Z77 and 2600k features.
 
Hey HWC,

I'm moving to a z77 maximus 5 extreme in my upcoming revision of my rig and taking advantage of trim passed in raid 0 and having alot of fun with asus' flagship board. But I'm still unsure about what processor to use. What features exactly would I be missing out on by stick with a 2nd gen i7 over selling it and going with a 3rd gen i7?

From my understanding I don't get PCI-E 3.0 which doesn't impact my build and I'm stuck with my disappointing 2nd gen memory controller.

Importantly I want to verify that the trim in raid will work using a 2nd generation i7 as long as the chipset is z77 and I have the latest chipset drivers installed on the OS.

My 2600k is near and dear to me as I have benched it at 5.3ghz(5c coolant) and I consider it a 'golden' chip. The downside is the memory controller really doesn't like going above 1600 c9.

Opinions?

for the ram i doubt its the mem controler i got a first gen i5 750 and my mem clock at 1866 mhz its probaly your ram o and my ram is rated at 1333mhz

gen 2 i7 memory controller's are 1333 native and known not to OC well. I have a set of dominators that can run 2133 11-11-11(also on a 1st gen i7 but 1366) but my i7 2600k can't hold them stable above 1600. I've tested this chip on a few different boards with a few different sets of ram.

well that sucks did not know that

most of the gen 2s can do 2000mhz stable depending on timings
your right the 3rd gens mem controllers are much much better tho capable of 2800+ with the right memory.

no pcie 3.0 is also correct

and about a 10-15% performance per clock difference.

thats really all there is.
