Intel to Demo SSD Overclocking at IDF 2013

It could soon become possible to overclock the controller and NAND flash of your SSD, if Intel has its way. The company is set to demonstrate how to overclock Intel-branded SSDs using its Xtreme Tuning Utility (XTU), at IDF 2013, which goes underway this September. The item on Intel's IDF itinerary marked "AIOS001" deals with seminars on overclocking Intel's next-generation HEDT (high-end desktop) platforms. X-bit Labs believes Intel could talk about SSD overclocking during that session.

Options to tweak SSDs were discovered when poking around the code of an unreleased XTU version. XTU is a unified software utility by Intel, which lets you tweak CPU, memory, and system cooling on systems running Intel Desktop Boards. Among the things end-users should be able to tweak, apart from the controller clock-speed, are the NAND flash bus-speed. Taking away interface overheads and other round-offs, 560 MB/s appears to be the practical maximum bandwidth SATA 6 Gb/s SSDs have been able to achieve. It could always be handy getting your SSD a few dozen more MB/s sequential speeds at the expense of stability.

Since when overclocking the pci-e bus is a good thing? The last three intel cpu generation (sandy, ivy and haswell) are all limited to 5-10% max bclk variation, mostly because the pci-e bus really doesn't like to be set at anything but 100 mhz.

And i don't think the pci-e will be the bottleneck, as to this day nothing comes close to saturating a pci-e 4x slot! (and don't tell me that 20 ssd in raid 0 can, you'll just prove my point...)
Wrong. Haswell allows up to 166 max BCLK. But that can cause PCie instability if you do not tweak it right i'm pretty sure.

Not talking about bclk straps (100, 125, 166 and 250 iirc), but the tolerance of the bclk when using any given strap: the same 5-10% max variation from "stock" value ( something like 155 to 175 mhz when using the 166 strap, for example) applies.

And i'm pretty sure when you're using say the 125 bclk strap, the pci-e bus is still running at 100 mhz...

imo , intel has extremely strong guidelines and quality assurance . Im sure they wont release a faulty product that doesnt last long . Maybe they have something up their sleeves .
But theoretically i do agree with everyone that over clocking or increasing the performance of said "data" is unethical in todays technology ,but before we jump to conclusions i think we should wait and see ..
