Xtreme Computing had a chance to play with Crucial's new Ballistix MOD Temperature-sensing DDR3-1600 @ 8-8-8-24. They have the usual and fairly effective Ballistix heatspreaders, with the orange branding sticker in evidence and they can inform you of their current temperature using the Crucial MOD Utility. In their overclocking tests they could not breach 1820mhz
@ 1.658v though with the temperature sensor some may be tempted to go past that voltage to see if they can be pushed further.
"Today I’ll be reviewing one of their latest DDR3 products – the Ballistix 240-Pin DDR3 PC3-12800 with integrated temperature sensors. Yes – you did read that right, these dimms have built in temperature sensors! This is certainly new to me, and as far as I know, not offered by any other manufacturer at a consumer level."

HWBot is a board that keeps track of the successes that people have had overclocking various components and the benchmarks generated by those overclocks. MADSHRIMPS delves into one particular component, the RAM and looks at the three variables that generate the most pertinent to overclocking RAM, the Frequency, tCL and tRCD. There is a bit of math you need to follow in order to see how they arrived at the ratings on the charts at the end of the article, but then again if you want to get the best overclock you probably already have pages of notes from your own experiments.
"Everyone knows that the HWBOT database is filled with benchmark results, overclocking data and so much more. One of the perks of having a database like this is not only to amuse (and annoy) overclockers globally, but mainly to analyze the results afterwards and have a better understanding of how the overclocking game really works. Processor and video card charts are scattered around the website, but memory overclocking charts is something we have not touched before." Here are some more Memory articles from around the web:

X-bit Labs wanted to see what the integrated memory controller on Clarkdale chips is capable of and so tested it with RAM at speeds of 1333MHz, 1600MHz and 2000MHz with two different timings at each speed. As it turns out, the difference in performance between the three speeds was rather small, while the price of RAM kits rises noticeably. When they tried overclocking the Core i5-655K the results became more interesting and rather damning for the 1600MHz kit. Their findings should be of interest
for anyone looking at buying, or who already owns a Clarkdale based processor.
"The memory controller of the dual-core Clarkdale processors is seriously inferior to the integrated memory controllers of other Intel processors in terms of pure performance. We decided to check if there is a way to fix this situation by using overclocker DDR3 SDRAM." Here are some more Memory articles from around the web:

The Mushkin Blackline 12GB kit consists of three 4GB 1600MHz DIMMs running at 9-9-9-24 which lets you up the total memory available to your system without resorting to six DIMMs. That extra density doesn't seem to have much of an effect on overclocking, Overclock3D took the DIMMs past 1900MHz after they loosened the timings a bit. Check out how it changed the performance in the full review.
"4GB density RAM sticks are starting to appear on the market, so it was time for OC3D to have a look at one. Mushkin obliged..." Here are some more Memory articles from around the web:

The Crucial Ballistix Thermal Sensor Memory Kit that Benchmark Reviews got its hands on is similar to other kits that Crucial has released but offers an interesting feature. It has a temperature sensor built in that is able to determine the current voltage, speed, clockings and temperature and display that information for you. While that is a very handy tool for overclockers who are trying to determine just how far their RAM subsystem can be pushed this particular kit was not the best one to choose to integrate a sensor on. Try as they might, Benchmark Reviews could not convince these DIMMs to give them a decent overclock.
"Ask any PC enthusiast and they'll tell you that system heat is a constant concern, said Crucial Ballistix senior product manager, Jeremy Mortenson. The new Crucial Ballistix kit comes with a pair of innovations in memory cooling. The first one is an improved heat spreader design compared to the old models. This isn't such a big innovation in the memory market but the second will be an interesting one for sure. Crucial added thermal sensors for temperature monitoring via software. Since we're PC enthusiasts at Benchmark Reviews, the BL2KIT25664FN160 kit from Crucial couldn't miss our benchmark's suite and tests. Join us in this article to watch out what this new Crucial Ballistix Kit has to offer." Here are some more Memory articles from around the web:

The Patriot Viper II Sector 5 PC3 20000 4GB kit will set you back almost $350 but if you are looking for RAM speced at 2500MHz you already know you are going to be paying a steep entry fee. The timings look a little odd at first glance, 9-11-9-27 is not a usual set of timings but then again that does hint that there is some room to manoeuvre when you are adjusting your final clock settings. For instance, in testing OCC hit 7-9-7-24 @ 1800MHz and compared it to the 9-11-9-27 @ 2490MHz and did notice a difference in benchmarks. The number of motherboards that can support this speed are limited, as are the processors so read through the list of hardware that has been tested to support it and a bclock of 209MHz.
"When it came time to overclock the modules, the system was tapped out at 2500MHz on air. Maybe some sub-zero cooling could help these modules scale a bit higher. These modules will, however, run at lower speeds with tighter timings. Cas 6 was run at up to 1940MHz, Cas 7 to 2058 and surprisingly Cas 8 to 2490MHz. The only problem is to get the modules to scale, you need to bump up the TRCD setting in the memory sub-timings." Here are some more Memory articles from around the web:

Kingston's HyperX 1600/1866
LoVo RAM kit takes memory profiles to a new level. The reason that the DIMMs are rated for two speeds comes from the fact that it has two different profiles, the low voltage 1600MHz @ 1.25V or 1866MHz @ 1.35V, both significantly lower than the 1.65V maximum for DDR3 and an Intel Core family chip. The low voltages used mean that you can easily fit these into any system as no heatsinks are needed to cool the RAM. If you are building a PC that needs to fit in a small space or want a low power system then these DIMMs are perhaps your best choice. More at Bjorn3D.
"If you are a system builder looking for the absolute lowest power consuming PC then RAM
may be something thats overlooked. Extremely low voltage RAM like the kit of HyperX we have
here today can really help bring down power usage. This can be a great building block for
an extremely low power PC. This also future proofs your components in a way since Intel has
stated that the next generation of CPU's will use even lower voltage DDR3 than what is
common today. However we will be using this RAM on an AMD based system which does not
require the RAM to run at 1.65 volts or lower. This may be the case in a lot of computers
since AMD makes some of the most power efficient CPU's currently available."

If you have a socket 1156 processor that is looking for some of the fastest dual channel RAM on the planet then check out the Kingston HyperX PC3-19200 (2400MHz @ 9-11-9-27) 4GB kit. The price is unknown to Tweaktown, but at 2.4GHz and with an active cooling solution you know it will not be cheap. You don't have to consider that speed a solid ceiling, Tweaktown hit 2490MHz easily, with a bit more tweaking and a BIOS update or two you could probably top that. Read the full review to see where the extra speed really helps out.
"The HyperX name is getting stronger and stronger as the months go on. We see the company hit us with more aggressive modules on a constant basis these days. The best thing, though, is that when we hit that clock speed, we've been able to get even more out of the kit. Today we're dealing with a PC3-19200 (2400MHz) kit. That's some serious juice and you have to wonder once we hit that number, are we going to be able to get much further? - There's ultimately only one way to find out. Before we go looking at the overclocking potential and its performance, we'll first have a closer look at the package and the modules themselves."

Sometimes, the norm just isn't enough. Take our video editing and rendering system for an example; we have already discussed our transition to an ultra-high-end storage system that included either a set of FOUR 600GB Velociraptor hard drives or a pair of 256GB SiliconEdge SSDs. Now, after not a whole lot of discussion, the move from a 4GB allotment was necessary. The goal: 16GB.
After looking around online I found some Corsair 4GB FB-DIMM DDR2-800 modules that fit the bill very nicely. Our Intel Skulltrail motherboard only has four DIMM slots which is pretty low for a dual-processor platform so our configuration options were limited. At this point it would seem this is about as far as the platform is going to be able to take us.
FB-DIMMs differ slightly from your normal memory in that they are Fully Buffered; FB-DIMMS integrate a memory buffer between the memory controller in the chipset and the actual memories as an additional interface. This adds to the reliability and density the modules can support and is most frequently seen in servers and workstations. It adds to cost and complexity, as well as boot times, so you hopefully won't see it on consumer products anytime soon.
All we care about is getting 16GB of memory in our system to improve performance and limit the amount of times our machine needs to access that killer storage system...

With 890GX motherboards we are seeing some support for 2000MHz but unfortunately not all can reach that height. For instance the ASUS M4A89GTD USB3 that OCC used as the base for testing the 2x2GB Mushkin Ridgeback 996902 PC3 16000 is limited to 1800MHz. In theory, by reducing the total speed of RAM, you should be able to tighten the timings from their default of 7-10-8-27, though as it turns out that was a little optimistic. The final timings for their testing were 8-8-8-24 so perhaps this kit is not the best choice for those looking to underclock and tighten timings on an AMD board.
"Even after reducing the memory bandwidth by 200MHz for the review, the Mushkin Ridgeback kit managed to perform at a very impressive level. This really showed the additional performance gains by not only higher bandwidth, but also tighter timings. At 1800MHz, this set was still able to use timings of 8-8-8-24 with a command rate of 1T, and did so within the 1.65V requirement." Here are some more Memory articles from around the web:

Dropping $750 on RAM might be beyond the budgets of some, but if you do video editing or run a server with lots of connections or virtual machines, 12GB sounds just about right. That is where Crucial's new 12GB DDR3 kit comes in, three 1333MHz 4GB DIMMs with timings of 9-9-9-25 @ 1T. You can tell right away these DIMMs are not for the overclocker, there is no fancy heatsink assembly and when you install them you will notice a complete lack of XMP support. On the other hand the lifetime warranty and support
and low voltages make this perfect for a production machine. The full review is ready for you at Benchmark Reviews.
"It's always better to have and not need, than to need and not have. This Golden Rule applies to computer system memory as much as the other aspects in life, and having more RAM than your PC needs can only help matters. Multimedia editors require large amounts of memory to keep their encoding tasks moving at top-speed, otherwise the PC's much slower storage drive is called into play. Crucial offers the power-user a guaranteed boost to system performance, with their triple-channel 12GB DDR3 memory kit. The Crucial CT3KIT51264BA1339 UDIMM kit consists of three 4GB DDR3 modules rated for 1333MHz CL9-9-9-25-1 each. In this article, Benchmark Reviews tests the high-density RAM kit against memory big and small, fast and slow." Here are some more Memory articles from around the web:

FREMONT, California, May 6, 2010 — Corsair, a worldwide supplier of high-performance PC components, today announced the launch of the Dominator GTX4, a new ultra-high-speed module with operation guaranteed up to 2533 MHz. These modules are available immediately, in limited quantity, from the Corsair Online Store. Producing modules that perform at these extraordinary speeds requires an extremely meticulous, manual screening process, and each module represents the fastest thirty-two RAMs out of literally thousands of candidates. Each RAM chip is individually screened and graded for performance. The top few percent are set aside for assembly onto GTX4 modules, the balance are returned to normal manufacturing. Modules are then carefully assembled using these premium ICs, and only the fastest make the GTX grade. For an inside look on how this screening is done, click here. “The GTX4 modules are truly Corsair’s greatest expression of the memory overclocker’s art,” stated Michal Nowicki, a.k.a. Bachus, master overclocker at Corsair. “These modules are so fast that most CPUs will require sub-ambient cooling to run them at their maximum speed. Each GTX4 module represents hours of my work in the lab, and is authenticated by me personally.” Each GTX4 module is hand-tested in the lab at 2533MHz with latency settings of 9-11-10-30 at 1.65V. The test platform consists of hand-selected Core™ i7 “Lynnfield” CPUs on Gigabyte P55 motherboards. The GTX4 is currently available on Corsair’s web store, at shop.corsair.com. Due to the intensive screening involved, availability of the GTX4 module is very limited. GTX4 modules are supplied with a limited lifetime warranty and are backed up by Corsair’s legendary customer service and technical support.

Kingston's HyperX PC3 1866MHz LoVo DIMMs seem a little strange at first glance and not just because of the green heatspreaders. It seems counterintuitive that a HyperX module, billed as Kingston's fastest product line should also be environmentally conscious. It does make sense when you realize that the DIMMs have more that one JEDEC spec. The first XMP profile runs the DIMMs at 1.25V, nicely below the maximum voltage to be applied to a Core i7 or i5 processor and will run at 1600MHz 9-9-9-24 @ 1T. The second profile bumps the voltage to 1.35V and the speeds to 1866MHz 9-9-9-27 @ 1T. Tweaktown manually pumped the voltage to 1.55V and hit 2035MHz while still keeping the 9-9-9-27 @ 1T timings. Makes more sense to have a HyperX module billed as green now, right?
"We have to wonder, though; does Low Voltage and HyperX deserve to be in the same category? It seems a little conflicting. HyperX is all about power and Low Voltage is all about taking care of the environment and hugging trees. Let's hope that this isn't just some normal kit of memory with a new colored heatsink and fancy title. Hopefully we'll discover that the kit deserves to sit in the HyperX series and LoVo is something that we should be interested in." Here are some more Memory articles from around the web:

Before you dismiss Kingmax as a non-player in the RAM industry, you have to realize that their downfall happened due to a slow adoption of DDR, in the days of SDRAM they were, well, King. They have returned, the Kingmax Hercules PC3-17600 represents the higher end of DDR3. Clocked out of the package at 2200MHz @ 10-10-10-30 2T the frequency is unarguably high even if the timings look relaxed. Of course, to most enthusiasts this screams for an overclock or at least a tightening of the timings and Tweaktown could not resist and they hit 2346MHz
without adjusting timings or voltage.
"Every time I think of Kingmax my mind instantly goes back to the days of wishing so much that I could buy PC-150 TinyBGA modules from them, but only being able to afford PC-133 Apacer modules. There was a time when Kingmax was the memory to own; when we moved to DDR2, though, they did get left a bit in the dust to new performance company Corsair with its XMS lines of overclocked memory. Over the years we've seen Kingmax pull out a few stand-out performance modules, but recently they've been fairly quiet. With some new kits out and a new Hercules series they might just have what they need to get back into the lime light again." Here are some more Memory articles from around the web:

The Mushkin Ridgeback 998827 PC3 12800 kit is 3x2GB DDR3 DIMMs with a rather spiny look to them thanks to the integral heat spreaders. Natively they run at 8-8-8-24 but there is a bit of overhead left on these DIMMs, enough to take them over 2000MHz. OCC hit 2049MHz on their test system though the timings were reduced to 8-10-9-29 and they jumped the voltage to 1.68 from the recommended 1.65V. The kit is a little expensive but with the overclock that they can manage it might be worth your hard earned dollars. "When it came to the Ridgeback kit the limit was an amazing 28% frequency increase. This allowed for an additional 449MHz, for a total speed of 2049MHz. Not too many set's out there can reach beyond the 2000MHz mark, so this is very impressive showing, but equally impressive is that they scaled this high with the CAS latency remaining at 8. With this being the case end timings were 8 -10-9-29, a command rate of 2T, with the voltage needing to be set a 1.68 to fully run stable." Here are some more Memory articles from around the web:

As the name implies, the OCZ DDR3 PC3-12800 AMD Black Edition Ready 4GB Dual Channel Memory Kit is optimized for Black Edition AMD CPUs. It integrates its self with AMD's OverDrive utility allowing you to pick various profiles with the click of a mouse; if your motherboard offers support which not all do. From the review Futurelooks posted, it seems that these DIMMs offer more in the way of convenience than they do speed. An overclock of 1776MHz at 8-8-8-20 timings is not
terrible, adding 116MHz is nothing to sneeze at, but somehow seems disappointing in a
DIMM specifically designed for an unlocked CPU.
"There are no shortage of RAM kits in the marketplace. From a broad selection of speed ratings, to assist in overclocking, to the total amount of RAM you want. There are even RAM kits certified to work perfectly with either an NVIDIA SLI or ATI CrossFire setup. Though multi-card video card configurations can make overclocking difficult, so can a mis-match between the RAM and chipset. So why not produce RAM kits that are certified to work with, and be able to be overclocked on, certain chipsets and CPUs OCZ seemed to have been wondering the same thing with this AMD Black Edition Ready 4GB DDR3 Kit."

The Patriot Viper II Sector 5 2000MHz 4GB DDR3 kit sports timings of 8-8-8-24 and a price of $55 per gigabyte. If that seems a little steep to you it is because that is exactly what it is, however that is the penalty you pay for RAM that runs at 2GHz. The extra bandwidth did show up across the boards in the testing Legit Reviews did; though perhaps not enough of a difference to justify the cost. It is a great choice if you are looking to get the most out of your PC and it comes with Patriot's lifetime warranty if anything goes wrong for you. "In the need for some more memory bandwidth? Overclocking like a madman but running out of overhead with your DDR? Patriot thinks they have the answer with their Viper II Sector 5 2000MHz kit.

G.Skill's new DDR-1600 ECO Kit 4 GB might not offer the fastest frequency on the market, what it does offer are low timings of 7-8-7-24 and a voltage of 1.35V to keep the heat down. That isn't even as far as it will go on those stock settings as techPowerUp! hit 1715 MHz without touching the voltage and bumping the voltage up to 1.5V let them hit a healthy speed of 1.8GHz. If you are running a P55 system and are looking for some nice low latency RAM that you can play with, this kit is worth your consideration. "G.Skill is offering a full range of P55 compatible memory kits, with the ECO being one of them. As the name implies, the memory aims to deliver the most performance while only requiring a mere 1.35V to run at 1600 MHz CL7-8-7." Here are some more Memory articles from around the web:
