Short string versus long string in Prime..whats is the difference?

I am getting consistent short strings at 2.61 on my opteron on Core 0 about 10 minutes into prime 95(new one). I am told that could be mobo or memory related. But, I dont see how it could be memory as it memtests out fine and I am underrated speeds(ddr500) I am at ddr 470 with a 5/6 divider. Anyone got any ideas? I just would like to find out what my bottle neck is... This is water cooled also btw. Temps on the cpu <37 degs full load ~ 26-27 idle. Thanks a bunch guys!!

Anyone?

the short ones test the cpu more, the longer ones lean more on the memory. When im trying to find my cpu max I use 8k exclusively. If its just one core im going to have to say its the chip.

I think we are talking about two different things. When you have a rounding error in P95 it either reads something like .422345092340 but got .5 or..... .4 but go .5 hence short string of numbers versus a long string of numbers. Somewhere someone said they indicated different things.

Thanks,
