question about ram speed on a 4.0 ghz

post #1 of 4
Thread Starter 
i have overclocked by i7 950 to 4.0 ghz on 23x 175

the new ram i bought is the ripjaw x 8gbxm. the ram is rated at 8 8 8 24 at 1600 however with my 4.0 its currently at 8 8 8 24 1400

does that mean my ram is not running as fast as it should be? shouldi make it 2:10 and let it run at 1738?

The numbers in timings are actually the number of (CPU) clock ticks memory waits before starting the next step of whatever it's doing. So, 1400 is actually faster than 1600 since it only waits 1400 clock ticks, not 1600.

And timings are rather unimportant with DDR3 memory. Speed is king. 9,9,9,32 may be a lot faster at 2000mhz????

Oh! Oh! A little knowledge is dangerous.

Yes, theoretically 7, 7, 7, 21 would be faster, but, it's also lkely the memory could'nt run at 1800mhz with those timings, maybe 1400-1500mhz.

You need to do a lot of reading and trial and error testing for stability/performance.

Be aware though that messsing with memory is dangerous. When memory becomes unstable, a little, the computer just crashes, but pushed too far and the memory starts making read\\write errors and that sends data to bit heaven. What data? Any data...OS gets corrupted kind of stuff.

I've played around quite a bit with memory over the years and some amazing results are possible, with enough trial and error. Just as an example, there are over 30 "timings", not just (the commonly adjusted) four, you can reprogram whatever timings you want into memory modules, yes, make your own SPD, memory runs cooler without any heat spreaders, and many memory "timings" don't make the memory faster, but make it more "stable" so other timings (that make it faster) can be set or the speed increased or both.

Good luck and go slow!
