That's without any perfcap. I don't think it has to do with the Bios (Mumod or stock). It's something baked in I think.

Assuming you also have BOTH the power% and voltage sliders maxxed, this is not expected. Can I please see a GPU-z log of when this occurs? 0.1 second interval please.

Thanks!

W1zzard roams these forums but it's not a GPU-z limitation. This is either built into the BIOS or the driver because no matter was app you use to view voltages it has the same limit.

You have a GODLY GPU! Congrats! band.gif

And ya, water cooling is NOT a price/performance benefit. You have to forget all about that ratio otherwise you'll regret it. Having said that, building a custom loop and being rewarded with additional performance is very rewarding. We have to spend money on something right smile.gif

Here I just use the 3dmark and heaven to test stability , in addition to the games as well.

Your system is very good, congratulations on the setup.

one last question .

The bios let the fans at 35 % even with the right idle system?

Thanks bud smile.gif

If I understand the question, the minimum percentage/rpms defined in the BIOS is usually the lowest a custom fan curve would allow. The custom fan curve honors the MIN/MAX fan values in the BIOS. It is possible to go below 35% fan speed at idle, yes but it might require some BIOS tweaking if you cannot get that result right now.

why isent it the same layout for the voltage table i mean it has more sliders than the other

You are comparing your STOCK BIOS, which hasn't been "unlocked" yet smile.gif

Those sliders are very much needed for the MOD to work. You can download the same version you have in the OP wink.gif

Now unless you exited the game and then hit apply manually to change the memory overclock (obviously not what you did) what we are seeing is the memory dynamically changing. This is not behavior I have ever seen. Also assuming that you've thoroughly checked for other background apps running (never 2 overclocking apps at the same time and crap like that).

There is a possible explanation... one that you can test. I can see that you have power management enabled on the GPU. I have not seen/expected MEMORY clock speeds ever change with power management. Is it POSSIBLE that NVIDIA added dynamic memory speeds when power management is enable? IDK, I didn't test it myself yet either. It would make sense if they did (or maybe it is a driver bug like you said) to see what you are seeing.

Your first test is to change power management to "Prefer Maximum Performance". If the memory speed stays at 1957.5 then we can chalk it up to a new power management "feature". I'm just covering this possibility because I don't know if the latest driver(s) have added a dynamic memory speed feature or not.




Your second test (if you still have the issue at this point) would be to go back to previous drivers. Just go back to like January of this year or something and see if you can reproduce the problem (you don't have to stay at the older driver, it is just a test and will confirm if a driver bug or not). Select a custom install and check the "perform a clean install" option on the driver (that's all that most people need). I'm not going to recommend DDU anymore because it actually caused a problem for me that I cannot resolve without restoring a prior image of my PC. Coincidentally it is related to power management.

It would help if someone else has the same game and they can take a look to see what behavior they see.

If nothing worked then I'm out of ideas...you could "inventory" as many games/benchmarks as you can to see how many have that behavior and how many do not. Is it JUST that one game and nothing else?

Let me know smile.gif
Thanks laithan for the help!...and sorry for my late reply!

I solved the mistery! Simply, the problem was the game! Not my (new) system, eheh smile.gif Two friends (Italian guys from another forum) helped me with a test on the same game, and I can confirm this run in P2 Performance profile for the memory clock! We tryed in Windows 7 and 10, nothing difference, as well for different driver version and settings.

For solve this problem/bug I've made a little mod on your BIOS (now is a BIOS MOD MOD tongue.gif). I simply changed the P00 and P02 DDR standard values from 3505/3005 to 3925/3925. And now all run perfect! Also, in RealBench benchmark I registered my new record!! boxing3.gif This little mod make a ""big"" impact in OpenCL score! (from 6010Mhz to 7840Mhz)

Thanks anyway for the help and a BIG REP for you! cheers.gif

Hi there!

I have an Xtreme on air with this modded bios.

Next week im watercooling my entire system with ek blocks.

Should i change the bios to another to increase any voltage or something like that?

I have a 5820k with a 980ti Xtreme with 1 360 rad + 1 240 rad.

Thanks

Yes if you are going to slap on an EK FCWB you will be able to increase voltages thumb.gif

I'll need to know which Gigabyte revision of the xtreme you have (extract your BIOS) and I can edit one for you (and probably post it for others as well that have also added a block). smile.gif

If you need me to check the version for you then yes you can zip and attach to your post.
