Tweaking the garbage collector (for techheads only)
Bewarned: this post has to do with a technical, hidden process in your WoW client, something involving how your computer's memory is used and how you might be able to make it a little faster. But if you're not interested in the technical side of things, don't worry: this post is extremely skippable. The upshot is that while you can download an addon right now to possibly make your memory usage a little faster, the same functionality is coming to the regular client in 2.3. So feel free to move on to the next post if that's all you wanted to know.If you're still reading, you probably know by now that we're talking about garbage collection. Cladhaire has a well-written thread started in the UI and Macros forum that goes over exactly how garbage collection works in your computer's RAM-- after Burning Crusade, the WoW client uses a process called "incremental garbage collection," which dynamically deallocates memory as it falls out of use within the application. The problem, as I understand it, is that sometimes the memory won't actually fall out of use, which means the garbage collector won't kick off, which means garbage will sometimes sit in memory for a while waiting to be collected. For those times, there's GCTweak, an addon which you can install that will occasionally force the garbage collector to do its thing. If you have really low system memory, this might help, but only slightly.At any rate, while this is interesting (probably moreso to those of you comp sci majors out there), it's really a nonissue-- Slouken confirms that exactly this functionality is being built into the standard client in 2.3. If you're really good at this technical stuff, GCTweak might let you tweak your system enough to pump out a few extra FPS on a lower end system. But if you don't know RAM from ROM, and can't be bothered with all this technical wackiness, just wait until 2.3, and you'll get this same functionality anyway.
Sony's PSP slim cracked open: there's more NAND in there?
It didn't take long after the release of Sony's slim PSP in Europe for some over-anxious individual to get inside of his new handheld, and while dissection pictures are always a treat in and of themselves, this splaying led to an unexpected discovery. After inspecting the motherboard and comparing it to boards from prior (read: not slim) PSPs, it was reported that the newest iteration features "66MB of NAND memory including spare data," which certainly trumps the amount found in its predecessor; additionally, Mathieulh mentioned that the "idstorage area is now fully encrypted." Check out a few more pics for yourself after the jump.[Via MaxConsole]
Up to 3GB of RAM in the Mac minis
Reader John L kindly dropped us a tip that Other World Computing has upped their Mac mini memory upgrades up to a whopping 3GB of RAM. And in fact, if you really want a Mini that flies, they'll even squeeze 4GB under the hood, even though they say the Mac Mini can't really handle that much.The performance testing they did just completely confounds me, however-- in situations where lots of memory was needed (the "RAM Hog" setup), 4GB clearly beats everything else. In fact, in most of the regular testing-- the Photoshop test and the "Stress Test" the memory runs exactly how you'd expect: more memory means quicker processing. But in the last two tests, the Halo test and the Xbench test, the mini actually ran faster at just 1GB (which is what it ships with) than the 3GB, and almost as fast as the 4GB. The reasons for that are probably technical (too technical for me, although I'm sure our talented commenters have some answers), but it seems that in some situations, extra RAM just doesn't help.Still, in situations that ask for a lot of memory, having more will definitely give you a nice bonus in speed, and it looks like the mini can now hold more than ever. When I buy mine (in October when Leopard drops, assuming Steve lets it live that long), I'll probably just double it to a reasonable 2GB. But if you want that extra power, it's good to know it's there.
OCZ intros 1800MHz DDR3 RAM modules
OCZ is upping the DDR3 RAM ante yet again, besting its own recently introduced modules with its new 1800MHz PC3-14400 modules. Apparently the first modules of their kind to go into production, these will be available in both single 1GB modules and 2x1GB dual channel kits, with 'em boasting a peak bandwidth of 14400MB (or 14.4GB) per second and latencies "comparable to the fastest offerings of DDR or DDR2." Otherwise, you'll get OCZ's proprietary platinum-mirrored XTC (Xtreme Thermal Convection) heatspreader to keep the modules cool, along with a lifetime warranty for a little extra insurance.[Via The Inquirer]
iPhone / iPod to consume 25% of global flash memory output?
C'mon, don't act so shocked -- you had to realize that these record sales of NAND-based iPhones and iPods were using up some serious flash memory, right? Turns out, Apple's two biggest hits are "expected to consume 25-percent of the global flash output," which could in turn drive up prices of said memory in the not too distant future. DRAMeXchange, a market research company out of Taiwan that tracks the memory industry, further suggested that it could take "about two to three quarters before manufacturers can raise their chip yield rates to a higher level," which doesn't bode well for anyone hoping to see a price cut on any of Apple's handhelds due to increased volume purchasing in the memory department.[Via CNET]
JEDEC finally unveils official DDR3 standards
Rest assured, this isn't the first (nor the last) time you'll see products launch before the official specs get ratified, but JEDEC is doing the honors today by introducing the DDR3 (Double Data Rate 3) memory device standard. Key improvements that were noted include a 1.5-volt power supply, increased operating temperature range, memory device reset, burst chop, dynamic on-die termination, output driver calibration, and write leveling among others. The standard is reportedly intended to operate over a "performance range from 800 to 1600 MT/s (million transfers per second)," and while we certainly appreciate the details finally coming forward, the bevy of product launches from months past sure dampened the thunder.

OCZ announces PC3-8500 and PC3-10666 DDR3 RAM modules
Don't look now Kingston, but OCZ is already going mano-a-mano with your DDR3 offering by introducing PC3-8500 (1066MHz) and PC3-10666 (1333MHz) RAM modules of its own. Designed to play nice with Intel's Bearlake chipset, the noticeably flashy DIMMs will be offered initially in in 2 x 512MB and 2 x 1024MB dual channel kits. The Gold DDR3 modules will sport the outfit's proprietary gold-mirrored XTC (Xtreme Thermal Convection) heatspreaders for boosting their heat dissipation abilities, and as with other premium products from OCZ, these too come with a lifetime warranty. Interestingly, the company claims that these are currently available but in "limited quantities," which means that you'll probably want to hold up on busting out your credit card if at all possible.[Via TGDaily]
Kingston planning to reveal DDR3 HyperX RAM at Computex
Last last year, Kingston unveiled its then-blazing fast HyperX DDR2 RAM modules, and just as you're finally paying those couple of 2GB kits off, the same company is apparently planning to up the ante. Reportedly, Kingston is looking to reveal its 512MB / 1GB DDR3 1500MHz HyperX and DDR2 800MHz low latency memory modules at Computex, which should play nicely with Intel's DDR3-friendly Bearlake chipset. The DIMMs are expected to be "nearly twice as fast (over 20Gbps) as today's highest speed DDR2 counterparts," and the lower voltage (1.5v compared to 1.8v) claims to provide a "more efficient memory solution for both mobile and server platforms." Of course, pricing and availability deets weren't fleshed out just yet, but the second week in June isn't too far away.[Via Gizmag]Update: Despite statements to the contrary, Kingston pinged to say it's not debuting any SSD drives at Computex! The nerve!
Samsung builds a better, smaller 4GB DIMM
OCZ may have recently laid claim to the title of some of the world's fastest RAM, but Samsung seems to have found room to do a little boasting of its own, trotting out its first 4GB DDR2 DIMM based on WSP (or wafer-level-processed stacked package) technology. According to the company, that process not only makes the module smaller, but faster and more energy efficient as well. Not so clear, unfortunately, is what effect the seemingly cure-all technology will have on pricing or availability, with no word on either from Samsung as of yet.[Via PCLaunches.com]
OCZ intros "world's fastest" 1200MHz PC2-9600 Flex XLC RAM
Champs don't stay that way long in the computer hardware biz, but one way to ensure that the crown stays in the same camp is to one-up yourself before another firm can beat you to the punch. OCZ seems to be feelin' said mantra, as the company's latest Flex XLC RAM overtakes the previous rendition to claim the "world's fastest" title at 1,200MHz. Of course, we've seen quicker memory stuffed onto graphics cards, but the new motherboard-ready PC2-9600 Flex XLC modules sport a svelte hybrid cooling system that melds passive air and liquid injection systems to give you all the bragging rights you'd ever need. The DDR2-1200 modules are currently available in 2GB (2 x 1,024MB) kits, come with a lifetime warranty, and will run you right around $250.[Via Gearlog]
Just What is Wired Memory Anyway?
If you've ever opened up your Activity Monitor and looked at the System Memory tab, you've no doubt seen something similar to the above. But if you're like me, you've often wondered just what the labels mean. Just what is wired memory, anyway? Well Alex at Bits about Bytes has a nice little article explaining just what those labels mean, how different applications (particularly virtualization tools) affect memory usage, and how to figure out if you need to add RAM to your system. Oh yeah, and wired memory turns out to be memory "used by the OS [which] is pretty much untouchable. Another application can't 'borrow' wired memory." Good stuff.[Via FreeMacBlog]
Samsung's GDDR4 graphics memory goes to 2000MHz
While Samsung has been dabbling in the RAM world quite a bit of late, kicking out the micro-sized OneDRAM and cellphone-bound gigabit-density DRAM, the firm is now officially loosing its 2000MHz GDDR4 RAM on the world. While the zippy memory is already found on ATI's Radeon X1950 card, it'll now be available en masse to graphics card producers in order to speed up current and future offerings "by up to 66-percent." By using 80-nanometer production technology, the memory boasts a 4Gbps throughout, which is nearly two-thirds higher than the widely used 2.4Gbps GDDR4 variety out now; additionally, it'll be offered to vendors in just a 512MB density, rock a 32-bit data bus configuration, and utilizes "JEDEC-approved standards for signal noise reduction to help attain the highest possible speed." No word on how much Sammy plans on charging speed-freaked manufacturers, nor how long it'll take for a kilowatt-burnin' card other than the X1950 to include such a luxury, but we wouldn't count on it being too much longer, regardless.[Via TGDaily]
The Boy Genius Report: Cingular shows its cards
There's something about a carrier pricing sheet showing unreleased models that just gets the hair on the backs of our necks standing on end. Some of these are well, well scooped at this point -- the black and gold Motorola V3xx, Nokia N75, and the Samsung SYNC all gussied up in blue -- but what's new to us are the Samsung "Cardinal" and Nokia "Ram." We haven't the foggiest what these might be, but we can tell you that the Cardinal will go for $230 commitment free or $80 after signing away a couple years of your life, while the Ram will run $210 and $60, respectively. Could it be that Nokia's threat to start naming its phones has some teeth?
Speculation: Nvidia looking for eDRAM engineers; PSP2 on the horizon?
Sony and Nvidia have been friends for quite some time. While AMD provides the graphics technology behind the Xbox 360 and the Wii, the PLAYSTATION 3 is powered by Nvidia. Considering their partnership, Sony fanboys pay close attention to new moves that Nvidia makes. It appears that a recent job listing calls for a senior eDRAM design engineer, which is used extensively in video game consoles (including the PSP). The chances of a new eDRAM product to be used in a PC is slim, increasing the likelihood that a new video game product from Nvidia is nigh.Considering Nvidia's exclusive relationship with Sony, any new video game product coming from the studio will most likely be an extension of the PlayStation brand. Considering how the PLAYSTATION 3 just came out, it seems unlikely that they're actively designing the PS4. Is a redesigned PSP, or a successor to the PSP, in the works? ps3gamer14 from the 1UP boards makes a good argument for it, but until we get more concrete evidence, this is simply speculation, at best.
$300,000 worth of Hynix DDR RAM modules hijacked
It seems the traditional method of acquiring goods -- you know, that "money for product" approach we've been testing out for centuries -- is going to the wayside quite often these days, as yet another major heist has gone down in Taiwan. Twenty boxes of Hynix Semiconductor DDR RAM modules were stolen yesterday, as a trio of assailants reportedly used a machete and stun gun to threaten the driver. The hijacking is likely a planned, organized move, as reports say that the thieves were seen headed to the airport, where they probably hopped a flight to China. Interestingly, it was stated that "ownership of the chips is still unknown," a fact that's sure to make insurance companies drool, considering the $306,000 of missing goods that somebody is going to be out for. Incidents like this do wonders in making those $169 GPS / RFID adornments seem fairly inexpensive, eh?[Via Inquirer]
Samsung develops 1Gb synchronous DRAM module
Apparently, Samsung has been on quite the rampage (ahem) lately, busting out its new Powerhouse Fusion memory, working with NEC in hopes of crafting a one-terabit chip, and now announcing the industry's "first gigabit-density mobile DRAM" module. Using 80-nanometer process technology, the 1Gb synchronous DRAM module claims to be "more cost effective than other high density mobile solutions," and requires around "30-percent less current" than the double-die stack chips commonly used today. The monolithic chip introduces a new "temperature-sensing feature" that purportedly maximizes the "self-refresh cycle" to reduce power drain in standby mode, and also touts a 20-percent decrease in thickness over its predecessors. While we've no idea how much these modules will bump the price of your future gadgetry, they should begin finding their way into "handsets, digicams, PMPs, and handheld gaming machines" in the second quarter of 2007.[Via Physorg]
The fix is in: Another Samsung exec falls in DRAM conspiracy
The fifth Samsung executive has agreed to a 10-month prison sentence, pleading guilty to conspiring with other companies to fix DRAM prices. Since 2003, the ongoing U.S. Department of Justice investigation has charged four vendors in the scandal. While Samsung already pleaded guilty and was fined $300 million a year ago, this latest plea relates to OEM price-fixing over 2001 and 2002; if you bought a computer from Dell, HP, Gateway, or Apple, those companies likely passed the extra costs on to you.Once a product becomes a commodity -- like RAM -- the pressure for collusion seems to rise because price is the main product difference; all vendors lose in a price war. We don't think that video cards and GPUs are interchangeable like RAM, but is the graphic industry using similar tricks?See also:Uh-oh!

Samsung unveils Powerhouse Fusion memory, dubbed OneDRAM
Being that Kingston went and introduced its own blazing fast DDR2 RAM, Samsung's hitting back by announcing its Powerhouse Fusion Memory Solution, dubbed OneDRAM. But Samsung's not gunning for the gamer's wallet necessarily, as its new device is specifically geared towards "handsets, game consoles, and other digital applications such as 3D graphic work." By taking a "dual-port" approach, the RAM "sharply increases" the time it takes to transfer data between processors, not to mention reducing power consumption by 30-percent. Moreover, Samsung claims that "a single OneDRAM module can replace at least two mobile memory chips in a high-end smartphone," further stating that "five-fold" speed increases were realizable in cellphone response and gaming console operations. While we're not sure how much Samsung plans to charge cellphone / console manufacturers for this snazzy new module, you can expect to see handsets loaded with OneDRAM "by the second half of 2007."
Kingston unveils blazing fast HyperX DDR2 RAM modules
While Kingston's no stranger to the memory world, the firm is easing off its portable solutions to focus on the release of two new DDR2 modules, presumably in conjunction with AMD's most recent processor announcements. The RAM giant has announced mass availability of the speediest modules around with its new PC9200 (1.15GHz) and PC9600 (1.2GHz) HyperX offerings. Part of the gaming-ready KHX series, these speedsters both sport CAS latencies of five and are available in 512MB / 1GB sizes. Although Kingston recommends an AMD CPU "for optimal results," we're sure Intel chips will find a way to get along as well, and the firm even burns them in for 24 hours to prevent any DOAs. The KHX9200D2 modules can be had individually for $137 (512MB) or $259 (1GB), or in kits of 1GB ($273) or 2GB ($518); the flagship unit will run you $139 for 512MB, $263 for 1GB, and kits are available in sizes of 1GB for $278, or 2GB for $525.
OCZ kicks out liquid-cooled PC2-9200 FlexXLC Edition memory
Sure, liquid-cooling your gadgetry is oftentimes done to prove your 1337-ness, but in cases like Apple's oh-so-toasty Dual G5 PowerMac and Microsoft's notoriously warm Xbox 360, we consider the task quite appropriate. In OCZ's case, however, we're leaning towards the unnecessarily flashy side, as the company's PC2-9200 FlexXLC (Xtreme Liquid Convention) Edition memory touts both air and water cooling possibilities. Dubbed the "world's fastest DDR2 RAM" at 1,150MHz, the modules feature an eight-layer PCB which hinders crosstalk and improves signal integrity, and sports a "fin-like heatsink" to waft warmth away from the components. Moreover, it also boasts liquid-dispersing units that pass water across copper lines to cool things off when taxing your system. While we're not sure how much this showstopping memory will run you, it does feature a lifetime warranty in case the liquid decides to boil over and create a bonafide disaster.[Via Electronista]
