GA-EX58-UD4P and F3-12800CL9T-6GBNQ

[Kaipo]

I'm a total beginner at configuring anything computer related and I can't get my ram to run at the 1600 rated speed. After looking at a thread here from a person with the same mobo and memory, I tried entering these values and ended up with nothing but my pc restarting itself and sending me to a black screen. Here is what I have and what I've done.

Intel I7 920 C0
Gigabyte EX58 UD4P with bios F13
6gb F3-12800CL9T-6GBNQ
EVGA 01G-P3-1281-AR GeForce GTX 285 1GB 512-bit video card
Windows Vista x64

CPU Clock Ratio = x20

BCLK = 160

Uncore Freq. = x20
QPI Link Speed = x36
Performance Enhance = Turbo

Memory Mulitiplier = x10
XMP Profile = Profile1 (which gives the timings below)
DRAM Timing Selectable = Auto

CAS Latency - 9
tRCD - 9
tRP - 9
tRAS - 24
Command Rate - 2

CPU VCore = 1.3V
QPI/VTT Voltage = 1.55V
CPU PLL = 1.8V
IOH = Auto
ICH = Auto

DRAM Voltage - 1.56V

What am I doing wrong?

[Tradesman]

Is Command Rate at 2T? Do you have the latest BIOS? May want to input the base timings manually (AUTO can fluctuate) and wouldn't rely on XMP (different mobo makers implement it differently and can cause problems), What is your tRFC? What slots are the sticks in? Could you post your BIOS settings?

[Kaipo]

What slots are my sticks in? Do you think I'm an idiot or something? Well I am. This is thoroughly embarrassing; I had the sticks in the 3,6,5 slots rather than the 1,3,5 slots. This was my first attempt at building a pc and I completely slipped up there.

I reentered the values and the system is up and running. The command rate is 2T and I'm running the latest bios. The timings have been entered manually too. I'm not sure what/where the tRFC is located.




Here are my bios settings.

Should I make any changes? Should I run prime95 for a while to make sure I'm stable?

[GSKILL TECH]

Looks good, besides QPI/VTT Voltage being slightly low, but run Prime95 and see if it is stable. If not, simply increase the QPI/VTT Voltage. Also, make sure to watch CPU temps when you run burn tests.

Thank you
