Well, I finally got around to doing it. I swapped out the dual 800MHz P3s and replaced them with my old 700MHz P3s equipped with new well lapped 17cfm dual fan heatsinks. The motherboard (PIIIDM3) is jumpered to 133MHz FSB. The result? The 700MHz processors (SL3XM) are running at 933MHz and approx. 37.78ºc under heavy load (working on two results plus several other programs running).

Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.

I have Dual P3 and have found seti runs faster by about 10% faster if one cpu is running another project, Einstein or CPDN tried so far.

I have Dual P3 and have found seti runs faster by about 10% faster if one cpu is running another project, Einstein or CPDN tried so far.

On the 800s seti averaged about 12.5% faster with one instance running vs two running.

The 700s are doing very well as 933s, running @ 1.59v and 98-100ºF under heavy load. Time to keep an eye out for an ami megadual and a cheap pair of 750s to run at 1G (for the other tower case I have sitting here).

This is true of most machines, they share ram and therefore are not "true" dual crunchers. It more than makes it up though in that you are losing about 12% time but actually doing 2 units in that 112% time, instead of 1 unit in 100% of the time.
The same is true for my dual core P4D with Ht on each core, the machine thinks it has 4 cpus and does 4 units in about 90 minutes.

A recent buy on my workplace has opened my eyes, when it comes to crunching SETI WU's. We bought a Dell Precision 380 with Intel D (830, 3 GHz) Dual Core with 2 GB RAM, and this does 2 WU's in 30 minutes. That's about 12 times faster than my (slightly) overclocked AMD 2500+!

I'm all for OC-ing, but sometimes it can be faster to buy a new machine - and then OC that one also, of course. :) Old machines use just as much power as new ones. If you have a farm with 4 or five old machines, you can spare yourself and the environment a lot of power consumption by replacing them with one new supercruncher. :)

That is way too hot. You should change your CPU cooling solution. Here are a few alternatives:

Zalman Reserator 1 Plus
Thermaltake Big Typhoon
Thermaltake Silent Water

Yeah, 84c is smoking hot...184 F...you know the chip itself is hotter! She's gonna fry!

Mine runs about 47C-49C (116-120F)

My heatsink has a small length of tube attached to it which runs out of a hole in the wall to the outside, thus sucking in cold air (works best in winter) and blowing it over the CPUs, another fan then expels the warm air out of the front of the case and heats the room quite nicely :)
Result: 2 3Ghz CPUs with HT, running 24 hours a day at 100%, currently at 34C, this system works a treat.
It varies obviously depending on the weather outside and also whether its night or day but rarely goes above 40C this time of year, in Summer it will most likely get hotter but i'll worry about that then <grin>.

BTW, the bit most likely to burn out are the fans, they're running at 18v to suck in more air, still nice and quiet though.

Life on earth is the global equivalent of not storing things in the fridge.

So, can anyone give me any ideas for overclocking? Anything I can do while sitting right here? I've always been interested, and this thing is going on three years old , so why not try it?

I've got: a Sony VAIO, 2.65 gigahertz Intel Pentium 4, 8 kilobyte primary memory cache, w/512 kilobyte secondary memory cache. MoBo: ASUSTeK Computer INC. P4S533VX REV 1.xx, Bus Clock: 133 megahertz, BIOS: Award Software, Inc. ACPI BIOS Revision 1001 08/20/2002. It's got 1.5G of Crucial memory.

Any good sites that are more computer specific? So often it seems like a dice roll, and I don't want to cook this thing. I have Everest, so I can monitor everything.

Thanks for any thoughts, guys. 8^]

Overheating will be the main problem in a laptop.

Try Overclockers.com, they've got the right url for this topic, not a bad place to start.

Thought the Sony VAIO was a type of laptop, my mistake.

Don't know any How To sites, try googling it, there will be plenty out there.

Try these: http://www.hardforum.com/

One note...I DO NOT OVERCLOCK! So I have no PERSONAL experience with ANY of these techniques. One thing I HAVE learned though is DO IT SLOWLY, go a little at a time, do some very thorough checking and then do a little more.

Welp, too bad it isn't freeware....it does have a very very annoying time limited (with the useful features blocked) version.

Yeah..it is too hot. My Inteld D runs at abt 57-61 Clesius...before my liquid cooler ($250) was put in. Now my 3.2 gig dual core is running at abt37 Celsius, average. I am using an "exotic" fluid instaed of water. In fact, it is the automotive cooling system performance improver. MY SETI WU's are taking slightly longer, but do have other bkgnd stuff slowing things down some.

ADLKIRK, I'm very interested in your liquid cooling solution and what the "exotic" fluid is. I'd be very happy if you could provide link(s) to some more information. Thanks! :)

ADLKIRK, I'm very interested in your liquid cooling solution and what the "exotic" fluid is. I'd be very happy if you could provide link(s) to some more information. Thanks! :)

The "exotic" fluid can be found at automotive stores under various brand names. When added to your car's coolant, it's touted to run the car 10-20 degrees F cooler. I have run this 100% pure in my liquid CPU cooler. I'll get you the brand name in a day or so. Once it went in, the can went out. As it wasn't real important to remember, I didn't ;)

I'll provide the cooler name brand too in the same post.
