Necessay RAM for factoring
I don't have enough money to make a difference if I were to move out, but I so seldom get a chance to make a major purchase I savor it when I save up.
1.75GHz Sempron and I would like enough RAM to factor numbers in the second step at least until they get to n=15 million.
DDR-SDRAM
Frequency 166.5MHz
2.5-3-2-7 latencies
(512MB at the moment)
advice welcome, including future-proofing advice)
Confused on B1 & B2 settings
I'm a novice...just an interested computer user who hates to waste computer cycles...and likes a little math.
I followed the download and install directions. After several days I looked in the fact.txt file and noticed that something didn't look right.

21181*2^10860020+1 completed P-1, B1=35000, Wc1: 18FCB560
There was no B2 stage. I played with the Prime95 settings and discovered that if I changed my memory, the program started B2 testing.
I then read this thread and started playing with memory settings. I'm at 120MB and B1=60000 and B2=540000. Is this appropriate?
Also, as I was about 3/4 through the range, should I redo the range with the new settings?
