No offence inferred or implied... just facts!

There is SO much headroom for overclocking these processors, it is a shame not to take advantage of it.

The best thing you can do to maximise return is to run BOINC in the background day and night continuously while you use the machine. It makes absolutely negligible difference to its performance.

I'm probably one of the greatest power users there are, often with at least 50 windows open, 20 applications simultaneously, compiling software, developing web applications, SQL programming, php editing, administrating linux machines through ssh windows, reading web news and researching while raytracing animations in the background too, in addition to the usual office stuff. All the time BOINC soaks up the spare processor cycles that would otherwise be going to waste.

There are loads of resources available for overclocking, and you should be able to get at least another 30% performance out of the machine with appropriate cooling.

Good luck,
Andy.

Hi Sir Ulli,
I also have an AMD 4400+. Mine's OC'd to 2.5GHz. I've only been a member for 3 weeks so my RAC is still climbing. Its at 760 right now. I'm also using the generic SSE2 version from the Chicken of Angnor.

Dont know what i seem to be doing wrong then in the RAC deptartment then. I have a X2 4800 and am only getting a RAC of about 522 and that with using chickens App

I get about 750 - 800 RAC with a X2 4800.

you can take a look at mine. 1 dual AMD 4400+, 1 Intel 2600 and 1 PIII 600

Hi skywatch! What about your P4 2.4GHz sistem? Is it O.C.ed? Is it running Chicken's soup?

Today my Mac Pro with two dual core chips at 3Ghz or 4 total cores over two chips clocked RAC of 4750+ per the SETI site, BOINC is a different story as it usually lags by a day or two...

@Karsten-
How did you patch the Intel-only version of Chicken's SSE2 app? I tried using the Perl script at:

http://www.swallowtail.org/naughty-intel.html but I kept getting an error:

WARNING: 10 lines were to be patched in 'SaH_5.15_KWSN_SSE2-Intel_Ben-Joe_2.0_B.exe': should be a multiple of 3! Skipping this file.

Any ideas?

TIA,
Brock

Hi folks,

my PD 805 just passed 1400 RAC using a new pre-release science app (it's overclocked from 2.66 to 3.95 GHz though). Nice cruncher on a budget, cost 375 USD for the whole system. Eats a bit of juice though ;)

On the subject of patching, you may find this file useful.

This message and the next few have further information on how to use it.

Note: your mileage may vary. Make a copy of files before you do anything. PROCEED AT YOUR OWN RISK! You have been warned.

HTH,
Simon.

@Simon-

Thanks for the help Simon. I believe I have successfully patched my app (after a few bumble-stumbles)

Really looking forward to the GA release of the new science app.

Crunch on!

I'm a NEWBIE to all this "stuff" but I find it all so interesting, so don't beat me up :)

I'm going to ask a "if" question, here it goes: "IF" you were to build a computer for this fun processing of information "stuff" and you could build it they way you wanted to, would you go for more processer speed or more L2 or........?

"If" you don't mind emailing me in addidtion to your post I would appreciate it, I'm new to this as my points indicate and I'm also thinking about building my own machine which I would like to use for these projects as well. danmartinaz@aol.com

Sorry for any mis-spellings.

I hope you're still around, you can click on edit this post (next to your last post)and change your email addy to something not easily scraped by bots. Something like geeimhappy (AT) hot mail DOT com, or geeimhappy athotmail dotcom, or geeimhappy (at) hotmail dot com. Anything but the whole addy. That said, both are important get the fastest for the cash with the highest L2. If the app can fit in L2 then it doesn't have to go out to the slow ram chips (atleast not most of it). Tell us how much you think you can afford. If you can reuse the existing case, what size case, if you wanna reuse the PSU, what wattage, can you reuse the cd drive? Etc. someone might spec it out for you.

Anyone have a RAC for stock e4300? (@1.8ghz).

I just got one, wondering where it's going to go. Using the KWSN linux app, 1.3 (I believe v2 is on the way).

Thanks!

That's really interesting and suggests the extra 2 cores, running at stock, on a C2Q give approximately the same output again

That should follow since BOINC and SETI will use all cores given access to at full clip a quad will use each of the four cores to process a single work unit each so naturally you if you have two cores you have two WU's processing at the same time if you have 4 then you have 4 WU's and so on. If you remember that old CG machine with 127 cores or somthing crazy like that...it pulled alot of RAC but it was a dog per work unit. Took it something like 37 hours per work unit so it really wasn't faster then a 3GHZ C2D

---

FWIW, there's an SG machine back in the RAC top twenty again. It's probably a good thing it doesn't have contemporary PC core speeds (at least from a SAH crunching POV), otherwise with 127 or more cores it would spend most its time twiddling its thumbs waiting for a new quota day to start. :-)

Thinking about it, at this rate it won't be too much longer before quota exhaustion becomes the limiting RAC factor on PC's either. ;-)

Yeah, I've got a feeling Seti may have to raise the limit some as most of the C2D and C2Q cpus can be overclocked to in excess of 3GHz, I just have to replace a NB heatsink just to get the 5th PC working, That is If the NB chip isn't damaged.
