During their rounds at IDF earlier today, Fudzilla has acertained that Core i7 will in fact have an unlocked memory multiplier. It wasn't that long ago that a very sour rumour had emerged regarding Nehalem's ability (or therelackof) to run high speed (1600MHz+) DDR3 independantly of the CPU clockrate and voltage; this due to what was believed to be a limitation of the combined memory controller.
This report clears a few things up and puts those fears to rest, also making mention of Nehalem's ability to run different memory configurations (including mismatched modules) without any hiccups.
The granularity is 64MB, in other words, the smallest size on one interleave would be 192MB, although it's unlikely that someone would end up with such a configuration, as the smallest DDR3 modules are 512MB. Again, this is good news for people planning to upgrade, as it's possible to run with unevenly configured memory, but according to Intel you get the best performance if you keep the same amount of memory in the same channel, although this doesn't mean the same size modules in each channel.
For example, if you own a 2x2GB DDR3 kit today, you can compliment it with a 2x1GB kit and split it into 2GB per channel for the best overall performance. This means that triple-channel memory kits might not be as popular as first expected and it could possibly upset a few memory manufacturers that hoped to sell a lot of triple-channel DDR3 memory kits.
Check out the full report here.
While sadly ASUS forgot to invite us to its X58 launch event last week in Taipei, A-DATA were kind enough to send through plenty of data about the event for us to talk about right here.
ASUS were out in force showing off their ranges of Core i7 supported X58 Express motherboards to attending press but maybe more interesting was the fact that A-DATA displayed its DDR3-1600X triple channel memory working at 2000MHz DDR (and beyond) - oh and by the looks of things, there were plenty of showgirls on standby incase the crowd got bored.
This was all done with an ASUS P6T Deluxe motherboard and Core i7 processor. Using the Everest benchmark, a memory bandwidth read speed score of 20,515MB/s was achieved.
Clearly we can see that A-DATA are well and truly ready for the Intel Core i7 on November 17th and we look forward to checking out this memory and more - it is going to be interesting comparing single channel, dual channel and triple channel to see what different there really are.
You can find the full details of the press event over at the press release, which we uploaded here earlier.
Following the launch of A-DATAs new triple channel memory kits for the upcoming X58 platform, the company decided to get together with ASUS and stick the three modules into a P6T Deluxe motherboard, which we've heard and seen a lot of in recent times.
Not satisfied at the rated 1600MHz speed, A-DATA pushed the modules to speeds of over 2000MHz and then proceeded to demonstrate just how awesome the memory bandwidth is on Nehalem.
As you can see above, the result was a massive 20GB/sec read speed and just under 17MB/sec write; leaving any Core 2 setup well in the dust.
I'll now leave you to feast your eyes on ASUS' fully fledged Rampage II Extreme X58 board, ready and waiting for those with deep pockets.

Lexar Media has just launched its new line-up of Crucial Ballistix Tracer DDR3-1333 (PC3-10600) memory, sold individually as 1 and 2GB modules or 2 and 4GB dual-channel kits. Being the newest members to the Tracer series, these modules incorporate an eye-catching new black heat spreader design with Crucials proprietory activity-indicating LEDs. The black PCB of the modules themselves further compliment the new design.
You can see in the above shot, four additional blue LEDs are positioned on each side of the modules for added bling. The modules will run at their rated speed of 1333MHz with latencies of just 6-6-6-20 at 1.8v.
Pricing for the modules come in at $54.99 for the 1GB module, $99.99 for the 2GB whilst the 2 and 4GB dual-channel kits are $109.99 and $199.99 respectively.

Fremont, CA, and Glasgow, UK, 7 October, 2008 -- Lexar Media, a leading global provider of memory products for digital media, today announced immediate availability of Crucial Ballistix Tracer PC3-10600 (DDR3-1333MHz) high-performance, low-latency memory modules. These modules are the world's first high-performance DDR3 memory modules to incorporate activity-indicating Light-Emitting Diodes (LED).
With Nehalem being confined to DDR3 only, memory makers are beginning to leave DDR2 in the dust as they push to release bigger and better DDR3 kits. Patriot has just announced a kit with the best of both worlds in capacity and high performance.
The new Viper Series 4GB PC3-16000 kit is capable of operating at its rated 2000MHz speed with timings of 9-9-9-24 at 2.0v. If you're running an NVIDIA 790i SLI platform these modules also feature EPP2.0 to optimize their specification automatically.
You can read more about Patriot's new DDR3 PC3-16000/2000MHz 4GB kit within the official PR here folks.
Patriot Memory, a global provider of premium quality memory module and flash memory solutions, today unveiled their 4GB DDR3 2000MHz low latency Viper series memory kit. The newest addition to Patriot's Viper series, the 2000MHz kit boasts both high-density and high-frequency, enhancing overclocking capabilities for gamers and PC enthusiasts alike on today's latest DDR3 platforms.
"Patriot's DDR3 2000MHz memory kits are perfect for PC gamers and enthusiasts," said Les Henry, Technical Director of Patriot Memory. "Capable of handling the demands that high-bandwidth multimedia programs and PC games require, the 4GB PC3-16000 2000MHz memory has the perfect combination of density and speed to push systems beyond what is currently imaginable."
It has been confirmed that Bloomfield (Core i7) CPUs will initially support only DDR3 800 and 1066 MHz memory. DDR3 1333 MHz support will not will be part of Intel's initial equation, yet would be within reach via dabbling in the arts of overclocking.
Speeds in excess of DDR3 1600 are also possible, yet will of course not be supported by Intel.
The article concludes with claims that Intel may, shortly after launch, validate support for DDR3 1333 MHz and higher, yet further information is not available at this time.
Team Group has today announced its latest high-end overclocking series DDR3 memory.
The so-called "Overclocking Heroic Duo" DDR3 memory by Team comes in a 4GB dual-channel kit and runs at either 2000MHz or 1800MHz DDR. The modules feature an 8-layer PCB design and over-sized Xtreem heatsink to keep things nice and cool.
If you are running the memory at 2000MHz DDR, you'll need to set the memory voltage to 1.9 volts and run timings of 9-9-9-24 and 2T and at 1800MHz DDR, you'll also need to set the memory voltage to 1.9 volts and run timings of 8-8-8-24 and 2T.
Not too shabby at all for a 4GB kit - we'll try and get a kit in for review soon, but for now take a look at the press release, over here.
The folks over at Nordic Hardware have scooped up a bunch more interesting information in relation to the behaviour of Nehalem's memory system and how DDR3 will perform on it under overclocked conditions.
As has been mentioned previously, the Nehalem platform has been said to only carry official support for DDR3-800 and DDR3-1066, though some sources are indicating that DDR3-1333 memory support will also be included. Nordic explain that although there has been some confusion as to why Intel Core i7 would not support DDR3 memory clocked at higher frequencies, the first thing you need to be aware of is that it is not the frequency of the memory that is the culprit.
The problem is rather that the memory and the processor internals are fed synchronized voltages. Previous reports have stated that anything above 1.65V would fry a Nehalem processor and it would certainly be hard to get any of today's DDR3 memory modules to any kind of decent speeds at this voltage. But, these stories are exaggerated, but the fact remains that Nehalem processors are not going to like voltages above 1.7V.
So, it would appear the limitation comes from not being able to make use of higher voltages without potentially overheating/killing the processor. For this reason, the memory will not be able to be pushed as much as on a current-day Core 2 platform where the memory controller is seperate, thereby having its own voltage circuit.
Hopefully as DDR3 further matures, we will see modules hit the market with extreme speeds at low voltages to counter-act this problem.
In a report over at HEXUS, it is begin suggested that Corsair is set to release an 8GB DDR2 kit later this month with low latency.
Since DDR2 memory pricing is still good, Corsair clearly reckons that there is a market out there for users wanting 8GB. The report says that Corsair guarantees that the modules will operate together at 800MHz with a low latency of 4-4-4-12.
The kit is set to consist of four matched CM2X2048-6400C4DHX DDR2 modules and also feature Corsair's Dual-Path Heat Xchange (DHX) technology.
And here I was thinking 4GB was plenty enough...
There appears to be a new competitor ready to get a foothold in the, increasingly competitive, memory marketplace.
Gingle, is throwing its hat into the ring with a 4 GB DDR3 kit offering, claiming 1800 MHz speeds on an Intel P45 platform and, 2000 MHz speeds on an NVIDIA 790i solution.
The modules are endowed with, what the company believes are, lower latency timings of 8-8-8-24 and feature striking black heatspreaders, with gold accents and trim.
Circa 1.84V on an Intel P45 platform and 1.94V on an NVIDIA 790i platform are the power requirements stated, with Gingle hedging its bets on this one by comparing the attractiveness of its product, on a like-for-like basis.
With an 8 layer PCB forming the foundations, will Gingle gets its competitors quivering in their boots?
