Also great news - at least that way you can try with each BIOS and have a before/after comparison. smile.gif

I actually am downgrading my previous dire warning to a gentle 'caution' - I took a closer look at the datasheet for the uP9511p phase controller that Nvidia used on the FE cards, and it doesn't look like it supports any sort of modification of phase balancing in software - all of the current limits and sensing are all programmed physically with resistors on the board.

AMD had this capability with the controller they used on their RX480 boards and were able to have it draw less power from the motherboard slot with a BIOS flash, which is why I was a little worried.

My only other worry was that perhaps they changed the current sense resistors from the FE to the Strix board, but I double checked and both boards use 5 milliohm resistors to sense the current for all 3 power sources, so we're good there too.

According to my AX1500i log the 8 pin power connector is pulling about twice the power of the six pin power connector. Max 20 amps to 11 amps on six pin. redface.gif

Anything to worry about?

Nice work! Could you hit 2100 before?

Edit: Also can you flash back to stock if needed?

I'm getting 2100 core at 1.075v 6132 memory, Power Limit never goes over 111% an entire Heaven run, and as you can see by my GPU-Z file it never throttled or lowered core or voltages once the entire Heaven run, no shunt mod.

GPU-ZSensorLog.txt 35k .txt file

Here's how I did it biggrin.gif

nvflash_5.353.0.zip 3031k .zip file

1080ti_strix.zip 154k .zip file

Unzip NVFlash and the Strix bios to a folder.

Disable your video card in Control Panel in Device Manager.

Run an admin command prompt and cd to the folder you made.

Do in command prompt:

nvflash64 --protectoff.

Then do:

nvflash64 --save filename.rom

to backup original bios.


nvflash64 -6 biosfilename.rom



Reboot, if the card is not enabled in Device Manager, enable it, reboot again. Good idea to reinstall Nvidia driver, reboot last time, done.

For more than one card.

nvflash64 --list

nvflash64 -6 --index=0 BIOSfilename.rom

nvflash64 -6 --index=1 BIOSfilename.rom

Choose yes when asked to override mismatched IDs.

Let me know how your testing goes! See if you can do 2114 Mhz without power throttling!

Are you hitting 1.092V consistently now? And also, can we backup our BIOs and reflash it for RMA purposes? Thanks for testing this out and being brave!

I have 2100 at 1.075v with zero throttling.

You can reflash it, yes, just need to do the nvflash64 --protecton command when you are done to lock the BIOS again so they have no idea you did --protectoff and flashed it from original.

Trick I figured out from my Maxwell Titan X days biggrin.gif

Don't suppose you have similar readings from the FE BIOS? I'd grab it myself but I don't have a fancy corsair PSU smile.gif

I could, at 1.093 volts and it would jump all over from 1.050v to 1.093v and the clocks would jump all over as well of course. redface.gif

As you see by my GPU-Z log not once during Heaven does it vary from the 1.075v max and 2100. band.gif

My best timeSpy score with Heaven at 2100 before at 1.093 not using Strix BIOS was about 10758. frown.gif

No, and I'm getting such good results with this BIOS I don't want to flash it back even to test. rolleyes.gif

Edit: Actually I'm going to flash it back to test, you've been really helpful and are very knowledgeable.

Least I can do. smile.gif

The 50 and 63% are fan speeds. Gpu usage is 98-99% on both. Not sure why Msi has it arse backwards on BF1. I'll take another one showing all threads.

Just got my hands on a Strix last night and so far it's seems pretty beastly It's boosting into the mid-high 1900s straight out of the box which I'm pretty good with. Fans don't get too loud but sometimes pulse on and off when not gaming which could get annoying (although it looks like it might just be after gaming it does this, need to test more).

Issues I have with the card (any help or suggestions much appreciated):

- When it boosts up the boost isn't stable, it jumps around constantly by small amounts even though the temp seems stable
- I'm getting jittering every few seconds, which could be related to the boost jumping around. It isn't unplayable by any means but it's annoying. I have vsync on and a frame cap at 58 fps on a 60Hz monitor. These settings were fine with the 980 Ti
- The colors seem washed out compared to my 980 Ti (same settings). I've tried adjusting settings in the NvCP and on the monitor but I can't seem to get back the 'richness' of color I had before. I'm using a display port cable if that makes any difference.

I should post a screen of what the boost is doing but I'm pretty short on time at the moment sorry and am just testing the card quickly when I can. I'll get to really work it out in the weekend hopefully.

Thanks to anyone who can help thumb.gif

@All

If a lower-end card can run a certain game at say 120fps without being CPU-bottlenecked, can the same game be run at 120fps also with a 1080Ti that is CPU-bottlenecked? I'm not sure if I get this correctly but the CPU gets bottlnecked with a 1080Ti past the fps rate that you are getting BEFORE the upgrade with a lower-end card, right?
