PC tech question

I have just repaired an old Intel P4 1.8Ghz Pentium chip system which I'm trying to get it working smoothly.
The bios settings are
User defined
CPU Internal Freq 258Mhz
External clock 100Mhz/ 33.3Mhz
Multiplier factor x8
CPU clock 2/3 (66.6Mhz)
RDRAM bus Frequency 6x
Flash bios page on boot up
Direct rambus/Host freq 615/129Mhz
It works but seems slow considering its a Intel P4 1.8Ghz chip and it says it'll take 40 hours to complete a Einstein project.
I have a Intel P3 800Mhz chip which does the same project in 3 hours 30mins, Any advise on better settings please.
cheers

Only a guess I'm afraid.
boincmgr usually over estimates the 1st WU and gets more accurate the more WUs you process.
What does a quick calc on % done and time taken give you?
And, are you running the same science app on both of the above machines? Make sure your not comparing it to a machine thats running an opti app when the 1.8 is using a standard app.
Other than that......

It is it first time at crunching and using the latest boinc software 5.4.11 instead of my other machines using 5.4.9
Rough calc
2 hours to complete 9% thats slow.... John

Einstein@Home has some massive WU's at the moment, just leave BOINC to it will re-work the estimates over time

20 hours sounds about right for the newer WU's - it'll drop further on your spec, my guess around 15 hours. My 500Mhz laptop does them in around 20 hours so yours should be around two thirds quicker.

I'm not so sure the bios settings are correct for that type of chip.
Just seems weird numbers, tried setting at
100 x 18 and it doesn't like it.
I'll try the intel site and see if I can get the correct settings.
As for the WU's being much larger, thats ok then..
Cheers guys

Hi "Havoc"
Irrespective of the actual settings, why not use the BIOS to reload the default settings?
Then you can see what's what and what should be correct.
If that doesn't work, remove the back-up battery (usually a small watch battery) and leave it for 24 hours.
Soon be sorted.
regards,
Tim
