Elpida and Buffalo Technologies have unearthed a memory standard never before heard, and thought by many, as the limits of current DDR3 technology, given the silicon fabrication process current DRAM chips are made with. The elusive PC3-19200 standard has been achieved. Elpida has tested stable, a prototype memory module that runs at 2400 MHz DDR (1200 MHz actual clock-rate). The modules use Elpida's 2.5 Gbps DRAM chips.

These speeds, however, come at the cost of latencies and voltages. The module was tested stable at 2400 MHz only at 11-11-11-34, and a voltage of 2.1 V, which is high, by DDR3 standards. However, the module locks a surprise when it comes to the same numbers: The module was tested stable at 2096 MHz, at amazingly low 1.5V, with much tighter timings of 9-10-9-24. The companies wish to put this to mass production soon

Recently the processor phenom X4 9950 Black edition with 2.6 GHz frequency existed only in one version with the marking form HD995FAJ4BGH. It is based on B3 stepping, TDP value for this model is 140 W. Naturally, this hot processor cause problem for users and also motherboards producers - the latter cannot assure compatibility with this processor using inexpensive products.

AMD promised to release the colder version Phenom X4 9950 Black edition, and to gradually remove from production the old version. This week in Japanese stores appeared the processor with marking HD995ZXAJ4BGH. From its predecessor it is differed in terms of the TDP Level : not more than 125 W.

This Concrete copy was released in 36Th.week of the present year : in the beginning of September.

Japanese salesmen assert that the TDP level of this processor does not exceed 120 W. Which is interesting, the hotter version phenom X4 9950 Black edition in Japanese stores costs almost up to $20 cheaper than the new one. Officially there is no difference in price between two processor versions .

Red and green LEDs mounted between the DIMM sticks’ black aluminum heat spreaders and above the top edge of the black PCB light up in sequence based on memory activity. Eight blue “ground effects” LEDs mounted closer to the bottom of the module, near the pins, cast their glow on the DIMM sockets.

But there’s no need to break out your old Morse code book; you won’t be able to divine much, if any, insight on what your PC is doing based the Tracer’s light show.

The modules operate on 1.8 volts of power and by default run at 1,333MHz with 6-6-6-20 timing. Since the word on the street is that Intel’s upcoming Core i7 architecture won’t tolerate DIMM voltages higher than 1.65V, we pinged our Lexar contact to ask about future compatibility. We got the following long non-answer:

“We’re working closely with Intel and other motherboard manufacturers,” said the Lexar spokesperson, “to ensure we have Crucial memory products that support the upcoming platforms and technology. We haven’t finalized our products to date, so we’re not able to share specific product details at this point in time. We’re confident we’ll have Crucial products that support these new, upcoming platforms.”

A 2GB kit (two 1GB DIMMS) sells for $109.99; a 4GB kit (two 2GB DIMMS) goes for $199.99. We enjoy bling as much as any performance-rig builder; but based on the comments above, we wouldn’t recommend anyone invest in new memory today if your intent is to migrate it to a new Core i7 motherboard down the road.

It looks like Intel’s upcoming Core i7 platform will have tight limits on the maximum DIMM voltages that can be safely used. According to information uncovered at the Inquirer, motherboard manufactures have been told by Intel that DDR3 memory when set to use voltages higher than 1.65V can burn out the CPU of upcoming Core i7 platforms.

Images of an unreleased Asus X58 motherboard in its apparent retail packaging show a sticker placed across the DIMM slots stating “According to Intel CPU SPEC, DIMMs with voltage setting over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage setting below 1.65V.” According to the Inquirer, Asus had said it is safely running memory kits at 1.7V in its labs, but beyond that voltage you are on your own.

When Tom’s Hardware contacted Intel on the matter, Intel told us that it could not comment since details regarding Core i7 platform overclocking have not yet been made public. Intel did say however that it feels that knowledgeable overclockers will be pleased; a statement that agrees with early reviews of the Core i7 platform.

What we do know about Intel’s upcoming Core i7 platform is that it does not use a Front-Side Bus, making CPU overclocking essentially independent of the RAM. According to Fudzilla however, CPU and memory voltages on the Core i7 platform are synchronous, creating a potential limit for extreme overclocking if the CPU can only handle 1.65V safely.

What this also means is that consumers wishing to use current generation performance DDR3 memory with a Core i7 system may be in for a disappointment. Much of the performance memory currently available use a voltage greater than 1.7V, such as Patriot’s Viper 4GB 2000 MHz DDR3 memory that operates at 2.0V. It is expected that memory manufactures will release DDR3 memory kits designed for the Core i7 platform with some manufactures already announcing such plans. For example, A-Data’s recently announced a tri-channel DDR3 memory kit that operates between 1.65V to 1.75V and offers a latency setting of 7-7-7-20 2T for DDR3-1333+.

Unlike Intel’s Core 2 platform, the Core i7 platform uses triple channel memory, meaning memory kits designed for the Core i7 platform will come with three memory sticks instead of two. This fact alone might help prevent consumers from accidentally buying memory kits incompatible with Core i7 systems. Intel is expected to release the Core i7 platform in November for the upper mainstream, performance and enthusiastic markets

Earlier this year, Mushkin acquired Exceleram to expand its technological expertise and manufacturing footprint. Exceleram had been in the business of high-performance gaming system memory modules for quite some time. Post acquisition, Mushkin lets Exceleram products, both current and future, retain the Exceleram brand name and product logos. News is, that the company launched two dual-channel DDR3 memory kits.

The EX3-21800X2-S2 is a 2x 1GB kit, that operates at 1800 MHz DDR, with timings of 8-8-8-24 and DIMM voltage of 1.85~1.90 V. The EX3-41600Q2-SM is a 2x 2GB kit. This is where the bank density eats into other parameters such as timings and frequency. It operates at 1600 MHz DDR, with looser timings of 9-9-9-27. On a positive note, the module voltage has been pushed down to 1.7 V, and it won't be too far-fetched to estimate, that the modules could operate at 1333 MHz at much lower voltages. While there's no word out on the pricing yet, Mushkin on its part states that the products would sell at "unbeatable prices".

As the computer enthusiast community gears up for Nehalem November, with reports suggesting a series of product launches for both Intel's Core i7 processors and compatible motherboards, Industry observer PC Online.cn have already published an in-depth review of the Core i7 940 2.93 GHz processor. The processor is based on the Bloomfield core, and essentially the Nehalem architecture that has been making news for over an year now. PC Online went right to the heart of the matter, evaluating the 192-bit wide (tri-channel) memory interface, and the advantage of HyperThreading on four physical cores. In the tests, the 2.93 GHz Bloomfield chip was pitted against a Core 2 Extreme QX9770 operating at both its reference speed of 3.20 GHz, and underclocked to 2.93 GHz, so a clock to clock comparison could be brought about.

The evaluation found that the performance increments tri-channel offers over dual-channel memory, in real world applications and games, are just about insignificant. Super Pi Mod 1.4 shows only a fractional lead for tri-channel over dual-channel, and the trend continued with Everest Memory Benchmark. On the brighter side, the integrated memory controller does offer improvements over the previous generation setup, with the northbridge handling memory. Even in games such as Call of Duty 4 and Crysis, tri-channel memory did not shine.

The E7400 is on sale in Japan now. The frequency of E7400 is 2.8GHz, higher than E7300, but it doesn’t support the Trusted Execution Technology. Except for this, the E7400 is as the same as the E7300.

The price is 16000Yen, about 160USD and it will be on sale in other places soon.

We were shocked to see Intel's 80-core CPU that was up and running at Gitex Dubai trade show. To make it more interesting, Intel was showing it off at the general public area outside of the tradeshow and we found out about it by chance.

First of all, this is not Larrabee; we’ve asked, and the engineer guarding this live demo with his life told us that this is a project that started even before Larrabee. This is a CPU of the future that features 80 small cores and this CPU can perform 1 Teraflop with these 80 cores with 78.35W and 3.13GHz clock speed.

This CPU is smart; if you don’t need that much computational power it will shut down most of its cores and downclock the CPU all the way to 780MHz, the peak Teraflops performance will drop to 0.01 and it will only need 6.45W to compute the 4tile, 4x4 matrix mult withcomm equation.

We also learned that this research CPU should be ready to market in five to seven years and that the current demo CPU was done in 65nm. This is the direction that Intel is taking; so after eight, sixteen, thirty-two and sixty-four there will be an eighty-core CPU and that should happen between the sixty-four and ninety-six core versions. Sounds crazy, doesn’t it? But this is the direction.

We can only hope that Intel can make the software guys find a use for eighty cores, as they are struggling to put four of them in good use. This is what it looks like and more to come soon.

The processors phenom II X4 940 Black edition (3.0 GHz) and Phenom II X4 920 (2.8 GHz) was put already on the market, and the proximity degree of real prices to the recommended values $275 and $235 depends on the specific region character or concrete salesman. We note that elder two existing 45 NM processors phenom II X4 has a free multiplier, and they are supplied in the box without regular cooler - the majority of potential buyers use more powerful cooling systems.
