[PCPer] NVIDIA Confirms Clock Speed & Power Increases at High Refresh Rates, Promises Fix

post #1 of 41
Thread Starter

Last month I wrote a story that detailed some odd behavior with NVIDIA's GeForce GTX graphics cards and high refresh rate monitors, in particular with the new ASUS ROG Swift PG279Q that has a rated 165Hz refresh rate. We found that when running this monitor at 144Hz or higher refresh rate, idle clock speeds and power consumption of the graphics card increased dramatically.




We put NVIDIA on notice with the story and followed up with emails including more information from other users as well as additional testing completed after the story was posted. The result: NVIDIA has confirmed it exists and has a fix incoming!

In an email we got from NVIDIA PR last night:

"We checked into the observation you highlighted with the newest 165Hz G-SYNC monitors.

Guess what? You were right! That new monitor (or you) exposed a bug in the way our GPU was managing clocks for GSYNC and very high refresh rates.

As a result of your findings, we are fixing the bug which will lower the operating point of our GPUs back to the same power level for other displays.

We’ll have this fixed in an upcoming driver."

Should be a fairly easy patch.

Windows stutter and BSOD on 144Hz displays inc.

You know what's pretty screwed up? Fixes like these genuinely bother some people who want there to be things wrong with a certain company's products. It's ammunition.

In any case, this is good news and thanks is owed to the tech media for making Nvidia aware.

Would like to see this fix and use 144hz on desktop without stressing the card for no real reason.

Why the hell did it take this long for Nvidia to acknowledge this thing? People have been complaining about it for years. PCPer a bit slow on the uptake too. With all the hardware they go through I was amazed to hear them bring it up on a recent podcast as something they'd only just discovered.

It's the the full range color thing all over again. Nvidia just ignores the countless user complaints for years, then suddenly some website reports it and they fix it in a couple of months. I don't know what this says about Nvidia.

Maybe PCPer should do a story on why Nvidia's new GFE driver plan is a bloody stupid idea.

Wait, what? This has been a thing on a wide variety of monitors for years, since before gsync existed! It's not difficult to test either; it's even obvious from software sensors as GPU temperature rises by 15c and the power sensor literally displays the consumption in software quite accurately.

I remember this on forums way before pcper came up with it. There is even a solution for this for those who play in fullscreen mode. Glad to see Nvidia will come with a fix. Also note that companies do not care about what we say in forums. They care only when the matter goes widely public.

They have a rep in their forum. What, is he there just for show?

It says they're a company like any other who only sometimes bother fixing certain things when there's a certain level of widespread concern over it.

That would be really nice.
