Just a quick question as I haven't been able to find any other questions regarding this...

I'm running BOINC 5.2.13 and an AMD 64 FX-53 with 1Gb of RAM and have approx 200Gb of HDD space free.

I'm averaging 95 Avg. Credit. Would you guys consider this normal for this spec? If so then fine, but if it seems slow then are there any suggestions for me to increase this?

Hard to tell - so many things come into it, including how many hours you have the PC running, what share Rosetta gets, whether you're overclocking, how long it has been running Rosetta, how often you return results, etc. Plus of course, what else you do with the computer (BOINC runs at low priority). RAC tends to build up over time until it gets to a plateau.

In the early stages, you may be better off looking at how many credits you are actually getting per day, at one of the stats sites.

By way of comparison, My Athlon 64 3700+ (San Diego core, overclocked to 2.7GHz, in effect an "FX-56") is capable of about 350-370 credits a day if I run it 24/7 on Rosetta but I switch it off overnight, so it only gets about 270 a day.

I compared some of your results with some of mine. Your claimed credit seems _slightly_ low, maybe a few percent, given your computer is probably a bit faster than mine. (3700 but not overclocked as much as Yoda's) This could be just because of benchmarks running when it was doing something else.

Your times per result look within reason. You have more "long" results than I do, but then it's pretty random, there's no way to do a direct comparison. (Insert wish for Rosetta to provide a "reference WU" here.)

You started returning about 7 results/day "regularly" just 2 days ago, before that you were doing them in blocks; a bunch of results, then a couple of days with none, then another block. I'm guessing that Rosetta has about 2/3 share on your PC, based on adding up result times, and that you should be able to get around a 400 total RAC pretty easily with it, so I'd expect your Rosetta RAC to be close to 300. That will take about a week though, if you continue at the current pace. If after a week, you're still at 95 (and I'm right about the 2/3 share) then I'd look at what might be causing you to run slow. (Cool 'n Quiet would be my first guess on an AMD...)

RAC moves slowly, both up and down. Also, IMHO, the 3rd-party stats sites do a better job of calculating it, and quicker, than the projects do; that goes back to the BOINC server code.

Crimson, as the other said, you could always go to boincstats.com and check your rac there - it usually represents what your rosetta rac will be in a few weeks time. Took me about one month for my rosetta rac to equal my actual rac, so I wouldn't worry about it too much until then if I were you.

Thanks for the help guys.

I went away for a few days at the end of last week so my pc was off during that time so i guess that has done something to the figures.

Anyway, i'll leave it as it is for the time being. Will just see how it goes.

Look up RAC in the Wiki, too much to re-write here ...

BUT, I have to tell you that RAC is VERY time sensitive. Even more so on the project sites as the updates happen all the time. The stat sites only recalculate the RAC when new stats are received. So, the interval is "constant" and this makes for a better behaved RAC.
