P4N Diamond and Corsair RAM (Freeze/Restart) Solved


Recommended Posts

Finaly after 6 months the issue of my RAM is solved. Now P4N diamond Rocks with Corsair Twin2x1024A-5400UL module


Q: With only one stick memory, system works fine. However, when I plug the other memory to the MB to run dual channel, blackscreen or system freezes randomly. (Or I plug 4 sticks memory, system could not boot up.) How to deal with it?


A: First guarantee these memory are identical, for different spec memory working together easily causes issues. If it is guaranteed,please currently use only one memory to boot system up, then enter BIOS to set as the following.

For K8N Diamond:

Cell Menu-->DRAM Configuration

Timing Mode-->Manual; CAS# Latency-->3;

User Config Mode-->Manual; 1T/2T Memory Timing-->2T;

For P4N Diamond:

Memory Timings-->Manual; CAS Latency-->5/6; Address Mode-->2T;


Then Save&exit setup; Shut down PC, and plug other memory to the MB to verify

The tested settings should be:

AI Over Clock Tuner: Manual


PCI Express Freq: Auto

PCI Freq: 33.33

Performance Mode: Standard

DRAM Timing Selectable: Manual

SDRAM CAS Latency: 3T

SDRAM RAS to CAS Delay (tRCD): 3T (Revised 6/27/2005)

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 8T

SDRAM Write Recovery Time: 4

DDR2 SDRAM Voltage: 2.1

Chipset Core Voltage: 1.7 Volts

All other settings are motherboard defaults.

Maximum DDR2 recommended VDIMM: 2.1 Volts

But only with one set with two sets I would relax the timings more if its not stable.
