Memory Upgrade

[pavloschristo]

Hi. I'm looking to upgrade the memory in my system
My Current system is:
Intel Core i7 930 @ 2.80 GHz
Asus Rampage II GENE Motherboard
AMD ATI Radeon HD 5770 XXX (875 MHz, 1028 MB @ 1300 Mhz)
OCZ 3x2GB DDR3 Triple Channel @ 534 MHz (sorry I can't be more precise)
OCZ Mod X Stream-Pro 600W PSU
Coolmaster CPU watercooling block (forgotton the model)
Intel 330 120 GB SSD
Windows 7 Home Premium 64-Bit

If I buy another set, say the 'Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 1600MHz Triple Channel (CMX6GX3M3A1600C9)' can I use it along side my current memory or should I replace it instead? Will there difference in speed effect each other?

Thanks

You would need to replace the old set, as your new one would be almost twice as fast.

ok. Thanks. Thats what I was thinking

No problem!

Don't want old RAM slowing you down

It's possible he's not running the memory at the right settings though, and that's why it's showing up as 1066.

Could you download CPU-Z and take a screenshot of the SPD and Memory tabs?
