Which 2x4 gigabyte with Asus P7P55D Pro?

Hello, everyone,

My son wants to upgrade the memory in his system to 2x4 gigabytes. It's an i7-850 in this motherboard:Newegg.com - ASUS P7P55D PRO LGA 1156 Intel P55 ATX Intel Motherboard

The much-recommended Corsair (Newegg.com - CORSAIR XMS3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model CMX8GX3M2A1333C9) is out of stock everywhere.

If he can't wait, is this a reasonable substitute?
Newegg.com - CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9

What else would you recommend?

Thanks!

Dave

Might as well get the Crucial stuff - it's no cheaper at Newegg.

Dave,
That board will natively clock 1600 RAM.

Why not get this?

1.5 volt ram will be more stable and you have to overclock the CPU to get ram to run at 1600.

But cant you run the 1600 RAM at 1333, which leaves the FSB (or whatever its called now) at the same speed therefore leaving the CPU at its factory speed?

Looks like Frys has the one I need:

DDR3 8GB (2x4GB) 1333MHz with XMS Heat Spreader, CORSAIR CMX8GX3M2A1333C9 FRYS.com*|*CORSAIR

I'll have to pay $130 plus tax, then get back a $40 rebate, but I think I can pick it up tomorrow.

Thanks for all the help, gentlemen.

Yes you can - but why unless you plan on overclocking?

Because he is looking for something similar because what he wants is out of stock. Yes, I saw the Crucial recommendation.

yes you can manually set the ram to 1600, but i ran into some stability issues w/o OCing the rest of the system(i run the same mobo), and you wont see any difference in real world scenarios, only benchmarks with a memory suite.
