher.

Same with multiple other reviews
 
No, on the hall of fame for single GPU (in above link) In that review I also noticed my heaven and valley scores are higher that the overclocked classified card. Think I will just crack on with playing Squad and ignore stated speeds in reviews because software seems to be dire at reporting correctly. I sacked of Precision and went back to Afterburner as it just felt clunky and also decided to show things like 0fps is OSD. Afterburner just seems to work
 
Yes, even if only for the support EVGA provide. Every question answered the same day. peace of mind that if it has coil whine etc then it can easily be returned. Plus its a fast card without overclocking

Heaven, Valley the OSD you can see is built in the tool and not the Precision OSD. Do you not see the OSD in any application beside of the benchmark ones? Have you already tried a later version of Precision?
