G.Skill RAM - incorrect CAS timings?

Hello,

I've just installed 12GB of G.Skill RAM: http://www.gskill.com/products.php?index=265

It should be running at 9-9-9-24 but is currently showing in BIOS/Cpu-Z as 11-11-11-28.

I'm using an Intel X58 motherboard which should support the ram and timings.

I've got lvl1 overclock and turbo enabled in the BIOS so I'm wondering if those settings mean the ram has to run at different timings?

I've checked the RAM settings and I can manually update the timings to 9-9-9-24 but then I reached settings which I have no clue about such as tRRD, tRTP, tWR and one other I can't recall. That's not to mention what voltage I should change it to.

My motherboard and ram both support XMP profiling so I turned that on but it made my cpu temps increase and the fan was always on so I turned it off - this is what lead me to believe it might be my lvl1 oc and turbo-enabling which is conflicting?

What speed is the RAM supposed to run at when timed a 9-9-9-24? What speed is it running at?

Can't get 9-9-9-24 to work without the odd BSOD but 10-10-10-28 is solid as a rock in memtest+, furmark, heaven benchmark and 2hrs of prime95 blend test.

I suspect the instability in 9-9-9-24 is a voltage issue - it's stable if I remove the overclocking on my cpu but the loss of cpu oc'ing is greater than the difference between cl9 and cl10 so I'm happy to leave as is.

You need to go in bios. Set VOLTS, SPEED, AND TIMINGS MANUALLY. Your not going to get 9-9-9-24 if you got the wrong voltage set. If your trying to run 1.65v memory at 1.5v, it's not going to run at the rated cas speed of 9, it's going to drop to 10 or 11.

the timings are so unimportant. you will never notice that its one setting or another. if your really bored keep screwing with it. but its really not worth the effort.
best case scenario you get it set just right and then you can say "WOO HOO 1 more fps"

No, no, no.

Very important. If your running the wrong timings or wrong voltage, it will not be stable. I don't know why some people even comment.

Like I said, almost all boards default to 1333 with the wrong timings.

The ram is marked as 1.5v memory......

If the memory won't run it's rated timings at the rated speed and voltage. I would return it.

Is 9-9-9-24 faster than 11-11-11-28?

I assumed lower number was better?

Yes the lower the better.

I have the same RAM, but only 8GB and mine was running at 11-11-11-27-1N. Once I enabled XMP (Intel Extreme Memory Profile) it changed the settings to 9-9-9-24-2N and the system seems faster and is stable. Probably a placebo effect on the speed but you might as well use what you paid for. Hope this helps.

P.S. Im running a GA-Z68X-UD3H-B3 motherboard
