Pentium IV Non-bus Master PCI Bug Lives
Barbarian writes "This ZDNN article says that a bug in the Pentium IV chipset that caused a recall months ago and causes a slowdown on systems with a second (PCI) video card still exists. A talkback comment points out that this bug affects any non-bus master PCI device." To be fair, the probable amount of people that it will effect is relatively small, and even if you do want two monitors, most companies are just using the Matrox G450, or one on the AGP, one on the PCI.
states that the number of bugs in a chip design will double even 2 revisions.
Like the subject suggests.. its not just vid cards affected... is ANY card that has a LOT of data flowing through it...
I feel that, that makes the bug a little more serious than your standard Intel screwups...

CNET's News.com had a story on this as well:
Minor bug lingers in Pentium 4 chipset
Interestingly enough, they originally had it under a very misleading title (it said "Minor bug lingers in Pentium 4 processor" IIRC). They apparently got enough feedback that they retitled it by this morning.
Tell me: just how many people out there NEED a second graphics card?
I'll tell you what... two monitors are the way to go. Anyone who's going work that requires a lot of screen real estate (programmers, artists, etc) can benefit from an extra monitor, no matter how big their primary monitor is. Also, a lot of people simply have extra, perfectly good, compatible hardware laying around they'd like to use. Or they can pick it up on eBay or a computer show...
but given today's cheap 19" and 21" monitors running 1600x1200 resolution, you can have lots of display area AND still keep the menu commands on the same screen.
Trust me... in order to get 1600x1200 resolution at a decent clarity and refresh rate that doesn't kill your eyes, you need to buy a pretty nice monitor, NOT a cheap one. The average 19-inch monitor is NOT usable at 1600x1200... cheap ones only do 60 or 70hz at this resolution. Trust me, I did a lot of shopping before I found one and it wasn't cheap. But I love my 19-inch Sony. :)
In short, the bug with the i850 chipset only affects people who primarily use legacy hardware. It's not that likely people will put in older graphics hardware into today's P4 systems given how good 3-D graphics cards and their ability to display 1600x1200 32-bit color have become.
Wrong! A large number of computer professionals/hobbiest have old PCI video cards and smallish monitors laying around. Come on, what computer junkie DOESN'T have a box full of old hardware? :) It's INCREDIBLY USEFUL AND COST EFFECTIVE to use this old hardware for a secondary display on your shiny new PC.
And anyway... your post bothers me on a couple of other points to. The "who really needs all that screen real estate" attitude reeks heavily of the infamous "640k should be enough for everyone" quote. Also, it's none of yours or Intel's god damn business HOW much screen real estate I need. I pay for hardware, it should work whether you think I'm using it in a dumb way or not. If I think I need 3 1600x1200 monitors that's my business. Intel's hardware should simply work the way it's supposed to. If it did, we wouldn't be having this discussion.

It is the CHIPSET with the bug. Not the Pentium IV chip itself.
The problem is, if my understanding of "Video and graphical data" that they are referring to, this is more than just dual monitor systems. This also means that the whole raft of high-end video editing systems are going to have problems. And perhaps DVD decoder cards, too.
I suspect that the major issue here is that Intel doesn't want to do a recall on the boards that have already been made, like the i820. So they are figuring that this isn't a major enough problem, so they are going to just let it ship.
It doesn't bother me because I'm not going to buy a P4 of this vintage. If I upgrade, it'll either be to a fast P3, the next version of the P4 and chipset, or an Athlon.
