Ack! Your smokin' fast Core 2 Quad processor and other Intel chips may suffer from what security experts call "CPU cache poisoning." Sounds nasty, and according to Joanna Rutkowska who discovered the security flaw, it is.
"In this paper we have described practical exploitation of the CPU cache poisoning," Joanna Rutkowska and Rafal Wojtczuk wrote in an abstract paper (PDF). "This is the third attack on SMM (system management mode) memory our team has found within the last 10 months, affecting Intel-based systems. It seems that the current state of firmware security, even in case of such reputable vendors as Intel, is quite unsatisfying."
Rutkowska and Wojtczuk go one to discuss proof of concept codes for arbitrary SMM code execution, which could (theoretically) lead to abuses of the super-privileged SMM mode and embedding SMM rookits. Doing so would (again theoretically) give hackers control over the affected PC. Worse yet, according to Jamey Heary, a consulting systems engineer for Cisco Systems, the hack would be "virtually undetectable."
So what does Intel have to say? "We are working with these researchers. We take this research and all reports seriously. Currently as far as we know, there are no known exploits in the wild," Intel spokesman George Alfs said in a written statement.

Zeebo, backed by Qualcomm, announced a new device it's calling the "fourth video game console." But don't worry if you're a console collector, the Zeebo console probably won't ever see the light of day in the U.S. and is instead being targeted at middle-class buyers in emerging markets.
Referring to the middle-class consumers of the so-called BRIC nations -- Brazil, Russia, India, and China -- Zeebo Chief Executive John Rizzo said "A console for these markets has got to be affordable."
To keep costs down and cut back on rampant piracy, the Zeebo will not use a disc or other fixed media, and instead employs a Qualcomm chipset to allow gamers to connect wirelessly to purchase and download games. The onboard flash memory can store about 50 games, Rizzo said.
Other specs include an ARM 11 / QDSP-5 running at 528MHz, 128MB of DDR memory, VGA (640 x 480) output, three USB 2.0 ports, and an SD card slot.
The Zeebo console will first be available in Brazil for $199, with pricing expected to drop to $150 within the year.
There’s a lot to be excited about when you consider the features Windows Home Server offers out of the box—primarily, automated backup of all your desktop and mobile machines and media streaming to every room in your house. HP builds on this goodness with a second-generation WHS product that boasts both improved hardware and a supercharged features list.
When we reviewed HP’s first foray into the world of Windows Home Server last year, we were optimistic about the future of the platform but a bit underwhelmed by the performance of the little box. Since then, the Home Server software has gone through some teething pains, including a horrific bug that corrupted users’ files (since corrected with the first Service Pack for the Home Server software).

The compact-style Eclipse sports an adjustable DPI up to 2400, whereas the larger Behemoth ramps up to 3200.
Bigfoot, the company behind the uber expensive Killer line of network interface cards (NIC), expands its lineup this week with the Killer Xeno Pro and Ultra cards. Both cards run on the PCI-E interface and purportedly offer better throughput than the company's earlier models. But the biggest selling point for the Xeno series is the integrated audio for hardware-accelerated voice-chat.
"Killer Xeno's voice-chat acceleration technology addresses the most requested gamer feature, and will enable the millions of online gamers worldwide who utilize these chat services to enjoy a 'hiccup-free' voice experience while playing the latest generation of online games," Bigfoot wrote in a press release (PDF). "Bigfoot, in providing voice-chat, has partnered with companies supporting leading products such as TeamSpeak and Vivox as well as utilizing the popular open-source application Mumble."
The Xeno Pro comes with 128MB of onboard RAM, while the Xeno Ultra upgrades to 256MB, while also adding a customizable onboard LED status display for caller ID, network statistics, game information, and customized messages. Otherwise, the two cards are share the same spec sheet, including an upgraded NPU, hardware bandwidth control, and a hardware firewall.
The Xeno Pro will be available in April for $130 from both Alienware and EVGA. The Xeno Ultra will be available in May for $180 on retail shelves.
The internet has been rife with rumors of an Apple netbook. Another unconfirmed report has joined this unabated procession of rumors. According to a report on the website of Smarthouse, a prominent technology publication from down under, Apple has a functioning netbook prototype.
The magazine’s source at LG, Korea also claimed that the netbook will be produced in Taiwan and will feature a LG OLED screen. But our abstruse friends at Engadget have pointed out that the author of this particular Smarthouse report, David Richards, has a history of fanning rumors bereft of any logic. So do take this with a pinch of salt.
Time for another price and parts guide! The $1000 parts guide we posted earlier this month garnered much discussion and debate among readers, so we wanted to a better job explaining our choices in this edition. Compared to the pricey decked-out systems from OEM builders like Falcon and Digital Storm, $1500 is still technically in the "budget" range. But for many people, that's still a lot of money to spend on a PC. We catered this build for gamers, and anchored our picks on the GPU and CPU, while judiciously choosing the other parts and brands to fit into our budget limits. The results were pleasantly surprising, and recent price cuts and rebates across the board really helped. Of course, your own configuration may vary wildly from ours depending your own needs, priorities, or brand allegiances, but we think this is an awesome configuration for something building a new gaming PC.
Read on for our parts and price list, and contribute your thoughts and personal configs!
According to DigiTimes, Intel is looking to release two new processor models, which would most likely drop the prices on their current releases by up to 20 percent.
The two new rumored chips are slated to release on April 19th, and both will clock in at 2.66GHz. The first chip, the Q8400 (95W) will cost $183, while its sibling, the Q8400S (65W), will run $245. The report continued to state that in late May further Celeron and Pentium Dual-Core processors would see their way to the market.
For a full list of all the rumored price cuts and releases, be sure to check out a full report here.
Intel has made quite the splash in both the nettop and netbook markets with its low-power Atom processors, but it will be another month before the chip maker dives into the mobile internet device (MID) end of the electronics pool, says DigiTimes.
Citing un-named "sources at MID makers," the news and rumor site reports Intel has postponed the launch of its Atom Z550 and Z515 Atom CPUs to mid-April, both of which are intended for MIDs. When it launches, the Atom Z550 will run at 2.0GHz, making it the fastest clockspeed Atom to date. It will offer the same 2.4W rated TDP, 512KB of L2 cache, and 533MHz frontside bus. The Z515 will run a tick slower at 1.2GHz. Both chips sport an average power consumption of just .22W.
The Z550 will boast support for Intel's US15W chipset, while the Atom Z515 will support both the US15W and low-power UL11L chipsets. In addition, the Z515 will also feature Intel's new Burst Performance Technology (BPT), which will adjust the core clockspeed based on performance requirements.
News site DailyTech has gotten its paws on AMD's upcoming ATI Radeon HD 4890 videocard from an undisclosed source based in Taiwan, and has thus been able to confirm rumored details of the new card's spec sheet.
Built around the RV790 core, the Radeon HD 4890, as received by DailyTech, comes with a core clock of 850MHz . The site also reports 1GB of GDDR5 memory running at 3,900MHz resulting in 124.8 GB/s of bandwidth. Final memory specs could change, however, as the card DailyTech received came with Qimonda chips, which declared insolvency (went bankrupt) back in January 2009.
No word yet on a projected price point or release date, but not to be outdone, Nvidia plans to go head-to-head with ATI's 4890 with its GeForce GTX 275. According to reports, the upcoming GTX 275 is being built around the G200b GPU core with 240 shader processors chugging along at 1,404MHz. Other specs include 80 texture units, 30 render back ends, and a 448-bit memory interface. GPU and memory clockspeeds are expected to debut at 633MHz and 2,322MHz, respectively.
Look for the GTX 275 to launch on April 9, 2009 for somewhere between $230 and $280.
