Plus the low-end HTPC targeted nvidia and ATI cards aren't exactly costly if it really bothers you that much.

Intel 6Gbps ports are fine yes. The Marvell is just another SATA controller; it's connected to the system via a PCI Express x1 link. The arguable difference will be in driver stability/performance/support. I don't think the Marvell chips function well under Solaris, for instance, but Intel works fine. Zhentar posted:It's in the IGP output, not the decoding. Oh, well, yeah that does kind of suck, then. I know my dad's projector (JVC RS-1) seems to only like 24Hz input. One dropped frame every 2.5 minutes, not a biggie, but as you said, I'd just do a low power discrete card (Nvidia most likely). Also, thread title is amusing considering you can't use IDE drives with your board unless you sprung for the quasi-deluxe model that throws some PCIe IDE controller onboard, heh. movax fucked around with this message at 22:35 on Jan 31, 2011 |

And if my search is correct, the 'fix' isn't really a patch it's just a suggestion to disable UAC, and it only applies to Sandy Bridge, not Clarkedales. If you can't see judder be happy you can't. Maybe it's because I work with video every day and know what to look for but it basically made it a non option to me. The big deal about this was that this was like the fourth time that a integrated platform was supposed to be the HTPC killer component and something about it hosed it up. 780g couldn't do 7.1 sound, 8300 can't handle 1080i, and Intel has floated on not being able to accelerate what was promised, to not being able to play without judder. LastCaress posted:gently caress, bought my asus p8p67 deluxe last friday :\ Read somewhere that boards made before jan 9th were not affected? There's still hope. January 9th is the original ship date for Sandy Bridge. They pointed it out to make sure people knew they were talking about that and not Clarkedale. If you got it early you still are affected.

frumpsnake posted:60Hz is actually 59.94Hz and by extension 24Hz is 23.976. You divide by 1.001. Yeah but unless you have a CRT how are you going to be seeing that? Take your average LCD and it just runs at actual 60 hertz, not 59.94. About the only LCD panels that actually refresh at 59.94 are old SD-only LCD TVs. Your computer monitor is refreshing at fully 60 hz anyway, so there's always going to be lost frames. Combat Pretzel posted:All proper 24p content is actually 23.976fps.

Most good TV shows are shot on film, esepcially in the 60s-90s before all digital.

Didn't someone on here (I think it was Sebrenica Surprise) mentioned that new platform launches come with motherboard and bios glitches and quirks? This is more than just a "quirk" so now I don't feel so bad not upgrading to Sandy Bridge and upgraded my defunct video card instead. A friend of mine ordered parts for a Sandy Bridge system a week ago or so but hasn't built it yet because he's waiting on a P183 case so should he wait to see if he can get a replacement for his motherboard? I believe he ordered the ASUS P8P67 Pro ATX board but I'm not sure.

This wasn't exactly what I meant but yeah. The Lynnfield launch was a good example of the more minor issues: basically everybody had been recommending Gigabyte P35/P45 since forever, and I think one of my early posts in the old parts picking thread was a list of all these reasons why you should buy a Gigabyte P55-UD2 or whatever over equivalent P55 boards. Turned out that while the overwhelming majority were okay, some people with different RAM ended up having memory compatibility issues and HOTS was full of people with new i5 750 builds that were all hosed up. P67 launched pretty well with regard to weird board-related quirks but nobody buying this early should expect completely smooth sailing. That said, I'd rather have to plug my drives into the SATA 6gbps or Marvell SATA slots instead of 3gbps than have to return my motherboard or RAM to NewEgg, get hit with a restocking fee, and pick another, so I guess it's progress.

Anandtech just posted another article with even more details of the defect. Due to a design error, part of the PLL for the SATA300 ports is receiving too much voltage, leading to it burning out. This failure will occur over time, and will be accelerated by increased voltage and/or temperature.

At 1 frame per 2.5 min you watch 10 minutes and you've got a 17% drift, which is noticeable by almost anyone. Most Blu-Ray content is 1080p24.

Can you know for certain whether you have or have not experienced the issue yet? Think of it as like a slight glitch in frames every couple of minutes or so (at least with their fix) in straight 24p it happens every 20-40 seconds however. Anyhow, if you really want to understand it look up judder on google, but keep in mind once you know how to look for it and you find it, you'll probably notice it from here on out.

My 3 year old Samsung A650 has a 24P mode, even though it's a undocumented feature that will only show up if the device tries it. The thing is, 23.97 or 59.94 is the correct standard. when NTSC was started for the first couple of years it was set to 60hz, but then lowered to 59.94 due to issues of getting hardware that could lock on to that exact speed. it was a tolerance concession. Anyhow, people have just shortened it to 24fps or 60fps for clarity, so any monitor, NTSC, ATSC or computer monitor should take either with ease.

Generally the gate of a logic transistor is going to be at 0 or the supply voltage (ignoring the leakage from the previous stage) so I don't see where bias comes in. Also, shouldn't large blocks of the chip have the same supply voltage and same gate oxide thickness?

Can you show me where it says all the monitors out there marked at 60 hz actually run at 59.94 hz because I mean you'd think it would at least note that in the back of the manual. A decade old CRT SDTV runs at 59.94 hz yes but the only LCD device I've ever seen that ran at that was one of the first generation of cheap SDTV LCDs.

Put simply, digital displays and videos have been hosed from their inception. Gamma only exists as a compensation factor for analog CRTs, specifically as a factor to compensate for the input-output characteristic of CRTs. Hollywood decided on 24fps (23.976, it is 24fps colloquially), gently caress everyone. TV decided on 30fps (29.976fps, 60 fields/second), gently caress everyone else. Now you need a display that can display both of these framerates (and 25fps in PAL land). And also handle interlaced/progressive content. And do it all perfectly. Thus show up such evils as pulldowns (+ telecine), 120Hz and many other myriad technologies that claim to do their job. All consumers want is to be able to watch the latest lovely episode of Survivor and the latest shitpile of a rom-com on their TV they bought with their tax refund without any juttering or other issues. e: I suppose that goal is achievable for most people, but if you're a video geek, work with video regularly (like an above poster mentioned) or are just generally more observant than average, these types of errors will come smack you in the face. And I don't think that 17% figure is right unless I'm missing something...

Yeah, I was thinking relative to the total frame rate, which was wrong. With professional monitors, you can get drift if you don't set the frame rate to match the monitor's capabilities, and also if you set your timeline settings different than that of the media. I see this issue often with our students. The end user will probably never see a difference, but to the trained eye, you do notice these things.

I ordered an ASRock P67 on Sunday and it shipped. At least I get to use it until March, and the board has 4 SATA 6 Gbs ports. I really hope the recall isn't handled poorly. It would be a huge pain to go through a normal RMA process in March. I think I would almost rather deal with four dead SATA 3 Gbs ports than tear my computer apart and wait 10 days for a replacement.
