DDR3-1066 CL7 or DDR3-1333 High Speed

[Jez(UK)]

I'm upgrading my system and need help choosing ram.

It'll be for running 3DS Max, Photoshop, Video Editing and the other usual MS Office, internet, playing music etc.

I've opted for a i7 940 proc, with a Noctua NH-U12P heatsink all put onto a Supermicro X6SAX mobo.

I'm not intending to overclock this machine, but I am confused about the memory that will be best suited for it and my applications.

I'm going to be putting in 12gb of ram.

Crucial do a 6gb memory kit which is non-ecc, ddr3-1066, 1.5v and sells around £80.
They also do a 6gb highspeed ram kit, non-ecc ddr3-1333, 1.65v and sells for £180.

So for an extra £200 I can have the highspeed ram - but what will it give me ?

According to what I have read, the i7 940 processor supports non-ecc ddr3-1066, so what would the point be of getting the highspeed stuff if I'm not going to overclock ??

If I didn't overclock and put the faster ram in, would I notice any difference (the mobo supports upto ddr-1333, the processor doesn't).

Please advise, I'm not an expert in all of this, though I have no problem building systems/installing OS's etc.

Many thanks,

Jez.

i would go for the cheaper option to match your processor speed, the difference you will see is negligable between the speed, obviously you will need a 64 OS to use the ram.

Thanks KingZeddy,

That's what I decided to do end the end - I got the Crucial Ram (12gb) of PC3-8500 for £135 in the end (D A B S was even cheaper than Crucial on this one!)

12gb of ram for £135.........

XP Pro 64bit here I come !

FYI, your processor will support 1333 and faster memory, depending on the BIOS options. The memory dividers are unlocked on retail Core i7 CPUs.
