most out of PC3 2300 18400

I finaly built my self a decent system with this ram, i noticed if i dont mess around in the bios my system wont even load, does anybody know the settings i can use to squeeze the most out of it.

System

GB x58a UD9
Core i7 950
4gb 2300 (18400) Dual, i know my board can do triple as well
GB gtx 470 SOC

It will be difficult to reach DDR3-2300. I would suggest some DDR3-2000 settings first.

Try this:

In MIT (MB Intelligent Tweaker):

CPU Clock Ratio - 20x
QPI Link Speed - AUTO
Base Clock Control - Enabled
BCLK Frequency - 167
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 12

Uncore & QPI Features
Uncore Frequency - 4008

DRAM Timing Selectable - Manual

CAS Latency Time - 8
tRCD - 11
tRP - 8
tRAS - 28

Enter these for the other three as well.

Channel A Timing Settings

Advanced Timings
Command Rate - 2

Advanced Voltage Control
Load-Line Calibration - Disabled
CPU Vcore - 1.32V
QPI/VTT Voltage - 1.50V (You will need to find the stable voltage your CPU needs at each frequency)

DRAM Voltage - 1.640V
Rest to AUTO

Thank you

Im just being stubborn, i have it stable at 2000mhz, running at 4.0ghz i just wanted to try to squeeze more out of it, it will not even boot if i try to bring it up, the MOBO hangs at C1 on the led.

What is your QPI/VTT Voltage? This needs to go up as you increase frequency.

QTT.Vtt 1.515V

QTT.Vtt 1.515V

Will probably need more than that to hit the higher speed - something in the neighborhood of 1.55v or possibly higher

You might also need to bump other voltages

PCIe [1.60v]
CPU PLL [1.86 - 1.90v]
IOH Core [1.20 - 1.30v]

Ill give that shot when i get back from Vacation in a week, if it doesnt work ill post again thanks fellas

So i can get it to boot up at 2100 mhz the ram that is but only 4 out of 8 gig are running, and it sure isnt stable, any suggestions

How do I raise the Ram Freq a little bit at a time, im fairl new o this stuff.

[GSKILL TECH]

Adjusting BCLK is how you adjust RAM Frequency a little at a time.
