Running RAM CL 10-30's @ CL 9-24's ok? Will it cause any problems, or shorten lifespan...

[illumind]

I just installed the below into my MB and it's running at CL 9.9.9.24 1333MHz, which is the same speed and timing my previous RAM ran at. Is this ok, or will it shorten the life of the RAM/mobo as a result of not running at it's "natural" slower timing and faster speed? It should be running at CL 10/30, just to save opening the below link.

I did some googling, but all I found were threads on mixing the two speeds/latency types together, which I'm not trying to do. I haven't enabled XMP, but when I've tried with previous RAM it doesn't appear to have any effect. I'm guessing the motherboard is set a certain way and unless I reset it or manually change timings it just holds to 1333MHz and CL9/24, regardless of RAM type.

Any info or answers would be greatly appreciated!

Running ram at tighter timings than spec will not shorten the lifespan. Tighter timings may cause system instability but if this happens, simply change to spec. Is the Gskill the only ram in your system or do you have it running with a different brand?

The G.Skill 16GB is all I have in currently. Was previously 8GB (2x4GB) CL9/24's:

What's the wisest (&/or most common) way to run this RAM in my MB (Z68MA-D2H-B3) , considering my board is defaulting to 9/24,1333MHz? What would you do? Or, what would others do... Opinions?... Enabling XMP doesn't do anything, and I'm afraid to play any further with BIOS settings.

some boards do better than others reading XMP profiles. you'll get a slight bump in performance by manually setting the Mhz to 1600 and change the timings to 10-10-10-30-2n.

If the system doesn't boot, clear the cmos and it will put everything back to default.

Yep, understand re speeds and timings, at least on a fundamental level. I just wasn't certain about what it would mean for a system if you ran CL12-12-12 RAM at say CL 9-9-9. I'm wondering at what point this starts to become a problem, if ever, in terms of stressing out any component - assuming it runs stable... From what you've said, as long as it's stable there is no extra wear on anything or shorter lifespan.

My earlier assumption is/was that running RAM at tighter timings might very marginally reduce it's health long term, for want of better words. But apparently this is never the case.

Thank you for explaining, the help is appreciated.
