Default ECC memory...decrease performance by 2%...

I believe on Crucial's website, they stated that putting an ECC memory into a consumer desktop can decrease the computer's performance up to 2%.

I have a few questions if someone doesn't mind answering.

1. I most likely have non-parity memory right now. (2) 128MB SDRAM PC100 sticks are in my computer. Can I take out the 2 sticks and add in just a single 512MB unbuffered ECC stick?

2. Is Crucial saying there is a 2% decrease with the same amount of memory? Or does it apply to any amount? example: 512MB ECC vs. 512MB non-parity.

or 512MB ECC vs. xxxMB non-parity

3. Adding the 512MB memory will increase the memory capacity by 256MB (should improve performance), but it will be the ECC memory (should decrease performance), so in the end, do i lose performance, or gain?

4. Unbuffered vs. Register. How do know which one my motherboard will take? I'm not even sure which one I have right now. Since I have an el cheapo 2yrs old Emachine, i'm guessing it has the registered memory? Who knows...


Only reason why I'm considering the ECC is because my friend is selling me his 512MB stick very cheap. Otherwise I wouldn't get any memory because for the price he is selling me his stick, i can by a 128MB stick, but my computer only has 2 slots and they are both being used up

sorry for making this thread a bit long
