i820 Chipset Under Recall

Dman33 writes "This Cnet story details how Intel hit another bump in the road with its i820 motherboards. This defect is in the memory translator hub which allows for the use of standard DIMMs as opposed to Rambus. Intel is planning on just replacing the standard memory with Rambus memory, but will replace the entire board at the user's request. " The estimated cost would put a big hurt on Intel's bottom line -- several hundred million dollars worth of it.

    Intel's engineers are humans too, they make mistakes. ... Oh, and for all you RDRAM hatemongers: The problem has nothing to do with RDDRAM; the memory controller used in specific motherboards was not shielded properly, causing intermittent lockups.

    But RDRAM is the problem, insofar as Intel is ramming it down their engineers' and customers' throats with no regard for reality. Intel management has committed so strongly to RDRAM that they'll practically have to commit seppuku before changing their "strategy". They ought to have looked at RDRAM's risks before committing.

    I agree that RDRAM can be made to work. But the reality is that RDRAM has numerous challenges:

    RDRAM's 800 MHz frequency (with strong harmonics up to at least 4 GHz) takes highly skilled designers, especially for the PCB. It's one-third the speed of a microwave oven, fer chrissake. A recent article in (IIRC) Electronic Design showed off a 25 GHz oscilloscope for doing RDRAM design work. Few EEs (me included) are skilled at those frequencies, where every wire behaves like an antenna, and where measureable amounts of the signal are dissipated by dieletectric losses. RDRAM is a brand spanking new architecture. There were no off-the-shelf designs and no industry experience with it. It would be like Ford Motor Company suddenly deciding to put rotary engines in all their cars: a recipe for unlimited risk. Intel apparently told their engineers "RDRAM only from now on", leaving them with no ready substitute if RDRAM should have growing pains. The memory translator hub debacle is an shining example of poor risk management.

    I'm not knocking the RDRAM concept itself, just Intel's Dilbertian implementation of it. In fact, I think narrow superfast busses are the Wave Of The Future(tm). Imagine buying an extra 16 gigs of RAM, taking it home, and plugging in the optical fiber without turning the machine off. Ditto for hard drives, or monitors. Would be much easier, especially for the average person.

  2. Trivial to fix by Anonymous Coward · · Score: 4

    This defect is in the memory translator hub which allows for the use of standard DIMMs as opposed to Rambus.

    Why can't they fix with the good ol' fashioned method of "reversing the polarity of the positron emission trail" or "modifying the deflector shield harmonics to emit a resonance"?

    I mean, what is the problem! Are these people stupid or something?

  3. Have they placed a limit on the RAM replacement? by Johnath · · Score: 4

    It strikes me that intel's in a dilly of a pickle if they plan to swap regular pc100 dimms for rdram. What's to stop a person from claiming (maybe even legitimately) that they needed 2G RAM on their new mobo? Go out and spend whatever it'll cost for 2G of pc100, and then let intel swap it up to rdram? You'd make a killing!

    Another application would be to buy several of these, as needed. Buy a boatload of ram for one, and when they replace it with rdram, use that to feed the others.

    They weren't kidding when they talked about damage into the hundreds of millions. That rambus investment is starting to look more and more painful for intel shareholders.

    Intel's engineers are humans too, they make mistakes.

    The problem is, this isn't solely a symptom of Intel's engineers goofing... Intel has been trying to get Camino out the door for quite a long time now (I believe the first publicly announced roll out date was more than a year ago). If they can deliver millions of CPU's (which are arguably much more complex than a memory controller) why then, can't they deliver an 820 that works. Remember, this is a company with billions of dollars to spend and thousands of the brightest minds in the industry... They ought to be able to deliver a memory controller that works in a reasonable amount of time.

    This latest 820 debacle is more of symptom of political infighting and a company collapsing under its own wieght. There's an awful lot of 'us vs. them' infighting between the various processor and chipset marketing/design teams. Trust me.

    Just like they replaced all those Pentiums with the FDIV bug

    ...but only after a tremendous backlash from customers after Intel told them that Intel's engineers would decide on a case by case basis who would, wouldn't get replacments.

    The problem has nothing to do with RDRAM

    ...excpet that it has EVERYTHING to do with RDRAM. Camino is an RDRAM memory controller, right? So... I don't know how you could say that this has nothing to do with RDRAM.

    So please, guys, cut Intel some slack here.

    No... they don't deserve it. They've screwed countless customers (think Dell and many other OEM's) with promises of Camino based motherboard delivery, and every time, they've managed to screw it up. Dell has taken it in the shorts for several quarters now due to Intel's inability to deliver Camino and Camino based motherboards. I'm no great lover of Dell, but its fortunes shouldn't be based on (or ruined by) the ineptness of a monopolistic supplier. Expect the governement to start looking at Intel again before too long... I do.

    I remember Andy Grove once saying that Intel's biggest enemy was itself.... That's looking more true everyday.

    Don't believe Intel's hype, and don't feel sorry for them. They work their engineers and production workers VERY HARD and VERY LONG for relatively low pay (like I said, trust me) and make up the difference with stock options. Well, if the company, as a collective, performs poorly (as Intel has over the past year and half or so), alot of the compensation that comes in the form of stocks options will devaluate and Intel's talent will look elsewhere for a company that can manage its own complexity and avoid political infighting an turf battles.

  5. Why waste time with RAMBUS? by gfecyk · · Score: 4

    RAMBUS is an expensive joke! The i820 can't even keep up with the "old" 440BX based solutions. Have a look at a March 8th article that goes into all the gory details. To quote Mr Pabst: "Rambus seems to be a rather nasty disappointment."

    Not everyone will want to overclock a 440BX board to 133 MHz, but since so little hardware is actually overclocked, and even then only by 30%, you stand little chance of ruining anything. Just make sure you use a CPU and SDRAM rated for 133 MHz FSB.

    If anything, wait for i815 to come out. This is supposed to be the "real" successor to 440BX.
