I'm a (once) proud owner of a pair of those rare 600Mhz PIII Katmai's.

Thanks very much for sharing your story. I looked around for 600s when I did my first PII -> PIII upgrade around 18 months ago but couldn't find any. So I settled for 550s and moved on. I was quite impressed with how easy the upgrade was. I didn't even consider the possibility that the VRMs might be different.

Yes, if the BIOS knows the CPU-Type and the revision ob the mainboard is right (VRM-Capacity) its a simple change of the CPU.
The 600s run at 2,05 Corevoltage, 0,05 more than the average Katmai. So to speak its overclocked by default at the factory. But its termal stable, mine never got over 62 Grad Celsius. ;) Very reliable.

I run a PIII-600 on a ASUS 440BX Slot1 Mainboard as a office system under Win2000, its a little overclocked with the FSB at 103 MHz to 618 MHz.
At daytime it runs a java-program and firefox for one of my relatives with Boinc as backgroundtask (service install). Several projects are attached beside Einstein, which runs only occasionally. No trouble with deathlines so far.

On a sidenode: the old 4.17 app needs ~486.500 sec or 135 hours for one WU, 4.24 got it in 380.394 sec or 105,66 hours of the same frequence.

Got another 424.70 credits today using App 4.21. I stopped new work until I loaded the new App 4.27 on a fresh unit, and am now crunching SETI. Should get another 68 credits on SETI within today. Not bad for my PII.

I see that took nearly a week. Wondering what that took in energy consumption versus something a bit more modern day.

Yes, my frequency is low (400 MHz), which means my CPU stays cool. I have only two coolers (fans) in my PC, one for the power supply and one for the CPU. Since energy equals power times time, a more powerful CPU would need more power for itself and for the coolers. Naturally, it would finish its job in a shorter time. So the question is: how many energy units (kWh or joules) does my PC consume to finish a WU compared to, say, a dual or quad CPU ? My power supply only reaches 300 W and must power the CPU, the fans, the Mobo, two hard disks, 4 PCI boards and a DVD. My system is running 24/7 in a room without any air conditioning and now, summer, the temperature in my room is 30 C. Once I had a 10 MHz AT@T UNIX PC and in summer I had to shut it down because its fan would go in turbo mode and make a whirring sound (this due to the closed casing of its desktop architecture). I am using a midtower casing with plenty of air around it.

Ballpark guess, assuming EAH

Ballpark guess, assuming EAH drives the PII close to it max ratings: ~4 KWh, plus whatever else the machine draws for the rest of the subsystems while operating.

I've been watching your Deschutes for awhile, and it really is amazing how well it performs considering it's going on ten years old and only supports MMX. ;-)

Above all, I NEVER had an invalid result in Einstein, SETI and QMC. Its FPU must be very good. This refers also to the Linux libraries and the extended precision of their floating point variablea. I've read, in a CERN seminar on floating point arithmetics, that SPARC and Itanium have the best FPUs. Unfortunately, I cannot afford any of them.

Yep, and the PIII follows right along in the steps of the PII when it comes to excellence. My 550 Katmai is only a year or so newer than your Deschutes, is a PC100 device running on a 440BX MB, and I never hide my machine except to test project website functionality changes, so you can see what it can do.

As was mentioned earlier I'm pretty sure it would be a direct plugin replacement on your machine. I've seen them and the 600 version go for pretty cheap on eBay at times, so it's not like you're at the end of the road for your old timer by any means. :-)

As far as SPARC and Itanium go, yeah they sure ask for the big bucks for them. I often thought 'Unobtanium' was more appropriate for the Intel offering. ;-)

Great, half my question answered. Thank you. So what does mine consume to finish a work unit ... ballpark of course.

You can buy a power meter for

You can buy a power meter for under $30 to measure your consumption directly, but depending on how high end the parts in it were when designed (a state of the art 2000 gfx card will draw much more power than an equivilent 2007 model) and if you have extra drives in, most non gaming consumer PCs will use somewhere between 100 and 250W at full CPU load.

To convert into anual power consumption, you can use the approximation that at $0.10 per kwh, a device on 24/7 will consume $1 of electricity for every watt it draws.

Hmmm..

Apparently AMD is not making it as easy to get to the older stuff datasheets as Intel is. That's something new (and unwanted). :-(

However, using the same ballpark estimating with the best third party info I found on your proposed result: ~1KWh.

However, keep in mind that Intel and AMD rate total dissipation differently, so without seeing the actual datasheet this should be taken as even more crude than for the PII (and that was pretty crude). ;-)

However as Dan pointed out, a 'Kill-a-Watt' is pretty cheap and removes all doubt about power consumption under actual operating conditions real time for the whole box.

Although I question the comment about graphics card power consumption. Back in 2000 you could get a mainstream card that didn't even need a fan to operate safely. Nowadays they almost need their own separate power supply and some draw more than the main CPU. :-)

I forgot my graphics card on the AGP slot. It's a Matrox 200, 8 MB RAM, no fan. But I rarely use it except when my grandchild comes and wants to fly a 737 in the Microsoft Flight Simulator.
