Normally, when a chip is being fabricated, an insulating layer of film is deposited to electrically isolate the chip. That film is normally removed from the die pad area, where the chip interfaces with the pins that connect it to the outside world.
In this case, the thin film on a pad area was only partially removed, causing the real-time clock circuitry to be susceptible to excessive leakage
Wow. I'm surprised they made such a simple manufacturing mistake.
"Real-time clock circuitry"? Hmm.
Do you think that they have an onboard reference clock-generator now?
Maybe the rumors are true, that the 9xx chipsets will have some sort of "anti-overclocking" tech. in them. (Intel does have a patent on a method to block overclocking, based on a second independent clock reference source.)
I thought that all of the threads talking about not being able to overclock the 915 chipset, were based on a mistaken interpretation of the fact that the "performance enhancements" (PAT version 2) of the 925, would be more fully locked-out on the 915, avoiding what we've seen with the i865 with "PAT" matching up to the i875 chipset in terms of performance. (The silicon is actually the same, as I understand it. Just a speed-bin that Intel charges more to OEM mobo makers for the i875.)
While that may in fact be true, this new news does lead one to wonder if Intel is in fact going to implement strict anti-overclocking tech. This seems all the more ironic to me, having heard news a few months ago that Intel was looking into implementing a "system driver", kind of like NVidia, to allow overclocking of their chipsets and/or boards.
Wouldn't it be rather ironic, if Intel actually has implemented anti-overclocking tech, to prevent 3rd-party mobo makers from allowing OC'ing, but then on Intel's own "enthusiast" line of mobos, allow overclocking? Thus cornering the enthusiast/overclocker market all to themselves? Intel's no stranger to monopolizing markets, I think that we all know that.
Food for thought.
Edit: Here's a quote from the article:
Andrew Root, an analyst for Goldman Sachs Global Investment Research in New York, reported that only a small number of chip sets were affected, a number that was confirmed by an industry source. "As we understand it, the problem had (past tense because now appears fixed) to do with current leakage in the chipset's [real-time-clock] feature, and was encountered in certain printed circuit board designs," Root wrote in a note to clients Friday. "Intel's own?brand motherboards did not appear to have this issue.
Interesting to note that Intel's own boards didn't have this "issue", only 3rd-party OEMs.
