Overclocking my DDR3 1333 memory

I overcloked my i7 on 3.8 ghZ with memory down-clock on 1145 mhZ. with 1.5 V. My question is can I clock the memory on 1527 mhZ,with 1.5 V(Standard JEDEC), without frying the memory or the DIMM slots on the mobo.

My spec are:

Core i7 920

DDR3 Kingmax 6 GB 1333 mhZ native
 
As long as you don't increase the voltage, you won't fry the RAM or the slots. If you try to take the RAM freq that high, three things could happen:
-- the computer won't POST, you'll get BIOS code regarding memory,
-- the computer will POST, but you'll get BSOD at boot to OS, or
-- the computer will POST and then Boot into OS.
I'm betting on the first because that is a high OC on the RAM.

I keep an excel log of my OCing attempts with the settings I tried, whether or not it POSTed, and if so, whether or not it passed memtest86+, and if so, whether or not it booted into the OS. It keeps me from wasting time on settings I tried, but didn't work.

Thanks, at least now I now that is safe to try. Today I am going to try to increase just a frequency, and I am going to inform you if the operation memory was successful :D

OMG, I just finished memtest without any errors. I overclocked the ram on 1524 mhZ with 1.5 V standard JEDEC. The PC runs fine, games are awesome, on every benchmarks that I tested I have significantly increase of memory performance. So far everything is O.K, so may next question would be can I leave this setting for 24/7 use?.

P.S Memory timings are 9-9-9-24 AUTO settings. Can I use for example 8-8-8-20? If not should I input 9-9-9-24 manual in the DRAM timings?

What is the timing normally?? 7-7-7-24??? That is what is sounds like here
Now if you are just under 1333 or at 1333 at the SPD/ Memory Frequency you are fine.

I have Kingmax 1333 Mhz. I overclock the RAM on 1524 Mhz with 9-9-9-24 timings(these timings were set by their defaults). So my question is, is it safe to try to tighten the memory timings, let say 8-8-8-24?.

Well what i would do is turn down the Mhz and make sure are at 1333 or under.
But if you overclock your CPU by 18X multiplier and Bus speed is at 215 - 222, you
you should try to set the SPD around 1333 or under. But even at 1333 it would be at 9-9-9-24
switch is fine because I also have the same

Wait,I did not understand you say to down-clock the frequency of the memory?. But all time I was trying to overclock the memory. The point was to do a little boost in memory performance(which I succeed with overclock with 1.5 V). So can you explain me why I should decrease the frequency?

Then you have it where you want it, then run a memtest86 to see if it stable or not.

I have my own way in overclocking my memory and you have your own way but
If I were you, I would want to run a memtest86 to see if the memory is stable in that overclock settings.
If not then you need to just down it a little to about 1360 1400

Yes time to get your hand and your brain dirty. You want to start off at anything high like 1360 and then 1400 before going to 1560
