[QUOTE=garo;194804]Have you tried using it with throttle? Even half the output is better than none.[/QUOTE]

It has now "survived" for 12 hours at 50% Throttle.

PIVs are very bad at TFing to low levels. That´s because the SSE2 optimizations won´t kick in below 64 bits. If you use a PIV for TF make sure you start at 64 bits. PIIIs and AMDs (Athlon, Duron) are good at low levels.

That verifies a recent observation.
My PIII 866 can do 83M exponent 63-64 bits in 1 hour.
My PIV 2.4 takes 25 minutes - just over double yet for a DC or higher bits of factoring it is closer to 6-8 times as fast.

If I upgrade I don't plan to use it for LMH.

Right.
I suggest P-1 work. I have a PIV 3200 (Northwood core) with 2 GB of memory that used to work on LL, and later on DC tests, but recently I have assigned it to P-1 factoring and is doing pretty well. Allocating 1200 MB (daytime) and 1700 MB (night time) of memory, it returns a result every 2.5 days, with a probability of success about 5,9 to 6%.

The PIV 2.4 Ghz only has 512M RAM. I ran a few P-1 allocating 400M and it took it 4 days for a 51M P-1. However, with so much RAM on P-1 if I ever needed to do anything else on it , it was REAL sluggish to get going.

4 days for a 4 point P-1 = 1 PPD
14 days for a 18 point DC = 1.3 PPD
26 minutes for a .0235 63-64 TF = 1.3 PPD

Do DC or factoring in the 65+ range. I'd say DC as it is underpowered and TF overpowered.

Got your point. Go for DC, then.

DC is where I actually have settled with that PC

... Just not Washington :-)

[QUOTE=markr;191697]On to 83M.[/QUOTE]

Forgive me, I just took the last 50 in the 83M range.
I'll be done in 2 and a half days.
Nothing left unassigned below 100M now.

On another note, if all goes well and I get my new quad build this week I may be cease and desist these special low bit ranges :cry: though I still have a Duron that is best suited for this work but it is not very accessible so unless things change...

Thanks, it's been fun.
Watch for me though in other work types.

Thank you too - it has been a fun journey.

So 83M is just about done to 2^64 bits - another milestone! This range was done more quickly than 80M: less than two months compared to three or four. There was more firepower, from various people, which is good![QUOTE=chalsall;190083]We're all working towards the same goal, aren't we.[/QUOTE]

At the rate some BIG guns are factoring (i.e GIMPS Visualization, et al) there may not be any work left below 64 bits in a few months :cry:

Are you planning to continue above 100M now or start a new "project"?
"you" in this context can be any that have been collectively working in this <100M range.
