CAS & MHz advice

[Macphisto]

which of these 3 set-ups is the better? I have no idea when it comes to CAS and MHz of RAM

It will bet set up with i7 on a Z68 board

8GB (2x4GB) DDR3 1600MHz CAS 8-8-8-24
8GB (2x4GB) DDR3 1866MHz CAS 9-10-9-27
8GB (4x2GB) DDR3 2000MHz CAS 10-10-10-27

Also is 1600MHz CAS 8-8-8-24 worth an extra £20 compared to 1600MHz CAS 9-9-9-24. will i really see much of a diff?

Personally, if they're branded memory (Corsair, Kingston, Crucial, etc...) I would get the 8GB (2x4GB) DDR3 1600MHz CAS 9-9-9-24.

And no the 8-8-8-24 is not worth the extra £20 over the slightly slower timings as you wont notice any real time gain.

Edit: For example this Kingston set - link - on a this week special is great value and has a proven track record of running sub 1.58V (crucial when clocking SB) and will usually run at 1.5V.

Or these with low profile heat spreaders for the best compatability will large CPU coolers:

Hehe, the offer probably ended 10 minutes after i hit submit on my post - forgot it was Wednesday.

All of the sticks that Surveyor has linked to above are great value - i personally favour the Corsair.
