Update: Setting HT Link Frequency to 2400MHz seems to have solved the freezing issue. Thanks for the recommendation.

On the memory timings issue, here's what I've found with my G.SKILL CL9 1600 memory:
9-9-9-28-37 (the JEDEC 800 MHz spec settings) works more reliably than the 9-9-9-24 spec setting, particularly with overclocking. Note you need to explicitly set that last "37" (Bank Cycle Time, tRC) setting in your bios.
For more relaxed timings in connection with overclocking, I've also found the following to be both reliable and stable:
9-10-9-28-37
10-10-10-30-40
Maybe this will help with any further timing issues.

My current settings are 1333 @ 8-8-8-24 2T 1.5v and have been stable since my last post however
With my last settings 1600 @ 9-9-9-24 2T 1.5-1.55v cpu-nb freq 2400 @ 1.2v HT link freq 2000-2400.
My system was stable for a couple days then froze while browsing the net.
NOTE: My system has never froze while conducting cpu intensive work such as gaming, stability test(prime95) etc.

That's precisely the same problem the 9-9-9-28-37 setting (1600 MHz) solved for me -- 9-9-9-24 was stable for a couple of days then froze while I was browsing the net. 8-8-8-24 also works for 1333 MHz, but I wanted to run at 1600 MHz rather than 1333 MHz; and the 9-9-9-28-37 fixed the issue.
I've used the other, more relaxed settings, for overclocking the memory to timings slightly above 1600 (bus frequency setting of 242 with 16.5 multiplier gets me to 4.0 GHz with NB/CPU 2420 setting, but requires memory setting of approx 1612 MHz; bus setting of 250 with multiplier of 16 gets me to 4.0 GHz with NB/CPU 2500 setting, but requires mem setting of 1633). All three of the settings I gave will work with any of the above, but the relaxed settings work with lower DRAM voltages.
Regards.

Thanks TMan. I've done all of those things. Actually, I'm quite happy with 9-9-9-28-37. The 9-9-9-24 setting actually carries a tRC setting of 40 (XMP-1600), and based on my limited understanding of the working effect of memory timings, I think the 9-9-9-28-37 is just a little faster (the tRC setting is an overall time performance limiting factor as I understand it). Even so the 9-9-9-28-37 timings have been rock solid stable (knock on wood).

Should common rate be 2T or 1T with these settings?
