RE: I'm a (once) proud

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.

However, I'm positive that I still have the original PIII 500Mhz Slot 1 that it originally came with. If Tullio wants it, I'll be glad to drop it in a post box and let it take a slow boat to Italy! I'll be very jealous, of course, since I've not had a chance to return there myself since mid-2000. :(

What a great thought and what a kind gesture!! Not only would Tullio get a nice frequency increase but he would also get the benefit of SSE. The only problem he might have would be if the heatsink is not of the appropriate size and type. It's actually relatively easy to swap heatsinks in a lot of cases though.

Cheers,
Gary.

Thank you very much, but I am not a hardware guru. I prefer downloading some software source program and compile it on my Linux box. My PII is good enough to do such things and watch NASA streaming TV. Speaking of nostalgia, once I crossed Kansas on a Greyhound bus going from St.Louis, where I was a student, to Los Angeles, where I have some relatives, and back. It took me 60 hours to go there on old Route 66 and another 60 to come back. Happy days!

Yup, speed is not everything :-). But be prepared that your P II will have difficulties meeting the deadline for the monster WUs that are distributed right now :-(.

I might have to suspend SETI as a last ditch effort. That is not a problem. The real problem is when QMC sends me a monster WU along an Einstein WU. Then I have to use a slalom technique between the projects. Cheers.

Tullio,could you please tell me what frequency your P II is?I have one sitting idly,but not sure about running EAH.

And then I have whole range of Pentiums I and 486,but I doubt they would make it worth... :-(

And inactive AMD K6.Could it be of any use?


My PII (Deschutes) clocks at 400 MHz. 486, Pentium I and K6 are useless. I can meet deadlines of both Einstein and SETI, but a QMC WU is very long to crunch. I get 2.6 credits/hour on Einstein, 2.2 on SETI but only 1.9 on QMC.
Tullio

Thanks Tullio for info.
That 486 and such are useless I guessed and they would not survive such workload.
However how close to deadline does your computer get?

Excuse me, but K6's are not useless and are fully capable of running EAH. I have two K6/300's which have never missed a deadline here until S5R2, and I'm virtually certain that a late model PI-MMX can cut it as well, due to the generally better FPU performance of the Intel's back in those days.

The only problem for them is the deadline 'tightness factor' currently. If EAH had variable deadlines (like SAH) to maintain the tightness factor constant over the template frequency range they would run the 630's just easily as a Core 2 Quad can.

In that message you referenced, Tullio said that his machine gets 2.6 credits per hour on Einstein. So as a rough guess, a 650 credit monster WU is going to take around 250 hours or just short of 11 days at 24/7 operation. So a 14 day deadline result is still achievable, provided the Gods are smiling :).

Cheers,
Gary.

I would say about 50% of the allotted time so far. But I still have to receive a monster WU.

Sounds about right. Anyway keep those Old Timers chugging away. For what most people in the world use a PC for they are more than adequate. ;-)

PII's and PIII's really were remarkable in their prime. And Intel knew it, as evidenced by how much they hosed you for the privilege of owning the latest version of them back in the day. :-)

Come to think of it, they still do! :-D

Just to be fair, when AMD managed to catch Intel napping they didn't have any problem playing the same game either. Nothing good or bad about that, it's just business!

Got another 424.70 credits

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.
