GA-X58A-UD3R question

[rcorrea]

So I am new to this and I did download the bios pdf guide and i still have questions.

I have a GB GA-X58A-UD3R motherboard

I just purchased Patriot Viper 2 Sector 7 Ram 12GB kit, 4GB X 3 dims for a total of 12GB
I also have Patriot Viper Ram 6GB kit, 2GB X 3 dims for a total of 6 GB

I would like to install all 6 dims for a total of 18GBs if possible.

Both Dims are PC3 - 10666 @ 1333 Mhz

Both in Bios and Windows 7 64bit it shows 10GB usable and 8 missing. I have a dedicated graphics card so i know its not reserved.

How can i configure my bios and windows to use the whole 18GB if possible

What is your Windows x64bit version?

 

[nikorr]

To be able to address more than 16GB RAM, u need to have W7 Pro and higher windows.

 

[nikorr]

U need to place the 4GB sticks in to the Blue slots and 2GB in to white.

I have win7 home x64

Is it possible to do that configuration ? Also once I change the dims around is their any thing I need to change in the bios?

Try only 16GB.

 

[nikorr]

You know, if u use the different sizes, than u don't have your RAM configured in the triple channel mode, but it is flex mode, so performance is lower.

But it is nothing to worry about.

 

[rcorrea]

So would it be better idea to just use 2 12gb kits and win7 pro to avoid all this confusion? I'll move the dims around in the morning and see what happens

It should work, just not in the triple mode.

 

[nikorr]

BTW, do they have the same voltage, the RAM sticks?

I am not sure where would I find that out?

 

[nikorr]

CPU-Z @ http://www.cpuid.com/softwares/cpu-z.html

 

[nikorr]

On the butom @ Voltage.

 

[rcorrea]

Slot1 1.50 1.50 1.50 1.650
slot2 1.50 1.50 1.650
slot3 1.50 1.50 1.650 1.500
slot4 1.50 1.50 1.650
slot5 1.50 1.50 1.650 1.500
slot6 1.50 1.50 1.650

I moved the dims but now it shows 8gb lol

 

[nikorr]

OK, do u see there is a part #, post 1 for each type.

[nikorr]

They are OK @ 1.65V.

So what do I need to do to get the full memory of the ram to work

 

[nikorr]

Go to msconfig and check if the Max. memory is clear...

 

[jaquith]

Install:

CPU: | 2GB | 4GB | 2GB | 4GB | 2GB | 4GB |

BIOS: DRAM Voltage -> 1.64v and if needed QPI/Vtt Voltage -> 1.35v ; save & exit = yes

ill check that out

 

[rcorrea]

Install:

CPU: | 2GB | 4GB | 2GB | 4GB | 2GB | 4GB |

BIOS: DRAM Voltage -> 1.64v and if needed QPI/Vtt Voltage -> 1.35v ; save & exit = yes

would that be for all dims or just some?

 

[jaquith]

The voltages goes across all DIMM slots, and otherwise the 4GB is in the primary DIMM per Channel and the 2GB in the secondary DIMM slots per Channel.

When I searched both sets they're 1.65v at DDR3-1333 9-9-9-24-2N.

BTW - duh, I forgot LGA 1366 defaults @ DDR3-1066 so add: System Memory Multiplier -> 10 ; 10 * 133.33 is DDR3-1333.

Recap:

1. Install CPU: | 2GB | 4GB | 2GB | 4GB | 2GB | 4GB |
2. BIOS:
System Memory Multiplier -> 10
DRAM Voltage -> 1.64v
QPI/Vtt Voltage -> 1.35v
* CAS Timings

Save & Exit = Yes

Good Luck!

--

To set the CAS Timings:
BIOS: {* CAS Timings}
Extreme Memory Profile (X.M.P.) -> Disabled ; MUST be Disabled in ANY mix!
DRAM Timing Selectable -> Quick
CAS Latency Time -> 9
tRCD -> 9
tRP -> 9
tRAS -> 24

Thanks for this info, i am going to try it out and see what happens. BTW would you prefer just to use the same memory across the board instead of mixing? if so would these settings still apply?

 

[jaquith]

Personally, I never mix densities, IC's, or any mix, but if after the configurations above and works next is to create a bootable CD/DVD of Memtest86+ (ISO/zip file). Run for at least 4 passes or tonight overnight. Memtest -> http://www.memtest.org/ then you'll know.
