So prime95 is majority of the time only allocating 8GB for P1 Stage 2 when I've seen it using 1213GB before after I re save the local.txt memory requirements to use the 12/13GB. What am I doing wrong?

If it is more than one then the total allocated to all workers will not exceed about 95% of what you have specified in local.txt. 8G will still get you at least a third of the Relative Primes for one Stage 2 which will be very efficient.

You'd probably see better thruput with 4/1 or 2/2.
When it allocates 8GB does it process ALL relative primes? For example something like: Code:
[Oct 19 11:18] Available memory is 14000MB. [Oct 19 11:18] Using 8000MB of memory. Processing 480 relative primes (0 of 480 already processed).

This is a laptop and worried about cooling, this is a better option for me.
Yes but now looking closer I can see when it needs to process 960 relative primes it uses 12GB. We are fine anyway....it is the first time I taking more time to look at client's logs. Thank you indeed.

I've started ECM on the suggested range. My first set is 5 curves at B1=250K; I may adjust that later. A curve at this size on the Surface tablet I'm using takes about 25k seconds, so ought to progress at roughly 5 candidates per week. I'll give it a couple weeks to start.

My progress is slow: 35/100 done, two factors found.

Some ECM highlights: M14099401 has a 89.780 bit factor: 1063184393209412095691752279 M14017981 has a 88.926 bit factor: 588003375432513022023853873 M14006803 has a 83.617 bit factor: 14830679176132537433148793 M14005253 has a 77.906 bit factor: 283076393615085922807961 Some P1 highlights: M14018573 has a 105.648 bit factor: 63580734348894934266923905132639 M14057863 has a 98.809 bit factor: 555219273599892685265834731087 M14010797 has a 80.792 bit factor: 2093252408084980613260481 One TF highlight: M14079067 has a 71.198 bit factor: More ECM would have found this, I think It will become harder to find factors, so I'm happy to report that we have gotten some help lately from others on the forum. Many thanks! Last fiddled with by masser on 20201025 at 14:19

Your factor rate is good; I expect about 1 in 30 attempts.
If you want to see if LapTop heat is actually impacted you could try 2 workers / 2 cores each. You'll get better thruput and maybe without extra heat. I say that because in your setup (1 worker 4 cores) all 4 cores are still working hard. Thanks for any and all contributions
