cdooer Posted September 16, 2008 Share Posted September 16, 2008 Hello. I just put together a system for a friend, which consists of the following; CPU - e2180 MB - Asus P5N-MX (latest bios) RAM - 2 x VS1GB667D2 The problem is, when both memory modules are installed, the system is very unstable, normally booting into Windows only to reboot. When only one module is installed, everything works fine. I sent the memory and the MB back to the place I bought them, and they said they tested them both and everything tested fine. Still the problem persists. I ran memtest (after reading about it on this site) and each module tests fine in the first slot, but when one module is in the second slot (even all by itself) memtest records over 400 errors. All of the settings in the bios are set to auto. Does this sound like an obvious MB problem? Link to comment Share on other sites More sharing options...
DerekT Posted September 16, 2008 Share Posted September 16, 2008 All of the settings in the bios are set to auto. Does this sound like an obvious MB problem? With the correct DRAM (which you have) and that board, clearly you have found the issue. Have you tried inserting the sticks in Slot 2 and Slot 4?

cdooer Posted September 16, 2008 Author Share Posted September 16, 2008 There are only 2 slots on the board, one is yellow, the other is black. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 16, 2008 Corsair Employees Share Posted September 16, 2008 I would check with the MB maker and see what they say but yes that would suggest a problem with the MB or its BIOS version. Link to comment Share on other sites More sharing options...
cdooer Posted September 16, 2008 Author Share Posted September 16, 2008 OK, thanks to both of you. A new BIOS was just released last week for the board, and it yeilds the exact same results. Thanks again, I'll give Asus a shout. Link to comment Share on other sites More sharing options...

cdooer Posted September 16, 2008 Author Share Posted September 16, 2008 OK, just for the fun of it I put both memory modules in and ran memtest again (which I hadn't tried before) and it ran through two passes without any errors. Is it possible that a memory module needs to be installed in slot one in order to use slot two? Still doesn't solve my Windows crashing problem when both DIMMS are installed.

Corsair Employees RAM GUY Posted September 16, 2008 Corsair Employees Share Posted September 16, 2008 What version of Windows are you using? If it's Vista you will need to have SP1 or KB#929777 installed for more then three gig of memory. Link to comment Share on other sites More sharing options...
cdooer Posted September 16, 2008 Author Share Posted September 16, 2008 It's XP SP3. Even with both modules installed in only totals 2GB. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 16, 2008 Corsair Employees Share Posted September 16, 2008 If that is the problem that is a Windows issue if it shows 4 Gig in the BIOS. To be clear what exactly is the problem? Link to comment Share on other sites More sharing options...
cdooer Posted September 17, 2008 Author Share Posted September 17, 2008 When both memory modules are installed, the system boots into Windows and then immediatley reboots. This is continuous. When only one memory module is installed, the system boots into Windows and runs perfectly. I've got two 1GB VS1GB667D2 modules, totalling 2GB (not sure where the reference to 4GB comes from). Regardless of which module I put on the first slot, the system works fine. As soon as I add the second module Windows goes into it's continous reboot problem. Also, the results from memtest are as follows; 1 module in slot 1, no module in slot 2 - no errors 1 module in slot 2, no module in slot 1 - 500 errors 1 module in slot 1, and 1 module in slot 2 - no errors Confusing, eh? It almost seems like there might be something wrong with the second slot, even though memtest doesn't catch it when both slots are populated...but Windows does.

Corsair Employees RAM GUY Posted September 17, 2008 Corsair Employees Share Posted September 17, 2008 Hard to say but if its running now I would not mess with it. But if the system is still displaying this symptom I would try it again and the go to BIOS setup with both modules installed and then load setup defaults and set the memory Voltage to 2.0 Volts and then exit saving changes and see if it will get to windows. Also I would try this if the above does not solve the problem. Please uninstall the Video Driver and see if the system will get to windows with the default Video driver. You can also see if it will get to Windows in safe mode if either of these last two work then it would suggest a driver issue with Windows and I would check with the respective maker.

cdooer Posted September 18, 2008 Author Share Posted September 18, 2008 Hello again. I was playing around with it last night, and noticed that the PC works mint with both sticks of RAM in safe mode, even safe mode with network support. It seems extremely odd that it would work OK with both RAM modules installed in safe mode, but not in normal mode. Any idea Any ideas why safe mode will accept the two GB of RAM, but normal mode will only work with 1GB? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 18, 2008 Corsair Employees Share Posted September 18, 2008 That would suggest it may be a driver or Windows issue. Do you have the latest updates done and all fo the correct drivers for the MB and Video? Link to comment Share on other sites More sharing options...
