System tweaks to speed GIMPS - Page 4

Every windows 2000 or XP user should check out www.blackviper.com

this guy has gone through and documented all the services being run and shows what is safe to kill and what isn't. My speeds have dropped from .123 to about .099 or so. If your not gonna be using your computer for a while you should use the "gamer" settings

i have prime setup to run as a services and make sure to log out at night so that no other apps are running

that doesnt really speed prime up as much as it keep it going at optimum

along time ago i heard something about loading prime into a ram drive helps speed it up slightly

i may try it since i have a gig of ram now.

ill let you know if there are any improvemetns

also i dont know if anyone mentioned running prime in safemode may help becuase it doesnt load anything else and also doesnt put much strain on the systems video or audio needs

You should get better times in Safe Mode, except if you have an HT enabled P4, then it actually runs slower in Safe Mode.

See my regular and Safe Mode results here:

Wow, that site is good. I only do TFs but I think I shaved a few seconds off per 1000 iterations. Very nice.

Starting at this page, firingsquad shows the effect of additional DIMMs in a system. Up to (what I've seen so far) 60% slowdown for a system with 2GB versus a 1GB setup. On average the slowdown is less - something between 20-30%. That depends on the number of installed modules and AFAIR, registered modules don't suffer from this effect.

So if there is for example a dual channel setup and I'd need lots of RAM I would chose the biggest modules, which still don't have an exaggerated price level.

I can't get to this website. I can resolve the www.blackviper.com to 209.233.13.118 but I do not get any page in my browser.... Is this just me/my connection or does the site have a problem?

PrimeCruncher · 2004-01-14, 03:24

Seems to be an issue with the site, I can't get thru either.

patrik · 2004-01-14, 22:34

Works for me.

PrimeCruncher · 2004-01-14, 23:03

It's working again now.
