Nvidia GTX 980 Owners Thread

Reading the above regarding safe Volts, what Volts are Safe?

My SOC jumps between 1.200v to 1.225v on its own. When it drops to 1.2 there is a drop in GPU Frequency too but I'm well within the Power limit (say 70 - 80 %).

If I use AB and nail 1.225, it's stays there and I can clock higher.

Thoughts for those who own a SOC?
 
Galax for me.

A bit of coil whine I can put up with and from what i've seen if you 'burn the card in' then it does reduce a fair amount however if it's terrible, i'll simply take it back to OcUk on Thursday when I drop my 970 off and get a replacement.

Run GPUz while gaming and what does PerfCap reason show?

best of luck to you and if mine does whine then I can't hear it above the hack and slash of chomping through Zombies on Dying Light ;)

I find it a good value card for what I paid compared to the others.

You're probably noticing instability at higher voltages due to the increased pcb, vrm and memory chip temperatures. I noticed the same thing back when I had a reference EVGA 980 SC in that voltage barely seemed to help my OC and higher voltages caused instability. However, on my current cards I've noticed that increased voltage does actually help to improve clocks and is probably down to the cooling solution on it (includes full coverage of vrms/memory chips etc.)

Also I found the only way of really controlling voltage would be at bios level. Due to the way boost states work I found that afterburner voltage adjustments aren't clear or precise enough. I simply edit the bios with an additional increment of voltage at the highest boost state (74) and that works a hell of a lot better than afterburner.

Also your point re custom bios is correct. This is especially true on custom pcb cards as the components, power delivery etc can be completely different. I flashed an EVGA Bios on my old 970 g1's and it caused all manner of artifacts, when I copied the same settings into a version of the G1 bios, flawless. The maxwell bios tool is fairly easy to understand once you've done it a couple of times.

If any fellow inno3d ichill owners want a copy of my game stable and benching bios versions let me know.

Thanks for the reply. Did you have any way of monitoring the other temperatures? My plan is to put the card under water using the full cover block so it'll be interesting to do a before and after comparison. While the core temp runs cool enough I did wonder if high vrm temp is contributing to the results I have been experiencing.
 
Still struggling with noise and temps, just bought some modders mesh and a Megaflow 200mm fan. Going to remove the window on the 540r and replace it with the mesh and mount the fan as a side intake. Managed to get another gentle typhoon on the bay so i'll swap the 2 PK3s and fit three Ap15s in the front and link them to the LT5. Surprised how hot they are tbh.

Cheers for that.

I wont be messing with my Bios though. I am currently very happy with the OC I am getting and the stability it is proving. I am not confident I would be able to do it now "cos of my peepers guv"

However

I so have a 20mV on my benchmark OC

I have found this is needed to prevent driver crashes in Fire strike (Nvidia driver)

Heaven does not care less until I go over 151 Core clock then it crashes as well. Runs for 2 hours+ on 151. Also my Vram deteriorates after 230 and I get a massive drop in performance. The card does not get over 63c though.... just sits there, all busy and laughs at heat....

Only issue thst is very obvious is OpenGL Hates my overclocks.
 
Yeah crashes out , reinstall the driver and experience seperatly sorted it for me .
New 980s arrived , bottom card hits around 67 and top card hits 81 under 3D mark extreme , slightly cooler than my 970s ( 73c ,83c )

Absolutely zero coil whine on my SOCs as far as I can tell , scoring 11100 odd at stock on FS extreme with stock 5820k . pretty I'mpressed as had to go balls out clocking on my system with 970s to reach 10,000

Fans are stuck at 52% however it's still virtually silent at that speed so unless I'm gonna tweak my bios I'll leave it as it
