bit-tech.net - The Dark Side of Overdrive

  • Faster is always better. Thanks to that simple philosophy, LCD pixel response times have been driven down to puny proportions in recent years.

    Today, even the slowest panels are rated at 16ms or better and deliver adequate response for all but the most fanatical PC gamers. High performance screens, meanwhile, now trade low single-digit millisecond blows in the battle for fast response dominance.

    That’s the good news; the bad news is that the quest for ever lower pixel response times comes with a pair of undesirable side effects: input lag and inverse ghosting. Superficially, the two appear to be unrelated, but they share the same underlying cause. The culprit is a response-enhancing technique known as overdrive.

    Also common to both input lag and inverse ghosting is a rather murky cloud of controversy. Some sneer at the idea that input lag even exists, while others argue that while it may exist, only pedants with a penchant for pointless whining could possibly notice it.

Opening WHR-G125

  • Take Apart Your Buffalo WHR-G125 Router
    Pop it Open to See What's Inside

    Opening the router may void your warranty. Unlike Linksys WRT54G the WHR-G125 has no seals to break in order to open the enclosure. I don't understand how Buffalo would even know that the router was taken apart if that ever came up during a warranty claim.

    You will need two precision scredrivers to pry the sides and one T9 size hex star screwdriver (torx) to remove a single screw.

Buffalo WHR-G125 External Antenna

  • Add External Antenna to Buffalo WHR-G125
    Increase the Router Range with an External Antenna

    Buffalo WHR-G125 comes with a stock antenna permanently attached to the side. Some other routers like the popular Linksys WRT54G are equipped with detachable antennas that can be replaced with high gain counterparts. The "permanent" attachment in WHR-G125 is not so permanent after all. You can remove the antenna and install an external connector in as little as one hour

Buffalo WHR-G125, a possible replacement for WRT54GL for use with DD-WRT

  • A recent post on the DD-WRT announcements page reveals that a possible sucessor may have been found in the Buffalo WHR-G125. This model is just coming onto the market as a replacement for Buffalo’s previous WHR-G54 series and should be widely available via mainstream retail channels soon. The WHR-G125 has a lot going for it. It is inexpensive at a mere $46, contains 4 MB of flash and 16 MB of ram like the WRT54GL and features both a faster processor and a more modern, more sensitive WiFi chipset. There will also be a high power version of the product for $20-30 more, which contains an amplifier and detachable antenna, but is otherwise identical.

Linksys WUSB54G Antenna Connector

  • I was looking for a USB-connected WiFi-Adapter to keep the antenna-cable short. I chose the Linksys WUSB54G v4 because it is not too small to modify and uses a Ralink 2570 chip: there are GPLed drivers for Linux available.

    e. If your are playing with monitoring (kismet, airodump, etc.) or injecting packets (aireplay), you should check out the CVS version of the stable driver or a specially patched one at http://homepages.tu-darmstadt.de/~p_larbig/wlan/. These can inject packets and show the signal strength.

    But now on to replacing the included antenna with a universal RP-SMA connector.

daouid - WUSB54G Antenna Mod 1

  • My old pcmcia card fried, so i had to get a new one.
    I went for a WUSB54G adapter. It's a little plastic case, housing the WLAN PCB, that connects to PC using USB.

    The best thing about this adaptor is that since it is connected to pc using a USB cable you can add a USB extender without any signal deperdition. This allow placement of the device in a suitable place far away from your PC, witch in a way is interfering with the signal (metal case etc...).

Time to Put Off Buying LCD TVs and Displays - NYTimes

  • August 8, 2008

    The LCD panel industry is suffering from over supply and falling demand, and in this case, what's bad for Wall Street and stock prices is good for consumers.
    Nobody likes to buy an expensive new LCD TV or LCD computer display and then watch as prices tumble within weeks or months of the purchase. So buyers beware, that's exactly what could happen if the LCD industry situation continues to unfold as some analysts predict.

All Nvidia G84 and G86s are bad - The INQUIRER

  • THE BURNING QUESTION on everyone's mind is what Nvidia parts are failing in the field? No GT200 jokes here, NV personnel are still quite sensitive about that, but our moles have told us about the bum GPUs.

    The short story is that all the G84 and G86 parts are bad. Period. No exceptions. All of them, mobile and desktop, use the exact same ASIC, so expect them to go south in inordinate numbers as well. There are caveats however, and we will detail those in a bit.

Intel Atom to boost mini-ITX chassis

  • With Intel restricting its Atom processor to only be used with mini-ITX-based motherboards, mini-ITX chassis are expected to see a surge in demand in June, according to sources in the channel.

    In order to make a clear separation between nettop products and traditional entry-level PCs, Intel only allows Atom processors to be used with mini-ITX motherboards, limiting the platform with a lack of PCI Express and only a single DIMM slot for up to 2GB DDR2 memory.

Linksys WRT54GL Linux-based Open Source Firmware

  • Linksys found a place in many a geek's heart when it released the original WRT54G router back in 2003. A network router, 10/100 Ethernet switch, and wireless access point all rolled into one, the WRT54G blazed a happy trail as one of the earliest home networking devices to have its firmware source code made publicly available under the GNU General Public License (GPL). Soon after, a number of third-party firmware options became available, letting networking and Linux enthusiasts utilize their routers in ever more powerful and creative ways.

    Earlier this year, Linksys modified the design of its most recent WRT54G. They halved the amount of flash memory and RAM to just 2MB Flash and 8MB RAM and switched to a VxWorks firmware. According to Linksys, this change allowed them to decrease the memory footprint of the OS and reduce the hardware requirements while maintaining a similar feature set at a reduced cost.

    Carrying on the Linux heritage for enthusiasts is the WRT54GL, a device with essentially the same Linux kernel, 200MHz processor, 4MB Flash, and 16MB RAM as the old WRT54G v4. Since the majority of aftermarket firmware won't work on the WRT54G v5's crippled hardware, the WRT54GL is now your only Linksys option for third-party-compatible fun if you can't score an older model. It's the same story with the neutered WRT54GS v5, Linksys's SpeedBooster–equipped line that flaunts enhanced Wireless-G speeds.

Eight power supply units encounter The Beast - The Tech Report - Page 16

  • Conclusions
    We've covered a lot of ground today, stressing eight power supply units to—and in some cases beyond—their limits. With only a couple of exceptions, the PSUs worked as advertised. Each maintained DC voltages and AC ripple content within manufacturer-specified tolerances, and overall efficiencies were pretty close.

    That said, each PSU offers a unique blend of performance, wattage, features, and price. The sum of those factors elevate some models above others if you're looking to power an enthusiast PC. Below, we've summarized our thoughts on each PSU.

10 things we hate about laptops

  • Valerie Rice


    November 15, 2007 (Computerworld) Damaged. Lost. Stolen. Too big, too small. Insecure and unreliable. And just plain annoying. If you're in IT, there's just not much to like about laptops.

    To be sure, portable computers have changed the way business operates, so much so that we literally cannot imagine a work life without them. That said, IT professionals, whether they're dealing with accident-prone users or keeping the network secure, say laptops are nothing short of a support nightmare.

    Some cope by outsourcing support altogether (see To outsource or not at the end of this article); others by rigidly adhering to standards and trying not to personally take the hate mail they receive from disgruntled end users.

    Either way, IT executives have a lot to say on the subject of laptops, nearly none of it good.

    And that's ironic, or maybe just tough luck, because sales of laptops in the business sector are growing 20% a quarter,

AnandTech: ASUS: The EN7600 GS Silent, and EN7800 GT TOP Silent

  • The EN7800 GT TOP Silent follows the same design of the earlier released 6600 GT Silent for the most part. The card and heat sink are scaled up to accommodate the more powerful architecture, but the heat sink is basically the same with an odd-looking metal arm protruding from the top that swivels out 90 degrees. The 90 degree angle on the protruding sink positions it squarely over the CPU fan on our system, ingeniously using the air from the fan to aid in the card's cooling.


    While one of the strangest looking designs we've ever seen, the heat sink appears to be very effective at keeping the GPU cool, and we haven't experienced any problems at all with performance out-of-the-box.

Intel Pentium Dual-Core E2160 - The Next Overclocking Wonder hardwarezone.com

  • Overclocking the E2160

    As we highlighted earlier, what makes the Pentium Dual-Core E2xxx series so appealing is that this L2 cache constrained processor takes on all of the charming traits of the Core 2 Duo processors with the same processor microarchitecture. And with less L2 cache, this directly correlates to a nice price cut. Compared against the highly popular Core 2 Duo E6320 (the E6300's replacement at US$163), the Pentium Dual-Core E2140 / 2160 processors are 50% less expensive (US$70 and US$84 respectively) and the only differences are the slower 800MHz FSB operation and the 1MB L2 cache. So the burning question is of course the impact of the measly L2 cache. We'll leave you to find that out in our results segment coming up shortly.

    With the very small price delta between the Pentium Dual-Core E2160 and E2140, we preferred showcasing the former model for the following reasons: it is a 1.8GHz processor, similar to the Core 2 Duo E6300 model that we first overclocked a year ago, the higher 9x processor multiplier allows speedier CPU core clock increase when stepping up the FSB ladder than the E2140's 8x multiplier and thus negating the need of an overclocking-class motherboard as well as not needing high speed memory. As such, overclocking the Pentium Dual-Core E2160 should be easier as well as a less expensive affair than with the E2140.
