Nvidia GTX 980 Owners Thread

Too add, EVGA seem to make a better product. KFA2, in particular the SOC was nowhere near the quality of this Card.

I ordered a backplate for mine, which should be here for Monday. I'll post pictures when I fit it.

Very true, probably why it was cheap and sold it self on having three fans. Yet this has two powerful fans and it's something like 30C cooler than the SOC :rolleyes:

You would expect it to be "better" in every way for the price difference. Paying £399 for my SOC has been a good buy, not a great buy due to the circumstances of making this purchase and returning my 970.
I'm not interested in running benchmarks and just add 100mhz to the core clock and 200 to the memory and I'm fine. I'm not really sure if I need to do that as using adaptive sync does a good job with Dying Light at 1440p.

If the SOC had not been on offer at the time I was buying the card I doubt I would have paid its typical full price over that of other brands I'm more familiar with though.

Sadly I couldn't see much of an alternative to the 980 at the time I bought one, certainly not on the red side.!
 
Okay, you will need the Maxwell BIOS tool and the version of nvflash that does not check for certificate's. Dr Google those and post screen shot of your voltage table from the Maxwell tool.

When I get home I'll help you more.

I've got them both, I'll get the screenshops up tomorrow, I'm just about to stick a film on downstairs.

Okay, sounds good to me. Enjoy the film.

Cheers. Here you go:

Do you need the ones lower down as well?
 
So, the top three would need to be changed e.g

Top line 1262.5 - 1262.5. To the voltage you want (max is 1.3 I beloeve) for both values.
Second line change the right value only
Third line, change the right value only.
P00,P, change the right value.

i did not change any other clk vaules as there where higher than what I set above. Is seems that the top three are a reference the card uses during the other clk vaules and determines if the voltage slider in AB or what ever you are using actually does anything. Eg, my card had a hard limit of 1212, which the card hit right away. So, changing the sliders did nothing for me until I changed it.

Looking at your table, you already have a max of 1262 ref, which is higher than the 1250 I've set, so do you need to raise yours?

If you do, do so at your risk (kinda goes without saying) and ensure that you disable the card in device manage and turn off any firewalls and av during the flash.
 
I've downloaded Maxwell Bios Tweaker from the following link and all seems OK...

However, when I try to download NVFLash v5.206.0.1 from the following link, Google Chrome steps in and refuses the download with a warning about Malware..

http://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-970-980

Is the Chrome warning a false positive?

I used the same link and Chrome issued the same warning. I used IE then preformed a virus scan on the zip, then the contents just to be sure.

I will have a think and maybe play around with it later.

What card did that bios come from, I'm sure you said a FTW?

Mine? It's a Hydro Copper.

You didnt need to use IE. You just go to downloads in Chrome and click on "recover malicious file" and it saves it properly.
 
S2KIP just be careful what you are doing. If you look at previous posts most people seem to be changing the right value from 1212mv to 1262mv. My default BIOS settings are exactly the same as yours. The first and third are already at 1262mv. Whats even stranger is that the P00,P right value is 1600mv. So changing this to 1262mv is actually lowering it by a lot. So in my mind the only one you can increase to make it same as others is the second value from the top changing it to 1262mv from 1225mv.

Also in Afterburner my power limit at 100% the slider is not in the middle it is right near the top end. The max I can get is then 109%. From what I understand it this makes sense because of the top value in tweaker reading 1262 - 1262mv probably means the card is already at 1262mv = 100%

CLK 74 on the Voltage table seems to be the important one too to alter as it links to the maximum stable boost clock set. See link bottom of this post for a good guide I found.

I've not done any bios tweaking since the gtx 580 but ideally need to find out what each of these values represents.

edit:-

Have a read at this guide its the best one I could find so far to explain what all the settings do around voltage/overclocking

This is a good guide to follow it shows better screenshots -

I've submitted a Support Ticket to EVGA with a couple of questions.

1) Why are the volts so low on the FTW (lower than the SC), it can't be cooler related as they are the same. And the FTW has extra power phases

2) I provided a copy of my modded BIOS and asked if that is the correct way to raise the base voltage.

3) Can a BIOS Engineer provide a newer BIOS with higher voltage.

I'll keep this thread posted with any updates.
