JEDEC Chair Says Enhanced Performance Profiles not yet Submitted
Legit Reviews has just received an e-mail from a number of sources where the Chairman of the JEDEC SPD Task Group talks about the recent announcement of EPP memory by NVIDIA and Corsair. On Monday Legit Reviews wrote up a piece titled “DDR2 Memory: Enhanced Performance Profiles (EPP)” and it seems this article and the press releases from a number of companies didn’t make the JEDEC council too happy. Today the chairman of the JEDEC SPD Task Group spoke about EPP and let the industry know what JEDEC’s stance is on the Enhanced Performance Profiles. Basically what this means is that neither NVIDIA nor Corsair submitted EPP to the JEDEC committee to become a standard. I personally contacted both NVIDIA and Corsair and was told by both that they would submit EPP to JEDEC at the fall meeting.
This week an industry announcement was made for a ?New Open Standard
Memory Specification? called ?Enhanced Performance Profiles? or EPP. This
proposal suggests that it can ?allow memory manufacturers to integrate
additional module performance data? by redefining the manufacturer?s data
region, bytes 99-127.
As chairman of the JEDEC SPD Task Group, I feel it is my responsibility to
inform the committee that this EPP specification was not developed in my
task group. In fact, we have not seen a first showing on the topic.
EPP is not a JEDEC endorsed specification and should not be misconstrued
in the industry as such. I do encourage the sponsors of the concept, or
any other companies wishing to properly document higher DDR2 speed grades,
to develop a truly open specification by submitting a proposal to the
JEDEC committee and to the SPD Task Group and following the well
established guidelines by which open standards are developed.
