Timing rules

LAN_deRf_HA — Wed, 19 Jun 2013 21:36:25 GMT

Working on tightening my timings, mainly secondary at this point, and I keep seeing people mentioning rules that many don't seem to follow. Like tRAS is supposed to stay above CL + tRCD + 2, but I've plenty of people drop tRAS to the floor without issue. I've seen a similar formula for tFAW.

And for stuff like tREF and tRFC what increments am I supposed to move those in? They're both such random numbers it makes me feel like they're supposed to follow a formula.

Corsair 900D Water Cooling Mod

Knight091 — Wed, 19 Jun 2013 21:31:17 GMT

UPDATED 04/19/13

Here is my water cooling loop idea. The dotted parts are behind the bays and will not be seen as well as the pumps other than the front of the clear pump so you can see the cooling etc. All you will see from the pumps will be the tubes coming out and the fittings to hold up the rez. I will make a fill port on the back side of the case hidden and have a main drain valve in the front between the two bottom rads. More to come.

Steam Game Sharing?

Those who opted into the Steam client beta may see some interesting language alluding to game sharing in the "steamui_english" file of the latest update. It's suggested that Steam users will be able to set a shared game library � when the original owner logs into the game, the game sharer gets a prompt to quit out.

If you want to see the file for yourself, you'll need to be running the beta version of Steam � go into Steam settings and opt in, then restart the client. Then, you'll need to head into your public folder and open the "steamui_english" file in a text editor like Notepad. Final step: crack open a cold soda, sit back and feel good about being a computer genius.

This sounds pretty awesome, if true. There are a lot of old games I don't play that I'd be willing to share with friends, and there are some that I'd want to play but not sure about actually buying as well.

Fops — Wed, 19 Jun 2013 18:49:00 GMT

Now you might be thinking this is a stupid question but as many of you know,gtx 680 is an overclocked 670 and 770 is just an overclocked 680 please tell me if im rong.my question is is it even worth getting a 770 when i could save my money and just overclock a 670?

Kingston HyperX Beast Black 2 x 8GB 2133 MHz C11 DDR3

cadaveca — Wed, 19 Jun 2013 18:46:45 GMT

Introduction

Over the past several months, I've covered no less than four different kits from Kingston. All were sent to me shortly after Kingston's HyperX brand celebrated its 10th Anniversary. Just as I finished work on the Predator review, Kingston asked whether I'd like to take a look at their new HyperX Black sticks, and I quickly said yes. What arrived on my doorstep, however, surprised me. Not only did I receive a Beast Black kit, but this one was also 16 GB in density with a default speed of 2133 MHz. What makes these sticks "Black" is the new black PCB that adorns many Kingston HyperX kits, but I, to be honest, expected a kit that closely resembled the 10th Anniversary Genesis sticks rather than the Beasts that were hidden behind the packaging's logo. What happened when I unleashed them on my 3770K testbench? They just might have torn things up.

Packaging

Kingston's now familiar packaging contains the HyperX Beast DIMMs. It is simple but effective.

Flipping open the lid was much nicer this time, with no green to be found anywhere--enthusiasts asked and Kingston delivered.

A Closer Look

What I found after taking a close look at the Kingston HyperX Beast Black DIMMs was all too familiar. Kingston's labels still appear to be mysterious notes from another world.

The "beast" reference in Kingston HyperX Beast Black DIMMs makes sense to me, with the heatspreader taking the shape of a beast-like head. Both sides of the sticks are identical except for the label on one side.

The heatsinks are shaped out of two pieces that interlock at the top and attach to the surface of the memory ICs with thermal tape. The top of the heatsink provides a tunnel air is trapped in, which will force fresh air down along the surface of the stick if suitable airflow is provided. The PCB's shiny top layer makes finding marking on the surface of the PCB harder than ever. There were some numbers on the PCB itself, but they were very hard to capture in pictures.

Initial Setup

The Kingston HyperX Beast Black DIMMS measure in at 46.44mm in height. This is roughly the same height as other Kingston HyperX Beast sticks I've seen, but such differences are probably due to variations in assembly.

Installed into my Maximus V Extreme motherboard, they make quite an impression, looking even more sleek than their green PCB brothers by offering a nearly 100% black esthetic. The bits of red on the heatsink are scarce enough to blend in well with any rig. Some heatsinks out there will cause clearance issues with these DIMMs, but cooler makers are now releasing more coolers specifically designed not to foul with memory sticks such as these, which will make such considerations less of a concern as time goes on. I am definitely eager to get my hands on a revised Noctua D14 I saw in Computex 2013 pictures.

I am using a fairly decent CPU overclock for all testing because greater CPU overlocks allow for greater memory performance increases to be utilized properly. I have picked many different benchmarks that show these differences, but not all workloads are going to see the same gains as these hand-picked benchmarks show. To show the increases, I started with two different memory kits, one from Samsung and one from Patriot. The Samsung kit is a 1600 MHz kit that features normal JEDEC timings for its speed; it is rated at 11-11-11-28-1T. The second kit is a much older high-performance kit that was meant to be used with P55 chipsets but missed out on full support with a Sandy Bridge CPU, since those CPUs didn't support the Patriot kit's 2000 MHz XMP speed with 9-10-9-27-3T timings natively. Ivy Bridge differs from Sandy Bridge in many ways, but one of the most important changes for gamers and overclockers is the addition of many more memory dividers, such as 2000 MHz, which makes this old kit useful again with Ivy Bridge as it wasn't matched to any of Sandy Bridge's default multipliers. I have spent several months testing these kits with various boards and both have worked great. I also test with a single ASUS MATRIX HD 7970 3 GB video card at an overclock of 1050 MHz for the core and 1500 MHz for the memory. This helps eliminate any sort of GPU bottleneck that might be introduced while, at the same time, showing to be sensitive to memory performance changes. Whether this is due to extra CPU or memory load is not known, or relevant. Let's take a look at what performance increases the Kingston kit offers:

Initial boot-up with XMP enabled was pretty easy, although I had to set secondary timings manually, as I have had to with many kits already. It's worth noting that the tertiary timings here are really tight due to the 1066 MHz JEDEC profile. For those that were wondering what dictates which tertiary timings are used on Z77 Express-based motherboards, it does seem to depend largely on the JEDEC profile. Some boards will scale these settings automatically as you increase frequency but my ASUS Maximus V Extreme does not. This is more an artifact of the test platform than it is of the sticks themselves. Two XMP profiles are available on these sticks: one for 2133 MHz and one for 1600 MHz. Like the Kingston HyperX Beast kit I covered a couple of weeks ago, the lower 1600 MHz profile does come with a lower voltage, which is great for heat reduction and slightly lowered performance, or CPUs with memory controllers not capable of running the 2133 MHz profile. I'm only going to focus on the 2133 MHz profile for today's testing because a quick set of benchmarks proved the 2133 MHz profile to be faster than the 1600 MHz profile. Tertiary timings, shown above in the MemTweakIt screenshot, are fairly tight, and I am keen to see their impact on performance.

I have to mention that these sticks offer 9-9-9-24 timings while running the 1600 MHz profile. It's not often we see 8 GB sticks offer such decent timings at 1600 MHz, with many kits sporting 11-11-11-27 or 10-10-10-27 timings. The wide level of compatibility at 1600 MHz and up to 2133 MHz was a real treat for me, giving me a clear idea of how these sticks would scale in my clock-scaling tests. I am very glad to see these sticks set up like this rather than having a profile that's only one bin lower than the rated speeds the sticks are sold for.

There is not much else for me to say at this point. I booted into my pre-installed OS and managed to complete all testing without much fanfare--as expected. The next couple pages have both system-oriented and 3D-oriented benchmark results for the kits. As is now the norm for me, I'll let the numbers do the talking.

Overclocking

Timing and Frequency Scaling

I also test modules for voltage requirements at different CAS settings and speeds to show how well a manufacturer has binned their modules and how well they've optimized them for the best possible performance. Would tighter timings and a lower speed make this module perform better? Can we increase or decrease voltage to get more performance? When overclocking, there are many different considerations that must be taken and this test helps with a few of those choices. For this test, I start with the default timings and a voltage of 1.50 V before figuring out the maximum speed I can achieve. I then go through the procedure with each working CAS Latency setting and each voltage interval. Different sticks are rated for different voltages, so the range I use depends on the stock voltage and how high each voltage takes me. With this set, I used a range of 1.5 V to 1.75 V.

Kingston, like some other companies, programs their SPD profiles with a lot of information, which makes testing for scaling a bit redundant. You can view this information easily by running AIDA64. I found the profiles listed above at the top of the listing, and these usually reflect "JEDEC" timings for any kit that is installed. These timings and speeds should run on any platform.

Then there is the 2133 MHz XMP profile labeled as the "Enthusiast" profile in AIDA64. Not only does it contain settings for 2133 MHz but it also has settings for lower dividers, which will have timings adjust automatically as you change the divider on some motherboards.

The third set of timings, the "Extreme" profile, starts with 1600 MHz as the main profile and has a few more below that.

Both XMP profiles also have configurations for higher CAS settings, to enable those options should your board support it. As you can see above, quite a few possible timings are already set for you to explore, and each stick should be able to run these timings at the above posted speeds without much issue. What you can get above and beyond that is going to change from set to set.

I tried to keep timings as close to the 2133 MHz XMP listings as possible with my set since those offered the best performance. I loosened the timings as required once I went up and ultimately landed in the same spot as on my test for maximum frequency. I managed to get a wee bit over 2400 MHz out of these sticks, which is not bad at all. With just barely being able to run 2400 MHz, there's not a lot of overhead with these Kingston Hyper Beast Black 8 GB sticks, but a lot of flexibility with tight tertiary timings results in pretty decent performance no matter how you want to run your system.

Maximum Overclock

When testing for maximum overclocks, I was able to reach 2400 MHz with a boosted voltage and loosened timings; I did not manage to get more by adjusting the baseclock. I retained the CAS Latency timing used for "stock" without any problems, but pushing much further proved to be nigh on impossible. Loosening other primary timings as I stepped things up helped reach that 2400 MHz, but I was still pushing 1.75 V through these sticks, which is a bit higher than I like for 24/7 use.

You'll find a bunch of benchmarks that illustrate the overclocked performance boost on the following pages. They are, again, broken into System Performance and 3D Performance sections. These sections include the XMP results of the HyperX Beast Black Anniversary 2133 MHz kit at the maximum overclock posted above, the previously tested kits with their overclocked numbers, and a reference JEDEC 1600 MHz set of numbers. As always, I'll let the numbers do the talking.

Value & Conclusion

	The 16GB (2 x 8GB) Kingston HyperX Beast Black 2133 MHz C11 kit is available for $155.99.
	Excellent stock and overclocked performance Large heatsink capable of running in extreme environments Dual XMP profiles at both 2133 MHz and 1600 MHz Wide compatibility with all current systems Simple, nearly mono-chromatic esthetics that suit a wide range of other enthusiast parts
	Run a bit hot and could use a fan when overclocked Large size can interfere with some aftermarket cooling options Not very much overclocking headroom in terms of raw frequency Random availability, with some retailers still selling sticks with green PCBs
9.5	We see new memory releases time and time again, and when they come with green PCBs, someone will mention that the color green sucks. Since we did away with green PCBs on most VGAs and motherboards long ago, I really have to agree. A green PCB is bad. Very bad. So, Kingston listened to those comments and changed the color. Enthusiasts the world over can rejoice! Kingston told me, asked if I wanted a sample, and sent me one. I expected little and received better than expected. When it comes time for me to run benchmarks for a review, I really don't pay much attention to the results, and since I run benchmarks often, they are usually just a blur of numbers I wait for so I can quickly press "PRT SC" on my keyboard to save the screenshot of the result to a file. I followed that same routine with the Kingston HyperX Beast Black kit I have here. Not paying much attention to the numbers themselves, I thought about the relatively low overclock these stick achieved and how those might influence overall performance. When it came time for me to create my graphs, I placed the Kingston HyperX Beast Black DIMM results into their proper places in my result files. CPU performance was as expected, but I couldn't believe what I saw when it came time to look at the 3D numbers. I'm not exactly sure what happened here, but I did go back, rebuild the test system I had torn down to replace with Haswell, and ran all the tests again. Somehow, these sticks are really good in 3D. It doesn't seem right, but that is what the results show. With a near 200-point boost noticed in 3DMark's FireStrike test, it's definitely not just a normal variance between tests. The last Kingston kit I tested, the Predator sticks, seemed to have some strange 3D abilities as well, so I can't help but think that there's perhaps a weird timing mix here that pays off in spades for Kingston, or I simply screwed up somehow (yes, I verified VGA clocks). These Kingston HyperX Beast Black sticks come at a fairly decent price for a 16 GB kit with two sticks, have a bit of headroom, and work on pretty much any system, and their blacked-out esthetics are sure to blend in well with nearly any build. These Beasts sure have been a bit wild for me, and they should be for you as well.

PopCap Turns Plants Vs. Zombies Into a Shooter

micropage7 — Wed, 19 Jun 2013 15:10:31 GMT

Opening Electronic Arts� press conference at the Electronic Entertainment Expo in Los Angeles this morning, EA Chief Operating Officer Peter Moore teased the first game of the conference: a new entry in �a beloved franchise that has captivated millions of fans worldwide.�

The video following, however, proved not to be the military shooter that it initially appeared to be, but rather Plants vs. Zombies: Garden Warfare.

Developed by PopCap Games using the Frostbite 3 engine that powers Battlefield, Plants vs. Zombies: Garden Warfare is a third-person action title set in the Plants vs. Zombies universe that combines shooter and tower-defense gameplay mechanics. Players may take control of familiar zombie-slaying plants such as the Peashooter, Cactus, Sunflower, and Chomper. Gameplay footage showed multiple players working together in a 3-D environment to defend the garden from oncoming waves of the zombie horde.

Garden Warfare is set to debut on the Xbox One, but will be coming to Xbox 360 sometime after that.

LG Intros First All-in-One Desktop with 21:9 Display

btarunr — Wed, 19 Jun 2013 14:05:05 GMT

LG used the ultra-widescreen IPS LED panels from its EA93 29-inch monitor to create the first all-in-one desktops to feature the dizzying 21:9 display aspect-ratio. The new V960 desktop from LG combines the 2560 x 1080-pixel display, with an NVIDIA GeForce GT 640M GPU, that's capable of handling most media and everyday tasks, at its resolution. Other hardware specs are known to include Intel Core i5 processor.

The V960 also includes a standalone TV tuner, which lets you use it as a TV, while keeping the PC component powered down. You also get the option to PIP (picture-in-picture) both facets, watching TV, while working on the PC. In addition to all that, the V960 can work as a standalone monitor, taking input from HDMI and MHL. LG also unveiled a variant of the EA93 that lacks the PC component, but features the TV tuner, and an additional DisplayPort input. The V960 is priced in the range of US $1,300 and $2,020, depending on the hardware configuration; while the tuner-equipped monitor is priced around $600.
