RAM questions. Built my first computer, no idea...

Hi again guys,
I'm back with yet another problem =[. I just built my first computer (YAY ME!) but I'm having some problems with the RAM. I bought 2 sticks of 4GB each RAM. Running at 2333. Sadly, it's only showing that it's running at 1600. I'm not sure if I should overclock it (if you can even do that with RAM) or just let it be. If I should overclock it, how in the heck do you go about that? I really appreciate all your input.

Thanks again.

hi drumorgan this is the list of supported memory for ur mobo

http://www.gigabyte.com/products/product-page.aspx?pid=...


and this is the spec of ur mobo for rams :


* Due to Windows 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than 4 GB.
Dual channel memory architecture
Support for DDR3 2133/1866/1600/1333/1066 MHz memory modules
Support for non-ECC memory modules
Support for Extreme Memory Profile (XMP) memory modules

this is mean the maximum ram for ur mobo is 2133
try to check ur bios to c the value of ur rams and replay us

Hi, just leave it at 1600 it's more than enough, and it's because your motherboard natively supports ddr3 1600 and not 2133 that's why it's not running at 2133



DDR3 2133/1866/1600/1333/1066 is what it says under Memory Standard.

I will check my BIOS to see what it says.


Edit: Alright, I went into my BIOS and this is what I got

BIOS Version F3

BCLK 101.84MHz

CPU Frequency 3768.50MHz

Memory Frequency 1901.10MHz

VCore 1.308V

DRAM Voltage 1.536V



Appreciate the help gents.


Edit yet again:

Alright, so I went into BIOS and changed something (forgot the name of it... but I know how to get back to it). I changed it to 21.33. Now my readings on my Memory Frequency are at 2172.90MHz

Is this going to hurt the RAM? Or is just a little bit faster than what its set at hurt it?

It doesn't say O.C. anywhere that I can see =/

BIOS - IMO use F4 and not F5 or beta, the 22nm BIOS flashes have been causing too many 'new' problems. Wait for F6/F7.

As far as setting the RAM to DDR3-2133 11-11-11-30-2N @ 1.50v

CPU: | blank | 4GB | blank | 4GB |
failure: {though not documented, often one set of DIMM slots works better at high frequencies}
CPU: | 4GB | blank | 4GB | blank |

Easy:
The simplest is to set the XMP in the BIOS:
Extreme Memory Profile (X.M.P.) -> Profile1

Manual:

BIOS:
BCLK/DMI/PEG Clock Control -> Enabled ; it's best to set the BCLK for OC'ing the CPU
BCLK/DMI/PEG Frequency -> 1000 / 100MHz ; it's best to set the BCLK for OC'ing the CPU

Advanced Memory Settings /Enter
System Memory Multiplier -> 21.33
Performance Enhance -> Extreme ; problems use Turbo
DRAM Timing Selectable -> Quick
-
CAS Latency Time -> 11
tRCD -> 11
tRP -> 11
tRAS -> 30
-
Command Rate (CMD) -> 2
-
QPI/Vtt Voltage -> 1.125v
DRAM Voltage -> 1.50~1.55v ; high 1.55v if unstable
