if Venice is the replacement for clawhammer, why does it have 512k L2?

Abeit it wasnt stable atleast with the Venice cores (ie E0 in general) the sub-zero issue has been fixed. Btw Venice is confirmed to work on both DFI's Nforce4 and MSI's K8N neo2 Platnium

So is it true then that the Athlon 64 Rev E CPU is really the "Venice" core we are waiting for ? ( Next progression from "Winchester")

Enhanced Integrated Memory Controller
"Every time a new Athlon 64 processor core come out AMD engineers continue tuning up their integrated memory controller. Note that this is done not only for the sake of increasing the processor performance, but mostly in order to extend the compatibility of this memory controller with the different DIMM modules and their configurations. The previous 90nm Athlon 64 processor core aka Winchester had certain performance limitations when four DDR400 SDRAM modules were used. If there were four single-side DDR400 SDRAM DIMMs installed in a system with a Winchester based Athlon 64 CPU, they could only work with the 2T timing, which caused a few percent drop below the usual performance level. If there were four double-side memory modules installed, DDR400 SDRAM would not work at all and its working frequency would automatically drop down to 333MHz.
AMD engineers promised to eliminate this problem in the new Venice core and they did keep their word. Athlon 64 processors based on Venice can work with four single-side DDR400 SDRAM modules without any limitations, and if there are double-side DDR400 SDRAM DIMMs installed, they can work at 400MHz with 2T timing.
Besides wider compatibility of the Venice?s memory controller, it also got noticeably faster. Among the tweaks implemented in Venice we should definitely point out enhanced hardware data prefetch and more write combining buffers (4 instead of 2).
All these improvements should help Venice based Athlon 64 processor to outperform their counterparts based on the older core revisions but working at the same clock frequency. And the performance gain will be more noticeable if there are four memory modules installed in the system."

So, even though 4 double sided DIMMS would require the system to run at 2T, there would be less of a performance hit than usual? I hope so. I really want 2GBs of RAM in my next machine.
