Corsair Employee RAM GUY Posted October 20, 2005 Corsair Employee Share Posted October 20, 2005 Can you tell me our modules part# (How To Read the Memory Label) of all of your modules. Link to comment Share on other sites More sharing options...
sboutch Posted October 20, 2005 Author Share Posted October 20, 2005 Hi, I can't find all requested information. The only information, I have is VS512MB266 On the label, there is also this number: 817 - 0539077 - 0 - 568746 On the chip itself, there are: - 38M8BBB - PS 1100540 In the middle of the module, there are: - BP MLL - E186014 - 94V-0 In a corner of the module, there is also this: D68001H That's it Thanks for all Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 20, 2005 Corsair Employee Share Posted October 20, 2005 But you have 2-256 Meg modules listed in your signature. Are you mixing this module with the 2-256 meg sticks? If so please try the system with just our module installed. Link to comment Share on other sites More sharing options...
sboutch Posted October 20, 2005 Author Share Posted October 20, 2005 I have 2x286MB modules: - Spectek - P32M648HHC-75A - PC2100 DDR - S80032VMCTW (on each chip) At first time, I added the new Corsair 512MB module to my existing config, that means 3 slots (out of 4) were used. I don't know exactly if I have to install new module by pair ? It seems no... Now, I'm currently running with only the new 512MB module: after few minutes, it seems to work, but the 2*256MB modules have been worked also. So, is it a problem of compatibility ? If yes, what is it possible to do ? Would it be possible to do some modifications within the BIOS to take into account this specific configuration ? Do you have a BIG Idea ?

Corsair Employee RAM GUY Posted October 21, 2005 Corsair Employee Share Posted October 21, 2005 I would skip the second slot and install the modules in slots 3-4 and then see if it will post and go to bios and set the memory Voltage to 2.7 Volts and then test the system with http://www.memtest.org to be sure.
