Only started testing the 3200+ 0518 APDW and the memory controller ain't anywhere near as good as my 4000+ san diego (i.e. 2x512MB Gskill PC4400LE on San Diego can manage at least 300mhz 2.5-4-3-7 at 2.8v for memtest and benching, but with 3200+ Venice errors out immediately in memtest86+ v1.55.1 but still have to retest the ram properly over next few days.)
* The venice's cpu stability is even more closely tied in to memory controller/mem stability than previous winnies/clawhammer/sandy cpus I've had.
* Using my Gskill PC4400LE i had to throw out all known stable timing/settings on my other cpus and start testing from scratch with my Venice. Tref, Drive and Drive data strength can get very unstable at some settings so have to retest them all as well.
* Right now superpi 32M is fine at 2750mhz at 1.58v and stock vcore fine for up to 2550-2600mhz for pifast and 2663mhz at 1.53v.
* But memory timings play such an important part to stablize this Venice as i loosen timings further i get more stability at higher end! It's going to take alot more time to find stable mark as i have to retest from scratch Gskill PC4400LE settings then test cpu for stability.
* Different bioses gave me different stable points with cpu and ram - tried 510-2, 510-3, 414-3, 414-2 and now 310 official which seems best for cpu stability.
System
3200+ 0518 APDW water cooled
DFI NF4 SLI-D 310 official
2x eVGA 6800U PCI-E SLI 76.10
2x 512MB Gskill PC4400LE orange slots
120GB WD 1200JB
650W Silverstone SLI PSU
WinXP Pro SP2
NF4 6.53 remix chipset drivers
- note SLI mode will probably reduce cpu related performance slightly so take that into a/c with the benchmark results.

Not the best venice, but not the worst either
