Does an FC-PGA ----> Socket 1 adapter hurt performance?

[Sparky Anderson]

Currently I have a P3 450 @ 558 running in an Abit BE6 board. I'm looking to put in a P3 700E into it, and I read that the FC-PGA would be the way to go over the slot 1. I'm guessing if I want to upgrade the motherboard later on or whatnot the FC-PGA chip will still be usable...but what I'm wondering is if this adapter will hurt the performance at all?

Tests run a while ago when the FC-PGA/PPGA processors came out showed that there was no performance difference between Slot processors and socket processors running through a slotket.

Thank you.

Got any links?

Also...

I am just reading up on the Abit SlotKet (http://www.abit.com.tw/english/product/slotket.htm) and it says:



<< CPU FSB adjustable (66/100/133) via Jumper >>



Does this mean I can't use any other FSB speeds other than those 3? Meaning I couldn't use a 124 MHz bus or 112 MHz or anything inbetween.

Thanks for the help.

The way a CPU/MB works is that CPU sends out a signal saying

For a P3 550
I'm A P3
Default FSB = 100
Default Multiplier = 5.5

Your motherboard reads these signal and uses it.

For a slocket its the same, you're setting the default FSB thats sending to the motherboard at 66/100/133
Onces the signal is sent, the motherboard can accept the default or when you raise it manually. So you can change it as long as your board can do it.

Ohhh...ok.

So that is just the FSB for the CPU (ie. Celerons at 66, P3E at 100 and P3EB at 133). Then I set my FSB in the bios and can still run at whatever speed i like.

Search for other threads on this - I know they're there.

At least get a name brand slocket, maybe the same brand as your mobo, which is what Intel suggests.
