12GB (3x4gb) F3-12800CL9-4gbrl configuration

[Dgrasshopper]

HI!

Im using this 3 modules of F3-12800CL9-4gbrl in a ASUS P6X58D-E for a total of 12GB.

First of all, this ram is not in the QVL for that mother, but since in Newegg there were people saying that they do the match i bought them.

So, they work fine so far!

I had some BSOD but i blame the psu or the video card for some reasons.

Ok....i have the I7 930 overclocked to 3,6 ghz 171x 21 and the RAM in Cpuz:

684 mhz (2:8)

9, 9, 9, 25, 107 COMAND RATE 2


After doing some tweaking and checkind the stability and performance it looks to me that:

For 12GB is better 1333 mhz aprox, command rate 2, those 99925 latencies, and the voltage more close to 1.6 than the 1.5 specified for this modules.


I really want to hear for some of you or why not....the nice GSkill forum support, what do you think about all of this.

Im using the configuration for profesional 3d animation and rendering so i dont think that pushing the OC in either the cpu or ram would be that good idea.

But i find 3.6 ghz for cpu and 1333 aprox for ram in tripple channel is a nice sweet spot wich alows me to leave the pc rendering for 10+ hours without passing the 70 C.


OTher hardware involved:
quadro fx 580,
psu 450 wts vitsuba,
coolermaster 212 plus
3 HD sata 2 7200rpm

Voltages

cpu 930 ..... 1.12 v

dram bus voltage....1.58v

qpi/dram vol....1.275v

pll 1.82v

The uncore is running at 3247 wich is more than just the double that has to be, bu t i think is better this way, not sure though.

Thanks, any suggestion, opinion or tip about this thing of running 12 gb of ram, in general or specific to my case, woulb be appreciated!

Cheers, thank you!

Looks pretty good, Big thing is that it's working 4 u w/ what u want/need to do.......can always write down all your BIOS settings and then when u have some free time try tweaking it further, i.e. DRAMs at 1368 w/ 9-9-9-25, maybe tighten it down starting at 8-9-9-25, dropping the CL will boost performance

Wow, fast reply, thanks.
yesterday i did some cinebench 11.6 benchs, tweaking only the ram frequency, latency, and comand rate.

i even run the test at 8 8 8 22 cr1 at 1368.

When i saw more gain was while lowering the tRAS from 25 to 22.

I had the ram running at 8 8 8 25 and when i saw that it should be 22 for that lats,

cinebench gave 6.2 vs 6.06....by only changing that value.,,,interesting.


So would you iluminate me a little more about voltage and comand rate?

That 1.58 v and comand rate 2 that i feel is improving stability has some fundation?

Cheers, maybe with free time i will do some benchs and posting here for everyone.

Thanks again.

With more voltage, it can be more stable, but if it is already stable, no need to add more.

If you increase to 1.65V, it may be capable of DDR3-1500 to DDR3-1600 8-8-8-24.

That is something you can test and try out.

Thank you

Thanks, good to hear that!! i shure will do some tweaking to check that.

My concern was more about frying the modules with 1.6 or more, because they say 1.5 as default.

I dont really need a reply to this, but i say....the mem ok led of the asus p6x58d-e board is always red when starting the pc....im not concern because if things are working....who cares about that led......but maybe there is some reason and i just dont know. Not big deal at all.

Great support GSkill!!!! amazing, keep it up!

Cheers

That is normal, they will all blink when you first start the computer, but will shut off later. If they stay solid, then that means something is wrong. Since you say it is working fine, the light is probably gone after you boot up.

As far as voltage, memory can be overclocked and overvolted, you just need to know how/why to do it. For example, if your memory is unstable, it does not mean raise DRAM Voltage 1.70V, 1.80V+++ That is not right. But if you increase frequency or lower timings to overclock, raise voltage to 1.60V+, that is no problem. Advanced overclockers can run this memory at DDR3-2000+ and higher than 1.65V, but that is still OK for the memory since it is using the extra voltage. Of course the memory has to stay cool..

Thank you

Exactly ...the led only gets red at booting, then shut off. Glad i bring the point , know i have even more peace of mind (about my hardware stuff at least, ja!).

Thanks again, lets see if in a near future i can make some everest/cinebench/sandra benchs very detailled to post here. At this point of the very good costumer/support relationship, i can also offer to run any bench or do any specific tweak to the bios if that helps in any way. Just let me know....benching and testing hardware is a hobby for me anyway.


Cheers.

Appreciate it, doing that type of stuff is definitely more fun when it's a hobby, as opposed to having to do it

Have a gud 1 ! and we'll be looking for u
