Nvidia GTX 980 Owners Thread

No just wondering, some nice clock speeds. What are you testing for stability with and how exactly are you changing the voltage/power limits?

EVGA Precision X... I'm more familiar with MSI Afterburner which I was using for my 970s... but felt like sticking with EVGA's utility for the heck of it. I think they're both the same (rivatuner?) core running beneath a skin.

I'm enabling kboost to get a static clockspeed & testing with Heaven & 3DMark... they gave me a good idea for stability with the 970s.

Also setting fans to 100% for testing to minimise temps.

Number 10 Heaven & Number 6 Firestrike air-cooled scores :D

Ah, so it fits OK? Think I'll just pull the trigger, unfortunately the back plate is out of stock so might need to source elsewhere.

** Edit **

Also, will your stock back plate go back on if needs be? I assume it was just fixed with screws as normal?

Yes it is - so should go back on with the wb.

Well that's the waterblock/backplate fitted.

The bare card


Quite a lot of unnecessary stock goop on the gpu. Not good!


All cleaned up


That's better with all that crud taken off. Rest assured I did a better job of reapplying than Gigabyte. I used MX4.


In it's natural habitat


Currently idling at 27c / load 40c :D

Now to get around overclocking this properly. . .

Lovely, I'll get mine under water next week. Thanks for the update.

Cheers, Mark.
 
Well just had a good session on BF4 with a little boost.

Got my settings currently:

Core Voltage: +60
Power Limit: 122
Core Clock: +160 (1552Mhz Boost)
Memory Clock: +495 (2000Mhz)

Running real sweet and a noticeable gain in fps!

BF4 plays so smooth, and best of all my system is nice a quiet under load.
Can't believe how cool this cards runs under water, highest it went was 42c. Very impressive indeed.

Also no coil whine either.

Will push for higher clocks tomorrow. . .

Yes... that or EVGA Precision X really... I'm not sure which I prefer yet, only just started using the EVGA software.


Woo... bumped myself up to 5th place on air :D

thanks, im going to give the evga one a try. Are there any links to guides on this or could you recommend me any base overclock settings to start from? Im using the standard cooler.

thanks
 
I've just switched back to MSI Afterburner... after a bit of testing, I think it's a bit better.

It depends on which memory you have.

+100 core
+250 mem

will likely work fine on most cards... maybe a little voltage boost (under +50mV)

for the other type of mem, you should make +500 easily.
 
Few questions;

What's the normal idle temp of a strix?

I presume the 3dMark physics tests are a CPU test, and physx is not used?

Am I correct in saying a G3258 would be a significant bottleneck to 3dmark scores when paired with a 980?

I had 2 970s and now a 980, all had Samsung memory and wouldn't go much above +300. Is memory OC susceptible to voltage?
Click to expand...

My 970s, I had 1 with Hynix and the other with Samsung.

The Hynix would struggle to see +300... the Samsung would do +500

These EVGA cards, oddly - GPUZ is not reporting the memory brand - although they will run quite happily at +565 - so I'm assuming samsung.

I haven't needed any extra voltage for the mem overclocks, only to get the core stable.

My 970 strix was sitting around 50C at default settings (it keeps the fan off until it reaches 50C). You can edit the fan curve to keep it cooler if you like.

This is the fan curve I have settled on as a happy medium for me... I like things as quiet as I can get them. It's working well for these two cards.

25% fan speed is practically inaudible & keeps the temps around 30C idle, default fan off setting would have the cards sitting around 60C idle as that's the temp before the fans flick on.

With this fan profile, the cards don't exceed 70C and the peak load noise isn't any more than my 970s.

When the fans on these cards go above 65% though, they're noisy little buggers... (I had them running at higher %age values for benchmarking & overclocking tests).

Yes, that CPU will be a significant bottleneck, especially in 3D Mark.

I have the samsung memory, here are the settings that I have applied at the moment.

do they look ok or shall i go higher on the memory? i have the kfa2 soc 980
