Hi i've got above board, and also

Corsair TwinX2048 XMS3200 CL2

But when looking up what exactly i need to do to set the best settings i get very confused: the bios on tha ASUS has so much more information then the usual 3-3-3-7 type setup. And i'm not willing to try things out on it (production machine)

These are the BIOS settings

* Memclock Value: 100, 133, 166, 183, 200, 216, 233, 250 MHz [200 i presume]
* CAS Latency (CL): 1.5, 2.0, 2.5, 3.0, Auto [=3 but the memory specification says it should do 2]

The next ones i just find very confusing

* TRAS: 5 - 15 CLK, Auto
* TRP: 2 - 6 CLK, Auto
* TRCD: 2 - 6 CLK, Auto
* TRRD: 2 - 7 CLK, Auto
* TRC: 7 - 22 CLK, Auto
* TRFC: 9 - 24 CLK, Auto
* TRWT: 1 - 6 CLK, Auto
* TREF: 3, 9, 7.8, 15.6 us
* TWCL: 1, 2 CLK
* R/W Queue Bypass Count: 2, 4, 8, 16 CLK
* ByPass Max: 0 - 7 CLK
* Idle Cycle Limit: 0, 4, 8, 16, 32, 64, 128, 256 CLK
* DDR Driving Strength: Normal/Weak
* Enable 32-byte Granularity: Enable/Disable
* Twr - 2 - 3 CLK
* DDR Input Strobe Skew: Disabled/Slower/Faster
* DDR Data Driving Strength: Disabled/15%/30%/45% Reduced
* Read Preamble: 2.0 - 9.5 ns, 0.5 ns increments
* Async Latency - 4.0 - 11.0 ns, 1.0 ns increments
* Bank Interleaving: Auto/Disable
* Burst Length: Auto/Disable

CPU- z says the following:

Northbridge nVidia C51XE rev. A2
Southbridge nVidia nForce4 MCP rev. A4
Graphic Interface PCI-Express
PCI-E Link Width x16
PCI-E Max Link Width x16
Memory Type DDR
Memory Size 2048 MBytes
Memory Frequency 200.9 MHz (CPU/12)
CAS# 3.0
RAS# to CAS# 3
RAS# Precharge 3
Cycle Time (tRAS) 8
Bank Cycle Time (tRC) 9
DRAM Idle Timer 16
Command Rate 2T

But also that the memory says that these are it's specifications (ie contrary to the memory manual)

Timings table
Frequency (MHz) 200
CAS# 3.0
RAS# to CAS# delay 3
RAS# Precharge 3
TRAS 8


Basically the memory is tested for 2-3-3-6 but how do i set those settings with all the bios options above?

Sorry for delay, I must of missed this post.

CAS=2 (or TCL / CL sometimes)
TRCD=3
TRP=3
TRAS=6
