Warning: Sandy Bridge Hardware Level DRM, Killswitch, & H67 P67 Recalls!  

post #1 of 484
Thread Starter 
I don't like this. I may just keep my 950 after all. Maybe the 950, 920, 980x, etc. are the last good chips without some kind of weird hardware level DRM inside?

http://www.technewsworld.com/rsstory/71568.html

^From article: ""These are features built into the hardware, so if you're a Netflix (Nasdaq: NFLX) or a Warner Bros., you can program a time clock into a movie or code it so it's good for only a certain number of days after the consumer downloads it," In-Stat's McGregor pointed out. "It's all related to DRM."

http://securitythreat.info/sans-internet-storm-center/intels-new-processors-have-a-remote-kill-switch-anti-theft-3-0-sun-dec-19th/

^From Article: "Definitely, this new feature is something to pay attention to, as potential vulnerabilities in the implementation can open the door to new remote attacks, starting with DoS."

Plus the recall on all currently shipping h67 and p67 motherboards for these sandy bridge processors due to the Cougar Point Chipset defect, basically a global crisis of all p67 and h67 motherboards being recalled!

- Seems to me that It's one big issue to the next. It'll be interesting to see how everything else plays out for the next year. One question is...is this really a cougar point chipset issue? Or is there a real security vulnerability from the Killswitch feature that Intel is disguising as a chipset problem? Hmmm...interesting indeed. I would say don't buy a Sandy Bridge processor for at least a year's time. That should be enough time for Intel to work out the kinks with DRM, KillSwitch, and new Cougar Point Chipset Issues

Some interesting Facts!

1) Cougar Point Chipset affects all currently shipped h67 and p67 motherboards as of January 31, 2010. How does it affect it? From Tom's Hardware:

"The issue is hardware-related and requires a silicon-based fix at the metal layer, which of course means that all of the currently-shipping P67- and H67 –based motherboards are affected. It’s severe enough, especially for the enthusiast community most likely to be populating multiple SATA ports and pushing heavier I/O workloads that we’d want to recommend holding off on Sandy Bridge-based builds until boards with a fixed version of the chipset ships out."

http://www.tomshardware.com/news/cougar-point-sandy-bridge-sata-error,12108.html

2) Sandy Bridge's killswitch works even without the PC being powered on (over a 3G network)! All future Intel CPU's will be equipped with one.

3) Killswitch renders the cpu useless.

4) The new Sandy Bridge have DRM built inside the chip. It cannot be removed through software. As long as you have a Sandy Bridge CPU, you automatically have DRM that can't be removed.

5) DRM is an acronym for Digital Rights Management, a broad term used to describe a number of techniques for restricting the free use and transfer of digital content. DRM is used in a number of media, but is most commonly found in video and music files.

6) Many PC enthusiasts dislike DRM due to the problems associated in the past with software DRM. Many reports of issues with DRM in games, etc. have been reported, and the majority of consumers dislike it.

7) There is a debate about the KillSwitch and some security vulnerabilities. Taken from the 2nd link: "Definitely, this new feature is something to pay attention to, as potential vulnerabilities in the implementation can open the door to new remote attacks, starting with DoS."


Some interesting issues at hand:

It’s more likely to manifest in configurations with lots of data being moved across the SATA 3 Gb/s ports—that’s why OEMs are encountering a problem now. The company says it would have expected roughly 5% of systems to be affected over a three-year period. That's a serious enough figure to compel Intel to halt shipments and incur a total cost to replace/repair existing systems of $700 million.

Think I'll be looking into Bulldozer when it surfaces.
I'll be keeping my current rig, but I'd like to build an AMD rig!

Resale value on these chips considering the DRM and that Killswitch issue might thwart people who like to upgrade frequently. If you buy the processor used and the original owner uses the killswitch and deactivates it...hmmm...another interesting problem with the killswitch. Plus if hackers find a way to use the killswitch and just wreak havoc on you, disabling your pc...

I knew there was going to be a catch somewhere...... Don't worry though, there will be a workaround soon enough thumb.gif

Perhaps some motherboard manufacture will put a BIOS level disable option for this hardware DRM thing?

I don't care about it. If they never told us about it, you would never have noticed.
