2GB OCZ PC3200 Performance + DFI NF4 SLI-D

[eva2000]

This memory is pretty old on P4 platform did 230-238mhz 3-3-3-8 at 2.65-2.8v vdimm. Now on AMD64 let's see

System:
3200+ CBBHD 0445 VPMW water cooled
DFI NF4 SLI-D 414-3 official bios
2x eVGA 6800U PCI-E SLI mode with 71.89WHL drivers
120GB WD 1200JB
Pioneer A05 Burner
650W Silverston Zeus ST65ZF PCI-E SLI psu
WinXP PRO SP2

- note SLI mode will probably reduce cpu related performance slightly so take that into a/c with the benchmark results.
- Tref of 0388 was the key to stability with 414-3 bios while 0648 was key for stability on 310 official bios both bios resulted in same max 225-230mhz 3-3-3-7/8 at 2.8v. With wrong Tref set test #3 in memtest would error once or twice every few passes.
