AsusP5N-E & TWIN2X2048-6400 Settings Help


Recommended Posts

Hi All


This my Pc Kit & BIOS Setup :



Pentium Duo Core (E2160) 1,800 GHz (800MHz FSB)

ASUS P5N-E Sli Mobo

Corsair TWIN2X2048-6400C4 G Memory (2 x 1 GB (DDR2) Paired Modules)

Freezer 7 Pro CPU Cooler

GeForce 8400 (256Mb GDDr2) Graphics Card

EZCool (650W) Power Supply


Current (Stable) BIOS Setup:


A1 Tuning = Manual

NB PCIE(MHz) = 100



VCore = Auto

Memory Voltage = 2.085v

NB Core Voltage – Auto

VCore Offset Voltage = Auto


Memory Clock Mode = Unlinked

FSB Memory Ratio = Auto (Greyed Out )

FSB (QDR) = 1240

Mem (DDR) (MHz) = 800

SLI- Ready Memory = Disabled


CPU Multiplier = 9

CPU Internal Thermal Control = Auto

Limit CPU ID MaxVal = Disabled

Enhanced C1 (C1E) = Disabled

Enhanced Intel Speedstep Tech = Disabled


Memory Details:


I’d like to mention after much ‘Forum’ Info searching, a little luck and a wealth of Advice I’m now able to use my DDR2 paired Memory in either the ‘Yellow’ or ‘Black’ Paired Slots as they were meant to be used !!

This was not the case on 1st Build (Only worked in Banks A1 & A2 )

All 2GB were recognised but only as ‘Single’ in CPU ID program !!

Now all OK Id’d as Dual and Passes Stress Test in MemTest86 and suffers

PRIME95 x2 (100% CPU Loaded) all day !!


I’ve achieved an OC to 2,750 GHz and am pleased its all Stable and agood % OC

But I know many of you out there have easily exceeded 3,000GHz


Can anyone suggest improvements to my Mobo/Bios Settings to reach the 3,000GHz OC without Breaching Warranty Limits or killing any of my Kit.


I’ve read many Forums on OCing and my brain is now amess with OC info so if anyone can help clear some clouds/cobwebs with suggestions or Settings please fire away.


Thanks All from a 1st Time (UK) Nooby !!!

Posted here also to possibly help other Frustrated 'Like' Mobo/memory Sufferers !!!

Long Live Forum Folk' !!!

I Read Your Report On The Asus P5n-e-sli Motherboard And I Am Having Problems Getting The Two Sticks O Memory To Work.

The Motherboard Will Work With One Stick In The First Slot

But With Two Sticks, I Get Errors On The Mem Test.

Can Anyone Tell Me How To Get This Motherboard To Work Without Errors Using 2 Sticks Of Memory?
