Unlockable ability will boost flash controller speed for faster reads and writes
Overclocking your DRAM memory remains one of the most popular aftermarket tweaks of enthusiasts. The imperfect art of adjusting voltage and timings has long been able to offer snappier performance depending on your system's bottlenecks and the quality of memory sticks in the box.
While on the surface NAND flash storage resembles DRAM, it has thus far remained
unavailable for overclocking
ever since SSDs began to creep into the market in volume around 2003.
: Better Late Than Never
But that could soon change.
Intel Corp. (
) quietly posted about a Sept. 10 technical presentation "
AIOS001 - Overclocking Unlocked Intel® Core™ Processors for High Performance Gaming and Content Creation
" at the
2013 Intel Developer Forum
(IDF) in San Francisco, Calif. At the presentation, it's expected to unveil the tardy 22 nm
Core i7-4000 and X79 platform, and with it SSD overclocking. The presentation was
first noted by
, a Chinese language hardware site. A list of presentation topics comments:
Overclocking architecture of the Intel® Core™ i7-4xxx series processors on Intel® X79 Express Chipset based platforms
Overclocking architecture of the desktop and mobile 4
Generation Intel® Core processors
Live demonstrations and expert tips from an industry partner on how to push the limits of Intel® unlocked processors using software and hardware tools from the enthusiast ecosystem
One of the first public demonstrations of overclocking the Intel® Core™ i7 4xxx Extreme Edition processor
Demonstrating overclocking SSD technology
First public demonstration of AppTune beta based on Intel® Extreme Tuning Utility (Intel® XTU)
It's unclear whether the SSD overclock will be reserved for only the 22 nm
-E series chips, or will be open to
as well. Intel typically uses its "E" series to introduce Xeon multicore editions of its architecture, and higher clocked desktop consume Core i7/Core i7 Extreme branded chips.
platform is expected to be introduced at IDF, next month.
launch is a bit late -- Intel launched
in Nov. 2011, nearly eight months after the
's initial launch. By contrast, the 22 nm
launched in April 2012
, but has seen no "extreme" update in nearly a year and a half (17 months). At the head of the new consumer "Extreme" chips is rumored to be the Core i7 Extreme 4960X, a monster that packs 15 MB of L3 cache and is turbo-clocked to 4.0 GHz.
II. SSD Overclocking -- SATA on Steroids or Hype?
When it comes to the SSD overclocking, the upcoming platform is expected to allow you to apply more voltage to your SSD controller to bump your read, write, and IOPS speed. Performance will be capped at 4.8 Gbps (614 MB/s), though, due to the fundamental ceiling of the current SATA 3 standard implementation supported in Intel chipsets (The raw performance of SATA 3 is 6 Gbps).

That still would seemingly suggest that overclocking SSDs could offer some impressive gains.
Currently the fastest SSD in terms of read speeds is
from OCZ Technology Group Inc. (
), who boasts (under light load) a gaudy 547.3 MB/s (4.28 Gbps) read and 657.9 MB/s (5.14 Gbps) write; but there's a catch -- this pricey (~$2,800 USD) OCZ drive
uses PCI Express
. High end SATA 3 drives
and Samsung Electronics
Comp., Ltd. (
) score a more sluggish 290-320 MB/s (2.27-2.50 Gbps) read speed and 370-400 MB/s (2.89-3.13 Gbps) write speed, according to
the latest numbers
's benchmarking (again, light load).
While it's clear that the current real world performance numbers are far from the theoretical 4.8 Gbps spec limit, skepticism is warranted. It remains unclear whether simply how far current drives can be pushed with higher voltage and faster clock speeds to the controller. Regardless of the real gains, this does mean we will see upcoming enthusiast SSD packaging with a focus on controller cooling with flashy finned heat spreaders,
like we've seen in the enthusiast RAM market
(case constraints may limit creativity for now, though).
Intel is working on a new chipset, which is rumored to be dubbed the 9 Series (
Z97 and H97), which will support the fresh SATA Express standard, bumping transfer speeds to 8 or even 16 Gbps (819.2 MB/s or even 1.55 GB/s), perhaps. The bus improvement is expected to drop ahead of
Intel's planned 14 nm die shrink
With more breathing room on the bus and fresh overclocking abilities, enthusiasts and industry performance tuners may finally have the freedom to achieve something they long wished for -- overclocking their SSD.
will be reporting live from the Intel Developer Forum in two weeks, so hopefully we'll have more details for you shortly.

Don't SSD microcontrollers have their own clock generators?
The OCZ Vertex 450 advertises a "power optimized clock generator". If this is the case then wouldn't the only thing overclocked be the SATA link.

Well the article didn't go into detail, because it seems the article was working mostly off an upcoming event press release page, versus a technical article. If I had to put money on it, knowing this industry, it will probably only be available to SSD controllers that support it. That would probably mean it will require cooperation with SandForce, since most SSDs on the market (including most of intels now) use sandforce controllers.
