Question : ARES F3-2133C9Q-16GAB

[PowerK]

Hi folks.

I'm currently using G.SKILL ARES F3-2133C9Q-16GAB (16GB) memory.
Spec here : http://www.gskill.com/products.php?index=489

My brief system spec is as follows :
3770K @ 4.5 GHz
AsRock Fatality Z77 Professional
G.SKILL ARES F3-2133C9Q-16GAB

The G.SKILL memory is rated to run at 2133MHz @ 1.65V with 9-11-10-28 2T timings.

I'd like to know if there's anyone here successfully have them running at 1T instead of 2T ?? (with Memtest, LinX etc stress test passed).

Can try it, as is, or maybe try with an extra + .03 to + .05 to the DRAM voltage.....and maybe someone who has done it will chime in

[GSKILL TECH]

4 modules will most likely be 2T, especially at DDR3-2133

Thank you

Thanks for the input guys.

I just tried 1T and Windows showed BSOD while booting.

[Tradesman]

Could try with looser timings, but would be slower than with the 2T and tighter as is now. Some just aren't happy at 1T

[GSKILL TECH]

No problem with 2T anyway, it's not like you will notice a difference at all.

Thank you

I'll settle with 2T. Thanks guys!

[Tradesman]

No problem, Enjoy!

Here's the difference. It makes a little difference, but not noticable and not worth the work to get it stable, which I never did.

With 2T



With 1T

Cool.

By the way, this memory should have no problem running at 1600MHz with 9-9-9-xx timing + 1.50V, right?

Not sure what value I should put for RAS# Active Time (tRAS). It's 28 at 2133MHz.

I ask because lowering this G.SKILL memory from 2133MHz (1.650V) to 1600MHz (1.50V) might help overclock my 3770K further. (It's currently at 4.2).

[Tradesman]

Not at all, better timings would prob 8-8-8-24 or even 7-7-7-22

[PowerK]

Not at all, better timings would prob 8-8-8-24 or even 7-7-7-22

Are you saying the G.SKILL memory I have can run at 1600MHz with tighter timings than 9-9-9-xx ?

Also, decreasing 2133 to 1600 and voltage from 1.65V to 1.50V should lower temperature on my 3770K, right ? (Or does this not have any impact on CPU temp) ?

[Tradesman]

Yes, to underclock a set of DRAM is the opposite of OCing, normally if you took the 2133/CL9 set up to 2400 you'd raise CL to 10 and add voltage, likewise, when you underclock, you can tighten timings and lower voltage - it might take a little experimentation, but at 1866 should probably be able to hit 8-9-9-28/29 1.6 or so, and at 1600 8-8-8-24/26 at 1.55 or possibly even down to CL7....might take a look at this thread:

http://www.gskill.us/forum/showthread.php?t=10602

which are some basic results I got from playing with some sets of sticks (4x4GB and a 4x8GB set) the 1866 set was native 9-9-9-28 and took those up to 2133 and down to 1600 (and listed loose timings - didn't really push the timings that much - which is why I say you can prob run your set at a CL7 base for 1600.
