anyway to remedy this issue?

If you overclock the mem, it will draw more power, something around 3-4w extra is what I saw pushing into power limit. Its a balancing act to stay under the power limit, so nothing you can effective do other than shunt mod for guaranteed power. It will bounce clks on the power limit, that just what it does smile.gif

Well this is strange.

  • Installed new 1080TI FE in slot 1.
  • Performed a clean-install of drivers + geforce experience (included) from Nvidia website
  • Updated MSI Afterburner to beta 4.4 (including rivia tuner statistics server) and rebooted) (to enable out-of-box voltage slider)
  • Updated GPU-Z to latest version. Restarted
  • Fired up The Witcher 3 (was previously working perfectly)
  • Now within 2 seconds of entering the menu the process is automatically ended and I land back on the desktop with no Witcher 3 tab to click on. (As if I never even started the game). mad.gif
  • Repeat last step 3x times... no luck. mad.gif

Back soon with an update (after I figure out whats going on).

I can get 4-5 extra FPS by getting my mem +500 alone in FFXIV 4K. I don't even get that with core overclocking so sometimes, if you are already at the limit of the core, it might be better to lower the core by maybe a bin and going ham on the VRAM.

Jayztwocents has a FTW3 (per his Twitter) so hopefully a review of that should be coming soon. Interested to see how the thermals hold up to the larger 2.5 and 3 slot cards.

HWiNFO64 reads both TDPs. Both TDPs limit the max power the card can draw. I can't find a way to increase the normalized TDP unless I flash a BIOS with a higher normalized TDP.

The shunt mod only affects Total GPU Power [% of TDP] but not the normalized TDP.



You can see my card (shunt modded) hits power limit because of the normalized TDP.

So this guy made a great post and it was kind of overlooked, myself including until I ran smack into the "normalized TDP" wall.

I started playing with lower liquid temps and higher clocks at voltages above 1.05v. I'm shunt modded and got the same normalized TDP limits in superposition @ 4k.

I'm currently running 2100 @ 1.05v with +550 mem to stay under this limit.

I confirmed the limit by lowering my mem OC to +0 and I was able to run 1.06 before hitting the normalized TDP wall.

Other benches seem to not show this. +rep on this one.

- CCleaner all files and registry (just in case)
- Installed fresh drivers from nVidia website
- NV Control Panel - change settings to 'Prefer Maximum Performance'
- Installed MSI AB 4.4.0 Beta 6 and setup
- Run Unigine Valley - same artificial V cap
- Follow instructions on Pg 1 to add vendor to .oem2 file (didn't exist when I opened it)
- Change to 'Third Party' voltage control in AB settings

Card hung around 1.000V the whole time. Intermittently, it would up to 1.012V or for a split second to 1.025V, but then immediately back down to 1.000V or even 0.993.



Now, I'm not concerned about the performance I'm getting AT ALL. Frames are good while gaming, which is what matters. I'm more concerned there may be something I have setup incorrectly, or with the voltage controller. The Temps all good for all runs, and I don't hit Temp Limit at all; just Power and Voltage limits.

Should I just chalk this up to Silicon Lottery and move on? Just can't figure why it would volt higher in PxOC than AB. thinking.gif

Thanks again! biggrin.gif
man, that seems odd for sure. i will say that a bunch of folks are running theirs locked at 1.0v to avoid all power throttling and b/c they get great clocks/frames at that voltage. tough call to not rma it, but, then again if you are happy with results it could be fine. if it is dying, you could always rma when that happens or becomes obvious.

Edit: after looking at your curve... try on a fresh set of settings and run it just +50 or something and see if it goes up to at least 1.063v. looks like your curve may just be set to the 1.0v challenge settings.

So I finally figured out this whole curve business ...

I re installed AFB and followed the instructions in post #1 about copying the string from the "Info" button in AFB ... something I didn't do before ... I added this to the "MSIAfterburner.oem2" file (the string I copied, related to my Seahawk X, was not in the .oem2 file by the way) ...

Oh yeah .. another thing I did this time when setting up AFB is to select the "Third Party" option under settings and next to the "Unlock Voltage Control" option ...

And now the curve seems to work much better and more consistently ...

For starters, I just went with the max of 1.093v and set it to 2050mhz at that point and things run fine through Witcher 3, Tom Clancy Wildlands, Metro:LL, ResEvil 7 and Titanfall2 .. I played for about two hours among all those games and only VERY rarely saw a power limit moment.

Things ran at 2050mhz for a bit but generally, especially with Witcher 3, would always drop down to the 2025mhz range ... or even 2012mhz range ... but generally always stayed at 2025mhz ... even when no power limiting was present; I did see lots of voltage limiting though ... at least I think that's what it was in GPU Z ... certainly wasn't power limiting though ...

I don't really mind these occasional fluctuations and not sure I can do anything about it ...

With the curve, I see much less Power Limiting than when not using the curve and just setting everything via sliders ...

Tired of messing with this thing.

Making me crazy a bit ... LOL

And how does this affect your score?

what bios' have 125+ power limit?

Palit bios gives you an extra 30 watts. That'd equal to running the card at 132% on stock bios. It's not going to report that of course but that's what has been measured by users.
