Hey Blankman,
Well... OC Profiles are good for when you discover a good overclock and want to save it. Nobody hosts profiles because they are meant for personal use, and all computers will vary.
For 2.8GHz, I highly recommend water cooling. Don't bother if you don't because it will not likely be stable. Here are the settings I use most of the time:
2.75GHz (275HTT * 10, 1.45v) Multiplier, DDR2-800 selected.
- DDR2-800 4-4-4-12 1.9v 1T (2.40GHz 1.25v)
- DDR2-900 4-4-4-12 2.1v 2T (2.70GHZ, 1.45v)
- DDR2-1000 5-5-5-12 2.2v (2.50GHz, 1.45v)
- DDR2-1000 4-4-4-12 2.2v (2.50GHz, 1.45v)
- DDR2-1100 5-5-5-15 2T (2.75GHz, 1.45v)
The italicized ones are from my recent A-Data ram review. To have DDR2-800 speeds with your memory, you will need to play around with that setting (Advanced > CPU Config > Dram). Overclocking is a game really, you just have to keep trying until you figure out something that works.
"2GB of the 800 Mhz twin x2 6400 from Corsair."
Do you mean you will have 4GB worth, or just 2GB? I have similar modules, but the Pro version, and they overclock to DDR2-1000 speeds without a problem. So, if I were you, I would try these settings once you have the memory:
250MHz with 10x Multi... for 2.5GHz. Set the DDR speed for DDR2-800 and choose 4-4-4-15 timings. Select 1.35v for your CPU vcore, and 2.3v for your vdimm. This will give you 2.5GHz with DDR2-1000 memory.
or
225MHz with 12x Multi... for 2.70GHz. Set the DDR speed for DDR2-800 and choose 4-4-4-15 timings. Select 1.40v for your CPU vcore, and 2.3v for your vdimm. This will give you 2.75GHz with DDR2-900 memory.
