Run a copy of prime95 for each core the chip has in stress testing mode for at least 24hrs. If you get any errors it's not, if you don't it probably is.
Honestly you have areasonably good chance of getting it that high, but the actual OC performance of any given chip cannot be predicted in advance.
Most likely yes. I got an E2140, currently clocked to 2,8GHz at 1.275v, stock volts is 1.325v and at that point its good for a bit above 3GHz. Chips can vary from week to week and fab to fab, the only way to be somewhat sure is to look for a batch number that other people had success with, and that can be quite difficult. I was lucky when i bought my Xeon3060 and found one of the batch numbers i was looking for that other ppl had managed to OC high on low volts (it does 3.25GHz on 1.2 volts)
266x10 or 333x8 is virtually same performance, very small difference in real world benchmarks. An FSB of 266MHz has an effective speed of 1066, in theory you then dont need to move to 333MHz before your RAM exceeds DDR-1066 speeds. Lower FSB means less strain on the mainboard/less power consumed by the chipset, not many watts but could be an factor for some people. In addition, some mainboards, among them some value Asus boards, automatically change the northbridge timings when increasing the FSB above 333Mhz, that eats up the already very small performance advantage. 266 with tight timings can be better than 333 with loose timings.
Different story on more high end boards, then you can gain a little memory performance by forcing the northbridge to run at 200 or 266MHz strap and then increase the FSB as high as you can. I dont think your board has the option to force straps, but if it does then the higher FSB option is slightly better.

Thanks.
For use at einstein and Seti, will it be better at (333.33*8) or (266.66*10)?
