ASUS ROG STRIX X99 - Memory request

[ghostfox]

Hi to all,
i'm going to buy a new X99 ROG STRIX motherboard, but i have one question about RAM:

I have 2 X KIT of 4x8GB (32GB Kit) Corsair Dominator Platinum for total amount of 64GB ( model number: CMD32GX4M4A2400C14 )

on the memory compatibility list of that MOBO, i see that (attach):


what is the correct reading about that?
i see triple DOT = 8 DIMM supported
BUT
i see model is ONLY 32GB kit (4x8) on the model number.

is that OK for 64GB or is MAXIMUM supported 32GB in 8 Dimm module? :confused:

thanks in advance for every explanation...

The C14 in the name suggests.... Cas 14 for 2400....you can aleays set XMP in BIOS...check primary RAM timings and then reset BIOS and input settings yourself.

Or primary timings should be listed on sticks themselves....on the label

Otherwise you are just stuck with default timings and frequency

For example 15-15-15-36 is the default for that kit at 2133

But it is rated at 14-16-16-31...which is what you should input at 2400 to try and run at rated specs....

OK thank you Arne, i check this evening or tomorrow... ! 😮

Righto! Let us know how you get on 🙂

Ok I've tested yesterday evening but:

if i use:
1 attempt: 5820k 4.3ghz RAM 2133 voltage Auto (1.9 see on bios)
the system is totally stable.

2 attempt: set 2400mhz RAM, voltage 1.3 (same cpu clock) timing like corsair setting 14-16-16-31
system during play crash on windows so many times (nothing happen if i use windows ONLY and not gaming)

3 attempt:
same to second, i try to change RAM voltage to 1.35 but nothing change, crash during games - no problem on windows.

Advice?
I see corsair test the 2400mhz Ram with 14-16-16-31 with voltage 1.2 ...
1.2volt is on standard setting also, like 2133mhz.. .

[Arne_Saknussemm]

What voltage is 1.9 in BIOS ghostfox?

1.2V will indeed be the rated voltage for one kit....you have mixed two kits so all bets are off RE. specified voltage.

What does the BIOS show for DRAM voltage and VCCSA (sytem agent voltage) after you have set 1.35V?

Maybe you should separate the two kits and verify that they work individually at rated volts and timings....you can do this by the serial numbers on the sticks...they will be sequential for each kit....

Sorry Arne,
1.9 > 1.19 Ram in standard settings. .. missing "1" at the beginning of "9" ... :confused:
I have to try VCCSA voltage now!

i have been tested only with 1.3 / 1.35 on RAM , nothing others option... You suggest another parameters to set manually than RAM and VCCSA?

[Arne_Saknussemm]

VCCSA can play a big part in getting stuff up and running, yeah...I'd be interested to know what the board is setting...

There are other options in the Digi+ section I'd look at. Like setting phases to optimized or extreme for DRAM, as well as increasing current capability for RAM to 120% or 130% on the two channel pairs

VCCSA can take time to tune on this platform....too much can be as bad as too little but I would have a look around 1.1v for a quick and dirty start

ok i try to start at 1.1 on VCCSA with 1.3 on ram same 14-16-16-31 timings..
i can't have experience about ROG bios and sorry for my repetitive questions.

Optimized or Extreme for Ram ok.. i check.
Anyway, i'm disabled on XMP.

Nah...no worries...we were all new to doing this once 😄
