Hot, Hot Prescott
I have a little desktop system built around an Intel D865GVHZ (socket-478) motherboard with a Celeron 345 3.06GHz Prescott cpu. W2k sp4, speedfan, cpuz, AVG, Kerio, AdAware, Spybot S&D, etc. Like all Prescott-core cpu's, it's always run hot. I had to uninstall Intel Active Monitor as the alarms were driving me up the wall. Also had to cease running Spybot scans because it ramped cpu to 100% for an extended period so the cpu temp approached 80 C. Was running Win Defrag the other day, noticed cpu at 100% and temp at 82 C (per Speedfan). I have no idea why the ordinarily i/o-bound defrag was using a consistent 100% of cpu, but I figure the 82 C was definitely in the ballpark for melting the 0's into 1's. There are 4 fans in the mini-tower case. All were working fine when I cleaned and checked previous to the 82 C. defrag reading. Has anyone had problems with the accuracy of a temp sensor on an Intel D865Gxxx board? My multiplier is locked. Setting priority has no effect so long as cpu cycles are available. Any idea re how I might slow the cycle speed so I can run certain cpu intensive programs? Thx, Will |

There are so many deals on new, used, or refurbished computers with plenty of muscle and none of Prescott's problems. I have a 3.0 GHz Northwood doing gofer duties (email, etc.). Surely there must be someone who wants to get rid of one. Robert. |

Especially a slow-FSB/cache-reduced one like the Prescott Celerons - P4/Netburst architecture chips are very memory bandwidth sensitive, and the combination of a slower FSB and smaller severely reduces the perormance on most of them. I'd guess that that chip, for most things, is going to be outperformed by a Northwood 2.4C or a Athlon 64 3400+. Possibly even a 3000+ or 3200+. -- Nate Edel http://www.cubiclehermit.com/ preferred email | is "nate" at the | "I do have a cause, though. It's obscenity. I'm posting domain | for it." |

I have a 3.0 GHz Northwood doing gofer duties (email, etc.). Surely there must be someone who wants to get rid of one. The manual sez: The board is designed to support the following: • Intel Pentium 4 processors in an mPGA478 processor socket with a 400/533/800 MHz system bus • Intel Celeron processors in an mPGA478 processor socket with a 400 MHz system bus See the Intel web site listed below for the most up-to-date list of supported processors. For information about Refer to Supported processors for the D865GVHZ board http://www.intel.com/design/motherbd/hz/hz_proc.htm And, of course, the fine, fine Intel URL sez "Page Not Found". :-) Actual table is: http://www.intel.com/support/motherb.../CS-026964.htm Doesn't distinguish between Prescott and Northwood. Due to the "Board Revision note", I suppose I'd have to open the case just to determine which Northwood would definitely suffice. Not much impressed with Intel product/support these days. Thx, Will |

According to Pricewatch, a 3Ghz Northwood (512K cache) can be had for about $30. It seems unlikely to me that there would be an incompatibility problem Prescott-Northwood. More likely the other way around. At $30, what you are risking mostly is your time. I *hate* installing heatsinks, but, if were in a mood to fiddle, I'd risk it and be prepared to throw the whole mess away if it went sour for some reason. If it works, you'll recoup your investment in saved electric bills within a year. Not much impressed with Intel product/support these days. That's a shame. Intel Core i7 920 is one of the most implausible bargains I've ever seen. You can buy them for $200. No wonder Intel is going to stop making them with three memory channels. Intel is pretty hostile to hardware hackers. That's a fact. They don't really want you as a customer all that much, unless you're going to buy more of their motherboards and chipsets each time you buy one of their processors. I don't think they really want people like you and me combing through their documents so as to get it right. AMD, on the other hand, knows that losing programmers with screwdrivers would be a big loss. As a blunder in the marketplace, Prescott really stands out (exceeded only by Itanium because of the relative investments). I suspect that most of those chips went into machines that sat at deskside doing almost nothing all day, so no one that mattered (i.e.; corporate buyers, naive home users) noticed what a dog it was. Intel didn't really get away with one there, but they didn't get hurt as badly as they might have. In the end, right now Intel has the better product, no matter how much of a dog Prescott was.
