XFX GTX 260 216p - 2d mode not working Oi Recently I bought a new rig (Asus P6T, i7 920, XFX GeForce GTX 260 216) and everything was going ok, until I realized that my card doesn't work in 2d mode - it works only in 3d mode, always running the cooler @ 40%. The temps in idle mode doesn't fall 47ºC, but at full load I get 87ºC (remember: fan @ 40%). Why my card doesn't have 2d mode option for save energy and temp? =( I use the last official driver from nVidia, but I've already test the last beta one. There's no option for power consumption in nvidia CP. Any help?
First question, are you forcing the fan to stay at 40%? If so I would put it back on auto. As far as the card downclocking in 2d mode (is this what you mean?) - certain applications can force it to not downclock, doesn't just have to be a game (3d application)... Watching videos with cause clocks to change, etc... So the other question is what applications do you have running? Experiment by closing applcations or preventing them from starting.
Now I force the fan to stay at 60%. 40% was the original configuration ("auto"). Even when I start the Windows, the card already clocks @ 3d mode. I've deactivated almost everything, and the card stays in 3d mode. I've tried it, but doesn't work. With or withou Aero, I get always 3d mode clocks. Well, when I configure to "Auto", the Fan can go to 50% - and reaches 75°C. Not too bad. But I want to save power (and increase "lifetime" of my RIG ) getting 2d mode clocks for my VGA
Same issue here! I noticed that my GTX260 also doesn't go back to 2D mode after closing some applications like Folding@Home for example or after I close a game (Dead Space)! The card remains in 3D clocks . I'm using the 186.18 drivers and I hear the new official beta ones have better power managment so maybe I'll try those drivers!
Are you guys on Vista 64 ? Because I have the exact same card than you and I have the option, and it works instantly after I quit a 3D game. It didn't work when I first installed the driver after the first reboot. I have to do another reboot before everything works fine.
I'm using Vista 64. And I tried the new beta driver. Nothing change. Remembering that my card boots @ 3d clocks
I think having 2 monitors hooked up to the card can cause not to downclock. My gtx280 never downclocks.
I also have a XFX GTX260 Core Edition. It's the 216 shaders model with 55nm. I also noticed that it never throttles down and always stays at 3d clocks. No matter what drivers or what OS i used. So i wrote a ticket on the xfx homepage and the guy that answered confirmed that this card does not support 2D throttling. So I looked for another gtx260 bios and found one from zotac with the same device ID and board ID, flashed it onto my xfx card and guess what... The 2d clocks worked immediately. But the problem now is that my card doesn't like to overclock with the zotac bios. With the original bios i could run the memory at 1200MHz without problems but now I'm already getting heavy artifacting at 1050Mhz. I'm not sure whats causing this since the memory timings and voltages are identical on both bios. Anyway I just don't get why xfx disabled 2d throttling on that card. I just wish they would release a bios update where it's working.
