Ram overclocking tutorial + some questions?

post #1 of 8
Thread Starter 
Heya, I'm looking for a detailed ram ocing tutorial, couldn't find any beyond "increase voltage if your timings don't work" I also want to mess around with the secondary timings etc, but I don't know what most of them mean.

this is my ram atm
http://www.gskill.com/products.php?index=378

Can I increase it from 1.5 to 1.65/ go from 1866 to 2133 without reaching too high temps?
Is there any way to measure the temperature without a temp gun?

What are good benchmarking tools for quick stability test for ram? [can't run memtest86+ atm, not a single empty cd/usb stick around....lol]

you should be fine below 1.6V and youre temps will be fine. You really wont see much of a performance increase though, I personally would try to get CL7 or CL8 out of it @ 1866

I also get errors in prime when I set my 2N to 1T (will this also get fixed by increasing voltage?)

Not necessarily! I heard from many people that they had problems with t1.
That is why i never even tried it.

got it to 8-9-8-24-2T@1.65v atm first setup i tried after many fails for a succesful boot, can I get lower latencies if I play with the secondary settings?


my VCIIO is at 1.15 atm, should i make it higher?

does vccsa have anything todo with ram overclocking?

QQ i'm a noob

/edit: wouldnt be 2133 mhz better, since i heard freq > timings @ sandy bridge

Nope what i would do is lower the 28.
i would rather go for 9-9-9-25 or similar than 28.
And the secondary timing won`t effect your bandwith not (very) much.
Maybe you use a tool like maxxmem to benchmark your bandwith to see if 9-9-9-25 (or similar) is better than 8-9-8-28!

Since i have no SB-rig and therefore no SB-mobo i have no idea what they do - but the PROs here will be able to answer that!
But anyway:
Good Luck mate!

edit:
actually it doesnt work

can't get better timings at 1866 mhz within good voltages, Just forgot that resetting memory settignsi n bios via the hardware button resets ram speed to auto (= underclocked@1600)

I'm at 2133mhz 9-11-10-28-2 atm @1.65v, can't seem to get it any lower (I was at 1.7v to test if i coult get 9-10-10 or 9-11-9 stable but no succes,

overclocking ram also has the side effect that my gpu underclocks itself to 500 core mhz(880 stock)
