Hi! I got Gigabyte X58A-UD7 rev.2 motherboard, everything is running on basic freqs, voltages and timings...
But motherboard sees only 4Gb in 2133Mhz mode of memory..
Boots with 12Gb only on 1800mHz.
So my question is: how can i make this memory run whole 12Gb on 2133mHz?
Strongly like to do this, since it boots in4Gb on such frequency )
Thx in advance
Here's BIOS status to give you and idea..

I have also started the thread on g-skill forum, but they can't help me yet..
Here you can find the whole thread http://www.gskill.us/forum/showthread.php?t=8189
Please help me!!
This is really weird i guess...since it boots with 1800mHz without ANY issue!
Or maybe you could fix it with new bios...i've seen you got a new one in beta-test now...

Hi and welcome to the Gigabyte Forum.
Normally there are two different reasons why the system doesn't see all the memory.
One is bent pins in the CPU socket. The other is a too low QPI/Vtt setting. As this is the easy option I would try this first.
Try increasing the voltage until it is between 1.2 and 1.45 v. It is a case of "suck it and see". Also make sure that you are setting the memory voltage and timing manually. You will probably need to increase the memory voltage by 0.05v as well considering the extra load put on the controller because of the filled slots.
-
Thank you Dark Mantis !
Guess i have tryed that already, increasing voltage on CPU/VTT to 1.5 even - won't give any difference, still sees 4Gb :(
About bent cpu socket - impossible, i've checked it very accurately while buying / installing, and have installed cpu in super-accurate precise mode of myself :D than carefull gradually make my corsair watercooler on it...
So i guess and HOPE also that this is not hardware problem in this case! :)
And yeah, as 've said...It's strange than, than it sees this exact memory 12gb in 1800mHz mode (with x14 mode)
It's actually stable, but i strongly want to make memory perfomance as it is...
P.S. Timings have been seted manually just as spd memory profile, and my actions also have been confirmed by G-skill vendors multiple time...So this ain't the issue too i guess..
About voltage - i have a little doubts, coz when i'm setting DRAM 1.680, it actually shows 1.648 in Current system status...Needed voltage wor this RAM is 1.65, but i can't set it more precise then setting 1.68 :(
Also such a huge difference between setted and real values leads me to thought that voltages could vary a lot...which maybe leads system to instability in this case.
Please check out the screenshots, maybe they'll give you an idea, but the screenshot with voltages actually is 1.68 on DRAM, i've just take screen while testing out...other values i guess is the same in auto mode.
You will probably need to increase the memory voltage by 0.05v
How?
I thought this model can change only 0.1 step dram voltage...
-
You haven't got the memory setting configured manually at all! You have the XMP selected as Porfile 1 which is overriding any other settings you change for a start. ???
It wasn't CPU/Vtt that I said either it was QPI/Vtt.
-
Dark Mantis
My bad...I mean of course QPI/VTT
But about xmp...I wastring with or without - totallyno difference, i guess they affects only what will be setted in auto mode, ain't it so?
-
You need to disable XMP first and then you will have control over the settings for the memory. Ohterwise the XMP setting takes over.
Input all timings and voltage manually as I described and hopefully you will get your memory back.
-
Ok, i understand...
Just done this - exactly the same (actually last boot i use was without xmp already)
I have also tryed again to raise gradually the QPI/VTT as you have said - no luck :(
I found strange the fact that now i can boot full 12 Gb 1800mHz without problems, but 2133mHz...no way :(
So this sounds like non-sense, i mean at least it tells that all the slots and memory itself are not damaged and working..
P.S. You have said to input all the timings...But actually i got only the main 8 9 8 24 and 2T cmd rate, g-skill staff have said that other i should leave with auto..
-
Well it could be that your settings are still not right or the memory won't overclock to 2133 which is quite possible when you consider the highest JEDEC standard is 1333 Mhz.
You could try slackening off your timings a bit.
-
I can provide a new pictures of bios to get you full idea of current system state and what to do with this, should i do this?
Well, about memory - it totally can overclock to 2133mHz and it's timings CL8, coz damn, it works on this frequency and timings perfectly with 4Gb! I have payed aloooot of money for this memory, in my country it is actually best memory i could possibly get! I have waiting appearance of 2133mHz with at least Cl8, and now i got in this awful situation...
So i won't just loose my hands, there gotta be a solution, problem is definately not in memory or it's timings, i feel that this is BIOS / motherboard issue.
Of course i could try higher timings just to see if you're right...But this is not the solution.
P.S. Look at MIT screenshoot, it actually sees all 12Gb, but post that only 2 of sticks enabled..
update: 9 10 9 28 timings - same. I was right..
-
If you run CPU-Z it will allow you to see your memory details. Try that.

btw. why the hell it shows PCI-E x16, i thought that my motherboard have x16 ver 2, as my GTX580 do, ain't it?

tHe last picture wa sthe only one of interest but it shows the timings and voltage of the memory for 2133 setting. Did you check the other 5 slots to se if it shows the same?
-
Yep, all 6 eaxctly the same.
btw. why the hell it shows PCI-E x16, i thought that my motherboard have x16 ver 2, as my GTX580 do, ain't it?
Please answer, it's also interesting for me...If videocard actually works in x16 gen 2 mode
-
Yes your motherboard supports PCIE version 2.0 no problem. The x16 is the badwidth(speed) of the slot and bus. I hope that I have made that clear enough. If not please post back.
-
Yeah clear enough, thank you...Than we can back to memory...
-
Should i do something with
Cahnnel interleaving
Rank interleaving
or Channel x turnaround settings
?
Coz i haven't touch nothing of that, for the reason i don't know what the hell this is.
-
No don't touch any other settings for the moment.
-
No new ideas? :-\
-
Have you still not had any luck with it ?
-
Of course, coz i have nothing to try else since your post, i need an ideas)))
-
Cmon, throw me new idea to tryout!
I'm really stuck in here...
-
I am sorry but I have no other suggestions. I was hoping someone else like Lsdmeasap would pick up the thread and maybe see something I haven't.
I will ask him to take a look if he isn't too busy.
-
Ok, I see several things wrong here. For starters you are using fail safe defaults, so please go into the BIOS and load optimized defaults, then save/apply/reboot back to the BIOS. Once in the BIOS set your SATA/Disk settings to what you need again, then you can make any other changes you need before loading windows.
2133 memory is not made for X58, but you can probably run that way with some high voltages if you want since you have a 970 CPU. But also, that 2133 rating is for one kit, I kinda doubt you can run that fast with 12GB (3 kits) especially at the rated timings, at least not for daily use anyway.
This would be ideal settings to attempt 2133, but I would really advise something like 1866-2000 (And 2000 is really not ideal either with 12GB)
BSOD Error codes and what they mean:
0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
0X00000101 << Not enough Vcore Voltage
0X00000109 << Not enough or too Much memory voltage

Uncore Frequency .......................... This must be at least 1.5x your memory multiplier, but can go to 2x or above and higher like that may help with stability. Higher does = better performance too, but will require more QPI/Vtt voltage. So set x24 as your 1.5 minimum, but I would actually start by trying with this at x28 myself for now (For x16 memory multiplier).

Lsdmeasap
thx for your tutorial, but it still sees only 4 on 2133mhz, even while lowering voltages and raising timings :(
Well...seems i'm out of luck on memory :D
