Wrong Ram Working?

Ok so I was surfing and doing comparisons and happened across this,33921 notice the memory type for the i7 920 - DDR3 800/1066

Now I have this RAM - OCZ Platinum 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory Model OCZ3P1600LV6GK

in this Mobo - EVGA E758-A1 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58 ATX Intel Motherboard

My question is, did I screw up? The i7 supports memory types DDR3 -800/1066. The Mobo says 1333/1600.

Who's right? The machine works but I don't think I've ever checked to see what the Ram is running at. I suppose CPU-z would help. Why does it work if they're diff specs? Automatic underclocking?

Building a new machine if the Rams wrong I'll fix it.

^ That's wrong.

Your motherboard will run with the DDR3 1600 just fine. That RAM kit was designed for LGA 1366 specifically.

Run CPU-Z and it should show up as running at 800Mhz. It's DDR ( double data rate ) so showing as 800Mhz is correct. It will show as 667 if it's running at DDR3 1333 speeds.

So CPU-Z at 800Mhz and 7-7-7-24 2T.

OK thanks,
I was afraid I had overpaid for Ram that was super overkill. I feel better now.
Thx again to both of you.
