Celeron 566 help!

I just replaced my trusty Celeron 300A running at 464 with a Celeron 566. I was mainly interested in increasing frame rates in q3. With my 464 I usually got around 83-85 fps on demo001. Now I just tried my 566 (@566) and only got 75-78? I was wondering why this would be, does simply replacing the CPU change anything else? Should it be slower than my 464? Is it b/c it isnt "broken in"? Please help me!
BTW at 850 the 566 is faster than my 300@464, but am still curious as to why 566 is slower than 464 even w/ the new SSE instructions used by q3.

Also, what programs are recommended to "burn-in" my new cpu? I remeber back when i got my 300a it was a program called prime 95, does it still exist, and is it still recommended?

TIA

Are you positive that the only thing changed was the CPU? If so, then the FSB speed may be the culprit, and likely is. When your 300a was running at 464, you were using a 103 Mhz FSB. With the 566 not overclocked, your FSB is only running at 66 Mhz. Even though the CPU increased by ~100 Mhz, the data is traveling from RAM to the CPU at a slower speed, resulting in an overall decrease in speed.

I'd recommend overclocking the 566 if you can. I just today got my 533 Celeron and overclocked it easily to 800. I'm going to try to bump it up some more tonight.
 
BoberFett.....the ONLY thing i chaged was the CPU, i was thinking the same thing but didnt think it would make 10 fps difference when the cpu itself is running at a little over 100 mhz faster. Could the use of a slocket be the culprit here?

My 566 will make it to 850, and will not go to 952 like i had hoped 🙁 Maybe after a proper "burn in" it will make it there. My celeron ran fine at the default voltage at 504 after a proper burn in. Thanks again....
 
The reason that i care is that I was wondering if i got a bum cpu or something was changed. I also want reassurance that i am getting my moneys worth. If it changed something or i got a bum cpu, then i would like to be able to fix it or get it back the way it was. This would obviously make the frame rates higher even yet, so that is why i am worried 🙂.
 
Foomanchu When you changed your cpu you also changed its bus,your memory's bus, and to a much lessor extent your graphics card's bus. You basically slowed down everything you were benchmarking except the mhz of the chip.🙂
 
Yo, Foo.

The strength and weakness of the Cele is its system bus speed. At the stock 66 MHz the Cele is a dog no mother could love !! But you buy them because you really love them and are going to smother them with overclocking love. At 100 MHz (that's 850 CPU clock) they sing, and perform like a P3 Coppermine 600E (which costs twice as much) or an old Athlon or Duron of similar speed. The reason it doesn't do better is that its L2 cache is a limitation. But at the price its great.
