What kind of Halloween you run and how long does it take to find a zombie
 

I run
i72720QM
CPU Speed: 2192.14 MHz, 4 hyperthreaded cores

The estimate is around 15 days to complete the smallest available first-time test. What are you running, and how long it takes to complete the assignments ?

re: Headline- it takes a really, really long time to find a mersenne prime. Best wishes this lifetime.

As for time to run a single test, try mersenne.org, menu choice "get started" then "cpu benchmarks".

Was just wondering about the status that we get from Prime95. My status shows Lucas Lehmer test will end after 15 days. Regardless of whether the exponent results in a prime, I was more interested in how quickly people are finishing the LL test.

Core i5 4670K, 11 days for a 64M exponent

i5-4670k, just under 5 days for a 64M test if all 4 threads are used on one test.

Hmm, I wonder how accurate Prime95's "Time" function is.

No, that exponent isn't mine, I picked it up and dropped it just for testing.

How did you get it to show ETA within the main screen like that?

Dunno, you have the latest Prime95? It comes up automatically for me.

I have version 27.9.
Was trying to decide if I wanted to update to the latest version. I only have Sandy-Bridge and not Haswell.

I have 28.5, that's probably why. Why not? :smile:

There are some small performance improvements in 28.5 for Sandy Bridge, too.

Okay. So when I upgrade and I am supposed overwrite the previous version... Do I just change the name of the location I am unzipping the file to so that it is the name of the previous version of P95?

The default location is C:\Users\Kyle\Downloads\p95v285.win64.... should I change this to C:\Users\Kyle\Downloads\p95v279.win64 which contains the current version (and then just rename the folder)?

I know this is a dumb question but I'm a little bit paranoid about losing progress as I have an exponent that is close to finishing.

Yep, that will do it. To me, Downloads is something like a temporary directory. I'd suggest that you move it from Downloads to a more "permanent" location, so that e.g. if you want to free up space by deleting unused downloads and do Ctrl+A->Delete, you won't accidentally delete your working Prime95 files.

You can copy/paste the entire directory for a quick backup.

Just replace your Prime95.exe (or whatever the Windows executable name is) with the new one. Don't overwrite any of the other files as you may lose your settings and work in progress.

p95v285.win64.zip contains only:
[CODE]license.txt
prime95.exe
readme.txt
stress.txt
undoc.txt
whatsnew.txt[/CODE]
You can overwrite all of these files without losing any work: they are all static files (by which I mean, they do not change as you get, run, and complete work). You do, of course, want to exit Prime95 before beginning the upgrade, so that you can overwrite prime95.exe. I'd agree that you should not overwrite any [I]other[/I] files, since they are probably generated ones, and modifying them might make you lose your work.

Update was completed successfully. Thank you. The jury is out on whether or not it has resulted in a speed boost.

You're right. I was wrong. Thanks for clarifying that for Primeinator!
