No fix so far!

Can i ask you why you need the modded bios?
Im asking because i wanted to flash my cards just to get rid of the TDP limit..but i had the same issue as you!!!

So i opened my BIOS on Kepler Bios Tweaker and modded the TDP limit from 106% to 130% smile.gif


How did you tweak the voltage/TDP? This is all I get, with the max voltage still being 1.21v

Maybe you can post what your power table looks like if that's what you changed?

I unlocked voltages (up to 1.3v) using the soft mod!
The only thing i did for the TDP Limit was to open my bios in Tweaker (i have v1.25) and tweak the Max (mW) to 130%...

Thanks, I took it up to 130% but have it running at 122%. You said 130% should give 1.3v, does the voltage scale up based on the clock speed that the gpu runs at depending on the load? Or does it run at 1.3v as soon as you move the TDP slider to 130%?

My lightning is back it the store with a full refund. Now to decide what to replace it with.

Do I take a chance on another Lightning or go EVGA?

On the plus side I could probably get a 4Gb version now. Is it worth it?

I personally like using EVGA. I have had three cards by them, a 470, 560Ti, and now my 770. All performed great. And the reference cooler design is just awesome, glad EVGA kept reference design on some 770s!

There is certainly nothing wrong with EVGA. Ive used several products from them. Great service and great giveaways. They give away a lot of stuff other than the games listed on the vendor sites. Be sure to sign up for their newsletter and register the card. As for 4gb VRAM. If the price is right I would do it. It may or may not become relevant in the life of the card but cant hurt anything.

I get about 80-160fps (with the 80fps being 1 second dips cause bf4 is badly optimized)

That's at 1440p.


Anywho, can someone direct me how to voltage unlock my 770gamer?

Bought one then price went up so got a lightning. Got the lightning unlocked but can't get the gamer past +12mv and need to otherwise overclocking barely works at all.

They won't scale well in a conquest large maps with 64 players. I can't even push my single 770 to 99% usage.

That reminds me, Im surprised its been so long since we got another driver update. My gpu use is everywhere on bf4 as well, hope it eventually performs like bf3 did on a single card.

Gpu use is crazy on bf4

Bf3


BF4 lol

changing TDP will not change your voltages
