Overclockers - beware of voltages in excess of Intel recommended max on Penryn (45nm) processors !!
See the following sad story:-
http://www.anandtech.com/weblog/showpost.aspx?i=428 Even if you use voltages nowhere as extreme as the Anandtech reviewers, you may still be contributing to a longer-term early-failure. These hafnium-gate devices may be a lot less accommodating of overstress than previous gate technology. It would be very wise to respect Intel's recommended voltage maximums and let other 'guinea-pigs' ( or those with lots of spare cash) fill in the MTBF vs voltage profiles of 45nm processors..

John Lewis As the geometry of silicon gets smaller, core or case temperature becomes a far less reliable guide to the Mean Time before Failure. Other mechanisms such as applied voltage begin to dominate. John Lewis |

After all, the stated CPU Clock rate is only 453 MHz, just a 53 MHz / 400 MHz = 13% boost above the stock clock for the Intel X48 1600 MHz specified FSB (plenty of Intel chipset motherboards NOT specified for 1600 MHz FSB operation will operate at that speed without VTT boosts.) And the sample is quantity one for the original post. And the original post is both unsigned AND in a forum. And the added comments by the original poster for this thread have even less provenance.

Phil Weldon The misfortune happened at Anandtech in extreme stress testing.. Probably the most respected PC hardware review site in the world for its technical authority. Er, Gary Key, the author of the article is one of their top reviewers. And he posted the warning as a practical instance of what can happen if you play with voltages in excess of manufacturer rating, as many other have found out recently when overvolting memory. Why not read the full blog and Gary's implied intentions before jumping in with both feet. Oh, btw. I do have quite a bit of stress/QC experience over quite a few years with standard digital silicon processes. It takes quite some time to fully establish the failure corners. Regardless of Intel's best efforts, I suspect there is quite a bit of learning still be to done even by Intel in that direction on hafnium-gate silicon. "Augustus" wrote in message And this was X-posted to the Nvidia and ATI videocard group for what reason? Because PC's have vieocards in them? Nope. Because those that read those specific newsgroups are likely be more than casual PC users and highly likely to be in the build-it-and-tweak-it-yourself PC community. I thought it easier to reach more PC tweakers that way than try posting to a myriad of motherboard newsgroups besides Asus. You do leap to the wrong conclusions rather fast, don't you? Been very long in these newsgroups or are you just a passing newbie? John Lewis |

hmm...
I brought my complete PC recently Overclocked proccessor (quad 2.4 OC to 3.2) and OC Vid as advertised. Wonder how mine will fare over the 12 months that is a legal requirement for warranty on goods sold in the UK. As a unit I've been informed, this would take precedent over individual item warranty requirements laid down by say, Intel or Nvidia. Also the selling company of the PC has the liability over individual parts manufacture. Interesting Alan |

But perhaps has forgotten. And that thread was inappropriately crossposted also. And concerned a source from another paragon of accuracy, "The Register"! But perhaps he DOES remember those postings since he just paraphrased my January 30, 2004 reply to him in this latest thread: "Perhaps you should familiarize yourself with the thread before jumping in."

You are bonkers if that is what you think. More so if you are in any way affiliated with that site or its advertisers. Anandtech is perfectly average in every way. |
