venice e3 vs e6?

so i've been googling like crazy to find out the difference between the e3 and e6 revisions on venice cores. all i could find was some page in portugiese (sp?) which i managed to babelfish to:
e6 is compatible with more memory, specifically 533mhz

is this it? are there any differences in heat output, c'n'q performance or any of the stuff that we actually care about?

regards, kent.

No. Supposedly E6 steppings had some improvements to the memory controller and fixed a couple of unnamed bugs, but for the purposes of most SPCRers they are identical.

E6 fixed these bugs in E3:
* #113: Enhanced Write-Combining Feature Causes System Hang
* #114: DDR Data Pin Drive Strength Also Affects Command/Address Pins
* #116: DDR Chip Selects Tristated One Clock Early in Power Down Mode

E6 is also compliant with the new EU Environmental Production Standard (basically lead free electronics, etc)

The main difference is that more chipsets can use the E6 than the E3's. However there is zero impact on performance.

How do you know this? Are you on the AMD chip design team??

I must have googled for like an hour and I didn't come up with any information nearly as detailed as that. Let me guess, it's somewhere blatantly obvious on the AMD site....

I looked into it when I was buying my PC last year (right when the E6's were coming out). I belive I found the information in one of AMD's errata documents. But for this post I just searched for one of my posts on a different forum.
