Default Re: What is the PerfLevelSrc hack ?

Yes, it is. And, no, the driver isn't always stable doing those frequency changes. That is in fact the way the PerfSrcLevel hack came into existence. The clock changes were causing machines to hang.

No, you are wrong. Even if XID errors were caused by heat, that does not imply that the heat problem is because you are taxing the capabilities of the video card. It could be a driver problem, BIOS problem, ventilation problem, etc.

Why not try to get the performance that your card is obviously capable of without risking shortening it's lifespan? Having users throw money at a problem only allows vendors to continue to produce sub-par hardware and drivers. Buying a new card is the worst possible solution considering that his hardware is obviously capable of doing what he wants.

I also don't understand why you are calling me "cheap". A laptop is not a desktop. You can't just wander into a CompUSA and buy an upgrade for US$100. It's all or nothing. You buy a new laptop or live with what you have.
