Sorry if this was already asked, but will geting more memory(512mb more then my current 256) raise my recent average credit by much?

It's doubtful you would see any difference in the boinc projects at all.

seti@home only uses about 16 MB of ram. Climateprediction can use up to 50. The only way it might help you is if your current memory is overloaded so that the OS has to swap some of seti@home's data out to disk. But even then it probably won't make a HUGE difference... 256 is getting to be a little on the low side these days so an upgrade might be in order regardless of BOINC depending on what you use your computer for.

It appears that you're running Windoz XP, and that will benefit from more than 256mb no matter what you're running.

Enjoy!

*EDIT* Although, 512 total should be sufficient for all but the most demanding applications.

Like the others have said, it won't help to have more crunching speed
but it would help your windows overall performance. I have been very
impressed when I did upgrade my laptop from 256 to 512. The biggest
improvement I have noticed was when quiting a demanding game or
application. The windows desktop comes back twice as fast.

If you're using yout PC just to send emails and stuff, 256 should be
enough, but if you are into games or working on large video or
whatever files, then you would enjoy having 512 + of RAM.

Marc

If all your doing is crunching, a little email,And your favorite recipies then 256Mb should be plenty.Windows suggests 512Mbs
If you plan on running some of the newer games for instance whle running Seti then an upgrade is best.
Alot of newer programs, especially Games,Run best with at least a Gig Some as high as 2gig.This allows enough space to run Apps and services plus programs.

Mixxster,

While it may not increase the rate at which you accomulate credit on the BOINC-based projects, the cheapest speed enhancing upgrade you can add to your computer is RAM. The main reason for this is the more RAM you have the less your swap file is accessed. Accessing RAM is a whole lot faster than accessing your hard drive.

Cheers,

OK, thanks people. But I know what RAM is. Im not that dumb (afterall I did build my own computer). I guess I just needed to know what the maximum amount of ram that SETI uses.

just adding more RAM, I guess it will give an overall gain (due reason metioned) of about 1% perhaps 3%, for SETI.

may I place this:

a while ago, on seti classic. a host was a 2.66 GHz pentium with 256 MB RAM, with the RAM speed of 266 MHz.
I added an other 256 MB, now total 512 MB, still ram speed 266.
No crunchtime difference. (XP Home)

The ram was removed and replaces with 512 MB (same amount) but ram speed 333 MHz. The mainbord was SUPPORTING this higher memory speed.

The result is (values from seti classic)
with 256/512 MB RAM DDR 266 about 3H 15min to 3H30min

with 512 MB RAM DDR 333 2Hours 45min til 2Hours 55 Min.

so you see, in MY case, with THIS mainboard, the more gain could be done
by adding FASTER RAM, not only more RAM.

At your place, before upgrading anything, first check 2 things:
-1- check if you already RAM can't run with shorter memory timing setings (from 3 to 2.5)

-2- what is the mainbord supporting? DDR200 /DDR266/DDR333

goodluck!

Not only can youo get faster RAM, but at times with some of the new motherboards you can also get two channels working which also increases your speeds.

If you are planning a new system, or thinking to have an upgrade, there is little reason to have as low as 128M, 512 is much better, with the fastest bus speeds, and the fastest access speeds. you are better off.

When doing multi projects with BOINC, having more memory allows more to stay in memory when you swap out to the alternate projects.

True, but dual channel memory systems generally only provide a 2-5% improvement in performance with most programmes.
With some programmes it can be as high as 20%, but they're not that common.

I got two 3.2 GHz processors and one of them I put in a higher class (more expensive) MB with dual channel memory and slightly better sticks.

If you look at my computers you can see the one with the dual channel memory (two Corsair memory sticks) is doing a RAC of 145 (EQ-1). The same class processor with more of a "house brand" sitck pair and no dual channel memory is doing 132 for the RAC (P4a-3200-ht).

So around a 10% improvement; better than most, not as good as some.

I did notice that when I ran Boinc non-stop, my sytem became a little sluggish when using some other aplications. So I decided to upgrade my RAM. I just put in a 512M next to my original 256M. Right away I noticed improvement!

One question though. Which one should I put in the first and second slots? Does it make any difference?

Thanks for the advice!

The Bigger one ALWAYS is closest to the cpu, Some MB are marked I and 2,(Check manual for illistration)
make sure they are of the same type i.e. ddr 2100, 2700 etc. properly done both ram sticks should be the same size and type. Unbalenced ram loses a little bit in performance...

This is one of those "it depends" ... on my Macintosh and on EQ-1 for example, you buy the RAM in sets of 2 and one goes in one bank and the other goes in the other bank, but this is for a MB that has dual channel ...

If it is a low-cost, older MB, then as stated earlier, it does not make much diference.

My "standard" machine gets bought with a Gig or more. My current Mac has 2.5 G and for daily work when I look I ususlly have 1 to 1.5 G free. But, the cost was not that great, so I did it. If this Years Mac can't use the same memory then I will buy it with at least a Gig, then add at least one more later when I have saved enough.

Most OS love extra space. In *MY* rules for buying a system, you buy it with the best MB and CPU you can afford, skimp on all else. RAM, Video card, etc. can all be upgraded later. Many times you can move items around for a long time if you buy quality. For example, when I got rid of 4 PCs, brother Tom got 2 and parts enough to beefup a couple of his systems.
