Sanchez Posted November 7, 2004 Share Posted November 7, 2004 Hi everyone, OK here is the scoop I have a AMD64 FX53-939 CPU, Gigabyte K8NSXP-939 mobo, 2x512 Corsair XMS4400 DDR550 TwinX RAM, ATI Radeon x800 PRo, 380watt PSU. Now my system is unstable when i use both RAM sticks (SLot1 and 2) especially with gaming. It is somehow stable with 1 RAm stick on slot 1. I have exchanged both sticks in each slot and they both work fine as long as i am only using 1 RAM stick. My mobo is set at 200mhz clock frequency. Now i am frustrated cause i cant use both ram sticks. Is there a known compatibility issues between my RAM and Mobo if so how do i fix this. Thanks the frustrated one.

Corsair Employees RAM GUY Posted November 8, 2004 Corsair Employees Share Posted November 8, 2004 Can you tell me the bios settings you have set for both CPU and memory? Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 8, 2004 Share Posted November 8, 2004 I have seen situations like this before where a small power supply has been the problem. You have a very power hungry system and 380w is most likely not enough. Even if the PSU is not the issue, you may want to consider an upgrade. Mike.

Corsair Employees RAM GUY Posted November 8, 2004 Corsair Employees Share Posted November 8, 2004 I would agree with Mike. It's not so much the peak of the PSU as it is the ability to produce clean power consistently at 250-350 Watts with these systems. And I would suggest at least 430 Watts with your Config. and something like PC Power and Cooling or Ennermax would be a better choice. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted November 9, 2004 Corsair Employees Share Posted November 9, 2004 I would try at the main bios screen hit CNTRL + F1 and then under Frequency and Voltage Control set the Dim or DDR over voltage control to +.2 Volts and then test the system with http://www.memtest.org to make sure it's stable.

Yellowbeard Posted November 9, 2004 Share Posted November 9, 2004 Find the option in your bios to raise the RAM voltage. Raise it up to, but not over, 2.9v. 2.7v-2.9v should be good and is within warranty. Mike. Link to comment Share on other sites More sharing options...
