| [OT] Question Intel 3.2 775 v Intel 3.2 478
I have an Intel socket 775 3.2 ghz HT processor with 1 meg L2 cache. I know it's a P4-540 processor.
I also have an Intel socket 478 3.2 HT ghz processor with 1 meg L2. Is this the 3.2E ?
Is there any difference between the two other than the socket type?

There is a big difference in the achitecture in how it connects to the north and south bridges on the motherboard to transfer data. If you mean extreme edition when you say 3.2E I dont think so.

Well, I already have what I think is a 3.2E-478, and I have a 540 that is right now waiting on Berkeley to download it's first work units. Literally...
I was just trying to figure out what difference (if any) I might see in terms of crunching power.
My 3.2E cranks out 46 results a day (two results every 64 minutes), and I was wondering if this new 540 would do the same. I guess time will tell.

It looks like different chip sets and data channels. Also the memory type. The core technology is not similar but I only linked the basic description selection. Intel has a more detailed section on each CPU. Check it out.
I am sure there is more than the socket that is different.

Depending on the type and speed of the HDD you use all things being equal the 775 should give better performance due to better data transfer speeds however this may be hard to measure depending on the software being used as some programs rely on stored data more than accessible memory data although the 775 does transfer that data more efficiently with less bottlenecking as well. The type and speed of memory used with both CPU's will be the limiting factor there.

The machine is a dedicated cruncher, so I don't think the HD will be used much except to handle a tiny state write every 60 seconds.
The first four results came in at an average of 50 minutes.
This 540-775 board uses DDR2-667 memory, the 3.2E-478 uses DDR-400. Both systems have a 256 meg stick of crucial memory, both are running Linux and Naparst's setiathome_SSE3-naparst-r3.4 optimized client. |

| Here's an interesting observation.
I had my 630 in an Asus P5rd1-vm motherboard, which uses an ATI chipset and DDR, and I had pc3200 in it. It was averaging 2 wus in a little over an hour. I just switched the motherboard to an Asus P5ld2-vm with the intel 945 chipset and is using DDR2-4300. The times dropped to an average of around 39 minutes/wu.
Both were overclocked to 220 FSB. Unfortunatley, I'm not sure whether the memory, the motherboard, or a combination is responseible for the drop in times, but I do know I'm not going with anything other than an intel chipset that supports DDR2 memory from here on out  .

Running linux with an intel processor I have had better luck with these optimized clients:
»naparst.name/seti.htm
My p4 530 has 512mb ddr 400 and a RAC of 1372. All it does is crunch, I have it boot to a cmd prompt and boinc runs as a service.

Sorry, I am also using Naparst's Seti client. Are you running stock or overclocking? Both systems are Fedora Core4, updated to the latest smp kernel.

OK, the 540 has 38 results so far, at two results completed every 51 minutes.

Your 530 and my 540 are both clocking in at the same rate.
Do you by chance have a log file from that machine?
if so, with some effort you can extract the actual wall clock times via grep, awk and sed, copy/paste into excel and come up with an average per result. The most I can figure out how to copy/paste with that method is 499 results.

from the linux command line, in the boinc directory
./boinc >> boinc.log 2>> error.log &
This will start boinc as a background process, and direct the stdout (what would normally display on the console) to boinc.log, and any errors to error.log

Further on this Intel Model 540 775 processor.
In the first 24 hours, the blade completed 53 results. Trux has raised the claimed credit to 20, and it's still rising. Past experience tells me 48 hours to achieve normalized 32 claimed credits.
The CPU was installed in an ABITT AW-8 motherboard with a 256 meg stick of DD2-667.
I just re-installed the CPU in an ASROCK 775MV100 motherboard with a 256 meg stick of DDR-400 (PC3200).
*gotta love Linux for not really caring that I just changed a motherboard - It just booted up and continued crunching right where it left off.

I just noticed i had not set up for it to run as a service on that machine. Must be slipping! I restarted boinc and have it logging now. Will try to get the info to you tomorrow. Working on setting up the new motherboard for my pent d 805 right now
