Disable GeForce GTX 580 Power Throttling using GPU-Z
NVIDIA shook the high-end PC hardware industry earlier this month with the surprise launch of its GeForce GTX 580 graphics card, which extended the lead for single-GPU performance NVIDIA has been holding. It also managed to come up with some great performance per Watt improvements over the previous generation. The reference design board, however, made use of a clock speed throttling logic which reduced clock speeds when an extremely demanding 3D application such as Furmark or OCCT is run. While this is a novel way to protect components saving consumers from potentially permanent damage to the hardware, it does come as a gripe to expert users, enthusiasts and overclockers, who know what they're doing.

GPU-Z developer and our boss W1zzard has devised a way to make disabling this protection accessible to everyone (who knows what he's dealing with), and came up with a nifty new feature for GPU-Z, our popular GPU diagnostics and monitoring utility, that can disable the speed throttling mechanism. It is a new command-line argument for GPU-Z, that's "/GTX580OCP". Start the GPU-Z executable (within Windows, using Command Prompt or shortcut), using that argument, and it will disable the clock speed throttling mechanism. For example, "X:gpuz.exe /GTX580OCP" It will stay disabled for the remainder of the session, you can close GPU-Z. It will be enabled again on the next boot.





As an obligatory caution, be sure you know what you're doing. TechPowerUp is not responsible for any damage caused to your hardware by disabling that mechanism. Running the graphics card outside of its power specifications may result in damage to the card or motherboard. We have a test build of GPU-Z (which otherwise carries the same-exact feature-set of GPU-Z 0.4.. We also ran a power consumption test on our GeForce GTX 580 card demonstrating how disabling that logic affects power consumption.

atention quand meme de pas faire sauter vos nouveau jou jou

merci

jvais faire gaffe

Faire attention pour les GTX570, les régulateurs de voltages sont plutot faible sur certaine cartes et on tendance a griller facilement si on désactive le limiteur...

Plusieurs cas on été raporté sur le web.

Bien sur, lorsqu'on overclock ca fait parti des risques mais quand meme, mais tout de meme il est bon de connaitre tout les parametre en jeu!

C'est bon a savoir merci !
