2 Noob questions
 

So I thought I'd let my PC tootle away doing some prime searching.
Hey, why not, would be fun to be the discoverer of a really big prime number right?

So anyway, my current workload is 23% done, been running for about 2 weeks.
And it claims it'll be done on March 12th 2013. Is that right?
Seems a long time. I have an i3@3.6ghz

Also I have 8gb of RAM and have told it to use 6gb at all times, but the memory usage monitor on my PC states that only 1.8gb is being used and I suspect most of that is the OS.

Anyway, just wondered if these things were right or if something's set up wrong somewhere?

Cheers

What's your exponent range? (how many millions large?)

Are you running only a single number or multiple numbers? The date should fall.

The memory amount is only during part ('Stage 2') of P-1 testing. There is a good likelihood that you are not doing that. Right now most 'First time' numbers to be tested have already had the P-1 done. See [url]http://mersennewiki.org/index.php/GIMPS_type_of_work[/url] for more information.

Ok, I'll try not to embarrass myself too much.
But the only setting I can see that says 'exponent' next to it is under Advance/Time and it says 38,000,000 with 10 itterations... is that it ?

I also have 2 workers going.

In the worker windows it should say what numbers you are testing.

You mean M29995577 and M29995751 ?

If those are the exponent you are testing, then something might be wrong, or either the computer is only occasionally on. For a i3 3.6G, a 29M exponent should not take more then 15 days in a single core (that is about 350 hours of continuous work, like your computer is turned on 24/7, if not, you have to make the calculus and conclude, but for me, 4 months sounds really like a lot of time).

If your "per iteration" time in the worker windows is around .020-.050 seconds, then it's running properly.

Is this a pre-Sandy Bridge i3?

Edit: LaurV and I cross posted, but you can see why I'm asking what generation your processor is. Are you sure it's 3.6 GHz? Did you overclock it? How many cores are there? Best yet, do you have the specific model number?

It's probably not Sandy Bridge, (no avx)

I've done a smidgeon's worth of research on the Intel website, and having looked it seems that the i3-570 at [B]3.06GHz[/B] is the CPU that you have - either you're overclocked or have a different chip. Other than that, you have a Nehalem chip (Q1, 2010) - which does not have the PFR (Physical Reg File) enabling AVX to work for integer and floating point.

Yeah it's the 3.06ghz CPU but I'm given it extra 'oomph' and fast memory :)

Let me see..... off the top of my head, I'll say the PC is running Prime95 4-5 hours a day in the week and 26 hours in total at the weekend.

My 'per iteration' time is around .031 and the longer I keep it running, my estimated time IS falling. It's currently May 10th. And at the rate it's falling, I guess it should be done around early Feb.

So is this still ok ?
