Asus P5Q SE QUAD2X4096-8500C5DF Problem


Recommended Posts

Hi, I can't get my system to post with my QUAD2X4096-8500C5DF Ram. I have tried changing many bios settings and still can't get the system to post . I have tried this ram on my Asus P5Q SE and my Gigabyte GA-P35-DS4 and can't get either system to post. When I put generic kingston ram in my Asus P5Q SE it boots without a problem.


I have tried the ram in different slots, by them self, in pairs, in pairs with different channels, etc.


Any ideas?

Download Memtest Version 2.11from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from

Insert a single stick in the first slot (Closest to the CPU) and enter your BIOS, set to these values:


AI Overclock Tweaker

Ai Overclock Tuner = Manual
CPU Ratio Setting: 9
FSB Frequency = 266
PCIE Frequency = 100
FSB Stap to Northbridge = 266 Mhz
DRAM Frequency = 1066Mhz

DRAM Timing Control = Manual

CAS Latency = 5
DRAM RAS# to CAS# Delay = 5
DRAM RAS# Precharge = 5
DRAM RAS# Activate to Precharge = 15
RAS# to RAS# Delay = Auto
Row Refresh Cycle Time (tRFC) = Auto
Write Recovery Time = Auto
Read to Precharge Time = Auto
Command Rate = 2N(T)
All other to Auto

DRAM Static Read Control = Auto
DRAM Read Training = Disabled
Mem. OC Charger = Auto
AI Clock Twister = Auto
AI Transaction Booster = Auto

CPU Voltage = Auto
CPU PLL Voltage = Auto
FSB Termination Voltage = Auto
DRAM Voltage = 2.1v
NB Voltage = 1.25v
SB Voltage = Auto
PCI-E SATA Voltage = Auto

Loadline Calibration = Auto
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
Clock Over-Charging Voltage = Auto
CPU GTL Volage Reference = Auto
NB GTL Voltage Reference = Auto

Legacy USB = Disabled for Memtest, Enabled afterward.

Shut the system down. Boot to the Memtest CD with that single stick and allow for two full passes. Shut the system down. Remove the first stick and insert it in slot three. Repeat Memtest. Shut the system down. Remove the first stick and insert the second stick in slot one. Repeat Memtest. You have now tested both sticks in single channel mode.


Now test for the Dual Channel Mode function of the memory controller. Insert a stick in slot one and three and Memtest. If Stable enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.

Thanks, I will try this as soon as I get a chance.


The only way for me to make changes to the bios is to use a stick of generic ram.


With the corsair modules my screen stays black.
