  Hyperthreading Bug
Posted by: SteelCrysis - 47 minutes ago - Forum: General Hardware - No Replies


Quote:Now, a major Hyper-Threading flaw has been discovered that can destabilize Intel CPUs based on both Kaby Lake and Skylake — not something Intel needed on the heels of AMD’s new CPUs. The issue is reported to cause “unpredictable system behavior,” which could mean anything from corrupting data to outright system crashes. The issue was picked up by Hot Hardware, via Debian.org. While Debian is a Linux distro, the warning makes it clear that the problem can happen to any operating system and is not limited to Linux.
Intel has apparently issued microcode updates for Skylake and Kaby Lake processors to address this problem, but they’ll need to be integrated into motherboard UEFI to work effectively. We recommend checking for board updates to see if there’s an update available if you’re using a Skylake or Kaby Lake chip.

For the record, while ExtremeTech believes Intel that these errata exist, we are not aware of any software programs affected by them and have not observed any issues with our Skylake or Kaby Lake testbeds. Our Core i7-7700K and Core i7-6700K both performed flawlessly when tested in our benchmark suites over the past six months.

If you’re having a specific problem with a piece of software that cropped up once you moved to Kaby Lake or Skylake, we recommend shutting off Hyper-Threading and seeing if that resolves the problem. Hopefully motherboard manufacturers will have solutions ready to go sooner rather than later.

  Edit: Microsoft Suffers 1.2 GB Leak
Posted by: SteelCrysis - 06-24-2017, 05:47 AM - Forum: General Hardware - Replies (1)


Quote:In what may prove to be a massive cybersecurity hazard in the long run, a large amount of internal Microsoft data about Windows 10 has been leaked online.

The files, found on BetaArchive, contain 8TB of compressed data that comprise of 32TB of internal builds for Windows 10 and Windows Sever 2016 and even software blueprints. This is believed to contain the code for Shared Source Kit, which includes the source for Windows 10's hardware drivers alongside PnP code, USB and Wi-Fi stacks, storage drivers, and ARM-specific OneCore kernel code.

All of these are critical systems for the operating systems and with their code available in plain sight to malicious parties; the massive leak, which is believed to have been taken from Microsoft's own systems, could prove devastating for the security of the OS in the future.

Alongside the source code were several as-yet unreleased builds for Windows 10, which included troubleshooting, testing and debugging tools used by Microsoft internally. Then, there's the Windows 10 Mobile Adaptation Kit, which seems to be an unannounced toolset designed at enabling Windows 10 to run on mobile devices.

The data seems to still be accessible to individuals with access to the private servers at BetaArchive and has been termed by some as being even bigger than the Windows 2000 source code leak back in 2004.

  Windows Task Manager Getting GPU Tab
Posted by: SteelCrysis - 06-23-2017, 03:44 AM - Forum: Software & Programming - No Replies


Quote:Microsoft is working on an update to Windows 10, which among several other things, adds a GPU utilization tab to Task Manager. You will be able to monitor each individual GPU in your machine, and Task Manager will give you live utilization stats for the GPU's 3D load, Video hardware-acceleration (encode/decode) load, dedicated memory usage, shared memory usage, and basic driver information such as driver version and date. For now the update is part of Windows 10 Insider Preview Build 16226; and will make it to the main-release in the coming months.

  Vega Thread

Quote:An MSI company representative posting on Dutch tech-forums confirmed our worst fears, that the RX Vega will have a very high power draw. "Specs van Vega RX gezien. Tering wat power heeft die nodig. Wij zijn er aan bezig, dat is een start dus launch komt dichterbij," said the representative who goes by "The Source" on Dutch tech forums Tweakers.net. As a gentleman scholar in Google Translate, and citing VideoCardz which cited a native Dutch speaker; the MSI rep's statement translates as "I've seen the specs of Vega RX. It needs a damn lot of power. We're working on it, which is a start so launch is coming closer."

  Tesla V100 PCIe Version
Posted by: SteelCrysis - 06-21-2017, 08:59 PM - Forum: Video - No Replies


Quote:The company announced yesterday that the V100 product line will expand by one when the PCIe version of the the Tesla V100 compute card starts shipping by the end of the year. The card will join a suite of previously-announced products that use Nvidia's proprietary NVLink interconnect.

The PCIe Tesla V100 is just a bit tamer than its brethren, a byproduct of a TDP cut to 250 W from the 300 W figure of the other V100 products. The specifications are about 6.5% lower across the board, suggesting that only the clock rates changed.
The bandwidth to the rest of the system is chopped down quite a bit, plummeting from the second-generation NVLink's mind-boggling 300 GB/s to a more pedestrian 32 GB/s. The on-package memory is 16 GB of HBM2 on a similar setup to the NVLink version of V100, offering the same 900 GB/s of bandwidth over a 4096-bit interface.

The PCIe Tesla V100 is arriving roughly at the same time as AMD's Vega Frontier cards, and some comparisons are inevitable despite the difference in architecture. The memory speed, capacity, and the single- and double-precision FLOPS specs aren't terribly far off from one another, though rumors suggest that AMD's cards will require a big chunk of power. The second half of the year should be an interesting time for GPU computing.

Nvidia didn't offer pricing information for the PCIe version of Tesla V100, though you can bet it will be exquisitely expensive. The company says that the cards will be available before the end of the year from Nvidia resellers partners and manufacturers including Hewlett-Packard Enterprise. We are unsure if this means that cards will only be available as a part of new systems or if they'll be selling individually. In any case, stay tuned.

  Samsung Increasing 64-Layer V-NAND Production
Posted by: SteelCrysis - 06-19-2017, 04:22 AM - Forum: General Hardware - No Replies

I had been bouncing back and forth over whether to post this, but the detail about 90-layer NAND convinced me to post this.

Quote:It seems that lately every storage semiconductor company is engaged in an all-out war and crowing about chips made with an ever-increasing number of layers. Samsung's the latest to talk up its silicon cookies. The company says it's ramping production of its 64-layer V-NAND chips now, and it expects half of its V-NAND flash production to be of that type by the end of the year. 64-layer V-NAND previously began shipping to "key IT customers" in January.

Samsung says that its chips can hit speeds of 1 Gbps, making them the "fastest among currently-available NAND flash memory." The new offerings are more frugal, too, seeing as they only require an input voltage of 2.5 V, down from the 3.3 V required by Samsung's previous-generation 48-layer chips. The company also says that the new chips offer 30% better energy efficiency and that the new V-NAND cells have 20% higher reliability. Finally, the 64-layer flash has what the Samsung calls the "industry's shortest page program time" of 500 μs, a number that the company says is four times faster than typical 10-nm planar flash and about 1.5 times faster than its own 48-layer V-NAND.

Looking to the future, Samsung believes that the industry will start competing by offering better performance and reliability for flash chips instead of focusing solely in a race to the feature size bottom. The company also states that it has the "fundamental technology" to create 1 Tb flash chips with 90 layers of cell arrays in the future. We look forward to it.

  Atari's New Console
Posted by: SteelCrysis - 06-17-2017, 07:22 AM - Forum: Gaming - No Replies


Quote:As the week comes to a close, we are getting word that Atari CEO Fred Chesnais has confirmed that his company is working on a new console. It was only last week that the video above surfaced, showing off what would be a teaser trailer for the Ataribox. While it was unknown at the time whether this was a hoax, Chesnais did confirm that the new console would offer the iconic wood-grain siding which was found on its older consoles.

At this point, we don't know whether or not this will be some kind of retro console like the NES Classic or something completely new and unique. Atari did announce plans in 2014 to bring new hardware to market, maybe this upcoming device is the result of that effort. Naturally, we will just have to wait and see.

  ASRock's Unethical Rebate Rewards Program
Posted by: SteelCrysis - 06-17-2017, 03:19 AM - Forum: General Hardware - No Replies

Don't let TPU's conclusion sway you: this is unethical. Giving rewards in exchange for reviews results in positively skewed reviews. Amazon had to ban a somewhat similar practice last year for this reason.
