They finally did it! A new mini-ITX LGA 2011-3 has been announced by ASRock, the EPC612D4I, and this server-grade product will offer full quad-channel memory support with a switch to SoDIMM RAM.
Image credit: Tom’s IT Pro
While ASRock had previously released a mini-ITX X99 motherboard (the X99E-ITX/ac) there were concessions made based on the limitations of the form-factor, and the motherboard was limited to dual-channel memory with only two DDR4 DIMM slots. So for a full quad-channel experience it became obvious that a switch to SoDIMM’s would be required. So are there any DDR4 SoDIMMs available? They certainly aren’t cheap, but a quick search for the model number of this new board finds a page from Crucial for compatible DDR4 modules – at a cost of $555.99 for a massive 32GB (4x8GB) of 1.2V DDR4-2133 ECC memory.
Specs for the EPC612D4I from ASRock:
- LGA 2011 R3 Intel Xeon processor E5-1600/2600 v3 series
- 4x SO-DIMM slots, supports quad-channel DDR4 2133/1866 ECC
- 4x SATA 6Gb/s by C612
- 1x PCIe 3.0 x16
- Integrated IPMI 2.0 with KVM and Dedicated LAN (RTL8211E)
- Intel Dual GLAN (Intel i210 + Intel i217)
The new board was first reported by Tom's IT Pro and their article lists the retail price for the ASRock EPC612D4I at $265, which isn’t bad for a product like this. While definitely targeting the server market this could potentially be implemented for a very compact workstation setup (and allow creation of a PC to rival the diminutive Mac Pro, perhaps).

We haven’t had much more than rumor and speculation about upcoming AMD graphics for a while now, but there is more than enough fresh fuel for the GPU fire today to ignore completely. It seems that AMD and PC Gamer magazine have teamed up to announce a special (what else) PC gaming event at this year’s E3 show on June 16, and this would be the perfect place for some new hardware announcements.
Not enough for you? Well, while the AMD Fiji GPU rumors are nothing new to followers of industry news, it has now been indirectly announced that the upcoming Fiji GPU from AMD will in fact feature 2.5D high-bandwidth memory (HBM). As reported by tech news/rumor site wccftech the announcement came via the official schedule for the upcoming Hot Chips symposium, which is slated for August 23-25 in Cupertino, California.
This screenshot was taken this morning from the official online event schedule
(Note: This part of the day 2 schedule has now been changed to read “AMD’s Next Generation GPU and Memory Architecture”, with all mention of Fiji and HBM removed.)
Whether this gives us insight into the actual release date of the long-awaited Fiji GPU from AMD is unclear, but new AMD GPU products certainly seem to be imminent as we move into the summer months. Speculation is fun (for a while), but hopefully the PC gaming event at E3 in June will provide at least some official news from AMD on the new GPU products we've been waiting for.

Tagged: windows 10, microsoft, build 2015, build 10074, BUILD
When Microsoft forked their build numbers into 100xx and 101xx lines, we predicted that they were preparing a version to release at BUILD 2015. We also predicted that it would be heavily tested and pushed to both Slow and Fast simultaneously, which would give a good entry point for developers and probably even enterprise evaluators. I was surprised when Microsoft released 10061 last week, and then updated it just two days ago (why???) with four patches, but we ended up being correct in the end.
Microsoft has just released Windows 10 build 10074 to both Fast and Slow users. Its comes with a very small list of known issues, and they are much less severe than they were in previous releases. The first issue tells developers that Developer Mode needs to be enabled in Group Policy, rather than the place in Settings that it will eventually be. The next two issues are more severe: some games cannot be played in full screen and the People app is still broken. I am not sure how wide-spread “some games” is, but they plan to patch it via Windows Update “as soon as possible”.
One major fix is that now, when certain applications that play audio are minimized, they will continue to play audio. This bug made many media players, such as a few SoundCloud apps in the Windows Store as well as Microsoft's own Music app, pretty much useless. Until 10074, you would basically need to launch them, then cover them up with other windows if you wanted more screen real-estate.
If you were a fan of Aero from Windows 7, then you will like the blurred transparency effect of Start and the taskbar. Personally, while I think it looks nice, I was never really attached to that aspect of the Windows UI. Honestly, it used to drive me nuts when it kicked me out of games to complain about how it cannot properly manage 2GB of video memory, despite running perfectly fine if I select ignore. Hopefully that will not come back with it. But, if it is here without causing any problems, it does look pretty. Also, the Start Menu can now be manually resized to better arrange your apps. It also looks like the semi-horizontal layout is a great compromise between the Start Menu and the Start Screen for desktops.
So, as we expected, this build is what happens when Microsoft picks a target and mostly cleans up all of their relevant branches into a solid release. It is still a bit buggy here and there, but it feels better than 10049, which was itself better than 10041. That said, I also upgraded my NVIDIA drivers from 349.90 to 352.63; that could have something to do with it (although I am using the same Intel drivers).
There has not been too many announcements regarding features that are not present in 10074 though. It makes you wonder, at least a bit, how much will be added to the 101xx path until the OS finally launches.

Tagged: snapdragon 810, qualcomm, LG, Samsung
There have been many stories about Qualcomm's difficulties lately, from the court case with NVIDIA to Samsung and LG not using their Snapdragon 810 for their new smartphones. Qualcomm has struck back at the speculations about problems with this chip that rose from these decisions, pointing out that Microsoft, Xiaomi, Motorola and Sony will all be releasing devices with the Snapdragon 810 in the near future. LG put in their two cents as well, pointing out their decision to use the 808 chip was made over a year ago and they are still planning on utilizing the next generation Snapdragon 820 in the future, not to mention that they use the 810 in their G Flex 2. Samsung has also shown their belief in Qualcomm's products considering they will be fabbing the 820. You can see a short video of an interview with Qualcomm about this topic over at The Register.
"QUALCOMM HAS DEBUNKED chatter that LG ditched its octa-core Snapdragon 810 chip for the G4 owing to overheating problems."

The new Win 10 NVIDIA GeForce driver is here, in two different flavours depending on your form factor. If you spend the money for a gaming laptop with a GeForce 600M through 900M then this is the driver for you. On the other hand if you have a traditional desktop and a GPU or two then head to this page.
If you have a Sony laptop you should double check your GPU is covered and unfortunately at this point Hybrid Power technology is not supported. NVIDIA did not provide much additional information on the desktop side; it is a beta and so is the OS so make sure to record the full information about your bugs and crashes when reporting them, not just a frowny face followed by expletives.

Sure, pretending to be a gangster can be fun and the many gameplay videos of GTAV certainly make it look entertaining but it pales in comparison to the over the top chaotic gameplay of the Just Cause series. Watch the trailer below which covers a mix of gameplay, scripted events and cutscenes invoke. Now decide whether destroying a town with your grapple attached to a bus while flying a helicopter seems like more entertainment than using a mod to drop whales across GTAV's landscape. The modding community will certainly develop more interesting things to do in GTAV, then again the JC2 modders helped have the multiplayer version of the chaos simulator. Up to you if you would rather demolish things as a gangster or as a 'liberator'.
Whatever you do remember, only you can stop pre-orders.
"Watching the “gameplay reveal” trailer for Just Cause 3 is like watching the ambitions of every guns, vehicles and explosions game made real. It’s the ludicrously overblown action blockbuster that Uncharted’s scripted events and cutscenes invoke."

It has been a relatively quiet year for new CPUs and GPUs as we await new releases apart from the occasional incredibly high priced new product. On the peripheral side it has been anything but quiet, with numerous gaming mice and keyboards of both mechanical and other types being released. Not only that but we are finally starting to see both AMD and NVIDIA's variable refresh rate monitors appear on the market as well as new 4k and other more traditional displays. The Tech Report has some recommendations for all of the above as well as other backup peripherals, audio devices and more in this article here.

Tagged: nzxt, Noctis 450, mid-tower, enclosure, case
NZXT proclaims that “bold is back” with their new enclosure design, a striking-looking case based (at least internally) on the popular H440.
The Noctis 450 takes the H440 and combines it with an angular external construction that looks similar to the company’s Phantom enclosure series. As the interior is identical to the H440 this new enclosure features the spacious interior and excellent cooling support from the previous model. As a nice addition the Noctis 450 adds a PWM fan controller (and includes 4 fans), further simplifying cooling for a build with this case.
NZXT has created a product video to showcase the new design:
In the appearance department the Noctis 450 really does look good (although style is always a personal thing), with dramatic black/red and the familiar NZXT white/black color schemes available to help accent the interesting angles, and there is an adjustable LED lighting system as well.
Plenty of storage room (unless you're Allyn) with 5 slide-out HDD trays
The MSRP is set at $139.99 and the Noctis 450 is currently available for pre-order on the NZXT site.

Tagged: cirrus7, SFF, nuc, broadwell-u, fanless
Next month, German manufacturer Cirrus7 will begin shipping its new Nimbini system. The Nimbini is an even smaller variant of the company’s small form factor Nimbus PC. This time, Cirrus7 has managed to pack a Intel NUC system into a fanless case with multiple layers of stacked laser cut aluminum panels that double as a heatsink for the internals. Even better, the Nimbini supports Intel’s Rock Canyon and Maple Canyon NUC boards, and supports Broadwell-U processors up to the 28W Core i7 models with Iris Graphics (e.g. the two core, four thread, Core i7-5557U with Iris Graphics 6100).
The Nimbini will come as a complete system (150 x 150 x 87mm) preloaded with Windows or Ubuntu Linux operating systems or as a barebones DIY kit – which at upwards of 90 pieces (per FanlessTech) is not for the faint-of-heart! This case can be customized to add different covers and to vary the thickness of the case by adding or removing layers. The standard configuration leaves room for a 2.5” drive in addition to the usual M.2 SSD used with NUCs. If you aren’t using that second storage drive, you can make the case thinner or expand it for maximum cooling. While also aesthetically pleasing, the best part about the aluminum construction is that it is a fanless design which is perfect for a HTPC (home theater PC) or audio engineering setup. Cirrus7 claims to support up to 28W processor TDPs without any fans.
Rear IO for the Intel Maple Canyon NUC installed in the layered Nimbini chassis.
Cirrus7 will being taking pre-orders in May. Among others, both the Rock Canyon (with its IR receiver and accompanying case window) and Maple Canyon internal hardware (NUC boards) with dual DisplayPort outputs will be on offer. Pricing has not yet been announced, but it looks promising if you are looking for a premium silent SFF PC.

Tagged: microsoft, windows 10, BUILD, build 2015
BUILD 2015 begins tomorrow, and I expect we'll learn the last features that Microsoft intends to add to Windows 10 at launch. The conference is targeted at software and web developers first and foremost. We might not see too much on the consumer side, but we should get under-the-hood information that will be relevant to consumers. For instances, some questions about Windows Store, WinRT, and DirectX 12 might be answered. We might even get a public DirectX 12 SDK (and more).
Note: WinRT (API) is not the same as Windows RT (OS).
As we noted earlier, development was forked into a 100xx-branch and a 101xx-branch of build numbers. We assume that, due to the proximity to the conference, the lower build number is getting polished for public presentation while the higher builds will surface later, with more experimental features.
Microsoft published an introduction video, based on the 10061 build, to introduce the new OS to new users. I guess they are expecting a new wave of testers after the conference, probably both developers and enterprise evaluators. It is brief but interesting, although it surprisingly did not mention anything about the “Continuum” interface to switch between mouse/keyboard and touch experiences.
As stated, BUILD 2015 starts tomorrow and we will probably have a bit of coverage for it.

Tagged: pc gaming
If you have ever watched the movie Groundhog Day, then the premise of this game should be familiar. Garbage Day borrows its premise and lets the player do whatever they want for a day, and time resets. The game is said to justify the theme with a nuclear power accident, because the average person doesn't understand how nuclear energy works so why not?
In the movie, this gave Bill Murray countless opportunities, literally, to understand the town and figure out what he was supposed to do to move on with his life. This is the core of many video games, such as the Hitman franchise, but it is perceived as repeated failures. The game will supposedly have an end state to allow the player to break the cycle based on their actions. Unlike a stealth-action game however, it looks like it encourages goofing off as a means to soften the repetition.

Weighing in at 25lb empty, the IN WIN 707 is a serious case for those with a lot of components to house. Measuring 243 x 538 x 582mm (9.5" x 21" x 22.9"), with eight drive bays which can hold 3.5" or 2.5" drives a well as three 5.25" drives this case is designed for the storage junkie. The cooling options are also impressive, you can fit two radiators inside this case or opt for up to ten fans in a mix of 120mm and 140mm by removing some of the storage bays, if cooling is of more importance to you than storage. [H]ard|OCP liked the overall design, seeing as how it is essentially an IN WIN GR One with a different exterior but the lack of value added components such as runner grommets to reduce vibrations, sub-par filters and cheap feeling fan mounting clips detracted from their experience. On the other hand it is also less expensive and worth consideration for some peoples needs.
"The IN WIN 707 Gaming Version Full Tower case comes with a long list of features that reads to make it one of the best enthusiast hardware chassis you can buy. Tool-less design, spots for multiple radiators, E-ATX motherboard support, excellent CPU heatsink clearance, and designed for 10 fans. Does it measure up?"

When you pick up a Kingston HyperX Savage SSD you have a choice of the barebones model at $122 for the 240GB model or you can pay an extra $25 for the upgrade kit which contains 2.5mm z-height adapter, a SATA 6Gb/s cable, a 2.5" to 3.5" adapter plate, Acronis True Image HD imaging software, a micro-screwdriver set, and a USB 3.0 enclosure with USB 3.0 cable. That upgrade kit is perfect for those looking for an easy way to move their entire OS to the new SSD with a minimum of fuss. Inside the drive is the Phison PS3110 controller with a 256MB DDR3-1600 cache and Toshiba's 19nm Toggle Mode NAND. Hardware Canucks put the drive to the test and it shows huge improvements from the first generation, enough to put it in competition with offerings from OCZ, Intel and Crucial. This demonstrates a faster evolution that competitors products but it does unfortunately come at a price that is a bit high compared to those competitors offerings.

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):
For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.
Note to Linux users:
There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.
Note to mSATA 840 EVO users:
It appears the update does not currently apply to these. I've asked Samsung about this.

Kubuntu came about when Ubuntu switched to the Unity desktop environment as a KDE based alternative, which as Linux.com points out caused much disgust due to bugs at launch and a less than attractive interface. The newest version now uses the Plasma 5 environment, the first release to do so, replacing version 4 which has been in use almost decade now. This distro still uses Dolphin as its file manager but now uses Simple Desktop Display Manager (SDDM) instead of KDM. It also incorporates systemd, with these two changes users of Arch Linux will feel right at home. Check out the review for a list of the programs it ships with as well as the ones that Linux.com added after the fact to make Kubuntu work best for their machines.
"The latest version of Kubuntu, 15.04, aka Vivid Vervet was released last week and it's available for free download. With this release it has become the first major distro to ship Plasma 5 as the default desktop environment."

Tagged: Zen, Steamroller, Kaveria, k12, Excavator, carrizo, bulldozer, amd
There are some pretty breathless analysis of a single leaked block diagram that is supposedly from AMD. This is one of the first indications of what the Zen architecture looks like from a CPU core standpoint. The block diagram is very simple, but looks in the same style as what we have seen from AMD. There are some labels, but this is almost a 50,000 foot view of the architecture rather than a slightly clearer 10,000 foot view.
There are a few things we know for sure about Zen. It is a clean sheet design that moves away from what AMD was pursuing with their Bulldozer family of cores. Zen gives up CMT for SMT support for handling more threads. The design has a cluster of four cores sharing 8 MB of L3 cache, with each core having access to 512 KB of L2 cache. There is a lot of optimism that AMD can kick the trend of falling more and more behind Intel every year with this particular design. Jim Keller is viewed very positively due to his work at AMD in the K7 through K8 days, as well as what he accomplished at Apple with their ARM based offerings.
One of the first sites to pick up this diagram wrote quite a bit about what they saw. There was a lot of talk about, “right off the bat just by looking at the block diagram we can tell that Zen will have substantially higher single threaded performance compared to Excavator and the Bulldozer family.” There was the assumption that because it had two 256-bit FMACs that it could fuse them to create a single 512 bit AVX product.
These assumptions are pretty silly. This is a very simple block diagram that answers few very important questions about the architecture. Yes, it shows 6 int pipelines, but we don’t know how many are address generation vs. execution units. We don’t know how wide decode is. We don’t know latency to L2 cache, much less how L3 is connected and shared out. So just because we see more integer pipelines per core does not automatically mean, “Da, more is better, strong like tractor!” We don’t know what improvements or simplifications we will see in the schedulers. There is no mention of the front-end other than Fetch and Decode. How about Branch Prediction? What is the latency for the memory controller when addressing external memory?
Essentially, this looks like a simplified way of expressing to analysts that AMD is attempting to retain their per core integer performance while boosting floating point/AVX at a similar level. Other than that, there is very little that can be gleaned from this simple block diagram.
Other leaks that are interesting concerning Zen are the formats that we will see these products integrated into. One leak detailed a HPC aimed APU that features 16 Zen cores with 32 MB of L3 cache attached to a very large GPU. Another leak detailed a server level chip that will support 32 cores and will be seen in 2P systems. Zen certainly appears to be very flexible, and in ways it reminds me of a much beefier Jaguar type CPU. My gut feeling is that AMD will get closer to Intel than it has been in years, and perhaps they can catch Intel by surprise with a few extra features. The reality of the situation is that AMD is far behind and only now are we seeing pure-play foundries start to get even close to Intel in terms of process technology. AMD is very much at a disadvantage here.
Still, the company needs to release new, competitive products that will refill the company coffers. The previous quarter’s loss has dug into cash reserves, but AMD is still stable in terms of cash on hand and long term debt. 2015 will see new GPUs, an APU refresh, and the release of the new Carrizo parts. 2016 looks to be the make or break year with Zen and K12.
Edit 2015-04-28: Thanks to SH STON we have a new slide that has been leaked from the same deck as this one. This has some interesting info in that AMD may be going away from exclusive cache designs. Exclusive was a good idea when cache was small and expensive, as data was not replicated through each level of cache (L1 was not replicated in L2 and L2 was not replicated in L3). Intel has been using inclusive cache since forever, where data is replicated and simpler to handle. Now it looks like AMD is moving towards inclusive. This is not necessarily a bad thing as the 512 KB of L2 can easily handle what looks to be 128 KB of L1 and the shared 8 MB of L3 cache can easily handle the 2 MB of L2 data. Here is the link to that slide.
The new slide in question.

At $450 for 16GB of DDR4-3200, G.Skill's Ripjaws 4 kit is very well priced for DDR4 of that speed, especially if you like the active cooling fans. This particular kit is has timings of 16-16-16-36 with a 2T command rate. It also requires an impressive 1.35V to hit full speed, well above the 1.2V specification but in line with many of the other DDR4 enthusiast kits. Indeed when Hardware Canucks started their overclocking tests they raised that to 1.4V and managed a variety of tighter timings with reduced clock speed; worth noting is that all of those overclocks were successful when using a 1T command rate.

Seriously, won't SOMEONE please take this hardware from us? We are trying desperately to give it away...
Last month PC Perspective and Hardware Canucks partnered together to offer up a March / St. Patrick's Day themed giveawawy via YouTube. The problem? Only one of 15 people I contacted about winning replied - the rest were silent or replied and did not live in the US or Canada (one of the requirements). So to fix this, we are restarting the contest for the 2nd and 3rd prize winners.
The rules are basically the same: Subscribe to both PC Perspective's and Hardware Canuck's YouTube channel, live in the US or Canada, enter by May 4th!
We'll draw the winners and notify everyone that we have done so once we have confirmation from the participants. Good luck!
