The slower clocked CPU runs cooler and more stable, making it ideal for a server environment. think this is what TheSubtleKnife is getting at, not the RAM timings, lol. RAM timings are a property of the RAM, not the CPU. Even tho the Memory controller is built into the K8, lower timings will only affect stability of the RAM, not the CPU. If you have RAM that will cope with the timings at the correct vDIMM and SPD timing values it will run fine.
Think that clears stuff up. Maybe I misunderstood. Please clarify if anything I said was dubious!
No, ram timings weren't ever involved in this discussion. I believe he's referring to the fact that an Opteron and a X2 at equal clock speeds will not perform identical. AMD has refused to comment on why this is, but there are only 2 possibilities since the chips are manufactured the same. Either the IMC has it its timings relaxed or the caches have had their timings relaxed. Both will affect performance in a negative way, but will increase stability and the ability to overclock.
