    Don't flash Vertex 3 SSD with OCZ's Linux CD if you have Intel RAID

    Just updated Vertex 3 from 2.15 to 2.22 using the OCZ Linux CD image. After rebooting, one of my RAID disks in my RAID5 dropped out of the array. Ok, fine, "huh? this must be a fluke thing" I thought. Rebuilt the entire array over 16 hours. Done, everything back to normal. Booted up again...

    Sleep works half the time?

    Oh geeze, really? Yeah, it's been overclocked. But once it fails to wake from sleep, the bios automatically resets back down to default clocks (which would be 333 FSB). Upon retrying sleep again without OC'ing again, it would still fail. However, it actually never worked for me until...

    Sleep works half the time?

    Hey everyone, I have a Gigabyte P35-DS4 paired with X3350. While I know that X3350 doesn't have S3 sleep state (or something) compared to its Q9X50 counterpart, I know I can put the computer to sleep fine. The problem is, when I wake it up, it will sometimes wake fine (half the time?)...

    Sound interference?

    Tried both the front and the back. Without and without extension. Different earphones/speakers. Same thing. :(

    Sound interference?

    On the hardware side, I only have one card installed on that motherboard, and it's the graphics card...so I don't know if it's IRQ conflict. On the software side, if it's IRQ conflict, wouldn't that mean only a thing or two would cause the interference to manifest, not, well, everything? As...

    Sound interference?

    Hey guys, I'm in the market looking for a new Z77 motherboard. One of the big annoyances with my current Gigabyte P35-DS4 is that I can literally hear the interference of devices on my machine. For example, if I move my mouse, I can hear a monotonic frequency on my earphones. When I click...

    Why does nvidia cheat so much?

    Definitely does seem like the tessellation is a "post" production process. Take the normal/parallax map and apply offsets to the highly tessellated underlying geometry. I don't see "issues" with that -- it's a simple implementation that has its own pros and cons. When this is applied to...

    Why does nvidia cheat so much?

    So, back to the original topic. After reading through the Tech Report's article, I have to conclude that the author is pretty ignorant about information theory and computer graphics. First of all, the quickest way to do fixed tessellation is to use the object's bounding volume's center or...

    MacOSX Graphics Drivers - who writes them?

    It's very possible that Apple is using some sort of interface code from nVidia/AMD. However, I doubt nVidia and AMD are writing Apple's drivers...yet. Remember the most "difficult" part about drivers isn't dealing with the hardware -- it's actually dealing with the OS/virtualization and...

    MacOSX Graphics Drivers - who writes them?

    It's easy for them, as in they know what needs to be done, and none of it requires tons of problem solving skills at or beyond their capabilities. What's not enticing is that it's really tedious work. To them, it's like asking, "Can you flip a burger for 16 hours a day? Yes? So do you want to do...

    MacOSX Graphics Drivers - who writes them?

    Apple used to write their own drivers. Don't know about now, but I suspect the same. They definitely have the expertise -- who else would code up the Apple-specific extensions for the iOS devices? That and it only takes one or two knowledgeable people to do it -- I even know a few that can...

    GTX580 - Video driver keeps crashing / recovering & video corruption

    My 8800GTS512 from eVGA has the same issue. It happens the most in SC2. I noticed that the fan never spinned up, even as the card reached 70+ (I know, that's pretty low). And after it reaches around 70 (this probably varies from card to card), I would crash out of SC2. This was pretty consistent...

    Next Gen XBOX to use AMD 28nm CPU/GPU Fusion chip - Rumor

    8800 series was launched November 8th, 2006, 3 days before the PS3 launched...and I don't think the 7950GT is as fast as the 8800?

    Next Gen XBOX to use AMD 28nm CPU/GPU Fusion chip - Rumor

    Hitting the same MMU or whatnot is very possible (since that's how the 360 is), but it's rarely useful, if not downright harmful, to be able to directly manipulate the GPU's register files. The whole reason why the GPU can be so parallel and fast is because it's decoupled from the CPU. If the...

    30" Monitors - HP ZR30w vs Dell U3011

    I just got the U3011 a few days back (the 25% off coupon, total came out to ~1200 tax included). So far I'm very happy with it. One issue I had was when I first turned on the monitor, I got this slightly green tint (I think it's green?). I was a little peeved...but after a minute, the tint...

    NDA for Cayman is lifted 22nd?!

    What's the possibility that the 6970 ships with a 512 bit bus? While it's not impossible to use higher density chips, but from past history ATi's default specs usually sticks with some sort of memory bus to memory size ratio, and allow the vendors to go above that. Of course, it's also entire...

    Civ 5 interview. First 'native DX11 game'

    To understand what multi-threaded DX drivers are, you have to understand what the underlying implementation is. So let's take a look at a modern game engine, DX implementation, and the underlying hardware. To start, the underlying hardware is a per-context command-serial hardware. As in, for...

    Nvidia for Better Or Worse

    Wow. I think I'm speechless. What does 30% market share of nVidia cards have to do with OpenGL and DirectX? This was a comparison between an "open" standard OGL vs. a "closed" standard DX, not between DX and nVidia (what? that doesn't even make sense). So, when did intel not have an OGL and DX...

    Nvidia for Better Or Worse

    If we're talking about the AA support on the pushbuffer level, then I think it's possible that nVidia did go out of their way to expose certain hardware commands for Eidos. That or he could've simply mistyped NVIDIA for Epic. *shrugs* On the other hand, who licensed UE3 tech doesn't really...

    Nvidia for Better Or Worse

    I don't think closed or open standards have that much impact on innovation. Take OpenGL for example -- it's open (input open to many in the public, voted by some board), yet it's slow in the innovation front. On the other hand, DirectX is closed (input given only to select people chosen by...

    The point of ATi's/nVidia's new video cards?

    I don't know about you, but I'm excited because I get to develop using the new features so that you folks can play them later. If AMD/nVidia don't release new hardware, I can't make revolutionary new features, and you'll be stuck with pretty much the same thing. It's like a classic chicken or...

    GPUs Will Have 20 Teraflops of Performance by 2015 ? Nvidia Chief Scientist.

    Not arguing against anyone's points, but x86 isn't going to die anytime soon. However, saying that Intel can deny nVidia from making x86 CPUs is a bit misleading. The fact is that the patent on the 32-bit x86 design has long expired (1985, even with the updated 20-year patent coverage), and...

    THE Hydra Demo

    Yeah, you're right. I should've looked further into the new stats on CUDA and some such. The bandwidth currently stands at about 2GB/s one can get off of the cards. Which means, for a 60fps game, that's about 33MB/frame. Which I still sincerely doubt is enough to synchronize between two cards...

    THE Hydra Demo

    I read the article (although I forgot most details already, since I read it yesterday) and I have to say, the images look pretty suspicious. If those truly ARE the output images of the two devices (as in, they're not illustrative images showing workload differences), then I call BS. The whole...

    is DX11 coming in 2 months?

    They're announcing DX11 this month. They're not releasing anything. I don't think they've even finalized the specs yet. Once they finalize the specs, the hardware that's in the design process will have to be adjusted to fit the final specs (the major graphics chip designers are all in the design...

    Thoughts On GPU Physics

    Yep. The fact that there isn't floating point divide on the Cell SPUs is one popular example. Haha! Yes, that's the first problem...the devs have to implement it to begin with. Although honestly, a lot of devs are using Havok Physics (not FX), especially in the console world. But this is why...

    Thoughts On GPU Physics

    Radiosity will not be the ideal. Since radiosity is only good for pure diffuse (inter-)reflectance, it has the inverted problem of ray tracing (where ray tracing solves specular reflections). Almost all (if not all) known material in the world exhibit both diffuse and specular reflectance with...

    Thoughts On GPU Physics

    I think we're all missing something very fundamental and important. This reason will be why Havok physics (that affects in-game state) will not go on to the GPU with the current generation (or even next and a few after that) of hardware. And what is that? It's floating point accuracy. AMD and...

    Any downside to running a Xeon processor?

    Sorry, spent all my time finding what the problem was with my machine (new machine). Finally got it stable (involved an RMA). But yeah, when I try to put it to sleep, all hell breaks loose. Sure, it goes to sleep fine...but when it wakes up, it's just like being woken up constantly by someone...

    Bad RAM and...high pitched squeal?

    So I recently bought a new computer and was testing my OCZ DDR2-1000 ram. I found out that I'm having lots of errors in the 8000-8192 range, all with the exact same error bits (0080 0000). So that's already quite unusual to begin with (I'm running at 450MHz FSB with 5-5-5-17 at stock 1.8V...I...

    X3350 / Q9450 Overclocking Thread

    Ah, sorry, didn't specify. But mine was a bump in the middle (instead of a dent). I'm wondering if putting additional padding on my TRUE120 would make it better. Since it can still sorta twist, I'm wondering if it's keeping the temps up.

    X3350 / Q9450 Overclocking Thread

    Running my X3350/P35-DS4 at 3.6 with 1.075V (at least, that's what RealTemp is reporting). RealTemp max running Prime95 is 64/60/52/58...which is kinda weird. I lapped my TRUE120 (with NF-P12), but didn't do so for the heatspreader (which is slightly curved). I also didn't add any additional...

    Any downside to running a Xeon processor?

    BTW, there is a difference between the chips. The gist of it is that there are no SLP#, DPSLP#, and DPRSLP# states on the X33xx series CPUs. That means, no sleep states. Not sure what that corresponds to in terms of the C0-5 states for Penryn, as on page 84 of the X33xx spec sheet shows HALT...

    Question about bios reported temps

    Hey gang, I'm running a X3350 (stock) on a P35-DS4 (with unknown firmware...and the board was ordered a few days ago from newegg...so whatever the revision is, I don't know) with a 2000-grit lapped TRUE120. I just popped in the CPU and had to leave for work. But I had just enough time to look...

    New 9800GTX Won't Fit!

    I have the Solo as well, and I just put in the same factory OC'ed EVGA 8800GTS 512. Actually, I bought the Solo a year ago, and never put anything in it. At the time, I was considering getting the 8800GTX when it first came out. But when I read about the length of the card, I went and measured...

    Nvidia 9600GT vs ATI 3850/3870 Power Consumption

    I think this has to do with that secret OC that some other website is claiming nVidia is doing. As you'll notice, the one where the 9600 is drawing more power is using an nVidia chipset, and the scores are also higher. This seems to match up with what this site is claiming. So I suppose it'll...
