Bare in mind results were done pre 331 beta bios release period.Results for 2x 512MB OCZ PC3200 Gold with the new BH5 dies. The product link is at http://www.ocztechnology.com/products/m ... annel_gold
Tips for this ram on DFI NF4 SLI-D
1. don't use 325 or 326 bios they mess up the ram clocks and threw me off track as to what the ram can do. i.e. lower cpu multipliers in 325 bios don't work 10x/9x
2. best bios so far 310 official bios
3. with 310 official bios fix ddram data drive strength = 1 otherwise you can sometimes BSOD in windows, i set drive strength at 2, 4, 6, 8 fine with no probs
4. ram with 310 official bios performs nearly exactly like old BH-5 in terms of mhz ceilings at each vdimm setting
5. like old BH-5, the new BH die stuff on this ram doesn't boot at cas3
6. Trc of 10-12 is needs less vdimm, but once you change Trc to 8-9 you need 0.1-0.2v more vdimm to get windows stability
7. ram is untested beyond 200mhz speed so guess not even OCZ know what they are consistently capable of overclocking wise from module to module
so far with 310 official bios with 2x 512MB OCZ PC3200 Gold on DFI NF4 SLI-D i'm at memtest86+ v1.55.1 wise
240mhz 2-2-2-5 at 3.0v
245mhz 2-2-2-5 at 3.1v
250mhz 2-2-2-5 at 3.2v
255mhz 2-2-2-5 at 3.3v
260mhz 2-2-2-5 at 3.5v
using stock AUTO 12-14-2-3-2-4 or 12-14-2-2-2-2 or 12-14-2-2-1-2
Of course windows stability tests will probably result or change those results somewhat.

- note SLI mode will probably reduce cpu related performance slightly so take that into a/c with the benchmark results.
