JEDEC Sets SSD Standards

"As with most flash products, the JEDEC wants to make sure SSDs are up to spec."

When solid state drives (SSDs) were first released for the mainstream market, one of the biggest concerns of consumers were their stability and longevity.  The known write cycle limits of NAND flash memory made people wonder just how reliable the drives were.  While we've now gotten to the point where the technology has matured enough for this to be less of a concern, the JEDEC hopes to ease the fears further.

Late last week, the JEDEC announced the publication of the "JESD218 Solid-State Drive (SSD) Requirements and Endurance Test Method" and "JESD219 Solid-State Drive Endurance Workloads" standards.  Created by the JC-64.8 subcommittee, these standards dictate things such as overall total data written and workload specifications SSDs must perform to for both consumer and enterprise applications.

"Standards play a critical role in technology adoption and proliferation, and we are glad to have participated in development of the JEDEC SSD standards. The comprehensive approach taken to defining capacity, workload and endurance will go a long way towards enabling market confidence in SSDs,"said Scott Graham, Vice-Chairman JC-64.8 and Technology Strategy Manager, Micron Technology.

"Solid State Drives will change the system architecture for compute applications due to their disruptive value proposition in Enterprise and Client Compute Applications," added Steffen Hellmold, VP Business Development at SandForce. "JEDEC has taken a leadership role to bring the industry together to enable broad market adoption of SSDs through industry standards with the announced standards representing a significant milestone."

More quadfire shenanigans :D

So having ruled out power as a problem I tried running the exact same config in the Asrock as I had in the Crosshair II. And, the same thing happens. No display, continual fan and LED looping, bottom card freaking out.

On Friday evening I sent an email to that guy from Asrock (who sent me the beta bios for X6). Today we have exhanged a lot of emails and he thinks for 99% definite that the board should definitely run the two cards together. He also said that he would get onto the main offices in Taiwan and instruct them to find the answers, and, if needs be fix the bios (which we are both pretty certain is the cause of the issues).

Here is a video running a single working card. Note the fan pattern. When it goes down in speed I get a signal and post.

Blue light is the Physx PPU.

And here is what happens when I try and run two cards. Listen to the noise and watch the LEDs. They are in perfect timing with what the fans are doing. Note that the top one is a completely different pattern to that of the bottom one? This is the super Scooby Doo mystery.

Interesting eh?*

*OK, maybe not and maybe I am really boring you all with my super geeky addicted to hardware thing :D

Surprising how you got so much support from Asrock. Seriously.. hats off to these guys.

Well they never got back to me. Personally I think the PCIE lanes did not have enough power to feed the cards. Either that or the ampage on my 12v was not enough to feed both the cards AND the lanes. On the Asrock it needs a molex for the PCIE lanes.

Fair play though. I mean they have to draw the line somewhere I guess and it is knocking on 6 years old :D
