usually 1.65v is the universal voltage limit for ram. as for the timings I am not really sure ram can be quite sensitive.

for DDR3 I really wouldn't push it past 1.65volts to be on the safe side_

You can try 8-9-8-24-33-1T
Then try 8-8-8-24-33-1T
Then push it to 7-8-7-24-33-1T
And if it still boots and test fine, try running 7-7-7-24-33-1T

What I am basically suggesting here is that you try to lower the first 3 timings to the lowest number you can acquire without Errors, once you get the lowest possible timing on the first 3 numbers then you can move to trying to lower the 4th timing number [24] and see if you can push it down to [20] or so

This is how I usually overclock my ram_ Otherwise see if you can bump the ram up to 800mhz(Which is 1600mhz DDR3)

Well okay so lets start over haha, First try to run your ram at the highest speed they can run at without errors, for instance from 1333mhz try going to 1600mhz and see if they boot at your current timings_ If they do and have no errors then you can do as I suggest to lower your timings to the lowest possible timing. It can be a long slow enduring process but its well worth it. If you end up not being able to boot, start raising Ram voltage bumping .05 volts at a time(Just keep it under 1.65 and you should be fine)

memtest to test ram and use CPU-Z to check ram current timings and speed_

Google them you should come up with something
http://www.cpuid.com/softwares/cpu-z.html - CPU-Z

http://www.memtest86.com/
Go to the free download page and download an iso image and burn it to a CD then boot from the CD, it will run the program during bootup _its quite easy to use

Typically, RAM doesn't want to go any higher than what it is spec'd for when you buy it. Going by what is in your sig, you have RAM that is guaranteed to run @ 1333mHz, 9-9-9-24 by the manufacturer. So that means it should run stable up to 1333mHz with those timings.

With this in mind I purposely bought 1600mHz RAM with the intention of running it at 1333mHz and tighter timings although I'm still fighting my RAM trying to tighten it up. 2x4GB G.Skill Sniper 1600mHz 9-9-9-24 @1.5v [stock ratings]. My BIOS did recognize them at 1600mHz right away but set my timings to 11-11-11-28 on auto... ewww. So, through trial and error, I've been able to drop my speed to 1333mHz and timings to 8-8-8-22 @ 1.515v on a NB OC of 2.6gHz @ 1.250v. I've tried using 1T but fail P95 almost instantly, even after upping to 1.6v. I've tried running 7's on 2T but also fail P95 almost instantly. Just wondering if anyone else out there is using this RAM and if so, what timings/voltages you are able to get out of it. I'd hate it if I am at my tightest already, I'm jealous of others with 6-6-6 timings...

Thanks,
