No errors with previous science apps. In each case the other two apps were one each of 4.37 standard, and D40. Stick's invalid WU has the same combination of science apps as well.
so then the general concensus is that S40 SSE is better for your AMD chips than the D40 with 3DNOW!?
>I switched our AMD's over to S40 SSE from D40 as it seemed slightly faster (1-2% range). It was more evident on the older 1.8 MHz Durons then on the newer AMD's though. Larger cache sizes on the newer machines may be a factor here...hope this helps.

My first result with S40.03 finished successfully, but was not granted credit - not sure why/how this happened. Any ideas?
EDIT: That is, if my result was invalid, then why wasn't the WU sent out to another host (to get the third valid result)?
Nothing is wrong. There were three successful results. The validator compared them, found that two were valid and one was invalid. End of story.
Hi Bruce!
I hope the number of invalid wus will be reduced by spreading of the new official application.
Comment: I checked some modified routine. They calculate some parts in a more precise way than the official (less and better rounding), but they also give differences at validation, of course. So, a "0.00 credit" doesn't mean that the result was worse.
Switched back from S40.03 to S40 on my AthlonXP 2600+ (T.bred). S40 seems to be a bit faster (about 3%).
For AMD's 32-bit CPU's I'd recommend S40 if SSE capabilities are present, otherwise D40 for 3DNow! capable ones. I've tried them all and found those to be the fastest ones.

The relative accuracy is worse than error limit.
E1 is good, E2 is good, but E1+E2 is not.

I quote myself
Time is stable with a wu r1_1220.0__xxx_xxxx : 3,723.23 sec -> 3,746.73 sec.
Is it possible to reach the 3,600 sec mark ?

Here is one of many that one of my 3200+ has finished. Note the cpu time in the real_cpu_time field.

strange, but for Athlon XP 2600+
first 3 WU on S40.03 work slow S40 about 4 %
and now i using S40 on Athlon XP...
