TwinX 2048-3200C2PT detected as 3-3-3-8

[BobJ]

I have just built a new system and chose TwinX 2048-3200C2PT memory 2-3-3-6 to make the most of the system.

 

Both my MB and CPUZ detect the SPD as 200MHz 3-3-3-8 even though CPUZ detects each stick as CMX1024-3200C2.

 

I know I can over-ride these settings (any suggestions on OC settings) but is the SPD reading wrong or are my stick wrong?

 

Many thanks

To answer your question:

 

The XMS 3200C2 series modules all use JEDEC-standard SPDs programmed with JEDEC-reference timings for DDR400/333/266. Moreover, the only JEDEC-standard CAS timing for DDR400 is CAS 3.

Set them like so:

CAS Latency (tCL): 2

RAS to CAS Delay (tRCD): 3

Row Precharge (tRP): 3

Active to Precharge Delay (tRAS): 6

 

Memory Voltage: 2.75 Volts

All other settings to defaults.

Many thanks for the prompt replies guys, much appreciated.

 

I’ll set them at 2-3-3-6 manually and be happy.
