can my G Skill 1600 mhz 8-8-8-24 be stable at 7-7-7-24 or lower on a i5 3570k on a asrock z77 extreme 6 motherboard?
 
Solution
1) Probably yes, but May need to raise Ram voltage to 1.600 V
.. Have G-Skill Ripjaws DDR3-1600 CL7 (4 x 4 in one system and 4 x 2 in a 2nd system. The Ripjaws that are rated at DDR3-1600 CL8 @ 1.500 V are probably the same as My DDR3-1600CL7@1.600 (my Guess)
.. Reason for the CL7->CL8 is probably because they also lowered the Voltage to 1.500 from 1.600. Reason for the voltage drop is that starting with SB (ix-2xxx) Intel moved the memory controller to on-die an the Spec calls for a MAX voltage of 1.575V. NOT I've been runing my ripjaws at DDR3-1600CL7 @ 1.600 eversinse the i5-2500K cam out with NO problm (it does invalidate Intels CPU warrantee - But then OVerclock does that anyway unless you purchace the Intel OC warrantee.

Depends on the sticks. Sometimes they handle it, sometimes they don't. That being said, I suggest trying to set it at 7-7-7-24 and running memtest86+ overnight, to see if it handles it properly.

Memtest basically writes data to the RAM and checks it afterwards: bad ram sticks, or on bad latencies, return incorrect data. If it shows no problem overnight on the test, your sticks are fine on that latency.

EDIT: That being said, people on other forums are recommending 8-8-8-24 1600MHz for that stick in particular.

2) Use Memtest from a BOOTABLE DVD to check memory stability, Then use Prime95 to recheck memory stability when in Windows.
... I find Prime95 does a Better memory check than Memtest86+.
...... One caution, Monitor Temps closely for the First half hour as it does heat up the CPU.

3) That said, Is it really worth it???. The performance gains going from CL8->CL7 can be noted running a Benchmark program: HOWEVER, in real life day-to-day operation you will NOT see a difference in performance - There may be a couple of apps that can take advantage of the decreaed CL ratings but these tend to be expensive programs.
