Added DDR3 2400 to Rampage Extreme III Need Help

[jsfitz54]

Where is the BIOS reset button?

Should be near the mouse input.

Look at manual: http://www.asus.com/ROG-Republic-Of-Gamers/RAMPAGE_III_EXTREME/HelpDesk_Manual/

first line in 2nd information is where I set to 2T

Yes: 2N

You may need a cpu voltage boost for 24GB Ram, Max is 1.375V per Intel ARK
http://ark.intel.com/compare/47933

You have a dual bios setup, you can switch between the two with the red button near them. One may be old and need flashing to 1502. You do not do this with the mobo running. In standby mode, you should see LED light switch positions.

Have you looked at the manual yet?

What OS?

Fill out "System Specs" in user account.

Read through manual re: CMOS. OK. So I unplugged power and let it sit. Was able to reboot as it automatically reset BIOS. Set all variables as you suggested except DRAM Frequency and CPU voltage. It booted fine but still slow RAM speed. Then set DRAM Frequency to 2133 and rebooted. Froze up again. Have unplugged power and am letting it sit. So should I try it again with the higher CPU voltage? Or I'm thinking maybe remove 8 GB of RAM and see if I can get 16 GB to run at higher speed. Thoughts? Thanks.

You have a TRIPLE channel platform, run THREE sticks. You can run lopsided, but it may become an issue of itself.

CL9 is too much... Put them on the lowest slowest you can. And at least fine your stable settings.

Again... watch the uncore ratio! Your CPU needs low uncore maybe. Don't use auto FSB settings in OC/ CPU settings part. Think out what you do.

WTF. You don't understand the platform. Triple channel is not lopsided, that's how it was designed. Look it up.

It booted fine but still slow RAM speed. Then set DRAM Frequency to 2133 and rebooted.

Try 1333 then 1600 then 1866 and see how it goes. CPU, if set to auto voltage, may overboost check and see. Also DRAM voltage can go higher, try first bump past 1.65v. Do not try and overclock CPU, boosting ram speed automatically boosts CPU speed. My chip runs at 3.659 with 2133.

Try to run the ram at the 18xx divider.
I had a similar issue with my Z68. Turns out the engineers made the 1866 run faster than 2133.
It was discovered during testing here with then new Samsung ram few years go but I was more than happy it was as good and even better than most 2133 speeds when I use little higher bclk at 19xx..
Even at just base clock I'm able to run tighter timings, mostly sub timings tighter and still have very responsive system.
At first there was some thinking it was just from all slots loaded, ect but it was just an engineering issue the dev's did during making the BIOS work best with the cougerpoint chipset

Seriously?

What am I missing? it's three channels, while running 4 is ok, it's not optimal and mismatched...three will be in triple fhannel, one in single channel. why add more fomplexity to reach his goal with 4 sticks???

He is trying to run with all slots populated. 6 x 4GB. He can run dual channel but that is not his goal. Hell, he can run 3 x 8GB if he has some spare memory to try.

Yes, Seriously. You have made several bad remarks in this thread regarding x58 platform, which indicates you are not a know-it-all.

 

[EarthDog]

I am just trying to help. But, to be quite honest, I think you missed what I said.

I already noted that he was running with all slots (6) populated. He cannot seem to achieve his speed goal. I also noted to have less stress on the IMC to remove 3 sticks so he still has triple channel AND less stress on the IMC to reach his speed goals. He appears to want to try with 16GB which I stated isn't a good idea (due to mixed channels - triple and single). The point here is to K.I.S.S. This can be accomplished, as I said, with using 3 sticks, not 4 (again - he said in a post to run 16GB which is 4x4GB in his case).

So, where did I go wrong? Sorry if I missed something.. but there isn't a need for you to lash out and get personal.

I don't know why but i enjoy every thread where @EarthDog participate

From the manual: "Due to Intel spec definition, X.M.P. DIMMs and DDR3-1600 are supported for one DIMM per channel only." So is that something a tweaker would ignore or does that really mean that if I want faster RAM I need to go to three sticks?

And another question: Let's say I have to go down to 3 sticks so 12 GB and that allows me to run at 2400 or some elevated speed. Is that going to be better than having more RAM at a slower speed? I think the answer is yes unless I'm doing heavy video use where I really need the RAM. I had been functioning on this PC with 12 GB previously. It seemed slow compared to my much newer laptop which has 16GB and is running RAM at faster speed (without any tweaking). That is what led me to try more and faster RAM on the desktop.

I'm pretty polarizing... sometimes not in a good way. You either love me or hate me. Either way, doesn't matter to me.

Here, I have no idea what I missed outside of the names of voltages earlier in the thread (which I corrected when I saw it - well before fitzy got here). Its clear I know what triple channel is and how it works on X58. Its clear the dude wanted to try 4 sticks.....

I don't know. I will wait until fitzy gets back to see...

From the manual: "Due to Intel spec definition, X.M.P. DIMMs and DDR3-1600 are supported for one DIMM per channel only." So it that something a tweaked would ignore or does that really mean that if I want faster RAM I need to go to three sticks?

That passage tells me you cannot populate all 6 slots and run XMP. First time I have heard of that honestly.

As far as 12GB at 2400 or 24GB at 1600. That also depends. If you are close to breaking 12GB, I would say jump to 24GB and run it stock. The performance difference has proven to be nill in many cases (others, like fallout 4 for example, respond well... but this is rare).

 

[jack d]

Hmm. So I got it to work with 24 GB with DRAM Frequency of 934.4 using timing 9-11-10-28 2T. I wonder if it's ok or I'm going to run into trouble.

 

[EarthDog]

Only way to tell is to stress test it and use it. Use Prime95, Torture test, the blend test. That will give you an idea.

 

[jack d]

So far, after a small amount of use, it doesn't "feel" that much faster running 24 GB at 1866. Maybe I'll try running 12GB and see if I can get it to run at 2400.

Great job @JACK'd ! Pure MHz speed is not always faster. c.i.p. my setup.
We ran countless testing and it was as fast or even faster than some newer platforms at 2133 speeds.
O/Cing is always a gamble, but even by design some platforms just have better traits utilized than others. Some by accident others it is by design.
Even back in Z68 days the faster Ram was still newish and a lot not even officially supported, thus by grace some Intel engineers did make the best out of what they could achieve going to market.

Best now is get it all stable then try tweaking timings, and don't forget about sub-timings, they indeed play a good part of the game not just the primary numbers.
There is a boatload of work here at TPU from user input doing testing and bench's and should have plenty of timings to start tweaking to your hearts content.
Look at some of the reviews like what @cadaveca did here at TPU, you will find invaluable info on pretty much all aspect's of memory workings
I spent 2-3 months tweaking mine as it became apparent that not all Z68's were the same thus a lot of experimenting to where it's at today.
TBH I'm not sure it's still as good as it gets, but good enough for the last few years with Zero issues.
Take your time and enjoy
