There have been some questions as to which B1 and B2 values to use. One option is to always use the Prime95 default. Currently those setting should probably use a sieve of 52 and a value of about 1.7 per test. The 1.7 is my opinion.
Others can chime in with what works best...
The other way to look at it is setting B1 and B2 manually. Ideally equal time should be spent in stage1 (B1) and stage2 (B2), although stage2 is quite memory dependant and it may not be possible with only 512Mb of ram. In order to get equal time the ratio between B1:B2 should be about 1:14 if memory serves me correctly.
Simply adjust your ratio until you get equal times.
-------------------------------
A good choice of b1 is somewhere between 30K and 80K, if your much outside this your probably wasting time.
Using a value of 60K is probably about right, I'd suggest staying between 50-70K.
Then choose a B2 value so that you don't run out of memory.
No larger than 14x the B1 value and no smaller than 8x.
Example
B1=60000 B2=480000
or if you have enough memory
B1=60000 B2=840000
Just watch your task manager for max memory usage.
