[Nuckin_Futs]

Nuckin - can you post all of your CMOS settings for the 4GHz machine?

I've currently got "standard" PC2-8500 in my machine (I removed the Ballistix due to incompatibility issues). Will I have any problem configuring the RAM to work with 4GHz?

Also, can you quickly explain why the RAM settings need to be adjusted to work with the 4GHz settings?

Thanks!

As for the RAM, it didnt matter so much for CPU @ 4GHz, but more of the RAM amount of 4 Gb size. But the timings need to be adjusted slightly to keep stable, especially on an OC cause more RAM taxes the MCH, making it work harder to address all that extra RAM. But when OC'd, it now has to do all that much faster. Most overclockers will not insist on populating all 4 slots as this is not the most stable for high OC, but OK if you relax later after stable for real world work. 2 slots is best, but 2x 2gb kts are OK if you relax them just enough to keep up. It is still an addressing issue but not as much a vdimm tax on mobo and chipset as 4x 1gb kits.
