Dual slot 1 P2&P3 at same time?

[michealb]

I've lived with my p2-350 for a while now,and it seems to to do just about everything I need, games, online, programming,etc.. Now I want to upgrade my cpu after hitting a simulation that hits the cpu cycles hard, now this simulation can take advantage of multiple processors, but I dont want to get another p2, heck I can't even find a processor slower than 600mhz. What I'm wondering is it possible to get a dual socket 1 and put my p2-350 along with a P3(maybe 600+mhz) in it, and if so would it be worth the extra bucks? or would the second processor actually slow it down making a smarter choice just to go with 1 p3 processor?

Make sure ur OS supports dual proc...

No go! You can't mix CPU's, you will need to use identical processors to use dual CPU's or quad, or 8 CPU's.

I use a Dual Pentium3 733Mhz, and haven't EVEN though about upgrading CPU's shortly. I'd have to buy 2 NEW CPU's!

That's the part that sucks about multi-processor systems. Upgrade time becomes a VERY EXPENSIVE NIGHTMARE!

And.... Since your simulation program that you want to benfit from dual processing DOES support SMP. NOOOOOOOOO! A single processor system will not perform faster than a single processor system. Unless that simulation program you have was written wrong, which would be doubtful.

No you will not with a single processor system, if the software supports SMP. This is something that I wrote in another topic, but perhaps will help you:

I have a Dual Pentium III 733Mhz , 768MB RAM, SCSI Ultra160 10,000RPM, and I will tell you right that I really LOVE it! Once you start using a Dual Processor system, you will never be able to go back to a single processor system! As for Dual Celeron at 300Mhz VS. Pentium 3 600Mhz, The Celeron will be able to work at a MUCH more efficient speeds. You will be able to do numerous tasks at one time without the screen freezing up on you while it is processing the first task. As for RAW Power, Pentium 3 will be more powerful, only because not all programs support SMP, and the cache memory speed ratio on coppermine is 1:1 not 1:2.
But let's say that you were to run a SINGLE application that supported SMP such as Photoshop, 3-D Max, etc, The Dual Celeron 300Mhz will be FASTER than the Pentium III 600Mhz. SO it depends on the support of SMP on the app that you want the benfits of SMP.

In my case, while an image is being scanned at a high resolution at about 1440DPI which would take a good 3 minutes or so, I would just go about doing my other things in photoshop and Corel Draw without any lags in speed and don't have to wait around for the scanning to finish. Something that would be impossible in a single processor system that that has a 1Ghz CPU. You will also begin to see many software companies making software that will support SMP (Symmetric-Multi-Processing) for NON-GRAPHIC applications such as games, Quake 3 Arena already supports SMP.

The Best thing about Dual Processing is that you can do multi-tasking without waiting around for the earlier tasks to finish.

Yes, I did do some research and found out win98 doesn't support multiple processors, nor does the upcoming winME either apparently. But Win2k does so that's not a problem. But also (sadly) found out you can't mix & match processors. I mean used to be the same with memory, but then you could with some boards.. thought maybe someone made a board to have multiple speed CPUs on it, but alas no.

Do realize also that 1 cpu would not be the same as 2 for my program, but now I'm wondering if I can get the same speed out of 1 p3 vs 2 p2-350s (or low end p3s) for the same price that I'd have to pay, since the mobo will be ~$200, would I really save any money/speed on the 2 cpu setup. Since 1 P3-800 probably can do the same load as 2 P3-450s and end up be cheaper in the longrun.
