NTM Posted February 18, 2005 Share Posted February 18, 2005 Hi everybody, I'm new with corsair memories, so I would like to ask experts help me sort out the problem with my 2x 512Mb XMS 3700. All benchmark programs I have tried report that the speed of one of my modules is 3200 insted of 3700. Also some settings you can find bellow are different between modules Please tell me should I be worried about this.

Corsair Employees RAM GUY Posted February 18, 2005 Corsair Employees Share Posted February 18, 2005 Can you tell me the exact model# of your memory module and please tell me if you purchased that module as a pair or set; also what is the CPU speed, and the FSB as well that you have in your system? In addition, please tell me if you have the latest BIOS installed on your system and what BIOS settings you have set for both CPU and memory and any performance settings that you may have set?

NTM Posted February 18, 2005 Author Share Posted February 18, 2005 I forgot to tell you that nothing changed when i changed the memory slots from 1-2 to 2-3 What is realy confusing is that sandra, CPU-Z, NTUNE, read the second module speed is 3200 eventhough the model is declared as 3700. I wouldn't worry about that and I woud take that as a miss reading if I didn't hit the stability issues. Hope that this helps Link to comment Share on other sites More sharing options...
