Odd o/c settings with NF4 DFI EXpert

[Guest Retratserif]

I have the same issue. I cannot get mine past 2805 without it crashing. I have booted in widows and complete a 32m Super PI @ 2950 but crashed as I hit the done button.

 

 

 

Try these settings.

 

 

Genie BIOS Settings:

FSB Bus Frequency - 240, 245, 250, 255

LDT/FSB Frequency Ratio - 3

CPU/FSB Frequency Ratio - 11

PCI eXpress Frequency - 105Mhz

 

CPU VID StartUp Value - Startup

 

CPU VID Control - 1.55v

CPU VID Special Control - Above VID * 102%

LDT Voltage Control - 1.20v

Chip Set Voltage Control - 1.52v

DRAM Voltage Control - 2.7V

 

DRAM Configuration Settings:

 

DRAM Frequency Settings: 9/10

Command Per Clock (CPC) - Enable

CAS Latency Control (Tcl) - 3

RAS# to CAS# delay (Trcd) - 04 Bus Clocks

Min RAS# active time (Tras) - 08 Bus Clock

Row precharge time (Trp) - 04 Bus Clocks

Row Cycle time (Trc) - 12 Bus Clocks

Row refresh cyc time (Trfc) - 16 Bus Clocks

Row to Row delay (Trrd) - 02 Bus Clocks

Write recovery time (Twr) - 02 Bus Clocks

Write to Read delay (Twtr) - 01 Bus Clocks

Read to Write delay (Trwt) - 02 Bus Clocks

Refresh Period (Tref) - 3017 Cycles

Write CAS Latency (Twcl) - 01 (Depending on your Bios this may be defferent.)

DRAM Bank Interleave - Enabled (If undstable turn this off)

 

DQS Skew Control - Auto

DQS Skew Value - 0

DRAM Drive Strength - 7 (if unstable lower 2 at a time while testing)

DRAM Data Drive Strength - 3 (if unstable lower one at a time testing)

Max Async Latency - Auto

DRAM Response Time - normal

Read Preamble Time - Auto

IdleCycle Limit - 16 Cycles (if unstable, go up in number one at a time testing)

Dynamic Counter - Disable (May or may not help with stability or performance, needs testing once stable)

R/W Queue Bypass - 16 x

Bypass Max - 04 x

32 Byte Granularity - Disable(4 Bursts)

 

 

Will be testing different ram soon.
