GTX280 stuck at 3d speeds even at desktop.

[Lfctony]

I have used a GTX280 on THREE Intel chipset boards and not one of them had a problem falling back to 2D speeds when not gaming... These stupid, jumping-to-conclusions people help no one...

[slaWter]

It could be a VGA BIOS setting. Because my BFG OC never clocks down. No matter what drivers or monitor configuration I use.

[zeejay]

Well, I just discovered that if I have dual monitor set up then the card does not throttle back, but when I disable the second display it throttles back to normal 2D levels...

Interesting...

Surely a driver bug..



Figured this because I received my 24" Samsung T240 today and figured it was worth a try...



Thank you, i spent an hour last night trying to figure out why my card wouldn't clock down.
Disabling my 2nd monitor did the trick. Seems like a driver bug, also im running an eVGA 680I board so it's BS about it only working on Nvidia chipsets.

Glad it worked for you :)

And yes I think the Intel chipset theory is rubbish also..:rolleyes:

[zeejay]

Well it works until i play a game anyway, then afterwords it won't clock down anymore till i reboot.

[particleman]

It is not an Intel Chipset problem. I am having this problem with my 780a 280GTX SLi setup, I did not have this problem on my Intel boards a 975x, P35, and x48.

I notice it seems to get stuck at 3D speeds if I have internet explorer open in Vista, close IE speeds drop down. Simple solution use Firefox.

[crainger]

Must be something in IE that triggers 3D. I found a few times Java would do this. ::(:

Same for me sadly. Hope they fix this soon.

UPDATE

The clocks assume full 3D mode when watching TV through WinTV too.. I would not think this is "normal" behaviour... not exactly stressful 3D rendering... or am I wrong? (ack)

[dante]

I have a Intel chip set and I have to manually set fan speeds. Before I play Crysis I set it between 80 and 90 Percent. When I quit the game it stays at that same speed unless I go into the settings and wind it down.

[LitHiuM]

Oh my goodness.. I keep discovering stuff that makes the clocks jump to full 3D mode and stay there... :surrender

This time it's Google Talk would you believe.. wth is going on here :fu:

This REALLY needs to be fixed soon.

its a driver issue. nvidia broke the sensitivity and the clock domain switching since 177.73. it was working perfect on Intel chipsets on every driver so far till 177.70. 177.73 completely broke it. 177.79 broke the detection sensitivity

[DarkOneX]

Actually the clock speed throttling works fine for me with 177.79 drivers UNLESS I overclock my core to 700Mhz, then it quits working for some odd reason, it will then get stuck in 3D. However like right now if I leave it @ 600/1400/2400 then it throttles down to 300/600/100 fine.

[LitHiuM]

As yet I've not touched overclocking. Waiting for the G200 full cover water blocks to get here.

[mikeyakame]

I believe I understand the reason behind certain problems such as particular clock frequencies and problems related to them. Apparently the G200's use the internal PLL Ref Clock Gen where it can, and where it can't it falls back on the Southbridge PLL Clock Reference which turns out runs lower than the 108MHz reference clock internally. This inturn appears to cause clock calculation errors and resonance in the clock domain for both the GPU and the SB intermittently (sometimes more other times less). It appears I've fixed the problem on mine simply by running PCI-E Frequency at 112MHz. That allows for a small percent of out-of-phase clock correction. Intel SB's generally handle upto 120MHz at most on the SATA bus. 117-118 is safer bet. This will mean increasing the SB voltage slightly to compensate for raise in PCI-E frequency. 0.050-0.075V is more than adequate. If you want to see if this is the problem or not. Set your PCI-E frequency in bios to 108MHz and see if any random weird behaviour occurs. Slow downs, timeouts, graphical glitches, out of sync screen drawing, display adapter not recovering and requiring a reboot, delays / hanging in keyboard or mouse use, etc.

In a perfect world PCI-E at 108MHz would be right, but since at least on my card Nvidia did a poor job of insulating the circuit board electronics from interference, jitter, resonance, etc from external sources it causes more problems for everything else due to the chatter which happens intermittently on the 104-109MHz frequency range.

I have the card downclocking fine on a G31 here. If it doesn't work for you, that doesn't mean its broken...

[mikeyakame]

It downclocks fine for a while then it stays at 3D clocks if you raise the load high for a decent period of time. It could be bios related to certain cards, I flashed my 280 with a newer bios from an XFX XXX card and it seems to work better than the older bios version my card came with. Mine came with 62.00.0E.00.02 and the XFX XXX had 62.00.0E.00.75, perhaps there was some changes made by NV in the core bios code who knows, but it's not as bad now, still not 100% but its not 0% either.

[DHP]

Weird. I had this problem five minutes ago. Card was stuck @ 3D speeds... I saw the temps being 55C idle. Normally my cards run @ 45C idle.

Rebooted, problem gone.

179.92 drivers, Vista 64 bit, further specs see sig, cards @ 650/1399/1150 (since I have them).


Weird... Never saw it before... Maybe coincidence or some program that triggered this. Edit: I think it was a web based thing which triggered this.

Please try to find out what prog/app caused this and we can add it to the list. just saw your edit I, and others, have already notified nVidia that dual display, WinTV, Google Talk and MSN messenger (Live messenger, not clones like aMSN) cause this. Others state that IE7 also cause it.

This issue really needs fixed. Fast.

F.Y.I. I suffer this issue with all drivers from .41 to .98

[BCKator]

I use Rivatuner(RT) to force lower clocks when not in 3D on my 8800gtx. It sounds like the gtx280 is supposed to do the same thing automatically but, if that fails, shouldn't I be able to do the same thing w/ RT?

Well, I don't consider it an issue. They've made the 3D detector extra sensitive in the 177.79s+. That's to deal with the downclocking issue. Many programs make the cards go 3D, Steam, Internet Explorer etc. That's how it is. They could have made the cards 3D only from the beginning. Now we have to compromise if we want that powersaving, or deal with stability problems(downclocking ingame etc.)

BCKator, the card also drops its voltage. You can't get that with RT. Besides, this should happen automatically, not manually. The problem is that the sensor is extra sensitive and goes back to 3D with any type of video card work... Some programs just trigger it in the Windows desktop...

[Tolden]

The card goes into 3D mode when login into Steam (no games, just the launcher) or remote desktop (Steam.exe and mtsc.exe). I think it will switch to 3d mode with more apps, but I did not make an intensive test.

[Shocky]

Identifed this problem months ago, they don't drop down to 2d or powersaving mode then using two displays, amazed this still hasnt been fixed.

[namuk]

great how everyone jumps to conclusions. maybe it is a bug, not some mass conspiracy.

or maybe just a feature that is not possible on intel chipsets.

thats what is was thinking mine never downclocks have been looking into this doing me nut in . in everset it shows what the card is capable of in 2d 3d . i just do not get it

[bacon12]

I never have has this issue with my 260 so I can't say this works, but maybe you guys can try this.

thanks so set to max you do not get downclock set to moderate it downclocks? going to have alook at them settings
